    Full Text Available The world buffalo population is about 168 million, and it is still growing, in India, China, Brazil, and Italy. In these countries, buffalo genetic breeding programs have been performed for many decades. The occurrence of congenital malformations has caused a slowing of the genetic progress and economic loss for the breeders, due to the death of animals, or damage to their reproductive ability or failing of milk production. Moreover, they cause animal welfare reduction because they can imply foetal dystocia and because the affected animals have a reduced fitness with little chances of survival. This review depicts, in the river buffalo (Bubalus bubalis world population, the present status of the congenital malformations, due to genetic causes, to identify their frequency and distribution in order to develop genetic breeding plans able to improve the productive and reproductive performance, and avoid the spreading of detrimental gene variants. Congenital malformations most frequently reported in literature or signaled by breeders to the Department of Veterinary Medicine and Animal Production of the University Federico II (Naples, Italy in river buffalo are: musculoskeletal defects (transverse hemimelia, arthrogryposis, umbilical hernia and disorders of sexual development. In conclusion this review put in evidence that river buffalo have a great variety of malformations due to genetic causes, and TH and omphalocele are the most frequent and that several cases are still not reported, leading to an underestimation of the real weight of genetic diseases in this species.

    Simple Summary Congenital malformations (due to genetic causes) represent a hidden danger for animal production, above all when genetic selection is undertaken for production improvements. These malformations are responsible for economic losses either because they reduce the productivity of the farm, or because their spread in the population would decrease the total productivity of that species/breed. River buffalo is a species of increasing interest all over the world for its production abilities, as proved by the buffalo genome project and the genetic selection plans that are currently performed in different countries. The aim of this review is to provide a general view of different models of congenital malformations in buffalo and their world distribution. This would be useful either for those who performed buffalo genetic selection or for researchers in genetic diseases, which would be an advantage to their studies with respect to the knowledge of gene mutations and interactions in this species. Abstract The world buffalo population is about 168 million, and it is still growing, in India, China, Brazil, and Italy.

    This is the first report of Arcobacter spp. in rectal fecal samples from healthy water buffaloes (Bubalus bubalis) reared on a dairy farm. Arcobacter species were isolated after enrichment, and isolates were identified at species level by multiplex-polymerase chain reaction assay. Thirty samples were examined and Arcobacter spp. were isolated from 96.7% of water buffaloes tested: 38 Arcobacter spp. isolates were obtained, with A. cryaerophilus as the dominant species followed by A. butzleri and A. skirrowii. Nine animals (31%) were colonized by more than one Arcobacter species. The present study indicates that water buffaloes can harbor a variety of Arcobacter spp. and that healthy buffaloes may act as hosts. Water buffalo fecal shedding of Arcobacter spp. may be of significance to human health, considering the potential fecal contamination during harvesting of raw milk and slaughtering.

    A number of countries in the world have reported infections with Neospora caninum in water buffalo (Bubalus bubalis), from Africa to Asia, Europe and South America and recently Australia. In general, clinical manifestations (such as abortion) seem rare, which has raised the prospect that buffalo may be inherently resistant to clinical effects of N. caninum infection. Worldwide, the seroprevalence of N. caninum infection (as a measure of exposure determined by the detection of antibody) in buffalo is high, at approximately 48%. This reported seroprevalence is three or four times higher than that reported from the world's cattle populations, which have collective seroprevalence rates of 16.1% for dairy cattle and 11.5% for beef cattle. However, there is a lack of standardisation in seroprevalence studies and some studies may well under-estimate the true level of infection. Epidemiologic evidence supports post-natal transmission, and in utero transmission has also been demonstrated. The causes for water buffalo to have markedly higher seroprevalence but apparently lower neosporosis abortion rates than cattle warrant further investigation.

    This study included 45 unaffected animals and 593 animals affected with heterochromia irides, and 85 enucleated eyeballs with heterochromia irides. The classification of heterochromia irides, morphology of normal and heterochromic irides, and the histology, ultrastructure, and scanning electron microscopy are presented. The incidence of heterochromia irides in water buffaloes was 7.62% affecting either one or both eyes. Both complete and partial heterochromia irides occurred. Complete heterochromia iridis is more frequent than the partial form in either bilateral or unilateral cases. The pupil has a dumb-bell-shape appearance. Granula iridica occurred at the upper (100%) and lower (30%) pupillary margins and originated from the posterior pigmented epithelium. In heterochromia irides, the melanocytes is absent in the anterior border and stromal layers, and iridal thickness appeared thinner than that of normal eyes.

    Full Text Available Abstract Background Microsatellite markers are highly polymorphic and widely used in genome mapping and population genetic studies in livestock species. River buffalo, Bubalus bubalis is an economically important livestock species, though only a limited number of microsatellite markers have been reported thus far in this species. Results In the present study, using two different approaches 571 microsatellite markers have been characterized for water buffalo. Of the 571 microsatellite markers, 498 were polymorphic with average heterozygosity of 0.51 on a panel of 24 unrelated buffalo. Fisher exact test was used to detect LD between the marker pairs. Among the 137550 pairs of marker combination, 14.58% pairs showed significant LD (P Conclusion The high conservation of cattle microsatellite loci in water buffalo promises the usefulness of the cattle microsatellites markers on buffalo. The polymorphic markers characterised in this study will contribute to genetic linkage and radiation hybrid mapping of water buffalo and population genetic studies.

    The water buffalo (Bubalus bubalis) is an important species in several countries for its milk and meat production, as well as for transport and other agricultural activities. It is, in general, considered more resistant than cattle to different parasitic diseases, also less demanding for forage quality. It has been postulated that buffalo may be resistant to abortion caused by neosporosis, because of high serological prevalences found in buffalo herds from different localities, with no description of Neospora caninum-related abortion. Recent studies have demonstrated the potential impact of neosporosis in pregnant water buffalo cows. In this work, three pregnant buffalo cows were experimentally infected with Nc-1 strain of N. caninum, and abortion was detected 35 days post-infection. Molecular and histopathological results found in post-mortem tissues are described and discussed, confirming the susceptibility of water buffalos to abortion caused by N. caninum.

  11. Characterization of PRLR and PPARGC1A genes in buffalo (Bubalus bubalis

    Full Text Available More than 40 million households in India depend at least partially on livestock production. Buffaloes are one of the major milk producers in India. The prolactin receptor (PRLR gene and peroxisome proliferators activated receptor-γ coactivator 1-alpha (PPARGC1A gene are reportedly associated with milk protein and milk fat yields in Bos taurus. In this study, we sequenced the PRLR and PPARGC1A genes in the water buffalo Bubalus bubalis. The PRLR and PPARGC1A genes coded for 581 and 819 amino acids, respectively. The B. bubalis PRLR gene differed from the corresponding Bos taurus at 21 positions and four differences with an additional arginine at position 620 in the PPARGC1A gene were found in the amino acid sequence. All of the changes were confirmed by cDNA sequencing. Twelve buffalo-specific single nucleotide polymorphisms (SNPs were identified in both genes, with five of them being non-synonymous.

    The objective of this study was to explore the possibility of producing wild buffalo embryos by interspecies somatic cell nuclear transfer (iSCNT) through handmade cloning using wild buffalo somatic cells and domestic buffalo (Bubalus bubalis) oocytes. Somatic cells derived from the ear skin of wild buffalo were found to express vimentin but not keratin and cytokeratin-18, indicating that they were of fibroblast origin. The population doubling time of skin fibroblasts from wild buffalo was significantly (p cell proliferation rate was significantly (p cell number (TCN) was significantly (p < 0.05) lower (192.0 ± 25.6 vs 345.7 ± 42.2), and the apoptotic index was significantly (p < 0.05) higher (15.1 ± 3.1 vs 8.0 ± 1.4) for interspecies than that for intraspecies cloned embryos. Following vitrification in open-pulled straws (OPS) and warming, although the cryosurvival rate of both types of cloned embryos, as indicated by their re-expansion rate, was not significantly different (34.8 ± 1.5% vs 47.8 ± 7.8), the apoptotic index was significantly (p < 0.05) higher for vitrified-warmed interspecies than that for corresponding intraspecies cloned embryos (48.9 ± 7.2 vs 23.9 ± 2.8). The global level of H3K18ac was significantly (p < 0.05) lower in interspecies cloned embryos than that in intraspecies cloned embryos. The expression level of HDAC1, DNMT3a and CASPASE3 was significantly (p < 0.05) higher, that of P53 was significantly (p < 0.05) lower in interspecies than in intraspecies embryos, whereas that of DNMT1 was similar between the two types of embryos. In conclusion, these results demonstrate that wild buffalo embryos can be produced by iSCNT.

    Full Text Available To evaluate the subpopulation of corticotrophs in developing buffalo (Bubalus bubalis fetus, recovered pituitary glands (n=6 per group from late first, second and third gestational female buffalo dams. The corticotrophs were identified by using specific antibodies against proopiomelanocortin (POMC and adrenocorticotrophic hormone (ACTH through immunohistochemistry. There was a significant (P≤0.05 increase of immunoreactive (ir ir-ACTH cells during late 2nd trimester while, ir-POMC cells were more (P≤0.05 at late 3rd trimester of gestation as compared to other age groups. The quantity of co-localized cells for POMC and ACTH was significantly (P≤0.05 greater at the end of 1st gestation rather than 2nd and 3rd gestational fetal adenohypophyseal cells. This study is the first to demonstrate co-localization of POMC+ACTH and the affect of gestational age on the expression of these cells in buffalo fetus adenohypophysis.

    2007-06-01

    Full Text Available The binucleate trophoblast cells (CTBs of the water buffalo placenta (Bubalus bubalis were studied with emphasis on the presence of progesterone receptor. Placentomal tissues from 27 buffalos (2-10 months of pregnancy were processed and embedded in paraplast (Paraplast Embedding Media – Paraplast Plus to locate the progesterone receptors using the immunohistochemistry technique. The immunohistochemical reaction for progesterone receptor through monoclonal antibody PgR Ab2 showed staining of CTBs, caruncular epithelial and estromal cells and blood vessel estromal pericitos present in the placentome throughout the entire gestational period analyzed. These results indicate the production of progesterone with autocrine and paracrine action in the placentome growth, differentiation and functional regulation.

    This review deals with the behaviour of river buffaloes (Bubalus bubalis), in confinement and in extensive conditions, also focusing on the effects of different housing and rearing conditions on their welfare. The behavioural repertoire expressed by buffaloes in extensive and intensive conditions is similar to those displayed by other domestic ruminants. However, through natural selection, buffaloes have also acquired several morphological, physiological and behavioural (i.e. wallowing) adaptations to hot climatic conditions. Buffaloes kept in intensive conditions and having no access to pasture and water for wallowing extend their periods of idling and are less often involved in investigative activities. Confinement is also associated with a reduction of space; however, no specific studies have been carried out to determine the specific requirements of this species. Space restriction can adversely affect various aspects of buffalo welfare, such as health (increased levels of lesions and injuries), social behaviour (increased number of agonistic interactions) and heat dissipation. The buffaloes, originating from tropical areas, are well adapted to large variations in food availability and quality, and to dietetic unbalances. As to human animal relationship, it has been observed that the incidence of stepping and kicking behaviour of buffaloes in the milking parlour is positively correlated with the frequency of oxytocin injections, whereas the frequency of positive stockperson interactions with the animals such as talking quietly, petting and gentle touching are negatively correlated with the number of kicks during milking. Data from farms where both dairy cattle and buffaloes are present show that avoidance distance measured in the pen is lower in buffaloes than in cattle. This may be attributed to the fact that buffaloes are generally recognised to be curious animals. Finally, the effects of different farming practices on animal-related indicators are described

    Full Text Available The present study was carried out to describe the clinical picture of traumatic reticuloperitonitis (TRP in water buffalo (Bubalus bubalis and to evaluate the inflammatory and immunologic responses for this clinical condition. Twenty-two buffalo with acute local TRP were monitored in our study. Additionally, 10 clinically healthy buffalo were randomly selected and served as controls. Acute local TRP was initially diagnosed by clinical examination and confirmed by ultrasonographic (USG examination and/or necropsy findings. Blood samples were collected from all examined buffalo to measure the respective levels of tumor necrosis factor alpha (TNF-α, interleukin (IL-1β, IL-6, IL-10 and interferon gamma (INF-γ, serum amyloid A (SAA, C-reactive protein (CRP, haptoglobin (Hp, fibrinogen (Fb, and serum sialic acid (SSA. It was found that TNF-α, IL-1β, IL-6, IL-10, SAA, CRP, Hp, Fb, and SSA were significantly higher in buffalo with TRP than the controls. Our findings suggest that the examined immunologic variables were helpful in documenting the inflammatory response in buffalo with TRP. However, their diagnostic usefulness only becomes apparent when considered in tandem with the clinical findings for any given animal, its anamnesis, and a subsequent USG assessment. Due to the frequent complications of TRP, more accurate indicators of its occurrence and severity would be useful.

    Full Text Available Abstract Background Parainfluenza virus type 3 (PIV3 was isolated from dairy buffaloes (Bubalus bubalis naturally affected with respiratory and reproductive clinical conditions. Results Examination of nasal and vaginal swabs collected from 12 diseased buffaloes led to the isolation of three paramyxovirus isolates from two animals. Antigenic, morphological and biological characteristics of these three isolates were essentially similar to those of members of the Paramyxoviridae family. Antigenic analysis by direct immunofluorescence and cross neutralization test placed these isolates together with bovine parainfluenza virus type 3 (BPIV3. Nucleotide and amino acid phylogenetic analysis of partial matrix gene sequences of the buffalo isolates and six field BPIV3 isolates from bovines in Argentina were studied. Buffalo isolates were similar to genotype B (BPIV3b while the six BPIV3 isolates were similar to genotypes A (BPIV3a and C (BPIV3c. Conclusions This is the first characterization of BPIV3 in water buffalo. According to the samples analyzed, in Argentina, the genotype B was found in buffalo and the genotypes A and C were found in cattle.

    Bovine viral diarrhea virus (BVDV) is an important pathogen that primarily infects ruminants, leading to several clinical problems including abortion. BVDV-specific antibodies were reported in a wide range of hosts within domestic and wildlife animal populations, and serological studies also indicated BVDV infection in buffaloes. The purpose of this study was to analyze the presence of BVDV in 2 water buffalo (Bubalus bubalis) herds with a history of abortion. Virus isolation from aborted fetuses and from maternal buffy coat and the molecular characterization of the isolates confirmed the presence of BVDV in these animals. The sequence analysis based on the 5' UTR and N(pro) coding regions of the Pestivirus genome revealed that the isolates belong to subgenotype 1b of BVDV. The findings of this study also suggest a possible role of BVDV in causing congenital infection in water buffalo. Its presence in fetal tissues as well as in maternal blood raises questions about the possible development of clinical disease or its influence in abortions in water buffalo.

    Full Text Available BACKGROUND: Water buffalo is an economically important livestock species and about half of its total world population exists in India. Development of stem cell technology in buffalo can find application in targeted genetic modification of this species. Testis has emerged as a source of pluripotent stem cells in mice and human; however, not much information is available in buffalo. OBJECTIVES AND METHODS: Pou5f1 (Oct 3/4 is a transcription factor expressed by pluripotent stem cells. Therefore, in the present study, expression of POU5F1 transcript and protein was examined in testes of both young and adult buffaloes by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR and immunohistochemical analysis. Further, using the testis transplantation assay, a functional assay for spermatogonial stem cells (SSCs, stem cell potential of gonocytes/spermatogonia isolated from prepubertal buffalo testis was also determined. RESULTS: Expression of POU5F1 transcript and protein was detected in prepubertal and adult buffalo testes. Western blot analysis revealed that the POU5F1 protein in the buffalo testis exists in two isoforms; large (∼47 kDa and small (∼21 kDa. Immunohistochemical analysis revealed that POU5F1 expression in prepubertal buffalo testis was present in gonocytes/spermatogonia and absent from somatic cells. In the adult testis, POU5F1 expression was present primarily in post-meiotic germ cells such as round spermatids, weakly in spermatogonia and spermatocytes, and absent from elongated spermatids. POU5F1 protein expression was seen both in cytoplasm and nuclei of the stained germ cells. Stem cell potential of prepubertal buffalo gonocytes/spermatogonia was confirmed by the presence of colonized DBA-stained cells in the basal membrane of seminiferous tubules of xenotransplanted mice testis. CONCLUSION/SIGNIFICANCE: These findings strongly indicate that gonocytes/spermatogonia, isolated for prepubertal buffalo testis can

    Full Text Available The present study was conducted to describe the clinical, laboratory and ultrasonographic findings of caecal and colonic dilatation in Egyptian buffalo (Bubalus bubalis. A total number of forty buffaloes were included in the study and divided into two groups: control group (n = 20 and diseased group (n = 20. Diseased buffalo were admitted to the Veterinary Teaching Hospital at Assiut University-Egypt. Each of the diseased animals was subjected to clinical, rectal, laboratory and ultrasonographic examinations. Clinically, buffalo with dilated caecum/colon showed reduced appetite, distended right abdomen, abdominal pain and tensed abdomen. Rectal examination indicated empty rectum with the presence of mucus and dilated loop of caecum and/or colon. Buffalo with dilated caecum/colon showed significant (P < 0.05 hypoproteinemia and hypoalbuminemia with significant (P < 0.05 increase in blood serum activities of aspartate aminotransferase (AST and alkaline phosphatase (ALK. Ultrasonographically, the dilated caecum and proximal loop of colon occupied the last right three intercostal space (ICSs particularly their ventral part, intertangled with the liver dorsally in these ICSs. Dilated colon did not hinder the visibility of the liver. The dilated caecum/colon also filled the whole right flank region, with hiding of right kidney, loops and peristaltic movement of the small intestines. The closest wall of the dilated caecum and proximal loop of the colon was imaged as thick semi-circular echogenic line. The furthest wall and contents of dilated caecum/colon were not imaged. In conclusion, buffalo with caecal and/or colonic dilatation have non-specific clinical and laboratory findings; however the affected animals show characteristic ultrasonographic findings.

    Full Text Available Based on a review of the literature, reference intervals for water buffalo (Bubalus bubalis serum biochemistry and haematology have not previously been published. The current study was done to establish reference intervals for water buffalo heifers. The International Federation of Clinical Chemistry stated that at least 120 values are necessary to obtain reliable estimates for reference intervals. A total number of 127 clinically healthy buffalo heifers (1–2 years old were included in the study. Animals were examined at buffalo farms that belong to Assiut Governorate, Egypt. Three types of samples were collected: serum samples for biochemical analysis, whole blood samples for haematological analysis and faecal samples for parasitological examination. Animals that fitted the inclusion criteria were included in the study. Biochemical analysis included serum total proteins, albumin, total globulins, alpha, beta and gamma globulin levels, and aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transferase, creatine phosphokinase and lactate dehydrogenase activity. In addition to the above, serum creatinine, urea, total bilirubin, direct bilirubin, indirect bilirubin, sodium, potassium, chloride, magnesium, calcium, phosphorus, copper, zinc, iron, triglycerides, high density lipoprotein, low density lipoprotein, very low density lipoprotein, glucose levels and 20 haematological variables were measured. The 95.0% reference intervals were calculated by removing the upper and lower 2.5% of the interval for each serum biochemical constituent to give the 2.5 and 97.5 percentiles. Confidence intervals were calculated for each reference limit. Reference intervals from the current study were compared with established values for cows. The current study is as far as could be determined the first that establishes reference intervals for the serum biochemical and haematological parameters in water buffalo heifers.

    Infection of water buffaloes (Bubalus bubalis) with bovine viral diarrhea viruses (BVDV) has been confirmed in several studies by serological and molecular techniques. In order to determine the presence of persistently infected animals and circulating species and subtypes of BVDV we conducted this study on a buffalo herd, whose habitat was shared with bovine cattle (Bossp.). Our serological results showed a high level of positivity for BVDV-1 and BVDV-2 within the buffalo herd. The molecular analyses of blood samples in serologically negative animals revealed the presence of viral nucleic acid, confirming the existence of persistent infection in the buffaloes. Cloning and sequencing of the 5' UTR of some of these samples revealed the presence of naturally mix-infected buffaloes with at least two different subtypes (1a and 1b), and also with both BVDV species (BVDV-1 and BVDV-2).

    Background: There is a little or no data available on the natural Babesia bovis (B. bovis) infection in water buffaloes (Bubalus bubalis) comparing to the available one for cattle. This study was conducted to investigate the natural B. bovis infection in water buffaloes in comparison to crossbred...... of cattle showed dark brown to dark red (coffee-color) urine, hemoglobinuria and nervous manifestations while these manifestations were not detected in the infected buffaloes. Hematological changes in both species however, these changes were less significant in buffaloes than those reported in cattle....... Conclusion: This paper documents the first description of natural B. bovis infection in water buffaloes which were found to be more likely to be tolerant than cattle to the natural clinical infection with B. bovis and its subsequent haematological changes. Our finding may lead to a better understanding...

    We conducted a molecular epidemiological survey of Cryptosporidium and Giardia from Bubalus bubalis (water buffalo) on two extensive farms (450 km apart) in Victoria, Australia. Faecal samples (n=476) were collected from different age groups of water buffalo at two time points (six months apart) and tested using a PCR-based mutation scanning-targeted sequencing-phylogenetic approach, employing markers within the small subunit of ribosomal RNA (designated pSSU) and triose phosphate isomerase (ptpi) genes. Based on pSSU data, Cryptosporidium parvum, Cryptosporidium bovis and Cryptosporidium genotypes 1, 2 (each 99% similar genetically to Cryptosporidium ryanae) and 3 (99% similar to Cryptosporidium suis) were detected in two (0.4%), one (0.2%), 38 (8.0%), 16 (3.4%) and one (0.2%) of the 476 samples tested, respectively. Using ptpi, Giardia duodenalis assemblages A and E were detected in totals of 56 (11.8%) and six (1.3%) of these samples, respectively. Cryptosporidium was detected on both farms, whereas Giardia was detected only on farm B, and both genera were detected in 1.5% of all samples tested. The study showed that water buffaloes on these farms excreted C. parvum and/or G. duodenalis assemblage A, which are consistent with those found in humans, inferring that these particular pathogens are of zoonotic significance. Future work should focus on investigating, in a temporal and spatial manner, the prevalence and intensity of such infections in water buffaloes in various geographical regions in Australia and in other countries.

    Full Text Available Background: Leptin, as a 16 kDa adipokine, is a pleiotropic cytokine-like hormone that primarily secreted from adipose tissue. It also involves in the regulation of energy homeostasis, neuroendocrine function, immunity, lipid and glucose homeostasis, fatty acid oxidation, angiogenesis, puberty and reproduction. The aim of this study was to investigate the effects of in vitro addition of leptin to in vitro maturation (IVM medium on buffalo oocyte maturation and apoptosis. Materials and Methods: In this experimental study, Ovaries from apparently normal reproductive organs of slaughtered adult buffaloes (Bubalus bubalis with unknown breeding history were collected from Urmia Abattoir, Urmia, Iran, and were transported immediately to the laboratory in a thermos flask containing sterile normal saline with added antibiotics. Oocytes were aspirated from 2-8 mm visible follicles of the ovaries using an 18-G needle attached to a 10 ml syringe. IVM medium included tissue culture medium-199 (TCM-199, 10% fetal bovine serum (FBS, 22 μg/ml sodium pyruvate, 0.5 IU/ml ovine follicle-stimulating hormone (oFSH, 0.5 IU/ml ovine luteinizing hormone (oLH, 1 μg/ml oestradiol, 50 μg/ml gentamycin, and leptin [0 (control, 10, 50, and 100 ng/ml]. The good quality buffalo oocytes (batches of 10 oocytes were placed in a culture plate containing six 50 μl droplets of maturation medium, covered with sterilized mineral oil, and then incubated at 38.5˚C with 5% CO2 in air for 24 hours. The maturation of oocytes was evaluated under a stereomicroscope by detecting the first polar body extrusion of oocytes. FITC-Annexin V - propidium iodide (PI staining method was used to detect oocyte apoptosis. Results: From a total of 115 collected ovaries, 1100 oocytes were recovered among which 283 oocyte were suitable for IVM.

    The seroprevalence of Neospora caninum infection in water buffalo (Bubalus bubalis) and domestic cattle in the Northern Territory (NT) of Australia has never been determined. A total of 480 serum samples from water buffalo and 192 serum samples from cattle, collected by the NT Government from 1993 through to 2001, at 18 different survey sites throughout the Northern Territory were tested by commercial ELISA for anti-N. caninum antibodies. The water buffalo samples demonstrated a seroprevalence of 88.3% (95% CI ± 2.9%), while 31.8% (±6.1%) of the cattle sera tested positive for N. caninum antibodies. Individual buffalo from the same herd, sampled over years, showed considerable fluctuations in S/P ratios. Overall, seropositivity was consistent across buffalo herds, and showed a slight decline over the years. The study presents evidence for the first time that N. caninum infection in water buffalo in the Northern Territory is a highly endemic and that infection rates are higher than those for cattle. This is important for an understanding of any potential sylvatic life cycle of N. caninum in Northern Australia. This survey also tests cattle from that territory for the first time for evidence of N. caninum infection and makes an important contribution to the understanding of disease management issues for the beef industry in the region.

Split pooled buffalo bull ejaculates were diluted in TCA egg yolk glycerol extender containing either vitamin C (TCAC, vitamin E (TCAE or without antioxidant (TCAN at 37°C. Extended semen was cooled to 4C in 2 h and equilibrated for 4 h at 4C. Cooled semen was then filled in 0.5 ml straws at 4C and frozen in programmable cell freezer. Thawing of semen was performed at 37°C for 30 seconds. Sperm motility, plasma membrane integrity and sperm morphology (acrosome integrity, head, mid-piece and tail abnormalities of each semen sample were evaluated. Percentage of post-thaw spermatozoal motility assessed visually at 0 and 6 h and the post-thaw percentage of spermatozoa with intact plasma membranes at 0 h were higher (P0.05. In conclusion, non-enzymatic antioxidants, particularly vitamin E, in the tris citric acid extender may improve the quality of frozen-thawed buffalo bull spermatozoa.

    Ectopically, expression of defined factors could reprogram mammalian somatic cells into induced pluripotent stem cells (iPSCs), which initiates a new strategy to obtain pluripotent stem cell lines. Attempts have been made to generate buffalo pluripotent stem cells by culturing primary germ cells or inner cell mass, but the efficiency is extremely low. Here, we report a successful method to reprogram buffalo fetal fibroblasts (BFFs) into pluripotent stem cells [buffalo induced pluripotent stem cell (biPSCs)] by transduction of buffalo defined factors (Oct4, Sox2, Klf4, and c-Myc) using retroviral vectors. The established biPSCs displayed typical morphological characteristics of pluripotent stem cells, normal karyotype, positive staining of alkaline phosphatase, and expressed pluripotent markers including Oct4, Sox2, Nanog, Lin28, E-Cadherin, SSEA-1, SSEA-4, TRA-1-81, STAT3, and FOXD3. They could form embryoid bodies (EBs) in vitro and teratomas after injecting into the nude BALB/C mice, and 3 germ layers were identified in the EBs and teratomas. Methylation assay revealed that the promoters of Oct4 and Nanog were hypomethylated in biPSCs compared with BFFs and pre-biPSCs, while the promoters of Sox2 and E-Cadherin were hypomethylated in both BFFs and biPSCs. Further, inhibiting p53 expression by coexpression of SV40 large T antigen and buffalo defined factors in BFFs or treating BFFs with p53 inhibitor pifithrin-a (PFT) could increase the efficiency of biPSCs generation up to 3-fold, and nuclear transfer embryos reconstructed with biPSCs could develop to blastocysts. These results indicate that BFFs can be reprogrammed into biPSCs by buffalo defined factors, and the generation efficiency of biPSCs can be increased by inhibition of p53 expression. These efforts will provide a feasible approach for investigating buffalo stem cell signal pathways, establishing buffalo stem cell lines, and producing genetic modification buffaloes in the future.

    Objective:To assess normal conjunctival cytological and bacteriological/fungal flora features in the Mediterranean buffalo (Bubalus bubalis). Methods:Swabs were taken from the inferior conjunctival sac of both eyes of 57 healthy female buffaloes aged 24-36 months, with no evidence of ocular disease, farmed in Campania region (Southern Italy), for microbiological analysis. Conjunctival eye specimens of both eyes were subsequently obtained by a cyto-brush, for cytological analysis. The antimicrobial susceptibility of bacterial isolates was also determined using the disk-diffusion method on Mueller Hinton agar plates. Results: Cytological examination of conjunctival swab specimens (114 eyes) revealed epithelial cells (basal, intermediate, columnar and superficial) in all samples, whereas neutrophils, lymphocytes and plasma cells were present in 70%, 10%and 2%of samples, respectively. Microorganisms, for a total of 261 aerobic bacteria and 6 fungi, were isolated from 112/114 conjunctival samples (98.25%;95%confidence interval (CI):93.18–99.70). Only two conjunctival swabs did not yield bacteria and/or fungi (2/114, 1.75%;95% CI:0.30–6.82). Gram-positive aerobes were most commonly cultured (181/261, 69.35%;95%CI: 63.31–74.81), with Enterococcus faecium and Staphylococcus lentus predominating. Escherichia coli was the most frequently isolated as Gram-negative bacteria (80/261, 30.65%;95%CI:25.19–36.69). The antimicrobial resistance patterns of the isolated bacteria showed amoxycillin/clavulanic acid and cephalothin as the least sensitive antibiotics for both Gram-positive and Gram-negative bacteria. Conclusions: These results provided first information on normal conjunctival ocular microflora and cytological features in Mediterranean buffalo.

    The use of live vaccine strain RB51 for vaccination of domestic water buffaloes (Bubalus bubalis) at risk of infection with Brucella abortus is permitted notwithstanding the plans for the eradication and only under strict veterinary control. The antibodies induced by RB51 vaccination are not detectable using conventional diagnostic techniques; therefore, it is necessary to have a specific diagnostic tool able to discriminate vaccinated from unvaccinated animals. The combination of a complement fixation test (CFT) with specific RB51 antigen (RB51-CFT) and a brucellin skin test has been demonstrated to be a reliable diagnostic system to identify single cattle (Bos taurus) vaccinated with RB51. So far, no data are available in the international scientific literature regarding the use of this test association in water buffalo. For this reason the suitability of this test combination has been evaluated in a water buffalo herd. One hundred twenty-seven animals farmed in a herd of Salerno province (Campania, Southern Italy), in the context of a presumptive unauthorized use of RB51 vaccine were chosen for this study. All tested animals resulted negative to Rose Bengal test (RBT) and complement fixation test (CFT) used for the detection of specific antibodies against Brucella field strains. Seventy-one animals (56%) developed RB51 antigen-specific CFT (RB51-CFT) antibodies against RB51 vaccine in a first sampling, while 104 animals (82%) gave positive result to a second serum sampling conducted 11 days after the intradermal inoculation of the RB51 brucellin. One hundred and seven animals (84%) showed a positive reaction to the RB51-CFT in at least 1 sampling, while 111 animals (87%) resulted positive to the RB51 brucellin skin test. Thus, analysing the results of the 3 testing in parallel, 119 animals (94%) were positive to at least 1 of the performed tests. The results suggest that the use in parallel of the RB51 brucellin skin test with RB51-CFT may represent a reliable

    Aim:To test the hypothesis that season affects the semen quality of swamp buffalo (Bubalus bubalis) bulls used for artificial insemination (AI) under tropical conditions in Thailand, as it does in Bos taurus and Bos indicus. Methods: Clinical and andrological examinations, and monitoring of semen production and quality were carried out on five mature, healthy swamp buffalo AI bulls in Thailand from July 2004 to the end of June 2005. Sperm output, motility, morphology and plasma membrane integrity (PMI) were compared between three seasons of the year (rainy, I.e. July-October; winter, I.e. November-February; and summer, I.e. March-June) with distinct ambient temperature and humidity. Results: All bulls were diagnosed as clinically healthy and with good libido throughout the study. Ejaculate volume, pH, sperm concentration, total sperm number and initial sperm motility did not differ between seasons, whereas PMI and the relative proportion of morphologically normal spermatozoa were highest in summer and lowest in winter (P < 0.05). Buffalo age, week of collection and season influenced sperm morphology (P < 0.05-0.001). Among morphological abnormalities,only proportions of tail defects were affected by season, being highest in the rainy season and lowest in summer (P<0.001). In conclusion, climatic changes did not seem to largely affect semen sperm output or viability. Although the proportions of PMI and tail abnormalities were affected by season, they were always below what is considered unacceptable for AI bull sires. Conclusion: Seasonal changes did not appear to cause deleterious changes in sperm quality in swamp buffalo AI-sires in tropical Thailand.

    Full Text Available The buffalo (Bubalus bubalis not only is a useful source of milk, it also provides meat and works as a natural source of labor and biogas. To establish a project for buffalo genome mapping a 5,000-rad whole genome radiation hybrid panel was constructed for river buffalo and used to build preliminary RH maps from two chromosomes (BBU 3 and BBU10. The preliminary maps contain 66 markers, including coding genes, cattle ESTs and microsatellite loci. The RH maps presented here are the starting point for mapping additional loci, in particular, genes and expressed sequence tags that will allow detailed comparative maps between buffalo, cattle and other species to be constructed. A large quantity of DNA has been prepared from the cell lines forming the RH panel reported here and will be made publicly available to the international community both for the study of chromosome evolution and for the improvement of traits important to the role of buffalo in animal agriculture.

    Four rumen-fistulated swamp buffaloes (Bubalus bubalis) were randomly allocated to investigate rumen adaptation of urea on feed intake, nutrient digestibility, fermentation efficiency, and microbial protein synthesis. Buffaloes were fed with rice straw ad libitum for a period of 2 weeks and then were shifted to a step-up diet regimen by supplementation of concentrate containing 20 and 40 g/kg urea at 5 g/kg BW for a period of 2 and 4 weeks, respectively. The results revealed that feed intake and nutrient digestibility were increased by urea supplementation (P urea nor adaptation period (P > 0.05) while bacterial and fungal zoospores were increased especially at 40 g/kg urea. Data from real-time PCR further showed that total bacteria and the three predominant cellulolytic bacteria (Ruminococcus albus, Fibrobacter succinogenes, Ruminococcus flavefaciens) were increased by urea supplementation both at 2 and 4 weeks of urea feeding. Furthermore, methane production was similar among treatments while microbial protein synthesis was enhanced when buffaloes were fed with urea after a period of 2 weeks especially at 40 g/kg urea (P urea supplementation could increase feed intake, nutrient digestibility, microbial protein synthesis, and fermentation efficiency of swamp buffaloes fed on rice straw. It is suggested that buffaloes could adapt well and utilize urea as a N source effectively within a period of 2 weeks uptake without adverse effect.

    Full Text Available Forty clinically healthy Nili-Ravi buffaloes (Bubalus bubalis were divided into two age groups of 20 animals each viz., young (12-48 months of age and adult (49-96 months of each sex. These studies revealed that the absolute heart weight, absolute kidney’s weight, the absolute adrenal gland’s weight, mean values of width of heart, circumference, thickness of wall of right and left atria, thickness of wall of right and left ventricles, mean values of length of right and left kidneys, width, circumference, mean values of length of the adrenal glands were significantly (P<0.05 higher in adult buffaloes than young ones. The average relative heart weight, relative kidneys weight and the relative weight of adrenal glands was significantly (P<0.01 higher in young buffaloes as compared to the adult ones. While the relationship of the width of right adrenal glands between young and adult buffaloes were recorded as non-significant. The results of the present study are the first report on the age related morphological changes in the heart, kidneys and adrenal glands of buffalo. These age induced anatomical changes may affect the rennin-angiotensin-aldosterone system (RAAS and hence blood pressure of an individual.

    Full-length cDNA (435 bp) of the interleukin-3(IL-3) gene of the Indian water buffalo was amplified by reverse transcriptase-polymerase chain reaction and sequenced. This sequence had 96% nucleotide identity and 92% amino acid identity with bovine IL-3. There are 10 amino acid substitutions in buffalo compared with that of bovine. The amino acid sequence of buffalo IL-3 also showed very high identity with that of other ruminants, indicating functional cross-reactivity. Structural homology modelling of buffalo IL-3 protein with human IL-3 showed the presence of five helical structures.

    Lumpy skin disease virus (LSDV), sheep poxvirus (SPV) and goat poxvirus (GPV) are the most serious poxviruses of ruminants. In this study, we analysed the G-protein-coupled chemokine receptor (GPCR) genes of LSDV isolates from cattle and water buffalo (Bubalus bubalis) in Egypt during the summer of 2011. Multiple alignments of the nucleotide sequences revealed that the water buffalo LSDV isolate differed from the cattle isolate at four nucleotide positions, and both isolates had nine nucleotide mutations from the reference strain, Egyptian tissue culture-adapted cattle LSDV/Ismailyia88 strain. Compared with the GPCR sequences of SPV and GPV strains, a 21 nucleotide insertion and a 12 nucleotide deletion were identified in the GPCR genes of our used isolates and other LSDVs. The amino acid sequences of GPCR genes of our isolates contained the unique signature of LSDV (A11 , T12 , T34 , S99 and P199 ). Phylogenetic analyses showed that the GPCR genes of cattle and water buffalo LSDVs were closest genetically, indicating a potential transmission of cattle LSDV to water buffalo.

    Full Text Available Water buffalo are of great economic importance in Brazilian Amazonia, which has the largest herd in Brazil. Bovine tuberculosis caused by Mycobacterium bovis is a zoonotic disease that results in severe losses to water buffalo production. Although the disease has already been described in the country, data on the occurrence and distribution of bovine tuberculosis in water buffalo in Brazil is very scarce. The aim of this study was to determine the frequency of bovine tuberculosis in water buffalo in the Baixo Araguari River region of Amapá, Brazil. Thirty herds, randomly selected from the 41 herds of water buffalo in the region, were sampled. From those herds, 212 randomly selected water buffalo were subjected to the comparative tuberculin skin test. The proportion of Baixo Araguari River region herds that were positive for bovine tuberculosis was 50.0% (95% CI 31.3% to 68.7% and the proportion of animals that were positive was estimated to be 14.8% (95% CI 7.8% to 21.9%. Our results show that bovine tuberculosis is spread widely among water buffalo in the Baixo Araguari River region, which suggests that measures to control the disease should be undertaken in the region.

    Full Text Available Forty lactating Greek buffalo cows were used in an experiment to determine effects of parity and calf birth month onproductivity and milk composition. Buffalo cows gave birth on months June and August 2009, and were kept undersemi closed system of management. From June to November, during the day the buffalo cows were allowed to grazeon the surroundings from 10:00 h and flocked back at 16:00 h. In the experiment, which started on week 6postpartum and lasted 24 weeks, buffalo cows were fed alfalfa hay, corn silage, wheat straw and concentrate, andwere allocated, relative to parity, into treatments GBP1 (21 buffalo cows with parity 1, 2, and 3 and GBP2 (19buffalo cows with parity 4, 5, and 6, and, relative to calf birth month, into treatments GBB1 (20 buffalo cows withJune as calf birth month and GBB2 (20 buffalo cows with August as calf birth month. Productivity and milkcomposition were not affected (P>0.05 by calf birth month. During the experiment, there were differences(P<0.001 between GBP1 and GBP2 treatments in average milk yield (4.1 vs. 5.3 kg/day, fat yield (0.33 vs. 0.41kg/day, protein yield (0.19 vs. 0.24 kg/day, lactose yield (0.21 vs. 0.27 kg/day and ash yield (0.033 vs. 0.044kg/day. In contrast, milk fat (80.8 g/kg, protein (45.9 g/kg, lactose (51.2 g/kg and ash (8.2 g/kg contents, as wellas somatic cell counts (82.9 ×1000/ml and colony forming units (44.9 ×1000/ml, were not affected (P>0.05 byparity. Milk production and quality of Greek buffalo is generally satisfactory, and may be economically beneficialfor local breeders.

    Buffalo colostrum caused lysis of unsensitized red blood cells (RBC) from sheep, goats, rabbits and chickens. RBC from cattle and buffalo were resistant to lysis. That lysis was due to the presence of natural antibodies to these RBC was ruled out since there was no reduction in haemolytic titres even after adsorption with the respective RBC. The addition of EGTA to the diluent had no effect on the haemolytic activity. These findings indicate the presence of alternative complement pathway (ACP) activity in buffalo colostrum. The haemolytic activity of buffalo complement for unsensitized rabbit RBC was reduced to very low levels by heating at 50 degrees C for 45 min. Treatment with zymosan also inhibited the haemolytic activity, while inulin had no effect. The maximum activity of ACP occurred in the presence of 4 mmol/L Mg(2+) in the diluent. The range of ACP activities in colostrum from buffaloes varied from 4.06 to 8.48 CH50 units/ml. Using a standard system for titrating the classical complement pathway and rabbit red blood cells sensitized with goat haemolysin, the range of complement activity in buffalo colostrum was 4.81-6.77 CH50/ml.

    Full Text Available Six clinically healthy male water buffaloes (Bubalus bubalis 2–3 years of age and weighing 290–325 kg were used for 2 different treatments (H1 andH2. The animals of groupH1 were premedicated with medetomidine (2.5 g/kg, i.v. and butorphanol (0.05 mg/kg, i.v., while in groupH2 midazolam (0.25 mg/kg and butorphanol (0.05 mg/kg were used intravenously. Induction of anaesthesia was achieved by 5%thiopental sodium inH1 (3.85±0.63 mg/kg and H2 (6.96 ± 0.45 mg/kg groups. The anaesthesia was maintained with halothane in 100 % oxygen through a large animal anaesthetic machine. Better analgesia and sedation with a significantly lower dose of thiopental for induction and significantly higher values of sternal recumbency time and standing time were recorded in group H1 than in group H2 , whereas no significant (P > 0.05 difference for the halothane concentration was observed between groups H1 and H2. Significant decrease in heart rate was observed in group H1 whereas it significantly increased in group H2. In both groups, RR decreased during the preanaesthetic period, which increased significantly (P<0.01 after halothane administration. In both groups a significant (P<0.01 fall in RT was recorded from 20 min to the end of observation period. A significant (P < 0.05 fall in MAP was observed in group H1 from 15 min until the end, while in group H2 MAP increased nonsignificantly (P > 0.05 after premedication and a significant (P<0.05 occurredafter thiopental administration. In both groups a significant (P<0.01 increase in CVP and a significant (P<0.01 decrease in SpO2 were observed after premedication which persisted up to 120 min. ECG changes included significant (P<0.01 decrease and increase in QRS amplitudes in groupsH1 andH2 respectively, a significant (P < 0.05 increase in PR interval was recorded at 15 min in group H1, a significant (P<0.05 decrease in PR interval in groupH2 , a significant (P<0.05 decrease in T wave amplitude in groupH1, and a

    Full Text Available Back ground: The vulnerability of the buffalo to the luxation of the hip articulation previous to and during parturition encouraged the investigation in this species. The literature reviewed did not reveal complete anatomical descriptions of the coxofemoral articulation of buffalo. Hence the study was undertaken. Purpose: to study the different anatomical aspects of the hip joint which are specific to buffaloes. Methods and Results: A total number of fifteen hip joints of buffalo calves procured from the local slaughter house and department of Veterinary Anatomy were studied in the Department of Veterinary Anatomy, College of Veterinary Science, Tirupati irrespective of breed, sex and nutritional status. The gross morphology of joints and relations were studied. The round ligament of buffalo was stronger compared to cattle. A thick fibrous stratum of articular capsule was present. A few arched and semi-circular fibers were seen in the articular capsule but zona orbicularis was absent. The best developed periarticular ligament in the buffalo hip was the iliofemoral ligament. It was a thick cord of connective tissue extending from a nodule below and behind the ischiatic spine and spreaded over the capsula articularis and finally attached to the trochanter major and trochanteric ridge. The pubocapsular ligament was located on the ventral surface of the joint capsule and blended with it. Compared to the most of other quadripeds the periarticular ligaments were well developed in buffalo. The iliofemoral ligament was mostly helpful in preventing the hip from excessive extension and adduction. The relative development of the periarticular ligaments in the biped and quadrupeds were probably in accordance with comparative weight that this articulation must support. Potential implications: An understanding of the basic anatomy of the hip helps in understanding pathology and can greatly assist the surgeon in appropriately diagnosing and treating the

    Egg yolk is routinely used as a cryoprotectant in semen extenders. However, it may contain cryoprotective antagonists, and there are hygienic risks associated with its use. Proteins of plant origin, like soya-lecithin, lack these hazards. The aim of this study was to use soya-lecithin as a cryoprotectant in extender and to investigate its effects on in vitro quality and in vivo fertility of buffalo semen. Semen from three buffalo bulls was frozen in tris-citric extender containing 5.0%, 10% or 15% soya-lecithin or 20% egg yolk. Sperm motility, plasma membrane integrity and viability were assessed post-dilution, pre-freezing and post-thaw. In Post-dilution and pre-freezing, the values for motility, plasma membrane integrity and viability remained higher (p ≤ 0.05) in extenders containing 10% soya-lecithin and control compared with extender containing 5% and 15% soya-lecithin. However, motility, plasma membrane integrity and viability were higher (p soya-lecithin compared with control and extenders containing 5% and 15% soya-lecithin. Semen from two buffalo bulls was frozen in tris-citric extender containing either 10% soya-lecithin or 20% egg yolk. Higher (p soya-lecithin (56%) compared with 20% egg yolk (41.5%). The results suggest that 10% soya-lecithin in extender improves the freezability and fertility of buffalo bull spermatozoa and can be used as an alternate to egg yolk in cryopreservation of buffalo semen.

    Bovine immunodeficiency is a chronic progressive disease caused by a lentivirus that affects cattle and buffaloes. Although the infection has been described in cattle in some countries, including in Brazil, there are only two reports of infection in buffaloes: one in Pakistan and one in Cambodia. The aim of the present study was to survey the occurrence of bovine immunodeficiency virus (BIV) in water buffaloes from the Amazon region, Pará state, Brazil. BIV proviral DNA was surveyed in 607 whole blood samples of water buffaloes from 10 farms located in the state of Pará using semi-nested polymerase chain reaction (PCR) (PCR-SN) to amplify the pol region of the viral genome. Of the 607 samples tested, 27 (4.4 %) were positive for BIV proviral DNA. The amplified fragments were confirmed by sequence analysis after cloning and nucleotide sequencing. The sequence obtained had 99 % similarity to the reference strain (R-29). The present study provides important epidemiological data because BIV was detected for the first time in water buffaloes in Brazil. Further, the results suggest the possibility of the virus being a risk factor for herd health because it may be a potential causal agent of chronic disease and, also may be associated to other infectious diseases.

    Full Text Available Gross and microscopical aspects of the buffalo pineal gland were described in seasonal parturition animals, since this gland is responsible for melatonin secretion which acts upon the hypothalamus-hypophysis reproductive axis feedback system. (Hafez, 1995. For the present study, 11 cross-bred buffaloes, predominantly of the Mediterranean breed, from the Pirassununga Campus - USP (University of São Paulo, were killed in different photoperiods in the slaughterhouse. The pineal glands were obtained, fixed, weighed, measured, photographed, processed, cut into sections and stained. All glands demonstrated the same global shape, with a mean length of 8.82 ± 1.07mm and a width of 7.91 ± 0.83mm, and a stem length of 5.50 ± 4.18mm. The stems had a microscopically visible lumen. The mean gland weight was 251.45 ± 83.1mg. The buffalo pineal gland presented right and left lobes of different sizes. Microscopically, they were surrounded by a connective tissue layer with blood vessels infiltrating into the glandular parenchyma, which became separated into glial cell lobules. A great number of the pinealocytes were arranged in irregular strings, and cells from the connective tissue could be observed in the glandular parenchyma. We conclude that the buffalo pineal gland is similar to that of pineal cows and that it does not show morphologic alterations during different photoperiods of the year.

    Full Text Available Buffaloes mostly suffer from delayed puberty, anestrus, sub–estrus, summer infertility, prolonged inter-calving interval and postpartum uterine disorders. Nesfatin-1 and Leptin are directly or indirectly related with body weight (BW, feed parameters and regulation of puberty. The objective of this study was to investigate the influence of Nesfatin-1 and Leptin in pubertal and non-pubertal Murrah buffalo heifers. The Murrah buffalo heifers (n=13 were randomly selected and divided into two groups; pubertal group (PG and non-pubertal group (NG. Heifers with plasma progesterone (P4 level of ≥1 ng/mL were classified as PG. Blood samples were collected at fortnight intervals for analysis of plasma Nesfatin-1, Leptin, P4, glucose and non-esterified fatty acids. Body weight, dry matter intake and feed conversion efficiency were recorded at fortnight intervals. The mean (±SEM plasma Nesfatin-1, Leptin, P4, BW and feed conversion efficiency (% were significantly (P<0.01 higher in PG as compared to NG. Dry matter intake by the heifers was also significantly (P<0.001 higher in PG than NG. Plasma metabolites (glucose and NEFA did not differ significantly between the groups. The findings of this study suggest that Nesfatin-1 and Leptin have indispensable role in the onset of puberty in buffalo heifers by affecting BW and feed parameters.

