    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. In these countries, buffalo genetic breeding programs have been performed for many decades.

    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.

    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.

    Full Text Available Sixteen 14-month-old swamp buffalo (Bubalus bubalis heifers were used to study the effect of supplementary lighting on eating time, number of meals and meal duration and growth performance. Eightheifers were allocated to a natural photoperiod regime, receiving approximately 12 h of daylight, (control treatment and eight heifers were allocated to a supplementary lighting regime, receiving an additional 6 h of artificial light during the night, (light supplemented treatment using a cross-over design. Rice straw wasoffered ad libitum and commercial concentrate was also offered approximately 1.5 kg/animal/day. Supplementary lighting was provided by eight 60 W white fluorescent tubes placed approximately 2.5 m above theground under the roof. Supplementary lighting did not significantly effect eating behaviour, daily intake or live weight gain. It is concluded that the performance of corralled buffalo heifers cannot be improved by the provision of supplementary lighting.

    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.

    Of 103 water buffalo (Bubalus bubalis) examined on Khong Island by means of the M.I.F.C. and hatching techniques, none were passing eggs resimbling those of the Mekong schistosome. One buffalo calf was infected with Orientobilharzia harinasutai and another with Schistosoma spindale; this is the first time these parasites have been reported from Laos. Since the buffalo that were examined had constant and year-round access to a part of the Mekong River that has been shown to be a site of heavy transmission of schistosomiasis to humans and dogs, it was considered that the buffalo would have acquired the infection with the human Mekong schistosome if this were possible. In the absence of buffalo necropsies, and since no eggs of the Mekong schistosome were detected in the stools of these animals, we assumed that they had either not become infected with this parasite or, if they had, that the infections did not produce eggs in the faeces which were detectable by the methods employed. On the basis of our examinations, it would not seem that domestic water buffalo are involved as reservoirs in the epidemiology of human schistosomiasis on Khong Island.

    Parainfluenza virus type 3 (PIV3) was isolated from dairy buffaloes (Bubalus bubalis) naturally affected with respiratory and reproductive clinical conditions. 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). 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.

    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.

    Swamp buffalo (Bubalus bubalis) is an endemic species and one of the genetic wealth of South Sumatra with a distribution area in the district of Pampangan (OganIlir and OganOganIlir). Suspected inbreeding causes decreased phenotypic properties. Inbreeding among various swamp buffalo is certainly not only lower the qualities but also genotypes and phenotypes. It is of interest to determine kinship variants swamp buffaloes from Pampangan through the analysis of a blood protein profile. Blood protein profile of four variants swamps buffalo was studied by using five electrophoresis system i.e. pre-albumin (Palb), albumin (Alb), ceruloplasmin (Cp), transferrin (Tf) and transferrin post (Ptf). In this paper, it is obtained that there was no significant differences among the four variants of the buffaloes were used as a sample. Prealbumin has two alleles (Palb1 and Palb2), albumin has three alleles (Alba, AlbB, AlbC), ceruloplasmin has one allele (BPA), post-transferrin has one allele (PTFA) with an allele frequency 1.0000 at any time transferrin has two alleles (TFA and TFB) with the allele frequency of 0.7500 and 1.0000. Characteristics prealbumin (Palb), albumin (Alb), ceruloplasmin (Cp), and post-transferrin (P-tf) is monomorphic, while transferrin is polymorphic average heterozygosity values all loci (H) 0.1286. Based on average heterozygosity, the swamp buffalo (Bubalusbubalis) from Pampangan has low genetic variation and closest genetic relationship.

    Full Text Available Abstract Background Indian cattle (Bos indicus and riverine buffalo (Bubalus bubalis give a poor yield of milk but it has a high fat and protein percentage compared to taurine cattle. The identification of QTLs (Quantitative Trait Loci on BTA14 and BTA6 and its subsequent fine mapping has led to identification of two non conservative mutations affecting milk production and composition. Our objective was to estimate the frequency of K232A (DGAT1 – diacylglycerol – acyltransferase 1 and Y581S (ABCG2 – ATP binding cassette sub family G member 2 polymorphisms in diverse cattle and buffalo breeds of India having large variation in terms of milk production. Results We screened the reported missense mutations in six cattle and five buffalo breeds. The DGAT1K and ABCG2Y alleles were found to be fixed in Indian cattle and buffalo breeds studied. Conclusion This study provides an indirect evidence that all the Indian cattle and buffalo breeds have fixed alleles with respect to DGAT1 and ABCG2 genes reported to be responsible for higher milk fat yield, higher fat and protein percent.

    Full Text Available Embryonic mortality is one of the main causes responsible of the decline in fertility that occurs in buffaloes during periods of increasing daylight length (out sexual breeding season. Transrectal ultrasonography for pregnancy diagnosis offers some advantages over palpation per rectum: earlier diagnosis of pregnancy/non-pregnancy, determination of embryo/fetus viability, reduction of misdiagnosis, and reduction of .potential. iatrogenic embryo/fetal attrition. Non pregnant buffaloes on Day 25 after AI showed higher Resistive Index (RI (P<0.05 and Pulsatility Index (P=0.07 values, registered on CL on Days 10 after AI, compared to pregnant buffaloes. RI values were significantly higher (P=0.02 in non pregnant buffaloes also on Day 45 after AI. Colour Doppler sonography could be used to gain specific information relating to the ovarian blood flow in predicting early embryonic loss and to describe the ultrasonographic features of early embryonic death in buffaloes.

    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.

    Water buffaloes (Bubalus bubalis) are quite well adapted to climatic conditions in the Amazon, and in this biome, they are noted for the considerable amount of meat and milk they produce and how hard they are able to work. Because of a lack of research dedicated to improving the rearing of buffaloes in the Amazon, the objective of this study was to genetically characterize the Murrah and Mediterranean breeds, as well as a mixed-breed population, based on polymorphisms in the diacylglycerol O-acyltransferase 1 gene (DGAT1), and associate the genotypes with milk production. By using the polymerase chain reaction-single-strand conformation polymorphism technique, the alleles A (0.79), B (0.20), and D (0.01) were found in the Murrah breed. In the Mediterranean and mixed-breed buffaloes, we found alleles A (0.69) and (0.77) and B (0.31) and (0.23), respectively. The Murrah breed had the genotypes AA (0.63), AB (0.29), BB (0.05), and AD (0.03), and the Mediterranean and mixed-breed buffaloes had the genotypes AA (0.44) and (0.61), AB (0.50) and (0.31), and BB (0.06) and (0.08), respectively. For the Murrah, Mediterranean, and mixed-breed buffaloes, respectively, the expected heterozygosity values were 0.34, 0.43, and 0.35, the inbreeding coefficients were 0.78, -0.15, and 0.17, and the Hardy-Weinberg probabilities were 0.70, 0.67, and 0.52. The genotypes evaluated did not have an effect on milk production; however, the single nucleotide polymorphisms can be used in studies on genetic variability.

    The infection of gastrointestinal helminths in livestock is routinely diagnosed by microscopical examination of faecal samples for the presence of ova/eggs but this approach becomes ineffective for the seasonally egg producing trematodes. Therefore, an alternative approach to detect the coproantigens of liver and rumen amphistomes, Gigantocotyle explanatum and Gastrothylax crumenifer respectively, infecting Indian water buffalo Bubalus bubalis, was undertaken using ELISA, immunodot and countercurrent immunoelectrophoresis (CCIEP). The hyperimmune polyclonal antisera were separately raised in rabbits against excretory/secretory (ES) antigens of both the flukes under study. An overall 70% buffalo faecal samples were tested positive for G. crumenifer and 75% for G. explanatum in Aligarh region. The ELISA results reflected higher infection intensity among individual buffaloes that was also observed at necropsy. Using the respective homologous hyperimmune antiserum, 55% buffaloes tested positive for G. crumenifer and 65% positive for G. explanatum in immunodot assay. Further, the faecal samples with high absorbance values in ELISA and strong immunodot reaction tested positive in CCIEP. The analysis of CCIEP result revealed two and one precipitin bands in G. crumenifer and G. explanatum respectively, indicating prominent antigenic differences in the coproantigens of these two parasites. Taken together, it is suggested that polyclonal antibodies could be conveniently used for the detection of coproantigens by ELISA and immunodot methods, particularly during the non-egg producing phase of the seasonally regulated reproductive cycle of the rumen amphistome G. crumenifer. It is concluded that the coproantigen detection is a good alternative over conventional method for the diagnosis of amphistomosis in livestock; however, further studies are required on a larger sample size of field buffaloes to augment the reproducibility of the present results.

    2008-01-01

    Full Text Available Due to the great demand for buffalo milk by-products the interest in technical-scientific information about this species is increasing. Our objective was to propose selection criteria for milk yield in buffaloes based on total milk yield, 305-day milk yield (M305, and test-day milk yield. A total of 3,888 lactations from 1,630 Murrah (Bubalus bubalis cows recorded between 1987 and 2001, from 10 herds in the State of São Paulo, Brazil, were analyzed. Covariance components were obtained using the restricted maximum likelihood method applied to a bivariate animal model. Additive genetic and permanent environmental effects were considered as random, and contemporary group and lactation order as fixed effects. The heritability estimates were 0.22 for total milk yield and 0.19 for M305. For test-day yields, the heritability estimates ranged from 0.12 to 0.30, with the highest values being observed up to the third test month, followed by a decline until the end of lactation. The present results show that test-day milk yield, mainly during the first six months of lactation, could be adopted as a selection criterion to increase total milk yield.

    This study aimed to investigate the pharmacokinetic characteristics of amoxicillin (AMX) in Thai swamp buffaloes, Bubalus bubalis, following single intramuscular administration at two dosages of 10 and 20 mg/kg body weight (b.w.). Blood samples were collected at assigned times up to 48 h. The plasma concentrations of AMX were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The concentrations of AMX in the plasma were determined up to 24 h after i.m. administration at both dosages. The Cmax values of AMX were 3.39 ± 0.18 μg/mL and 6.16 ± 0.18 μg/mL at doses of 10 and 20 mg/kg, respectively. The AUClast values increased in a dose-dependent fashion. The half-life values were 5.56 ± 0.40 h and 4.37 ± 0.23 h at doses of 10 and 20 mg/kg b.w, respectively. Based on the pharmacokinetic data and PK-PD index (T > MIC), i.m. administration of AMX at a dose of 20 mg/kg b.w might be appropriate for the treatment of susceptible Mannheimia haemolytica infection in Thai swamp buffaloes. © 2016 John Wiley & Sons Ltd.

    Full Text Available 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.

    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.

    Infection with Toxoplasma gondii in water buffaloes (Bubalus bubalis) is of epidemiological importance because of the risk for transmission to humans. We sought to determine the seroprevalence of T. gondii infection in 339 water buffaloes in Veracruz State, Mexico using the modified agglutination test (MAT, cut off 1:25). Seroprevalence association with general characteristics of buffaloes and their environment was also investigated. Antibodies to T. gondii were found in 165 (48.7%) of the 339 buffaloes with MAT titers of 1:25 in 104, 1:50 in 52, and 1:100 in 9. Bivariate analysis showed that seroprevalence of T. gondii infection was similar in buffaloes regardless of their general characteristics i.e., age, sex, and breed. In contrast, the seroprevalence in buffaloes varied significantly with environmental characteristics including altitude, mean annual temperature, and mean annual rainfall of the municipalities studied. Multivariate analysis showed that T. gondii seropositivity in buffaloes was associated with a mean annual rainfall between 1266-1650 mm (OR = 1.84; 95% CI: 1.15-2.94; P = 0.01). Results indicate that environmental characteristics may influence the seroprevalence of T. gondii infection in buffaloes. This is the first report on the seroprevalence of T. gondii infection in buffaloes in Mexico. Further research is needed to assess the risk for infection in humans associated with the ingestion of raw or undercooked meat from buffaloes infected with T. gondii.

    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. In the groups of leptin treated with 0 (control, 10, 50 and 100 ng/ml, the percentage of oocytes maturation was 74.65, 83.81, 77.85, and 75.40%, while the

    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.