Highlights: Black-Right-Pointing-Pointer Collagen-IV matrix is found cytocompatible for EBs formation and differentiation. Black-Right-Pointing-Pointer Established 3D microenvironment for ES cells development and differentiation into three germ layers. Black-Right-Pointing-Pointer Collagen-IV may be useful as promising candidate for ES cells based therapeutic applications. -- Abstract: Embryoid bodies (EBs) are used as in vitro model to study early extraembryonic tissue formation and differentiation. In this study, a novel method using three dimensional extracellular matrices for in vitro generation of EBs from buffalo embryonic stem (ES) cells and its differentiation potential by teratoma formation was successfully established. In vitro derived inner cell masses (ICMs) of hatched buffalo blastocyst were cultured on buffalo fetal fibroblast feeder layer for primary cell colony formation. For generation of EBs, pluripotent ES cells were seeded onto four different types of extracellular matrices viz; collagen-IV, laminin, fibronectin and matrigel using undifferentiating ES cell culture medium. After 5 days of culture, ESCs gradually grew into aggregates and formed simple EBs having circular structures. Twenty-six days later, they formed cystic EBs over collagen matrix with higher EBs formation and greater proliferation rate as compared to other extracellular matrices. Studies involving histological observations, fluorescence microscopy and RT-PCR analysis of the in vivo developed teratoma revealed that presence of all the three germ layer derivatives viz. ectoderm (NCAM), mesoderm (Flk-1) and endoderm (AFP). In conclusion, the method described here demonstrates a simple and cost-effective way of generating EBs from buffalo ES cells. Collagen-IV matrix was found cytocompatible as it

    2008-03-01

    Lectins are carbohydrate-binding proteins present in a wide variety of plants and animals, which serve various important physiological functions. A soluble beta-galactoside binding lectin has been isolated and purified to homogeneity from buffalo brain using ammonium sulphate precipitation (40-70%) and gel permeation chromatography on Sephadex G50-80 column. The molecular weight of buffalo brain lectin (BBL) as determined by SDS-PAGE under reducing and non-reducing conditions was 14.2 kDa, however, with gel filtration it was 28.5 kDa, revealing the dimeric form of protein. The neutral sugar content of the soluble lectin was estimated to be 3.3%. The BBL showed highest affinity for lactose and other sugar moieties in glycosidic form, suggesting it to be a beta-galactoside binding lectin. The association constant for lactose binding as evidenced by Scatchard analysis was 6.6 x 10(3) M(-1) showing two carbohydrate binding sites per lectin molecule. A total inhibition of lectin activity was observed by denaturants like guanidine HCl, thiourea and urea at 6 M concentration. The treatment of BBL with oxidizing agent destroyed its agglutination activity, abolished its fluorescence, and shifted its UV absorption maxima from 282 to 250 nm. The effect of H2O2 was greatly prevented by lactose indicating that BBL is more stable in the presence of its specific ligand. The purified lectin was investigated for its brain cell aggregation properties by testing its ability to agglutinate cells isolated from buffalo and goat brains. Rate of aggregation of buffalo brain cells by purified protein was more than the goat brain cells. The data from above study suggests that the isolated lectin may belong to the galectin-1 family but is glycosylated unlike those purified till date.

Evaluate the results of the standardization of the in vitro production program of buffalo embryos, using oocytes obtained by ultrasound guided oocyte puncture during the 2012 breeding season in Colombia. Materials and methods. Fifty seven buffalo females were selected for ultrasound guided transvaginal aspiration of follicles, oocytes were identified within follicular fluid, classified and transported to the laboratory and matured in vitro for 18 to 20 hours. Frozen semen of seven Mediterranean bulls were used, motile sperm was obtained using the Percoll technique and oocytes were inseminated with 2 million sperm/ml. Presumptive zygotes were cultured for 6 days, grade 1 embryos obtained were frozen using ethylene glycol. Embryos were transferred to females on day 5 during natural cycle. Results. 97 aspirations were performed on the 57 animals, in 8.2% of the aspirations no oocytes were found. 8 oocytes/aspiration were obtained. Of the 783 oocytes, 92% were classified as viable (721/783 and were fertilized. The cleavage and blastocyst rate were 23% and 19% respectively. 37 embryos were transferred and 11 pregnancies were obtained, confirmed by rectal palpation 60 days after transfer, with a pregnancy rate of 29.7%. Conclusions. The results presented here are comparable with others in literature and shows the feasibility of producing in vitro embryos and pregnancies after the standardization of current protocols, with normal and sexed semen and transfer during natural cycle in buffalo.

    Full Text Available Aim: The aim of this study was to investigate the effect of incubation on freezability of cholesterol loaded cyclodextrin (CLC treated buffalo spermatozoa. Materials and Methods: Semen samples with mass motility of 3+ and greater, collected from Murrah buffalo bulls were utilized. Immediately after collection, four equal groups of semen sample were made. Group I was kept as control and diluted with Tris upto concentration of 60×106 sperm/ml, where as Groups II, III, and IV were treated with CLC at 3 mg/120× 106 spermatozoa, incubated at 37°C for action of CLC for 10, 15 and 20 min, respectively, and diluted with tris upto concentration of 60×106 sperm/ml. All groups were subjected to equilibration and freezing. The evaluation of semen samples from all groups was carried out at fresh, pre-freeze and post-thaw stage for progressive motility, viability and hypo-osmotic swelling response (HOS response. Results: At the pre-freeze stage, significantly (p<0.05 higher percentage of progressive motility and viability was observed in treatment groups as compared to control with no significant difference among treatment groups. HOS response was significantly (p<0.05 higher in treatment groups as compared to control at pre-freeze stage. At post-thaw stage, significantly (p<0.05 higher percentage of progressive motility, viability and HOS response was recorded in Group II as compared to control and other treatment groups (III and IV. Group II retained significant post-thaw motility and viability at various post-thaw incubation periods. Conclusion: Incubation period of 10 min for CLC treated buffalo spermatozoa yielded significantly higher results in terms of freezability as compared to incubation for 15 and 20 min.

    Full Text Available The ability of swamp buffaloes to adapt with swamp environment was suggested to be supported bytheir digestive system efficiency. The research was done to obtain scientific explanation about digestiveefficiency of swamp buffalo by identification on kinds and distribution of glycoconjugates in swamp buffaloforestomach. Six male swamp buffaloes aged more than 2.5 year old and had body weight between 300-400kg were used in this study. Samples were obtained from Regency of Banjar slaughter house, SouthKalimantan. Every parts of the forestomach included rumen, reticulum, and omasum was taken andprocessed for microscopic observation with hematoxyline eosin (HE and alcian blue-periodic acid schiff(AB-PAS stainings. Sugar residues of glycoconjugates were localized with lectin histochemistry wheatgerm agglutinin (WGA, ulex europaeus agglutinin (UEA, ricinus communis agglutinin (RCA, concanavalinagglutinin (Con A, and soybean agglutinin (SBA. Every part of swamp buffalo forestomach had kinds ofspecific glycoconjugates with special distribution pattern which were different with other ruminant, andwere suitable for their functions in that part. The existence of D mannose/D glucose glycoconjugates thatwas dominant in forestomach estimated that had important role in supporting fermentative digestionfunction in swamp buffalo, through its function as receptor bacteria attachment. This is suggested as aspecial characteristic in digestive system of swamp buffalo which causes high digestive efficiency inswamp buffalo.

    Full Text Available This study evaluated the effect of melatonin supplementation of in vitro maturation media on in vitro maturation (IVM and in vitro fertilization (IVF rate of buffalo oocytes. Cumulus oocytes complexes (COCs were aspirated from follicles of 2-8 mm diameter. In experiment I, COCs were matured in IVM medium supplemented with 0 (control, 250, 500, and 1000 μM melatonin for 22-24 hours in CO2 incubator at 38.5°C with 5% CO2 and at 95% relative humidity. The maturation rate did not differ in media supplemented with melatonin at 250 μM, 500 μM, 1000 μM and control (0 μM. In experiment II, the matured oocytes were fertilized in 50 μl droplets of Tyrode’s Albumin Lactate Pyruvate (TALP medium having 10 ug/ml heparin for sperm (2 million/ml capacitation. The fertilization droplets were then kept for incubation at 5% CO2, 39°C and at 95% relative humidity for 18 hours. The fertilization rate was assessed by sperm penetration and pronuclear formation. Fertilization rate was improved when maturation medium was supplemented with 250 μM melatonin compared to control. In conclusion, melatonin supplementation to serum free maturation media at 250 μM improved the fertilization rate of buffalo oocytes.

    Fifty non-pregnant Surti buffalo heifers aged between 17 and 42 months ( n=24, 24 months) were randomly assigned to groups subject to either natural daylight +4h supplemental light ( n=25) or natural day light ( n=25), to study changes in growth, serum prolactin (Prl), progesterone (P4) and luteinizing hormone (LH) to supplemental lighting. Ambient temperatures (T) and relative humidity (RH) generally were >27° C and <70% during the day-time, respectively. Light-supplemented heifers had 16.2 kg net body weight (BW) gain at 9 weeks compared to 20.8 kg for controls, but higher mean Prl after 6.5 weeks ( P<0.01), and higher P4 (0.41 vs 0.19 ng/ml; P<0.06) than control heifers. Older heifers had 39.7% greater BW ( P<0.01), but a net 4.3% BW gain compared to a 10.1% gain for younger heifers at 10 weeks. Older, light-supplemented heifers had higher mean P4 (0.63 vs 0.19 ng/ml; P<0.07) than the other groups. These weight and hormonal changes suggest that 4 h supplemental light can alter growth and endocrine function in buffaloes under similar planes of nutrition. While light supplementation did not have a positive effect on body wieght during the 10 week study, body weight and endocrine changes due to supplemental light may be important factors for initiation of reproductive cyclicity.

    Full Text Available Sperm mitochondrial activity is investigated and used as “in vitro” spermatozoa vitality indicator and about quality effectiveness of different sperm diluents. It was studied the cytochemically activity of NADPH-diaphorase and LDH-C4 in cryopreserved buffalo sperm. Low intensity of the enzyme reaction was established in all examined sperm samples in both enzymes, regardless from the used cryoprotectors. The main part of the enzyme reaction was localized in mitochondrial sheath and in a very small degree in the head base of spermatozoa. No increase of the enzymes activities or the spermatozoa motility has been found after the incubating with Sp-TALP medium although the established caffeine stimulating effect on the glycolysis and fresh spermatozoa motility. Established by us low sperm motility after cryopreservation may be due to low LDH and NADPH-diaphorase activity due to glycolisis disturbances and ATP synthesis. This method allows to estimate quality of buffalo semen and to find some different disturbances in mitochondrial sheath, which could not be found by routine morphological studies and could be used in practice ejaculates with high number of metabolic active sperm cells.

    The unique components of colostrum like free oligosaccharides and glycoconjugates are known to offer resistance to enzymatic digestion in the gastrointestinal tract and have the ability to inhibit the localized adherence of enteropathogens to the digestive tract of the neonates. In this context, we have evaluated the in vitro effect of buffalo colostrum immunoglobulin G on human pathogen Klebsiella pneumoniae, a predominant multidrug resistant pathogen associated with nasocomial infections. The investigation revealed growth inhibitory potential of immunoglobulin G in a dose dependent manner supported by scanning electron microscopic studies. The N-glycan enriched fraction of immunoglobulin G after PNGase treatment was found more effective, comparable to ampicillin than native immunoglobulin G supporting the fact that colostrum derived oligosaccharides is crucial and act as ideal substrates for undesirable and pathogenic bacteria. The MALDI TOF/TOF analysis confirmed the glycostructures of abundant N-glycans of immunoglobulin G exerting antibacterial activity. The proteomic analysis revealed variations between control and treated cells and expression of chemotaxis-CheY protein (14kDa) was evidenced in response to immunoglobulin G treatment. Hence, it would be interesting to investigate the mode of inhibition of multidrug-resistant K. pneumoniae by buffalo colostrum immunoglobulin G with the identification of a newly expressed signalling protein.

    The pharmacokinetics and dosage regimen of cefotaxime following its single subcutaneous administration (10 mg/kg) were investigated in buffalo calves. Plasma and urine samples were collected over 10 and 24 h post administration, respectively. Cefotaxime in plasma and urine was estimated by microbiological assay technique using E. coli as test organism. The pharmacokinetic profiles fitted one-compartment open model. The peak plasma levels of cefotaxime were 6.48 +/- 0.52 microgram/ml at 30 min and the drug was detected upto 10 h. The absorption half-life and elimination halflife were 0.173 +/- 0.033 h and 1.77 +/- 0.02 h, respectively. The apparent volume of distribution and total body clearance were 1.17 +/- 0.10 l/kg and 0.45 +/- 0.03 l/kg/h, respectively. The urinary excretion of cefotaxime in 24 h, was 5.36 +/- 1.19 percent of total administrated dose. A satisfactory subcutaneous dosage regimen for cefotaxime in buffalo calves would be 13 mg/kg repeated at 12 h intervals.

    Somatic cells in milk are a potential source of nuclei for nuclear transfer to produce genetically identical animals; this is especially important in animals that are susceptible to risks of bacterial infection on biopsy collection. In this study, a minimum of 10 milk samples were collected from each of the three buffaloes representing Murrah breed. All the samples were processed immediately and cell colonies were obtained. Cell colonies from one buffalo (MU-442) survived beyond 10 passages and were evaluated by fluorescence microscopy and used in nuclear transfer experiments. In culture, these cells expressed vimentin, indicating they were of fibroblast origin similar to ear cells. We compared the effectiveness of cloning using those milk-derived fibroblast (MDF) cells and fibroblast cells derived from the ear derived fibroblast (EDF). Fusion and cleavage rates of MDF-NT and EDF-NT embryos were found to be similar (92.43 ± 1.28% vs 94.98 ± 1.24%, and 80.27 ± 1.75% vs 84.56 ± 3.73%, respectively; p > 0.01); however, development to blastocyst stage and total cell number was higher for EDF-NT embryos (50.24 ± 2.54%, 227.14 ± 13.04, respectively, p somatic cells from milk can be cultured effectively and used as nucleus donor to produce cloned blastocyst-stage embryos.

    2014-09-01

    Full Text Available Aim: The experiment was conducted to study the total seminal plasma protein (TSPP and heparin-binding proteins (HBPs in relation to initial semen quality of buffalo bull. Materials and Methods: Semen from two Murrah buffalo bulls (bull no. 605 and 790 with mass motility of ≥3+ were used for the study and categorized into three groups (Group I- Mass motility 3+, Group II- Mass motility 4+ and Group III- Mass motility 5+. Seminal plasma from semen was separated by centrifugation. HBPs was isolated and purified from heparin-agarose affinity column by modified elution buffer. TSPP and isolated HBPs concentration was estimated by Lowry’s method. The purified HBPs were resolved on Sodium dodecyl sulfate polyacrylamide gel electrophoresis to check the protein profile of two bulls. Results: The mean values of TSPP concentrations in bull no. 605 and 790 in Group I, II and III were 30.64±0.12, 31.66±0.09, 32.53±0.19 and 28.51±0.09, 29.49±0.15, 30.45±0.17 mg/mL, respectively. The mean values of HBPs concentrations in bull no. 605 and 790 in Group I, II and III were 3.11±0.07, 3.32±0.06, 3.46±0.08 and 2.51±0.08, 2.91±0.05, 3.10±0.03 mg/mL, respectively. Both the values of TSPP and HBPs were significantly higher (p<0.01 in bull no. 605 when compared to 790 in all the three groups. 31 kDa HBP was more intensely present in bull no. 605, thus may indicate its superiority over bull no. 790 in relation to fertility potential. Conclusion: TSPP and HBPs shows variation in concentration with respect to initial semen quality. Furthermore, presence of fertility related 31 kDa HBPs in one of the bull may be an indication of high fertility of a bull. In future, in-vivo and in-vitro correlative study on larger basis is needed for the establishment of fertility-related HBPs in semen which might establish criteria for selection of buffalo bull with high fertility potential.

    2011-03-01

    Full Text Available In buffalo the overall in vitro embryo production efficiency is lower than cattle, mainly due to the lower cleavage rate (Gasparrini, 2002. In fact in our experience, comparable embryo yields are obtained in the two species only in relation to the cleaved oocytes. It is thought that a major limiting factor is the quality of the frozen semen. It has been demonstrated that freezing results in acrosomal damage, leakage of enzymes, alterations in ionic strength and pH, complete withdrawal of the hydration shell of protein in the solution and loss of motility (Meur et al., 1988. On the other hand we cannot role out that the lower cleavage rate is related to the failure in the accomplishment of oocyte competence after maturation. In fact although nuclear maturation is successfully achieved in our current system.................

    The objective of this study was to investigate the pharmacokinetics of marbofloxacin (MAR) following intravenous (iv) and intramuscular (im) administration of a 2.0 mg/kg body weight dosage to five healthy Egyptian buffalo steers. A cross-over design was used with a washout period of 2 weeks. Blood samples were obtained at 0, 5,10,15, and 20 min and at 0.5,0.75,1,2,4,6,8,10,12,24,30 and 48 hours after marbofloxacin administration. The serum marbofloxacin concentrations were quantitated using a modified agar diffusion bioassay method. Marbofloxacin exhibited a relatively high volume of distribution at steady-state (Vdss = 1.77 Lkg), which suggests good tissue penetration, and a total body clearance (Cltot) of 0.18 L/kgxh,which is associated with a long elimination half-life (tl/2beta = 7.52 h). Marbofloxacin was rapidly absorbed at a dosage of 2.0 mg/kg after im administration with an observed maximum serum concentration (Cmax) value of 2.004 microg/mL obtained at a time to peak concentration (tmax) of 0.5 h, and an absolute bioavailability (F %) of 86.79 +/- 5.53 %. The protein-binding ranged from 22 to 24.6 % with an average of 23.4 %. In conclusion, single iv and im administered doses of marbofloxacin were well tolerated by Egyptian buffalo steers. A dosage of 2 mg/kg body weight might not be enough to treat infections caused by bacteria with minimum inhibitory concentration (MIC) at or above 0.2 microg/mL, based on the calculated area under the inhibitory concentration (AUIC).

    Full Text Available Aim: The present study was aimed at elucidating the distribution of various enzymes in the submandibular salivary gland of buffalo during prenatal development and correlation of these enzyme systems with the secretory activity of the gland. Materials and Methods: The study was carried out on submandibular salivary gland of 15 buffalo fetuses ranging from 11 cm curved crown-rump length (CVRL (78 days to 100 cm CVRL (full term. The fetuses were categorized into three groups based on their CVRL. Results: A weak activity of phosphatases and oxidoreductases was observed in the acinar cells and ductular epithelium at 11-19 cm CVRL (78-114 days. From 28 to 37 cm CVRL (136-157 days, a weak to moderate diffused granular alkaline phosphatase (AKPase activity was observed in the seromucous acini whereas oxidoreductases showed moderate activity. The enzyme activity showed progressively increased with the advancement of the gestation period. The AKPase activity was more in the lumen of acini and along the intercellular canaliculi at 42-100 cm of CVRL (168 days - full term. Large ducts exhibited strong activity for oxidoreductases indicating increased metabolic activity of the cells. Conclusion: The fetuses of Group I showed a uniform weak activity in the acinar cells and ductular epithelium of the gland. In Group II, the enzymes showed a weak to moderate activity which progressively increased with the advancement of gestation period. The enzymes related to Group III showed a strong positive activity for enzymes which reflected higher secretory activity of the gland.

    Full Text Available Aim: The present study was aimed to elucidate ultrastructural changes in the development of sublingual salivary gland of buffalo during prenatal life. Materials and Methods: The study was carried out on sublingual salivary gland of 36 buffalo fetuses ranging from 13.2 cm curved crown-rump length (CVRL (88th day to full term. The fetuses were categorized into three groups based on their CVRL. Results: The cells lining the terminal tubules were undifferentiated with poorly developed cytoplasmic organelles but lacked secretory granules (SGs at 13.2 cm CVRL (88th day. The SGs appeared first in the form of membrane-bound secretory vesicles with homogeneous electron-dense as well as electron-lucent contents at 21.2 cm CVRL (122nd day; however, mucous acinar cells contained electron-lucent granules, while serous secretory cells as well as serous demilunes showed electron-dense granules at 34 cm CVRL (150th day of prenatal life. At 53.5 cm CVRL (194th day, both mucous and serous acini were differentiated by the density of SGs. Conclusion: The cytoplasm of acinar cells was filled with mitochondria, rough endoplasmic reticulum, and Golgi profiles in mid and late fetal age groups. The SGs were increased in number during the late fetal age group. The myoepithelial cells (MECs were located at the base of the acinar cells as well as intercalated and striated ducts and were stellate in shape. The ultrastructure of MEC revealed a parallel stream of myofilaments in the cytoplasm and its processes. The mucous cells were predominantly present in the sublingual salivary gland and were pyramidal in shape.

    2010-02-01

    Full Text Available The fluorescence polarisation assay (FPA was evaluated for the serological diagnosis of bovine brucellosis in buffalo (Bubalus Bubalis in southern Italy. This assay uses O-polysaccharide prepared from Brucella Abortus lipopolysaccharide conjugated with fluorescein isothiocyanate as a tracer. It has many methodological advantages over older, more established tests and can be performed in short time. To measure the fluorescence polarization, a Tecan GENios Pro (Prionics fluorescence-polarization analyzer was used with the procedure described by Nielsen et al. 1996. A cut-off value of 117 millipolarization (mP units was used for testing 912 buffalo sera from Campania Region (526 positive sera and 386 negative sera according to the complement fixation test; CFT. All samples were tested with the Rose Bengal plate (RB. Sensitivity and specificity (Sn for RB were 84.0% and 87.8% and for FPA were 92.6% and 88.9 percent. The FPA gave a kappa coefficient of agreement with respect to CFT of 0.755, while RB (relative to the CFT gave coefficients of 0,715. Finally, ROC analysis suggested a cut-off value which did not agree with the one recommended in the test procedure for cow.

    In developing countries, livestock are often fed a high-lignin, low-nutrient diet that is rich in aromatic compounds. It is therefore important to understand the structure of the microbial community responsible for the metabolism of these substances. A metagenomic analysis was therefore carried out to assess the microbial communities associated with the liquid and solid fractions of rumen biomaterial from domestic Mehsani buffalo (Bubalus bubalis) fed with varying proportions of roughage. The experimental design consisted of three feeding regimes (50, 75 and 100 % roughage) and two roughage types (green and dry). Genes associated with aromatic compound degradation were assessed via high-throughput DNA sequencing. A total of 3914.94 Mb data were generated from all treatment groups. Genes coding for functional responses associated with aromatic compound metabolism were more prevalent in the liquid fraction of rumen samples than solid fractions. Statistically significant differences (p aromatic compound catabolism. At the phylum level, Bacteroidetes were dominant in all treatments closely followed by the Firmicutes. This study demonstrates the use of feed type to selectively enrich microbial communities capable of metabolizing aromatic compounds in the rumen of domestic buffalo. The results may help to improve nutrient utilization efficiency in livestock and are thus of interest to farming industries, particularly in developing countries, worldwide.

    Full Text Available This paper aimed to evaluate the surface temperatures of buffalo bulls using infrared thermography, considering four distinct anatomical parts over time, and to correlate surface temperatures and thermal comfort indexes. The humid tropical climate (Köppen's Afi was predominant in the research station where the experiment was performed and the trial lasted from April to August. Ten bulls (n=10 were evaluated every 25 days (morning: 6:00-9:00; afternoon: 12:00-15:00 and the parameters assessed were respiratory rate (RR, rectal temperature (RT, and the thermograms of surface temperature for orbital area (ORB, right flank (RF, left flank (LF and scrotum (SCR. Climatological data was continuously monitored and the Temperature and Humidity Index (THI and the Index of Comfort of Benezra (ICB were calculated. The average values of THI were ≥78, and significant differences between shifts were observed (P<0.05. The ICB ranged from 1.96 to 2.25 and significant differences were observed for shifts and throughout the months (P<0.05. The averages of surface temperatures were RT=38.2±0.5°C, ORB=36.1±0.8°C, LF=33.5±2.5°C, RF=35.4±1.7ºC and SCR=33.3±1.1°C, which exhibited significant differences for shifts and throughout the months (P<0.05. Positive correlations were obtained between THI and ORB (0.72, RF (0.77, LF (0.75 and SCR (0.41 (P<0.0001. The maximum temperature of ORB showed the highest correlation with RT (0.58, P<0.0001. Therefore, the surface temperatures are subject to climatic variations and increase throughout the day, due to the variation in thermal comfort indexes, and the maximum ORB temperature was the parameter most related to rectal temperature. Lastly, the results indicate that IRT may be a useful non-invasive and accurate tool to detect the variations in ORB, LF, RF and SCR temperature in buffalo bulls.

    Full Text Available Aim: The aim of this study was to investigate the effect of commercial egg yolk powder as an alternative to fresh egg yolk on freezability of Murrah buffalo semen. Materials and Methods: Semen samples (12 from 3 Murrah buffaloes (4 from each bull with mass motility (≥3+ and total motility (70% and above were utilized in this study. Immediately after collection, each sample was divided into four groups. Groups I was diluted up to 60×106 sperm/ml with tris extender containing 10% fresh egg yolk and Groups II, III, and IV were diluted up to 60×106 sperm/ml with tris extender containing 2%, 4%, and 6% egg yolk powder, respectively. Semen samples were processed and cryopreserved followed by examination of frozen semen samples after 24 h. Semen samples from each group were evaluated for total motility, viability, acrosomal integrity, abnormality, and hypo-osmotic swelling test (HOST response after dilution, pre-freeze, and post-thaw stage. Results: Pre-freeze total motility was significantly (p<0.05 higher in Groups III and IV as compared to Groups I and II, and post-thaw total motility was significantly (p<0.01 higher in Group III as compared to other three groups. Viability was significantly (p<0.05 higher in Groups II, III, and IV than Group I at the pre-freeze stage. Significantly (p<0.01 higher viability and acrosomal integrity were recorded in Group III as compared to other three groups at the post-thaw stage. Abnormality was significantly (p<0.05 higher in Group IV than other three groups. HOST response was significantly (p<0.05 higher in Groups II and III than Groups I and IV at the pre-freeze and post-thaw stages. Conclusion: Addition of egg yolk powder at 4% level yielded significantly better results in terms of post-thaw semen quality as compared to the fresh egg yolk and other concentrations of egg yolk powder (2% and 6%.

    Full Text Available In vitro embryo production (IVEP is largely applied world wide to animal breeding. One of the principal steps of the IVEP is represented by embryo culture (Khurana and Niemann., 2000. In the past, embryos were grown in co-culture systems with other cells such as oviductal epithelial cells, cumulus cells, Buffalo rat liver (BRL and VERO cells (Duszewska et al., 2000. These cells are able to supply the nutrients for embryo development by their replication and metabolism. Nevertheless, the metabolic activity of these cells is also responsible of an early lowering of pH in the culture medium: that needs to be changed every two days. Furthermore, with this culture system it is impossible to standardize all the procedure: in fact the result is dependent from several variables, as the quality of the cells and their concentration in co-culture. The use of defined culture media is necessary to acquire a better comprehension of metabolism and biochemical requirements for IVEP........

    During a survey in a dairy plant in Italy, the second strain (strain FG 206) of Arcobacter suis described in the literature was isolated from raw water buffalo milk. The objective of this study was to confirm the species identification, better define the species by comparing its characteristics with those of the reference strain (F41(T) = CECT 7833(T) = LMG 26152(T)) and to investigate its potential clinical relevance by detecting the virulence gene pattern of the new strain. Phenotypical characterization and 16S rRNA-RFLP gave a complete overlap of results for the two strains. As expected, an RFLP pattern common to A. suis and Arcobacter defluvii was obtained by MseI endonuclease digestion, and a pattern specific for A. suis was obtained by BfaI endonuclease digestion. 16S rRNA sequencing and multilocus phylogenetic analysis (MLPA) showed a robust relatedness of strain FG 206 to the A. suis type strain F41(T). The recovery of strain FG 206 from a dairy plant shows that this species of Arcobacter is present in the food chain. Like the type strain recovered from pig meat, the species A. suis may not be confined to a single type of food.

Sera from cattle (n = 216) and water buffaloes (n = 133) collected from five different provinces of Egypt (Behera, Alexandria, Assuit, Gharbia, and Matrouh) were analyzed. Testing for B. besnoiti antibodies by PrioCHECK® Besnoitia Ab 2.0 ELISA initially identified 13.75 % (48 out of 349) of individual sera as positive at the manufacturer's suggested cutoff threshold, 15 percent positivity (PP). Statistically significant associations between B. besnoiti prevalence, species, sex, age, and geographical distribution were observed. Seropositive animals were distributed in all of the provinces from which animals were sampled except Gharbia province. Assuit province showed the highest percentage of infection (30.76 %) followed by Matrouh, Alexandria, and Behera provinces (25, 16.29, and 9.6 %, respectively). The highest infection rate of B. besnoiti was significantly higher in cattle (17.13 %) than in water buffaloes (9.02 %). Positive cases were observed in all age categories. While the highest infection rate (17.13 %) was recorded in the age group 5-10 years followed by the age group 1-5 years (15.38 %), and only one positive case (1.58 %) was recorded in the age group less than 1 year. The highest infection rate of B. besnoiti infection was recorded in the female animals (14.95 %) followed by the male animals (8.33). This is the first report on the detection of B. besnoiti in cattle and water buffaloes in Egypt.

    Objective: To assess normal conjunctival cytological and bacteriological/fungal flora features in the Mediterranean buffalo(Bubalus bubalis).Methods: Swabs were taken from the inferior conjunctival sac of both eyes of 57 healthy female buffaloes aged 24–36 months, with no evidence of ocular disease, farmed in Campania region(Southern Italy), for microbiological analysis. Conjunctival eye specimens of both eyes were subsequently obtained by a cyto-brush, for cytological analysis.The antimicrobial susceptibility of bacterial isolates was also determined using the diskdiffusion method on Mueller Hinton agar plates.Results: Cytological examination of conjunctival swab specimens(114 eyes) revealed epithelial cells(basal, intermediate, columnar and super ficial) in all samples, whereas neutrophils, lymphocytes and plasma cells were present in 70%, 10% and 2% of samples,respectively. Microorganisms, for a total of 261 aerobic bacteria and 6 fungi, were isolated from 112/114 conjunctival samples [98.25%; 95% con fidence interval(CI): 93.18–99.70]. Only two conjunctival swabs did not yield bacteria and/or fungi(2/114, 1.75%;95% CI: 0.30–6.82). Gram-positive aerobes were most commonly cultured(181/261,69.35%; 95% CI: 63.31–74.81), with Enterococcus faecium and Staphylococcus lentus predominating. Escherichia coli was the most frequently isolated as Gram-negative bacteria(80/261, 30.65%; 95% CI: 25.19–36.69). The antimicrobial resistance patterns of the isolated bacteria showed amoxycillin/clavulanic acid and cephalothin as the least sensitive antibiotics for both Gram-positive and Gram-negative bacteria.Conclusions: These results provided first information on normal conjunctival ocular micro flora and cytological features in Mediterranean buffalo.

    Full Text Available Buffalo is an important livestock resource, with a great participation in agricultural systems, providing milk, meat, and work power. Umbilical cord is responsible for maternal-fetal nutrients exchange during pregnancy, and its alterations can compromise the fetal development. We investigated ten pregnant uteruses collected from cross-bread buffaloes in different stages of gestation. Pregnancy and fetal age was determined by measuring the apex sacral length and development period was calculated by previously published formula. Umbilical cords were measured for length determination. Umbilical cord vascular net and anastomosis were observed by injection of Neoprene latex. Histological sections of the umbilical cord were studied after stain with HE, picrossirius, toluidine blue, orceine, and PAS reaction. Buffaloes' umbilical cord was formed by two central arteries, an allantois duct and two peripheral veins. The artery wall was composed by large quantity of collagen, elastic fibers, fibroblasts and large number of vasa vasorum. The allantois duct was located between the arteries and presented a great number of small nourishing vessels. Small nourishing vessels should be carefully considered to avoid to be mistaken to the arterials and veins vasa vasorum. Medium length of umbilical cord from buffalos was 11.8cm (minimum of 6.8cm and maximum of 17.4cm.Búfalo é uma importante fonte de recurso nos rebanhos animais, apresentando uma grande participação na agropecuária, provendo leite, carne e força de trabalho.

    subsp. paratuberculosis (MAP. No record on the occurrence of paratuberculosis in buffaloes in Brazil could be found. Five of 100 buffaloes in a herd in Pernambuco-Brazil showed clinical signs characteristic of PTB. At necropsy, of two animals the lesions were restricted to the small intestine with thickening and corrugation of the mucosa, increase of mesenteric lymph nodes and prominent lymph vessels. Histopathology revealed granulomatous inflammation infiltrated with numerous epithelioid macrophages, Langhans type giant cells, and clusters of Ziehl-Neelsen (ZN positive organisms within the intestinal mucosa. In the mesenteric lymph nodes there was thickening of the capsule and marked granulomatous inflammation. Smears of feces and scrapping smears were prepared from intestinal mucosa and cut surface of mesenteric lymph nodes and, stained by the Ziehl-Neelsen method for research of acid fast bacilli, with positive results. Lymph nodes and intestinal mucosa revealed at IS900 specific polymerase chain reaction amplification of a fragment of about 110pb, confirmed by the comparison with other sequences of M. avium subsp. paratuberculosis available in GenBank.

In the second step, semen samples were diluted with tris-egg yolk-glycerol extender containing the same amounts of sodium selenite, cooled to 4 ˚C, equilibrated and semen parameters (motility, viability, membrane integrity and DNA damage were estimated. Then, the semen was packed in 0.5 mL French straws and frozen in liquid nitrogen. Later, the semen was thawed and analyzed for the same parameters, as well as total antioxidant capacity. Results showed that addition of 1 and 2 μgmL-1 selenium to the semen extender significantly increased the sperm motility of fresh and equilibrated semen compared to the control without affecting other parameters. However, in frozen-thawed semen, extenders containing 1 and 2 μg mL-1 selenium significantly improved sperm motility, viability, membrane integrity and semen total antioxidant capacity and also resulted in lower DNA damaged sperms. In this study selenium supplementation of semen extender of 4 and 8 μg mL-1 had deleterious effects on sperm parameters as early as the samples were prepared for freezing.

    The aim of this study was to describe modifications in plasma homocysteine (Hcy), vitamin E (VitE) and malondialdehyde (MDA) concentrations in the first 56 days after artificial insemination (AI) in buffalo. Thirty-five buffalo cows were divided, ex post, into three groups on the basis of pregnancy diagnosis: pregnant, not pregnant, with embryonic mortality. Pregnancy was diagnosed by ultrasonography and plasma concentrations of pregnancy-associated glycoproteins (PAGs). Our results showed that, in pregnant buffaloes, included those with embryonic mortality, MDA increased progressively while VitE decreased. In non-pregnant buffaloes, MDA and Vit E were unchanged. Hcy concentrations also remained unchanged within each group throughout the study period, but were lower in non-pregnant buffaloes than in the pregnant ones and in those with embryonic mortality. In conclusion, present data suggest that successful pregnancy in buffalo cows might be linked to Hcy metabolism and oxidative stress involvement.

    Water buffalo are important draft animals for agriculture in resource-restricted areas worldwide. Water buffalo were shown to be experimentally susceptible to infection with Neospora caninum, potentially affected by neosporosis, and naturally exposed to the parasite in Asia. Although enzootic to Thailand, the distribution of N. caninum among Thai water buffalo is unclear. The objectives of this study were to determine the seroprevalence of N. caninum among water buffalo of northeast Thailand and to identify risk factors associated with their exposure to N. caninum. Sera from 628 water buffalo from 288 farms were tested with an indirect fluorescent antibody test (IFAT). A total of 57 samples from 48 herds contained antibodies to N. caninum, indicating overall seroprevalence of 9.1% and 16.7% among individual animals and herds, respectively. The overall seroprevalence was highest in provinces located in the Khorat Basin in the southern part of the region tested. Host age was also associated with seroprevalence, with the greatest seroprevalence (16.1%) among buffalo over 10 years of age, followed by 5-10 years of age (13.4%), 3-5 years (9.2%), and less than 3 years (1.2%). These results collectively suggested that horizontal transmission from canine definitive hosts was an important route of water buffalo exposure to N. caninum. These results also verified the importance of risk factor analysis for effective bovine neosporosis control strategies at the local level.

    Full Text Available The aim of this study was to compare serum hormone profiles (progesterone and estradiol-17β in buffaloes with dystocia and unassisted calving in three agro-ecological zones of Punjab, Pakistan. One hundred and seventy three buffaloes (n=173 with assisted (dystocia and unassisted calving (normal birth were sampled for study. The results showed that the buffaloes suffering with dystocia had significantly higher (P<0.05 mean serum progesterone level compared with those having normal calving. The comparison amongst the agro-ecological zones revealed that serum progesterone level of dystocia cases in buffaloes of northern irrigated zone was significantly lower (P<0.05 compared with those in the southern irrigated zone and the arid zone, whereas the latter two did not differ between each other. No difference was observed in serum progesterone levels in normal buffaloes when compared amongst three agro-ecological zones. The serum estradiol-17β profile showed a significant (P<0.05 lower level in buffaloes with dystocia as compared to those with normal calving. Mean serum estradiol-17β level in the buffaloes affected with dystocia in the northern irrigated zone was significantly lower (P<0.05 compared to those in the southern irrigated zone and the arid zone wherein the latter two did not differ between each other.

    Full Text Available Aim: To evaluate the follicular dynamics, superovulatory response, and embryo recovery following superstimulatory treatment initiated at estradiol-17β induced follicular wave emergence and its comparison with conventional superstimulatory protocol in buffaloes. Materials and Methods: Six normal cycling pluriparous buffaloes, lactating, 90-180 days post-partum, and weighing between 500 and 660 kg were superstimulated twice with a withdrawal period of 35 days in between two treatments. In superstimulation protocol-1 (estradiol group buffaloes were administered estradiol-17β (2 mg, i.m. and eazibreed controlled internal drug release (CIDR was inserted intravaginally (day=0 at the random stage of the estrous cycle. On the day 4, buffaloes were superstimulated using follicle stimulating hormone (FSH 400 mg, divided into 10 tapering doses given at 12 hourly intervals. Prostaglandin F2α analogs (PGF2α was administered at day 7.5 and day 8, and CIDR was removed with the second PGF2α injection. In superstimulation protocol - 2 (conventional group buffaloes were superstimulated on the 10th day of the estrous cycle with same FSH dose regimen and similar timings for PGF2α injections. In both groups, half of the buffaloes were treated with luteinizing hormone (LH 25 mg and other half with 100 ug buserelin; gonadotrophin releasing hormone (GnRH analog at 12 h after the end of FSH treatment. All buffaloes in both protocols were inseminated twice at 12 and 24 h of LH/GnRH treatment. Daily ultrasonography was performed to record the size and number of follicles and superovulatory response. Results: Significantly higher number of small follicles (8 mm, corpora lutea, and transferable embryos was higher in buffaloes superstimulated at estradiol-induced follicular wave compared to the conventional protocol: Further the percentage of transferable embryos was significantly higher in buffaloes administered with LH compared to GnRH.

    The aim of this study was to compare seven non-linear mathematical models (Brody, Wood, Dhanoa, Sikka, Nelder, Rook and Dijkstra) to examine their efficiency in describing the lactation curves for milk fat to protein ratio (FPR) in Iranian buffaloes. Data were 43 818 test-day records for FPR from the first three lactations of Iranian buffaloes which were collected on 523 dairy herds in the period from 1996 to 2012 by the Animal Breeding Center of Iran. Each model was fitted to monthly FPR records of buffaloes using the non-linear mixed model procedure (PROC NLMIXED) in SAS and the parameters were estimated. The models were tested for goodness of fit using Akaike's information criterion (AIC), Bayesian information criterion (BIC) and log maximum likelihood (-2 Log L). The Nelder and Sikka mixed models provided the best fit of lactation curve for FPR in the first and second lactations of Iranian buffaloes, respectively. However, Wood, Dhanoa and Sikka mixed models provided the best fit of lactation curve for FPR in the third parity buffaloes. Evaluation of first, second and third lactation features showed that all models, except for Dijkstra model in the third lactation, under-predicted test time at which daily FPR was minimum. On the other hand, minimum FPR was over-predicted by all equations. Evaluation of the different models used in this study indicated that non-linear mixed models were sufficient for fitting test-day FPR records of Iranian buffaloes.

    Objective:To investigate changes in follicular fluid concentrations of reactive oxygen species (ROS) and total antioxidant capacity(TAC) and degree of oxidative damage to follicular cells, using protein carbonyl(PC) as marker of oxidative stress, were investigated during reproductive acyclicity in buffalo.Methods:Follicular fluid was aspirated from follicles grouped into three classes depending upon their diameter [small(5.0-7.0 mm), medium(7.1-10.0 mm), and large (>10.0 mm)].Progesterone and estradiol were estimated to determine functional status(P:E ratio) of the follicles.Results:Acyclic buffaloes had greater concentrations ofROS(P<0.001) andPC (P=0.0412) and lower concentrations ofTAC(P=0.0280) than cyclic buffaloes.An interesting novel finding was the complete absence of lowP:E functionally active follicles in acyclic buffaloes. Results indicated a pronounced follicular fluid oxidant-antioxidant imbalance and oxidative damage to follicular cells during acyclicity in buffalo.Conclusion:In conclusion, this study provided evidence about role of oxidative stress in pathogenesis of reproductive acyclicity.

    The development of new molecular techniques (array CGH, M-FISH, SKY-FISH, etc.) has led to great advancements in the entire field of molecular cytogenetics. However, the application of these methods is still very limited in farm animals. In the present study, we report, for the first time, the production of 13 river buffalo (Bubalus bubalis, 2n = 50) chromosome-specific painting probes, generated via chromosome microdissection and the DOP-PCR procedure. A sequential multicolor-FISH approach is also proposed on the same slide for the rapid identification of river buffalo chromosome/arms, namely, 1p-1q, 2p-2q, 3p-3q, 4p-4q, 5p-5q, 18, X, and Y, using both conventional and late-replicating banded chromosome preparations counterstained by DAPI. The provided 'bank' of chromosome-specific painting probes is useful for any further cytogenetic investigation not only for the buffalo breeds, but also for other species of the family Bovidae, such as cattle, sheep, and goats, for chromosome abnormality diagnosis, and, more generally, for evolutionary studies.

    We report an extended river buffalo (Bubalus bubalis, 2n = 50; BBU) cytogenetic map including 388 loci, of which 68 have been FISH-mapped on autosomes in the present study. Ovine and caprine BAC clones containing both type I loci (known genes) and type II loci (simple sequence repeats (SRs), microsatellite marker, sequence-tagged sites (STSs)), previously assigned to sheep chromosomes, have been localized on R-banded river buffalo chromosomes (BBU), which expands the cytogenetic map of this important domestic species and increases our knowledge of the physical organization of its genome. The loci mapped in the present study correspond to loci already localized on homoeologous cattle (and sheep) chromosomes and chromosome bands, further confirming the high degree of chromosome homoeologies among bovids. The comparison of the integrated cytogenetic maps of BBU2p/BBU10 and BBU5p/BBU16 with those of human chromosomes (HSA) 6 and 11, respectively, identified, at least, nine conserved chromosome segments in each case and complex rearrangements differentiating river buffalo (and cattle) and human chromosomes.

    Previous studies suggested a close relationship between ruminant gut microbes and the mammary gland. In this study, shotgun metagenomic sequencing was used to reveal the differences in the intestinal microbiome potentially related to milk components in Murrah buffaloes and Chinese Holstein cattle. A PCoA based on the weighted Unifrac distances showed an apparent clustering pattern in the structure of intestinal microbiota between buffalo and cattle. We could attribute the structural difference to the genera of Sutterella, Coprococcus and Dorea. A further analysis of microbial functional features revealed that the biosynthesis of amino acids (including lysine, valine, leucine and isoleucine), lipopolysaccharide biosynthesis and cofactor/vitamin biosynthesis were enriched in the buffalo. In contrast, dairy cattle had higher levels of pyruvate metabolism and carbon fixation in photosynthetic organisms. A further correlation analysis based on different milk components and the typical microbiome uncovered a significant positive correlation between milk protein and the microbial biosynthesis of amino acids, which was also positively correlated in the genera of Parabacteroides, Dorea and Sutterella. This study will expand our understanding of the intestinal microbiome of buffalo and cattle as representative ruminants, as well as provide new views about how to improve the production and nutritional qualities of animal milk.

    Full Text Available Abstract Background Malignant catarrhal fever (MCF is a fatal herpesvirus infection, affecting various wild and domestic ruminants all over the world. Water buffaloes were reported to be particularly susceptible for the ovine herpesvirus-2 (OvHV-2 causing the sheep-associated form of MCF (SA-MCF. This report describes the first case of possibly caprine-associated malignant catarrhal fever symptoms in a domestic water buffalo in Switzerland. Case presentation The buffalo cow presented with persistent fever, dyspnoea, nasal bleeding and haematuria. Despite symptomatic therapy, the buffalo died and was submitted to post mortem examination. Major findings were an abomasal ulceration, a mild haemorrhagic cystitis and multifocal haemorrhages on the epicardium and on serosal and mucosal surfaces. Eyes and oral cavity were not affected. Histopathology revealed a mild to moderate lymphohistiocytic vasculitis limited to the brain and the urinary bladder. Although these findings are typical for MCF, OvHV-2 DNA was not detected in peripheral blood lymphocytes or in paraffin-embedded brain, using an OvHV-2 specific real time PCR. With the aid of a panherpesvirus PCR, a caprine herpesvirus-2 (CpHV-2 sequence could be amplified from both samples. Conclusions To our knowledge, this is the first report of malignant catarrhal fever in the subfamily Bovinae, where the presence of CpHV-2 could be demonstrated. The etiological context has yet to be evaluated.

    Full Text Available Forty clinically healthy buffaloes of either sex were divided into two age-groups of equal size i.e., young (12-42 months and adult (48-96 months. Histological sections were prepared by routine method and stained by H&E. AutoCAD® image analysis software and ocular micrometer were used for the morphometric evaluations. Studies revealed that the adrenal cortex of buffalo was divided into four zones, zona glomerulosa, zona intermedia, zona fasciculate and zona reticularis. The zona fasciculata was recorded as the widest and zona reticularis narrowest zone of the adrenal cortex. The volume of cardiomyocytic nuclei (μm3, volume of renal corpuscles (μm3×103, volume of nuclei of cells of zona glomerulosa (μm3, thickness of the zona glomerulosa, zona intermedia and zona fasciculata of adrenal cortex in adult buffaloes were significantly (P<0.01 higher as compared to their younger counterparts. It is conceivable that the development of blood related parameters showed an increase parallel to the advancing age in order to adjust with the increasing blood pressure due to physiological development process in buffalo.

    This study analysed buffaloes from north-east India and compared their nuclear and mitochondrial DNA variations with buffaloes of mainland India, China, Mediterranean and South-East Asia. Microsatellite genotypes of 338 buffaloes including 210 from six north-east Indian buffalo populations and three mainland Indian breeds were analysed to evaluate their genetic structure and evolutionary relationships. Phylogenetic analysis and multidimensional scaling plot of pairwise FST revealed the clustering of all swamp-type buffaloes of north-east India with Lower Assamese (significantly hybrid type) buffaloes in one plane and all the mainland river buffaloes in another plane while the upper Assamese buffaloes being distinct from both these clusters. Analysis of mtDNA D-loop region of 530-bp length was performed on 345 sequences belonging to 23 buffalo populations from various geographical regions to establish the phylogeography of Indian water buffalo. The swamp buffaloes of north-east India clustered with both the lineages of Chinese swamp buffalo. Multidimensional scaling display of pairwise FST derived from mitochondrial DNA data showed clustering of upper Assamese, Chilika and Mediterranean buffaloes distinctly from all the other Indian buffalo populations. Median-joining network analysis further confirmed the distinctness and ancestral nature of these buffaloes. The study revealed north-east region of India forming part of the wider hybrid zone of water buffalo that may probably extend from north-east India to South-East Asia.