    The study investigated the effect of dietary supplementation of bypass fat on productive performance and blood biochemical profile of lactating Murrah buffaloes (Bubalus bubalis). Fifteen multiparous buffaloes (2-4 lactation) of early to mid lactation were divided in three homogenous groups T(1) (control), T(2), and T(3) of five each. The animals in T(1) were fed with a basal diet consisting of a concentrate mixture, green sorghum, and wheat straw as per requirements, while the animals in group T(2) and T(3) were fed with same ration supplemented with 0.7 % (100 g/day) and 1.4 % (200 g/day) bypass fat (on dry matter intake (DMI) basis), respectively. The feed intake, milk yield, and milk composition were not influenced by supplemental bypass fat. However, fat-corrected milk (6.5 %) yield was higher (P fat which is 1.4 % (200 g/day) of the diet were economically more efficient. The serum cholesterol level was higher (P fat-supplemented group (T(2) and T(3)) of animals. Serum high density lipoprotein (HDL) cholesterol (good cholesterol) level was more (P bad cholesterol) level with higher dose of bypass fat in T(3) than T(2). It was concluded that bypass fat supplementation with 1.4 % of the diet (200 g/day) increased the fat-corrected milk production and feed efficiency along with serum HDL cholesterol level in lactating Murrah buffaloes.

    The aim was to establish the capacity of buffalo heifers to adapt their metabolic requirements to a low energy diet. Murrah buffalo (Bubalus bubalis) heifers undergoing regular estrous cycles were randomly assigned by age, live weight (LW) and body condition score (BCS) to a high energy group (HE, 5.8 milk forage units (MFU)/day, n=6) or low energy group (LE, 3.6 MFU/day, n=6). Circulating concentrations of metabolic substrates, metabolic hormones and reproductive hormones were determined weekly for 19 weeks. Ovarian follicular characteristics and oocyte parameters were also ascertained weekly. Heifers fed the LE diet had a better dry matter conversion than heifers fed the HE diet and the calculated daily energy provision was negative for heifers fed the LE diet (-0.248 MFU) and positive for heifers fed the HE diet (5.4 MFU). Heifers fed the HE diet had an increase in 50 kg LW over the duration of the study whereas LW remained constant for heifers fed the LE diet. The BCS of heifers fed the HE diet (4.2) was greater (Prequirements when dietary energy is limiting. This adaptive capacity would explain why buffaloes remain productive in environments that are limiting to other ruminants. Copyright © 2010 Elsevier B.V. All rights reserved.

    Full Text Available The objective of the present study was to determine the effect of non-enzymatic antioxidants (vitamin C or E in tris-citric acid buffer (TCA on post-thaw quality of buffalo (Bubalus bubalis bull spermatozoa. 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.

  18. Local immune responses of the Chinese water buffalo, Bubalus bubalis, against Schistosoma japonicum larvae: crucial insights for vaccine design.

    Full Text Available Asian schistosomiasis is a zoonotic parasitic disease infecting up to a million people and threatening tens of millions more. Control of this disease is hindered by the animal reservoirs of the parasite, in particular the water buffalo (Bubalus bubalis, which is responsible for significant levels of human transmission. A transmission-blocking vaccine administered to buffaloes is a realistic option which would aid in the control of schistosomiasis. This will however require a better understanding of the immunobiology of schistosomiasis in naturally exposed buffaloes, particularly the immune response to migrating schistosome larvae, which are the likely targets of an anti-schistosome vaccine. To address this need we investigated the immune response at the major sites of larval migration, the skin and the lungs, in previously exposed and re-challenged water buffaloes. In the skin, a strong allergic-type inflammatory response occurred, characterised by leukocyte and eosinophil infiltration including the formation of granulocytic abscesses. Additionally at the local skin site, interleukin-5 transcript levels were elevated, while interleukin-10 levels decreased. In the skin-draining lymph node (LN a predominant type-2 profile was seen in stimulated cells, while in contrast a type-1 profile was detected in the lung draining LN, and these responses occurred consecutively, reflecting the timing of parasite migration. The intense type-2 immune response at the site of cercarial penetration is significantly different to that seen in naive and permissive animal models such as mice, and suggests a possible mechanism for immunity. Preliminary data also suggest a reduced and delayed immune response occurred in buffaloes given high cercarial challenge doses compared with moderate infections, particularly in the skin. This study offers a deeper understanding into the immunobiology of schistosomiasis in a natural host, which may aid in the future design of more

Total erythrocytic count and packed cell volume values were higher (P<0.05 in levamisole and vit E+Se treated group of buffaloes. Haemoglobin concentration was higher (P<0.05 inVit E+Se treated group. MCV, MCH and MCHC remained unchanged among all the experimental groups. Total leukocyte count was higher (P<0.05 in levamisole treated group of buffaloes. Differential leukocyte counts (relative revealed moderate lymphocytosis in all immunomodulated groups with significantly higher counts in Vit E+Se treated buffaloes. It was inferred that levamisole and vit E-se altered some haematological values, whereas BCG did not affect the haematological parameters.

    Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a cytokine that is essential for growth and development of progenitors of granulocytes and monocytes/macrophages. In this study, we report molecular cloning, sequencing and characterization of GM-CSF from Indian water buffalo, Bubalus bubalis. In addition, we performed sequence and structural analysis for buffalo GM-CSF. Buffalo GM-CSF has been compared with 17 mammalian GM-CSFs using multiple sequence alignment and phylogenetic tree. Three-dimensional model for buffalo GM-CSF and human receptor complex was built using homology modelling to study cross-reactivity between two species. Detailed analysis was performed to study GM-CSF interface and various interactions at the interface. © 2013 John Wiley & Sons Ltd.

    The major histocompatibility complex (MHC) with its three classes represents a cluster of tightly linked genes with defined immunological and non-immunological functions. The DM, a MHC class II molecule is formed by the non-covalent association of DMα and DMβ chains. It binds with the processed peptide antigens and presents them to T lymphocytes, thereby triggering the immune responses. Startlingly, the expression pattern and structural organization of DMα and DMβ proteins in buffalo remains undefined. We isolated and purified the DMα and DMβ proteins from Bubalus bubalis using gel filtration chromatography. Employing western blotting and immunohistochemistry, highest expression of these proteins was observed in spleen and were later localized in the cytoplasm. We modelled 3D structures of the proteins and assessed the binding interface of BuLA-DM docked complex. In the process, we uncovered 9 DMα and 8 DMβ specific residues participating in the formation of BuLA-DM complex. Our work demonstrated active participation of the critical amino acid residues engaged in the formation of BuLA-DM complex facilitating deeper understanding on the structure-function relationship of these proteins.

    Thirty-two water buffalo (Bubalus bubalis) calves aged 6–10 months were used to evaluate serological responses to Brucella abortus strain RB51 (RB51) vaccination in a dose-response study and to compare the use of two selective media for the isolation of RB51. The animals were randomly divided into three treatment groups. Groups I-III received the recommended vaccine dose (RD) twice 4 weeks apart, RD twice 18 weeks apart and saline once, respectively. Lymph nodes were excised from the three groups and subjected to bacteriological examination to determine the frequency of detection of RB51. Pre- and post-vaccination blood samples were collected and tested for B. abortus antibodies using the buffered plate agglutination test (BPAT), complement fixation test (CFT), and dot-blot assay. Sera taken at all post-inoculation weeks (PIW) were negative for field strain B. abortus using the BPAT. Antibody responses to RB51 were demonstrated in all vaccinates but not in controls by CFT and dot-blot assay from 1 PIW up to 16 weeks following booster vaccination. The agreement for both assays was 80.7% and there was a linear interdependence with a Pearson's correlation coefficient value of 0.578. The frequency of isolation of RB51 from the two selective media used was not significantly different (P > 0.05).

    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

    Full Text Available Abstract Background Simple sequence repeats (SSRs of GACA/GATA have been implicated with differentiation of sex-chromosomes and speciation. However, the organization of these repeats within genomes and transcriptomes, even in the best characterized organisms including human, remains unclear. The main objective of this study was to explore the buffalo transcriptome for its association with GACA/GATA repeats, and study the structural organization and differential expression of the GACA/GATA repeat tagged transcripts. Moreover, the distribution of GACA and GATA repeats in the prokaryotic and eukaryotic genomes was studied to highlight their significance in genome evolution. Results We explored several genomes and transcriptomes, and observed total absence of these repeats in the prokaryotes, with their gradual accumulation in higher eukaryotes. Further, employing novel microsatellite associated sequence amplification (MASA approach using varying length oligos based on GACA and GATA repeats; we identified and characterized 44 types of known and novel mRNA transcripts tagged with these repeats from different somatic tissues, gonads and spermatozoa of water buffalo Bubalus bubalis. GACA was found to be associated with higher number of transcripts compared to that with GATA. Exclusive presence of several GACA-tagged transcripts in a tissue or spermatozoa, and absence of the GATA-tagged ones in lung/heart highlights their tissue-specific significance. Of all the GACA/GATA tagged transcripts, ~30% demonstrated inter-tissue and/or tissue-spermatozoal sequence polymorphisms. Significantly, ~60% of the GACA-tagged and all the GATA-tagged transcripts showed highest or unique expression in the testis and/or spermatozoa. Moreover, ~75% GACA-tagged and all the GATA-tagged transcripts were found to be conserved across the species. Conclusion Present study is a pioneer attempt exploring GACA/GATA tagged transcriptome in any mammalian species highlighting their

    The use of artificial insemination (AI) in buffalo (Bubalus bubalis) is limited by poor ovarian activity during the hot season, seasonal qualitative patterns in semen, low resistance of sperm cells in the female tract, difficulties in estrus detection, and variable estrus duration. Although AI procedures are commonly used in bovine, use of AI has been limited in buffalo. In the zootechnical field, different studies have been conducted to develop techniques for improvement of fertilizing ability of buffalo spermatozoa after AI. In this study, for the first time, the use of alginate encapsulation and cryopreservation of buffalo spermatozoa is described, and the same procedure was performed with Holstein Friesian (Bos taurus) semen. Results obtained from in vitro analyses indicate that the encapsulation process does not have detrimental effects (compared to controls) on quality parameters (membrane integrity, progressive motility, path average velocity) in either species. Similarly, there were no detrimental effects after cryopreservation in either species. The fertilizing potential of encapsulated and cryopreserved semen was evaluated after AI in 25 buffalo and 113 bovine females. Pregnancy rates were not affected in either species. The results of this study show proof of concept for the use of frozen semen controlled-release devices in buffalo.

A total of 91 parturient buffalo at smallholder farms were studied (61 suspected to be ketotic and 30 healthy). Clinical and biochemical investigations were carried out for each buffalo. Based on clinical findings and the level of beta-hydroxybutyrate (BHB), buffalo were allocated into ketotic (42), subclinical cases (19). Clinically, there was an association between clinical ketosis and anorexia (pketosis compared with subclinical and control cases, there was a significant increase (pketosis.

    There are uncertainties concerning the identity and host species specificity of Sarcocystis species of the water buffalo (Bubalus bubalis) and cattle (Bos taurus). Currently, in cattle three species are recognized with known endogenous stages, viz.: S. cruzi (with canine definitive host), S. hirsuta (feline definitive host), and S. hominis (primate definitive host). Recently, a fourth Sarcocystis species with an unknown life cycle has been reported from cattle. In the water buffalo, four species of Sarcocystis have been described: S. fusiformis (feline definitive host), S. buffalonis (feline definitive host), S. levinei (canine definitive host), and S. dubeyi (definitive host unknown but not cat or dog). Besides, there are studies of Sarcocystis infections in buffalo and cattle from China with results that are difficult to interpret and validate. For example, some of the studies report transmission of Sarcocystis species between cattle and buffalo, but steps to preclude exogenous exposures were not reported. A species of the water buffalo, 'S. sinensis', was proposed at a Chinese national conference in 1990, and published as an abstract without figures and with no archived type specimens for verification. The International Code of Zoological Nomenclature Articles 9 and 10 state that "abstracts of articles, papers, posters, text of lectures, and similar material when issued primarily to participants at meetings, symposia, colloquia or congress does not constitute published work"; therefore, S. sinensis is a nomen nudum.

    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.

    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(P0.05 byparity. Milk production and quality of Greek buffalo is generally satisfactory, and may be economically beneficialfor local breeders.

    Full Text Available The objectives of this study were to assess the role of glucose, bilirubin, cholesterol and alkaline phosphatase as aetiological factors in parturient haemoglobinuria (PHU in buffaloes and gross and histopathological changes taking place in this disease. For this purpose, 120 buffaloes, including 60 PHU affected and 60 apparently healthy buffaloes were used. These animals were subjected to collection of blood, urine and tissue samples. Blood glucose, serum total bilirubin and serum alkaline phosphatase concentrations in PHU affected buffaloes were significantly higher (P<0.05 than in healthy buffaloes. The colour of urine in PHU affected buffaloes ranged from red, dark red to coffee coloured and its pH was strongly alkaline. Urine of affected buffaloes was positive for haemoglobin (100% and albumin (95% but negative for sugar and ketone bodies. Microscopic examination of urine of affected buffaloes revealed no intact erythrocytes. Grossly, carcasses of buffaloes died of PHU were anaemic and jaundiced. Kidneys, liver and spleen were pale, enlarged and congested. Liver was friable and swollen. Epicardium and endocardium showed ecchymotic haemorrhages. Lungs were emphysemated and oedematous. Histopathologically, kidneys showed necrosis of tubular epithelium and deposition of casts alongwith atrophy of glomeruli. Liver exhibited centrilobular necrosis, haemorrhages and congestion. There was haemosiderin deposition in kidneys, liver and spleen. Heart muscles showed degenerative changes, whereas lungs were haemorrhagic, congested and emphysemated. It was concluded that significantly high blood glucose, serum total bilirubin and alkaline phosphatase were found in PHU affected buffaloes. Histopathologically, necrosis of tubular epithelium, deposition of casts along with atrophy of glomeruli, centrilobular necrosis and haemosiderin deposition were the main findings.

    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.

    The objective of this study was to determine if Brucella abortus rough mutant strain RB51 (SRB51) is eliminated in buffalo milk. Thirty Brucella-free female buffaloes were used in this study: ten 4-5 years old were inoculated with the triple of the recommended calfhood dose of SRB51 by subcutaneous route, ten 2-3 years old at the first lactation were previously vaccinated twice as calves with triple the recommended calf dose of RB51, while five 4-5 years old and five 2-3 years old not vaccinated Brucella-free female buffaloes served as controls. Milk samples were taken aseptically on a daily basis for the first 30 days and weekly for the second and third months. The samples were inoculated on selective media for isolation of SRB51 and incubated for 11 days. Moreover, PCR analysis was also performed directly on milk samples. SRB51 was isolated from milk samples only during the first week post-vaccination while RB51 DNA was detected during the first week till the fourth week post-vaccination only in water buffaloes vaccinated as adults. The identification of Brucella RB51 in milk samples, strongly suggests that this Brucella vaccine could be excreted in milk of buffalo cows vaccinated as adults, while our data demonstrate that the vaccine is safe for use in buffaloes vaccinated as calves in which it was not excreted in milk.

    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 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 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. © 2011 Blackwell Verlag GmbH.

    Full Text Available To evaluate the serum concentrations of haptoglobin (Hp and serum amyloid A (SAA in water buffaloes with abomasal ulcers, the abomasums of 100 randomly selected water buffaloes were examined after slaughter. Type I abomasal ulcers were found in 56 out of 100 buffaloes. Serum concentrations of Hp and SAA were measured. There was no significant difference between affected and non-affected buffaloes in the serum concentrations of Hp and SAA. The serum concentrations of Hp and SAA had no significant correlation with age and the serum SAA revealed no significant correlation with the number of abomasal ulcers. A significant correlation was found between the serum Hp and the number of abomasal ulcers (r =0.29, p = 0.04. There was no significant difference in the serum concentrations of Hp and SAA between buffaloes with different ulcer locations in the abomasums. Although more work on a larger number of animals is required in this area, it seems that the measurement of the serum Hp can be used to predict the abundance of type I abomasal ulcers.

    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

    The objective of this study was to examine the follicular fluid biochemical and hormonal changes associated with ovarian follicular cysts in buffalo. Follicular fluid was aspirated from eight cysts and eight preovulatory follicles, and subjected to biochemical and hormonal analyses. Cysts were characterized by a greater (Pfollicular cysts had greater concentrations of progesterone (Pfollicular cysts in buffalo have an altered biochemical and hormonal composition. The alterations include increases in nitric oxide, progesterone, cortisol and T(3) concentrations with a concurrent reduction in ascorbic acid, insulin and glucose concentrations. The study suggests that greater progesterone concentrations possibly inhibit the onset of LH surge resulting in formation of follicular cysts in buffalo. In addition, it implies the plausible role of intra-ovarian regulators such as nitric oxide, ascorbic acid and insulin in development of the condition. Copyright © 2011 Elsevier B.V.

    Full Text Available In order to distinguish Mediterranea Italiana breed from other populations of water buffaloes we develop a tool for genetic traceability of the geographical origin based on microsatellite markers. Fourteen microsatellite loci, amplified with a protocol of one multiplex-PCR, were used to define genetic variation and relationships among Mediterranea Italiana breed and other buffalo groups coming from three different geographical districts: one group from North Africa, two groups from East Europe and one group from China. A total of 153 buffaloes were analysed. GENETIX computer package were used to calculate the following parameters for each population: allelic frequencies, number of alleles for each locus, average observed (Hobs and expected (Hexp heterozygosities, genetic distances and Hardy-Weinberg equilibrium. Population differentiation was analysed by estimation of Fst and Fis index for various group combinations. Population assignment were computed by GENECLASS 2 based on different approach. The individual assignment by different approach has given a result of robustness demarcation distinguishing three definite clusters, therefore this method is useful for distinction of typical products belonging to Mediterranea Italiana breed from the others derived from the other populations of buffalo.

    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.

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

    Libraries of rumen bacterial 16S rRNA gene sequences of Gayals (Bos frontalis) and Swamp buffaloes (Bubalus bubalis) were cloned and sequenced in the present work to compare the bacterial diversity with the third published library of Holstein cow. Sequence similarity of 97% was used as the definition of operational taxonomic unit (OTU). The majority of the 470 sequences retrieved fell into the phyla of low G + C subdivision (329 sequences) and Cytophaga-Flexibacter-Bacteroides (CFB, 123 sequences) with the percentages of 70 and 26.2, respectively. The remaining clones belonged to the phyla of Proteobacter, high G + C gram positive bacteria (HGCGPB) and Spirochaetes, accounting for 3.8% totally. Only 73 clones (25 OTUs, 15.5%) could be closely related to cultured representatives. However, a larger fraction was related to uncultured representatives. Holstein cow may have more representatives of cultural bacteria and there were more uncultured clones for Gayals. The percentage of cultural representatives was 24, 13.3 and 9.5 for Holstein cow, Swamp buffaloes and Gayals, respectively. Twenty-three OTUs of the 236 ones appeared in more than one library, five of which were cultural. Selenomonas ruminantium, Ruminococcus flavefaciens and Butyrivibrio fibrisolvens were found in two different libraries, while Succiniclasticum ruminis and Pseudobutyrivibrio ruminis were found in all three libraries. Some of the animal-specific bacteria that had not been described previously in the ruminal ecosystem, e.g. Allisonella histaminiformans for Gayals and Staphylococcus sciuri for Swamp buffaloes were also recovered.

    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.

    The aims of the investigation were to establish for the first time (i) clinical efficacy and (ii) pharmacokinetic profile of meloxicam intravenously (IV) administered in male Mediterranean buffalo calves after surgical orchiectomy. The study was performed on 10 healthy buffalo calves, between 4 and 5 months old and between 127 and 135 kg of body weight (b.w.). An IV injection of 0.5 mg/kg b.w. of meloxicam was administered in six calves (treated group, TG) immediately after surgery; the other four animals were used as untreated control group (CG). The clinical efficacy of meloxicam was evaluated pre- and post-surgery by monitoring respiratory rate (RR), heart rate (HR), rectal temperature (T°C), serum cortisol levels (SCL) and pain score (PS). Significant inter-groups differences were detected at sampling times (T): 4 hour (h) for RR (Pmeloxicam mean concentrations at 96 h was of 0.18 ± 0.14 μg/mL. The volume of distribution and clearance values were quite low, but reasonably homogenous among individuals (Vdss 142.31 ± 55.08 mL/kg and ClB 4.38 ± 0.95 mL/kg/h, respectively). The IV administration of meloxicam in buffalo calves shows encouraging effects represented by significant and prolonged analgesic effects, significant reduction of SCL as well as similar pharmacokinetic profile to bovine calves.

    The blood samples from fifteen normal lactating buffaloes were taken from December 15th 1978 to 31st August, 1979. Depending upon the climatic conditions, the whole period of study was divided into four seasons. The mean values of carbonic anhydrase (moles CO2/l/sec×10-5) were 3.08±0.26, 4.94±0.44, 5.23±0.35, 6.44±0.32 in pregnant and 4.87±0.27, 4.53±0.41, 4.74±0.45, 6.36±0.40 in non-pregnant animals during winter, spring, hot and dry and hot and humid seasons. Mean values of pO2 (mm Hg) were 31.26±1.41, 31.92±0.61, 35.90±0.59, 33.80 ±0.67 in pregnant and 31.89±0.44, 31.53±0.54, 35.52±0.69, 31.65±0.95 in non-pregnant buffaloes during winter, spring, hot and dry and hot and humid periods, respectively. There were highly significant (P< 0.01) differences between seasons with respect to pO2, pCO2, actual HCO3 and heamoglobin. However, PCV changed significantly (P<0.01) with the physiological status of the animal. Different correlation of biochemical parameters with climatic elements were discussed. Thus, the shifts in the levels of carbonic anhydrase, HCO3 and heamoglobin may prove to be a better tool/index for thermal stress in buffaloes.

    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.

    In this study, glutathione-S-transferase Mu3 (GST) has been reported to play an important role in sperm capacitation, acrosome reaction, and fertilization. The freshly ejaculated buffalo spermatozoa were in vitro capacitated using heparin (10 μg/mL) or cryopreserved in egg yolk citrate extender. Glutathione-S-transferase was identified and characterized in terms of their isozymic forms, tyrosine phosphorylation, and immunolocalization patterns in cryopreserved buffalo spermatozoa in comparison with freshly ejaculated and in vitro capacitated spermatozoa. Two-dimensional gel electrophoresis, immunoblot, immunocytochemistry, and enzyme activity analyses were done to characterize GST in this study. Five and eight isozymic forms of GST were detected in cryopreserved and capacitated spermatozoa, respectively. Differential tyrosine phosphorylation of these enzymes was observed in cryopreserved and capacitated spermatozoa. The tyrosine phosphorylation of this enzyme involved cAMP protein kinase-A dependent and extracellular signal-regulated kinase independent pathways during in vitro capacitation of the spermatozoa. Differential immunolocalization patterns of GST were observed in freshly ejaculated, capacitated, and cryopreserved spermatozoa. Glutathione-S-transferase Mu3 enzyme activity was found to be significantly (P sperm cryopreservation could be a good target to improve fertility of cryopreserved spermatozoa for their use in assisted reproductive technologies.

    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.

    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.

    Vitiligo is a multifactorial acquired depigmenting disorder. Recent insights into the molecular mechanisms driving the gradual destruction of melanocytes in vitiligo will likely lead to the discovery of novel therapies, which need to be evaluated in animal models that closely recapitulate the pathogenesis of human vitiligo. In humans, vitiligo is characterized by a spontaneous loss of functional melanocytes from the epidermis, but most animal models of vitiligo are either inducible or genetically programmed. Here, we report that acquired depigmentation in water buffalo recapitulates molecular, histological, immunohistochemical, and ultrastructural changes observed in human vitiligo and hence could be used as a model to study vitiligo pathogenesis and facilitate the discovery and evaluation of therapeutic interventions for vitiligo. © 2016 John Wiley & Sons A/S.