    Adult stem cells are known for their plasticity and their potential to differentiate into several different cell types; these characteristics have implications for cell therapy and reproductive biotechnologies. In this study, we report on the isolation and characterization of mesenchymal stem cells (MSC) derived from bovine and buffalo adipose tissue. Cells isolated using enzymatic digestion of bovine and buffalo adipose-tissue biopsy samples were grown in vitro for at least 15 passages, verifying their capacity to proliferate. These cells were also subjected to immunophenotypic characterization for the presence of CD90, CD105, and CD79, and the absence of CD45, CD34, and CD73, which are positive and negative markers of MSC, respectively. To prove their multipotency, the cells were induced to differentiate into three different cell types, chondrocytes, osteoblasts, and adipocytes, which were stained with tissue-specific dyes (Chondrogenic-Alcian Blue, Osteogenic-Alizarin Red, and Adipogenic-Oil-Red O, respectively) to confirm differentiation. Gene expression analysis of pluripotency-related genes was also conducted. Our results suggest that adipose tissue from bovines and buffalos can be used as a source of MSC, making adipose tissue-derived cells an interesting option for cell therapy and regenerative medicine. Additionally, these findings have implications for reproductive biotechnology because the use of MSC as nuclear donors has been linked to an increase in the efficiency of nuclear transfer.

    Full Text Available In April 1998 urine samples from adult female buffaloes were collected in a farm located in Registro, Vale do Ribeira, São Paulo State, Brazil. The urine samples obtained after furosemide injection were immediately transported to the laboratory in liquid modified EMJH medium and seeded, by the serial dilution technique, into Fletcher's or modified EMJH-0.2% agar, both of them with 5-fluorouracil 100mg/mL. The intraperitoneoum inoculation of 0.5 mL was also performed with each urine sample in young, adult hamsters (Mesocricetus auratus. All samples seeded directly in culture medium were contaminated. The hamsters did not show any sign of disease and were killed at the 21st post inoculation day. At this time kidney cultures of these animals were performed and from one of them, one leptospira strain (M04-98 was isolated, identified as belonging to serogroup Sejroe by Microscopic Agglutination Test (MAT with a panel of 36 rabbit sera against serovars representative for the pathogenic serogroups. Subsequently, MAT was carried out with antisera against the 19 reference strains of serogroup Sejroe, revealing a close relationship with serovar guaricura. Afterwards the MAT was done with a panel of 18 monoclonal antibodies representative for serovars of serogroup Sejroe. The histogram closely resembled that of serovar guaricura. So Cross Agglutination Absorption Test (CAAT was carried out with the buffalo isolate and serovar guaricura, supporting the relationship between the buffalo isolate and serovar guaricura.

    Full Text Available The present study describes the isolation and characterisation of new PAG molecules extracted from mid- and late-pregnancy placentas in the water buffalo (Bubalis bubalis. After extraction, acid and ammonium sulphate precipitation and DEAE chromatography water buffalo PAG (wbPAG were enriched by Vicia villosa agarose (VVA affininity chromatography. As determined by Western blotting with anti-PAG-sera, apparent molecular masses of immunoreactive bands from VVA peaks ranged from 59.5 to 75.8 kDa and from 57.8 to 80.9 kDa in the mid- and late- pregnancy placenta respectively. Aminoterminal microsequencing of proteins allowed the identification of three distinct wbPAG sequences wich have ben deposed in the SwissProt database: RGSXLTIHPLRNIRDFFYUG (Acc. n. P85048, RGSXLTILPLRNIID (P85049 and RGSXLTHLPLRNI (P85050. Their comparison to those previously identified revealed that two of them were new since they have not been described yet. Our results confirm the suitability of VVA chromatography in enrichment of multiple PAG molecules expressed in buffalo placenta. Productions of specific antisera can be very useful in immonoistochemical and immunocyitochemical studies of PAG expression in fetomaternal interfaces. Purified native PAG are also required for development on specific immoassays (RIA/ELISA currently used for pregnancy diagnosis and physiological investigation in farm animal.

    The present study aims to identify the heat responsive genes and biological pathways in heat stressed buffalo mammary epithelial cells (MECs). The primary mammary epithelial cells of riverine buffalo were exposed to thermal stress at 42°C for one hour. The cells were subsequently allowed to recover at 37°C and harvested at different time intervals (30 min to 48 h) along with control samples (un-stressed). In order to assess the impact of heat stress in buffalo MECs, several in-vitro cellular parameters (lactate dehydrogenase activity, cell proliferation assay, cellular viability, cell death and apoptosis) and transcriptional studies were conducted. The heat stress resulted in overall decrease in cell viability and cell proliferation of MECs while induction of cellular apoptosis and necrosis. The transcriptomic profile of heat stressed MECs was generated using Agilent 44 K bovine oligonucleotide array and at cutoff criteria of ≥3-or ≤3 fold change, a total of 153 genes were observed to be upregulated while 8 genes were down regulated across all time points post heat stress. The genes that were specifically up-regulated or down-regulated were identified as heat responsive genes. The upregulated genes in heat stressed MECs belonged to heat shock family viz., HSPA6, HSPB8, DNAJB2, HSPA1A. Along with HSPs, genes like BOLA, MRPL55, PFKFB3, PSMC2, ENDODD1, ARID5A, and SENP3 were also upregulated. Microarray data revealed that the heat responsive genes belonged to different functional classes viz., chaperons; immune responsive; cell proliferation and metabolism related. Gene ontology analysis revealed enrichment of several biological processes like; cellular process, metabolic process, response to stimulus, biological regulation, immune system processes and signaling. The transcriptome analysis data was further validated by RT-qPCR studies. Several HSP (HSP40, HSP60, HSP70, HSP90, and HSPB1), apoptotic (Bax and Bcl2), immune (IL6, TNFα and NF-kβ) and oxidative

    Haemorrhagic septicaemia (HS) is an acute, fatal, septicaemic disease of cattle and buffaloes caused by one of two specific serotypes of Pasteurella multocida B:2 and E:2 in Asian and African, respectively. It is well known that HS affect mainly the respiratory and digestive tracts. However, involvement of the nervous system in pathogenesis of HS has been reported in previous studies without details. In this study, nine buffalo calves of 8 months old were distributed into three groups. Animals of Group 1 and 2 were inoculated orally and subcutaneously with 10 ml of 1 × 10(12) cfu/ml of P. multocida B:2, respectively, while animals of Group 3 were inoculated orally with 10 ml of phosphate buffer saline as a control. All calves in Group 1 and Group 3 were euthanised after 504 h (21 day) post-infection, while calves in Group 2 had to euthanise after 12 h post-infection as they develop sever clinical signs of HS. Significant differences were found in Group 2 in the mean scores of clinical signs, gross and histopathological changes which mainly affect different anatomic regions of the nervous system. In addition, successful bacterial isolation of P. multocida B:2 were obtained from different sites of the nervous system. On the other hand, less sever, clinical, gross and histopathological changes were found in Group 1. These results provide for the first time strong evidence of involving of the nervous system in pathogenesis of HS, especially in the peracute stage of the disease.

    Full Text Available This paper aimed to study the dynamics of early embryonic development, in terms of redistribution of cytoskeleton (microtubules, actin microfilaments and chromatin configurations during the first cell cycle in swamp buffalo embryos. Oocytes were matured and fertilized in vitro, and they were fixed at various time points after IVF. At 6 h after IVF, 44.4% matured oocytes were penetrated by spermatozoa. Partial ZP digestion, however, did not improve fertilization rate compared to control (P>.05. At 12 h after IVF, the fertilized oocytes progressed to the second meiotic division and formed the female pronucleus simultaneously with the paternal chromatin continued to decondense. A sperm aster was observed radiating from the base of the decondensing sperm head. At 18 h after IVF, most presumptive zygotes had reached the pronuclear stage. The sperm aster was concurrently enlarged to assist the migration and apposition of pronuclei. Cell cleavage was facilitated by microfilaments and firstly observed by 30 h after IVF. In conclusion, the cytoskeleton actively involves with the process of fertilization and cleavage in swamp buffalo oocytes. The centrosomal material is paternally inherited. Fertilization failure is predominantly caused by poor sperm penetration. However, partial digestion of ZP did not improve fertilization rate.

    Four, rumen fistulated swamp buffalo bulls were used to study microbial populations in the rumen when supplemented with coconut oil and mangosteen peel. Animals were randomly assigned to a 4 × 4 Latin square design. Four treatments were un-supplemented (Control), supplementation with coconut oil at 50 g/kg (CO5), supplementation with mangosteen peel at 30 g/kg (MP3) and supplementation with CO5 and MP3 (COM), of total DM intake. Animals received concentrate at 10 g/kg of BW, and rice straw was given ad libitum. Abundance of total bacteria was increased by CO5 supplementation, whereas populations of protozoa and Fibrobacter succinogenes were reduced by CO5 and COM supplementation. Dietary supplementation did not affect methanogen, Ruminococcus flavefaciens or Ruminococcus albus abundances. Dietary treatments changed denaturing gradient gel electrophoresis (DGGE) band patterns of methanogens and protozoa when compared with the control group, especially when supplemented with MP3. Supplementation of COM resulted in the greatest difference in pattern of DGGE bands for total bacteria compared with the control. Coconut oil and mangosteen peel supplementation resulted in changing of rumen microbial abundances and communities; however, combination of them could be more benefit to improve rumen fermentation of swamp buffalo fed on rice straw.

    Full Text Available Aim: The study was conducted to investigate the effect of cholesterol loaded cyclodextrin (CLC on freezability of buffalo spermatozoa. Materials and Methods: Murrah buffalo bull semen samples with progressive motility of 70% and greater were used. After the evaluation of motility and livability, four equal fractions of semen samples were made. Group I was kept as control and diluted with Tris, whereas Group II, III and IV were treated with CLC solution at the rate of 2.0, 3.0 and 4.0 mg/ml respectively to obtain 120 × 106 sperm/ml as final spermatozoa concentration. The aliquots of all the groups were incubated for action of CLC, followed by dilution and freezing. Evaluation at pre-freeze and post-thaw stage of progressive motility, viability and level of cholesterol and phospholipid was done. Results: The mean cholesterol content (μg/100 × 106 spermatozoa of Group I, II, III and IV at pre-freeze stage was 21.55±0.63, 49.56±1.38, 55.67±0.45 and 47.79±1.01 and at post-thaw stage were 13.18±0.45, 34.27±0.71, 36.21±0.48 and 33.68±0.56, respectively. At pre-freeze stage, cholesterol content was significantly (p<0.01 higher in Group III in comparison to other groups. The mean cholesterol and phospholipids content of fresh sperm was 24.14±0.58 and 51.13±0.66 μg/100 × 106 sperm cells, respectively, and C/P ratio of spermatozoa at fresh stage was 0.47±0.067. Conclusion: CLC treatment maintains the C/P ratio and plays an important role in maintaining membrane architecture of spermatozoa. Hence, addition of CLC may be helpful in increasing freezability of buffalo spermatozoa by increasing the C/P ratio of spermatozoa.

    In order to determine zinc and catalase content of seminal plasma in the buffalo and to study their associations with the semen characteristics, 54 semen samples were collected from 10 buffalo bulls; semen volume and sperm concentration, gross and progressive motility and viability were evaluated, seminal plasma was then harvested by centrifugation and its zinc content was estimated by atomic absorption spectrophotometer and its catalase activity determined by using a commercial kit. The zinc content of the seminal plasma (Mean +/- SEM) was recorded as 154.40 +/- 1.74 mg L(-1), while, the mean catalase value was 32.00 +/- 0.42 U mL(-1). The mean zinc values was highly correlated with sperm progressive motility and viability and with catalase values (p = 0.000 for all) and also was associated with gross motility (p = 0.020) and negatively with abnormal morphology (p = 0.049). The catalase values were highly associated with sperm progressive motility, viability and zinc content (p = 0.000 for all) and was associated with sperm gross motility (p = 0.024). For further clarification of these correlations, the samples were categorized in three groups of excellent (Ex, >90% motile, n = 33), good (Go, 80-89% motile, n = 15) and moderate (Mo, zinc and catalase values were recorded as 161.07 +/- 1.63 mg L(-1) and 33.41 +/- 0.34 U mL(-1) in Ex, 146.70 +/- 1.91 mg L(-1) and 31.01 +/- 0.67 in Go and 136.42 +/- 4.97 mg L(-1) and 26.51 +/- 0.87 U mL(-1) in Mo groups. The mean zinc value in Ex group was highly associated with sperm motility, viability and catalase values, in Go group was associated with catalase values and highly associated with sperm abnormal morphology and in Mo group it was highly associations with catalase values only. The mean catalase value in Ex group, was highly associated with sperm motility and viability, in Go group was associated with zinc content and in Mo groups was highly associated with the zinc content. These results show that seminal plasma zinc

    This study was aimed at establishing buffalo embryonic stem cells (ESCs) from in vitro fertilized (IVF), parthenogenetic, and hand-made cloned (HMC) embryos and to check their equivalency in terms of stem cell marker expression, longevity, proliferation, and differentiation pattern. ESCs derived from all three sources were found by immunofluorescence to express the pluripotency markers SSEA-4, TRA-1-60, TRA-1-81, OCT4, and SOX2 and were able to form embryoid bodies containing cells expressing genes specific to endoderm (AFP, HNF4, and GATA4), mesoderm (MSX1, BMP4, and ASA), and ectoderm (cytokeratin 8 and NF68). Reverse transcriptase PCR (RT-PCR) showed cells from all sources to be positive for pluripotency markers OCT4, SOX2, NANOG, STAT3, REX1, FOXD3, NUCLEOSTEMIN, and TELOMERASE. Pluripotency markers OCT4, SOX2, NANOG, and c-MYC were also analyzed by real-time PCR. No significant differences were observed among ESCs from all three sources for all these genes except NANOG, whose expression was higher (pcloning, chimera formation, and transgenic animal production.

    Whey based peptides are well known for their nutritional and multifunctional properties. In this context, whey proteins from buffalo colostrum & milk were digested by in vitro simulation digestion and analyzed by nano-LC-MS/MS. Functional protein association networks, gene annotations and localization of identified proteins were carried out. An ACE inhibitory peptide sorted from the library was custom synthesized and an in vitro ACE assay was performed. The study led to the identification of 74 small peptides which were clustered into 5 gene functional groups and majority of them were secretory proteins. Among the identified peptides, majority of them were found identical to angiotensin I-converting enzyme (ACE) inhibitors, antioxidant, antimicrobial, immunomodulatory and opioidal peptides. An octapeptide (m/z - 902.51, IQKVAGTW) synthesized was found to inhibit ACE with an IC50 of 300±2µM. The present investigation thus establishes newer vista for food derived peptides having ACE inhibitory potential for nutraceutical or therapeutic applications.

    The aim of the present study was to investigate the effect of Bone morphogenetic protein 4 (BMP4) stimulation on differentiation of buffalo embryonic stem (ES) cells into germ lineage cells. ES cells were subjected to in vitro differentiation in floating and adherent cultures, under different BMP4 concentrations (20, 50 and 100 ngml(-1)) for different culture intervals (4, 8 and 14 days). qPCR analysis revealed that BMP4 at a concentration of 50-100 ngml(-1) for a culture period of 14 days led to maximum induction of germ lineage genes like DAZL, VASA, PLZF (PGC-specific); SYCP3, MLH1, TNP1/2 and PRM2 (Meiotic genes); BOULE and TEKT1 (Spermatocyte markers); GDF9, ZP2 and 3 (Oocyte markers). The expression levels of all the genes were significantly higher under BMP4 differentiation as compared to BMP4 + NOGGIN and spontaneously differentiated cultures. Immunocytochemical analysis of embryoid bodies (EBs) and monolayer adherent cultures revealed expression of PGC- (c-KIT, DAZL and VASA); Meiotic- (SYCP3, MLH1 and PROTAMINE1); Spermatocyte- (ACROSIN and HAPRIN); and Oocyte- markers (GDF9 and ZP4). Western blotting was positive for VASA, GDF9 and ZP4. Oocyte-like structures (OLS) obtained in monolayer differentiated cultures harbored a big nucleus and a ZP4 coat. They showed embryonic development and progressed through 2-cell, 4-cell, 8-cell and blastocyst-like structures. Global DNA methylation analysis showed significantly (p < 0.05) decreased levels of 5-methyl-2-deoxycytidine in EBs obtained in optimum differentiation medium. The expression of meiotic markers coupled with expression of spermatocyte and oocyte markers is an indication of post-meiotic progression into spermatogenesis and oogenesis, respectively.

    Objective: To examine the oocytes maturation capacity of buffalo, sheep and goat using media containing sera of three different groups of buffaloes (regularly cycling, pregnant and repeat breeding). Methods: The buffalo, sheep and goat oocytes were matured under suitable conditions in medium containing sera of regularly cycling, pregnant and repeat breeding buffaloes. Results:The oocytes maturation rate containing buffalo oocytes cultured in media containing sera of the control group and regularly cycling group were not significantly different. However when oocytes cultured in the media containing sera of pregnant buffaloes the maturation rate were significantly declined. Further significant declined in maturation rate were observed when oocytes cultured in media containing sera of repeat breeding buffaloes. When sheep and goat oocytes cultured in the media containing control, pregnant and regularly cycling animals sera the oocytes maturation rate were not significantly different. A significant decline in maturation rate of sheep and goat oocytes were observed, when oocytes cultured in media containing sera of repeat breeding buffaloes. Conclusion: We may conclude that serum collected from normal cycling buffaloes can be used for oocytes maturation in both homogeneous and heterogeneous species.

In order to determine the somatic cell count (SCC in presence or absence of microbial isolation, 1,393 samples were collected from 285 lactating females and microbiological exams and SCC were done. Samples obtained from udders without evidence of clinical or subclinical inflammation showed infection for a great variety of microbial mastitis pathogens. The low SCC did not necessarily indicate the absence of intramammary infection, suggesting that SCC patterns used for bovine cannot be appropriate in order to control mastitis in buffalo herds.

    Approximately 50% of buffalo herds in Brazil are located in Pará state in northern Brazil. There are several properties where cattle and buffalo live and graze together, and thus, buffalo pathogens may threaten the health of cattle and vice versa. Therefore, knowledge of infectious agents of buffalo is essential for maintaining healthy livestock. Clinical disease caused by Theileria and Babesia parasites in the Asian water buffalo is not common, although these animals may act as reservoir hosts, and the detection of these hemoparasites in buffaloes is as important as it is in cattle. Studies of the infection of buffaloes by hemoparasites in Brazil are scarce. The objective of the present study was to investigate the occurrence of Piroplasmida parasites in Asian water buffaloes in the state of Pará in the Amazon region of Brazil using nested PCR assays and phylogenetic analysis. The 18S rRNA gene and ITS complete region were amplified from DNA extracted from blood samples collected from 308 apparently healthy buffaloes bred on six properties in the state of Pará, Brazil. The prevalence of positive buffalo samples was 4.2% (13/308) for Theileria spp., 3.6% (11/308) for Babesia bovis and 1% (3/308) for Babesia bigemina. Animals infected with Theileria were detected in 50% (3/6) of the assessed properties. Phylogenetic analyses indicated that the Theileria species detected in this study were closely related to Theileria buffeli, Theileria orientalis and Theileria sinensis. To our knowledge, this is the first report of Theileria in Asian water buffaloes in the Americas. The majority of Theileria-positive buffaloes (11/13) belong to a property that has a history of animals presenting lymphoproliferative disease of unknown etiology. Therefore, the present research suggests that this disorder can be associated with Theileria infection in this property. Our results provide new insights on the distribution and biological aspects of hemoparasites transmissible from

    The fatty acid binding protein 3 (FABP3) gene, known to be associated with fat percentage of milk and meat in bovines, was screened among swamp and riverine buffaloes for polymorphism detection and further association with milk fat contents. An SNP g.307C > T was identified in the intron 2 (+53 exon 2) region of FABP3 gene of Indian buffaloes. The SNP identified was genotyped in 692 animals belonging to 15 riverine, swamp and hybrid (riverine × swamp) buffalo populations of diverse phenotypes and utilities, by PCR-RFLP. A marked contrast was observed between the C and T allele frequencies in three types of buffaloes. The frequency of C allele ranged from 0.67 to 0.96 in pure swamp buffalo populations, with the highest in Mizoram (0.96). Whereas the frequency of T allele was high across all the Indian riverine buffalo breeds, ranging from 0.57 to 0.96. None of the genotypes at FABP3 g.307C > T locus was found to have significant association with milk fat and other production traits in Mehsana dairy buffalo breed. Our study revealed marked differences in the allele frequencies between riverine and swamp buffaloes at FABP3 g.307C > T locus, without any significant association with different milk traits in riverine buffaloes.

    Full Text Available Abstract Background Though India has sequenced water buffalo genome but its draft assembly is based on cattle genome BTau 4.0, thus de novo chromosome wise assembly is a major pending issue for global community. The existing radiation hybrid of buffalo and these reported STR can be used further in final gap plugging and “finishing” expected in de novo genome assembly. QTL and gene mapping needs mining of putative STR from buffalo genome at equal interval on each and every chromosome. Such markers have potential role in improvement of desirable characteristics, such as high milk yields, resistance to diseases, high growth rate. The STR mining from whole genome and development of user friendly database is yet to be done to reap the benefit of whole genome sequence. Description By in silico microsatellite mining of whole genome, we have developed first STR database of water buffalo, BuffSatDb (Buffalo MicroSatellite Database (http://cabindb.iasri.res.in/buffsatdb/ which is a web based relational database of 910529 microsatellite markers, developed using PHP and MySQL database. Microsatellite markers have been generated using MIcroSAtellite tool. It is simple and systematic web based search for customised retrieval of chromosome wise and genome-wide microsatellites. Search has been enabled based on chromosomes, motif type (mono-hexa, repeat motif and repeat kind (simple and composite. The search may be customised by limiting location of STR on chromosome as well as number of markers in that range. This is a novel approach and not been implemented in any of the existing marker database. This database has been further appended with Primer3 for primer designing of the selected markers enabling researcher to select markers of choice at desired interval over the chromosome. The unique add-on of degenerate bases further helps in resolving presence of degenerate bases in current buffalo assembly. Conclusion Being first buffalo STR database in the world

    Regucalcin is a multi-functional, calcium-binding protein with roles in calcium homeostasis, apoptosis, cell proliferation, and free radical neutralization. Regucalcin is broadly expressed in the male reproductive organs of rat and bovine; here, we report its expression in the reproductive tract of male buffalo-especially in testis, epididymis, seminal vesicle, prostate, and bulbourethral gland of buffalo-as analyzed by real-time PCR, Western blot, and immunolocalization. Regucalcin degradation in seminal plasma, despite its high abundance in vesicular fluid, was demonstrated using recombinant regucalcin co-incubated with buffalo seminal plasma. This depletion of regucalcin appears to be related to its suppressive effect on in vitro sperm capacitation, observed using the chlortetracycline assay after treating buffalo spermatozoa with recombinant protein. Indeed, addition of recombinant regucalcin to capacitating media significantly reduced (P < 0.05) the percentage of capacitated spermatozoa to 6.1 ± 0.6 from 36.4 ± 1.8 in the untreated group. Taken together, the wide distribution of regucalcin in male buffaloes, versus its degradation in the seminal plasma and suppressive effects on in vitro capacitation of spermatozoa, indicate its possible anti-capacitation role in the reproductive tract.

    The aim of this study was to evaluate the effect of different levels of inorganic chromium (Cr) on heat stress, immune response, and hormonal variation in Murrah buffalo calves during the summer season. Twenty-four growing Murrah buffalo calves were randomly allocated into four treatments for a period of 120 days. Feeding regimen was same in all the groups, except the buffalo calves in treatment groups were additionally supplemented with 0.5, 1.0, and 1.5 mg of inorganic Cr/kg dry matter. Buffalo calves were monitored daily for physiological variables and dry matter intake (DMI) and fortnightly for body weight change. Blood samples were collected at day 0, 15, 30, 45, 60, 75, 90, 105, and 120 and analyzed for heat shock protein 70 (Hsp 70), lymphocyte proliferation, neutrophil phagocytic activity, immunoglobulin, ferric reducing antioxidant power (FRAP) assay, insulin, cortisol and thyroid hormones, and Cr levels. Dietary Cr supplementation did not have any effect on DMI, growth performance, and physiological variables. However, lymphocyte proliferation, neutrophil phagocytic activity, plasma immunoglobulin, FRAP value, and plasma Cr concentration increased significantly (P calves did not show any effect on plasma levels of thyroid hormone, while concentration of insulin, cortisol, and Hsp 70 decreased (P calves reared under high ambient temperature improved heat tolerance, immune status without affecting nutrient intake, and growth performance.

  16. Comparative genomic analysis of buffalo (Bubalus bubalis NOD1 and NOD2 receptors and their functional role in in-vitro cellular immune response.

    Full Text Available Nucleotide binding and oligomerization domain (NOD-like receptors (NLRs are innate immune receptors that recognize bacterial cell wall components and initiate host immune response. Structure and function of NLRs have been well studied in human and mice, but little information exists on genetic composition and role of these receptors in innate immune system of water buffalo--a species known for its exceptional disease resistance. Here, a comparative study on the functional domains of NOD1 and NOD2 was performed across different species. The NOD mediated in-vitro cellular responses were studied in buffalo peripheral blood mononuclear cells, resident macrophages, mammary epithelial, and fibroblast cells. Buffalo NOD1 (buNOD1 and buNOD2 showed conserved domain architectures as found in other mammals. The domains of buNOD1 and buNOD2 showed analogy in secondary and tertiary conformations. Constitutive expressions of NODs were ubiquitous in different tissues. Following treatment with NOD agonists, peripheral lymphocytes showed an IFN-γ response along-with production of pro-inflammatory cytokines. Alveolar macrophages and mammary epithelial cells showed NOD mediated in-vitro immune response through NF-κB dependent pathway. Fibroblasts showed pro-inflammatory cytokine response following agonist treatment. Our study demonstrates that both immune and non-immune cells could generate NOD-mediated responses to pathogens though the type and magnitude of response depend on the cell types. The structural basis of ligand recognition by buffalo NODs and knowledge of immune response by different cell types could be useful for development of non-infective innate immune modulators and next generation anti-inflammatory compounds.

    The present study aimed to establish the impact of buserelin acetate or hCG administration on day 5 post-ovulation on subsequent luteal profile and conception rate in buffalo. The buffalo (n=45) were subjected to an estrous synchronization protocol (synthetic analog of PGF2α administered, through intramuscular route, 11 days apart), followed by artificial insemination (AI) during mid to late estrus. On day 5 post-ovulation, buffalo were administered (i.m.) normal saline (Control, n=14), buserelin acetate (20μg, d5-BA, n=14) or human chorionic gonadotropin (3000IU, d5-hCG, n=17). Ovarian ultrasonography was conducted on the day of induced estrus and on days 0, 5, 12, 16 and 21 post-ovulation to assess preovulatory follicle or corpus luteum (CL) diameter. Also, on these days, jugular vein blood sampling was conducted for the estimation of plasma progesterone. First service conception rate was greater (χ(2)=5.18, P>0.05) in d5-BA and d5-hCG groups (71.4% and 47.1%, respectively) as compared to control (28.6%). Both treatment groups had a greater (Ppost-treatment period in comparison to that control treatment group. Treatment-induced accessory CL formation was observed in 92.9% and 76.5% buffalo of d5-BA and d5-hCG groups, respectively. In conclusion, buserelin acetate and hCG administration on day 5 post-ovulation leads to accessory CL formation that may have a role in enhancing conception rate.

    The objective was to investigate the effect of recipient oocyte age and the interval from activation to fusion on developmental competence of buffalo nuclear transfer (NT) embryos. Buffalo oocytes matured in vitro for 22 h were enucleated by micromanipulation under the spindle view system, and a fetal fibroblast (pretreated with 0.1 μg/mL aphidicolin for 24 h, followed by culture for 48 h in 0.5% fetal bovine serum) was introduced into the enucleated oocyte, followed by electrofusion. Both oocytes and NT embryos were activated by exposure to 5 μM ionomycin for 5 min, followed by culture in 2 mM 6-dimethyl-aminopurine for 3 h. When oocytes matured in vitro for 28, 29, 30, 31, or 32 h were activated, more oocytes matured in vitro for 30 h developed into blastocysts in comparison with oocytes matured in vitro for 32 h (31.3 vs 19.9%, P fusion (P fusion. However, 3 of 16 recipients were pregnant following transfer of blastocysts developed from the NT embryos activated at 3 h after fusion, and two of these recipients maintained pregnancy to term. We concluded that the developmental potential of buffalo NT embryos was related to recipient oocyte age and the interval from fusion to activation.

    Cloning in bovine species is marred by low efficiency of blastocyst formation. Any increase in the efficiency of blastocyst formation upon nuclear transfer will greatly enhance the efficiency of cloning. In the present study, the effect of various media, protein sources, and growth factors on the development of cloned buffalo embryos was evaluated. Among various combinations tested, culture of cloned embryos in TCM-199 media on the feeder layer of Buffalo Oviductal Epithelial Cells (BOEC) in the presence of bovine serum albumin-free fatty acid (BSA-FFA) and leukemia inhibitory factor (LIF) provided most suitable environment for efficient development of cloned blastocysts. Under these conditions, we achieved a blastocyst formation rate of 43%, which is better than those reported previously. Because preimplantation embryonic development, in vivo, occurs in an environment of oviductal cells, the blastocysts generated by this method may presumably be more suitable for implantation and further development. Additionally, we generated green blastocysts from enucleated oocytes by transfer of nuclei from cells transfected with EGFP transgene, showing possibility of transgenesis via cloning in this species. To our knowledge, this is the first report regarding the production of transgenic cloned buffalo embryos and their developmental competence with respect to various media, cocultures, and supplements.

    It is well known that excessive accumulation of fluorides can exert toxic effects on various tissues and organs so as to severely damage the health and production of animals. The aim of this study was to determine beneficial effect of boron on nutrient utilization in buffalo calves exposed to high fluoride (F) ration. For this purpose, we used three groups of four male Murrah buffalo calves (body weight 98-100 kg, aged 6-8 month) each. Control animal was given only basal diet and concentrate mixture. However, treatment I animals were fed basal diet, concentrate mixture, and F [as NaF, 60 ppm of dry matter (DM)]. The treatment II animals were fed basal diet, concentrate mixture, F (as NaF, 60 ppm of DM), and B (as sodium tetraborate, 140 ppm of DM). After 90 days of experimental feeding, a metabolism trial of 7 days duration was conducted to study the treatment effect on nutrient utilization of proximate nutrients, absorption, excretion, and retention of N, Ca, P, Fe, Zn, Cu, and F. Dietary F significantly (p matter intake and increased the apparent digestibility, absorption, and retention of F. However, boron supplementation significantly (p matter intake, fecal excretion, and percent of absorbed F excreted via urine. Apparent digestibility of proximate nutrients (viz. DM, crude protein, crude fiber, ether extract, and nitrogen free extract) was unaffected on either F or F+B treatment. However, absorption and excretion of N, Ca, P, Fe, Zn, and Cu were affected significantly (p < 0.05) on F or F+B treatment. These findings suggest that fluoride-containing diet for short duration has effect on nutrient utilization, and boron at 140-ppm dose level, in general, antagonized the absorption and retention of F and also improved the feed intake in buffalo calves.

    The present investigation was done to study the effect of caspase-9 inhibitor Z-LEHD-FMK, on in vitro produced buffalo embryos. Z-LEHD-FMK is a cell-permeable, competitive and irreversible inhibitor of enzyme caspase-9, which helps in cell survival. Buffalo ovaries were collected from slaughterhouse and the oocytes were subjected to in vitro maturation (IVM), in vitro fertilization (IVF) and in vitro culture (IVC). The culture medium was supplemented with Z-LEHD-FMK at different concentrations i.e. 0 μM (control), 10 μM, 20 μM, 30 μM and 50 μM during IVM and IVC respectively. After day-2 post-insemination, the cleavage rate was significantly higher (74.20 ± 5.87% at PZ-LEHD-FMK than at any other concentration. Same trend was observed in the blastocyst production rate which was higher at 20 μM (27.42 ± 2.94% at PZ-LEHD-FMK which showed apoptotic index significantly lower (1.88 ± 0.87 at PZ-LEHD-FMK treated blastocysts. The quantitative gene expression of CHOP and HSP10 genes showed significant increase (PZ-LEHD-FMK, while, HSP40 showed significant increase (PZ-LEHD-FMK concentrations. From the afore mentioned results we conclude that, Z-LEHD-FMK at 20 μM increased the cleavage and blastocyst rate of buffalo pre-implantation embryos also affecting the rate of apoptosis and cellular stress at various concentrations.

    The presence of Aquaporins 1 (AQP1) and 9 (AQP9), integral membrane water channels that facilitate rapid passive movement of water and solutes, was immunohistochemically detected in the excurrent ducts collected from sexually mature buffalo bulls of proven fertility during the mating (late autumn-winter) and non-mating (late spring to the beginning of autumn) seasons. Furthermore, the research was performed also on the epididymal cauda of a senile buffalo bull with inactive testis. Aquaporins 1 and 9 were immunolocalized at distinct levels. In the efferent ducts, AQP1 immunoreactivity was strongly evidenced at the apical surface of the non-ciliated cells and weakly along the basal membrane of the epithelial cells. The latter reactivity disappeared during the non-mating season. No AQP1 immunoreactivity was detected in the epithelium of epididymis and vas deferens, whereas AQP1 was expressed in the smooth muscle layer of the vas deferens. Aquaporin 1 was present in the blood vessels and in small nerve bundles all along the genital tract. The supranuclear zone of the epididymal principal cells was AQP9 immunoreactive, limited to the corpus and cauda regions, and vas deferens. The samples collected in the two reproductive seasons showed a weaker AQP9 immunoreactivity during the non-mating season. A typical AQP9 immunoreactivity was noticed in the old buffalo examined. The tested AQP molecules showed a different expression pattern in comparison with laboratory mammals, primates, equine, dog and cat. In addition, seasonal differences were noticed which are possibly useful in regard to the comprehension of the morphophysiology of reproduction in the bubaline species, which are still a matter of debate.

    Phosphorylation of tyrosine residues on sperm protein is a known indicator of capacitation and a major intracellular signalling event. There is evidence that sperm cryopreservation promotes tyrosine phosphorylation and is associated with reduced fertility of spermatozoa. Under this study, cryoprotective role of different additives namely taurine, trehalose, catalase and 4-bromophenacyl bromide on buffalo sperm quality was evaluated. Buffalo semen was cryopreserved in tris-based egg yolk extender supplemented with additives like taurine (50 mm) or trehalose (100 mm) or 4-bromophenacyl bromide (200 μm) or catalase (100 U/ml) and used for assessment of levels of tyrosine phosphorylation in frozen-thawed spermatozoa. The results obtained were compared with the level of protein tyrosine phosphorylation of semen cryopreserved in tris-based egg yolk extender without additives. Proteins were extracted from a total number of nine ejaculates from three individual buffalo bulls chosen at random and analysed for tyrosine phospho-proteins using SDS-PAGE followed by immunoblotting. Monoclonal anti-phosphotyrosine antibody (Clone pT-154) was used as primary antibody followed by treatment with HRP-conjugated secondary antibody. Signals were detected on X-ray film using chemiluminescence. Nine proteins (p20, p30, p32, p38, p49, p56, p59, p72 and p86) were found to be tyrosine phosphorylated in cryopreserved spermatozoa. Supplementation of additives significantly (p<0.05) reduced the level of protein tyrosine phosphorylation in spermatozoa. Moreover, this study showed improved (p<0.05) post-thaw motility, viability and membrane integrity of spermatozoa on addition of these additives. The results obtained clearly indicate reduced level of capacitation like changes on supplementation of additives in terms of protein tyrosine phosphorylation.

    Activation of innate immunity initiates various cascades of reactions that largely contribute to defense against physical, microbial or chemical damage, prompt for damage repair and removal of causative organisms as well as restoration of tissue homeostasis. Genetic polymorphism in innate immune genes plays prominent role in disease resistance capabilities in various breeds of cattle and buffalo. Here we studied single nucleotide variations (SNP/SNV) and haplotype structure in innate immune genes viz CHGA, CHGB, CHGC, NRAMP1, NRAMP2, DEFB1, BNBD4, BNBD5, TAP and LAP in Gir cattle and Murrah buffalo. Targeted sequencing of exonic regions of these genes was performed by Ion Torrent PGM sequencing platform. The sequence reads obtained corresponding to coding regions of these genes were mapped to reference genome of cattle BosTau7 by BWA program using genome analysis tool kit (GATK). Further variant analysis by Unified Genotyper revealed 54 and 224 SNPs in Gir and Murrah respectively and also 32 SNVs was identified. Among these SNPs 43, 36, 11,32,81,21 and 22 variations were in CHGA, CHGB, CHGC, NRAMP1, NRAMP2, DEFB1 and TAP genes respectively. Among these identified 278 SNPs, 24 were found to be reported in the dbSNP database. Variant analysis was followed by structure formation of haplotypes based on multiple SNPs using SAS software revealed a large number of haplotypes. The SNP discovery in innate immune genes in cattle and buffalo breeds of India would advance our understanding of role of these genes in determining the disease resistance/susceptibility in Indian breeds. The identified SNPs and haplotype data would also provide a wealth of sequence information for conservation studies, selective breeding and designing future strategies for identifying disease associations involving samples from distinct populations.

    In this study, we describe the production of buffalo parthenogenetic blastocysts and subsequent isolation of parthenogenetic embryonic stem cell (PGESC)-like cells. PGESC colonies exhibited dome-shaped morphology and were clearly distinguishable from the feeder layer cells. Different stages of development of parthenogenetic embryos and derived embryonic stem cell (ESC)-like cells expressed key ESC-specific markers, including OCT-4, NANOG, SOX-2, FOXD3, REX-1, STAT-3, TELOMERASE, NUCLEOSTEMIN, and cMYC. Immunofluorescence-based studies revealed that the PGESCs were positive for surface-based pluripotent markers, viz., SSEA-3, SSEA-4, TRA 1-80, TRA 1-60, CD-9, and CD-90 and exhibited high alkaline phosphatase (ALP) activity. PGEC cell-like cells formed embryoid body (EB)-like structures in hanging drop cultures and when cultured for extended period of time spontaneously differentiated into derivatives of three embryonic germ layers as confirmed by RT-PCR for ectodermal (CYTOKERATIN8, NF-68), mesodermal (MSX1, BMP-4, ASA), and endodermal markers (AFP, HNF-4, GATA-4). Differentiation of PGESCs toward the neuronal lineage was successfully directed by supplementation of serum-containing media with retinoic acid. Our results indicate that the isolated ESC-like cells from parthenogenetic blastocyst hold properties of ESCs and express markers of pluripotency. The pluripotency markers were also expressed by early cleavage-stage of buffalo embryos.

    Tuberculosis is a disease with a great zoonotic potential. It is considered a major obstacle to cattle production and is responsible for severe losses in several production systems. A comparative cervical test (CCT) was performed in 1140 buffaloes from different mesoregions of the state of Pará, Brazil, with the aim of comparing the sensitivity and specificity of CCT with histopathological examination and bacterial culture. Of the animals tested using CCT, 4.65% (53/1140) were positive, 2.98% (34/1140) were inconclusive, and 92.36% (1053/1140) were negative. Among the 168 sacrificed animals, 33 were positive, 18 were inconclusive, and 117 were negative by CCT, and samples from the sacrificed animals were collected for histopathological examination and bacterial culture. A qualitative evaluation of the tuberculin test was performed by comparing the test results with the histopathological and bacteriological results. The latter two tests yielded a prevalence of 4.16%, a sensitivity of 71.43%, and a specificity of 82.61%. Based on these results, we concluded that CCT yielded satisfactory results and can be applied in diagnostic studies in buffaloes. The prevalence rate obtained using three distinct diagnostic methods suggests that Mycobacterium bovis was present in a few animals in the population evaluated.

    Fifteen dairy buffaloes of a farm in the state of Kerala, India developed fatal oriental theileriosis within 2 months of their procurement. Typical piroplasms of Theileria orientalis were observed in the erythrocytes of all affected animals by Giemsa-Leishman staining of blood smears. Case fatality rate was 87·5% (seven out of eight) in the clinically progressed cases. Therapeutic management with anti-theilerial drugs buparvaquone and oxytetracycline led to recovery of seven other animals in less advanced stages of the disease. The aim of this study was to determine the reasons for increased virulence of this pathogen, hitherto considered to be benign. Acute haemolytic anaemia was the predominant haematological finding in the affected animals. Lymphocytic infiltration and degeneration of vital organs leading to functional derangement was the cause of the high mortality. Identification of T. orientalis was confirmed by polymerase chain reaction (PCR). DNA sequencing of the PCR products revealed close identity with already reported sequences of T. orientalis/buffeli N2 genotype. The sequences were deposited in GenBank with accession number KM609973 and KM043772. Rhipicephalus ticks, previously not reported as vectors for oriental theileriosis, were identified as the potential vectors. This is the first report of fatal oriental theileriosis in Asian water buffaloes.

    Full Text Available Aim: The present study was carried out to examine the relationships among frozen-thawed semen fertility, physical parameters, seminal quality, and testosterone concentration in Murrah buffalo bulls. Materials and Methods: A total of 30 breeding Murrah buffalo bulls (either progeny tested or under progeny testing program were randomly selected from two government bull farms in Punjab. None of the bulls selected for this study had any preceding physical abnormality. A field fertility trial was conducted to determine the first service conception rate (FSCR. The number of females inseminated per bull semen was 10. All the bulls were inspected for structural soundness, measurement of scrotal circumference, testicular biometry, and internal pelvic area (IPA. Frozen-thawed semen was evaluated for total motility, progressive motility, viability, concentration, abnormality, and hypo-osmotic swelling test (HOST. Testosterone was estimated in blood plasma, seminal plasma as well as frozen-thawed semen extracts for establishing relationship. Results: The FSCR was 48% in the bulls having a scrotal circumference of ≥44 cm, although, there was no significant correlation between FSCR and scrotal circumference. Similarly, no consistent relationship existed between sperm concentration and scrotal circumference. A positive correlation was observed between IPA and FSCR (r=0.294. Of the six post-thaw seminal components (total motility, progressive motility, viability, HOST (%, total abnormality and concentration only total motility had a high significant (p<0.01 correlation with FSCR (r=0.694. Varied correlations existed between other seminal parameters and fertility. Using a simple regression analysis, the post-thaw motility, IPA, prepuce length and testosterone (independent variables combined to explain approximately 62% of the variation in the FSCR (dependent variable. Conclusion: The present study indicated that despite low to high correlations between seminal

    Nucleotide binding and oligomerization domain 2 (NOD2), a member of intracellular NOD-like receptors (NLRs) family, recognizes the bacterial peptidoglycan, muramyl dipeptide (MDP) and initiates host immune response. The precise ligand recognition mechanism of NOD2 has remained elusive, although studies have suggested leucine rich repeat (LRR) region of NOD2 as the possible binding site of MDP. In this study, we identified multiple transcripts of NOD2 gene in buffalo (buNOD2) and at least five LRR variants (buNOD2-LRRW (wild type), buNOD2-LRRV1-V4) were found to be expressed in buffalo peripheral blood mononuclear cells. The newly identified buNOD2 transcripts were shorter in lengths as a result of exon-skipping and frame-shift mutations. Among the variants, buNOD2-LRRW, V1, and V3 were expressed more frequently in the animals studied. A comparative receptor-ligand interaction study through modeling of variants, docking, and molecular dynamics simulation revealed that the binding affinity of buNOD2-LRRW towards MDP was greater than that of the shorter variants. The absence of a LRR segment in the buNOD2 variants had probably affected their affinity toward MDP. Notwithstanding a high homology among the variants, the amino acid residues that interact with MDP were located on different LRR motifs. The binding free energy calculation revealed that the amino acids Arg850(LRR4) and Glu932(LRR7) of buNOD2-LRRW, Lys810(LRR3) of buNOD2-LRRV1, and Lys830(LRR3) of buNOD2-LRRV3 largely contributed towards MDP recognition. The knowledge of MDP recognition and binding modes on buNOD2 variants could be useful to understand the regulation of NOD-mediated immune response as well as to develop next generation anti-inflammatory compounds.

    A total of 33 macroscopically visible (3-11 × 1-5 mm) sarcocysts of Sarcocystis fusiformis were excised from the oesophagus of 12 freshly slaughtered water buffalos in Giza, Egypt. Genomic DNA was extracted from the sarcocysts, and all isolates were characterised at the mitochondrial cytochrome c oxidase subunit I (cox1) gene through PCR amplification and direct sequencing, whereas a few selected isolates were characterised at the 18S and 28S ribosomal (r) RNA genes and the internal transcribed spacer 1 (ITS1) region of the nuclear rDNA unit following cloning. Among the 33 cox1 sequences (1,038-bp long), there was a total of 13 haplotypes, differing from each other by one to seven substitutions and sharing an identity of 99.3-99.9 %. In comparison, the sequence identity was 98.8-99.0 % among eight complete 18S rRNA gene sequences (1,873-1,879-bp long), 98.1-100 % among 28 complete ITS1 sequences (853-864-bp long) and 97.4-99.6 % among five partial 28S rRNA gene sequences (1,607-1,622 bp). At the three nuclear loci, the intraspecific (and intra-isolate) sequence variation was due to both substitutions and indels, which necessitated cloning of the PCR products before sequencing. Some additional clones of the 18S and 28S rRNA genes were highly divergent from the more typical clones, but the true nature of these aberrant clones could not be determined. Sequence comparisons and phylogenetic analyses based on either 18S rRNA gene or cox1 nucleotide sequences, placed S. fusiformis closest to Sarcocystis cafferi from the African buffalo, but only the analyses based on cox1 data separated the two taxa clearly from each other and showed that they were separate species (monophyletic clusters and 93 % sequence identity at cox1 versus interleaved sequences and 98.7-99.1 % sequence identity at the 18S rRNA gene). Two cats experimentally infected with sarcocysts of S. fusiformis started shedding small numbers of sporocysts 8-10 days post-infection (dpi) and were euthanized 15

    Full Text Available High roughage diet causes more methane emissions; however, the total methanogen abundance is not influenced by roughage proportion. Technologies to reduce methane emissions are lacking, and development of inhibitors and vaccines that mitigate rumen-derived methane by targeting methanogens relies on present knowledge of the methanogens. In this work, we have investigated molecular diversity of rumen methanogens of Surti buffalo. DNA from rumen fluid was extracted, and 16S rRNA encoding genes were amplified using methanogen specific primer to generate 16S rDNA clone libraries. Seventy-six clones were randomly selected and analysed by RFLP resulting in 21 operational taxonomic units (OTUs. BLAST analysis with available sequences in database revealed sequences of 13 OTUs (55 clones showing similarity with Methanomicrobium sp, 3 OTUs (15 clones with Methanobrevibacter sp. The remaining 5 OTUs (6 clones belonged to uncultured archaea. The phylogenetic analysis indicated that methanogenic communities found in the library were clustered in the order of Methanomicrobiales (18 OTUs and Methanobacteriales (3 OTUs. The population of Methanomicrobiales, Methanobacteriales, and Methanococcales were also observed, accounting for 1.94%, 0.72%, and 0.47% of total archaea, respectively.

    This study examines the differential role of calcium signaling pathway(s) in histamine-induced uterotonic action during early and mid-pregnancy stages in buffaloes. Compared to mid pregnancy, tonic contraction, amplitude and mean-integral tension were significantly increased by histamine to produce myometrial contraction during early pregnancy with small effects on phasic contraction and frequency. Although uterotonic action of histamine during both stages of pregnancy is sensitive to nifedipine (a L-type Ca(2+) channels blocker) and NNC55-0396 (T-type Ca(2+) channels blocker), the role of extracellular calcium seems to be more significant during mid-pregnancy as in this stage histamine produced only 9.38±0.96% contraction in Ca(2+) free-RLS compared to 21.60±1.45% in uteri of early pregnancy stage. Intracellular calcium plays major role in histamine-induced myometrial contraction during early pregnancy as compared to mid pregnancy, as in the presence of cyclopiazonic acid (CPA) Ca(2+)-free RLS, histamine produced significantly higher contraction in myometrial strips of early-pregancy in comparison to mid-pregnancy (10.59±1.58% and 3.13±0.46%, respectively). In the presence of U-73122, the DRC of histamine was significantly shifted towards right with decrease in maximal effect (Emax) only in early pregnancy suggesting the predominant role of phospholipase-C (PL-C) in this stage of pregnancy.