    Full Text Available Genealogy and productive information of 48621 dual-purpose buffaloes born in Colombia between years 1996 and 2014 was used. The following traits were assessed using one-trait models: milk yield at 270 days (MY270, age at first calving (AFC, weaning weight (WW, and weights at the following ages: first year (W12, 18 months (W18, and 2 years (W24. Direct additive genetic and residual random effects were included in all the traits. Maternal permanent environmental and maternal additive genetic effects were included for WW and W12. The fixed effects were: contemporary group (for all traits, sex (for WW, W12, W18, and W24, parity (for WW, W12, and MY270. Age was included as covariate for WW, W12, W18 and W24. Principal component analysis (PCA was conducted using the genetic values of 133 breeding males whose breeding-value reliability was higher than 50% for all the traits in order to define the number of principal components (PC which would explain most of the variation. The highest heritabilities were for W18 and MY270, and the lowest for AFC; with 0.53, 0.23, and 0.17, respectively. The first three PCs represented 66% of the total variance. Correlation of the first PC with meat production traits was higher than 0.73, and it was -0.38 with AFC. Correlations of the second PC with maternal genetic component traits for WW and W12 were above 0.75. The third PC had 0.84 correlation with MY270. PCA is an alternative approach for analyzing traits in dual-purpose buffaloes and reduces the dimension of the traits.

    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.

    2011-03-01

    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........

    We compared the therapeutic effect of three anticoccidial drugs (toltrazuril, sulphadimidine and amprolium) in buffalo (Bubalus bubalis) calves experimentally infected with Eimeria bovis (E. bovis) and E. zuernii oocysts (3 x 104oocyst/calf). Buffalo calves (1.5-4 month old, 70-kg body weight) were randomly allocated into 3 groups (9 calves each). Group T was experimentally infected with oocysts and treated with toltrazuril (20 mg/kg BW twice orally at a 1-week interval). Group S was experimentally infected with oocysts and treated with sulphadimidine (125 mg/kg injected IM followed by half dose for 4 successive days). Group A was experimentally infected with oocysts and treated with amprolium (50 mg/kg orally for 7 successive days). Each group had three subgroups (three calves/subgroup) to represent timing of the drug administration: 1st day of coccidia infection (FD), onset of clinical signs of coccidiosis (CC), and onset of oocyst shedding into the faeces (OS). Clinical signs, body-weight gain (BWG) and number of oocysts per gram feces (OPG) were monitored daily for 35 days post-infection (DPI). The OPG were reduced (but the BWG was not different) in the T calves compared to S and A calves. Within the same group, treatment from the 1st day of infection reduced the OPG and increased the BWG compared to the later treatment timings.

    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.

    Binder of sperm-5 (BSP-5) is one of the fertility-associated proteins of cattle seminal plasma. Binding of sperm to the oviductal epithelium is mediated by BSP group of proteins. However, it is not clear, whether this protein is also involved in sperm motility. In the present study, attempts were made to characterize BSP-5 protein in both normozoospermic (NS) and asthenozoospermic (AS) Murrah buffalo (n = 18; Bubalus bubalis), Holstein Friesian (n = 8, Bos taurus) and Jersey cattle (n = 8; Bos taurus) bull seminal plasma and also study its expression pattern in these species. 1-D Western blot demonstrated three major BSP-5 immunoreactive protein bands (24.2 kDa, 20.5 kDa, and 12.3 kDa) in buffalo seminal plasma. Of these, the intensities of 24.2 and 20.5 kDa protein bands reduced significantly (P ≤ 0.05) in seminal plasma of AS group compared to that of NS group. On the contrary, the expression of 12.3 kDa protein band did not vary significantly between the groups. In Holstein Friesian seminal plasma, at least six BSP-5 immunoreactive protein bands (25.1, 23.6, 19.5, 13.8, 13.1 and 12.3 kDa) could be detected. Of these, the intensities of 23.6, 13.8/13.1 and 12.3 kDa protein bands decreased (P = 0.058, 0.111, 0.053) in AS group bulls compared to NS bulls. Holstein Friesian bull seminal plasma demonstrated a BSP-5 immunoreactive duplex protein band of 13.8/13.1 kDa, which was not evident in buffalo seminal plasma. In 2-D Western blot, a train of five BSP-5 immunoreactive duplex protein spots (Mr 21.0-27.6 kDa, pI of ∼3.9-5.1) was detected. Mass spectrometry of one of the representative duplex spot confirmed that these were BSP-5 and BSP-3 proteins, respectively. Indirect immunofluorescence studies showed that BSP-5 is primarily localized to the mid-piece/mitochondrial region of buffalo spermatozoa. To conclude, the findings of the present study could establish the significance and association of BSP-5 proteins in sperm motility and how their

    Full Text Available This study was executed to know the clinico-epidemiology of parturient haemoglobinuria (PHU in buffaloes. A total of 60 buffaloes suffering from PHU were randomly selected from field cases occurring in Faisalabad, Toba Tek Singh and Jhang districts of Punjab, Pakistan. Sixty clinically healthy buffaloes of similar description from the same localities were also included in the study as control. The most prominent clinical sign was passing of red to coffee coloured urine. Milk production in affected buffaloes was significantly (P<0.001 reduced, while respiration and pulse rates were accelerated (P<0.001. Ruminal motility was significantly weak and reduced alongwith characteristic straining while defecating. The case fatality was 15%. A significantly higher 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 haemoglobinuria 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 litres of milk/day (42.5%. Recurrence of PHU was observed in 18.3% buffaloes. Berseem constituted a major component (65% of fodders of most of the PHU affected buffaloes. Significantly lowered serum phosphorus, copper and selenium, while higher potassium, iron and molybdenum, were found in affected buffaloes as compared to healthy buffaloes. It was concluded that PHU mostly affects high yielding buffaloes in their 3-5th lactation particularly in early lactation or advanced pregnancy. Disease is strongly associated with Berseem feeding in winter season.

    Full Text Available The aim of this study was to evaluate the possibility to vitrify in vitro produced (IVP buffalo and bovine embryos at different stages of development by an advanced version of the “minimal volume approaches”: the Cryotop method. In both experiments, the embryos were vitrified at the tight morula (TM, early blastocyst (eBl, blastocyst (Bl, expanded blastocyst (xBl and, only for buffalo, at the hatched blastocyst (hBl stage. After warming, the embryos were cultured in vitro for 24 hours. Stage of development affected the freezability of IVP embryos of both species with the highest embryo survival rates at advanced stages (xBl=76% and hBl=75% for buffalos and xBl=75% for bovine. These results suggest that Cryotop vitrification is an efficient method for buffalo and bovine IVP embryo cryopreservation.

    In order to describe the lactation curves of milk yield (MY) and composition in buffaloes, seven non-linear mathematical equations (Wood, Dhanoa, Sikka, Nelder, Brody, Dijkstra and Rook) were used. Data were 116,117 test-day records for MY, fat (FP) and protein (PP) percentages of milk from the first three lactations of buffaloes which were collected from 893 herds in the period from 1992 to 2012 by the Animal Breeding Center of Iran. Each model was fitted to monthly production records of dairy buffaloes using the NLIN and MODEL procedures in SAS and the parameters were estimated. The models were tested for goodness of fit using adjusted coefficient of determination (Radj(2)), root means square error (RMSE), Durbin-Watson statistic and Akaike's information criterion (AIC). The Dijkstra model provided the best fit of MY and PP of milk for the first three parities of buffaloes due to the lower values of RMSE and AIC than other models. For the first-parity buffaloes, Sikka and Brody models provided the best fit of FP, but for the second- and third-parity buffaloes, Sikka model and Brody equation provided the best fit of lactation curve for FP, respectively. The results of this study showed that the Wood and Dhanoa equations were able to estimate the time to the peak MY more accurately than the other equations. In addition, Nelder and Dijkstra equations were able to estimate the peak time at second and third parities more accurately than other equations, respectively. Brody function provided more accurate predictions of peak MY over the first three parities of buffaloes. There was generally a positive relationship between 305-day MY and persistency measures and also between peak yield and 305-day MY, calculated by different models, within each lactation in the current study. Overall, evaluation of the different equations used in the current study indicated the potential of the non-linear models for fitting monthly productive records of buffaloes.

    Estrus detection in buffaloes has been a major concern for decades, and lack of reliable methods affects their effective reproductive management. Luteinizing hormone (LH) detection in urine is in practice for several mammals for timed insemination, whereas very few reports are available on buffalo urinary LH. The focus of this study is to detect the presence of LH in buffalo urine, quantitate variation in urinary LH during different estrous cycle phases and examine the duration of mid-cycle LH window. Nearly hundred buffaloes were examined, longitudinal urine samples (n=42) were collected from seventeen animals and classified into respective phases based on several estrus detection parameters. The urinary LH was detected using bovine LH ELISA kit validated for serum/plasma/tissue homogenate. Detection of buffalo LH in the neat urine convincingly proved the competence of the bovine LH kit. Variation in the LH range was observed between different phases of estrous cycle and significant fold variation (Psurge was observed due to its lingering excretion in urine. The results, altogether, revealed that LH can be detected in buffalo urine with noticeable fold variation during estrus phase and the extended LH window intensifies the chance of ovulation prediction for timed insemination.

    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.

    Buffalo milk represents an indispensable source of nourishment in many parts of the world and it is the second most consumed milk worldwide. Buffalo milk is actually used for the production of many dairy products such as pasteurized or concentrated milk, butter, yogurt, ice-cream, dehydrated milk products and cheeses. Due to its high nutritional value and the presence of natural bioactive substances, buffalo milk can also provide health benefits to consumers. In Italy, buffalo milk is used mainly for cheese making, mozzarella PDO (Protected Designation of Origin), which is a highly valued dairy product. This 3-year study, carried out between 2011 and 2013, was aimed at evaluating the quality of bulk Italian Mediterranean buffalo milk by monitoring physico-chemical parameters, somatic cell and total bacterial counts. A total of 51 samples of bulk milk were collected from one herd throughout the monitored period. Analysis of variance, carried out to test month, season and year main effects, highlighted remarkable seasonal effects for fat, protein and lactose content, as well as for predicted mozzarella cheese yield, and somatic cell counts. The calculation of simple correlations allowed the identification of positive correlations between estimated cheese yield and fat and protein content. © 2017 Japanese Society of Animal Science.

    The objective was to explore the use of sexed sperm and OPU-derived oocytes in an IVP system to produce sex-preselected bubaline embryos. Oocytes were recovered from 20 fertile Murrah and Nili-Ravi buffalo cows by repeated (twice weekly) ultrasound-guided transvaginal ovum pick up (OPU), or by aspiration of abbatoir-derived bubaline ovaries, and subjected to IVF, using frozen-thawed sexed or unsexed bubaline semen. On average, 4.6 oocytes were retrieved per buffalo per session (70.9% were Grades A or B). Following IVF with sexed sperm, oocytes derived from OPU had similar developmental competence as those from abattoir-derived ovaries, in terms of cleavage rate (57.6 vs. 50.4%, P=0.357) and blastocyst development rate (16.0 vs. 23.9%, P=0.237). Furthermore, using frozen-thawed sexed versus unsexed semen did not affect rates of cleavage (50.5 vs. 50.9%, P=0.978) or blastocyst development (15.3 vs. 19.1%, P=0.291) after IVF using OPU-derived oocytes. Of the embryos produced in an OPU-IVP system, 9 of 34 sexed fresh embryos (26.5%) and 5 of 43 sexed frozen embryos (11.6%) transferred to recipients established pregnancies, whereas 7 of 26 unsexed fresh embryos (26.9%) and 6 out of 39 unsexed frozen embryos (15.4%) transferred to recipients established pregnancies. Eleven sex-preselected buffalo calves (10 females and one male) and 10 sexed buffalo calves (six females and four males) were born following embryo transfer. In the present study, OPU, sperm sexing technology, IVP, and embryo transfer, were used to produce sex-preselected buffalo calves. This study provided proof of concept for further research and wider field application of these technologies in buffalo.

    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 An experiment was conducted to study the addition of NaHCO3 and Na2CO3 on acid-base status in swamp buffaloes, Three fistulated buffaloes were each introduced to dietary treatment control diett (50% rice straw + 50% concentrate, control + \\0% NaHCO3 and diet control + 10% Na2CO3 in two times Latin Square Design. The diets contained 9,7% crude protein and 53% TDN to achieve maintenance requirements of the animals. Parameters measured include (l Fed consumption, water consumption and urine volume. (2 pH in rumen fluid, saliva, bLood and urine, (3 natrium mineral content in rumen fluid, saliva, blood and urine. The results of the experiment showed higher pH in the rumen fluid, saliva, blood and urine of buffaloes due to supplementation of NaHCO3 and Na2CO3, Water consumption and urine volume was significanly increased as the effect of Na supplement. The acid-base status of buffaloes was apparently normal in all animals.

    The objective of the experiments reported here was to measure the effects of cooling techniques (Modified roof vs Normal roof) on the performance and physiology of 12 young male buffaloes with a similar live weight of 160 kg. The study was conducted at Chainat Agriculture and Technology College, Chainat Province, Thailand. The animals were divided randomly into two groups, each group comprising six buffaloes, and the two groups were studied to evaluate the effects of modified roofing (normal roof fitted with woven polypropylene shade cloth) on the subjects' physiological responses to heat stress under hot humid conditions. The modified roof resulted in lowered heat stress in buffaloes compared to those under a standard roof. The difference was shown by the buffaloes having a significantly lower mean rectal temperature (39.14 ± 0.07 vs 40.00 ± 0.10°C) and plasma cortisol (2.14 ± 0.24 vs 3.38 ± 0.37 ng/ml). The average daily water consumption was significantly lower in the MR group (MR, 29.71 ± 0.86 vs NR, 34.14 ± 1.06 L head -1 day-1), while there was a tendency for the roughage intake to be higher in the MR group compared to that of the NR group (MR, 5.88 ± 0.18 vs NR, 6.44 ± 0.19 kg head-1 -1 day-1; P = 0.0508). It was concluded that roof modification facilitated a reduction in heat load from roof re-radiation, and was an effective means of alleviating thermal stress in young buffaloes.

    Full Text Available Autonomic nerves supplying mammalian male internal genital organs have an important role in the regulation of reproductive function. To find out the relationships between the neurochemical content of these nerves and the reproductive activity, we performed an immunohistochemical study in a species, the water buffalo, exhibiting a seasonal sexual behaviour. The distribution of noradrenergic and peptide-containing nerves was evaluated during the mating (autumn-winter and non-mating (spring-summer periods. During the mating period, a dense noradrenergic innervation was observed to supply the vas deferens as well as the accessory genital glands. Peptide-containing nerves were also observed but with a lower density. During the non-mating period noradrenergic nerves dramatically reduced. These results suggest that there is a neuro-endocrine interaction between androgen hormones and the autonomic nerve supply in the regulation of male water buffalo reproductive functions.

    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.

    A project implemented from 2003–2005 trained women in Chitwan District, Nepal, in hygienic dairy production using a process of social mobilization. The aim of this research was to assess if the prevalence of mastitis in water buffalo in the households of women who were trained was lower one year after training than in untrained households, if the training influenced knowledge and practices for the prevention or control of mastitis, and if these practices and knowledge were associated with a lower prevalence of mastitis. A total of 202 households from Eastern and Western Chitwan District were included in the study. Of these, 60 households had participated in the project and 142 had not. Milk samples were collected from 129 households (33 project households and 96 non-project households). Clinical mastitis was determined using visual inspection of udders and detection of macroscopic clots and flakes in milk. The California Mastitis Test was used to diagnose sub-clinical mastitis from milk samples, and the IDEXX SNAP test to identify the presence of tetracycline residues. The prevalence of mastitis in trained households (39.4%) was 43.78% of that in untrained households (60.4%), lower but not significantly so (p = 0.08, 95% CI 0.17–1.12). Thirteen indicators of knowledge or practice for the control or prevention of mastitis were more likely to occur in trained households, four significantly so (not consuming milk from sick buffalo (p=0.001), using soap to wash hands before milking (p=0.001), discarding milk after antibiotic usage (p=0.01), and choosing appropriate flooring for their livestock (p=0.03)). Trained households that discarded milk from sick buffalo were 2.96 times more likely to have at least one animal with mastitis in the household (p=0.03, 95% CI 1.15–7.65). Trained households that knew to wash buffalos teats after milking were less likely (OR 0.25) to have mastitis in their herd ((p=0.02, 95% CI 0.08–0.80). Of the 138 buffalos tested, only one

    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

    Effects of curcumin as antioxidant in extender were evaluated on freezability of buffalo spermatozoa. Semen from each of the five bulls (n = 3 replicates, six ejaculates/bull, a total of 30 ejaculates) was diluted in Tris-citric acid extender containing curcumin (0.5, 1.0, 1.5 or 2.0 mM) or control. At pre-freezing and post-thawing, total antioxidant contents (μM/L) and lipid peroxidation levels (μM/ml) were higher (p straight-line velocity, μm/s; curved-line velocity, μm/s; straightness, %; linearity, %), in vitro longevity (%, PM and RV) and DNA integrity (%) at post-thawing were higher (p < .05) with 1.5 mM compared to control. At post-thawing, supravital plasma membrane integrity (%) and viable spermatozoa with intact acrosome (%) were higher with 1.5 compared to 2.0 mM curcumin and control. We concluded that freezability of water buffalo spermatozoa is improved with the addition of 1.5 mM curcumin in extender. © 2016 Blackwell Verlag GmbH.

    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.

    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. Copyright © 2016 Elsevier Ltd.

    The aim of this study was to evaluate differences in efficiency of feed utilisation between buffalo calves with low and high residual feed intake (RFI) by comparing feed intake, nutrient digestibility, growth traits and blood metabolites. Eighteen male Murrah buffalo calves (aged 4-6 months; 70 ± 1.0 kg body weight) were fed ad libitum with a total mixed ration for 120 d. Based on linear regression models involving dry matter intake (DMI), average daily gain (ADG) and mid-test metabolic body size, calves were assigned into low and high RFI groups. The RFI varied from -0.33 to +0.28 kg DM/d with an average RFI of -0.14 and 0.14 kg DM/d in low and high RFI calves, respectively. Calves had a mean DMI of 1.9 and 2.4 kg/d and an ADG of 0.5 and 0.6 kg/d in low and high RFI groups, respectively. Low RFI calves ate 19.0% less DM each day and required significantly less metabolisable energy for maintenance compared with high RFI calves (12.5 vs. 16.7 MJ/d). Nutrient digestibility and nitrogen balance did not differ among low and high RFI calves. In more efficient animals (low RFI calves) higher (p calves are more efficient in feed utilisation and the differences in blood metabolites are probably due to differences in feed intake and body metabolism.

    Twenty-four ejaculates from six (four ejaculates each) Surti buffalo bulls aged 4-8 years were used to assess various attributes of spermatozoa influencing the zona-binding and zona-penetration tests. Ejaculates from each bulls were subjected to in vitro sperm--zona binding and sperm--zona penetration tests (four replicates per bull) using immature buffalo oocytes. The average number of spermatozoa bound per oocyte was 27.79 +/- 5.90. The average number of spermatozoa penetrated per oocyte was 3.35 +/- 0.64. The average number of zona-bound and -penetrated spermatozoa differed significantly between animals. Significant difference (p < 0.05) was observed between the plasmalemma integrity as assessed by eosin--nigrosin stain and hypo-osmotic swelling (HOS) test. Furthermore, the percentage of cells positive for the HOS test, i.e. functional membrane integrity (51.25 +/- 2.32) was significantly (p < 0.05) higher than hypo-osmotic swelling-Giemsa (HOS-G) test, i.e. the subpopulation of spermatozoa positive for functional membrane and acrosomal integrities (42.87 +/- 4.56). The HOS test had significant correlations with plasmalemma integrity as measured by the vital stain, eosin--nigrosin (r = 0.85, p < 0.05). The HOS-G test also had significant correlation with plasmalemma integrity measured by vital stains such as eosin--nigrosin (r = 0.90, p < 0.05) and fluorogenic stains [carboxyfluorescein diacetate (CFDA) and propidium iodide (PI); r = 0.92, p < 0.01] and HOS test (r = 0.93), acrosomal integrity (r = 0.86, p < 0.05) and mitochondrial membrane potential (r = 0.99, p < 0.01). The plasmalemma integrity (fluorogenic stain), functional membrane integrity (HOS test), subpopulation of spermatozoa positive for functional membrane and acrosomal integrities (HOS-G test) and mitochondrial membrane potential had significant (p < 0.05) correlation with sperm zona binding and penetration. The present study indicates that these parameters could represent important determinants

    Full Text Available Buffalo ovaries were collected from a slaughterhouse (Frigol, Brazil and transported to the laboratory in saline solution at 36º C. The ovaries were dissected to realize the evaluations (weight, length, width and height of the ovary; corpus luteum and dominant follicle diameters. The Cumulus-oocyte complexes (COCs were recovered by aspiration of 2-8 mm follicles. Selected COCs were matured in TCM 199 supplemented with 10% fetal bovine serum, sodium pyruvate, LH, FSH, estradiol and gentamicin. In vitro maturation was carried out at 38.5° C for 22-24 h and 34-36 h. For the evaluation of the nuclear maturation the oocytes were placed in TCM 199 medium added with type v hialuronidase where the granulosa cells were extracted. The denuded oocytes were transferred to 10 μl of Hoescht 33342 and the chromosomic configuration was evaluated. The oocytes were classified according to meiosis stage in: Germinal Vesicle, Germinal Vesicle Breakdown, Metaphase I, Metaphase II and Degenerated. The means of weight, length, width and height of the ovary were 3.83 g, 2.27 cm, 1.08 cm and 1.56 cm, respectively. The means of corpus luteum and dominant follicle diameters were 1.40 cm and 7.77 mm. The proportion of oocytes that reached metaphase II stage was: 36.68%.

    Abstract 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.

    The study examined the effects of different environmental stress on developmental competence and the relative abundance (RA) of various gene transcripts in oocytes and embryos of buffalo. Oocytes collected during cold period (CP) and hot period (HP) were matured, fertilized and cultured in vitro to blastocyst hatching stage. The mRNA expression patterns of genes implicated in developmental competence (OCT-4, IGF-2R and GDF-9), heat shock (HSP-70.1), oxidative stress (MnSOD), metabolism (GLUT-1), pro-apoptosis (BAX) and anti-apoptosis (BCL-2) were evaluated in immature and matured oocytes as well as in pre-implantation stage embryos. Oocytes reaching MII stage, cleavage rates, blastocyst yield and hatching rates increased (P < 0.05) during the CP. In MII oocytes and 2-cell embryos, the RA of OCT-4, IGF-2R, GDF-9, MnSOD and GLUT-1 decreased (P < 0.05) during the HP. In 4-cell embryos, the RA of OCT-4, IGF-2R and BCL-2 decreased (P < 0.05) in the HP, whereas GDF-9 increased (P < 0.05). In 8-to 16-cell embryos, the RA of OCT-4 and BCL-2 decreased (P < 0. 05) in the HP, whereas HSP-70.1 and BAX expression increased (P < 0.05). In morula and blastocyst, the RA of OCT-4, IGF-2R and MnSOD decreased (P < 0.05) during the HP, whereas HSP-70.1 was increased (P < 0.05). In conclusion, deleterious seasonal effects induced at the GV-stage carry-over to subsequent embryonic developmental stages and compromise oocyte developmental competence and quality of developed blastocysts.