The Ca and Mg content of the seminal plasma (Mean ± SEM were recorded as 22.36 ± 0.52 mg dl-1 and 11.94 ± 0.36 mg dl-1 respectively, while, its mean TAC value was 1.50 ± 0.02 mmol L-1. The mean Ca value was highly associated with sperm progressive motility, gross motility, viability (P = 0.000 for all, negatively with semen volume (P = 0.01, and with Mg and TAC values (P = 0.000 for both. The mean Mg values was highly associated with sperm progressive motility, gross motility and viability and seminal plasma Ca and TAC (P = 0.000 for all and negatively associated with semen volume (P = 0.014. The mean TAC values was highly associated with sperm progressive motility, gross motility and viability and seminal plasma Ca and Mg (P = 0.000 for all. For further clarification of these associations, the data was categorized in three groups of excellent (Ex, >90% motile, n = 33, good (Go, 80-89% motile, n = 15 and moderate (Mo, <79% motile, n = 6 according to their percentage of sperm motility. The mean progressive motility in Ex group was 92.24 ± 0.51%, in Go group it was 81.66 ± 0.62 %, and in Mo group it was 71.66 ± 1.05 %. The mean Ca, Mg and TAC values were respectively recorded as 25.12 ± 0.29 mg dl-1, 13.78 ± 0.20 mg dl-1, and 1.57 ± 0.009 mmol L-1 in Ex, 18.74 ± 0.63 mg dl-1, 9.14 ± 0.33mg dl-1, and 1.42 ± 0.044 mmol L-1 in Go, and 17.34 ± 0.18 mg dl-1, 8.06 ± 0.25 mg dl-1, and 1.23± 0.05 mmol L-1 in Mo groups. The associations in groups are discussed. These results show that seminal plasma Ca and Mg content and TAC are associated with semen

    The quantitative real time PCR (qRT-PCR) has become an important tool for gene-expression analysis for a selected number of genes in life science. Although large dynamic range, sensitivity and reproducibility of qRT-PCR is good, the reliability majorly depend on the selection of proper reference genes (RGs) employed for normalization. Although, RGs expression has been reported to vary considerably within same cell type with different experimental treatments. No systematic study has been conducted to identify and evaluate the appropriate RGs in spermatozoa of domestic animals. Therefore, this study was conducted to analyze suitable stable RGs in fresh and frozen-thawed spermatozoa. We have assessed 13 candidate RGs (BACT, RPS18s, RPS15A, ATP5F1, HMBS, ATP2B4, RPL13, EEF2, TBP, EIF2B2, MDH1, B2M and GLUT5) of different functions and pathways using five algorithms. Regardless of the approach, the ranking of the most and the least candidate RGs remained almost same. The comprehensive ranking by RefFinder showed GLUT5, ATP2B4 and B2M, MDH1 as the top two stable and least stable RGs, respectively. The expression levels of four heat shock proteins (HSP) were employed as a target gene to evaluate RGs efficiency for normalization. The results demonstrated an exponential difference in expression levels of the four HSP genes upon normalization of the data with the most stable and the least stable RGs. Our study, provides a convenient RGs for normalization of gene-expression of key metabolic pathways effected during freezing and thawing of spermatozoa of buffalo and other closely related bovines.

    This study investigated the transmission of foot-and-mouth disease virus (FMDV) from experimentally infected Indian buffalo to in-contact naïve and vaccinated cattle and buffalo. In each of six rooms, two donor buffalo that had been inoculated with FMDV were housed for five days with four recipient animals, comprising one vaccinated buffalo, one vaccinated calf, one unvaccinated buffalo and one unvaccinated calf. Vaccination was carried out with current Indian vaccine strain (O/IND/R2/75) and challenged on 28 days post-vaccination with an antigenically similar strain (O/HAS/34/05). All 12 donor buffalo and the six unvaccinated cattle and six unvaccinated calves developed clinical signs of foot-and-mouth disease (FMD). In contrast, all six vaccinated cattle (100%) and four out of six vaccinated buffalo (66.6%) were protected from disease but all became infected with FMDV. This confirms that buffalo have the potential to spread FMD by direct contact and that vaccination can block this spread. The numbers of animals in the study were too small to determine if the differences in clinical protection afforded by vaccination of cattle and buffalo are significant and warrant a different dose regime.

A presença de anticorpos é um indicativo da circulação desses protozoários em búfalos das propriedades estudadas, representando uma fonte de infecção para outros animais, assim como o possível envolvimento em distúrbios reprodutivos nessa espécie.To investigate the occurrence of antibodies IgG anti-Neospora caninum and Toxoplasma gondii, blood samples were collected from 374 adult female water buffaloes originated from 14 production units located in 13 counties of the state of Pará. The sera were subjected to indirect fluorescent antibody (IFA, using titers of 200 and 64 as IFA cut off points for N. caninum and T. gondii, respectively. Hundred and fifty three (40.9% buffaloes were sero-positive for N. caninum, with 100% of the properties being sources of infection. Four buffaloes (1.1% in four farms were seropositive for T. gondii, and one buffalo cow (0.27% was seropositive for the two parasites. The presence of antibodies indicates that these protozoan parasites are circulating among buffaloes from the properties studied, representing a source of infection to other animals, as well as a possible cause of reproductive disorders in this species.

    Full Text Available This study aimed to investigate the frequency of homologous antibodies of IgG class against Borrelia burgdorferi in buffaloes in the state of Pará, Brazil. Blood serum samples from 491 buffaloes were analyzed by means of the indirect ELISA test, using crude antigen produced from a cultivar of the North American strain G39/40 of B. burgdorferi. There were 412 positive samples (83.91%, and there was no statistically significant difference in the proportions of positive animals between the 81.69% (232/284 originating from Marajó Island and the 86.96% (180/207 from the continental area of the state of Pará. In all the municipalities studied, the frequency of positive findings of antibodies against B. burgdorferi among the animals ranged from 63.6% to 92.9%. The high numbers of seropositive animals can be explained by the frequent presence of the tick Rhipicephalus (Boophilusmicroplus, and by the possible existence of spirochetes of the genus Borrelia infecting buffaloes in the region studied, although specific studies are needed to confirm this relationship. These factors suggest that a cross-reaction exists between the North American strain G39/40 of B. burgdorferi, which is used as an antigenic substrate, and the species of Borrelia spp. that possibly infects buffaloes in the state of Pará.Este estudo teve como objetivo investigar a frequência de anticorpos homólogos da classe IgG contra Borrelia burgdorferi em búfalos do estado do Pará.

    Full Text Available Conjugated Linoleic Acids (CLAs comprise a family of positional and geometric isomers of linoleic acid. The main form of CLA, cis-9, trans-11-C18:2 show positive effects in cancer prevention and treatment. The major dietary sources of these fatty acids are derived from ruminant animals, in particular dairy products. In these animals, the endogenous synthesis mainly occurs in mammary gland by the action of enzyme Stearoyl CoA Desaturase (SCD. Different levels of expression and activity of SCD in mammary gland can explain partially the variation of CLA levels in fat milk. Considering a great fat concentration in bubaline milk and the benefit of a high and positive correlation between fat milk and CLA production, this study was carried on with the intention of sequencing and characterizing part of the gene that codifies SCD in buffaloes. Genomic DNA was extracted from blood samples of lactating bubaline which begins to the breed Murrah. After the (acho que nao precisa desse the extractions, PCR (Polymerase Chain Reaction reactions were made by using primers Z43D1 and E143F1. The fragments obtained in PCR were cloned into “T” vectors and transformed in competent cells DH10B line. After this, three samples of each fragment were sequenced from 5’ and 3’ extremities using a BigDye kit in an automatic sequencer. Sequences were edited in a consensus of each fragment and were submitted to BLAST-n / NCBI for similarity comparisions among other species. The sequence obtained with Z43D1 primers shows 938 bp enclosing exons 1 and 2 and intron 1. The primers E143F1 show 70 bp corresponding to exon 3 of bubaline SCD gene. Similarities were obtained between 85% and 97% among bubaline sequences and sequences of SCD gene described in human, mouse, rat, swine, bovine, caprine and ovine species. This study has permitted the identification and partial characterization of SCD codifing region in Bubalus bubalis specie.

    Through the use of radioimmunoassay (RIA) it was determined blood serum concentration of triiodothyronine (T{sub 3}) and thyroxine (T{sub 4}) (n=78) for two different water buffalo racial groups. Blood serum was collected from young and adult animals belonging to two farms in Castanhal country, state of Para, Brazil, through the year of 1988. The serum levels of T{sub 3} and T{sub 4} were statistically correlated with climatic parameters, e.g., pluviometric precipitation, environmental temperature, humidity, light intensity variation and physiological factors such as age, breed and sex. It was identified two seasons during experiment, one season the rainfall period with high precipitation rates and the other one was considered as dry season, with low precipitation rates. The average rate of temperature and humidity have shown no significant statistic difference between the two seasons. On the other hand, it was found a significant relationship between luminosity and seasons, since when the luminosity decreases the pluviometric rates increases. (author). 51 refs, 15 figs, 15 tabs.

    This study was conducted to determine the chromium content of different feedstuffs, their estimated requirement, and effect of dietary Cr supplementation on nutrient intake, nutrient utilization, growth performance, and mineral balance in buffalo calves during summer season. Levels of Cr was higher in cultivated fodder, moderate in cakes and cereal grains, while straw, grasses, and non-conventional feeds were poor in Cr content. To test the effect of Cr supplementation in buffalo calves, 0, 0.5, 1.0, and 1.5 ppm of inorganic Cr were fed to 24 buffalo calves. Buffalo calves were randomly assigned to four treatments (n = 6) and raised for 120 days. A metabolic trial for a period of 7 days was conducted after 3 months of dietary treatments. Blood samples were collected at fortnight interval for plasma mineral estimation. The results suggested that dietary Cr supplementation in summer did not have any affects (P > 0.05) on feed consumption, growth performance, nitrogen balance, and physiological variables. However, dietary Cr supplementation had significant effect (P 0.05) balance and plasma levels of other trace minerals. The estimated Cr requirement of buffalo calves during summer season was calculated to be 0.044 mg/kg body mass and 10.37 ppm per day. In conclusion, dietary Cr supplementation has regardless effect on feed consumption, mass gain, and nutrient utilization in buffalo calves reared under heat stress conditions. However, supplementation of Cr had positive effect on its balance and plasma concentration without interacting with other trace minerals.

    The postthaw motility and fertility of frozen-thawed buffalo spermatozoa are substantially low as compared with those of cattle sperm. The sperm motility and fertility have been positively correlated with the antioxidant enzyme activities of human and canine sperm. However, the extent of antioxidant enzyme loss during cryopreservation, although reported for human and cattle sperm, is still not clear for buffalo sperm. Thus, in the present study, an attempt was made to determine the activities of various antioxidant enzymes in buffalo spermatozoa cryopreserved for various durations (0, 30, and 60 days) and the mechanism of antioxidant enzyme loss, if any, during the process. Total superoxide dismutase (SOD) activity of cryopreserved sperm decreased and that of extended seminal plasma increased progressively with the increase in duration of cryopreservation indicating the possible time-dependent leakage of these enzymes from cryopreserved sperm into the extended seminal plasmas. The catalase and glutathione peroxidase (GPx) enzyme activities could not be detected in buffalo sperm but could be detected in fresh and extended seminal plasmas. Total GPx activities of extended seminal plasma decreased progressively with the increase in duration of cryopreservation. To confirm the presence of these enzymes at protein levels, specific antioxidant enzymes such as Cu,Zn SOD of 16 kDa and three molecular weight forms (57.7, 40.9, and 26.05 kDa) of GPx-1 were detected in buffalo sperm by Western blot. Furthermore, the intensities of 16-kDa Cu,Zn SOD in 60-day cryopreserved sperm and those of two low-molecular-weight forms of GPx-1 (40.9 and 26.05 kDa) in 30-day cryopreserved sperm decreased significantly (P Zn SOD proteins are distributed over the acrosomal region of noncryopreserved buffalo spermatozoa, and the fluorescence signal decreased substantially in 60-day cryopreserved sperm. Thus, the present study reported that there is temporal leakage of Cu,Zn SOD and loss of

    The ATP-binding cassette sub-family G member 2 ( ABCG2) protein plays a crucial role on the milking traits of cattle. But its population genetic characteristics and association with milk produc-tion in buffalo were unclear. In this study, ABCG1 exon 9 of 466 buffalo sampled from 4 river type and 9 swamp type populations were examined using PCR-SSCP and PCR product direct sequencing techniques. The results revealed that sequences of ABCG1 exon 9 in river type and swamp type buffalo were identical, which consist of 251 nucleotides with no SNP discovered, but one T > C substitution (g. SNP44769 T >C) was detected in intron 9. Compared with published data of the bovidae species in GenBank database, one G > A substitution (c. SNP1018 G > A) was found in one river buffalo sequence and lead to the change of the 340th amino acid residues from Valine to Isoleucine (p. V340I) in ABCG2. And the numbers of nucleotide sequence differences among buffalo, cattle, goat and sheep were 5, 8, 11, respectively, which suggest that there are distinct genetic differences between buffalo and the other bovidae species. The results in the present study indicate that ABCG1 exon 9 has been fixed in buffalo and probably had no direct correlation with the trait of buffalo milk yield.%三磷酸腺苷结合转运蛋白G超家族成员2 (ABCG2)对普通奶牛泌乳性状有直接影响.水牛中该基因的遗传特征与产奶性状间是否有遗传关联目前还不十分清楚.本文采用PCR-SSCP和PCR产物直接测序相结合的技术,对4个河流型水牛群体和9个沼泽型水牛群体共计466个个体的ABCG2基因第9外显子进行了变异检测.结果表明,水牛ABCG2基因第9外显子由251个核苷酸组成,所有的河流型和沼泽型水牛序列相同,未发现SNP位点,但在第9内含子内检测到1个T>C替换(g.SNP44769 T>C).与GenBank数据库中已发表的牛科物种同源序列比对后发现,数据库中一条河流型水牛序列该外显子第66

    The present study evaluated the effects of glial cell line-derived neurotrophic factor (GDNF), fibroblast growth factor (FGF) 2 and epidermal growth factor (EGF) on proliferation and the expression of some genes in spermatogonial cells. Spermatogonial cells were isolated from prepubertal buffalo testes and enriched by double enzyme treatment, filtration through 80- and 60-μm nylon mesh filters, differential plating on lectin-coated dishes and Percoll density gradient centrifugation. Cells were then cultured on a buffalo Sertoli cell feeder layer and formed colonies within 15-18 days. The colonies were found to predominantly contain undifferentiated Type A spermatogonia because they bound Dolichos biflorus agglutinin and did not express c-kit. The colonies expressed alkaline phosphatase, NANOG, octamer-binding transcription factor (OCT)-4 and tumour rejection antigen (TRA)-1-60. Cells were subcultured for 15 days, with or without growth factor supplementation. After 15 days, colony area and the relative mRNA abundance of PLZF were higher (Pgrowth factor supplementation. In the Sertoli cell feeder layer, EGF and FGF2 decreased (Pgrowth factors was developed for the short-term culture of buffalo spermatogonia.

    Full Text Available Ruminal degradable protein (RDP is considered essential for ruminal microbial growth. This not only improves the ruminal fermentation but it also ensures an adequate supply of microbial protein to the host animal. One of the most effective methods to enhance ruminal microbial protein supplies to the host is an efficient utilization of non-protein nitrogen substances (Sarwar et al., 2004. This makes the ruminant animal production cost-effective through minimizing its ruminally undegradable protein (RUP needs (Blummel et al., 1999. Urea can be used all or a part of the supplemental protein to meet the dairy cow requirement (Russell et al., 1992. It is documented that exotic lactating cows perform equally good when urea contributes to build up 12 % RDP of the ration (Gould, 1969. However, scientific information regarding this effect in buffalo is limited. Therefore the present study was planned to determine the impact of varying level of RDP on ruminal characteristics, digestibility, blood pH, blood urea nitrogen (BUN and N balance in buffalo bulls.

    The present study was undertaken to examine whether the presence of antral follicles (AFs) affects the survival, growth and steroidogenesis of preantral follicles (PFs) and compare the maturation and developmental competence of buffalo oocytes derived from in vivo developed and in vitro cultured AFs. Two experiments were carried out. In experiment I, PFs (200-250 μm) were isolated and cultured with or without AFs (3-5 mm) in TCM-199 medium that contained 10% fetal bovine serum (FBS), 1% insulin transferin selenium (ITS), 20 ng/ml epidermal growth factor (EGF), 0.5 μg/ml follicle-stimulating hormone (FSH) and 100 ng/ml insulin-like growth factor (IGF)-I. In experiment II, in vitro developmental competence was compared for the cumulus-oocyte complexes (COCs) recovered from in vivo developed and in vitro cultured AFs. Survival, growth, development of antrum, accumulation of estradiol and progesterone was (P cultured with AFs. Developmental competence of both types of follicular oocytes did not differ significantly in terms of maturation and cleavage rate, but morula and blastocyst production rate were (P vitro cultured antral follicular oocytes. In conclusion, co-culture of PFs with AFs supports long-term survival and growth of buffalo PFs and this co-culture system plays a dual role for in vitro production of embryos as well as understanding the relationship between developing PFs and AFs.

    Oocytes from abattoir-derived bubaline (Bubalus bubalis) ovaries were subjected to IVM and IVF; the objective was to develop a pronuclear DNA microinjection technique to produce embryos expressing green fluorescent protein (GFP). The largest proportion (61.2%) of zygotes in which one (1 PN) or two pronuclei (2 PN) were visible was when centrifugation (14,000 x g for 15 min) was done 16 h after insemination. Centrifugation had no adverse effects on cleavage rate, development to morulae/blastocysts, and total cell number of embryos. Piercing the pronuclear but not the plasma membrane reduced (Pbuffer alone, which, in turn, were higher (Pbuffer containing 5 microg/mL DNA. The cleavage rate (39.2% vs. 34.8%) and proportion of cleaved embryos that developed to morulae/blastocysts (37.5% vs. 10.9%) were higher (P<0.05) for microinjected zygotes with 2 PN than for those with 1 PN. The cleavage rate and the proportion of cleaved embryos that developed to morulae and blastocysts were higher (P<0.05) following culture of microinjected zygotes in mCR2aa medium (40.7, 32.7, and 9.1%, respectively) compared to those for mSOFaa (33.3, 26.0, and 6.5%, respectively) or after culture in TCM-199+co-culture with buffalo oviductal epithelial cells (31.2, 25.0, and 4.5%, respectively). The proportion of embryos expressing GFP was higher (P<0.01) for 2 PN than for 1 PN zygotes (15.9% vs. 13.7%).

    Full Text Available Despite being successfully used to produce live offspring in many species, somatic cell nuclear transfer (NT has had a limited applicability due to very low (>1% live birth rate because of a high incidence of pregnancy failure, which is mainly due to placental dysfunction. Since this may be due to abnormalities in the trophectoderm (TE cell lineage, TE cells can be a model to understand the placental growth disorders seen after NT. We isolated and characterized buffalo TE cells from blastocysts produced by in vitro fertilization (TE-IVF and Hand-made cloning (TE-HMC, and compared their growth characteristics and gene expression, and developed a feeder-free culture system for their long-term culture. The TE-IVF cells were then used as donor cells to produce HMC embryos following which their developmental competence, quality, epigenetic status and gene expression were compared with those of HMC embryos produced using fetal or adult fibroblasts as donor cells. We found that although TE-HMC and TE-IVF cells have a similar capability to grow in culture, significant differences exist in gene expression levels between them and between IVF and HMC embryos from which they are derived, which may have a role in the placental abnormalities associated with NT pregnancies. Although TE cells can be used as donor cells for producing HMC blastocysts, their developmental competence and quality is lower than that of blastocysts produced from fetal or adult fibroblasts. The epigenetic status and expression level of many important genes is different in HMC blastocysts produced using TE cells or fetal or adult fibroblasts or those produced by IVF.

    Full Text Available Wild water buffaloes (Bubalus arnee are categorized as endangered on the IUCN Red List. With a global population of less than 4,000, the species has a very limited distribution spanning over less than 20,000 km2 in Nepal, India, Sri Lanka, Cambodia, Myanmar, Thailand and Bhutan. In Nepal, Koshi Tappu Wildlife Reserve was designated for wild Asian buffalo; this reserve contains approximately 219 individuals, although there is no precise information on the number of pure-bred wild buffalo. The conservation of wild buffalo is of global concern; there are numerous threats due to habitat fragmentation, as well as competition, hybridization, habitat overlap, disease and parasites transmitted by domestic livestock. The reserve provides an area of only 0.80 km2 per buffalo, which is insufficient maintaining a viable population of wild buffalo. It is therefore important to identify further potential habitat and to begin translocation of some of the individuals. A Wild Buffalo Conservation Alliance can play a key role in influencing conservation strategies by conducting detailed research including feasibility studies on translocation, developing awareness, holding workshops and preparing a conservation action plan. In this way the alliance can help to increase the number of wild buffaloes and to maintain a viable population of the species.

    2012-11-01

    Full Text Available The Asiatic Wild Water Buffalo Bubalus arnee is an endangered species restricted to South and Southeast Asia. Nepal’s only population survives in the Koshi Tappu Wildlife Reserve which is located on the floodplain of the Koshi River, a tributary of Ganga. This species is under threat due to high anthropogenic pressure ranging from habitat deterioration to hybridization with domestic buffalo. Yet, the population has grown from 63 in 1976 to 219 in 2009, despite the decline in the calf/cow ratio. The present study conducted in 2009 used the block count method. The count showed the presence of a backcrossed population of 74 in addition to the total of 219 individuals. At present, a number of conservation and livelihood interventions have been undertaken to safeguard the biodiversity, particularly the wild buffalo population in the Koshi Tappu Wildlife Reserve. The community-based sustainable management approach benefiting both conservation and livelihood of local people is necessary to ensure the long term conservation of the species

  2. Cytochrome b gene haplotypes characterize chromosomal lineages of anoa, the Sulawesi dwarf buffalo (Bovidae: Bubalus sp.).

    Partial mitochondrial cytochrome b gene sequences reveal two deeply differentiated mtDNA lineages in anoa dwarf buffaloes (Bubalus depressicornis) from the studbook herd in European zoos. Three matrilinear lineages of lowland anoas (depressicornis type) contributed three rather similar sequence haplotypes, but one remarkably distinct haplotype was observed exclusively in mountain anoas (quarlesi type) descended from one founder female. The carriers of the distinctive mtDNA haplotype were also distinguished by several chromosomal and phenotypic peculiarities too. The differentiation between the mtDNA lineages of anoa approached or even surpassed the genetic divergence between some uncontested species of wild cattle. The depth of this haplotype divergence in anoas is discussed against the background of the phylogenetic age of these paleoendemic inhabitants of a predator-free island refugium, Sulawesi, who are among the most plesiomorphic living bovines. The studbook breeding of captive anoas as a safeguard against extinction might profit from such population genetic markers. These cytochrome b gene sequences were unable to resolve the phylogeny of nine bovine taxa robustly, except the divergence of Bubalus, Synceros, Bison, and Bos (sensu lato) genera.

    Full Text Available Abstract Background Fluorescence of dyes bound to double-stranded PCR products has been utilized extensively in various real-time quantitative PCR applications, including post-amplification dissociation curve analysis, or differentiation of amplicon length or sequence composition. Despite the current era of whole-genome sequencing, mapping tools such as radiation hybrid DNA panels remain useful aids for sequence assembly, focused resequencing efforts, and for building physical maps of species that have not yet been sequenced. For placement of specific, individual genes or markers on a map, low-throughput methods remain commonplace. Typically, PCR amplification of DNA from each panel cell line is followed by gel electrophoresis and scoring of each clone for the presence or absence of PCR product. To improve sensitivity and efficiency of radiation hybrid panel analysis in comparison to gel-based methods, we adapted fluorescence-based real-time PCR and dissociation curve analysis for use as a novel scoring method. Results As proof of principle for this dissociation curve method, we generated new maps of river buffalo (Bubalus bubalis chromosome 20 by both dissociation curve analysis and conventional marker scoring. We also obtained sequence data to augment dissociation curve results. Few genes have been previously mapped to buffalo chromosome 20, and sequence detail is limited, so 65 markers were screened from the orthologous chromosome of domestic cattle. Thirty bovine markers (46% were suitable as cross-species markers for dissociation curve analysis in the buffalo radiation hybrid panel under a standard protocol, compared to 25 markers suitable for conventional typing. Computational analysis placed 27 markers on a chromosome map generated by the new method, while the gel-based approach produced only 20 mapped markers. Among 19 markers common to both maps, the marker order on the map was maintained perfectly. Conclusion Dissociation curve

    Full Text Available Aim: Present study was carried out to sequence and phylogenetic analysis of CXCR2 gene of Murrah buffalo. Materials and Methods: For the present investigation, from a group of forty eight Murrah buffaloes (Bubalus bubalis, blood samples were collected randomly from eight animals, out of which four were healthy and four were mastitic. Results: The amplification of Interleukin-8B (IL-8B receptor gene target sequence was carried out using the primer pair in an optimized polymerase chain reaction. Partial sequencing of IL-8B receptor gene of Bubalus bubalis (Murrah has been done successfully. The sequences of IL-8B receptor gene showed 99% homology to that of Bos indicus × Bos taurus, 98% to that of Bos taurus, 97% to that of Ovis aries, 93% to that of Sus scrofa, 92% to that of Equus caballus and 90% to that of Felis catus. Conclusion: From the present study it can be concluded that the PCR amplification procedure for target region of IL-8B receptor gene yielding 459 bp products has been standardized, which yielded consistent and specific amplification. Amplification of partial IL-8B receptor gene (exon 2- 459 bp using self designed primers specific for cattle ortholog sequence signifies that the locus is conserved in cattle and buffaloes. In phylogenetic tree, the target sequence of IL-8B receptor gene of Bubalus bubalis were found to be more closely related to Bos indicus × Bos Taurus and Bos taurus than to Ovis aries and Sus scrofa.

    Full Text Available The objective of this work was to estimate the correlations among measurements taken in vivo with ultrasound equipment with some carcass traits measured after slaughter. Twenty eight Mediterranean bulls, with average shrunk body weight of 330 kg and 14 months of age, were fed by 120 days with high concentrate diets. The shrunk body weight, the ribeye area (REAU, the back fat thickness (FTU over the Longissimus dorsi muscle between 12ª and 13ª ribs and rump fat (EGP8U, were measured at 28 days intervals. Real-time ultrasound equipment Piemedical Scanner 200 VET, with 18 cm linear array transducer was utilized. After the slaughter, the hot carcass weight (PCQ and the kidney, pelvic and inguinal fat (GRPI were weighted and the dressing percentage (DP calculated. After 24 hours of cooling the ribeye area (REAC, backfat thickness (FTC and rump fat (EGP8C were measured. Both the REAC, FTC and EGP8C were underestimated by ultrasound measurements. The Pearson correlation coefficients for ribeye area, backfat thickness and rump fat measured in the carcass and with ultrasound, were 0.96, 0.99 and 0.91, respectively. The coefficient between DP and REAU was 0.47; 0.45 between DP and REAC, 0.56 between DP and FTU and 0.58 between DP and FTC. DP presented a 0.59 correlation coefficient with EGP8U. The Spearman correlation was estimated between REAU and REAC, FTU and FTC, EGP8U and EGP8C, and the values were 0.96, 0.99 and 0.91 , respectively. The ultrasound measures could be used to estimate carcass traits in buffaloes with good accuracy.

    Pasteurella multocida serotype A:3 has been mostly implicated in pneumonic pasteurellosis in ruminants. In contrast, our previous studies have reported that both serotypes A:1 and A:3 were responsible for respiratory diseases in cattle and buffaloes. However, the pathology and pathogenesis of P. multocida serotype A:1 (Pm A:1) infection have not been studied in ruminants. In the present study, 12- to 15-week-old buffalo calves (Bubalus bubalis) infected by Pm A:1 had fibrinous and suppurative bronchopneumonia with focal areas of coagulation necrosis typical of pneumonic pasteurellosis. For the first time, this study reports the lung pathology and pathogenecity of Pm A:1 infection in calves.

    Full Text Available The aim of this study was to determine if qualitative and quantitative differences exist in energy substrates and ionic components of buffalo cow oviductal fluid during dioestrus, pre-ovulatory and ovulatory phases of the oestrous cycle. Ten multiparous Italian Mediterranean Buffalo (Bubalus Bubalis cows at 15 days in milk were used. Cannulation of oviduct was performed as previously described by Kavanaugh et al.(1992 for cattle, adapting the technique to the smaller dimension of buffalo reproductive tract. We evaluated daily secretion rates, energy substrates and ions concentration during the three phases. Oviductal fluid secretion rates (ml/24h and glucose concentration were significantly greater in the ovulatory phase (P<0.01 and in the pre-ovulatory phase (P<0.05 than in dioestrus. No significant differences were detected between oestrous phases for the other parameters analyzed.

    The pharmacokinetics of tylosin were compared in cattle (Bos taurus) and buffaloes (Bubalus bubalis). Six animals received each a single dose of 10 mg/kg of tylosin tartrate by the intramuscular route. The serum concentration (Cmax) and the volume of distribution (Vd) presented significant differences between the two species. Cmax was 0.40 +/- 0.046 microg/ml for buffaloes and 0.64 +/- 0.068 microg/ml for cattle. Vd was 1.91 +/- 0.12 L/kg and 1.33 +/- 0.09 L/kg for buffaloes and cattle, respectively. However, as the present study did not show considerable differences in the pharmacokinetics of tylosin in buffaloes and cattle, similar dosage regimes of this drug can be recommended for both species.

    Dairy product authenticity is presently a subject of great concern to food authorities, as the incorrect labelling of foodstuffs can present a commercial fraud. Many consumers are concerned about dairy products they eat and accurate labelling is important to inform consumer choice. Thus, the detection of milk species is important in cheese making, not only with regards to accurate consumer information and legal aspects (concerned with labeling and guarantee requirements) but also to medical requirements, food allergies or religious practices. Specific primers and Taq Man-MGB probe were designed according to highly conserved sequence of mitochondrial cytochrome b (Cytb) gene of buffalo (Bubalus bubalus) to develop a Real-time fluorescence polymerase chain reaction (Real-time PCR) assay for rapid detection of buffalo ingrediens. The primers and probes could specific identify 5 kinds of buffalo with 47 kinds of samples. The detection limit of the method was 0.001 ng/μL DNA concentration and 0.01 %(W/W) buffalo milk. The commercial samples were detected by Real-time PCR and the detection results showed that buffalo ingredients were detected well. All the results confirm that the Real-time PCR assay is a sensitive and specific method for the detection of buffalo materials in dairy products.%水牛奶制品因其良好的营养功效备受国内外消费者的青睐,而在国内外,乳制品掺假行为,却常有发生.我国作为水牛奶酪等乳制品的进口国,迫切需要一种准确的水牛成分的检测方法,来避免这种掺假行为对我国的进出口贸易造成损失.根据水牛Bubalus bubalus)线粒体细胞色素b(Cytb)基因的保守序列,设计一对特异性引物和TaqMan-MGB探针,建立了水牛乳成分的实时荧光PCR检测方法.运用实时荧光PCR方法对5种乳水牛样品和47种常见的非水牛动植物样品进行检测,5种水牛乳样品均产生荧光信号,其余非水牛样品均不产生荧光信号,表明该检测方

    This study presents the first description of Bovine herpesvirus 6 (BoHV-6) that was isolated from buffaloes of Amazon region in Brazil. Phylogenetic analysis showed that the BoHV-6 Brazilian strains clustered with the sequence of BoHV-6 from elsewhere available at the GenBank. It was observed in some buffaloes with lymphoproliferative disease in one herd, thus the animals were also tested for Bovine leukemia virus (BLV), which has been associated to lymphoma in bovines. All animals were negative to BLV. These results indicate that BoHV-6 is present in buffaloes in Brazil, but the importance and impact of this infection and its association with any illness is still undefined.

    Full Text Available Neuroendocrine cells or paraneurons are cytotypes producing biogenic amines and/or hormonal peptides, scattered in the glandular and lining epithelia of the body. In this study the presence of chromogranin A-, serotonin- and somatostatin-immunoreactive neuroendocrine cells has been described immunohistochemically in the urethro- prostatic complex and female urethra of subjects of the buffalo Bubalus bubalis. The chromogranin A- containing neuroendocrine cells resulted the most numerous cytotype, the serotonin- containing ones the most irregular in shape for the presence of dendritic-like cytoplasmic extensions and the somatostatin- containing the rarest. The role played by the amine serotonin in the genital tract has been related to the determinism of sexual climax and to the contraction of smooth muscle. The function played by the neuroendocrine genital somatostatin is unknown. Analogically to what described for the same gastrointestinal hormone, it could inhibit both exocrine and endocrine secretions.

    Prion protein, encoded by the prion protein gene (PRNP), plays a crucial role in the pathogenesis of transmissible spongiform encephalopathies (TSEs). Several polymorphisms within the PRNP are known to be associated with influencing bovine spongiform encephalopathy (BSE) susceptibility in cattle, namely two insertion/deletion (indel) polymorphisms (a 23-bp indel in the putative promoter and a 12-bp indel in intron 1), the number of octapeptide repeats (octarepeats) present in coding sequence (CDS) and amino acid polymorphisms. The domestic buffaloes, Bubalus bubalis, are a ruminant involved in various aspects of agriculture. It is of interest to ask whether the PRNP polymorphisms differ between cattle and buffalo. In this study, we analyzed the previously reported polymorphisms associated with BSE susceptibility in Chinese buffalo breeds, and compared these polymorphisms in cattle with BSE, healthy cattle and buffalo by pooling data from the literature. Our analysis revealed three significant findings in buffalo: 1) extraordinarily low deletion allele frequencies of the 23- and 12-bp indel polymorphisms; 2) significantly low allelic frequencies of six octarepeats in CDS and 3) the presence of S4R, A16V, P54S, G108S, V123M, S154N and F257L substitutions in buffalo CDSs. Sequence alignments comparing the buffalo coding sequence to other species were analyzed using the McDonald-Kreitman test to reveal five groups (Bison bonasus, Bos indicus, Bos gaurus, Boselaphus tragocamelus, Syncerus caffer caffer) with significantly divergent non-synonymous substitutions from buffalo, suggesting potential divergence of buffalo PRNP and others. To the best of our knowledge this is the first study of PRNP polymorphisms associated with BSE susceptibility in Chinese buffalo. Our findings have provided evidence that buffaloes have a unique genetic background in the PRNP gene in comparison with cattle.

    Full Text Available Buffalo (Bubalus bubalis livestock for mozzarella cheese production plays a fundamental role in the economy of southern Italy. European and Italian regulations consider nitrogen content in buffalo manure to be the same as that of cattle manure. This study aimed to assess whether this assumption is true. The first aim of the study was to assess nitrogen content in buffalo manure. Samples were taken from 35 farms to analyse nitrogen and phosphorous concentration in the manure. Analysis confirmed a lower nitrogen concentration (2% in buffalo manure. A secondary aim of the study was to evaluate whether manure application techniques that are apparently less suitable, e.g. splash plate spreader, could be feasible. The cost of different methods of land application of manure and their characteristics were evaluated on the basis of one operational cycle. Considering losses for volatilisation, and taking into account cost assessment, the immediate incorporation of buffalo manure (nitrogen content 2% is a suitable method of ammonia volatilisation. However, it is expensive and involves high fuel consumption in relation to the environmental benefit.

    Full Text Available Bubalus bubalis (Ruminantia: Bovidae, Bovinae is an economically important animal of many Asian countries, making significant contribution to milk and meat production. Sub clinical infection of the reproductive tract is one of the important causes for reduced reproductive efficiency in dairy herd of buffaloes. Antimicrobial peptides are component of innate immune system which helps in augmenting the resistance to infection at epithelial surfaces e.g reproductive tract epithelium. In this study we have identified a ß-defensin called Lingual Antimicrobial Peptide (LAP in buffalo reproductive tract. Interestingly the gene was 100 % identical to the LAP isolated from the tongue epithelium of Bos taurus. The 195 bp cDNA of LAP codes for 64 amino acids and of which 50% are cationic amino acids. Phylogenetic studies indicate that LAP of reproductive epithelium of buffalo is different from other beta defensins isolated from the various tissues of same species, but all beta defensin were found to have the same progenitor gene. It is concluded that buffalo reproductive tract epithelium lining contains LAP. [Vet. World 2011; 4(3.000: 120-123

    Recent strong selection for dairy traits in water buffalo has been associated with higher levels of inbreeding, leading to an increase in the prevalence of genetic diseases such as transverse hemimelia (TH), a congenital developmental abnormality characterized by absence of a variable distal portion of the hindlimbs. Limited genomic resources available for water buffalo required an original approach to identify genetic variants associated with the disease. The genomes of 4 bilateral and 7 unilateral affected cases and 14 controls were sequenced. A concordance analysis of SNPs and INDELs requiring homozygosity unique to all unilateral and bilateral cases revealed two genes, WNT7A and SMARCA4, known to play a role in embryonic hindlimb development. Additionally, SNP alleles in NOTCH1 and RARB were homozygous exclusively in the bilateral cases, suggesting an oligogenic mode of inheritance. Homozygosity mapping by whole genome de novo assembly also supported oligogenic inheritance; implicating 13 genes involved in hindlimb development in bilateral cases and 11 in unilateral cases. A genome-wide association study (GWAS) predicted additional modifier genes. Although our data show a complex inheritance of TH, we predict that homozygous variants in WNT7A and SMARCA4 are necessary for expression of TH and selection against these variants should eradicate TH.

    In the present study a thiol proteinase inhibitor was isolated from buffalo kidney making use of ammonium sulphate precipitation and gel filtration chromatography on Sephacryl S-100HR column. Purified inhibitor is homogeneous as it displayed a single band in gel electrophoresis both under reducing and non-reducing environment and is of 65KDa as revealed by gel filtration and SDS PAGE. Kinetic studies revealed the presence of reversible accompanied with competitive mode of inhibition; showing maximum efficacy against papain (Ki=2.90×10(-4)). It was maximally active at pH 8.0 and was stable for a period of 30, 60 and 90 days at 37, 4 and -20°C respectively. Immunological studies confirmed its purity of epitopes as a single precipitin line is obtained in immunodiffusion. N-terminal analysis revealed that it shared a good homology with mouse kidney cystatin as well as with Human Cys C and Cys E thereby advocating its use as a model for various human oriented studies which targets how the kidney cystatin level varies in accordance with various drugs that are currently being used as a target for variety of diseases.

    Full Text Available Thirteen (14.4% out of 90 Murrah buffaloes (Bubalus bubalis became ill after con-sumption of Senecio brasiliensis, and 11 (12.2% of them died. The buffaloes were kept in a highly Senecio brasiliensis infested area. The poisoning occurred in June-August 2006 on a farm in the county of Nova Prata, Rio Grande do Sul, southern Brazil. Clinical signs included weakness, apathy, progressive weight loss, permanent decubitus, and diarrhea. Necropsy was performed in 2 of the 11 buffaloes that died. The pathological findings were typical of poisoning by pyrrolizidine alkaloids. High infestation of pastures with S. brasiliensis, severe drought, and consequent starvation were the main epidemiological factors associated with the poisoning here described.Descreve-se a ocorrência de um surto de intoxicação espontânea por Senecio brasiliensis em búfalos Murrah (Bubalus bubalis em uma propriedade localizada no município de Nova Prata, Estado do Rio Grande do Sul, no período de junho a agosto de 2006. De um total de 90 búfalos, 13 adoeceram e 11 morreram. Os animais eram mantidos em áreas de pastoreio altamente infestadas por S. brasiliensis. Os principais sinais clínicos relatados foram letargia, apatia, emagrecimento progressivo, diarréia e decúbito permanente. Necropsia foi feita em dois dos 11 animais mortos. As lesões foram características de intoxicações por alcalóides pirrolizidínicos. A grande quantidade da planta, forte estiagem e desnutrição conseqüente foram os principais achados epidemiológicos associados com a mortalidade.

    In the present study, the effect of heat stress, which is commonly observed in the animals of Upper Egypt area in summer, as well as the effect of antioxidant treatment as a thermo-protective was examined. In this study, the animals (n = 120) were divided into winter group (n = 40, bred during winter) and summer group (n = 80, bred during summer) as well as, animals in the summer group were divided into first subgroup animals (n = 40) and injected with Viteselen intramuscularly (15 ml) twice weekly for 10 weeks and second subgroup animals (n = 40) were not treated (as control). Serum levels of progesterone (P4), oestradiol (E2), cortisol, superoxide dismutase (SOD), lipid peroxidase (LPO) and nitric oxide (NO) were measured. The pregnancy rate of all animals was detected rectally. The levels of oestradiol and the activity of the antioxidant SOD were decreased in serum of animals in behavioural oestrus during summer as compared with those in winter. During the same time period the levels of oxidants such as LPO and NO were increased in the serum of animals again in the phase of oestrus. In another group of animals treated by intramuscular injection with 15 ml viteselen (antioxidant) twice weekly for 6 weeks during hot months, the activities of serum SOD showed an increase and the levels of oxidants and cortisol decreased. Moreover, the levels of oestradiol were increased during the oestrous behaviour. The pregnancy rate was decreased in animals under heat stress and the pregnancy rate was enhanced dramatically when these animals received antioxidants during the heat stress. This means that the heat-stress in Upper Egypt may affect the fertility of animals and pregnancy rate and this effect may be through an increased production of free radicals and decreased production of antioxidants as well as increased levels of cortisol. Treatment of animals or supplementation with antioxidants before the beginning of months of heat-stress and also during the stress period may correct the infertility due to heat-stress through the decrease in cortisol secretion and a decrease in the oxidative stress. These results resulted in an increase in pregnancy rate in treated animals.

    The Western Forest Complex (WEFCOM) of Thailand is comprised of many protected areas and has one of the highest wildlife populations in the country. Populations of wildlife in the WEFCOM have decreased dramatically over recent years. Rapid economic development has resulted in the conversion of forest into agricultural and pastoral land, which has directly and indirectly impacted the wildlife community. This research aimed to evaluate populations of domesticated cattle (Bos indicus) and buffalo (Bubalus bubalis) in the WEFCOM and their possible impacts on the wildlife community. Domesticated cattle and buffalo keepers from 1561 (or 3.3%) of houses in and near WEFCOM were interviewed. The average number of animals per household was 15.6 cattle and 8.5 buffalo. Most villagers released domesticated cattle and buffalo to forage in the protected areas. This tended to have a high impact on the wildlife community in Huai Kha Khaeng Wildlife Sanctuary and Tungyai Naresuan Wildlife Sanctuary. The least impacted areas were Luam Khlong Ngu National Park, Thong Pha Phum National Park and Chaleam Ratanakosin National Park. With a high risk to the wildlife community, law enforcement should be used in combination with a certain level of co-management with local communities.

    Full Text Available Approximately 250 000 water buffalo (Bubalus bubalis live in the Campania region of southern Italy where the breeding of this species is very popular. Of these animals, almost 150 000 are concentrated in the Caserta province where the prevalence of Brucella abortus in this species represents approximately 20% at herd level. The Italian brucellosis eradication programme provides a slaughter and vaccination strategy for this province. B. abortus strain RB51 (RB51 has become the official vaccine for the prevention of brucellosis in cattle in several countries. The aim of this study was to evaluate the efficacy of RB51 in water buffalo compared to the B. abortus S19 vaccine (S19. The study was performed in accordance with a protocol described in mice. Female buffalo aged five months were inoculated. Five received a RB51 dosage on two occasions that was three times greater than that approved for use in cattle and a booster after one month, five received B. abortus S19 vaccine at the standard dosage and three controls received a phosphate buffer solution. Buffalo were then challenged with a virulent B. abortus strain 544 thirty days post vaccination. Antibodies that developed in the five animals vaccinated with RB51 were not detected by the Rose Bengal test or complement fixation test (CFT and were also tested by CFT prepared with RB51 antigen. After culling, B. abortus was cultured from the spleen, retropharyngeal and supra-mammary lymph nodes. A statistical evaluation was performed to assess the immunogenicity values obtained in buffalo vaccinated with S19, compared to those obtained in buffalo vaccinated with the RB51 vaccine and in the unvaccinated control group.

The tests for docility, reaction to a novel object, squeeze cage and social isolation were applied individually with 12 calves and their 12 mothers. Both calves and their mothers responded to all tests with a variety of behaviors. The tests that elicited the larger number of behaviors were the squeeze cage and the novel object. There were large individual differences (coefficients of variation of 32-51% in the scores for all tests for calves and adults. The individual scores for the tests of isolation and novel object were significantly correlated for calves (rs = 0.66, P< 0.01 and adults (rs = 0.76, P< 0.01. Using the criteria of sensitivity (range of individual differences, responsiveness and applicability, the squeeze cage test and the isolation test seem well suited for water buffaloes.

    This study determined the carcass composition of Lao indigenous buffalo (Bubalus bubalis) and cattle (Bos indicus), then examined trends in bovine meat marketing following review of records of beef production and prices in the two major cities of Luang Prabang (LPB) and Xieng Khoung (XK) provinces in northern Laos. Samples from 41 buffalo and 81 cattle (n = 122) were collected from animals slaughtered in May-June 2014, with live weights, carcass weights and other carcass-related variables collected. The animals were classified into four age cohort groups (4, 4-6 and >6 years) with quantitative and dichotomous qualitative traits determined. There were significant differences in buffalo and cattle predicted mean carcass weights between age classification categories (p = 0.003 and 0.001) but not in dressing percentages (p = 0.1 and 0.1). The carcass weight of buffalo was 104 (±23.1)-176 (±12.0) kg compared to 65 (±8.7)-84 (±6.5) kg of cattle, with dressing percentages of 37-40 and 39-42 %, respectively. Despite an average bovine meat price increase of 42-48 % between 2011 and 2013, there was a reduction in the numbers of large ruminants slaughtered in the surveyed cities of LPB (11 %) and XK (7 %), with bovine meat availability per person of 5.2-6.6 kg (LPB) and 3.0-3.8 kg (XK). Improving the sustainability of the bovine meat supply in Laos requires a systems approach involving improvements to animal health and production, livestock marketing, plus the critical development of improved slaughterhouse facilities enabling a meat-processing sector to emerge. This development pathway is of particular importance for building the capacity of Laos to reduce food insecurity and alleviate the poverty of its largely rural smallholder community.

    Full Text Available The effect of dietary supplementation with Enterococcus faecium strain SF68 on growth performance, faecal consistency and in vivo digestibility in buffalo (Bubalus bubalis calves was evaluated. Forty calves were randomly assigned at 10 d of age to one of four treatments: (A milk replacer with no additive, (B milk replacer supplemented with 0.17 g/l of viable (2 x l09 cfu/g E. faecium bacteria daily for 3 days with an interval of 7 days throughout 11 weeks, (C milk replacer supplemented with E. faecium daily for 4 weeks, (D milk replacer supplemented with E. faecium daily for 11 weeks. A total mixed ration was offered ad libitum from 5th week of the experimental period. Faecal score was significantly better in E. faecium-treated calves than control ones. The use of E. faecium had no effect on average daily gain at any stage, total body weight (BW gain, dry matter intake or total tract digestibility. Therefore, E. faecium supplementation may be able to act favourably on the health of the gastrointestinal tract.

    Full Text Available Oestrus synchronization may be used to overcome poor oestrus expression and seasonality of breeding in buffalo (Bubalus bubalis. The present work was conducted to compare the efficiency of an oestrus synchronization protocol “ovsynch” in Nili Ravi buffalo during peak (n=8 and low breeding seasons (n=11 by determining luteinizing hormone (LH peak and progesterone (P4 rise in blood plasma using ELISA. Buffaloes were administered gonadotropin releasing hormone (GnRH analogue (50 µg lecirelin; day 0 followed by prostaglandinF2α (PGF2α analogue (150 µg cloprostenol; day 7 and again GnRH analogue at 36 hours after PGF2α. Blood sampling for LH was started 12 h after PGF2α injection and done at 3 h interval up to 108 h. An animal was considered to have responded to ovsynch protocol if it showed LH peak within 48 h after PGF2α injection (and within 3-6 h after second GnRH injection and showed a P4 concentration of >2.0 ng/ml on day 18 after the 1st GnRH injection. 87.5% animals showed positive response to ovsynch protocol in term of oestrus and ovulation synchronization during the peak season as assessed by LH peak and P4 level while only 36.36 % animals responded to synchronization treatment during low breeding season (P<0.05. The LH peak in responsive animals was 11.48±1.98 and 10.38±1.77 ng/ml in peak and low breeding season respectively. It is concluded that ovsynch protocol in buffaloes resulted in a significantly better response during peak breeding season as compared to that in low breeding season.