Two groups were used in this study, twelve samples for anatomical study and ten samples for histological study, in each group of this study, the tongues were divided into four regions from apex to the end of the root. The tongue is a muscular organ which consists of dorsal and ventral surfaces, it is formed from three parts (apex, body and root. The lingual fossa and torus linguae both appear on the dorsal surface. The total average of the tongue length in adult animals (36.00±0.97 cm while the highest average of the length, width and thickness found in the third region. The total length in small ages was (16.92±0.98 cm and the highest average of length and thickness again it happens in third region and the highest width in this age group found in the second region. The investigation of the normal anatomical structures of the tongue distinguished four lingual papillae (filiform, fungiform, conical and circumvalate while the lenticuler papillae absent in both age groups. The filiform and fungiform papillae spread over the dorsal surface and ventro-lateral surface terminat abruptly at the ventro-lateral border forming a distinct straight line from apex to the torus linguae in both ages. The present work reveals that the highest average of filiform papillae in both surface (dorsal and ventro-lateral surface founds in second region in adult group, while in small group founds in first region. The highest average of fungiform papillae in both surface of both age groups are in the apex of tongue. The highest average of conical and circumvalate papillae in both age group (adult and young were on torus linguae. The histological study has been used the shape, diameter and the type of epithelium which covered the papillae in both groups. The filiform papillae are long fine projection beading

    Full Text Available The research was accomplished in eight dairy water buffalo herds, randomically choosen in Região do Alto São Francisco, State of Minas Gerais, Brazil. Information was collected from March to November, 2003 during 270 days of observation. 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.

    The sucking louse Haematopinus tuberculatus (Burmeister 1839) is an ectoparasite of buffaloes, cattle, camels, and American bison. Alphacypermethrin (ACYP) is a pyrethroid insecticide commonly used to control arthropods of veterinary and public health interest. Therapeutics, such as antiparasitic compounds, is often administered to buffaloes based on dosage and intervals recommended for cattle because very few drugs have buffalo-specific label indications. A trial was conducted on 20 louse-infested buffaloes at a farm to assess the efficacy and safety of ACYP pour-on, at the manufacturer's recommended dose for cattle, on buffaloes naturally infested by H. tuberculatus. Ten animals were assigned to ACYP-treated group (ACYP-group) and ten to untreated control group (C-group). On day 0, all ACYP-group buffaloes received alphacypermethrin pour-on. Louse counts were performed on days -1, 7, 14, 21, 28, 35, 42, 49, and 56 at eight predilection sites on the skin of each buffalo. ACYP was completely effective (100%) at day 7, highly effective (99.8%) at day 14, and completely effective (100%) from day 21 until the end of the study (day 56 post-treatment). During the trial, ACYP was well tolerated by all animals as there were no observed clinically adverse reactions. The results of this trial suggest that ACYP is an effective, safe, and user-friendly compound suitable for treatment of buffaloes with natural louse infestations.

    This study was designed to investigate the impact of buserelin acetate (BA) or human chorionic gonadotropin (hCG) administration on the day of first artificial insemination (AI) on subsequent luteal profile (diameter of corpus luteum (CL) and plasma progesterone) and conception rate in Murrah buffalo. The present experiment was carried out at two locations in 117 buffalo that were oestrus-synchronized using cloprostenol (500 μg) administered (i.m.) 11 days apart followed by AI during standing oestrus. Based on treatment (i.m.) at the time of AI, buffalo were randomly categorized (n = 39 in each group) into control (isotonic saline solution, 5 ml), dAI-BA (buserelin acetate, 20 μg) and dAI-hCG (hCG, 3000 IU) group. Out of these, 14 buffalo of each group were subjected to ovarian ultrasonography on the day of oestrus to monitor the preovulatory follicle and on days 5, 12, 16 and 21 post-ovulation to monitor CL diameter. On the day of each sonography, jugular vein blood samples were collected for the estimation of progesterone concentrations. All the buffalo (n = 117) were confirmed for pregnancy on day 40 post-ovulation. The conception rate was better (p hCG (66.7%) groups as compared to their control counterparts (30.8%). Furthermore, the buffalo of dAI-hCG group had improved (p  0.05) to exhibit stimulatory impact of treatment on luteal profile when compared to control group. In brief, buserelin acetate or hCG treatment on the day of first AI leads to an increase in conception rate; however, an appreciable impact on post-ovulation luteal profile was observed only in hCG-treated Murrah buffalo. © 2016 Blackwell Verlag GmbH.

    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

    Buffalo embryos were produced by hand-made cloning using skin fibroblasts from male and female buffaloes (n = 4 each) as donor cells for examining the effect of sex. Although the rate of blastocyst formation (43.8% ± 1.31% vs. 42.2% ± 1.22%) was similar, the total cell number (333 ± 10.4 vs. 270 ± 10.9) was higher (p female>IVF (in vitro fertilization) blastocysts (p cloned than in IVF blastocysts. This study demonstrates that the epigenetic status, quality, and expression level of several genes but not the developmental competence are affected by the sex of cloned embryos.

    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 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. Copyright © 2011 Elsevier Inc.

    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.

    Full Text Available The efficiency of different doses of rBST in a MOET protocol was verified in buffaloes. The animals received an intravaginal progesterone device (DIB plus 2.0 mg of estradiol benzoate (Ric-BE, i.m. and 0 mg, 250 mg or 500 mg of rBST. Ovarian follicular growth was stimulated by treatment with 200 mg of FSH in decreasing amount (12/12hs. Buffaloes received injections of PGF2α on D6 and on D7. The DIB was removed on D7. On D8, 24 hours after DIB removal, ovulation was induced with GnRH. The follicular emergence and the response to FSH treatment were evaluated by ultrasound on D4 and D8. The artificial insemination (AI was performed 12 and 24 hours after the GnRH administration. The embryonic structures were collected 5.5 days after the first AI. Data were analyzed by ANOVA. No statistical differences were found between groups. The results indicated that rBST, associated to a MOET protocol at the different dosages used, does not to improve the efficiency of the technique in buffalo.

    Mastitis is a highly morbid disease that requires detection at the subclinical stage. Tropical countries like India mainly depend on milch buffaloes for milk. The present study was conducted to investigate whether the trace minerals viz. copper (Cu), iron (Fe), zinc (Zn), cobalt (Co) and manganese (Mn) and enzyme activity of lactate dehydrogenase (LDH), alkaline phosphatase (ALP) and aspartate aminotransferase (AST) in riverine buffalo milk can be used as an indicator of subclinical mastitis (SCM) with the aim of developing suitable diagnostic kit for SCM. Trace elements and enzyme activity in milk were estimated with Atomic absorption Spectrophotometer, GBC 932 plus and biochemical methods, respectively. Somatic cell count (SCC) was done microscopically. The cultural examination revealed Gram positive bacteria as the most prevalent etiological agent. A statistically significant (pmilk containing gram positive bacterial agents only. ALP was found to be elevated in milk infected by both gram positive and negative bacteria. The percent sensitivity, specificity and accuracy, predictive values and likelihood ratios were calculated taking bacterial culture examination and SCC≥2×10(5) cells/ml of milk as the benchmark. Only ALP and Zn, the former being superior, were found to be suitable for diagnosis of SCM irrespective of etiological agents. LDH, Co and Fe can be introduced in the screening programs where Gram positive bacteria are omnipresent. It is recommended that both ALP and Zn be measured together in milk to diagnose buffalo SCM, irrespective of etiology.

    Full Text Available RIG1 and MDA5 have emerged as important intracellular innate pattern recognition receptors that recognize viral RNA and mediate cellular signals controlling Type I interferon (IFN-I response. Buffalo RIG1 and MDA5 genes were investigated to understand the mechanism of receptor induced antiviral response. Sequence analysis revealed that RIG1 and MDA5 maintain a domain arrangement that is common in mammals. Critical binding site residues of the receptors are evolutionary conserved among mammals. Molecular dynamics simulations suggested that RIG1 and MDA5 follow a similar, if not identical, dsRNA binding pattern that has been previously reported in human. Moreover, binding free energy calculation revealed that MDA5 had a greater affinity towards dsRNA compared to RIG1. Constitutive expressions of RLR genes were ubiquitous in different tissues without being specific to immune organs. Poly I:C stimulation induced elevated expressions of IFN-β and IFN-stimulated genes (ISGs through interferon regulatory factors (IRFs mediated pathway in buffalo foetal fibroblast cells. The present study provides crucial insights into the structure and function of RIG1 and MDA5 receptors in buffalo.

    Full Text Available Sinais clínicos e lesões característicos de intoxicação por monensina foram induzidos em búfalos dosados (1 dia com 15, 10, 7,5 e 5mg/kg de monensina. Apenas os búfalos dosados com 2,5 (1 dia e 1 mg/kg (7 dias de monensina não morreram. Os sinais clínicos iniciaram cerca de 6 h após dosagem com monensina e incluíram apatia, anorexia, diarréia, sialorréia, fraqueza muscular, taquicardia, dificuldade locomotora, dispnéia, distensão da jugular, decúbito e morte. As dosagens de creatinina quinase (CK dos búfalos aumentaram acentuadamente após dosagem com monensina. As alterações macroscópicas foram ascite, hidrotórax, hidropericárdio, cardiomegalia, hepatomegalia e áreas pálidas focais no miocárdio e nos músculos esqueléticos. Degeneração e necrose de miofibras foram os principais achados histopatológicos. Por outro lado, nenhuma evidência de doença, nem mesmo alteração nos níveis de CK, foram observados nos bovinos dosados com as mesmas dosagens de monensina, confirmando observações preliminares que esses animais são mais resistentes à monensina que os búfalos.Monensin is widely used as a feed additive to improve performance of livestock; however accidental poisoning by this ionophore compound has been reported in a number of animal species.

    Primordial germ cells (PGCs) are destined to form gametes in vivo, and they can be reprogrammed into pluripotent embryonic germ (EG) cells in vitro. Buffalo PGC have been reported to be reprogrammed into EG-like cells, but the identities of the major signaling pathways and culture media involved in this derivation remain unclear. Here, the effects of basic fibroblast growth factor (bFGF) and downstream signaling pathways on the reprogramming of buffalo PGCs into EG-like cells were investigated. Results showed bFGF to be critical to buffalo PGCs to dedifferentiate into EG-like cells (20 ng/mL is optimal) with many characteristics of pluripotent stem cells, including alkaline phosphatase (AP) activity, expression of pluripotency marker genes such as OCT4, NANOG, SOX2, SSEA-1, CDH1, and TRA-1-81, and the capacity to differentiate into all three embryonic germ layers. After chemically inhibiting pathways or components downstream of bFGF, data showed that inhibition of the PI3K/AKT pathway led to significantly lower EG cell derivation, while inhibition of P53 activity resulted in an efficiency of EG cell derivation comparable to that in the presence of bFGF. These results suggest that the role of bFGF in PGC-derived EG-like cell generation is mainly due to the activation of the PI3K/AKT/P53 pathway, in particular, the inhibition of P53 function.

    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.

    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.

    This study was designed to predict the fertility of water buffalo bull using post-thaw semen quality parameters during peak breeding season. Thirty ejaculates were collected from five bulls with artificial vagina and cryopreserved. At post-thaw, semen was analysed for motility parameters, velocity distribution, kinematics, DNA integrity/fragmentation, viability, mitochondrial transmembrane potential, morphology, plasma membrane and acrosome integrity. Data of 514 inseminations were collected for estimation of in vivo fertility. Pearson's correlation coefficients showed that progressive motility (PM), rapid velocity, average path velocity, straight line velocity, straightness, supravital plasma membrane integrity, viable spermatozoon with intact acrosome or with high mitochondrial activity were correlated with in vivo fertility (r = .81, p fertility was PM. However, combinations of semen quality parameters to predict fertility were better as compared to single parameter. In conclusion, fertility of buffalo bull can be predicted through some of the post-thaw in vitro semen quality tests during peak breeding season. © 2016 Blackwell Verlag GmbH.

    Thirty water buffalo were obtained from a brucellosis-free farm in order to evaluate antibody responses, bacterial clearance and safety to Brucella abortus strain RB51 vaccine in a dose response study. The animals were randomly divided into five treatment groups. Groups I-V received the recommended dose of RB51 vaccine (RD) once, RD twice 4 weeks apart, double RD once, double RD twice 4 weeks apart and saline once, respectively. Antibody responses to RB51 were monitored at 2, 4, 6, 8, 10, 12, 16 18, 22, 24 and 27 post-initial-inoculation weeks (PIW). Clearance of RB51 from the prescapular lymph node was evaluated at 2, 4, 6, 12, 18 and 24 PIW for groups 1, III and V and at 6, 8, 10, 16, 22 and 27 PIW for groups II and IV. To evaluate shedding of the RB51 strain, nasal, conjunctival, vaginal or preputial swabs were taken from all experimental animals at 1, 2, 3, 4, 6, 8 and 12 PIW. Sera taken at all PIW were negative for field strain B. abortus by both the buffered plate agglutination test (BPAT) and competitive enzyme-linked immunosorbent assay (c-ELISA). Antibody responses to RB51 were demonstrated in all vaccinates but not in the controls, up to 12 PIW, by complement fixation test (CFT) and the dot-blot assay with an 83.7% agreement for both tests. Clearance of RB51 occurred between 6 and 12 PIW in group I but less than 2 weeks after booster vaccinations in groups II and IV and between 4 and 6 PIW in group III. RB51 was not recovered at any time from swabs obtained from either RB51-vaccinates or non-vaccinates. The results of this study indicate that serologic responses to RB51 vaccination can be monitored by both CFT and dot-blot assay in water buffalo. Our data also indicates that RB51 vaccination does not interfere with brucellosis sero-surveillance and is safe (no serological and bacteriological evidence of spread to non-vaccinates, no adverse clinical signs or detectable abnormalities on haematology and serum biochemistry) for use in water buffalo.

    The purpose of the present study was to obtain sarcocysts of Sarcocystis buffalonis and Sarcocystis levinei from water buffaloes and characterize the isolates by molecular methods in order to determine whether the two species were genetically different from Sarcocystis hirsuta and Sarcocystis cruzi, respectively, from cattle, which had been characterized before. About 35 macroscopically visible (3-4 × 1-2 mm) and 20 barely visible (1-3 × 0.2 mm) sarcocysts were excised from the esophagus of 18 naturally infected and freshly slaughtered adult water buffaloes at three slaughterhouses in Egypt. Genomic DNA was extracted from the sarcocysts, and all isolates were first characterized at the mitochondrial cytochrome c oxidase subunit I gene (cox1) gene through PCR amplification and direct sequencing. Selected isolates were subsequently further characterized at the 18S and 28S ribosomal (r) RNA genes and the internal transcribed spacer 1 (ITS1) region of the nuclear rDNA unit by direct sequencing or cloning. Only six of the isolated macroscopic sarcocysts belonged to S. buffalonis, whereas the others belonged to Sarcocystis fusiformis. Twelve of the smaller cysts belonged to S. levinei and seven to Sarcocystis sinensis. The characterization of the sarcocysts of S. sinensis and some of the sarcocysts of S. fusiformis have been reported before. Fifteen additional sarcocyst isolates of S. fusiformis were characterized at cox1 in the present study and found to be identical or closely similar to previous isolates. At cox1, the sequence identity between the six isolates of S. buffalonis was 99.8-100 % (two haplotypes), whereas the identity between the 12 isolates of S. levinei was 99.0-100 % (10 haplotypes). The identity between cox1 sequences of S. buffalonis and S. hirsuta (n = 56) was 92.9-93.6 % (on average 93.4 %), and the identity between cox1 sequences of S. levinei and S. cruzi (n = 22) was 92.9-94.0 % (on average 93.5 %).

    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

    Full Text Available Mature spermatozoa have highly condensed DNA that is essentially silent both transcriptionally and translationally. Therefore, post translational modifications are very important for regulating sperm motility, morphology, and for male fertility in general. Protein sumoylation was recently demonstrated in human and rodent spermatozoa, with potential consequences for sperm motility and DNA integrity. We examined the expression and localization of small ubiquitin-related modifier-1 (SUMO-1 in the sperm of water buffalo (Bubalus bubalis using immunofluorescence analysis. We confirmed the expression of SUMO-1 in the acrosome. We further found that SUMO-1 was lost if the acrosome reaction was induced by calcium ionophore A23187. Proteins modified or conjugated by SUMO-1 in water buffalo sperm were pulled down and analyzed by mass spectrometry. Sixty proteins were identified, including proteins important for sperm morphology and motility, such as relaxin receptors and cytoskeletal proteins, including tubulin chains, actins, and dyneins. Forty-six proteins were predicted as potential sumoylation targets. The expression of SUMO-1 in the acrosome region of water buffalo sperm and the identification of potentially SUMOylated proteins important for sperm function implicates sumoylation as a crucial PTM related to sperm function.

    This study investigates for the first time mRNA pregnancy-associated glycoprotein 2 (PAG-2) expression in blood cells during early pregnancy in water buffalo. The PAGs constitute a large family of glycoproteins expressed in the outer epithelial layer of the placenta in eutherian species. All PAGs are not concomitantly expressed throughout pregnancy; some of them are expressed in the earlier phases, whereas others appear later and are expressed over a shorter period. Twenty-one lactating buffaloes were analyzed-17 females were synchronized with PRID and artificially inseminated (AI), whereas four females were synchronized but not inseminated (control group). Blood was collected at Days 0, 18, 28, 40, and 75 from AI (AI = Day 0). Expression of PAG-2 mRNA in blood samples was measured with real-time polymerase chain reaction. Pregnancy diagnosis was performed on Day 28 (D28) and Day 40 (D40) after AI by ultrasonography (US) and by PAG-1 RIA method. The females diagnosed pregnant at D28 and confirmed pregnant at D40 were defined as D28(+)D40(+) group; the females diagnosed pregnant at D28 but not confirmed pregnant at D40 were defined as D28(+)D40(-) group; and the females that were diagnosed as nonpregnant on either days were defined as D28(-)D40(-) group. PAG-2 mRNA at Day 0 was not observed in any groups. The D28(+)D40(+) group showed the highest expression, starting on Day 18 and increasing progressively up to Day 75. PAG-2 mRNA was also expressed on Day 18 in both D28(+)D40(-) and D28(-)D40(-) groups, but their levels were lower than those of D28(+)D40(+) group and almost constant over time. PAG-2 mRNA was never detected in the control group. The significant difference in the expression of PAG-2 mRNA between the D28(+)D40(+) group and the D28(-)D40(-) group, starting from Day 18, suggests that these animals might have conceived, but have experienced early embryonic loss; therefore, the PAG-2 mRNA was still present in blood circulation although at lower levels

    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 Ca2+ channels blocker) and NNC55-0396 (T-type Ca2+ 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 Ca2+ 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) Ca2+-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.

    We evaluated the suitability of 10 candidate internal control genes (ICGs), belonging to different functional classes, namely ACTB, EEF1A1, GAPDH, HPRT1, HMBS, RPS15, RPS18, RPS23, SDHA, and UBC for normalizing the real-time quantitative polymerase chain reaction (qPCR) data of blastocyst-stage buffalo embryos produced by hand-made cloning and in vitro fertilization (IVF). Total RNA was isolated from three pools, each of cloned and IVF blastocysts (n = 50/pool) for cDNA synthesis. Two different statistical algorithms geNorm and NormFinder were used for evaluating the stability of these genes. Based on gene stability measure (M value) and pairwise variation (V value), calculated by geNorm analysis, the most stable ICGs were RPS15, HPRT1, and ACTB for cloned blastocysts, HMBS, UBC, and HPRT1 for IVF blastocysts and RPS15, GAPDH, and HPRT1 for both the embryo types analyzed together. RPS18 was the least stable gene for both cloned and IVF blastocysts. Following NormFinder analysis, the order of stability was RPS15 = HPRT1>GAPDH for cloned blastocysts, HMBS = UBC>RPS23 for IVF blastocysts, and HPRT1>GAPDH>RPS15 for cloned and IVF blastocysts together. These results suggest that despite overlapping of the three most stable ICGs between cloned and IVF blastocysts, the panel of ICGs selected for normalization of qPCR data of cloned and IVF blastocyst-stage embryos should be different.

    Antigenic components of buffalo (Bos bubalis) serum, which were also components of buffalo colostrum, seminal plasma, milk whey, saliva, and tears, were investigated by the ager gel diffusion test and immunoelectrophoresis. Immunoglobulins of buffalo serum were identified by immunoelectrophoresis employing rabbit-anti-buffalo serum and rabbit-anti-buffalo gamma-globulin. Based on immunoelectrophoretic patterns immunoglobulin G (IgG), IgGA, and IgM were detected both in the serum and colostrum of buffaloes. Tears contained both IgG and IgM. Cross-reactions of buffalo serum with seminal plasma, saliva, and milk whey were observed only in the IgG region. By polyacrylamide gel electrophoresis, lipoprotein (5.2% +/- 0.41), IgM (11.4% +/- 3.1), IgG (9.4% +/- 0.98), haptoglobin 21.8% +/- 3.73), transferrin (10.4% +/- 2.15), ceruloplasmin (7.8% +/- 1.3), postalbumin (20.8% +/- 2.09), and albumin (13.7% +/- 0.75) were identified provisionally.

    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.

    Regucalcin (RGN), a calcium regulating protein having anti-prolific, antiapoptotic functions, plays important part in the biosynthesis of ascorbic acid. It is a highly conserved protein that has been reported from many tissue types of various vertebrate species. Employing its effect of regulating enzyme activities through reaction with sulfhydryl group (-SH) and calcium, structural level study believed to offer a better understanding of binding properties and regulatory mechanisms of RGN, was performed. Using sample from testis of Bubalus bubalis, amplification of regucalcin (RGN) gene was subjected to characterization by performing digestion using different restriction endonucleases (RE). Alongside, cDNA was cloned into pPICZαC vector and transformed in DH5α host for custom sequencing. To get a better insight of its structural characteristics, three dimensional (3D) structure of protein sequence was generated using in silico molecular modelling approach. The full trajectory analysis of structure was achieved by the Molecular Dynamics (MD) that explains the stability, flexibility and robustness of protein during simulation in a time of 50ns. Molecular docking against 1,5-anhydrosorbitol was performed for functional characterization of RGN. Preliminary screening of amplified products on Agarose gel showed expected size of ~893 bp of PCR product corresponding to RGN. Following sequencing, BLASTp search of the target sequence revealed that it shares 91% similarity score with human senescence marker protein-30 (pdb id: 3G4E). Molecular docking of 1,5-anhydrosorbitol reveals information regarding important binding site residues of RGN. 1,5-anhydrosorbitol was found to interact with binding free energy of - 6.01 Kcal/mol. RMSD calculation of subunits A, B and D-F might be responsible for functional and conserved regions of modeled protein. Three dimensional structure of RGN was generated and its interactions with 1,5- anhydrosorbitol, demonstrates the role of key

    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.

    Thirty water buffalo, obtained from a brucellosis-free farm, were used to evaluate cell-mediated immune responses and bacterial clearance in response to vaccination with Brucella abortus strain RB51 (RB51) in a dose-response study. The animals were randomly divided into five treatment groups. Groups I--V received the recommended dose (RD) of RB51 vaccine once, RD twice 4 weeks apart, double RD once, double RD twice 4 weeks apart and saline once, respectively. Cell-mediated immune response to RB51 was assessed by the histological examination of haematoxylin and eosin (H&E) stained sections of lymph nodes draining the sites of inoculation and by comparison of stimulation indices (SI) derived from gamma interferon (IFN-gamma) assay. A mixture of cytoplasmic proteins from B. melitensis B115 (brucellergene) was used as a specific antigenic stimulus to peripheral blood mononuclear cells (PBMC) and lymph node mononuclear cells (LNMC) up to 22 post-initial-inoculation week (PIW). Supernatants harvested at 18-24h after the in vitro antigenic stimulus were assayed for their IFN-gamma content by using a commercial sandwich enzyme-linked immunosorbent assay (ELISA) kit. Clearance of RB51 was assessed by the sequential immunohistochemical examination of sections of draining lymph nodes post-inoculation. There was no observable expansion of the deep cortex of lymph nodes on H&E sections indicating poor T-cell stimulation. All group V (control) water buffalo PBMC ELISA values were negative (SIRB51 occurred between 4 and 6 PIW in treatment groups I and III and between 6 and 12 PIW in groups II and IV. RB51 was not detected in any of the control animals at sampling intervals post-inoculation.