    Full Text Available Abstract Background Salmonellosis in water buffalo (Bubalus bubalis calves is a widespread disease characterized by severe gastrointestinal lesions, profuse diarrhea and severe dehydration, occasionally exhibiting a systemic course. Several Salmonella serovars seem to be able to infect water buffalo, but Salmonella isolates collected from this animal species have been poorly characterized. In the present study, the prevalence of Salmonella spp. in water buffalo calves affected by lethal gastroenteritis was assessed, and a polyphasic characterization of isolated strains of S. Typhimurium was performed. Results The microbiological analysis of the intestinal contents obtained from 248 water buffalo calves affected by lethal gastroenteritis exhibited a significant prevalence of Salmonella spp. (25%, characterized by different serovars, most frequently Typhimurium (21%, Muenster (11%, and Give (11%. The 13 S. Typhimurium isolates were all associated with enterocolitis characterized by severe damage of the intestine, and only sporadically isolated with another possible causative agent responsible for gastroenteritis, such as Cryptosporidium spp., Rotavirus or Clostridium perfringens. Other Salmonella isolates were mostly isolated from minor intestinal lesions, and often (78% of cases isolated with other microorganisms, mainly toxinogenic Escherichia coli (35%, Cryptosporidium spp. (20% and Rotavirus (10%. The S. Typhimurium strains were characterized by phage typing and further genotyped by polymerase chain reaction (PCR detection of 24 virulence genes. The isolates exhibited nine different phage types and 10 different genetic profiles. Three monophasic S. Typhimurium (B:4,12:i:- isolates were also found and characterized, displaying three different phage types and three different virulotypes. The molecular characterization was extended to the 7 S. Muenster and 7 S. Give isolates collected, indicating the existence of different virulotypes also within

    The aim of this study was to evaluate the effect of an Ovum Pick-up (OPU) treatment carried out for 9 months in buffalo (Bubalus bubalis) species. Eight pluriparous non-lactating buffalo cows underwent OPU for 9 months. Recovered cumulus enclosed oocytes (COCs) were classified and COCs suitable for in vitro embryo production (IVEP) were in vitro matured (IVM), fertilized (IVF) and cultured (IVC) to the blastocyst (Bl) stage. Animals were monitored for a total period of 270 days, but at the summer solstice, follicular turnover decreased and at the 68-day of the trial, we decided to increase the OPU sampling interval from 3-4 to 7 days. It was therefore possible to distinguish two phases: a first phase (18 sessions), during which OPU was carried out twice weekly and a second phase (16 sessions) during which OPU sessions were performed weekly. This reduction did not modify the percentage of good quality COCs, while the incidence of grade D COCs decreased (P<0.01). Furthermore, embryo production was higher in the second phase, either if embryos were calculated on the total recovered COCs (8.3% vs. 21.4%; P<0.01) and on grade A+B COCs (13.0% vs. 32.1%; P<0.01), that supposedly should have given similar blastocyst yield. During the total period of the trial it was possible to distinguish a first period of 6 months (34 sessions) characterized by blastocyst production (0.36 blastocyst/buffalo/session), followed by an unproductive period of 3 months (12 sessions), during which embryos were not produced. During the first 6 months a higher (P<0.01) number of follicles (5.06 vs. 3.71), small follicles (3.38 vs. 2.07), total COCs (2.58 vs. 1.56) and good quality (A+B) COCs (1.51 vs. 0.94) per subject/session were recorded compared to the last 3 months. No Blastocyst were produced during the second period, even if the percentage of grade A+B COCs was similar to that recorded during the first period. In conclusion, buffalo cows submitted to repeated OPU sampling for a 9-month

    The fossil and extant faunas of Sulawesi, the largest island within the Wallacea biogeographic region, exhibit a high degree of endemism. The lowland anoa Bubalus depressicornis and the mountain anoa Bubalus quarlesi, two closely-related dwarfed buffaloes, are among the most peculiar endemic mammals of the region. Here, I describe a new species, Bubalus grovesi, from the Late Pleistocene/Holocene of South Sulawesi and I give a revised diagnosis of Anoa. Bubalus grovesi sp. nov. differs from all previously described Bubalus in both the size and proportions of the skeleton and in possessing a unique combination of discrete character states. Body mass estimates suggest an average mass of 117 kg for Bubalus grovesi sp. nov. and a body size reduction of about 90% with respect to a typical water buffalo. A comprehensive overview of body mass estimates of dwarfed buffaloes and differences in their dental and postcranial features is included. Finally, new evidence on the taxonomy and island dwarfing of the anoas and available data from different disciplines are used to discuss the timing and mode of their evolution. The representatives of the subgenus Anoa would be dwarfed forms of the Asian water buffalo that arose following dispersal to Sulawesi during the Middle/Late Pleistocene.

    Embryonic stem (ES) cells derived from mammalian embryos have the ability to form any terminally differentiated cell of the body. We herein describe production of parthenogenetic buffalo (Bubalus Bubalis) blastocysts and subsequent isolation of an ES cell line. Established parthenogenetic ES (PGES) cells exhibited diploid karyotype and high telomerase activity. PGES cells showed remarkable long-term proliferative capacity providing the possibility for unlimited expansion in culture. Furthermore, these cells expressed key ES cell-specific markers defined for primate species including stage-specific embryonic antigen-4 (SSEA-4), tumor rejection antigen-1-81 (TRA-1-81), and octamer-binding transcription factor 4 (Oct-4). In vitro, in the absence of a feeder layer, cells readily formed embryoid bodies (EBs). When cultured for an extended period of time, EBs spontaneously differentiated into derivatives of three embryonic germ layers as detected by PCR for ectodermal (nestin, oligodendrocytes, and tubulin), mesodermal (scleraxis, alpha-skeletal actin, collagen II, and osteocalcin) and endodermal markers (insulin and alpha-fetoprotein). Differentiation of PGES cells toward chondrocyte lineage was directed by supplementing serum-containing media with ascorbic acid, beta-glycerophosphate, and dexamethasone. Moreover, when PGES cells were injected into nude mice, teratomas with derivatives representing all three embryonic germ layers were produced. Our results suggest that the cell line isolated from a parthenogenetic blastocyst holds properties of ES cells, and can be used as an in vitro model to study the effects of imprinting on cell differentiation and as an a invaluable material for extensive molecular studies on imprinted genes.

    This report puts on record production of the first viable calf following ovum pick-up in vitro embryo production (OPU-IVEP) technique in buffalo (Bubalus bubalis) in India. A total of 313 transvaginal OPU sessions were performed in six elite Murrah buffaloes and 1 171 follicles were aspirated. From these follicles, a total of 729 immature oocytes were recovered. The recovered oocytes were graded as A (59, 8.1%), B (111, 15.2%), C (293, 40.2%) and D (262, 35.9%) following standard procedures. Maturable grade oocytes (A, B, and C; 473, 68.9%) were subjected to in vitro maturation in Medium 199 supplemented with 10% FBS, 0.5 μg/mL FSH, 10 IU/mL LH, 1 μg/mL estradiol-17β, 20 ng/mL EGF and 50 μM cysteamine in CO2 incubator at 39 ℃ temperature, 5%CO2 and high humidity. The matured oocytes (427 out of 473; 90.3%) were co-incubated with 1x106/mL buffalo sperms in modified synthetic oviductal fluid (mSOF) containing 10 ng/mL heparin for 22 hrs for in vitro fertilization. After fertilization the presumptive zygotes were stripped off of remaining cumulus cells and cultured in mSOF for 7 days to study embryonic development. A total of 278 (65.1%) oocytes cleaved after 24-36 hrs of fertilization. Out of the cleaved oocytes, 249 (89.6%), 216 (77.7%), 167 (60.1%), 139 (50.0%) and 73 (26.3%) developed up to 4-cell, 8-cell, 16-cell, morula, and blastocyst stages, respectively. A total of 29 embryos were transferred into 27 synchronized recipient buffaloes. Two of these buffaloes were found pregnant at 90 days. One of them aborted at 4.5 months of gestation (male fetus) and the other gave birth to a live male calf weighing 25 kg. Currently, the calf is normal and has attained the age of 4.5 years.

Macroscopicamente havia múltiplos tumores enegrecidos no músculo esquelético, pulmões, linfonodos, saco pericárdio, cápsula renal, mediastino e pleura. Microscopicamente foram observadas células epitelióides poliédricas dispostas em ninhos sólidos ou fascículos entrelaçados sustentadas por um estroma colagenoso fino e esparso. O citoplasma era eosinofílico e por vezes continham quantidades variáveis de pigmento de melanina. A taxa de mitose foi baixa. Na imuno-histoquímica houve imunomarcação positiva utilizando anticorpo anti-tirosinase, anti-Melan-A, anti-vimentina, anti-proteína S-100 e antineurofilamento. É possível que o polimorfismo relacionado com o gene da pigmentação em búfalos albinos tenha contribuído para o maior risco de desenvolvimento de melanomas, como foi sugerido em humanos.

    This study was designed to determine effect of various plant protein sources in high-quality feed block (HQFB) on feed intake, rumen fermentation, and microbial population in swamp buffalo. Four rumen-fistulated swamp buffaloes (Bubalus bubalis) were randomly assigned according to a 4 × 4 Latin square design. Four kinds of plant protein sources (coarse rice bran (CRB), cassava hay (CH), Phaseolus calcaratus hay, and mulberry hay (MH)) were mixed in the HQFB. HQFBs were allowed to be licked at free choice, and urea-lime-treated rice straw (ULRS) were fed ad libitum. It was found that bacterial population and fungal zoospores in CH-fed group tended to be higher than those in other groups. Moreover, protozoal population in CH, P. calcaratus hay, and MH were lower than those in CRB supplemented group (P < 0.05). Cellulolytic bacterial population was highest in CH-fed group while proteolytic bacteria population was highest in P. calcaratus hay-fed group (P < 0.05). CH-fed group had higher ULRS intake than those in other groups (P < 0.05). Nutrient digestibility of CP, NDF, and ADF in CH-fed group was significantly higher than those in other groups (P < 0.05). Total VFA was highest in CH-fed group (P < 0.05). N absorption was highest in CH-fed group (P < 0.05). Based on this study, it could be concluded that cassava hay, P. calcaratus hay, and mulberry hay are potential to be used as protein sources in the HQFBs especially cassava hay.

    Aboriginal land managers have observed that feral Asian water buffalo (Bubalis bubalis Lydekker) are threatening the ecological and cultural integrity of perennial freshwater sources in Arnhem Land, Australia. Here we present collaborative research between the Aboriginal Rangers from Warddeken Land Management Limited and Western scientists which quantified the ground-level impacts of buffalo on seven perennial freshwater springs of the Arnhem Plateau. A secondary aim was to build the capacity of Aboriginal Rangers to self-monitor and evaluate the ecological outcomes of their land management activities. Sites with high buffalo abundance had significantly different ground, ground cover, and water quality attributes compared to sites with low buffalo abundance. The low buffalo abundance sites were characterized by tall herbaceous vegetation and flat ground, whereas wallows, bare ground, and short ungrazed grasses were indicators of sites with high buffalo abundance. Water turbidity was greater when buffalo abundance was high. The newly acquired monitoring skills and derived indicators of buffalo damage will be used by Aboriginal Rangers to assess the ecological outcomes of their future buffalo control efforts on the Arnhem Plateau.

Foram utilizados quatro búfalos com três repetições por animal e por região. No protocolo 1, foi utilizada a técnica do fenol-clorofórmio e no protocolo 2, a técnica de extração com CTAB. O protocolo 2 apresentou maior média de concentração de DNA para as amostras de pelos. Em relação ao local de retirada dos pelos, não foram encontradas diferenças significativas, porém nota-se que a região da testa dos animais apresentou maior concentração de DNA quando extraído com CTAB. Com relação à praticidade de utilização dos dois métodos avaliados, o protocolo 2, além de ter apresentado maior concentração de DNA, apresentou menor tempo de execução, 3h 50 min., além de evitar a utilização de mais um reagente tóxico, como é o caso do fenol. Por esse motivo, sugere-se que a coleta seja efetuada na região da testa, levando-se em consideração a praticidade e a acessibilidade aos pelos e sugere-se também a aplicação do protocolo de extração de DNA com CTAB, pela praticidade e pelo menor tempo de execução.The objective of this paper was to compare two different protocols for DNA extraction from buffalo (Bubalus bubalis fur.

    In vitro environments like heat stress usually increase the production of reactive oxygen species in bubaline oocytes which have been implicated as one of the major causes for reduced developmental competence. Oocytes during meiotic maturation are sensitive to oxidative stress, and heat stress accelerates cellular metabolism, resulting in the higher production of free radicals. Therefore, the aim of present work was to assess the impact of heat stress during meiotic maturation on bubaline cumulus-oocyte complexes (COC), denuded oocytes (DO), and cumulus cell mass in terms of their oxidative status. Accordingly, for control group, COC were matured at 38.5 °C for complete 24 h of meiotic maturation and heat stress of 40.5 and 41.5 °C was applied to COC during the first 12 h of maturation and then moved to 38.5 °C for rest of the 12 h. In another group, COC after maturation were denuded from the surrounding cumulus cells by manual pipetting. Results indicated that the production of reactive oxygen species (ROS), lipid peroxides, and nitric oxide (NO) was significantly ( P stress (40.5 and 41.5 °C) during meiotic maturation compared to the oocytes matured under standard in vitro culture conditions (38.5 °C). Also, the antioxidant enzymatic activities of superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase were significantly ( P stress ensues oxidative stress in bubaline oocytes which triggers the induction of antioxidant enzymatic defense system for scavenging the ROS.

    Full Text Available In recent years, several studies have been carried out to evaluate and investigate the important diseases of swamp buffaloes (Bubalus carabanensis in Kalimantan . More attention has been focused on the case of acute infectious diseases and sudden death in the buffaloes . Fasciolosis black disease, acute enteritis, especially fatal enterotoxaemia haemorrhagic septicaemia . and trypanosomiasis (Surra, are some of the important diseases found in these animals . Black disease caused by toxigenic Clostridium novyi occurs in the presence of the organism in the liver and the degree of liver fluke Fasciola gigantica infestation . In regions where black disease is enzootic, Cl. novvi can be isolated from livers of normal healthy animals . In Hulu Sungai Utara district, South Kalimantan, the prevalence of fasciolosis caused by Fasciola gigantica in swamp buffalo was 77% in 1991 . A gross sudden change in diet due to seasonal changes could induce rumen and intestinal stasis, which provide a favourable environment for the rapid proliferation of commensal toxigenic Clostridium perfringens in the small intestine . Subsequent absorption of the toxin produced through the gut wall and its generalized dissemination culminated in a fatal enterotoxaemia . Haemorrhagic septicaemia (HS is an acute, fatal disease affecting swamp buffalo, and caused by Pasteurella multocida B : 2 . The swamp buffalo is particularly susceptible for HS, and the reported greatest losses of swamp buffalo in Kalimantan due to HS is recorded in 1980s. The clinical signs of Surra in swamp buffalo were also found in certain areas in Danau Panggang area . Hulu Sungai Utara district . Vaccination is the accepted method for controlling Black disease, enterotoxaemia and HS. Multi component vaccine, alum adjuvant containing at least 5 types of clostridial toxoids and P. multocida B2 bacterin have been used and provide good protection to the animals .

    In contrast with the past, the water buffalo is now not only a draft animal, but also an important food source of milk and meat. It is increasingly apparent that the water buffalo have huge potential for meat production, but its breeding needs to be investigated. Regarding the molecular mechanisms involved in the meat quality difference between the buffalo (Bubalus bulabis) and yellow cattle (Bos taurus), 12 chemical-physical characteristics related to the meat quality of longissimus thoracis muscles (LTM) have been compared at the age of 36 months. Intramuscular lipid and b* (yellowness) were greater in cattle than the buffalo, whereas a* (redness) was greater in the buffalo. Gene expression profiles were constructed by bovine genome array. A total of 8884 and 10,960 probes were detected in buffalo and cattle, respectively, with 1580 genes being differentially expressed. Over 400 probes were upregulated and nearly 1200 were downregulated in LTM of the buffalo, most being involved in ribosomal RNA (rRNA) processing, cholesterol homeostasis, regulation of transcription, response to hypoxia, and glycolysis. Quantitative real-time PCR was used to validate the microarray data. Enriched GO analyses of highly expressed genes in LTM showed that protein biosynthesis, striated muscle contraction, iron homeostasis, iron transport, glycolysis and glucose metabolism were similar between the buffalo and cattle. High protein content, low fat content and deep meat color of buffalo LTM may be closely associated with the increased expression of genes involved in cholesterol and iron homeostasis, while also reducing the expression of genes involved in ubiquitin-mediated proteolysis and protein oxidative phosphorylation. These results establish the groundwork for further studies on buffalo meat quality and will be beneficial in improving water buffalo breeding by molecular biotechnology.

    Full Text Available The Chinese swamp buffalo (Bubalis bubalis is vital to the lives of small farmers and has tremendous economic importance. However, a lack of genomic information has hampered research on augmenting marker assisted breeding programs in this species. Thus, a high-throughput transcriptomic sequencing of B. bubalis was conducted to generate transcriptomic sequence dataset for gene discovery and molecular marker development. Illumina paired-end sequencing generated a total of 54,109,173 raw reads. After trimming, de novo assembly was performed, which yielded 86,017 unigenes, with an average length of 972.41 bp, an N50 of 1,505 bp, and an average GC content of 49.92%. A total of 62,337 unigenes were successfully annotated. Among the annotated unigenes, 27,025 (43.35% and 23,232 (37.27% unigenes showed significant similarity to known proteins in NCBI non-redundant protein and Swiss-Prot databases (E-value < 1.0E-5, respectively. Of these annotated unigenes, 14,439 and 15,813 unigenes were assigned to the Gene Ontology (GO categories and EuKaryotic Ortholog Group (KOG cluster, respectively. In addition, a total of 14,167 unigenes were assigned to 331 Kyoto Encyclopedia of Genes and Genomes (KEGG pathways. Furthermore, 17,401 simple sequence repeats (SSRs were identified as potential molecular markers. One hundred and fifteen primer pairs were randomly selected for amplification to detect polymorphisms. The results revealed that 110 primer pairs (95.65% yielded PCR amplicons and 69 primer pairs (60.00% presented polymorphisms in 35 individual buffaloes. A phylogenetic analysis showed that the five swamp buffalo populations were clustered together, whereas two river buffalo breeds clustered separately. In the present study, the Illumina RNA-seq technology was utilized to perform transcriptome analysis and SSR marker discovery in the swamp buffalo without using a reference genome. Our findings will enrich the current SSR markers resources and help spearhead

    The aim of this study was to investigate the effects of mastitis on CL development and function and pregnancy rate in buffaloes. Sixty-six buffaloes (Bubalus bubalus) reared in a commercial farm at El-Beheira governorate, north of Egypt were used in this study. According to the visual observation of milk, physical examination of the udder and actual somatic cell count in milk, buffalo cows were divided into three groups: without mastitis (W), n = 23; subclinical mastitis (SC), n = 18; and clinical mastitis (C), n = 25. All buffalo cows were synchronized by double dose of PGF2α (11-day interval) and inseminated by frozen-thawed semen of fertile bull. Mean CL diameter was ultrasonically examined on Days 5, 9, 12, 16, 21, and 25 after artificial insemination (AI). Blood samples were taken on the days of ultrasonography for progesterone (P4) assay. Results indicated that pregnancy rates were lower (P Pregnancy rates reduced to 60.87%, 44.45%, and 16.00% in W, SC, and C, respectively, at Day 45 after insemination. Thus, the embryonic loss was 8.7%, 11.11%, and 12.00 % in W, SC, and C cows, respectively. Pregnancy rates decreased between 44.32% and 50.51% when mastitis occurred during Day -15 before to Day +30 after AI, compared with 59.22% in the uninfected cows. The diameter of CL was greater (P pregnancy rate. Accordingly, incidence of mastitis revealed suppression to both CL diameter and function leading to significant reduction in pregnancy outcome of buffalo cows.

  18. Genome Sequences of 11 Brucella abortus Isolates from Persistently Infected Italian Regions

    OpenAIRE

    2015-01-01

    Bovine brucellosis, typically caused by Brucella abortus, has been eradicated from much of the developed world. However, the disease remains prevalent in southern Italy, persisting as a public and livestock health concern. We report here the whole-genome sequences of 11 isolates from cattle (Bos taurus) and water buffalo (Bubalus bubalis) that are representative of the current genetic diversity of B. abortus lineages circulating in Italy.

    Full Text Available The low productivity of buffalo herds and condemnation of carcasses in slaughterhouses due to tuberculosis lesions have resulted in increasing economic losses because these animals cannot be treated and must be destroyed by sanitary slaughter. Tuberculosis is a widely distributed zoonosis that affects the beef supply chain of the Brazilian agribusiness economically and socially. Like cattle, buffaloes are sensitive to Mycobacterium bovis, which is the main causative agent of zoonotic tuberculosis. Tuberculosis in buffaloes has been reported in several countries, including Brazil. In order to control and eradicate this disease among cattle and buffaloes in Brazil, the Ministry of Agriculture, Livestock, and Supply created the National Program for the Control and Eradication of Brucellosis and Tuberculosis with the main objective of finding a significant number of disease-free herds throughout the national territory using reliable methods. This review summarizes the main data on the history of occurrence of M. bovis in Brazilian herds and the diagnostic methods for the disease in buffaloes. Little information is available on buffalo tuberculosis. Due to the increasing population of buffaloes and their economic importance, more studies investigating the occurrence and identification of tuberculosis in this species are clearly needed.

    Full Text Available Butter obtained from buffalo milk was compared with commercial products obtained from cow milk. One buffalo butter and two cow butters were subjected to sensory analysis using non-trained panelists. The acceptance related to sensorial characteristics (color, flavor, and firmness was evaluated through a 9 point structured hedonic scale varying from “I displeased extremely” to “I liked extremely”. Analysis of variance (ANOVA was performed to evaluate the sensory characteristics and the means were compared by Tukey’s Test at 5% of significance. The buffalo butter received lower scores than the others for all attributes. The greatest difference was observed for color, as the buffalo butter exhibited a white color contrasting with the yellow color of commercial butters, which is the pattern expected by the consumers. For flavor and firmness attributes, the buffalo butter received scores similar to the commercial products. These results show. These results shows that the buffalo’s butter has a good acceptance on local market, and this could be improved through the correction of product’s color, what can be obtained by adding a dye.

Three Murrah buffalos (Bubalus bubalis and three steers Holstein (Bos taurus, with an of 477 ± 47 kg and 518 ± 56 kg of average weight respectively, and with ruminal and duodenal cannulas were used; the animals were designed into two 3 ´ 3 latin squares and in a 3 ´ 2 factorial arrangement. The acid insoluble ash was the internal marker for fecal and duodenal flow. No interaction of diet and animal species for TDC of nutrients was observed, although the ionophore addition in the ration showed a positive effect on TDC for DM, CP, EE and starch and the probiotic addition increased TDC of starch, NDF and ADF. The ionophore and probiotic addition provided higher ruminal fermentation of NDF and ADF and higher IDC of starch. It was observed higher TDC of CP and starch for bovine and higher TDC of NDF for buffaloes. There was interaction of rations ´ species only on RDC and IDC for DM, CP and EE. The ionophore addition was effective to increase the ruminal fermentation of DM, to reduce ruminal degradation of CP and to increase IDC of CP for both species. The probiotic addition also reduces ruminal degradation of CP in buffaloes, but in lower scale than ionophore. For buffaloes, the presence or absence of additives in rations caused higher RDC of DM, the absence of addictives in ration caused higher RDC and lower IDC of CP than in bovine.

    Cesarean section in buffaloes is an emergency operative procedure being performed prinicipally for uncorrectable uterine torsions and for delivery of fetal monsters. Left paramedian (lateral and parallel to the milk vein) and oblique ventrolateral (above arcus cruralis) are the two common operative sites used for buffalo caesarean section. Although many anesthetic combinations including intravenous and inhalation anesthetic procedures have been experimented in the buffalo species yet most caesarean sections in buffaloes are satisfactorily performed in right lateral recumbency under mild sedation and local infiltration analgesia or paravertebral nerve blocks. The history, indications, anesthesia, operative procedures, post operative complications and future fertility following caesarean section in buffalo are described.

    Full Text Available The neuroendocrine functions of the pineal affect a wide variety of glandular and nervous system processes. Beside melatonin (MEL, the pineal gland secretes and expresses certain proteins essential for various physiological functions. It has been suggested that the pineal gland may also have an antioxidant role due to secretory product other than MEL. Therefore, the present study was designed to study the effect of buffalo (Bubalus bubalis pineal proteins (PP on the antioxidant defense system in the brain of female rats. The twenty-four rats were taken in present study and were divided into four groups: control (0 day, control (28 day, vehicle control and buffalo PP. The PP was injected 100 µg/kg BW intraperitoneal (i.p. daily for 28 days. The activities of superoxide dismutase (SOD, glutathione peroxidase (GPx, catalase (CAT, glutathione reductase (GR and reduced glutathione (GSH concentration and the levels of lipid peroxidation (LPO in the brain tissue were measured to assess the antioxidant systems. These enzymes protect from adverse effects of free radicals and help in amelioration of oxidative stress. Buffalo pineal proteins administration did not cause any effect on brain LPO, whereas GPx, GR and GSH were significantly (p < 0.05 decreased. However, SOD and CAT activities were increased to significant levels than the control in PP treated rats. Our study herein suggested that buffalo (Bubalus bubalis pineal proteins upregulates specific antioxidant defense systems and can be useful in control of various oxidative stress-induced neuronal diseases.

    Full Text Available Buffalo is a potential large ruminant that its contribution in national program on beef self sufficiency has been unrecognized in Indonesia. In rural community, buffalo has similar functions as cattle, it is used as draught animal, meat (beef producer, saving, milk producer, sacrificial ritual animal to social status. The peak of buffalo population was on 1925, 3.227 million heads in Java and 1.10 million in outside Java. The centers of cattle production sites for national program of self sufficiency on beef were formly as noted the centers of buffalo production. The introduction of Bali cattle to those former buffalo centers particularly in outside of Java depressed buffalo population and then dominated by Bali cattle. Then Bali cattle were noted to be the major beef animal supplier beside buffalo to the centers of consumers for domestic and export. This article aims to discuss the depleting buffalo population and to formulate development strategy. Historical approaches system and critical evaluation population, SWOT (strength, weaknesses, opportunity and threat analysis were used as tools for analyzing. Two case studies on herd survival from Banten indicated depleting population of buffalo. Despite low reproductive profile, strategic diseases and farmers’ institution needed to be optimized on services. Understanding criticizing on ecological habitats in the potential regions, the need of spatial planning for its development, zoning program for strategic diseases free, reproductive problems and village institution are the important areas of improvement for buffalo development in supporting beef self sufficiency and the welfare of rural people with their buffalo in sustainable beef production.

    Buffalo, as the major livestock species for milk and meat production, contribute significantly to the economy of many countries in south & south-east Asia, South America, Africa and the Mediterranean. Improved buffalo production could significantly enhance the economy and the living standards of farmers in countries where buffaloes predominate; particularly, in countries with a tropical climate. The major factors limiting the efficient utilization of buffaloes in countries with a tropical climate are: late maturity; poor estrus expressivities, particularly in summer months; long postpartum calving intervals; low reproductive efficiencies and fertility rates which are closely linked with environmental stress; as well as managerial problems. As good reproductive performance is essential for efficient livestock production, the female buffalo calves must grow rapidly to attain sexual maturity, initiate estrous cycles, ovulate and be mated by fertile males or inseminated with quality semen to optimize conception and production. In the last two decades, considerable attention has been focused on understanding some of the causes for the inherent limitations in reproduction among buffaloes by studying their reproductive endocrinology as well as developing biotechniques for augmenting their reproductive efficiency. This review provides an overview of buffalo reproductive endocrinology and also of the research done to date towards the enhancement of buffalo reproductive efficiency through endocrine and embryo biotechniques.

    To further probe into whether swamp buffaloes were domesticated once or multiple times in China, this survey examined the mitochondrial DNA (mtDNA) Control Region (D-loop) diversity of 471 individuals representing 22 populations of 455 Chinese swamp buffaloes and 16 river buffaloes. Phylogenetic analysis revealed that Chinese swamp buffaloes could be divided into two distinct lineages, A and B, which were defined previously. Of the two lineages, lineage A was predominant across all populations. For predominant lineage A, Southwestern buffalo populations possess the highest genetic diversity among the three hypothesized domestication centers (Southeastern, Central, and Southwestern China), suggesting Southwestern China as the most likely location for the domestication of lineage A. However, a complex pattern of diversity is detected for the lineage B, preventing the unambiguous pinpointing of the exact place of domestication center and suggesting the presence of a long-term, strong gene flow among swamp buffalo populations caused by extensive migrations of buffaloes and frequent human movements along the Yangtze River throughout history. Our current study suggests that Southwestern China is the most likely domestication center for lineage A, and may have been a primary center of swamp buffalo domestication. More archaeological and genetic evidence is needed to show the process of domestication.

    Objective: To evaluate the effects of lead in the morphology and viability of Fasciola gigantica(F. gigantica)(giant liver fluke) isolated from infected livers of carabaos in vitro using the following concentrations of lead: 0, 100, 150 and 200 mg/L. Methods: In vitro viability and motility assay was conducted to evaluate the ef ects of lead using 1% methylene blue as the vital dye for assessment of the l ukes’ viability. Results: Results indicate that F. gigantica can tolerate lead exposure as high as 200 mg/L with visible morphological variations. Upon exposure to lead, liver l ukes tend to curl and excrete black precipitates as a sign of physiological stress response. Furthermore, the lethal concentration(LC50) of lead against F. gigantica in vitro was 160 mg/L. Conclusions: In conclusion, tolerance of liver flukes to high levels of lead suggests its potential as a possible biomarker of environmental pollution.

    Full Text Available This is an introductory paper to the newly-designed African Buffalo Optimization (ABO algorithm for solving combinatorial and other optimization problems. The algorithm is inspired by the behavior of African buffalos, a species of wild cows known for their extensive migrant lifestyle. This paper presents an overview of major metaheuristic algorithms with the aim of providing a basis for the development of the African Buffalo Optimization algorithm which is a nature-inspired, population-based metaheuristic algorithm. Experimental results obtained from applying the novel ABO to solve a number of benchmark global optimization test functions as well as some symmetric and asymmetric Traveling Salesman’s Problems when compared to the results obtained from using other popular optimization methods show that the African Buffalo Optimization is a worthy addition to the growing number of swarm intelligence optimization techniques.

    Yasir Akhtar Khan

    Full Text Available Helminth parasites of veterinary importance cause huge revenue losses to agrarian economy worldwide. With the emergence of drug resistance against the current formulations, there is a need to focus on the alternative approaches in order to control this menace. In the present study, biocompatible zinc oxide nanoparticles (ZnO NPs were used to see their in vitro effect on the biliary amphistomes, Gigantocotyle explanatum, infecting Bubalus bubalis because these nanoparticles are involved in generation of free radicals that induce oxidative stress, resulting in disruption of cellular machinery. The ZnO NPs were synthesized by using egg albumin as a biotemplate and subsequently characterized by Scanning Electron Microscopy (SEM, Transmission Electron Microscopy (TEM, X-ray Diffraction and Spectrophotometrical, which showed that ZnO NPs were highly purified wurtzite type polycrystals, with a mean size of 16.7 nm. When the parasites were treated with lower concentrations (0.004% and 0.008% of the ZnO NPs, the worms mounted a protective response by stimulating the antioxidant system but the treatment of G. explanatum with 0.012% ZnO NPs produced significant inhibition of the antioxidant enzymes like superoxide dismutase (SOD (p< 0.05 and glutathione S- transferase (GST (p<0.01, while the level of malondialdehyde (MDA, a lipid peroxidation marker, was significantly (p< 0.01 elevated. SEM and histopathology revealed pronounced tegumental damage showing the disruption of surface papillae and the annulations, particularly in the posterior region near acetabulum. The under expression of a number of polypeptides, loss of worm motility in a time dependent manner, further reflect strong anthelmintic potential of ZnO NPs. It can be concluded that the anthelmintic effect might be due to the production of reactive oxygen species that target a variety of macromolecules such as nucleic acid, protein and lipids which are involved in different cellular processes.

    The water buffalo is vital to the lives of small farmers and to the economy of many countries worldwide. Not only are they draught animals, but they are also a source of meat, horns, skin and particularly the rich and precious milk that may be converted to creams, butter, yogurt and many cheeses. Genome analysis of water buffalo has advanced significantly in recent years. This review focuses on currently available genome resources in water buffalo in terms of cytogenetic characterization, whole genome mapping and next generation sequencing. No doubt, these resources indicate that genome science comes of age in the species and will provide knowledge and technologies to help optimize production potential, reproduction efficiency, product quality, nutritional value and resistance to diseases. As water buffalo and domestic cattle, both members of the Bovidae family, are closely related, the vast amount of cattle genetic/genomic resources might serve as shortcuts for the buffalo community to further advance genome science and biotechnologies in the species.

    Full Text Available The aim of this work was to evaluate the incidence of embryonic mortality in three different period of year in buffaloes naturally mated. The trial was carried out in a buffalo farm located in Caserta province between 2000-2006. In this period were registered natural insemination on 200 buffaloes. Pregnancy diagnosis was carried out on Day 30, confirmed on Day 45 and every 15th days until 90 days after natural mating. Buffaloes that were pregnant on Day 30 but not on Day 45 or Day 90 were considered to have undergone embryonic (EM or fetal mortality (FM respectively. EM and FM were 8.8% and 13.4% respectively throughout the experimental period. A high incidence (P<0.01 of FM was found in the transitional period (December-March than in other months of the year. The incidence of embryonic mortality was significantly (P<0.01 higher between 28-60 days of gestation and lower after 71 day of gestation. The higher fetal mortality found in this study could be due the lower serum levels of progesterone normally found in transitional period in buffalo cows.

    This review covers a historical view and etiology of oedematous skin disease which affects buffalo in Egypt, the microbiology of Corynebacterium pseudotuberculosis causing the disease: its virulence; clinical signs; mechanism of pathogenesis; histopathology; mode of transmission; immunological aspects; treatment and control. It is concluded that C. pseudotuberculosis serotype II is the main cause of OSD and exotoxin phospholipase D and its lipid contents of the cell wall are the major causes of pathogenesis. After declaring the role of Hippobosca equina in transmission of the causative agent among buffaloes, control of OSD is now available.

    Full Text Available Problem statement: The use of water buffalo labor for farming and the tie between rice farmers and water buffaloes at present are greatly decreasing because rice farmers give more importance to modern ploughing machines than water buffaloes. Therefore, water buffalo raising and traditions and rituals involving them which have been useful to humans for a very long time almost all disappear from Isan (Northeast Thailand. The purposes were to examine current conditions and problems and indigenous knowledge of the use of water buffaloes and to investigate the process of conservation and development of the use of water buffaloes in different forms in Isan. The study was conducted in Isan covering 8 Changwats: Nakhon Phanom, Sakon Nakhon Nong Bua Lam Phu, Udon Thani, Khon Kaen, Ubon Ratchathani, Kalasin and Roi Et. Approach: The qualitative research methodology was used. Data were collected from related literature and field studies using structured and unstructured-interview forms, workshop and focus group discussion with 199 informants. The findings were presented by means of a descriptive analysis. Results: The findings revealed the following. The conservation and development of indigenous knowledge of the use of water buffaloes in all the 8 Changwats of Isan had increasingly changed from the past. For water buffalo conservation at present, they have formed groups in cooperation with government agencies involved according to the government policy in each period. The group members are not confident that their own group will be able to sustainably exist due to the factors which are the state policy in other parts involved. Some factors can impact the water buffalo conservation groups such as limited places for water buffalo raising, the buffalo raising places being changed to be pare tree farms, for planting eucalyptus trees and others. In developing indigenous knowledge, the uses of water buffaloes as labor and in different cultural rituals and

  10. Repeat breeding: Incidence, risk factors and diagnosis in buffaloes

    2016-04-01

    Full Text Available Repeat breeding in buffaloes was evaluated in terms of incidence, risk factors and diagnosis. The incidence of repeat breeding is low in buffaloes however in different studies the incidence varied from 0.70% to 30%. Because of seasonal suppression of fertility repeat breeding in buffaloes should be limited to the breeding season. Spring and winter calving, first parity, peri-parturient disease and lactation are significant risk factors for repeat breeding in buffaloes. The etiologies of repeat breeding in buffaloes can be failure of fertilization and early embryonic deaths. Only a few of causes of failure of fertilization have been identified in buffaloes. Ovulatory disturbances and ovarian cysts are uncommon in buffaloes and cysts have poor clinical manifestation. Endometritis is the common female cause of fertilization failures in buffaloes whereas poor semen quality and improper insemination are the bull side factors for fertilization failures. Early embryonic deaths are common in buffaloes mated/inseminated during the end of the breeding season due to a low luteal progesterone however embryonic deaths occur late (<25 days in buffaloes. Diagnostic approaches for repeat breeding include vaginoscopic and transrectal examination and uterine cytology for genital health. More precise evaluations of the ovarian and uterine function can be obtained by ultrasonographic and hysteroscopic examinations performed sequentially however, precise diagnosis of the cause of repeat breeding seems difficult.

  11. Unexpected high genetic diversity at the extreme northern geographic limit of Taurulus bubalis (Euphrasen, 1786.

    Directory of Open Access Journals (Sweden)

    Vítor C Almada

    Full Text Available The longspined bullhead (Taurulus bubalis, Euphrasen 1786 belongs to the family Cottidae and is a rocky shore species that inhabits the intertidal zones of the Eastern Atlantic since Iceland, southward to Portugal and also the North Sea and Baltic, northward to the Gulf of Finland, with some occurrences in the northern Mediterranean coasts eastward to the Gulf of Genoa. We analysed the phylogeographic patterns of this species using mitochondrial and nuclear markers in populations throughout most of its distributional range in west Europe. We found that T. bubalis has a relatively shallow genealogy with some differentiation between Atlantic and North Sea. Genetic diversity was homogeneous across all populations studied. The possibility of a glacial refugium near the North Sea is discussed. In many, but not all, marine temperate organisms, patterns of diversity are similar across the species range. If this phenomenon proves to be most common in cold adapted species, it may reflect the availability of glacial refugia not far from their present-day northern limits.

    Full Text Available Leptin is a protein involved in the regulation of feed intake, fat metabolism, whole body energy balance, reproduction and hematopoiesis. In cattle Leptin gene has been considered a potential QTL influencing several production traits like meat production, milk performance and reproduction. Several studies on bovine leptin gene have found association between polymorphisms and traits like milk yield, feed intake, fat content, carcass and meat quality. With the aim to assess the presence of sequences polymorphisms in the Buffalo leptin gene, we sequenced the entire coding region and part of the introns on a panel of Italian River Buffalos. In this study we identified a new set of SNP (Single Nucleotide Polymorphism useful for association studies.

    In the present work, controlled experimental infection and transmission studies in domestic cattle (Bos taurus) and water buffaloes (Bubalus bubalis) were carried out to study the in vivo behaviour of bubaline herpesvirus 1 (BuHV1). Two bovine and two buffalo calves were infected with BuHV1 (20287N isolate) by intranasal aerosolisation. Two sentinel cattle did not receive the virus challenge, but were housed with infected buffaloes to evaluate horizontal transmission. All experimentally inoculated animals showed viral infection and respiratory clinical signs. BuHV1 experimentally infected calves showed intermittent viral excretion between 2 days and 18 days postinfection (dpi) with a maximum titre of excretion of 106 TCID50/ml and moderate rhinitis between 2 dpi and 20 dpi. BuHV1 experimentally inoculated buffaloes showed mild respiratory signs, which consisted mainly of serous nasal secretions during the infection period. Sentinel calves showed mucosal specific IgG1 antibodies at seven days postcontact. Viral DNA was detected by PCR and sequencing in both buffaloes and sentinel calves, which could be associated with latency. In conclusion, this study showed the susceptibility of cattle to BuHV1 after both experimental infection and contact with infected buffaloes. These data increase the scarce knowledge on the pathogenesis in natural host and the susceptibility of cattle to BuHV1 experimental infection. PMID:28074144

    2012-04-01

    Full Text Available We review the causes of fetal dystocia in cows and buffalo. Two fetal causes are distinct fetal oversize and fetal abnormalities. Fetal oversize is common in heifers, cows of beef cattle breeds, prolonged gestations, increased calf birth weight, male calves and perinatal fetal death with resultant emphysema. Fetal abnormalities include monsters, fetal diseases and fetal maldispositions, and it is difficult to deliver such fetuses because of their altered shape. Although monsters are rare in cattle, a large number of monstrosities have been reported in river buffalo; yet also here, overall incidence is low. Diseases of the fetus resulting in dystocia include hydrocephalus, ascites, anasarca and hydrothorax. The most common cause of dystocia in cattle seems to be fetal maldispositions, of which limb flexion and head deviation appear to be the most frequent. We provide a brief description of the management of dystocia from different causes in cattle and buffalo. A case analysis of 192 and 112 dystocia in cattle and buffalo, respectively, at our referral center revealed that dystocia is significantly higher (P<0.05 in first and second parity cows and buffalo, and that dystocia of fetal origin is common in cows (65.62% but less frequent (40.17% in buffalo. In buffalo, the single biggest cause of dystocia was uterine torsion (53.57%. Fetal survival was significantly (P<0.05 higher both in cows and buffalo when delivery was completed within 12 h of second stage of labor.

    In order to contribute to the breeding programmes of Asian water buffalo, the aim of this study was to analyse the influence of genetic effects in the stayability of Murrah dairy buffaloes. The stayability trait (ST) was defined as the female's ability to stay in the herd for one (ST1), two (ST2), three (ST3), four (ST4), five (ST5) or six years (ST6) after the first calving. The same trait was also considered as continuous and was designated stayability in days up to one (STD1), two (STD2), three (STD3), four (STD4), five (STD5) or six years (STD6) after the first calving. Data from 1016 females reared in nine herds located in the State of São Paulo, Brazil, were analysed. Statistical models included the additive genetic effect of the animal and the fixed effects of the buffalo breeding herd, birth year and birth season. Additive effects for ST were estimated by approximate restricted maximum likelihood using a threshold model, while for STD, the additive effects were estimated by restricted maximum likelihood. Heritability estimates were lower for ST, except for ST1, (0.11+/-0.07, 0.17+/-0.06, 0.23+/-0.06, 0.16+/-0.08, 0.14+/-0.09 and 0.16+/-0.10 for ST1, ST2, ST3, ST4, ST5 and ST6, respectively) when compared with STD (0.05+/-0.06, 0.18+/-0.08, 0.40+/-0.10, 0.49+/-0.11, 0.41+/-0.11 and 0.30+/-0.13, for STD1, STD2, STD3, STD4, STD5 and STD6, respectively). Considering the values of heritability and owing to the serial nature of STD to a specific age, selection for STD3 should have a favourable influence on STD to other ages.

    Concentrations of fenbendazole and of drug metabolites in plasma were measured in buffalo and cross-bred cattle after single intraruminal administration at two different doses. Plasma concentrations of the parent compound fenbendazole and the two metabolites, viz. oxfendazole and fenbendazole sulfone, were much lower in buffalo compared with cattle, at a dose of 7.5 mg/kg body weight as indicated by lower area under concentration curve and concentration maximum. At a dose of 15 mg/kg body weight there were corresponding increases in plasma metabolite concentrations in cattle. However, buffaloes did not show a similar corresponding increase.

  6. Molecular characterization of water buffalo meat by proteomic techniques

    2010-02-01

    Full Text Available Buffalo breeding in Campania is aimed at milk production as the starting material for the production of Mozzarella di Bufala DOP, but it does not take into account the possibility of meat production. Buffalo meat, given its low content in fat and cholesterol, represents a good alternative to bovine meat from the dietetic standpoint. One of most interesting aspects of buffalo meat is its utilization either directly or to prepare other products. Development of these products however requires suitable technological approaches based on molecular characterization, so that product evaluation and development may be carried out on rational basis.

    Action of proteinases viz. trypsin and chymotrypsin, and neuraminidase on intact erythrocyte membrane proteins and glycophorins (sialoglycoproteins) exposed to cell surface and its impact on lectin (concanavalin A)-mediated agglutination were studied in Homo sapiens (human), Capra aegagrus hircus (goat) and Bubalus bubalis (buffalo). Membrane proteins and glycophorins analysis by SDS-PAGE as visualized by coomassie brilliant blue and periodic acid-schiff stains, respectively, and agglutination behaviour revealed marked differences: 1) there were prominent dissimilarities in the number and molecular weights of glycophorins in human, goat and buffalo erythrocyte membranes; 2) proteinase action(s) on human and buffalo erythrocyte surface membrane proteins and glycophorins showed similarity but was found different in goat; 3) significant differences in erythrocyte agglutinability with concanavalin A can be attributed to differences in membrane composition and alterations in the surface proteins after enzyme treatment; 4) a direct correlation was found between degradation of glycophorins and concanavalin A agglutinability; 5) action of neuraminidase specifically indicated the negative role of cell surface sialic acids in determining concanavalin A agglutinability of goat and buffalo erythrocytes, similar to human. Present studies clearly indicate that there are some basic differences in human, goat and buffalo erythrocyte membrane proteins, especially with respect to glycophorins, which determine the concanavalin A-mediated agglutination in enzyme treated erythrocytes.

    2015-10-01

    The degradation kinetics of swine and buffalo manure for methane production was investigated. Six kinetic models were employed to describe the corresponding experimental data. These models were evaluated by two statistical measurements, which were root mean square prediction error (RMSPE) and Akaike's information criterion (AIC). The results showed that the logistic and Fitzhugh models could predict the experimental data very well for the digestion of swine and buffalo manure, respectively. The predicted methane yield potential for swine and buffalo manure was 487.9 and 340.4 mL CH4/g volatile solid (VS), respectively, which was close to experimental values, when the digestion temperature was 36 ± 1 °C in the biochemical methane potential assays. Besides, the rate constant revealed that swine manure had a much faster methane production rate than buffalo manure.

    Zhang, Jiapu

    2015-01-01

    It was reported that buffalo is a low susceptibility species resisting to TSEs (Transmissible Spongiform Encephalopathies) (same as rabbits, horses and dogs). TSEs, also called prion diseases, are invariably fatal and highly infectious neurodegenerative diseases that affect a wide variety of species (in humans prion diseases are (v)CJDs, GSS, FFI, and kulu etc). It was reported that buffalo is a low susceptibility species resisting to prion diseases (as rabbits, dogs, horses). In molecular structures, these neurodegenerative diseases are caused by the conversion from a soluble normal cellular prion protein, predominantly with alpha-helices, into insoluble abnormally folded infectious prions, rich in beta-sheets. This paper studies the molecular structure and structural dynamics of buffalo prion protein, in order to find out the reason why buffaloes are resistant to prion diseases. We first did molecular modeling a homology structure constructed by one mutation at residue 143 from the Nuclear Magnetic Resonanc...

Experiments were conducted to note three end points: (1) nuclear maturation 24 h after culture (eight replicates); (2) fertilization 24 h after insemination (10 replicates); (3) development to blastocysts (nine replicates). The oocytes were cultured in groups of up to five per drop. Using a two-way (5 x 2) factorial model with interactions, the results were compared using generalized linear models with binomial errors and the logit link function. In experiment 1, the proportion of oocytes reaching metaphase II was higher for all the supplement treatments than the control treatment (t = 3.68, p hormone (chi2 = 17.23, p hormones (31.0%, chi2 = 12.5, p = 0.0004), IGF-1 (35.7%, chi2 = 20.53, p produce a significantly higher rate of progression to blastocysts compared to the control. Once again, media had no effect on outcome. It was concluded that maturation, fertilization and development of buffalo oocytes were enhanced by all supplements tested. Enhancement was maximal with the combination of EGF+IGF-1. In contrast, no significant differences were found between the two types of media used.

    Full Text Available Sulfamethazine is a sulfonamide that presents a broad spectrum of activity, including Gram-positive and Gram-negative bacteria, Chlamydia spp. and some protozoa and it commonly used in ruminants. The aim of our work was to study the possible inter-species differences in the pharmacokinetic behavior and pharmacokinetic/ pharmacodynamic(PK/PD integration of sulfamethazine after intravenous administration in buffalo and bovine. A single intravenous dose of 60 mg/kg was administered to six bovine and five buffalo (3-4 month old and weighting 120±15kg. Plasma concentrations of sulfamethazine were determined by high performance liquid chromatography. Differences between bovine and buffalo calves were found in t½λ (buffaloes: t1/2λ =6.17±0.58h; bovine t1/2λ=7.46±1.05h, Cl (buffaloes: 45.31ml/h·kg; bovines 30.34ml/h·kg. As a consequence of the lower clearance in bovines, the AUC and t½λ values were higher in this species. Important differences between bovine and buffalo exist for microorganisms that have a MIC value<32μg/ml related to time over minimum inhibitory concentration and weighted AUC.

    Full Text Available The trial was conducted to assess anoestrous problem in Nili Ravi buffaloes kept under rural and peri-urban management around Islamabad, during the months of October to December. One hundred and three buffaloes under peri-urban management and 40 buffaloes under rural management belonging to six and 21 farmers, respectively, were included in this study. Buffaloes that did not show heat signs for 6-12 months postpartum were considered anoestrus in this study. For inducing heat, two injections of cloprostenol were administered in silent oestrous buffaloes, whereas gonadotropin releasing hormone followed by cloprostenol was administered in true anoestrous buffaloes. A higher proportion of buffaloes (35% was noted in anoestrus under rural than under peri-urban management (17.5%, P=0.02. All the buffaloes diagnosed as silent oestrus responded to cloprostenol therapy by showing heat signs under both management systems. However 71% rural buffaloes diagnosed in true anoestrus showed heat symptoms compared to 100% peri-urban buffaloes followed by GnRH+cloprostenol therapy. Fixed time insemination (72 and 96 hours after 2nd cloprostenol injection resulted in a conception rate of 58% and 67% in rural and peri-urban buffaloes, respectively. An overall 33% conception rate was observed in true anoestrous compared to 83% in silent oestrous buffaloes. It is concluded that cloprostenol could be used successfully to induce heat and achieve an optimum conception rate in silent oestrous buffaloes during peak breeding season.

  19. Altertative trophy measuring techniques for African buffalo

    Full Text Available The African buffalo is considered the classic African trophy. It is the choice of many hunters who will never go on to hunt any of the other dangerous game animals on the continent. A good trophy is perceived as that of a mature bull with a hardened boss and horn tips that lengthen into sharply pointed hooks. However, indications are that these are the bulls in their breeding prime and there is concern that the continued targeting of these individuals will negatively impact on the population dynamics of the herds, ultimately affecting the sustainability of buffalo hunting. As they age and become postreproductive, the horns broom down, reducing the trophy score under the current measurement systems. A new measuring system is needed that encourages hunters to target the older post-reproductive bulls, instead of those that are still breeding. A random sample of trophies was divided into broomed and non-broomed sub-samples. All key parameters that can be measured in the trophy were measured with a view to identifying the parameters that would allow broomed-down individuals to compete favourably with the non-broomed “classic trophy” in the primary measurement systems, those of Safari Club International and Rowland Ward. An index, created through dividing tip space by the mean of the two individual horn lengths proved to serve the purpose. This factor was then applied to the mean of the SCI and Rowland Ward measurements in the samples. These methods allowed broomed horns to score more points in the record books than non-broomed horns. Boss width and boss space are other possible measurement inclusions that could be considered.

    Sex preselection by flow sorting of X- and Y-sperm has been proven to be an efficient and economically feasible strategy for use in Holstein dairy cow breeding, and previous reports have demonstrated the feasibility of altering the sex ratio in buffalo species by using sexed semen in either artificial insemination or IVF. However, because buffalo reproductive physiology and farm management are different from Holsteins, factors involved in artificial insemination by sexed semen need to be further addressed before being applied in buffalo breeding at village-level husbandry. In this study, a total of 4521 swamp or crossbred (F1 or F2) buffaloes with natural estrus were inseminated with X-sorted sperm from river buffaloes, resulting in a 48.5% (2194 of 4521) pregnancy rate and 87.6% (1895 of 2163) sex accuracy in the derived calves. The pregnancy rate obtained with sexed semen from Murrah bulls was higher than that of Nili-Ravi, 52.5% (895 of 1706) versus 46.1% (1299 of 2815; P inseminations performed in different seasons (P insemination with sexed semen. The findings in the present study under field conditions pave the way for application of sexing technology to buffalo breeding under village-level husbandry and diverse genetic backgrounds.

    Full Text Available Aim: To study epidemiology of forestomach (reticuloruminal, omasal, and abomasal disorders in cattle and buffaloes. Materials and Methods: The 106 buffaloes and 32 cattle referred for treatment to the university large animals teaching hospital with the complaint of gastrointestinal diseases constituted the study material. The cases were diagnosed based on history, clinical examination, hematology, biochemistry, radiography, peritoneal fluid analysis and ultrasonography, rumenotomy, and postmortem. A questionnaire was prepared containing important information on housing, husbandry practices, including feeding practices and individual animal information viz. age, species, month of the year, parity, gestation (month, and recent parturition. The animals were divided into eight groups and analysis of variance was performed to study risk factors associated with each condition. Results: The forestomach disorders are widely prevalent in cattle and buffaloes between April and October, during summer and rainy season (90% and constituted a significant proportion of diseased cows and buffaloes (138/1840 at the hospital. Different forestomach disorders and their prevalence was: Diaphragmatic hernia (DH 17%, traumatic reticuloperitonitis (TRP 14%, idiopathic motility disorder or vagus indigestion (VI 22%, adhesive peritonitis (AP 13%, frank exudative peritonitis (FEP 12%, reticular abscess (RA 8%, ruminal and omasal impaction (RI 5%, and abomaso duodenal ulceration (ADU 9%. DH and RA were significantly more common in buffaloes as compared to cattle. Similarly, impactions were more in buffaloes but its incidence was very low (5%. ADU was present in buffalo as commonly as in cows. Exclusive feeding of wheat straw was present in an abysmally low number of animals and hence could not be considered the cause of these disorders. DH was significantly higher in buffaloes (>5 years of 5-8 years of age and TRP, VI and AP were observed in cattle and buffalo of 2-8 years

    Full Text Available Global warming is likely to impact productivity of buffaloes due to their sensitivity to temperature changes. Air temperature, humidity, wind velocity and solar radiation are the main climate variables that affect buffalo production in tropical climate. In the present study sensitivity of lactating Murrah buffaloes to sudden temperature (Tmax, Tmin change and THI have been analyzed from milk production and climatic records (1994-2004 of Karnal. Algorithms were developed and validated on lactating buffaloes during 2005-2006 at the Institute. A sudden change (rise or fall in Maximum/Minimum temperature during summer and winter was observed to affect milk production. The decline in minimum temperature (>3°C during winter and increase (>4°C during summer than normal were observed to negatively impact milk production upto 30% on the next or subsequent days after extreme event. The return to normal milk production depended on severity and time period of thermal stress/ event occurrence. The R² was very low for cool period observed during Feb- April/Sept-Nov and actual effect on milk production was minimum. This indicated that low THI had a relatively small effect on milk production performance. The lactation period of animals are shortened during extreme summer when THI were more than 80 and reproductive functions were also adversely affected. Thermal stressed buffaloes did not exhibit estrus or exhibited estrus for short period. The potential direct effects of possible climate change and global warming on summer season milk production of Murrah buffaloes were evaluated using widely known global circulation model UKMO to represent possible scenarios of future climate. Both milk production and reproductive functions of Murrah buffaloes are likely to be affected due to warming effects.

    Full Text Available An investigation was carried out during the month of May to August 2001 to diagnose hind limbs paralysis in buffaloes of Buner area of NWFP. Serum concentrations of calcium (Ca and phosphorus (P in 40 buffaloes (29 affected and 11 normal from six different villages were measured together with feed and soil samples analysed for different macro and micro minerals. Serum P level was lower (P<0.001 in affected buffaloes and averaged 3.05 mg/100 ml of serum against 6.73 mg/100 ml found in the normal buffaloes. Serum Ca level was in normal range and did not differ between affected and normal buffaloes (12.16 and 12.93 mg/100 ml, respectively. Range grass hay, the main feed offered to the animals during dry season of high disease incidence, was extremely low in P (0.10mg/100g and sodium (0.03g/100g, with adequate level of Ca (0.41 g/100 g. Concentrations of potassium (K and magnesium (Mg in range grass hay were very high and averaged 5.0 and 0.34g/100 g, respectively. Copper (Cu, manganese (Mn and iron (Fe contents in the hay were 28.50, 113.0 and 242.0 g/g, respectively and were in excess of the recommended dietary requirements for cattle. However, zinc (Zn concentration (42.33 g/g in the hay was marginally adequate to meet the dietary requirement of dairy cattle. The mineral profile of hay was in close agreement with that of soil in the area. The results concluded that deficiency of P in hay, which might have resulted due to low P in soil, described low serum P in buffaloes and might be the major cause of the disease. The imbalance of other minerals in hay and soil might have also reduced the bioavailability of P to plants and animals. In vitro matter digestibility (38.1%, crude protein (5.63% in DM, and metabolizable energy (1.32 Mcal/kg DM values of the hay offered to animals were below the standard requirements and caused general emaciation of the buffaloes during dry seasons.

    Full Text Available Pakistan being an agricultural country supports a national herd of 28.4 million buffaloe which constitutes 8-10% of the global buffaloe population. Buffaloe contributes 72% of the national milk supply. Buffaloe is intricately interwoven with the social fabric of the rural families. In these areas it is mainly raised for milk production. Pakistan is the largest buffaloe meat producer followed by India, China, Thailand and Vietnam. The share of buffaloe’s meat at national level is over 55%. Slaughtering of male young calves for meat is common which has high degree of preference among the consumers. Fattening is rarely practiced, as there is poor price structure for beef. Female calves are usually raised for future herds. Little effort has been done so far to feed them on scientific lines. Mortality is high in calves during pre-weaning age. Seasonal variation in mortality is common. Poor nutrition, health and management have been demonstrated to be the main contributory factors affecting the calves’ survival.

    This paper proposes the African Buffalo Optimization (ABO) which is a new metaheuristic algorithm that is derived from careful observation of the African buffalos, a species of wild cows, in the African forests and savannahs. This animal displays uncommon intelligence, strategic organizational skills, and exceptional navigational ingenuity in its traversal of the African landscape in search for food. The African Buffalo Optimization builds a mathematical model from the behavior of this animal and uses the model to solve 33 benchmark symmetric Traveling Salesman's Problem and six difficult asymmetric instances from the TSPLIB. This study shows that buffalos are able to ensure excellent exploration and exploitation of the search space through regular communication, cooperation, and good memory of its previous personal exploits as well as tapping from the herd's collective exploits. The results obtained by using the ABO to solve these TSP cases were benchmarked against the results obtained by using other popular algorithms. The results obtained using the African Buffalo Optimization algorithm are very competitive. PMID:26880872

    Full Text Available Parasitism is the major problem affecting livestock in many parts of the world. Amongst these parasitic problems, the warble fly infestation (hypodermosis is a notorious and common malady of cattle, buffalo, sheep and goat in Pakistan. The disease is endemic in cattle, buffalo, sheep and goats in semi-hilly and mountainous areas of Pakistan. Keeping in view the importance of buffaloes an epidemiological survey was conducted to find the prevalence of hypodermosis in district Chakwal, Punjab, Pakistan, during the year 2005- 2006. Buffaloes are mainly kept for milk purpose in the study area. Out of 2000 buffaloes examined clinically, for grub infestation in the study area 125 (6.25% and 37 (5.20% found to be positive for the warble fly infestation in slaughter house as well as in the field. A prevalence variation among the male and female animals was also observed during the study. The factors of climatic conditions that favor the fly activity and contribute in the onset of disease.

    Full Text Available A study was carried out to determine the point prevalence of various helminths of cattle and buffalo population of district Toba Tek Singh, Pakistan and economic benefits of deworming with oxyclozanide. Out of 540 fecal samples examined, 205 (37.96% were found infected with helminths. Significantly higher (OR=2.2; P<0.05 prevalence of helminths was recorded in buffaloes (40%; 112/280 as compared to cattle (35.77%; 93/260. Oesophagostomum, Cooperia, Trichostrongylus, Strongyloide, Ostertagia, Fasciola (F. hepatica, F. gigantica and Haemonchus contortus were the helminth species identified in the study area. Oxyclozanide medicated buffaloes (E=96.66% and cattle (E=95.64% showed a significant decrease in fecal egg counts on day 14 post-treatment. An average daily increase of 0.89 and 0.71 liters of milk along with 0.42 and 0.37% more fat per buffalo and cattle, respectively was observed in oxyclozanide medication. The economic value of reduced production of infected animals was estimated as US$ 0.47 (Pak Rupees 40 and US$ 0.41 (Pak Rupees 35 per animal per day for cattle and buffaloes, respectively. It can be concluded that single dose of oxyclozanide is effective against all bovine helminths.

    An outbreak of foot-and-mouth disease (FMD) affecting cattle and water buffalo (Bubalus bubalis) occurred in Egypt during 2012/2013. The present study was undertaken to determine the current strains of the FMD virus (FMDV) and the prevalence of FMD among cattle and buffalo in Gharbia, Egypt. The diagnostic sensitivity of two RT-PCR assays for the detection of FMDV was evaluated. The results revealed that SAT2 was the causative agent. The percentage of infected of animals varied with the detection method, ranging from 62.5 % by the untranslated region (UTR) RT-PCR to 75.6 % by SAT2 RT-PCR. The overall prevalence and mortality rates were 100 and 21 %, respectively. The mortality was higher in buffalo (23.3 %) than it was in cattle (17 %). A partial sequence of SAT2 was identical (90-100 %) to Egyptian isolates and was close in similarity to sequences from Sudan and Libya. In conclusion, FMD in Egypt is caused by SAT2. No other serotypes were detected. The results of this study provided the valuable data regarding the epidemiology of SAT2 in cattle and water buffalo from Egypt, which strengthens the need to change the strategies of both control and prevention that help to prevent the spread of the disease.

    Full Text Available Twenty buffaloes and twenty Vietnamese yellow cattle from peri-urban Hue city were kept indoor and used for measurement of effect of environmental temperature (To and humidity (H%. The To and H% were recorded by thermo-hygrometers for temperature and humidity index (THI measurement. Breathing rate was observed by moving rate of diaphragm, heart beat rhythms was calculated by stethoscope around 3 to 4 ribs and body To tested by 42oC thermo-meters in animal rectums. The results showed that the To in the area studied varied widely during the day and when To increased H% often decreased. During the study period the average To changed from 24oC in February to 39oC in May. The H% varied from 57 to 86. The environmental To and H% had very little effect on body To for both types of animals (37oC to 39oC but there were changes in heart beat from 42 to 45 in cattle but from 44 to 57 in buffaloes. In warmest period with high H% (THI 83 breathing rates in cattle varied from 18 to 21 while in buffaloes from 20 to 35 and in May it increased to 50. At the warmest time of the day the heart beat in cattle were 42 while in buffaloes 57. The breathing rate in cattle only increased when ambient To was above 39 degrees. The results clearly showed that buffaloes were easily stressed when To and H% increased. Buffaloes need water and swamps to help to avoid heat stress while indigenous cattle are much better adapted to high environmental To and H%.

    Full Text Available For this study, 60 buffaloes suffering from parturient hemoglobinuria (PHU were randomly selected from field cases occurring in three districts of Punjab, Pakistan and simultaneously, 60 clinically healthy buffaloes of similar description from the same localities were included for case control study. Clinico-epidemiological data were collected. Blood/serum samples from all buffaloes were collected and analyzed. The most prominent clinical sign was passing of red to coffee colored urine. Milk production was reduced and respiration and pulse rates were significantly accelerated. Ruminal motility was significantly weak and reduced along with characteristic straining while defecating. The case fatality was 15%. A significantly high occurrence of PHU was observed in the winter season (41.8%. Maximum number of affected buffaloes (25.0% was in 4th lactation. Twenty-seven (45.0% buffaloes developed hemoglobinuria in the post calving period and majority (59.3% of these were within 1-23 days of calving. Of the 33 (55.0% PHU affected pregnant buffaloes, 18 (54.6% were in their third trimester. The highest cases of PHU were observed in buffaloes producing 10 or more liters of milk/day (42.5%. Recurrence of PHU was observed in 18.3% buffaloes. Mean values of total erythrocyte counts, hemoglobin concentration and packed cell volume were lower (P<0.001, while erythrocyte sediment rate was higher (P<0.001 in PHU affected buffaloes as compared to the values in healthy buffaloes. Neutrophils were significantly higher, while lymphocytes and erythrocytic glucose-6-phosphate dehydrogenase (G6PD were lower, in PHU affected buffaloes than in healthy buffaloes. Serum phosphorus, copper and selenium were significantly (P<0.001 lower, whereas potassium, iron and molybdenum (P<0.001 were higher in buffaloes suffering from PHU than healthy buffaloes.

    Full Text Available The study concerns images of vibrating spermatozoa in the ejaculation of buffalo bulls from Bulgarian murrah breed through the method of Tchakarov and Natchev [1962], obtained at 5 sec exposures, optimal for this particular species. The negative registration material has been developed with high-equalising developer by Windisch, which reduces the glow due to overexposure around highaktinic parts of spermatozoa. On the basis of the positive graphic material – kinesigrams, we have established and analysed the main movement patterns of vibrating spermatozoa: with vibrating tail; with vibrating head; with a vibrating tail and head; with whole bilateral vibration; vibrating in circle; chaotically vibrating. We have described the differences in photokinesigraphic images of spermatozoa within given subclass.

    Full Text Available Problem statement: The use of water buffalo labor for farming and tie between rice farmers and water buffaloes at present are greatly decreasing because rice farmers give more importance to modern ploughing machines than water buffaloes. Water buffalo rising and traditions and rituals involving them which have been useful to humans for a very long time almost all disappear from Isan (Northeast Thailand. The purposes were to examine current conditions and problems and indigenous knowledge of the use of water buffaloes and to investigate the process of conservation and development of the use of water buffaloes in different forms in Isan. The study was conducted in Isan covering 8 Changwats: Nakhon Phanom, Sakon Nakhon Nong Bua Lam Phu, Udon Thani, Khon Kaen, Ubon Ratchathani, Kalasin and Roi ET. Approach: The qualitative research methodology was used. Data was collected from related literature and field studies using structured and unstructured-interview forms, workshop and focus group discussion with 199 informants. The findings were presented by means of a descriptive analysis. Results: The conservation and development of indigenous knowledge of the use of water buffaloes in all the 8 Changwats of Isan had increasingly changed from the past. For water buffalo conservation at present, they have formed groups in cooperation with government agencies involved according to government policy in each period. The group members are not confident that their own group will be able to sustainably exist due to the factors which are the state policy in other parts involved. Some factors can impact the water buffalo conservation groups such as limited places for water buffalo rising, the buffalo rising places being changed to be pear tree farms, for planting eucalyptus trees and others. The uses of water buffaloes as labor and in different cultural rituals and traditions have decreased because the number of water buffalo risers is small

    Full Text Available In order to verify the effect of a pool on behaviour and milk yield, eighty-eight lactating buffalo cows equally allocated to two treatments were used. Group WP was provided with a concrete pool of 208 m2, 36 m2/ head + 10 m2 of outdoor and indoor space allowance, respectively, whereas group NP only received 10 m2. Less animals from group WP were observed idling (P<0.05 compared to buffaloes from group NP, whereas subjects provided with a pool were more often involved in investigative activities (locomotion and exploration than cows without access to it (P< 0.01. A higher number of social interactions (sniffing and nuzzling and allogrooming were observed in group WP than in group NP (P< 0.01 and P< 0.05, respectively. The WP buffalo cows exhibited a higher yield of milk than NP subject (P< 0.05, whereas no differences between the two groups were observed for protein and fat contents. The provision of a pool can have beneficial effects on behaviour and milk production of buffaloes.

  6. The role of MC1R gene in buffalo coat color

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Melanocortin-1 receptor (MC1R) plays a major role in pigmentation in many species.To investigate if the MC1R gene is associated with coat color in water buffalo,the coding region of MC1R gene of 216 buffalo samples was sequenced,which included 49 black river buffalo (Murrah and Nili-Ravi),136 swamp buffalo (Dehong,Diandongnan,Dechang,Guizhou,and Xilin) with white and gray body,and 31 hybrid offspring of river buffalo Nili-Ravi (or Murrah) and swamp buffalo.Among the three variation sites found,SNP684 was synonymous,while SNP310 and SNP384 were nonsynonymous,leading to p.S104G and p.I128M changes,respectively.Only Individuals carrying homozygote EBR/EBR were black.The genotype and phenotype analysis of the hybrid offspring of black river buffalo and gray swamp buffalo further revealed that the river buffalo type allele EBR or the allele carrying the amino acid p.104S was important for the full function of MC1R.The in silico functional analysis showed that the amino acid substitutions p.G104S and p.M128I had significant impact on the function of MC1R.Above results indicate that the allele EBR or the allele carrying the amino acid p.104S was associated with the black coat color in buffalo.

    Scientific basis on the quality changes of traditional keema will boost and sustain meat production and utilization in buffalo abundant countries. A programme was undertaken to determine the influence of age and gender on the quality of buffalo meat keema at refrigerator storage (4 ± 1 °C). Buffalo meat keema was evaluated by analyzing the changes in physicochemical, microbiological and sensory attributes. The product characteristics and acceptability of keema were better in spent buffalo group than young male group. The values of pH, TBARS, total aerobic mesophils, coliforms, Lactobacillus, Staphylococcus aureus, anaerobic and psychrophilic counts of buffalo meat keema increased but appearance, flavour, juiciness, tenderness, connective tissue residue and overall acceptability scores decreased with progressing refrigerated storage. The shelf life of refrigerated buffalo meat keema was 18 days with an overall acceptability score ranging from extremely acceptable to moderately acceptable.

  8. The African buffalo parasite Theileria. sp. (buffalo can infect and immortalize cattle leukocytes and encodes divergent orthologues of Theileria parva antigen genes

    Full Text Available African Cape buffalo (Syncerus caffer is the wildlife reservoir of multiple species within the apicomplexan protozoan genus Theileria, including Theileria parva which causes East coast fever in cattle. A parasite, which has not yet been formally named, known as Theileria sp. (buffalo has been recognized as a potentially distinct species based on rDNA sequence, since 1993. We demonstrate using reverse line blot (RLB and sequencing of 18S rDNA genes, that in an area where buffalo and cattle co-graze and there is a heavy tick challenge, T. sp. (buffalo can frequently be isolated in culture from cattle leukocytes. We also show that T. sp. (buffalo, which is genetically very closely related to T. parva, according to 18s rDNA sequence, has a conserved orthologue of the polymorphic immunodominant molecule (PIM that forms the basis of the diagnostic ELISA used for T. parva serological detection. Closely related orthologues of several CD8 T cell target antigen genes are also shared with T. parva. By contrast, orthologues of the T. parva p104 and the p67 sporozoite surface antigens could not be amplified by PCR from T. sp. (buffalo, using conserved primers designed from the corresponding T. parva sequences. Collectively the data re-emphasise doubts regarding the value of rDNA sequence data alone for defining apicomplexan species in the absence of additional data. ‘Deep 454 pyrosequencing’ of DNA from two Theileria sporozoite stabilates prepared from Rhipicephalus appendiculatus ticks fed on buffalo failed to detect T. sp. (buffalo. This strongly suggests that R. appendiculatus may not be a vector for T. sp. (buffalo. Collectively, the data provides further evidence that T. sp. (buffalo. is a distinct species from T. parva.

    2016-07-01

    Buffalo farming has made remarkable progress in productivity mainly because of controlled breeding with artificial insemination (AI) that has proved its worth in breed improvement and breeding managements across the livestock species. Artificial insemination is practiced very little in Europe and East Asian countries with coverage of only 5% buffaloes in Italy, 3.7% in Azerbaijan, 0.3% in Egypt, and 0.1% in Romania although in Bulgaria, 80% buffaloes in large cooperative state farms are subjected to AI. In Turkey, it began in 2002 near Hatay with Italian semen provided by the Food and Agriculture Organization (FAO) Network project. In India, where buffaloes are the most valuable livestock species, research on buffalo specific artificial breeding technologies and adoption of AI by buffalo owners are widely acknowledged. Resultantly, average milk yield of buffaloes in India increased from 3.4 kg in 1992 to 93 to 4.57 kg/day/buffalo in 2009 to 10. In the new millennium, mega projects such as the National Project for Cattle and Buffalo Breeding and the National Dairy Plan were initiated with focus on genetic upgradation of bovine and buffalo population through streamlining AI services and support system in the country. Artificial insemination started in India in the year 1939, and the frozen semen was introduced during late 1960s. During the year 2010 to 11, India produced 63 million bovine frozen semen straws including over one million buffalo semen straws through 49 semen stations. Artificial insemination services are provided through 71,341 AI stations clocking 52 million inseminations with overall conception rate of 35% in bovine and buffalo population. Research is being conducted for improved AI conception rates with synchronization programs and improved frozen-thawed semen quality, and success rates are at par with AI in cattle.

    Trypanosoma theileri is a hemoprotozoan parasite that infects various ruminant species. We investigated the epidemiology of this parasite among cattle and water buffalo populations bred in Sri Lanka, using a diagnostic PCR assay based on the cathepsin L-like protein (CATL) gene. Blood DNA samples sourced from cattle (n=316) and water buffaloes (n=320) bred in different geographical areas of Sri Lanka were PCR screened for T. theileri. Parasite DNA was detected in cattle and water buffaloes alike in all the sampling locations. The overall T. theileri-positive rate was higher in water buffaloes (15.9%) than in cattle (7.6%). Subsequently, PCR amplicons were sequenced and the partial CATL sequences were phylogenetically analyzed. The identity values for the CATL gene were 89.6-99.7% among the cattle-derived sequences, compared with values of 90.7-100% for the buffalo-derived sequences. However, the cattle-derived sequences shared 88.2-100% identity values with those from buffaloes. In the phylogenetic tree, the Sri Lankan CATL gene sequences fell into two major clades (TthI and TthII), both of which contain CATL sequences from several other countries. Although most of the CATL sequences from Sri Lankan cattle and buffaloes clustered independently, two buffalo-derived sequences were observed to be closely related to those of the Sri Lankan cattle. Furthermore, a Sri Lankan buffalo sequence clustered with CATL gene sequences from Brazilian buffalo and Thai cattle. In addition to reporting the first PCR-based survey of T. theileri among Sri Lankan-bred cattle and water buffaloes, the present study found that some of the CATL gene fragments sourced from water buffaloes shared similarity with those determined from cattle in this country.

    Full Text Available Background. The product quality of curry is determined by the food animal source, raw materials and the method of processing. Moreover the scientific information on processing and quality of traditional buffalo meat curry from different groups of buffaloes is not available. This study was undertaken to develop processed curry from different buffalo groups and to compare its quality during storage at ambient and refrigeration temperature. Material and methods. The meat samples were collected from the longissimus dorsi muscle of the carcasses from each group of buffaloes slaughtered according to the traditional halal method. Buffalo meat curry was prepared in a pressure cooker with the standardized formulation. This final product was subjected to evaluation of quality and shelf life. Results. To evaluate the effect of different groups of meat samples on the quality of curry, product yield, pH, proximate composition, water activity (aw, thiobarbituric acid reactive substances (TBARS, calorific value, sensory attributes and microbiological assay were determined The energy of meat curry from young buffaloes was significantly lower than the meat curry from spent animal groups. The overall acceptability of curry decreased significantly during 3 days ambient storage compared to refrigeration storage. Conclusions. Scientific processing by adopting good manufacturing practices and suitable packaging helped greatly to improve the shelf life of the ambient temperature stored buffalo meat curry. Buffalo meat curry from young male group showed better product characteristics and overall acceptability scores than spent buffalo group.

    Full Text Available The particular morphology of buffalo udder is associated to milking difficulties. To better understandthe characteristics of milk ejection in buffaloes, a study was conducted in an intensive farm in Lombardy, Italy. Atotal of 184 milk flow profiles were measured with an electronic flow meter. The results showed that during the first3 minutes of milking 73% of total milk yield was milked; lag time of milk ejection (1.94 min ± 1.57 was very longand increased significantly with the increasing of lactation stage. The overmilking phase has also a long duration(33% of total milking time, on average. Administration of oxytocin before milking did not significantly affect milkflow parameters and machine on-time. The results suggested that proper pre-milking stimulation and prompt clustertakeoff could improve milking efficiency, ensuring good milk letdown and protecting teat conditions.

    The seroprevalence of Neospora caninum was surveyed by an ELISA kit on two water buffalo herds of Southern Italy. Seropositive samples were detected in 47% and 59% of individuals, respectively, thus indicating high level of exposure to the parasite even if the possibility of vertical transmission cannot be excluded. Tissue samples collected from three aborted fetuses from the same herds were investigated for N. caninum presence by PCR assays targeting the 18S and the Nc5 DNA sequences, respectively. Both methods have shown the presence of N. caninum DNA in heart and brain. Sequencing of the Nc5 genomic DNA confirmed the presence of N. caninum in the samples; phylogenetic analysis of the obtained sequences showed high homology among the Neospora recovered from different samples. The present study suggests an important role of N. caninum as a possible abortive agent for water buffaloes.

    Full Text Available Paratuberculosis (Johne’s diseases is responsible for massive economic losses to dairy industry, both in the industrially advanced as well as in the developing countries. To detect its occurrence in cattle and buffaloes locally, blood and tissue samples from clinically weak and grossly suspected slaughtered animals were collected from two abattoirs of Jhang, municipal area, Pakistan. Acid-fast smear staining, gross/histopathology and indirect ELISA were done for the detection of Mycobacterium avium subsp. paratuberculosis (MAP. Total 134 samples illustrating gross pathological lesions were collected, only 11.19% (cattle: 6.67%, buffaloes: 12.5% showed acid fast bacilli through smear staining and were taken as confirmed cases. Thickening of intestines alone was not a reliable indicator of Johne’s disease. Tissue sections from intestines and mesenteric lymph nodes from these acid fast positive animals were stained with hematoxylin & eosin (H&E and Ziehl Neelsen (ZN methods. Sum of (15/134 impression smear staining as well as (15/15 tissue sections of the intestines were found ZN positive, and only 6.7% of impression smears and 100% of tissue sections of mesenteric lymph nodes showed acid fast bacilli. Through ELISA, two cattle and five buffaloes (07/134 gave positive optical densities, while one cattle and seven buffaloes (08/134 were judged as doubtful. It is concluded that infection of MAP can be identified by histopathology and ELISA. The present study was the first record of paratuberculosis among the dairy animals slaughtered at Jhang abattoirs. The objective was to compare different methods for the diagnosis of Johne’s disease.

    Full Text Available Background: Buffaloes are silent heat animals and lacunae in their estrus detection results a substantial economic loss in developing countries. Many advanced tools to aid heat detection have been developed but are neither affordable nor easily interpretable by marginal farmers. Aim: The present investigation was made to develop a cost-effective estrus detection model by combining several known estrus predicting parameters. Materials and Methods: Various signs of estrus were classified under major parameters such as visual, cow behavioral, bull behavioral, biochemical, and gyneco-clinical. Expression of those parameters was observed in buffaloes, and the percentage of positive estrus detection was calculated for each combination of estrus prediction parameters. Results: The present result concludes that the model comprises of five parameters group with several signals with twentysix different combinations. It was observed that the expression of individual combinations and their corresponding estrus detection efficiency varies significantly, i.e., detection efficiency rises as the number of combination increases. Conclusion: Combination of three parameters would provide an estrus detection efficiency >70% and suggested for an easy estrus detection. This would be a cost-effective model for farmers and benefits in enhancing buffalo population/reproduction.

    Full Text Available Marbofloxacin is a synthetic, bactericidal antimicrobial, belonging to the fluoroquinolone group which acts by inhibition of DNA gyrase and those acts by concentration dependant killing mechanism, so high plasma concentration initially is important. This drug is a fluoroquinolone developed exclusively for veterinary use, and exhibit high bactericidal activity against a broad spectrum of aerobic gram-negative, some gram-positive bacteria and Mycoplasma spp. The pharmacokinetic behaviour of marbofloxacin was investigated after intravenous (2 mg/kg in five clinically healthy buffaloes (10 days-old. Plasma concentrations of the marbofloxacin were determined by a HPLC/ u.v. method. After intravenous administration, marbofloxacin in buffaloes was characterized by a AUC = 8,42±3,71 μg·h/ml, a large volume of distribution (Vss=1.59±0.55 L/kg and a long persistence with an elimination half-life (t½λ of 4.6±0,31 h, and MRT 5,90±0,57h. Furthermore, marbofloxacin in buffaloes was characterized by a relatively low total body clearance (Cl of 0.28±0.12 L/kg·h.

    Full Text Available Buffalo milk samples differing significantly for cheese yield values were analysed by 2D electrophoresis in order to outline a protein profile, with specific regards to k-casein fractions. Four buffaloes, two of which showing high cheese yield and two with low cheese yield selected from a group of 135 subjects were chosen for the proteomic analyses. Six main spots in 2D gels were recognized as αs1-, αs2-, β- and k-casein, α-lactoalbumin, β-lactoglobulin. The main visible differences in the 2D gels between buffaloes with high vs. low cheese yield were found in the appearance of the four k-casein spots (spots numbers:20, 19, 16, 18 which differ in the number of phosphorilation and glycosilation. The area and the intensity of the four spots were calculated by using Melanie II (Bio-Rad software. Samples with high cheese yield showed higher value of the by-products: area x intensity of spot 16, correspondent to k-casein with one phosphorilation site, and lower values of spots 19 and 20, of k-casein with more than one phosphorilation site and glycosilated.

    Haemorrhagic septicaemia (HS) is an acute, septicaemic disease of cattle and buffalo of Asia and Africa caused by Pasteurella multocida B:2 or E:2. Buffaloes are believed to be more susceptible than cattle. In this study, 9 buffaloes of 8 months old were divided equally into 3 groups (Groups 1, 3, 5). Similarly, 9 cattle of 8 months old were equally divided into 3 groups (Groups 2, 4, 6). Animals of Groups 1 and 2 were inoculated with PBS while Groups 3 and 4 were inoculated subcutaneously with 10(5) cfu/ml of P. multocida B:2. Animals of Groups 5 and 6 were inoculated intranasally with the same inoculum. Both buffaloes and cattle that were inoculated subcutaneously succumbed to the infection at 16 h and 18 h, respectively. Two buffaloes that were inoculated intranasally (Group 5) succumbed at 68 h while the remaining cattle and buffaloes survived the 72-h study period. Endotoxin was detected in the blood of infected cattle (Group 4) and buffaloes (Groups 3 and 5) prior to the detection of P. multocida B:2 in the blood. The endotoxin was detected in the blood of buffaloes of Group 3 and cattle of Group 4 at 0.5 h post-inoculation while buffaloes of Group 5 and cattle of Group 6 at 1.5 h. On the other hand, bacteraemia was detected at 2.5 h in buffaloes of Group 3 and cattle of Group 4 and at 12 h in buffaloes of Group 5 and cattle of Group 6. Affected cattle and buffaloes showed lesions typical of haemorrhagic septicaemia. These included congestion and haemorrhages in the organs of respiratory, gastrointestinal and urinary tracts with evidence of acute inflammatory reactions. The severity of gross and histopathology lesions in cattle and buffalo calves that succumbed to the infection showed insignificant (p > 0.05) difference. However, inoculated buffalo and cattle that survived the infection showed significantly (p cattle are more resistant to intranasal infection by P. multocida B:2 than buffaloes.

  1. The Olduvai buffalo Pelorovis and the origin of Bos

    2007-09-01

    The origin of the genus Bos is a debated issue. From ˜ 0.5 Ma until historic times, the genus is well known in the Eurasian large mammal assemblages, where it is represented by Bos primigenius. This species has a highly derived cranial anatomy that shows important morphological differences from other Plio-Pleistocene Eurasian genera of the tribe Bovini such as Leptobos, Bison, Proamphibos-Hemibos, and Bubalus. The oldest clear evidence of Bos is the skull fragment ASB-198-1 from the middle Pleistocene (˜ 0.6-0.8 Ma) site of Asbole (Lower Awash Valley, Ethiopia). The first appearance of Bos in Europe is at the site of Venosa-Notarchirico, Italy (˜ 0.5-0.6 Ma). Although the origin of Bos has traditionally been connected with Leptobos and Bison, after a detailed anatomical and morphometric study we propose here a different origin, connecting the middle Pleistocene Eurasian forms of B. primigenius with the African Late Pliocene and early Pleistocene large size member of the tribe Bovini Pelorovis sensu stricto. The dispersal of the Bos lineage in Western Europe during middle Pleistocene times seems to coincide with the arrival of the Acheulean tool technology in this continent.

    Full Text Available Present study evaluates the milk fatty acid (FA composition and cholesterol content of two main Pakistani dairy breeds water buffaloes, i.e. Kundi and Nili-Ravi (n = 25 for each breed. The buffaloes were housed together and received the same diet. The results show a significant variation (P < 0.05 in the FA content of the two breeds. The milk fat of Kundi buffalo was found to contain significantly lower (P < 0.05 amount of saturated fatty acid content than Nili-Ravi buffaloes (66.96 and 69.09 g/100 g. Determined mean monounsaturated fatty acid (MUFA contents (27.62 vs. 25.20 g/100g and total trans fatty acids (3.48 vs. 2.48 were significantly elevated (P < 0.05 in the milk fat of Kundi buffaloes. Amount of fat and conjugated linoleic acid content was higher (P = 0.04 in Kundi buffalo as compared to Nili-Ravi buffaloes (7.00 vs. 7.78 g /100g and 0.80 vs. 0.71g / 100g, while cholesterol content was not different among both breeds ranging from 8.89 – 10.24 mg /dl. Present studies show that in future genetic selection programs along with altered buffalo nutrition may be able to result in optimum levels of various fatty acids in milk.

    Full Text Available Buffalo is indigenous livestock of Asia, classified as beef buffaloes that evolve in Southeast Asia and China and dairy buffaloes exist in Indo-Pakistan and Mediteranian. In Indonesia, beef buffaloes are known as swamp buffalo and there are seven new buffalo breeds namely Pampangan, Sumbawa, Moa, Toraya, Simelue, East Kalimantan and South Kalimantan. Buffaloes are reared in extensive traditional system characterized by low growth rate and reproduction ability due to feed shortage and high inbreeding rate. Feed improvements in female is required to get dry matter intake 2.5-2.7% of body weight (BW that consist of 70% roughage and 30% concentrates, will show a clear sign of estrus. In the male when feed consumption is 2.7-3.5% of BW; it will perform growth rate of 0.6 kg/head/day. Genetic improvement is conducted through selection based on BW in certain ages, reproduction ability and parents without recessive alleles. Distribution of proven bulls and their sperm in outbreeding system would improve the production and reproduction performance, reduce inbreeding level and increase breeding farmer’s income. It is expected that in the long term, the population of buffaloes in Indonesia will increase.

  8. Karyotypic evolution of ribosomal sites in buffalo subspecies and their crossbreed

    Full Text Available Domestic buffaloes are divided into two group based on cytogenetic characteristics and habitats: the "river buffaloes" with 2n = 50 and the "swamp buffaloes", 2n = 48. Nevertheless, their hybrids are viable, fertile and identified by a 2n = 49. In order to have a better characterization of these different cytotypes of buffaloes, and considering that NOR-bearing chromosomes are involved in the rearrangements responsible for the karyotypic differences, we applied silver staining (Ag-NOR and performed fluorescent in situ hybridization (FISH experiments using 18S rDNA as probe. Metaphases were obtained through blood lymphocyte culture of 21 individuals, including river, swamp and hybrid cytotypes. Ag-NOR staining revealed active NORs on six chromosome pairs (3p, 4p, 6, 21, 23, 24 in the river buffaloes, whereas the swamp buffaloes presented only five NOR-bearing pairs (4p, 6, 20, 22, 23. The F1 crossbreed had 11 chromosomes with active NORs, indicating expression of both parental chromosomes. FISH analysis confirmed the numerical divergence identified with Ag-NOR. This result is explained by the loss of the NOR located on chromosome 4p in the river buffalo, which is involved in the tandem fusion with chromosome 9 in this subspecies. A comparison with the ancestral cattle karyotype suggests that the NOR found on the 3p of the river buffalo may have originated from a duplication of ribosomal genes, resulting in the formation of new NOR sites in this subspecies.

  10. Transforming Swamp Buffaloes to Producers of Milk and Meat Through Crossbreeding and Backcrossing

    2009-09-01

    Full Text Available There are two major types of water buffaloes in the world, the riverine type and the swamp type. The total number of Swamp buffalo is 37.6 M and represents 21.8% of the world’s buffalo population. The swamp buffaloes have played a major role in draft animal-dependent farming system. But intensified rice production became more pronounced in irrigated areas and this has led to increased utilization of small farm machineries, displacing significantly the draft buffaloes for land tillage. To some extent, the introduction of tractors for land preparation and transport for corn, sugarcane and other crops in production areas has similar effect. Utilization of the existing population of swamp buffaloes to meet the growing domestic demand for milk and meat, against the background of increasing farm mechanization, is a good reason to transform the huge number of draft animals into producers of milk and meat. According to the UNDP/FAO-assisted project in the Philippines carried from 1982 to 1998, that crossing swamp buffalo and riverine buffaloes, despite the differences in chromosome numbers, is producing crossbreds with high growth rate potentials and milk production abilities several folds over the swamp buffalo parents. The known fact that swamp and riverine buffaloes have different chromosome number, the diploid chromosome number of the swamp buffalo is 48 and that of the river buffalo is 50. When crossbreeding between the 2 buffalo types occur, males and females of the F1 generation are heterozygous for the fusion and are apparently fertile with chromosome 2n = 49. Three-way crossbred hybrids were obtained by (native buffalo x Murrah x Nili Ravi or (native buffalo x Nili Ravi x Murrah. They had two chromosome categories viz. 2n=49 and 2n=50, respectively. Crossbreeding Swamp with Riverine Breed is done for quality beef. Most of the NT produced TenderBuff is farm-bred or purchased from other suppliers as swamp buffalo yearlings and growth out for a

    2016-06-01

    Full Text Available Collagen is widely used for biomedical and pharmaceutical applications due to its excellent biocompatibility, biodegradability and weak antigenicity. However, applicability is limited due to its high cost and probability of disease transmission from the current sources, which are bovine and porcine. In the present study, collagen was extracted from 6 months buffalo skins as alternative save sources. Collagen was characterized by different physico-chemical techniques like ATR-FTIR, Raman, SEM, DSC and amino acids analysis. Proline and hydroxyproline contents of buffalo skin collagen were higher than those of calf skin collagen. Thermal stability of buffalo skin collagen is high with respect to that of calf skin collagen. The obtained buffalo skin collagen shows higher stiffness upon cross-linking with glutaraldehyde. Thus buffalo skin collagen can be used for fabrication of high strength bioactive sponge and sheets for medical applications, like scaffold for tissue engineering, drug delivery and wound dressing system.

    Full Text Available Aim: The present study was carried out to analyze mortality pattern in Murrah buffalo males in National Dairy Research Institute herd. Materials and Methods: Records of 1029 Murrah buffalo males born during the period 1997-2012, at NDRI, Karnal, were analyzed to study mortality pattern in different age groups. The percent of animal disposed from the herd due to different reasons was calculated by proportion using descriptive statistics. Results: The overall percent mortality in 0-1m, 1-2m, 2-3m, 3-6m, 6-18m, 18m-3 yr and >3 year age groups were 17.49, 5.99, 3.34, 5.42, 6.35, 2.59 and 3.93, respectively. The main cause of mortality in 0-1, 1-2, 2-3 and 6-18 m of age groups was respiratory problems (6.61%, 1.79%, 1.06% and 1.97% respectively. Main causes of mortality in age group 3-6 months were general debility (1.57% followed by respiratory and digestive problems (1.22%, miscellaneous (0.87%, liver and urinary problems (0.17%. Mortality could not reveal any consistent trend across different seasons and period of birth. General debility (1.29% followed by toxemia, liver problems and miscellaneous reasons were main causes of mortality in age group 18 m – 3 yr of age. In males above three years of age, general debility (2.81% followed by respiratory problems (1.12% were the main causes of mortality. Conclusion: Intensive health care and management is required for young male buffalo calves especially in hot humid months of rainy season and cold inclement weather conditions in winter months to minimize mortality due to respiratory and digestive problems.

    Five plants are described that could be grown commercially under arid conditions. Once the most valuable component has been obtained from each plant (rubber from guayule; seed oil from jojoba, buffalo gourd, and bladderpod; and resin from gumweed), the remaining material holds potential for useful products as well as fuel. It is difficult to realize the full potential of arid land plants, however, because of the complexities of developing the necessary agricultural and industrial infrastructure simultaneously. To do so, multicompany efforts or cooperative efforts between government and the private sector will be required.

    Mastitis is an infectious disease of the mammary gland that leads to reduced milk production and change in milk composition. Complement component C3 plays a major role as a central molecule of the complement cascade involving in killing ofmicroorganisms, either directly or in cooperation with phagocytic cells. C3 cDNA were isolated, from Egyptian buffalo and cattle, sequenced and characterized. The C3 cDNA sequences of buffalo and cattle consist of 5025 and 5019 bp, respectively. Buffalo and cattle C3 cDNAs share 99% of sequence identity with each other. The 4986 bp open reading frame in buffalo encodes a putative protein of 1661 amino acids—as in cattle—and includes all the functional domains. Further, analysis of the C3 cDNA sequences detected six novel single-nucleotide polymorphisms (SNPs) in buffalo and three novel SNPs in cattle.The association analysis of the detected SNPs with milk somatic cell score as an indicator of mastitis revealed that the most significant association in buffalo was found in the C>A substitution (ss: 1752816097) in exon 27, whereas in cattle it was in the C>T substitution (ss: 1752816085) in exon 12. Our findings provide preliminary information about the contribution of C3 polymorphisms to mastitis resistance in buffalo and cattle.

    Full Text Available Aim: To evaluate the rumen magnet given once a life as a prophylaxis of hardware disease in buffaloes. Materials and Methods: In the present study, 3100 buffaloes were divided into two groups. In group I, 1200 hardware diseased buffaloes were surgically treated with rumenotomy, given reticular magnets and followed up to 7 years for a possible recurrent hardware disease. In group II, 1900 clinically normal buffalo heifers were given rumen magnets orally then followed up to seven years for a possible occurrence of hardware disease. All buffaloes showed signs of hardware disease were treated by rumenotomy. Data were statistically analyzed using chi-square test. Results: Hardware disease was recorded in 110 animals (10.8% and 155 animals (8.9% in groups I and II. The incidence of developing a hardware disease during the first 4 years after the use of magnet was 0% in both groups. Starting from 5th year, a time dependent increase in the proportion of buffaloes developing a hardware disease was noticed in both groups (P 0.05. Conclusion: Administration of a rumen magnet is an effective prophylaxis for hardware disease and reapplication of a second new magnet is recommended four years later in buffaloes at high risk.

    Aim: Anoestrus is one of the most common functional disorders of the reproductive cycle in buffaloes. In spite of technical advancement, there is no single cure for the management of anoestrus. Therefore, the aim of this study was to find out the efficacy of gonadotropic releasing hormone (GnRH) and metabolic hormone for the management of true anoestrus in buffaloes. Materials and Methods: The experimental animals were selected on the basis of history, gyneco-clinical examinations and progesterone estimation. Deworming was done with Fenbendazole and thereafter mineral mixture was given @ 50 g per animal per day for 10 days in all the selected buffaloes before the start of treatment. The selected buffaloes were randomly divided into four groups (n=25). In Group I, buffaloes were administered 20 µg of buserelin intramuscularly. Buffaloes of Group II were administered long-acting insulin @ 0.25 IU/Kg body weight subcutaneously for 5 consecutive days. In Group III, buffaloes were treated with a combination of insulin and buserelin in the above-mentioned doses whereas buffaloes of Group IV were kept as untreated control. Results: The higher oestrus induction (64% vs. 28%) was found in Group III and differed significantly (p<0.05) as compared to control group. The conception rate (69.23% vs. 66.66%) was also found higher in Group III but did not differ significantly among the treated groups. The mean time taken for the onset of oestrus was recorded significantly shorter in insulin (8.80±0.69) and GnRH (7.60±0.92 days) alone and as compared to other (Group III, 14.43±0.83 and Group IV, 20.57±1.69 days) groups. Conclusion: The results of this study indicated better fertility response using Insulin plus Buserelin in true anoestrus buffaloes under field conditions. PMID:27065651

    Full Text Available Anthracene and arsenic contamination concentrations at various depths in the Buffalo River were analyzed in this study. Anthracene is known to cause damage to human skin and arsenic has been linked to lung and liver cancer. The Buffalo River is labelled as an Area of Concern defined by the Great Lakes Water Quality Agreement between Canada and the United States. It has a long history of industrial activity located in its near vicinity that has contributed to its pollution. An ordinary kriging spatial interpolation technique was used to calculate estimates between sample locations for anthracene and arsenic at various depths. The results show that both anthracene and arsenic surface sediment (0–30 cm is less contaminated than all subsurface depths. There is variability of pollution within the different subsurface levels (30–60 cm, 60–90 cm, 90–120 cm, 120–150 cm and along the river course, but major clusters are identified throughout all depths for both anthracene and arsenic.

    Full Text Available A survey to determine the prevalence of bovine tuberculosis caused by Mycobacterium bovis and certain other infectious diseases was conducted on 42 free-ranging African buffaloes, (Syncerus caffer from May to June 1997 in the Queen Elizabeth National Park, Uganda. Using the gamma interferon test, exposure to M. bovis was detected in 21.6 % of the buffaloes. One dead buffalo and an emaciated warthog (Phacochoerus aethiopicus that was euthanased, were necropsied; both had miliary granulomas from which M. bovis was isolated. None of the buffaloes sampled in Sector A of the park, which has no cattle interface, tested positive for bovine tuberculosis (BTB exposure. The prevalence and distribution of BTB does not appear to have changed significantly since the 1960s, but this may be due to fluxes in the buffalo population. Serological testing for foot-and-mouth disease (FMD demonstrated positive exposure of 57.1% of the buffaloes sampled, with types A, O and SAT 1-3, which is the first known report of FMD antibodies to A and O types in free ranging African buffaloes. Foot-and-mouth disease virus types SAT 1 and SAT 3 were isolated from buffalo probang samples. Two percent of the buffaloes had been exposed to brucellosis. None of the buffaloes tested had antibodies to rinderpest, leptospirosis or Q fever.

    It was reported that buffalo is a low susceptibility species resisting to transmissible spongiform encephalopathies (TSEs) (same as rabbits, horses, and dogs). TSEs, also called prion diseases, are invariably fatal and highly infectious neurodegenerative diseases that affect a wide variety of species (except for rabbits, dogs, horses, and buffalo), manifesting as scrapie in sheep and goats; bovine spongiform encephalopathy (BSE or "mad-cow" disease) in cattle; chronic wasting disease in deer and elk; and Creutzfeldt-Jakob diseases, Gerstmann-Sträussler-Scheinker syndrome, fatal familial insomnia, and Kulu in humans etc. In molecular structures, these neurodegenerative diseases are caused by the conversion from a soluble normal cellular prion protein (PrP(C)), predominantly with α-helices, into insoluble abnormally folded infectious prions (PrP(Sc)), rich in β-sheets. In this article, we studied the molecular structure and structural dynamics of buffalo PrP(C) (BufPrP(C)), in order to understand the reason why buffalo is resistant to prion diseases. We first did molecular modeling of a homology structure constructed by one mutation at residue 143 from the NMR structure of bovine and cattle PrP(124-227); immediately we found that for BufPrP(C)(124-227), there are five hydrogen bonds (HBs) at Asn143, but at this position, bovine/cattle do not have such HBs. Same as that of rabbits, dogs, or horses, our molecular dynamics studies also revealed there is a strong salt bridge (SB) ASP178-ARG164 (O-N) keeping the β2-α2 loop linked in buffalo. We also found there is a very strong HB SER170-TYR218 linking this loop with the C-terminal end of α-helix H3. Other information, such as (i) there is a very strong SB HIS187-ARG156 (N-O) linking α-helices H2 and H1 (if mutation H187R is made at position 187, then the hydrophobic core of PrP(C) will be exposed (L.H.

This study was carried out in 4 Iraqi South-central governorates using 596 pre-mating and 628 pregnant buffaloes (during the last two months of gestation. Pre-mating buffaloes were divided randomly into 496 concentrate-supplemented buffaloes (Flushing and 100 control ones. Additionally, pregnant buffaloes were also divided into 528 concentrate- supplemented buffaloes (Steaming up and 100 controls. Each buffalo within the flushing and steaming up groups were fed daily on 7 Kg of concentrate diet (13% crude protein and 1.70 Mcal of net energy for 60 days. The control buffaloes were nourished only on low-quality roughages of the area and wheat bran. Higher estrus (+15%, P<0.01, pregnancy (+23.8%, P<0.05 and calving rates (+30.8%, P<0.01 were observed in concentrate-supplemented buffaloes as compared with controls. An obvious increase in (P<0.05 calving rate (+14.7%, daily milk yield (+44.8% and calf birth weight (+25.6% were noted in steaming up buffaloes in comparison with control buffaloes. Results indicated that improvement in feeding schedule of Iraqi buffaloes during pre-mating and late gestation periods enhanced the reproductive performance and increased milk production of subsequent lactation and calf birth weight. These improvements increased owner income ($174=209,000 Iraqi dinar /buffalo from the sale of meat and milk.

    Theileria parva is the causative agent of Corridor disease in cattle in South Africa. The African buffalo (Syncerus caffer) is the reservoir host, and, as these animals are important for eco-tourism in South Africa, it is compulsory to test and certify them disease free prior to translocation. A T. parva-specific real-time polymerase chain reaction (PCR) test based on the small subunit ribosomal RNA (18S rRNA) gene is one of the tests used for the diagnosis of the parasite in buffalo and cattle in South Africa. However, because of the high similarity between the 18S rRNA gene sequences of T. parva and Theileria sp. (buffalo), the latter is also amplified by the real-time PCR primers, although it is not detected by the T. parva-specific hybridization probes. Preliminary sequencing studies have revealed a small number of sequence differences within the 18S rRNA gene in both species but the extent of this sequence variation is unknown. The aim of the current study was to sequence the 18S rRNA genes of T. parva and Theileria sp. (buffalo), and to determine whether all identified genotypes can be correctly detected by the real-time PCR assay. The reverse line blot (RLB) hybridization assay was used to identify T. parva and Theileria sp. (buffalo) positive samples from buffalo blood samples originating from the Kruger National Park, Hluhluwe-iMfolozi Park, the Greater Limpopo Transfrontier Park, and a private game ranch in the Hoedspruit area. T. parva and Theileria sp. (buffalo) were identified in 42% and 28%, respectively, of 252 samples, mainly as mixed infections. The full-length 18S rRNA gene of selected samples was amplified, cloned and sequenced. From a total of 20 sequences obtained, 10 grouped with previously published T. parva sequences from GenBank while 10 sequences grouped with a previously published Theileria sp. (buffalo) sequence. All these formed a monophyletic group with known pathogenic Theileria species. Our phylogenetic analyses confirm the

    Strict control measures apply to movement of buffalo in South Africa including testing for Theileria parva, the causative agent of Corridor disease in cattle. The official test is a real-time hybridization PCR assay that amplifies the 18S rRNA V4 hyper-variable region of T. parva, T. sp. (buffalo) and T. sp. (bougasvlei). Mixed infections with the latter organisms affect diagnostic sensitivity due to PCR suppression. While the incidence of mixed infections in the Corridor disease endemic region of South Africa is significant, little information is available on the specific distribution and prevalence of T. sp. (buffalo) and T. sp. (bougasvlei). Specific real-time PCR assays were developed and a total of 1211 samples known to harbour these parasites were screened. Both parasites are widely distributed in southern Africa and the incidence of mixed infections with T. parva within the endemic region is similar (∼25-50%). However, a significant discrepancy exists in regard to mixed infections of T. sp. (buffalo) and T. sp. (bougasvlei) (∼10%). Evidence for speciation between T. sp. (buffalo) and T. sp. (bougasvlei) is supported by phylogenetic analysis of the COI gene, and their designation as different species. This suggests mutual exclusion of parasites and the possibility of hybrid sterility in cases of mixed infections.

    The objectives of this study were to determine the individual and herd-level prevalence and genotype of Cryptosporidium and to identify putative risk factors associated with Cryptosporidium spp. infections in water buffaloes in northeast Thailand. Fecal samples from 600 water buffaloes of 287 farms in six provinces were collected and tested using DMSO-modified acid-fast staining and polymerase chain reaction. The overall prevalence of Cryptosporidium infections in buffaloes was 5.7 and 8.7% among individual animals and herds, respectively. The provinces with highest infected Cryptosporidium were located in the Sakon Nakhon Basin in the northern part of the region. In addition, higher herd prevalence was observed among farms with more than five buffaloes (30%) than those with five or less animals (16.2%). Thirty (88.2%) of the 34 Cryptosporidium-positive samples were Cryptosporidium parvum and four (11.8%) were Cryptosporidium ryanae.

    Full Text Available The present study was undertaken to see the effect of mastitic pathogens on the blood and milk counts of Murrah buffaloes. Milk and blood samples were collected from 9 mastitic Murrah buffaloes. The total leucocyte Counts (TLC and Differential leucocyte counts (DLC in blood were within normal range and there was a non-significant change in blood counts irrespective of different mastitic pathogens. Normal milk quarter samples had significantly (P<0.01 less Somatic cell counts (SCC. Lymphocytes were significantly higher in normal milk samples, whereas infected samples had a significant increase (P<0.01 in milk neutrophils. S. aureus infected buffaloes had maximum milk SCC, followed by E. coli and S. agalactiae. Influx of neutrophils in the buffalo mammary gland was maximum for S. agalactiae, followed by E.cli and S. aureus. The study indicated that level of mastitis had no affect on blood counts but it influenced the milk SCC of normal quarters.

    2010-02-01

    Full Text Available Composition and physico-chemical properties of buffalo and cow milks were compared at their initial pH and during chemical acidification. As compare to cow milk, buffalo milk was richer in caseins and minerals such as Ca, Mg and Pi. Along with these differences, the capacity of buffalo milk to be acidified named buffering capacity was also higher than cow milk. The pH decrease induced aggregation of caseins at their isoelectric pH and solubilisations of Ca and Pi were significant for both milks. For both species, these molecular changes were qualitatively similar but quantitatively different. These differences suggested that the acidification process in dairy technology which is well established for cow milk can not be directly extrapolated to buffalo milk and some adaptations are necessary.

    Faecal samples were collected from 500 cattle and 385 buffaloes belonging to backyard farmers from 24 villages in the province of Bukidnon, Mindanao, the Philippines. Strongyle nematode infections were studied on these samples by faecal egg counts and infective larvae differentiation. The effects of animal species and age on the prevalence and intensity of infections were studied. The overall prevalence of strongyle infection was 53% for cattle and 28% for buffaloes. The prevalence decreased with increasing age in both animal species. Faecal egg counts were significantly lower in buffaloes than in cattle. Adult animals had lower egg counts than calves. This age effect was most pronounced in buffaloes. Six genera of strongyle nematodes were identified from the faecal cultures in both animal species, Mecistocirrus, Haemonchus, Trichostrongylus, Cooperia, Bunostomum and Oesophagostomum. The distribution of larvae did not vary much with age.

    Full Text Available The amino acid content of bulked buffalo milk, collected from 130 buffaloes reared at a buffalo farm in the settlement of Dimitrievo, Stara Zagora region, was investigated during the period January-April 2006. The activation of the lactoperoxidase system (LPS was done by supplementation of sodium percarbonate, providing 16 ppm active oxygen and 10 ppm thiocyanate to 1 l of milk. The amino acid content was assayed by an amino acid analyzer. It was found out that the total content of amino acids in inactivated milk was insignificantly lower than that in activated one. More considerable increase was established for the amino acids valine, methionine, and lysine, but the differences were not statistically significant. The total amount of essential amino acids was higher in the milk with chemically activated LPS. The limiting essential amino acid in the studied buffalo milk was methionine.

    Full Text Available A study entitled “Decomposition analysis of buffalo production in Buldana District was undertaken to ascertain the technological changes in term of breeding, feeding, housing, milking and calf management practices of buffalo. The path coefficient analysis of this study clearly demonstrated that daily milk production in buffaloes was influenced substantially by a single factor i.e management index. A combination of all the management practices in the form of overall management status on the rearing were responsible to influence the daily milk yield. However, rearing of good potential animals, feeding of sufficient amounts of dry and green fodder with required amount of concentrates to fulfill the nutritional requirements could favour the milk production in buffaloes. All these factors exhibited positive direct effect on milk production. The indirect effects were also found in positive direction, resulting a positive significant correlation for these factors.

    Relative susceptibility to fluoride (F) toxicosis in the form of osteo-dental fluorosis was observed in an observational survey of 2,747 mature and 887 immature domestic animals of diverse species living in areas with naturally fluoridated (>1.5 ppm F) drinking water. These animals included buffaloes (Bubalus bubalis), cattle (Bos taurus), camels (Camelus dromedarius), donkeys (Equus asinus), horses (Equus caballus), goats (Capra hircus), and sheep (Ovis aries). Of these mature and immature animals, 899 (32.7 %) and 322 (36.3 %) showed evidence of dental fluorosis with varying grades, respectively. Their incisor teeth were stained with light to deep brownish color. On clinical examination, 31.2 % mature and 10.7 % immature animals revealed periosteal exostoses, intermittent lameness, and stiffness of tendons in the legs as signs of skeletal fluorosis. The maximum susceptibility to fluoride toxicosis was found in bovines (buffaloes and cattle) followed by equines (donkeys and horses), flocks (goats and sheep), and camelids (camels). The bovine calves were found to be more sensitive and highly susceptible to F toxicosis and revealed the maximum prevalence (92.2 %) of dental fluorosis. This indicates that bovine calves are less tolerant and give early sign of F poisoning (dental fluorosis) and therefore, they can be considered as bio-indicators for fluoridated water as well as for endemicity of osteo-dental fluorosis. Causes for variation in susceptibility to F toxicosis (fluorosis) in various species of domestic animal are also discussed.

    Full Text Available The cause of zoonotic schistosomiasis in the Philippines is Schistosoma japonicum, which infects up to 46 mammalian hosts, including humans and bovines. In China, water buffaloes have been identified as major reservoir hosts for schistosomiasis japonica, contributing up to 75% of human transmission. In the Philippines, water buffaloes (carabao; Bubalus bubalis carabanesis have, historically, been considered unimportant reservoirs. We therefore revisited the possible role of bovines in schistosome transmission in the Philippines, using the recently described formalin-ethyl acetate sedimentation (FEA-SD technique and a qPCR assay to examine fecal samples from 153 bovines (both carabao and cattle from six barangays in Northern Samar. A high prevalence of S. japonicum was found using qPCR and FEA-SD in both cattle (87.50% and 77.08%, respectively and carabao (80.00% and 55.24%, respectively. The average daily egg output for each bovine was calculated at 195,000. High prevalence and infection intensity of F. gigantica was also found in the bovines by qPCR and FEA-SD (95.33% and 96.00%, respectively. The identification of bovines as major reservoir hosts for S. japonicum transmission suggests that bovine treatment and/or vaccination, as one becomes available, should be included in any future control program that aims to reduce the disease burden due to schistosomiasis in the Philippines.

    Signaling Lymphocyte Activation Molecule-SLAM (CD150) molecule has been reported as a putative receptor for most morbilliviruses for their respective host species. In this study, we determined the complete nucleotide sequence of the gene coding for the morbillivirus receptor-SLAM from the four species, namely, goat (Capra hircus), sheep (Ovis aries), Indian cattle (Bos indicus), and buffalo (Bubalus bubalis). The nucleotide (nt) open reading frame sequence of SLAM gene in all the four species studied was 1017 nucleotides in length encoding a polypeptide of 339 amino acids (aa), similar to Bos taurus, but different from canine, human, marmoset, and mouse SLAM, which were 1029, 1008, 1011, and 1032 nts, respectively, in length, and coding for 343, 336, 337, and 344 aa, respectively. Sequence analysis revealed 96.3-98.5% and 92.9-96.8% identities among the four species at the nt and aa level, respectively. Sequence diversity at aa level between various species revealed that the critical functional region of SLAM protein among different species is relatively conserved, thereby facilitating this molecule to act as a receptor for morbillivirus. Phylogenetic relationship based on the aa sequences of SLAM protein revealed that caprine, ovine, cattle, and buffalo fall under a defined cluster but caprine SLAM is more closely related to ovine, followed by bovine.

    Fasciola gigantica and aspermic (hybrid) Fasciola flukes are thought to be distributed in Southeast Asian countries. The objectives of this study were to investigate the distribution of these flukes from unidentified ruminants in western Java, Indonesia, and to determine their distribution history into the area. Sixty Fasciola flukes from western Java were identified as F. gigantica based on the nucleotide sequences of the nuclear phosphoenolpyruvate carboxykinase (pepck) and DNA polymerase delta (pold) genes. The flukes were then analyzed phylogenetically based on the nucleotide sequence of the mitochondrial NADH dehydrogenase subunit 1 (nad1) gene, together with Fasciola flukes from other Asian countries. All but one F. gigantica fluke were classified in F. gigantica haplogroup C, which mainly contains nad1 haplotypes detected in flukes from Thailand, Vietnam, and China. A population genetic analysis suggested that haplogroup C spread from Thailand to the neighboring countries including Indonesia together with domestic ruminants, such as the swamp buffalo, Bubalus bubalis. The swamp buffalo is one of the important definitive hosts of Fasciola flukes in Indonesia, and is considered to have been domesticated in the north of Thailand. The remaining one fluke displayed a novel nad1 haplotype that has never been detected in the reference countries. Therefore, the origin of the fluke could not be established. No hybrid Fasciola flukes were detected in this study, in contrast to neighboring Asian countries.

    Full Text Available Insulin plays an important role in maintaining the blood glucose level of the body. The β-cells of pancreas produce insulin in the form of precursor that is preproinsulin. The gene of preproinsulin provides an interesting system for addressing question related to molecular evolution. Recombinant DNA technology has made it possible to isolate and sequence the chromosomal genes coding for unique protein products. Although preproinsulin of various organism has been isolated and cloned, but there is no report from buffalo (Bubalus bubalis that is our major livestock. The genomic DNA of buffalo was isolated using Laura-Lee-Boodram method. The part of preproinsulin gene (596bp and 520bp using BPPI-UPS and bpiful_F as forward and BC1-C as reverse primer was amplified. Cloning of amplified fragments of gene were performed in pCR 2.1 vector. Positive clones were screened on the basis of blue white selection. The band obtained on 596bp and 520bp after colony PCR confirmed the successful cloning of preproinsulin gene in pCR 2.1 vector.

In the span of weeks, three studies have appeared describing the genetic characterization and phylogenetic analyses of malaria parasites from African antelope (Cephalophus spp.) and goat (Capra aegagrus hircus), Asian water buffalo (Bubalus bubalis), and North American white-tailed deer (Odocoileus virginianus). Here we unify the contributions from those studies with the literature on pre-molecular characterizations of ungulate malaria parasites, which are largely based on surveys of Giemsa-reagent stained blood smears. We present a phylogenetic tree generated from all available ungulate malaria parasite sequence data, and show that parasites from African duiker antelope and goat, Asian water buffalo and New World white-tailed deer group together in a clade, which branches early in Plasmodium evolution. Anopheline mosquitoes appear to be the dominant, if not sole vectors for parasite transmission. We pose questions for future phylogenetic studies, and discuss topics that we hope will spur further molecular and cellular studies of ungulate malaria parasites.

    Full Text Available Bovine tuberculosis (BTB is a chronic, highly infectious disease that affects humans, cattle and numerous species of wildlife. In developing countries such as South Africa, the existence of extensive wildlife-human-livestock interfaces poses a significant risk of Mycobacterium bovis transmission between these groups, and has far-reaching ecological, economic and public health impacts. The African buffalo (Syncerus caffer, acts as a maintenance host for Mycobacterium bovis, and maintains and transmits the disease within the buffalo and to other species. In this study we aimed to investigate genetic susceptibility of buffalo for Mycobacterium bovis infection. Samples from 868 African buffalo of the Cape buffalo subspecies were used in this study. SNPs (n = 69, with predicted functional consequences in genes related to the immune system, were genotyped in this buffalo population by competitive allele-specific SNP genotyping. Case-control association testing and statistical analyses identified three SNPs associated with BTB status in buffalo. These SNPs, SNP41, SNP137 and SNP144, are located in the SLC7A13, DMBT1 and IL1α genes, respectively. SNP137 remained significantly associated after permutation testing. The three genetic polymorphisms identified are located in promising candidate genes for further exploration into genetic susceptibility to BTB in buffalo and other bovids, such as the domestic cow. These polymorphisms/genes may also hold potential for marker-assisted breeding programmes, with the aim of breeding more BTB-resistant animals and herds within both the national parks and the private sector.

    Studies reporting the effects of oxytocin on the health of lactating animals are lacking and still no such data is available on Nili Ravi buffalo, the most prominent Asian buffalo breed. The present study was conducted to investigate the effect of oxytocin on physiological and metabolic parameters of lactating Nili Ravi buffaloes. Healthy lactating buffaloes (n = 40) of recent calving were selected from a commercial dairy farm situated in the peri-urban area of district Faisalabad, Pakistan. These buffaloes were randomly allocated to two equal groups viz experimental and control, comprising 20 animals each. Twice-a-day (morning and evening) milking practice was followed. The experimental and control buffaloes were administered subcutaneously with 3 mL of oxytocin (10 IU/mL) and normal saline respectively, prior to each milking. Serum biochemical profile including glucose, total cholesterol (tChol), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), total proteins (TP), C-reactive protein (CRP), liver enzymes aspartate transaminase (AST), alanine transaminase (ALT), and metabolic hormones triiodothyronine (T₃) and thyroxine (T₄) were studied. Results revealed significantly higher (P ≤ 0.01) levels of glucose, total cholesterol, LDL-C, triglycerides, total proteins, and C-reactive protein in experimental (oxytocin-injected) lactating buffaloes compared to control group. Liver enzymes AST and ALT as well as serum T₄ concentration was significantly higher (P ≤ 0.01) in oxytocin-injected lactating buffaloes as compared to control animals. It was concluded that oxytocin had the key role in increasing the metabolic parameters and hormones, resulting in the optimization of production. But, at the same time, it may pose a threat to the animal health.

    Full Text Available Seasonality of calving and its association with milk yield was analyzed in Nili-Ravi buffaloes and compared with Sahiwal cattle and Sahiwal (x Friesian or Jersey crossbreds. Records of 9,174 lactations of Nili-Ravi buffaloes from four institutional herds, 22,499 lactations from five Sahiwal herds and 656 lactations from a crossbred cattle herd were used for comparison. All the herds were located in Punjab province of Pakistan where environment is tropical. Month of calving was important source of variation in lactation milk yield of Nili- Ravi buffaloes and Sahiwal cattle but not in crossbred cattle (due to wide variation. Interactions of month of calving with parity as well as with herd were significant (P<0.01 both for buffaloes and Sahiwal cattle. First parity lactation milk yield averaged 1813±23.2, 1305±11.0 and 2459±81.8 litres while averages of later parity animals were 1926±19.0, 1527±7.6 and 2842±54.2 litres for Nili-Ravi buffaloes, Sahiwal and crossbred cattle, respectively. Milk yield pattern in crossbreds was more similar to buffaloes than to Sahiwals. Yet, crossbreds calving in June produced statistically similar but numerically higher lactation milk yield (2950±170 litres than other months but this was not true for buffaloes and Sahiwals. Buffaloes and Sahiwal cows calving in January-February produced better lactation yields than those calving in other months. Different pattern of milk yield in the three dairy species can be used advantageously for sustainable milk supply throughout the year.

    Water buffaloes are thought to be the reservoir hosts for several hemoprotozoan parasites that infect cattle. In the present study, we surveyed Sri Lankan bred water buffaloes for infections with Babesia bovis, Babesia bigemina, Theileria annulata, and Theileria orientalis using parasite-specific PCR assays. When 320 blood-derived DNA samples from water buffaloes reared in three different districts (Polonnaruwa, Mannar, and Mullaitivu) of Sri Lanka were PCR screened, B. bovis, B. bigemina, and T. orientalis were detected. While T. orientalis was the predominant parasite (82.5%), low PCR-positive rates were observed for B. bovis (1.9%) and B. bigemina (1.6%). Amplicons of the gene sequences of the Rhoptry Associated Protein-1 (RAP-1) of B. bovis, the Apical Membrane Antigen-1 (AMA-1) of B. bigemina, and the Major Piroplasm Surface Protein (MPSP) of T. orientalis were compared with those characterized previously in Sri Lankan cattle. While the B. bigemina AMA-1 sequences from water buffaloes shared high identity values with those from cattle, B. bovis RAP-1 sequences from water buffaloes diverged genetically from those of cattle. For T. orientalis, none of the MPSP sequence types reported previously in Sri Lankan cattle (types 1, 3, 5, and 7) were detected in the water buffaloes, and the MPSP sequences analyzed in the present study belonged to types N1 or N2. In summary, in addition to reporting the first PCR-based survey of Babesia and Theileria parasites in water buffaloes in Sri Lanka, the present study found that the predominant variants of water buffalo-derived B. bovis RAP-1 and T. orientalis MPSP sequences were different from those previously described from cattle in this country.

    Full Text Available A project was planned to study some physical characteristics of oestrus mucus and conception rates in repeat breeder buffaloes after different treatments. For this purpose 60 adult buffaloes with history of repeat breeding were used. Mucus samples from these animals were collected during heat and studied for colour, consistence, pH and fern pattern. Experimental buffaloes were randomly divided into four equal groups A, B, C and D. In buffa1oes of group A, GnRH was given immediately after insemination. In group B antibiotic infusion was given 24 hr after insemination. In animals of group C, insemination was done in the uterine horn ipsilateral to ovary bearing mature graafian follicle. Animals of group D were inseminated in the uterine body and served as control. The results indicated that oestrus mucus was transparent in 55.0%, translucent in 38.33% and whitish in 6.67% buffaloes. The consistency of mucus was viscous in 38.33%, thin in 50.0% and thick in, 11.67% repeat breeder buffaloes. Mean pH of oestrus mucus was 7.49 ± 0.35. Fren pattern was very characteristic in 6.67% characteristic in 48.33% and less characteristic in 45.0% buffaloes. The conception rates in animals of group B were significantly higher ( P<0.05 than those of group A, C or D; the differences in conception rates among buffaloes of the latter three groups were non significant. It was concluded that post-insemination antibiotic infusion may be used to improve conception rates in repeat breeder buffaloes.

    Full Text Available Physiological responses of the buffalo Syncerus caffer culled with succinyldicholine (Scoline1 are reported and it is pointed out that a number of stressors are responsible for the observed changes in blood composition. The results are compared to those obtained in a pilot experiment from buffaloes culled with Scoline and hexamethonium, a ganglion blocker. Further investigation of the effects of hexamethonium may prove it to be of benefit to animals culled with Scoline.

    A comparative study on the prevalence of Anaplasma parasite was conducted on ticks carrying buffaloes and cattle.Five hundred blood samples of both animals (250 of each) were collected during February, March and April. Thin blood smears on glass slides were made, fixed in 100% methyl alcohol and examined. Microscopic examination revealed that 205 (41%) animals had Anaplasma parasites, out of which 89, 44 and 72 animals had Anaplasma marginale, Anaplasma centrale and mixed infection respectively. Infected buffaloes and cattle were 75 and 130 respectively. The infection in female was 53 and 92 in buffaloes and cattle respectively. Twenty-two and 92 blood samples of male were found positive in buffaloes and cattle respectively. Comparative study revealed that the cattle were 26.82% more susceptible than buffaloes. The parasite prevailing percentage in female of both animals was slightly higher than that of the male. This investigation was aimed at studying the comparative prevalence of Anaplasma parasite in tick carrying buffaloes and cattle.

    Objective: To determine the effect of equine chorionic gonadotropin (eCG) and controlled internal drug releasing (CIDR) on estrus response, ovulation and pregnancy rate in Nili-Ravi buffaloes under field condition. Methods: Twenty anestrous buffaloes with more than 150 days postpartum were used in this study. To confirm anestrous condition, ovarian status and serum progesterone concentration were determined before the start of study. Buffaloes were randomly divided into eCG (n=10) and CIDR (n=10) groups. eCG group were treated with eCG (Chronogest 1000 I.U. i.m.), while CIDR group received CIDR devices for 7 days. All buffaloes in CIDR group were injected PGF2α (0.25 ug/mL; 2 mL; i.m.) one day before CIDR removal. Buffaloes were observed for estrus visually and were inseminated with frozen-thawed semen at detected estrus. Ovulation was confirmed by presence of CL 12 day post AI. Pregnancy diagnosis was done 50 days post AI. Results: Estrus response, ovulation rate and pregnancy rate were similar (P>0.05) among eCG and CIDR groups (90% vs. 80%; 78% vs. 75% and 50% vs. 60% respectively). Conclusion: It is concluded that both CIDR and eCG protocols are effective and promising remedies for the anestrous buffaloes under commercial as well as under field conditions.

    The DRB3 gene is an MHC class II gene that has a high degree of polymorphism with more than 100 alleles described in cattle. This variation contributes to differences among individuals in immune responsiveness and disease resistance. In this study, we searched for allelic variants in exon 2 of the DRB3 gene in 80 river buffaloes of three breeds in Brazil using a PCR-RFLP technique. The PCR product showed genetic polymorphism when digested with RsaI, PstI or HaeIII restriction enzymes. In total, 16 restriction patterns were identified: nine restriction patterns and 16 genotypes were found with RsaI; four restriction patterns and nine genotypes were found with HaeIII; and, three restriction patterns and four genotypes were found with PstI. Three RFLP patterns were exclusive to Jafarabadi buffaloes (RsaI-b, RsaI-c and RsaI-f) and three others were only observed in Mediterranean buffaloes (RsaI-g, RsaI-h and PstI-y). Jafarabadi buffaloes had a larger number of RFLP patterns than Mediterranean and Murrah breeds. The analysis showed that the DRB3 exon 2 was highly polymorphic, with the highest degree of polymorphism in Mediterranean buffaloes. This study provides the first assessment of allelic variation among three different buffalo breeds from Brazil and provides a basis for further investigations into the association between the DRB3 alleles and disease resistance.

    Full Text Available Expansion of rubber tree plantations and agricultural mechanization caused a decline of swamp buffalo numbers in the Naban River National Nature Reserve (NRNNR, Yunnan Province, China. We analysed current use of buffaloes for field work and the recent development of the regional buffalo population, based on interviews with 184 farmers in 2007/2008 and discussions with 62 buffalo keepers in 2009. Three types of NRNNR farms were distinguished, differing mainly in altitude, area under rubber, and involvement in livestock husbandry. While pig based farms (PB; n=37 have abandoned buffalo keeping, 11% of the rubber based farms (RB; n=71 and 100% of the livestock-corn based farms (LB; n=76 kept buffaloes in 2008. Herd size was 2.5 +/-1.80 (n=84 buffaloes in early 2008 and 2.2 +/-1.69 (n=62 in 2009. Field work on own land was the main reason for keeping buffaloes (87.3 %, but lending work buffaloes to neighbours (79.0% was also important. Other purposes were transport of goods (16.1%, buffalo trade (11.3% and meat consumption (6.4%. Buffalo care required 6.2 +/-3.00 working hours daily, while annual working time of a buffalo was 294 +/-216.6 hours. The area ploughed with buffaloes remained constant during the past 10 years despite an expansion of land cropped per farm. Although further replacement of buffaloes by tractors occurs rapidly, buffaloes still provide cheap work force and buffer risks on poor NRNNR farms. Appropriate advice is needed for improved breeding management to increase the efficiency of buffalo husbandry and provide better opportunities for buffalo meat sale in the region.

    Full Text Available The study was conducted on in-vitro fertility assessment of frozen thawed semen collected from Kundhi buffalo bull maintained at Department of Animal Reproduction, Faculty of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University Tandojam. Before freezing of semen, each ejaculate was assessed for volume, sperm concentration, mass activity and moss motility percentage. Twenty semen samples having motility 60% or above were frozen for post-thaw assessment. Frozen thawed semen was incubated at 250C for 5 hours and examined for progressive linear motility and live dead sperm count. The mean volume, mass activity, moss motility percentage sperm concentrations and pH of the semen were found to be 2.79±0.217 ml, 2.85±0.111, 71.75±2.621, 11.35±1.255 millions/ml and 5.8185±0.092 respectively of fresh semen. No significant difference was found between the parameters except pH, which was significantly different between the bulls. The mean sperm motility percentage and live dead sperm count % of Kundhi buffalo bull semen was found to be 20.46±1.62 and 6.9± 0.2% for frozen semen. A significant (P< 0.05 difference was found between the bulls for post-thaw motility percentage. It was found that at 01 hour incubation, 43.25±2.95% of sperms were motile having 11.78±0.28 % dead sperm count. It was gradually decline from 0 to 5 hours incubation, After 5 hours, all sperms were found dead. It is concluded that sperms maintaining long term motility and having less live dead sperms count were considered suitable for artificial insemination.

The B. megapotamica used for the experiment was harvested on a farm where a recent spontaneous outbreak of poisoning caused by such plant had occurred. Clinical signs appeared 4-20 hours and 4 buffaloes died 18-49 hours after the ingestion of the plant. Clinical signs were apathy, anorexia, and watery diarrhea, fever, colic, drooling, muscle tremors, restlessness, laborious breathing and ruminal atony, and dehydration. The most consistent gross findings were restricted to the gastrointestinal (GI tract consisted of varying degrees of edema and reddening of the mucosa of the forestomach. Histopathological findings consisted of varying degrees of necrosis of the epithelial lining of the forestomach and of lymphocytes within lymphoid organs and aggregates. Fibrin thrombi were consistently found in sub-mucosal vessels of the forestomach and in the lumen of hepatic sinusoids. It is suggested that dehydration, septicemia and disseminated intravascular coagulation participate in the pathogenesis of the intoxication and play a role as a cause of death. A subsample of B. megapotamica var. weirii was frozen-dried and ground and analyzed using UHPLC (Ultra High Performance Liquid Chromatography with high resolution Time of Flight mass spectrometry and tandem mass spectrometry, it was shown that the plant material contained at least 51 different macrocyclic trichothecenes at a total level of 1.1-1.2mg/g. About 15-20% of the total trichothecenes contents was found to be monosaccharide conjugates, with two thirds of these being glucose conjugates and one third constituted by six aldopentose conjugates (probably xylose, which has never been reported in the literature.

    Full Text Available Aim of this study was to estimate the average intercalving period of a buffalo herd/population, by using the percentage of subjects that are able to conceive within 90 days post-partum, and that, consequently, have an intercalving period lower than 400 days, in order to give a precocious judgment on its fertility. A total number of 8,845 intercalving periods were recorded in 4 farms and 4 Provinces of Campania and Lazio Regions. In all the farms the out of breeding season mating technique was adopted and a constant diet was administered throughout the year. Values were grouped for primiparous and pluriparous buffaloes and were divided in four calving periods: January-March; April-June; July-September; October-December. Within each group/farm ANOVA was performed and the means were analysed by t Student test. In each group the mean value and the percentage of subjects with an intercalving period lower than 400 days (% < 400 days were calculated and the regression analysis was carried out between the values of the intercalving periods and the % < 400 days. Finally, an all-in regression analysis was performed by using the data of 55 groups, excluding those with less than 25 values. The regression analysis between % < 400 days and the mean value of the intercalving period was always significant, except in one case. The comparison between the real values and those calculated allows to affirm that, if the percentage of subjects with an intercalving period lower than 400 days is higher than 50%, an intercalving period lower than 450 days will be probably recorded.

    The abundance and distribution of parasitic helminths in populations of African buffaloes, Syncerus caffer, have not been well documented. A total of 28 buffaloes of different ages and sexeswere sampled in the Kruger National Park, South Africa, for nematodes of the small intestine. Three nematode species were identified, namely Cooperia fuelleborni, Cooperia hungi and Trichostrongylus deflexus, with C. hungi being a new country record for African buffalo in South Africa. The overall prevalence was 71%and the average number of worms was 2346 (range: 0-15 980). This is a small burden for such a large mammal. Sex, age and body condition of the buffaloes had no significant effect on worm occurrence.

    Water buffalo is an indispensable livestock in the Philippines. Leptospirosis is a serious zoonosis that can be fatal to humans and cause reproductive problems in livestock. Leptospirosis has been reported in some countries where water buffaloes are commercially raised, highlighting the Leptospira prevalence in this farming system, but information on leptospirosis in water buffalo farms in the Philippines is limited. In this study, we collected blood samples from rats (n = 21), and water buffaloes (n = 170) from different groups and locations in one intensive-type buffalo farm in the Philippines. Serum was analyzed by microscopic agglutination test (MAT). Anti-Leptospira antibodies reacting with serogroups Canicola, Icterohaemorrhagiae and Pomona were found in sera of 30% tested rats, and 48% of water buffalo sera tested positive for at least one Leptospira strain, in which serogroups Mini, Hebdomadis, Tarassovi and Pyrogenes were predominantly agglutinated. The number of seropositive young water buffaloes (animals were reactive with multiple Leptospira strains with variable MAT titers. In addition, antibodies against serogroups Icterohaemorrhagiae and Pomona were detected in both animals. Finally, Leptospira infection was found associated with age and animal grouping, highlighting the impact of management in the persistence of leptospirosis at intensive-type buffalo farm settings in the Philippines. Further investigation and appropriate control strategies are required to prevent leptospirosis from causing risks to public health and economic losses to the water buffalo farming industry.

    Full Text Available Abstract Background Changes in colostrum composition of Egyptian buffaloes and Holstein cows collected at calving, 6, 12, 24, 48, 72, 96, 120 h and after 14 days of parturition were studied. Total solids, total protein, whey proteins, fat, lactose and ash contents were determined. Macro- and micro-elements, IgG, IgM, IGF-1, lactoferrin and vitamins (A and E were also estimated. Results At calving, the total protein and whey proteins concentration did not differ between buffalo and cow colostrum, while total solids, fat, lactose and ash concentrations were higher in buffalo than in cow colostrum. All components decreased gradually as the transition period advanced except lactose which conversely increased. On the fifth day post-partum, concentration of total protein, whey proteins, fat, ash and total solids decreased by 69.39, 91.53, 36.91, 45.58 and 43.85% for buffalo and by 75.99, 94.12, 53.36, 33.59 and 52.26% for cow colostrum. However, lactose concentration increased by 42.45% for buffalo and 57.39% for cow colostrum. The macro-and micro-elements concentration of both colostrums tended to decline slightly toward normality on the fifth day of parturition. Buffalo colostrum had a higher concentration of vitamin E than cow colostrum during the experimental period. At calving, the concentration of vitamin A in buffalo colostrum was found to be approximately 1.50 times lower than in cow colostrum. The concentrations of IgG, IgM, IGF-1 and lactoferrin decreased by 97.90, 97.50, 96.25 and 96.70% for buffalo and 76.96, 74.92, 76.00 and 77.44% for cow colostrum, respectively after five days of parturition. Conclusions There is a dramatic change in buffalo and cow colostrum composition from the first milking until the fifth day of parturition. There are differences between buffalo and cow colostrum composition during the five days after calving. The composition of both colostrums approaches to those of normal milk within five days after parturition.

    Full Text Available Aim: The present study was designed to: (1 Investigate the effect of weaning time on various metabolic indices and growth pattern in buffalo calves compared to cow calves under field condition and (2 Shed light on the potential relationship between early weaning, growth metabolites, and suboptimal growth (ill-thrift in buffalo calves. Materials and Methods: A total number of 18 neonatal calves of both sexes and species (cattle and buffalo were included in the study. Animals were divided into three groups according to their age at weaning as following: Cow calves (n=8 weaned at 4.5 months, buffalo calves (n=6 weaned at 3.5 months (early-weaned, and buffalo calves (n=4 weaned at 5.5 months (late-weaned. Morphological traits, growth metabolites, and hormonal profile were measured at monthly interval over the period of the study and around the time of weaning (2 weeks pre- and post-weaning. Results: The obtained results showed that the trend of growth pattern was significantly increased in a linear pattern in cow calves and late-weaned buffalo calves, whereas early-weaned buffalo calves showed sharp decline in their body weight (BW post-weaning. By the end of the study, early-weaned buffalo calves showed the lowest BW gain (ill-thrift. There is a positive association between the morphological traits and various growth metabolites and hormonal indices. A significant decrease (p<0.05 in the concentrations of growth hormones (insulin-like growth factor-1 [IGF-1] and insulin and other metabolites were reported in early-weaned buffalo calves compared to other animals. There is no association between stress indices (cortisol level and neutrophil to lymphocyte ratio and growth rate. Conclusion: Suboptimal growth rate (ill-thriftiness is common in early-weaned buffalo calves and is attributed to low blood levels of growth metabolites, in particularly, IGF-1. In addition, the strong positive associations between concentrations of IGF-1 and morphological

    Full Text Available Progeny testing program was started in Nili-Ravi buffalo at Livestock Production and Research Institute (LPRI, Bahadurnagar, Okara in 1979-80. Initially buffalo bulls used at Livestock Experiment Station (LES Qadirabad and Rakh Gulaman during 1964-78 were evaluated. Five out of ten at Rakh Gulaman and 10 out of 22 at Qadirabad bulls were positive. As none of these bulls were available, therefore, sons and grandsons of these bulls were selected for production of future candidate bulls. All the buffaloes at LPRI were evaluat`ed on Most Probable Producing Ability. The elite herd thus formed was used for production for future candidate bulls. Since then a continuous program is in operation at Govt. Livestock Farms and expanded to 27 field sub-centers involving private farmers in four districts Okara, Sahiwal, Faisalabad and Pakpattan. Since the initiation of this program in 1980’s, about 174 bulls have been put under progeny testing program and 137 bulls were evaluated by Daughter-Dam Comparison, out of which sixty eight buffalo bulls contributed positively in milk production of daughters. It is worth mentioning here that milk production of registered buffalo was recorded on monthly intervals in the field along with other necessary reproduction data required to compute the different traits of economic importance.Progeny testing program was started in Nili-Ravi buffalo at Livestock Production and Research Institute (LPRI, Bahadurnagar, Okara in 1979-80.

    Enzootic bovine leucosis is an infectious disease caused by Bovine leukemia virus (BLV) and is well described in bovines. The majority of infected animals are asymptomatic, one to five percent develop lymphoma and from 30 to 50% present a persistent lymphocytosis. The virus occurs naturally in cattle and experimentally in buffaloes, capybaras and rabbits. The occurrence of lymphoma in buffaloes has been attributed to BLV infection by some authors in India and Venezuela, but not confirmed by other studies and little information on natural BLV infection in buffaloes is available. The aim of this study was to evaluate the occurrence of BLV in a sub-sample of buffalo from Amazon and southeast regions in Brazil. Three hundred and fifteen serum samples were negative using commercial AGID and ELISA (ELISA-gp51) which detect anti-BLV glycoprotein gp51 antibodies. The same samples were also evaluated for antibodies to whole virus through a commercial ELISA (ELISA-BLV) in which 77 (24.44%) were found seropositive and two (0.63%) inconclusive. On the other hand, all animals were negative by PCR to BLV targeted to the env and tax genes. These results suggest that ELISA-BLV produces false positive results in buffalo serum (pAmazon basin and the southeast region of Brazil. Serological tests, like ELISA-BLV, usually used for cattle may produce false-positive results for BLV in buffaloes and direct detection tests such as PCR should be chosen in these surveys. The occurrence of lymphoma in buffalo was not associated with BLV infection in the one case analyzed in this work and the etiology and pathogenesis of this disease should be clarified.

    Characterization of field isolates of viruses associated with pox-like outbreaks involving both cows (cattle) and buffaloes was carried out. PCR and electron microcopy of representative virus isolates from these animals, initially identified them as orthopoxviruses (OPXVs). Sequence and phylogenetic analyses of A-type inclusion and haemagglutinin (HA) genes of these isolates revealed a closer relationship with other OPXVs. Sequencing of the HA gene of these isolates revealed sequence identity of 96.2-99.8 and 94.6-98.7% at the nucleotide and deduced amino acid level, respectively, with VACVs, particularly with VACV-MVA, a vaccine strain. Further, C18L (ankyrin repeat protein)-gene-based BPXV-specific PCR confirmed them as BPXV. It is apparent from this study that pox-like outbreaks in cows and buffaloes in India are caused, in most cases, by BPXV. Considering the zoonotic implications of buffalopox, such outbreaks involving both buffaloes and cows in a mixed flock may pose a significant public health threat. Transmissibility of BPXV between different species including cows, buffaloes and human beings implies the potential reemergence of the virus in the subcontinent, similar to vaccinia-like outbreaks witnessed recently in other countries.

    Anaplasma marginale is the most prevalent pathogen of cattle in tropical and subtropical regions of the world and causes the disease bovine anaplasmosis. The importance of water buffalo in the world economy is increasing. In addition, while water buffalo may serve as a reservoir host for A. marginale, the susceptibility of this host for A. marginale cattle strains in Brazil has not been reported. The major surface protein 1 alpha (msp1α) gene has been shown to be a stable genetic marker for identification of A. marginale strains. Herein, we analyzed blood samples from 200 water buffalo and identified the A. marginale strains in an endemic area of Rio de Janeiro, Brazil, where ticks were present and water buffalo and cattle co-mingled. Ticks that were feeding on the study buffalo were collected and identified. The prevalence of A. marginale in water buffalo in this study was low (10%). Sequence analysis of the msp1α gene demonstrated the presence of 8 different A. marginale strains. Two A. marginale strains in the water buffalo, (α-β-β-β-Γ) and (α-β-β-Γ), were similar to those reported in cattle from nearby regions. The results of this study suggested that water buffalo in this region are naturally infected with the same strains of A. marginale found in cattle.

    Full Text Available Since the Thai economy experiences rapid growth, agricultural systems, i.e. crop-livestock systems, are changing rapidly. On account of these changes, buffalo and cattle production has to be re-examined in terms of performance characteristics and roles of livestock for farm households in order to initiate suitable development programmes. Therefore, this study aimed to investigate the present characteristics of beef buffalo and beef cattle farms in Northeast Thailand. Using a semi-structured questionnaire, 121 randomly selected beef buffalo and beef cattle farms were interviewed in Nakhon Ratchasima province between October 2007 and May 2008. Both buffaloes and cattle were mostly integrated in mixed crop-livestock systems with medium to large farm sizes (7.9 ha, whereof less than half of the area was used for livestock. Family members were mainly responsible for the different activities of livestock farming and salaried labourers were only found on large-scale farms. The dominant roles of livestock were income generation to build up wealth or savings, the coverage of expected and unexpected expenses and earning of regular and additional income. Another important issue was the improvement of the social status, which increased with herd size. In order to improve farmers’ livelihoods and develop sustainable farming systems in Northeast Thailand the changing economic circumstances of cattle and especially buffalo production should receive more attention of researchers, governmental institutions and stakeholders.

    Eco-tourism depending on wildlife is becoming increasingly profitable and landowners are beginning to favor game farming and ecotourism. In these areas, large-scale translocation of wildlife involves a diversity of species and large populations. The African buffalo (Syncerus caffer) is one of the major tourist attractions in Zambia. It accounts for 8.7% and 12.4% of the total animal species hunted in the Game Management Areas and the total hunting revenue earned in Zambia, respectively. It is ecologically an important animal species essential for the purpose of habitat control and facilitating the provision of suitable grazing pastures. However, the rearing of the African buffalo on game ranches has been hampered by its carrier state of the Southern Africa Terroritory (SAT) serotypes of foot and mouth disease virus (FMD). The African buffalo is also known to be a carrier of Theileria parva lawrencei, the causative agent of corridor disease (CD) that continues to have devastating effects on the livestock industry in Zambia. In addition, the importation of buffaloes from countries with populations endemic to bovine tuberculosis is highly restricted. Veterinary regulations in Zambia, strongly advocate against the translocation of buffaloes from protected areas to private ranches for disease control purposes thereby mounting a considerable constraint on the economic and ecological viability of the industry. It is hoped that this review will motivate the relevant government authorities in exploiting ways in which this animal species play a central role in eco-tourism.

    The African buffalo (Syncerus caffer) is a large wild bovid which until recently ranged across all but the driest parts of sub-Saharan Africa, and their local range being limited to about 20 km from surface water. They are of high ecological value due to their important role as bulk feeders in the grazing hierarchy. They also have high economic value, because they are one of the sought after 'Big Five' in the eco-tourism industry. In Africa, buffaloes have been recognised for some time as an important role player in the maintenance and transmission of a variety of economically important livestock diseases at the wildlife and/or livestock interface. These include African strains of foot-and-mouth disease (FMD), Corridor disease (theileriosis), bovine tuberculosis and bovine brucellosis. For a number of other diseases of veterinary importance, African buffaloes may also serve as amplifier or incidental host, whereby infection with the causative pathogens may cause severe clinical signs such as death or abortion as in the case of anthrax and Rift Valley fever, or remain mild or subclinical for example heartwater. The long term health implications of most of those infections on the buffalo at a population level is usually limited, and they do not pose a threat on the population's survival. Because of their ability to harbour and transmit important diseases to livestock, their sustainable future in ecotourism, trade and transfrontier conservation projects become complex and costly and reliable diagnostic tools are required to monitor these infections in buffalo populations.

    Full Text Available The present study was conducted to investigate the prevalence of various reproductive disorders and to estimate the economic losses due to genital prolapse in buffaloes in Sir Shamir area of District Faisalabad, Pakistan. The survey was conducted in 8 villages during the 12 months period from June 2005 to May 2006 and the data from 400 farmers (50 farmers from each village were collected. The total buffalo population of this area was 7,785, out of which 2,135 (27.42% animals were included in the study. The overall prevalence of reproductive disorders in buffaloes was recorded as 46.18%. Among all the reproductive disorders, repeat breeding showed the highest prevalence (15.69%, followed by anestrous (9.74%, genital prolapse (7.73%, abortion (5.99%, retained placenta (2.58%, uterine torsion (2.39% and dystocia (2.06%. The total economic losses due to genital prolapse in buffaloes in eight villages during the period of study were estimated to be Rs. 4,59,500/- Among these, the highest losses were due to mortality of dam (39.17%, followed by milk losses (25.14%, service charges (21.33% and medicine cost (14.36%. Thus, repeat breeding, anoestrus and genital prolapse seem to be the major reproductive problems in buffaloes in the study area.

    Full Text Available Aim: To identify the prevalence of Hydatidosis in buffaloe-calves, heifers and adults slaughtered in slaughter house of Mirha Exports Pvt. Ltd. between March 2010 to Feb. 2011.Materials and Methods: 2,09,615 buffaloes slaughtered were included in this study and were categorized into three groups (A, B and C based on their age at the time of ante-mortem examination. Group Aconsisted of calves (>1 year, accounting for 5100 out of the total number of animals. Group B consisted of heifers (2-3 years accounting for 7840. Group C consisted of adult buffaloes (3-7 years accounting for 1, 96675. Results:Our study revealed an overall prevalence of hydatidosis as 50.96%. Furthermore, the group wise analysis showed the prevalence as 3.52%, 5.58% and 54% in calves, heifers and adult buffaloes, respectively.Conclusion: Based on the factors considered, we conclude that the higher prevalence of infections in buffaloes slaughtered in the Mirha Exports is likely due to an overpopulation of stray dogs in the areas from which the plant gets its supply of animals.

    2016-01-01

    Full Text Available This paper proposes the African Buffalo Optimization (ABO which is a new metaheuristic algorithm that is derived from careful observation of the African buffalos, a species of wild cows, in the African forests and savannahs. This animal displays uncommon intelligence, strategic organizational skills, and exceptional navigational ingenuity in its traversal of the African landscape in search for food. The African Buffalo Optimization builds a mathematical model from the behavior of this animal and uses the model to solve 33 benchmark symmetric Traveling Salesman’s Problem and six difficult asymmetric instances from the TSPLIB. This study shows that buffalos are able to ensure excellent exploration and exploitation of the search space through regular communication, cooperation, and good memory of its previous personal exploits as well as tapping from the herd’s collective exploits. The results obtained by using the ABO to solve these TSP cases were benchmarked against the results obtained by using other popular algorithms. The results obtained using the African Buffalo Optimization algorithm are very competitive.

    Full Text Available The objective of this article is to present the possibilities of the economic exploitation of the buffalo population in Greece through the production of certified quality products. The buffalo population in Greece has decreased dramatically during the last decades, due to the rapidly changing socio-economic conditions, mainly the mechanisation of the agricultural sector. The current study has been undertaken in the region of Kerkini Lake, where the majority of buffalo population of Greece is concentrated. The main characteristics of the production system; feeding based on the natural vegetation, the unique way of product processing and the gastronomy are investigated by filling up questionnaires. The next step includes the detailed description of the production system and the definition of the critical points where the intervention will take place. The proper application of the production protocols will be undertaken by the official organisation for certification. The farmers association will be responsible for the management of the transition of the production system. As the driving force of the new development of buffalo breeding is the production of quality products, further investigation on the special characteristics of milk and meat buffalo products, is required.

    Full Text Available Although the largest buffalo herd in the occident is in the north region of Brazil, few studies have been conducted to assess the prevalence of selected parasitic diseases in buffalo herd. The present study was therefore conducted to investigate the epidemiological of Toxoplasma gondii, Neospora caninum, Anaplasma marginale, Babesia bigemina, and Babesia bovis in water buffaloes in the north region of Brazil. A total of 4796 buffalo blood samples were randomly collected from five provinces and simultaneously analyzed by the IFAT and ELISA. The serological prevalence of T. gondii and N. caninum was 41.3% and 55.5% in ELISA and 35.7% and 48.8% in IFAT, respectively. The overall prevalence of A. marginale, B. bovis, and B. bigemina was 63%, 25%, and 21% by ELISA and 50.0%, 22.5%, and 18.8% by IFAT, respectively. This study shows valuable information regarding the serological survey of selected bovine pathogens in water buffaloes in the north region of Brazil which will likely be very beneficial for the management and control programs of this disease.

    To aid in unraveling diverse genetic and biological unknowns, a proteomic approach was used to analyze the whey proteome in cow, yak, buffalo, goat, and camel milk based on the isobaric tag for relative and absolute quantification (iTRAQ) techniques. This analysis is the first to produce proteomic data for the milk from the above-mentioned animal species: 211 proteins have been identified and 113 proteins have been categorized according to molecular function, cellular components, and biological processes based on gene ontology annotation. The results of principal component analysis showed significant differences in proteomic patterns among goat, camel, cow, buffalo, and yak milk. Furthermore, 177 differentially expressed proteins were submitted to advanced hierarchical clustering. The resulting clustering pattern included three major sample clusters: (1) cow, buffalo, and yak milk; (2) goat, cow, buffalo, and yak milk; and (3) camel milk. Certain proteins were chosen as characterization traits for a given species: whey acidic protein and quinone oxidoreductase for camel milk, biglycan for goat milk, uncharacterized protein (Accession Number: F1MK50 ) for yak milk, clusterin for buffalo milk, and primary amine oxidase for cow milk. These results help reveal the quantitative milk whey proteome pattern for analyzed species. This provides information for evaluating adulteration of specific specie milk and may provide potential directions for application of specific milk protein production based on physiological differences among animal species.

    Full Text Available Several ixodid tick species are shared between domestic cattle and African buffaloes (Syncerus caffer. So too, are a number of tick-borne diseases. The aim of the study was to compare the species composition of ticks that infest cattle and buffaloes utilising the same habitat within the Tsavo Conservation Area, Kenya. To this end, 25 cattle and 62 buffaloes were each opportunistically sampled for ticks on a single occasion in February 2010. Eight species, namely Amblyomma gemma, Amblyomma lepidum, Hyalomma albiparmatum, Hyalomma rufipes, Hyalomma truncatum, Rhipicephalus evertsi evertsi, Rhipicephalus pravus and Rhipicephalus pulchellus infested both cattle and buffaloes. Three species, Rhipicephalus (Boophilus sp., Rhipicephalus kochi, and Rhipicephalus muehlensi were collected only from cattle, and three species, Hyalomma impeltatum, Rhipicephalus humeralis and Rhipicephalus praetextatus were present only on buffaloes. The attachment sites of the various tick species were also recorded. New locality records for H. impeltatum and H. truncatum and the first confirmed locality record for Rhipicephalus praetextatus sensu stricto in Kenya were documented.

    Full Text Available The buffalo is a native animal of Iran and there were 500,000 buffaloes in Iran that over 80 per cent of its population concentrated in the north and north- west (Azerbaijan province and 18 per cent in the south (Khuzestan province of the country. Buffaloes reread in rural condition as multi purpose animals in Khuzestan. For mating, farmer use owns herd sire also artificial insemination is limited in the rural condition that may be inbred animals so affect the production performance. The aim of this investigation was estimate the inbreeding coefficient and its affect on some production performance. Data of 200 herds were used from the record sheets of herds under recording program of Animal Breeding Center during period 1990 to 2002 in the Khuzestan province. These results showed mostly herds only one sir and rarely two sires have been used. Inbreeding coefficient was 25 percent in some progeny and high-inbred buffaloes had a low performance. According to results of this study it could be concluded that farmers to avoid inbreeding should use other herd sire and artificial insemination also practical recording scheme and genetically selection to genetic improvement should be included in buffaloes of Iran.

    Cathelicidins are an ancient class of antimicrobial peptides (AMPs) with broad spectrum bactericidal activities. In this study, we investigated the diversity and biological activity of cathelicidins of buffalo, a species known for its disease resistance. A series of new homologs of cathelicidin4 (CATHL4), which were structurally diverse in their antimicrobial domain, was identified in buffalo. AMPs of newly identified buffalo CATHL4s (buCATHL4s) displayed potent antimicrobial activity against selected Gram positive (G+) and Gram negative (G-) bacteria. These peptides were prompt to disrupt the membrane integrity of bacteria and induced specific changes such as blebing, budding, and pore like structure formation on bacterial membrane. The peptides assumed different secondary structure conformations in aqueous and membrane-mimicking environments. Simulation studies suggested that the amphipathic design of buCATHL4 was crucial for water permeation following membrane disruption. A great diversity, broad-spectrum antimicrobial action, and ability to induce an inflammatory response indicated the pleiotropic role of cathelicidins in innate immunity of buffalo. This study suggests short buffalo cathelicidin peptides with potent bactericidal properties and low cytotoxicity have potential translational applications for the development of novel antibiotics and antimicrobial peptidomimetics.

In this study, we investigated the diversity and biological activity of cathelicidins of buffalo, a species known for its disease resistance. A series of new homologs of cathelicidin4 (CATHL4, which were structurally diverse in their antimicrobial domain, was identified in buffalo. AMPs of newly identified buffalo CATHL4s (buCATHL4s displayed potent antimicrobial activity against selected Gram positive (G+ and Gram negative (G- bacteria. These peptides were prompt to disrupt the membrane integrity of bacteria and induced specific changes such as blebing, budding, and pore like structure formation on bacterial membrane. The peptides assumed different secondary structure conformations in aqueous and membrane-mimicking environments. Simulation studies suggested that the amphipathic design of buCATHL4 was crucial for water permeation following membrane disruption. A great diversity, broad-spectrum antimicrobial action, and ability to induce an inflammatory response indicated the pleiotropic role of cathelicidins in innate immunity of buffalo. This study suggests short buffalo cathelicidin peptides with potent bactericidal properties and low cytotoxicity have potential translational applications for the development of novel antibiotics and antimicrobial peptidomimetics.

    Full Text Available Diacylglycerol O-acyltransferase 1 (DGAT1 is a microsomal enzyme that catalyzes the final step of triglyceride synthesis. The DGAT1 gene is a strong functional candidate for determining milk fat content in cattle. In this work, we used PCR-SSCP (polymerase chain reaction-single-strand conformation polymorphism and DNA sequencing to examine polymorphism in the region spanning exon 7 to exon 9 of the DGAT1 gene in Murrah and Pandharpuri buffaloes. Three alleles (A, B and C and four novel single-nucleotide polymorphisms were identified in the buffalo DGAT1 gene. The frequencies of the alleles differed between the two buffalo breeds, with allele C being present in Murrah but not in Pandharpuri buffalo. The allele variation detected in this work may influence DGAT1 expression and function. The results described here could be useful in examining the association between the DGAT1 gene and milk traits in buffalo.

    Replacement of beef by buffalo and vice versa is frequent in global markets, but their authentication is challenging in processed foods due to the fragmentation of most biomarkers including DNA. The shortening of target sequences through use of two target sites might ameliorate assay reliability because it is highly unlikely that both targets will be lost during food processing. For the first time, we report a tetraplex polymerase chain reaction (PCR) assay targeting two different DNA regions in beef (106 and 120-bp) and buffalo (90 and 138-bp) mitochondrial genes to discriminate beef and buffalo in processed foods. All targets were stable under boiling, autoclaving and microwave cooking conditions. A survey in Malaysian markets revealed 71% beef curries contained buffalo but there was no buffalo in beef burgers. The assay detected down to 0.01ng DNA and 1% meat in admixed and burger products.

    Full Text Available Dag defect sperms have an abnormal tail coiled morphology are totally or almost totally immotile and have severe abnormalities on the fibers in the axial filament. This defect in bovine was shown to be due an autosomal recessive gene. In the present study 23 buffalo bulls age 18-34 months examined for BSE (Breeding Soundness Examination showed sperm motility varied between 0 to 70% accomplished with 10 a 65% of sperm pathology with or not a predominance of strong coiled tails with or without persistence of droplet. In Brazil Murrah breed have had only eight female PO (pure of origin - India gave origin of the herd and not more than four males where also imported from India, although in the last two decades some quantity of frozen semen were introduced in the country imported from India. As in the other domestic species inbreed seems to be the main cause of this abnormalities in different breeds. The knowledge and further study of such abnormalities is the only way to overcome a problem that if not controlled will tend to spread out without control causing in the future more problem for development of some herds.

    Full Text Available The aim of this study was to evaluate the coefficients of correlation between curd chemical composition and milk characteristics, theoretical and real cheese yield and ratios between cheese yield and protein percentage. The analysis were performed on 326 milk samples collected from 60 half sib buffaloes, ascertained by DNA test, every 50 days. The percentages of dry matter, proteins and fat of the curd were inversely correlated to the curd firmness (a30, a low enzymatic phase of coagulation and low pH value. Percentage of dry matter in the curd was positively correlated with proteins, casein and fat of the milk and negatively with lactose. Furthermore, dry matter and proteins percentages are also positively correlated with theoretical cheese yield and its ratio with real cheese yield, curd dry matter from 1 litre of milk and the ratio between curd dry matter and protein percentage. Negative correlations were found with real cheese yield at 28 hours (r = - 0.100; P< 0.01 and its ratio with protein percentage. An inverse relationship was highlighted between curd proteins percentage and fat of either milk and curd, while a direct association was present with lactose. A higher protein percentage in the curd was linked to a lower cheese yield and a lower ratio between cheese yield and proteins. Ash of the curd, finally, showed similar association to those described for proteins.

    Full Text Available To improve the efficiency and efficacy of cryopreservation of ovaries, we developed a new method termed in situ oocyte (ISO cryopreservation. ISO cryopreservation is a multistep procedure that involves aspiration of follicular fluid and then perfusion of antral follicles and diffusion of whole buffalo ovaries with cryoprotectant agent (CPA, rapid cooling, storage, thawing and, finally, dilution and removal of the CPA with return to physiological environment. Our study compared ISO cryo ovaries with cryo-diffused ovaries. We systematically examined the effects of ISO cryo and diffuse cryo on ovaries by morphological examination and with viability tests. The percentages of morphologically normal and viable follicular oocytes from ISO cryo were significantly higher than those that resulted from the cryo-diffused method (p<0.01. The quality of follicular oocytes from ISO cryo ovaries appeared better than that achieved from cryo-diffused ovaries. In conclusion, this study shows that ISO cryo is highly efficient for cryopreservation of oocytes and ovarian tissue.

    Full Text Available Assessment of kinetic of AD (Anaerobic Digestion is a beneficial practice to forecast the performance of the process. It is helpful in the design of AD vessels, substrate feeding and digestate exit systems. The aim of this work was to assess the kinetics of anaerobically digested buffalo dung at different quantities of water added. It comprises the assessment of the specific methane production on the basis of VS (Volatile Solids added in each reactor by using three first order models, i.e. the modified Gompertz model, the Cone model and the Exponential Curve Factor model. The analysis was tested by using the three statistical parameters, i.e. the coefficient of multiple determinations, the standard deviation of residuals and the Akaike?s Information Criteria. The result reveals that the Exponential Curve Factor model was the best model that described the experimental data well. Moreover, there was not a direct or indirect relation between the kinetic coefficients of the AD process with the varying total or volatile solid content

    Objective: To determine the possibilities for induction of ovarian activity in Bulgarian Murrah buffaloes by hormonal treatment in the early postpartum period. Methods: Twenty six clinically healthy animals, weighing 480-520 kg, 3-5 years of age, with normal parturition, without clinical signs of endometritis during the entire experimental period were divided into 2 groups: control (n=10) and experimental (n=16). Primiparous and multiparous buffaloes were proportionally allotted into both groups. By 5, 21, and 28 postpartum days, control animals were intramuscularly treated with 2 mL physiological saline, whereas experimental buffaloes received 500 mg PGF2αby the 5th postpartum day, 100 μg GnRH by the 21st postpartum day and a second prostaglandin dose 7 days later. All buffaloes were submitted to transrectal ultrasound examination on days 5, 21 and 28 after calving. Evaluation of ovarian activity was made on the basis of follicle type and detection of a newly formed corpus luteum. The percentage of animals with small, medium or dominant follicle and corpus luteum after either spontaneous or induced ovulation was determined. Insemination management included introduction of two proven fertile bulls into the herd at the start of the treatment. Pregnancy ultrasound checks were performed on postpartum days 58, 68, 120 and 150. The proportion of buffaloes with clinical signs of spontaneous or induced oestrus until the 35th postpartum day, pregnancy rates by the 35th and 90th postpartum days and service periods 90 days were registered. Results: On the 5th day after calving, small follicles were predominating in the ovaries of buffaloes from both groups. Similar findings were established on the 21st day in the control group, whereas the share of experimental buffaloes with small follicles was significantly (P<0.01) lower. By the 21st day, there were no medium follicles in untreated animals, while in hormonally treated ones they were found out in 25% of cases. The

    Improving the quality of in vitro maturated buffalo oocytes is essential for embryo production. We report here the effects on microtubules and microfilaments in oocytes and embryo development that result from treating buffalo oocytes with the phosphodiesterase 3 (PDE3) inhibitor cilostamide. Addition of 20μM or 50μM cilostamide for 24h during in vitro maturation showed no differences in the percentage of oocytes arrested at the germinal vesicle (GV) stage. When 20μM cilostamide was added to the pre-maturation culture for 6h, 12h or 24h and continued for another 24h without cilostamide, oocytes resumed meiosis, but with significantly lower (P0.05). In summary, cilostamide reversibly arrested the resumption of meiosis without any adverse impact on the dynamic changes in microtubules and microfilaments in buffalo oocytes and their in vitro developmental capacity.

    Full Text Available Kundhi is amongst the best dairy buffalo breeds of the world and main source of milk production in Sindh province of Pakistan. A Research and Development Kundhi Buffalo Farm was established at Rohri, Sukkur. Time series production performance data of 237 buffaloes, along with their pedigree, from 1976 through 2004 was collected and analyzed using Harvey Model-1 for fixed effects and DFREML for GLS solutions and genetic / phenotypic variances. The traits of economic importance studied were age at first calving (AFC, milk yield (MY, lactation length (LL, calving interval (CI and dry period (DP. The fixed effects included year of birth (YOB, year of calving (YOC season of calving (SOC and lactation number (L No.. The data analyses revealed that among the fixed effect only YOC had significant effect (p < 0.05 on milk yield and all other traits. The average MY was 1356.48 ± 453.27 kg with mean lactation length 218.72 ± 122.97 days. The heritability of MY, CI, LL and DP was 0.209, 0.018, 0.009 and 0.024, respectively. Among the 5 sires used during this period, one sire contributed positively to milk production of the daughters. One hundred and three Kundhi buffaloes had positive and 134 negative breeding values for milk production. The genetic and phenotypic variance for milk yield was 35427.67 and 168521.94, respectively. The progeny testing program for Kundhi buffalos was initiated in August 2005. Under this program, more than 700 buffaloes are registered and ear tagged. The production and reproduction performance data recording at farmers doorstep has been initiated which will be used to identify bull mothers.

    Bovine tuberculosis (BTB) and brucellosis are prevalent in buffaloes of the Kruger National Park (KNP, South Africa). Both diseases were considered to have no or a very low prevalence in wildlife and livestock in and around the Limpopo National Park (LNP, Mozambique). The same applies for tuberculosis in Gonarezhou National Park (GNP, Zimbabwe), but just recently, BTB was detected in buffaloes in the GNP and fears arose that the disease might also spread to the LNP as a result of the partial removal of the fences between the three parks to form the Great Limpopo Transfrontier Park. To assess the status of both diseases in and around LNP, 62 buffaloes were tested for bovine tuberculosis (BTB) and bovine brucellosis. The percentage of positive BTB reactors in buffalo was 8.06% using BovidTB Stat-Pak® and 0% with BOVIGAM® IFN-γ test and IDEXX ELISA. The brucellosis seroprevalence in buffalo was found to be 17.72% and 27.42% using Rose Bengal Test (RBT) and ELISA, respectively. In addition, 2445 cattle in and around the LNP were examined for BTB using the single intradermal cervical comparative tuberculin test (SICCT), and an apparent prevalence of 0.98% was found with no significant difference inside (0.5%) and outside (1.3%) the park. This is the first published report on the presence of positive reactors to BTB and bovine brucellosis in buffalo and cattle in and outside the LNP. Monitoring the wildlife-livestock-human interface of zoonotic high-impact diseases such as BTB and brucellosis is of outmost importance for the successful implementation and management of any transfrontier park that aims to improve the livelihoods of the local communities.

    Full Text Available The aim of the present study was to evaluate the diagnostic value of Acute Phase Proteins (APP, lipid profiles and proinflammatory cytokines in healthy and bronchopneumonic water buffalo calves. Therefore, sixty water buffalo calves (9±1 month old, 175±15 kg were divided into two equal groups, the first group represented healthy, control, calves whereas calves of the second group were affected with bronchopneumonia. Total leukocytic and differential counts were determined. Serum total protein, albumin, Triacylglyceol (TAG, low density lipoprotein cholesterol (LDL-c, High Density Lipoprotein cholesterol (HDL-c, Total cholesterol, Alanine Amino Transferase (ALT, Aspartate Amino Transferase (AST, Alkaline Phosphatase (ALP, Fibrinogen (Fb, Haptaglobin (Hp, Serum Amyloid A (SAA, Tumor Necrosis Factor-alpha (TNF-α, Interleukins (IL1β, IL-12 and Interferon-gamma (IFN-γ were also determined. In addition, Bronchoalveolar Lavage (BAL was collected and analyzed. The present findings indicated that, total leukocytic and neutrophils counts were significantly (p<0.05 higher in pneumonic water buffalo calves compare with control. The examined biochemical parameters were significantly (p<0.05 increased in pneumonic calves except for total protein, albumin, cholesterol and HDL-c which were significantly (p<0.05 lower compare with control. Serum concentrations of investigated APP and proinflammatory cytokines were significantly (p<0.05 higher in pneumonic water buffalo calves than those of control. The present study demonstrated that, APP, lipid profile and proinflammatory cytokines perhaps served as biomarkers of bronchopneumonia in water buffalo calves. However, future studies with higher baseline sampling are still needed to establish and validate reference values for APP and cytokines in water buffalo calves.

    Milk yield and quality has been a major selection criterion for genetic improvement in livestock species. Role of Prolactin gene in determining milk quality in terms of protein profile, lactose, lipids and other imperative macromolecules is very important. In this context, genetic profiling of Prolactin gene in riverine buffalo of Pakistan was performed and potential genetic markers were identified illustrating worth of this gene in marker-assisted selection of superior dairy buffaloes. Series of wet and dry lab experimentation was performed starting with genomic DNA isolation from true to breed representatives of indigenous river buffalo (Nili-Ravi). After amplification of coding regions of Prolactin gene, products were eluted and sequenced by Sanger's chain termination method and aligned to get variations in genomic region. A total of 15 novel variations were identified and analyzed statistically for their significance at population level, haplotypes were constructed, and association was estimated. Phylogenetic analysis was performed to evaluate the rate of evolution for Prolactin gene in various mammalian species. Lastly, biological networking for this molecule was predicted to get the bigger pictorial of its functional machinery. Pathway analysis was performed to find its physiological mode of action in milk synthesis. This is a first report toward complete genetic screening of Prolactin gene in Pakistani buffaloes. Results of this study not only provide an insight for potential role of Prolactin gene in milk-producing abilities of buffalo but also suggest new directions for exploration of more genes that may have promising role to enhance future milk production capabilities of river buffalo breeds of Asian region through marker-assisted selection.

For this study eight first ejaculates, four each from a buffalo and a cow (Sahiwal bull were used. The ejaculates were split-sampled and diluted with Tris-citric acid extender (at 37°C; 50x 106 spermatozoa/mI, containing either SP (streptomycin 1000 ~g/ml and penicillin 1000 IU/ml or GTLS (gentamycin 500 µg/ml, Tylosin 100 µg/ml and linco-spectin 300/600 µg/ml. There was no difference in post-thaw motility for these samples. Fertility test based on 75-days first service pregnancy rate was determined under field conditions. A total of 400 inseminations were recorded, 200 for each buffalo and cow (Sahiwal with J 00 of each antibiotic combination, respectively. Fertility rates for SP-based frozen semen of buffalo bull were 41.66% and were 55.2% for GTLS-containing frozen semen, respectively. The results for GTLS were higher (P<0.0001 than SP. Similarly, fertility rates were higher (P<0.0001 for GTLS-based frozen semen of Sahiwal bull (78.78% than SP-containing frozen semen (69.6% of the same specie. Fertility rates also differed due to species of donor bulls. They were better (P<0.0001 for the frozen Sahiwal bull semen than that of the buffalo bull in both SP and GTLS- based frozen semen samples, respectively. In conclusion. seminal quality measured by field fertility trial indicated GTLS combination of antibiotics added to the semen extender was better for improvement in the fertility of frozen buffalo and Sahiwal bull semen, by yielding better pregnancy rates through AI.

    Full Text Available Abstract Background The recently constructed river buffalo whole-genome radiation hybrid panel (BBURH5000 has already been used to generate preliminary radiation hybrid (RH maps for several chromosomes, and buffalo-bovine comparative chromosome maps have been constructed. Here, we present the first-generation whole genome RH map (WG-RH of the river buffalo generated from cattle-derived markers. The RH maps aligned to bovine genome sequence assembly Btau_4.0, providing valuable comparative mapping information for both species. Results A total of 3990 markers were typed on the BBURH5000 panel, of which 3072 were cattle derived SNPs. The remaining 918 were classified as cattle sequence tagged site (STS, including coding genes, ESTs, and microsatellites. Average retention frequency per chromosome was 27.3% calculated with 3093 scorable markers distributed in 43 linkage groups covering all autosomes (24 and the X chromosomes at a LOD ≥ 8. The estimated total length of the WG-RH map is 36,933 cR5000. Fewer than 15% of the markers (472 could not be placed within any linkage group at a LOD score ≥ 8. Linkage group order for each chromosome was determined by incorporation of markers previously assigned by FISH and by alignment with the bovine genome sequence assembly (Btau_4.0. Conclusion We obtained radiation hybrid chromosome maps for the entire river buffalo genome based on cattle-derived markers. The alignments of our RH maps to the current bovine genome sequence assembly (Btau_4.0 indicate regions of possible rearrangements between the chromosomes of both species. The river buffalo represents an important agricultural species whose genetic improvement has lagged behind other species due to limited prior genomic characterization. We present the first-generation RH map which provides a more extensive resource for positional candidate cloning of genes associated with complex traits and also for large-scale physical mapping of the river buffalo

The treatment group was fed with a concentrate supplemented with 30 g of dry powder of L. spinosa/head/d for 7 months. It was found that L .spinosa could have effect on male and female buffalo growth rate. The growth rate of male SS treated group were 130 g/d higher than control group. In female both SS and MS buffalo, the highest growth rate (830 to 840 g/d was found after the 2nd month of treatment while a reduction in growth rate (-1,030 to - 450 g/d was found in the 3rd month. After that the growth rate of SS and MS gradually increased until the last three months to 200 and 80 g/d in average, respectively. In female MS, plasma E2 in the treated group was lower than control group during Jan to Jul. Similar result was found in SS female, level of plasma E2 in treated group was lower than in control group in the first and last three month and there was no difference of plasma E2 in May. In MS male, the level of plasma E2 of treated group was higher than control group in Jan, Mar, Apr and Jul. In SS male, the level of plasma E2 of treated group was higher than control group in every month except in Jul. In female SS, L. spinosa could decreased plasma P4 through the experiment and could not have an effect on plasma P4 in female MS and plasma T in male buffalo calves. In conclusion, the addition to the concentrate of dry powder of L. spinosa 30 g/headl/d had an effect to increase growth rate in male SS and female MS buffalo calves, decrease plasma E2 in female both SS and MS and male SS and decrease plasma P4 in female SS.

Methods:The study was carried out in 46 Bulgarian Murrah buffaloes with small inactive ovaries established by two consecutive transrectal ultrasonographies on Day 40 and 50 postpartum. At the start of the therapy the buffaloes were randomly divided into three groups. Group I (n=18) was treated by PRID-based protocol;Group II (n=18) was treated by Ovsynch based protocol and Group III (control;n=10) was injected intramuscular with saline at the same days as in the first two groups and fertile bull was introduced after that. The animals in the different groups were submitted to ultrasound examination at day of artificial insemination or bull introduction. Ovulation was determined 7 days post insemination by ultrasound. The pregnancy diagnosis was done 30 days after insemination. Mean diameter of the largest follicles at the start of therapy and the day of AI was registered. In the hormonal treated buffaloes estrus clinical sings, ovulation rate and pregnancy rate after AI were determined. In the control group pregnancy rate after spontaneous estrus was established. The mean diameter of the largest follicles determined on Days 40 and 50 after calving was not over 9 mm for all buffaloes. Results:At day of AI the average diameters of the preo-vulatory follicles in PRID and Ovsynch treated buffaloes were significantly (P<0.01) greater than these on Day 0. The cases of a clear uterine mucus discharge during the induced estrus were significant more (P<0.05) for Group I (94.4%) than Group II (66.7%). The pregnancy rate after AI (56.6%and 38.8%) in PRID and Ovsynch program was significant higher (P<0.05) than pregnancy rate after spontaneous estrus (10%) in the control group. Conclusions:the treatment of buffalo ovarian inactivity could start on Day 50

    Full Text Available Seasonal feed resources are of prime importance for swamp buffaloes to support the efficient production under the prevailing small-holder farming systems. Manipulations of rumen microorganisms, fermentation and subsequent absorption by the animals are essential. Current research work on locally available feed resources such as urea-treated rice straw, cassava hay etc. revealed significant improvement in rumen ecology with higher cellulolytic bacteria and fungal zoospores and subsequent fermentation endproducts. However, investigation of rumen microorganisms diversity of swamp buffalo and their roles in fermentation using molecular technique especially the use of PCR – DGGE/ Real Time- PCR warrant future research undertakings.

    Full Text Available Descreve-se um surto de tétano em búfalos da raça Murrah em uma propriedade situada no município de São Caetano de Odivelas, localizado na região metropolitana de Belém, estado do Pará. Do rebanho de 250 bubalinos, 80 animais foram vacinados contra raiva por via intramuscular na região da garupa. Em um período de 15 a 19 dias após a vacinação quatro animais adoeceram, um morreu com dois dias de evolução, um foi eutanasiado in extremis no sétimo dia após o início dos sinais clínicos e os demais se recuperaram após tratamento. Nos bubalinos, o primeiro sinal clínico observado foi o prolapso da terceira pálpebra, em especial quando o animal era estimulado, seguido por andar rígido, manifestado por dificuldade de flexão dos membros e permanência em decúbito lateral com os membros estendidos, pálpebras muito abertas, sialorréia, hiperexcitabilidade, orelhas eretas, leve trismo e acúmulo de alimento na cavidade oral. À necropsia foi evidenciada uma área de coloração amarelada com presença de exsudação purulenta na musculatura da região da garupa, local de aplicação da vacina. Ao exame histopatológico não foram evidenciadas alterações significativas. Em dois animais foi realizado tratamento com penicilina por via intramuscular e soro antitetânico por via intramuscular e sub-aracnóide; após duas semanas esses animais se recuperaram. Diante do quadro clínico, dos dados epidemiológicos e da ausência de lesões histológicas foi feito o diagnóstico de tétano. Concluiu-se que o tétano é uma doença a ser considerada na bubalinocultura no Brasil. A infecção, provavelmente ocorreu durante o procedimento de vacinação, através injeções intramusculares utilizando agulhas contaminadas.An outbreak of tetanus in Murrah buffaloes in Belém, state of Pará, Brazil, is described.

    Full Text Available In this study the trait Stayability (SA was evaluated according to the year of cull after first calvin, i.e., SA 1 to 6 for 1 to 6 years from first calving in lactating females from bubaline milk herds spread in nine farms located in São Paulo state. Informations were used regarding 1027 lactating Murrah breed buffaloes. The statistical analyses were made using LIFEREG (SAS, 1999 procedure. The SA was evaluated using the fixed effects: farm production, birth year, calving season (Season 1- April to September and Season 2 October - March and class of milk yield at 270 days. The age at first calving (AFC was considered as a random effect. The mean observed for total milk yield was 1458.75Kg. Calving Season 2 encloses 65.6% of births. The means of cull age, in months, and the percentage of SA were, respectively: 10.69 e 69% (SA1, 19.30 e 63% (SA2, 26.4 e 54% (SA3, 33.15 e 42% (SA4, 38.53 e 36% (SA5 e 42.65 e 26% (SA6. It is verified that most of culls happens after the first lactation, among the sixth and eleventh month after first calving. It was observed that the factors: farm production, birth year and class of milk yield at 270 days affected significantly all SAs. Factors like calving season and the age at first calving (AFC were only significant for SA1. Being significant the factor AFC in level of 1% and factor time in 10%.

    Full Text Available Cystic echinococcosis (CE, caused by the larval stages of the tapeworm Echinococcus granulosus, is known to be one of the most important parasitic infection in livestock worldwide and one of the most widespread zoonoses known. In the present study, we used a geographical information system (GIS to study the spatial structure of livestock (cattle, water buffaloes and sheep populations to gain a better understanding of the role of sheep as reservoir for the transmission of CE to cattle and water buffaloes. To this end, a survey on CE in cattle and water buffaloes from the Campania region of southern Italy was conducted and the geo-referenced results linked to the regional farm geo-referenced data within a GIS. The results showed a noteworthy prevalence of CE in cattle and water buffalo farms (overall prevalence = 18.6%. The elaboration of the data with a GIS approach showed a close proximity of the bovine and/or water buffalo CE positive farms with the ovine farms present in the study area, thus giving important information on the significance of sheep and free-ranging canids in the transmission cycles of CE in relation to cattle and water buffaloes. The significantly higher prevalence found in cattle as compared to water buffalo farms (20.0% versus 12.4% supports the key role of sheep in the CE transmission; indeed, within the 5 km radius buffer zones constructed around the cattle farms positive for CE, a higher number of (potentially infected sheep farms were found compared to those found within the buffer zones around the water buffalo farms. Furthermore, the average distances between the sheep and cattle farms falling in the same buffer zones were significantly lower than those between the sheep and water buffalo farms. We emphasize that the use of GIS is a novel approach to further our understanding of the epidemiology and control of CE and we encourage other groups to make use of it.

    The favorable cellular response of newly developed cell line, buffalo embryonic stem (ES) cells to three-dimensional biodegradable chitosan-gelatin composite scaffolds with regard to stem-cell-based tissue engineering is described. Chitosan-gelatin composites were characterized by a highly porous structure with interconnected pores, and the mechanical properties were significantly enhanced. Furthermore, X-ray diffraction study indicated increased amorphous content in the scaffold on the addition of gelatin to chitosan. To develop a transfectant of green fluorescence protein (GFP)-buffalo ES cell, transfection of GFP plasmid to the cell was carried out via the electroporation procedure. In comparison with pure chitosan, cell spreading and proliferation were greater in highly visualized GFP-expressing cell-chitosan-gelatin scaffold constructs. The relative comparison of biological response involving cell proliferation and viability on the scaffolds suggests that blending of gelatin in chitosan improved cellular efficiency. Studies involving scanning electron and fluorescence microscopy, histological observations and flow cytometer analysis of the constructs implied that the polygonal cells attached to and penetrated the pores, and proliferated well, while maintaining their pluripotency during the culture period for 28days. Chitosan-gelatin scaffolds were cytocompatible with respect to buffalo ES cells. The study underscores for the first time that chitosan-gelatin scaffolds are promising candidates for ES-cell-based tissue engineering.

    2007-09-01

    Full Text Available Abstract Background African buffaloes are the maintenance host for Mycobacterium bovis in the endemically infected Kruger National Park (KNP. The infection is primarily spread between buffaloes via the respiratory route, but it is not known whether shedding of M. bovis in nasal and oral excretions may lead to contamination of ground and surface water and facilitate the transmission to other animal species. A study to investigate the possibility of water contamination with M. bovis was conducted in association with a BCG vaccination trial in African buffalo. Groups of vaccinated and nonvaccinated buffaloes were kept together with known infected in-contact buffalo cows to allow natural M. bovis transmission under semi-free ranging conditions. In the absence of horizontal transmission vaccinated and control buffaloes were experimentally challenged with M. bovis. Hence, all study buffaloes in the vaccination trial could be considered potential shedders and provided a suitable setting for investigating questions relating to the tenacity of M. bovis shed in water. Results Serial water samples were collected from the drinking troughs of the buffaloes once per season over an eleven-month period and cultured for presence of mycobacteria. All water samples were found to be negative for M. bovis, but 16 non-tuberculous Mycobacterium spp. isolates were cultured. The non-tuberculous Mycobacterium species were further characterised using 5'-16S rDNA PCR-sequencing, resulting in the identification of M. terrae, M. vaccae (or vanbaalenii, M. engbaekii, M. thermoresistibile as well as at least two species which have not yet been classified. Conclusion The absence of detectable levels of Mycobacterium bovis in the trough water suggests that diseased buffalo do not commonly shed the organism in high quantities in nasal and oral discharges. Surface water may therefore not be likely to play an important role in the transmission of bovine tuberculosis from buffalo

    2014-06-17

    Background: Copy number variations (CNVs) are a main source of genomic structural variations underlying animal evolution and production traits. Here, with one pure-blooded Angus bull as reference, we describe a genome-wide analysis of CNVs based on comparative genomic hybridization arrays in 29 Chinese domesticated bulls and examined their effects on gene expression and cattle growth traits.Results: We identified 486 copy number variable regions (CNVRs), covering 2.45% of the bovine genome, in 24 taurine (Bos taurus), together with 161 ones in 2 yaks (Bos grunniens) and 163 ones in 3 buffaloes (Bubalus bubalis). Totally, we discovered 605 integrated CNVRs, with more " loss" events than both " gain" and " both" ones, and clearly clustered them into three cattle groups. Interestingly, we confirmed their uneven distributions across chromosomes, and the differences of mitochondrion DNA copy number (gain: taurine, loss: yak & buffalo). Furthermore, we confirmed approximately 41.8% (253/605) and 70.6% (427/605) CNVRs span cattle genes and quantitative trait loci (QTLs), respectively. Finally, we confirmed 6 CNVRs in 9 chosen ones by using quantitative PCR, and further demonstrated that CNVR22 had significantly negative effects on expression of PLA2G2D gene, and both CNVR22 and CNVR310 were associated with body measurements in Chinese cattle, suggesting their key effects on gene expression and cattle traits.Conclusions: The results advanced our understanding of CNV as an important genomic structural variation in taurine, yak and buffalo. This study provides a highly valuable resource for Chinese cattle\\'s evolution and breeding researches. 2014 Zhang et al.; licensee BioMed Central Ltd.

    Full Text Available The present study was executed to determine the magnitude of bovine tuberculosis (BTB in buffaloes in native type of husbandry practices and impact of certain factors in the prevalence of bovine tuberculosis in buffaloes in the Punjab, Pakistan. Three year cross sectional study was carried out on female population of Nili Ravi buffaloes (n = 2526 maintained at 10 Government Livestock Experimental Stations, and peri urban areas of the three major cites i.e., Lahore, Faisalabad and Okara. These animals were screened with comparative intradermal tuberculin test (CIDT by using two types of tuberculins i.e., mammalian and avian. The reaction of tuberculins injected was interpreted after 72 hours post injection. The data were analyzed by Chi-square test and Pearson correlation. Relative risk and other associated factors were calculated to describe the association with prevalence of tuberculosis in buffaloes. The prevalence of bovine tuberculosis on the basis of CIDT was 12.72%. The BTB among different livestock farms varied significantly (P8 years old age, body weight >550 kg, 3-6 parity, pregnant animals, and animals with >7 liters milk yield. The husbandry factors which greatly influence the prevalence was poor feeding (RR=2.615, high fly density (RR= 1.3474, poor management (RR=1.315, contact with wildlife (RR=1.4507, poor farm conditions (RR=1.4708, quarantine measures (RR=1.1557 and poor sanitation of farm (RR= 1.3701.

    Full Text Available Approximately 1,500 Toda people inhabit the Nilgiri Mountains in south India. Arguably the most remarkable characteristic of Toda culture is the sacred nature of the husbandry of herds of long-horned mountain water buffaloes. No other community in India has so single-mindedly focused its ritual attention on one particular animal species. Every important task associated with the buffalo herds – milking, milk-processing, giving salt, naming, seasonal migrations, burning pastures, introducing new equipment into the dairies, etc. – has been embellished with ritual. Todas make a clear-cut distinction between temple and domestic buffaloes. Ordinary men (but not women herd the latter, whose milk and milk-products (buttermilk, butter, and clarified butter, but not flesh (since the community espouses vegetarianism may be consumed, bartered, or sold without restriction. Males who are responsible for herding temple buffaloes conduct their daily lives in a manner preserving greater ritual purity than ordinary men. Moreover, they are not just dairymen, but also the community's priests. They must guard the ritual purity of the dairies they serve, and all that is in them, for these are the Todas' temples – sacred places, infused with divinity.

    Full Text Available Buffalo husbandry is an important source of income for a number of small-scale producers in Romania that is why an assessment of its products quality is much needed for improvement and evaluation of their vulnerability to international competition. In order to ascertain possible developments in the buffalo dairy sector and to broadly identify areas of intervention that favor small-scale dairy producers, the study examined the potential to improve buffalo milk production by evaluating its authenticity and hygienic quality. The methods used involved the molecular testing (PCR-technique for identifying cow, sheep or goat DNA in the dairy products samples collected from the small-scale producers market. The hygienic quality of these samples was determined through classical microbiology methods, highly developed techniques (Trek System and PCR for bacterial species confirmation. The results showed that a high percent (65%, from the products found were adulterated with other species milk, mostly cow milk. The most commonly falsified buffalo dairy products were the cheese and the traditional product telemea. The prevalence of the bacterial species identified belonged to Listeria innocua and Listeria welshmeri. The conclusion of this study is the need of a durable development system in this particular dairy chain to improve and assure the authenticity and quality of the small-scale producers products and their reliability for the consumers.

    Full Text Available This study was carried out to determine if a new antibiotic combination comprising of gentamycin, tylosin and linco-spectin (GTLS in extender is suitable for improvement in fertility of liquid buffalo bull semen through artificial insemination (AI. Two consecutive ejaculates per week (4 weeks were collected from three Nili-Ravi buffalo bulls of known fertility by using artificial vagina. The pooled ejaculates were split-sampled and diluted with skimmed milk extender (37oC; 10x106 motile spermatozoa/ml containing either SP (streptomycin 1000 μg/ml and penicillin 1000 iu/ml or GTLS (gentamycin 500 μg/ml, tylosin 100 μg/ml, lincomycin 300 μg/ml, and spectinomycin 600 μg/ml. Liquid semen was stored at 5°C for seven days. Fertility, based on 90-days first service pregnancy rate, was determined under field conditions. The fertility rates for SP-based vs. GTLS-containing liquid semen of buffalo bull were 58.55 and 60.00%, respectively, the difference was non significant. The fertility rates also did not differ (P>0.05 due to antibiotics at different days of storage of liquid semen at 5oC. In conclusion, GTLS, in skimmed milk extender compared to SP, did not significantly improve the fertility of chilled buffalo bull semen.

    Full Text Available The extensive use of buffalo in agriculture, especially in developing countries, begs for genetic resources to evaluate and improve traits important to local and regional economies. Brazil presents the largest water buffalo populations in the New World, with 1.1 million heads including swamp and river types. To design rational breeding strategies for optimum utilization and conservation of available genetic variability in the Brazilian buffalo’s population, it is essential to understand their genetic architecture and relationship among various breeds. This depends, in part, on the knowledge of their genetic structure based on molecular markers like microsatellites. In the present study, we developed six enriched partial genomic libraries for river buffalo using selective hybridization methods. Genomic DNA was hybridized with six different arrays of repeat motif, 5’ biotinylated - (CA15, (CT15, (AGG8, (GAAA8, (GATA8, (AAAAC8 – and bound to streptavidin coated beads. The cloning process generated a total of 1920 recombinant clones. Up to date, 487 were directly sequenced for the presence of repeats, from which 13 have been positive for presence of repeats as follows: 9 for di-nucleotide repeats, 3 for tri-nucleotide repeats and 1 for tetra-nucleotide repeat. PCR primer pairs for the isolated microsatellites are under construction to determine optimum annealing temperature. These microsatellites will be useful for studies involving phylogenetic relationships, genome mapping and genetic diversity analysis within buffalo populations worldwide.

The lower ventral area just lateral to linea alba (on both sides of the udder in standing animals was scanned transabdominally by the two-dimensional convex transducer for various ultrasonographic findings. The data collected were statistically analyzed by “one-way ANOVA” and “independent sample t-test” using computerized SPSS 16.0 software program. Results: Transabdominal ultrasonography revealed dead fetus in 95% uterine torsion cases and proved useful in imaging internal structures of fetuses while no dead fetus was reported in the control group. Size of umbilicus was found significantly decreased (p0.05 in uterine torsion group. Average thickness of the uterine wall and mean pixel values of fetal fluids (echogenicity were found significantly increased (p<0.05 in uterine torsion affected buffaloes in comparison to control group. Conclusion: Status of fetus (whether live or dead, internal status of uterus, and its contents could be determined by transabdominal ultrasonography in uterine torsion cases and thus determining the prognosis of the uterine torsion cases before going for further manipulations. This will also help in taking all the precautions to avoid death of the fetus.

    Conclusion: Two different species of bacteria i.e., S. aureus and E. coli are contaminating with milk samples. The pathogenic bacteria can be controlled effectively by using Ciprofloxacin and Levofloxacin in the case of mastitis in cattle and buffaloes in Bangladesh. [J Adv Vet Anim Res 2016; 3(1.000: 62-67

    Full Text Available Integrative management of wildlife and livestock requires a clear understanding of the diseases transmitted between the two populations. The tick-borne protozoan parasite Theileria parva causes two distinct diseases in cattle, East Coast fever and Corridor disease, following infection with parasites derived from cattle or buffalo, respectively. In this study, cattle were immunized with a live sporozoite vaccine containing three T. parva isolates (the Muguga cocktail, which has been used extensively and successfully in the field to protect against cattle-derived T. parva infection. The cattle were exposed in a natural field challenge site containing buffalo but no other cattle. The vaccine had no effect on the survival outcome in vaccinated animals compared to unvaccinated controls: nine out of the 12 cattle in each group succumbed to T. parva infection. The vaccine also had no effect on the clinical course of the disease. A combination of clinical and post mortem observations and laboratory analyses confirmed that the animals died of Corridor disease. The results clearly indicate that the Muguga cocktail vaccine does not provide protection against buffalo-derived T. parva at this site and highlight the need to evaluate the impact of the composition of challenge T. parva populations on vaccine success in areas where buffalo and cattle are present.

    A buffalo oocyte-specific subtracted cDNA library was constructed to identify exclusively or preferentially oocyte-expressed genes. The library represented an enriched population of transcripts obtained from oocytes of diverse ovarian follicular origin and at different stages of in vitro maturation. A total of 1173 high-quality sequences of oocyte-specific genes were clustered into 645 unique sequences, out of which 65.76% were represented as singlets and 34.26% as contig expressed sequence tags (ESTs; clusters). Analysis of sequences revealed that 498 of these sequences were identified as a known sequence in mammalian species including buffalo, 103 as uncharacterized ESTs and 44 unknown sequences including 1 novel EST, so far not reported in any species. Gene ontology annotation classified these sequences into functional categories of cellular events and biological processes associated with oocyte competence. Expression status of the isolated unknown ESTs confirmed that many of these are expressed in oocytes exclusively and in others preferentially, some in excess of 80-fold greater in comparison with a variety of somatic tissues. The isolated novel EST was detected to be expressed exclusively in oocytes and testicular cells only. To our knowledge, this is the first report giving a detailed transcriptome account of oocyte-expressed genes in buffalo. This study will provide important information on the physiological control of oocyte development, as well as many questions yet to be addressed on the reproductive process of buffalo.

    Full Text Available A feeding trial was conducted in graded Murrah buffaloes to study the influence of yeast culture (Saccharomyces cerevisiae CNCM I-1077 strain supplementation on intake and nutrient utilization. 12 graded Murrah buffaloes with an average body weight of 465.4 ± 20.92 kg were randomly divided into two groups (Control and treatment of 6 animals each. Animals in both the groups received a basal diet comprising of roughages and concentrates separately to meet the maintenance and production requirements (ICAR, 1998. In addition, the animals in treatment group received yeast culture @ 0.5 g/animal/day. The average DMI of buffaloes during the digestion trial was 114.31 and 119.24 g/kg W0.75 respectively, in control and treatment groups. The digestibility coefficients of gross nutrients and fibre fractions showed non-significant differences between the control and treatment groups, though the values were found to be comparatively higher in the yeast supplemented group.