    The lymph system of three amphistome parasites from buffaloes, Gigantocotyle explanatum, Gastrothylax crumenifer and Srivastavaia indica was studied using light microscope histochemistry and electron microscopy. In each case the system comprised a single pair of main longitudinal vessels which gave rise to numerous sub-dividing lateral branches. Although the finer lymph channels associated with most internal systems, they did not penetrate the basement membrane of any organ. The lymph vessels were delimited by a unit membrane and separated from adjacent cells by interstitial material. The lymph fluid consisted of an amorphous proteinaceous, lipid-rich matrix, containing naked nuclei and granules of various sizes. Complexes of endoplasmic reticulum were frequently associated with the nuclei. No distinct Golgi bodies or mitochondria were evident. The granules noted throughout the lymph morphologically resembled autophagosomes and lysosomes. Autophagy within the lymph system presumably mobilizes amino acids for subsequent transport to tissues undergoing active protein synthesis. The lymph channels displayed an intimate relationship with the general parenchyma. In particular, numerous protrusions of lymph occurred into the cytoplasm of certain specialized parenchymal cells surrounding the pharynx. Within these 'juxtapharyngeal' cells autophagic degradation of sequestered lymph cytoplasm apparently occurred. In the three species of amphistome studied, the lymph system appears to function in storage and mobilization of amino acids and possibly lipids. It may also serve to distribute other small molecules throughout the body. The detection of haemoglobin in the lymph system of G. crumenifer and S. indica, but not in Gigantocotyle explanatum, suggests a further role in oxygen storage and transport.

    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.

    Insulin-like growth factor binding protein-5 (IGFBP-5) is a key molecule in mammary gland development, which facilitates the removal of mammary epithelial cells (MECs) by apoptosis that takes place during remodeling of the mammary gland during involution. IGFBP-5 binds with IGFs for their bioavailability. IGFBP-5 has been reported to perform pleiotropic roles such as cellular apoptosis, proliferation and differentiation. To understand the role of IGFBP-5 during lactation and clinical mastitis, expression profiling of IGFBP-5 at the protein level was performed in both indigenous cows (Bos indicus) and buffaloes (Bubalus bubalis) belonging to two different breeds - Sahiwal cows and Murrah buffaloes. Reverse-transcriptase PCR (RT-PCR) of IGFBP-5 mRNA confirmed its expression in milk somatic cells and MECs of Sahiwal cows. ELISA was performed for quantitative measurement of IGFBP-5 concentrations in milk during different days (0, 50, 100, 150, 200, 250 and 300) of lactation, during the involution period and in animals exhibiting short lactation and clinical mastitis. The highest concentration of IGFBP-5 in milk was observed during the involution period followed by colostrum, late and early lactation, respectively, in both cattle and buffaloes. No significant difference in the concentration of IGFBP-5 was observed during the first 150 days of lactation between cows and buffaloes. However, higher concentration of IGFBP-5 was observed in cows during late lactation (200 to 300 days) in comparison with buffaloes. To validate the ELISA data, quantitative real-time PCR was performed in MECs of Sahiwal cows. The relative mRNA abundance of IGFBP-5 was found to be significantly (Plactation in case of Sahiwal cows. Highest mRNA expression of IGFBP-5 was observed around 300 days of lactation followed by 200 and 250 days (Plactation in ELISA. Animals having history of short lactation length (short lactating animals) showed higher levels of IGFBP-5 expression (at protein level) in

    Full Text Available River buffalo (Bubalus bubalis bubalis with a population over 135 million heads is an important livestock. Interleukin 8 (IL-8 is a member of the chemokine family and is an important chemoattractant for neutrophils associated with a wide variety of inflammatory diseases such as endometritis. Tissue samples from the mammary gland, uterus and ovary were obtained from river buffalo (Mediterranean type with and without endometritis. Bacteriological examination showed the presence of both gram positive and negative in all buffalo with endometritis. RNA extraction and complementary DNA (cDNA synthesis were conducted from all tissues. Specific primer for IL8 full coding regions was designed using known cDNA sequences of Bubalus bubalis, Genbank accession number AY952930.1. IL-8 gene expression was investigated in buffalo tissues. Expression of IL-8 in buffalo with endometritis was found to increase significantly over buffalo without endometritis only in the uterus (P = 0.0159. PCR products from uterus tissues (target organs of buffalo with and without endometritis, were purified and sequenced. No polymorphic sites were detected in the investigated samples. IL-8 cDNA nucleotide sequences of buffalo with and without endometritis were 100% identical (accession number JX413057. Buffalo IL8 cDNAs were compared with corresponding sequences of member of subfamily Bovinae (buffalo and cattle and subfamily Caprinae (sheep and goat. IL-8 species specific differences were identified.

    Milk samples from 206 apparently healthy buffaloes of marginal farmers maintained under the prevailing field conditions were screened for Subclinical Mastitis (SCM) to determine its prevalence and etiology by White Side Test (WST), California Mastitis Test (CMT), Somatic Cell Count (SCC) and Bacteriological examination. 26.20% of animals were positive for SCM in SCC and bacteriological examination. Prevalence in graded Murrah buffaloes were found to be higher compared to graded Surti and Non-descript breeds. The prevalence of SCM was highest in above 6th stage of lactation. Single quarter infection (51.85%) was more common compared to multiple quarter infection. Hind (83.34%) and left side (57.41%) quarters were more prone to SCM. The indirect tests such as WST and CMT were found to be closely agreement with SCC and bacteriological examination. Due to their efficacious, easy to perform and interpret, these tests can effectively be employed to detect SCM under field conditions. Somatic cell count of = 3,00,000/mL of milk was regarded as the upper limit for normal buffaloes. The SCC of = 3,00,000/mL of milk with positive bacterial growth were used to diagnose SCM in the present study. Staphylococcus sp. 25 (46.30%) was the most common pathogens isolated from SCM followed by Streptococcus sp. 11 (20.37%) and E. coli 06 (11.11%) of the 54 bacterial isolates. Monobacterial and mixed bacterial infections were observed in 47 (87.04%) and 7 (12.96%) cases respectively.

    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

    The cytochrome b genes of all living species of Bubalus, including the river type and the swamp type of domestic buffaloes (Bubalus bubalis), were sequenced to clarify their phylogenetic relationships. These sequences were compared together with the African buffalo (Syncerus caffer) and banteng (Bos javanicus) sequences as an outgroup. Phylogenetic trees of Bubalus species based on the DNA sequences of the cytochrome b gene demonstrated that the tamaraw (Bubalus mindorensis), endemic to the Philippines, could be classified into the subgenus Bubalus, not the subgenus Anoa. The divergence time between the lowland anoa (B. depressicornis) and the mountain anoa (B. quarlesi) was estimated at approximately 2.0 million years (Myr), which is almost the same as the coalescence time for the Bubalus sequences. This large genetic distance supports the idea that the lowland anoa and the mountain anoa are different species. An unexpectedly large genetic distance between the river and the swamp type of domestic buffaloes suggests a divergence time of about 1.7 Myr, while the swamp type was noticed to have the closest relationship with the tamaraw (1.5 Myr). This result implies that the two types of domestic buffaloes have differentiated at the full species level.

    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 ABSTRACT In this study, we determined the amount of carnosine and anserine in water buffalo meat without hanging treatment and the free amino acid profile by using amino acid analyser with post-column ninhydrin derivatization procedure. The main free amino acids present in samples were glutamic acid (>60 mg/100 g, followed by alanine, glycine, and arginine. Other protein amino acids were detected in minor amounts (less than 2 mg/100 g. Among the non-protein amine-containing compounds, taurine and urea were the most abundant. The analysis showed that 50% of the total free amino acids was represented by dipeptides carnosine (average ~130.3 mg/100 g and anserine (average ~17.9 mg/100 g. Thus, this study for the first time reports the free amino acids profile of water buffalo meat and the content of carnosine and anserine, potentially involved in the darkening meat process and their ratio, that could be used to estimate the water buffalo meat portion in mixed meat products.

    Full Text Available In the present report the biochemical polymorphism of hemoglobins in 96 Indian buffaloes from different breed groups of Murrah, Jafarabadi and Mediterranean races reared in the experimental farm Lageado - UNESP - Botucatu, State of São Paulo was studied. Hemoglobins variants were identified through agarstarch gel electrophoresis, in discontinuous buffer system, pH 8.6. Animals showing one fast band (A, were considered AA (4.4%; buffaloes with two bands (A, and A2 were considered AB (31.87% when A2 was weak and BB (31.87%, when A2 was strong. A third band was detected, named N. Phenotypes with three bands with the respective frequencies: ABN (3.3% and BBN (30.77%. Densitometric analyses and the lack of AAN phenotype drove us to conclude that, in some way, the mutant (3 chains synthesis that originated N band was related probably to a" allele. Probably, the high frequency of N band was due to the intensive use of few breeders.

    Full Text Available Aim: Evaluation of combined effect of fenvalerate and nitrate on biochemical parameters in buffalo calves. Materials and Methods: Sixteen male buffalo calves were divided into four groups of four calves each. Group I receiving no treatment served as the control. Group II and III animals were orally administered with fenvalerate (1.0 mg/kg/day and sodium nitrate (20 mg/kg/day, respectively, for 21 consecutive days and were kept as positive control. Group IV animals were co-administered with fenvalerate and sodium nitrate at the above dose rates for 21 consecutive days. Biochemical parameters including Aspartate aminotransferase (AST, Alkaline phosphatase (ALP, Gamma-glutamyl transpeptidase (GGT, Lactate dehydrogenase (LDH, Glucose, Total protein, Albumin, Cholesterol, Blood urea nitrogen (BUN and Creatinine were determined on 0, 3, 7, 10, 14, 17 and 21 day of treatment. Estimation of these parameters was also done on 7th day of post-treatment period. Results: Co-administration of fenvalerate and sodium nitrate produced significant increase in the plasma levels of AST, ALP, GGT, LDH, glucose, BUN, cholesterol and creatinine while significant decrease in the plasma levels of total proteins was observed. No significant alteration was observed in albumin levels. Extent of organ damage as evidenced by biochemical alterations was more pronounced in calves exposed to combination of fenvalerate and sodium nitrate as compared to their individual exposures. Conclusion: Fenvalerate and sodium nitrate co-administration potentiates the toxicological injury produced, in comparison to their individual exposure.

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.

    Understanding of biological impact of proteome profile on meat quality is vital for developing different approaches to improve meat quality. Present study was conducted to unravel the differences in biochemical, ultrastructural and proteome profile of longissimus dorsi muscle between buffaloes (Bubalus bubalis) of different age groups (young v. old). Higher (Pmuscle fibre diameter, and Warner-Bratzler shear force (WBSF) values was observed in old buffalo meat relative to meat from young buffaloes. Scanning electron microscopy photographs revealed reduced fibre size with increased inter-myofibrillar space in young compared with old buffalo meat. Transmission electron microscopy results revealed longer sarcomeres in young buffalo meat relative to meat from old buffaloes. Proteomic characterization using two-dimensional gel electrophoresis (2DE) found 93 differentially expressed proteins between old and young buffalo meat. Proteome analysis using 2DE revealed 191 and 95 differentially expressed protein spots after 6 days of ageing in young and old buffalo meat, respectively. The matrix assisted laser desorption ionization time-of flight/time-of flight mass spectrometry (MALDI-TOF/TOF MS) analysis of selected gel spots helped in identifying molecular markers of tenderness mainly consisting of structural proteins. Protein biomarkers identified in the present study have the potential to differentiate meat from young and old buffaloes and pave the way for optimizing strategies for improved buffalo meat quality.

    This study was conducted to identify and analyse the expression of gametogenesis-associated genes and proteins in foetal and adult buffalo gonads of both the sexes. Relative quantification of the genes was determined by qPCR and Western blotting. Immunohistochemistry was also performed for various gametogenesis-associated proteins in foetal and adult gonads of both the sexes. We observed significantly (p gametogenesis-associated proteins in ovarian follicles and seminiferous tubules of testes, while the surrounding somatic tissues were devoid of these proteins. The study gives an understanding of the sequential and temporal events of gene expression as well as mRNA translation during male and female gametogenesis. It could also be concluded that follicles and seminiferous tubules are the functional units of the female and male gonads, respectively, and their function could be enhanced by appropriate chemical and genetic intervention of the somatic tissue immediately surrounding them. This assumes importance in the context that buffalo attains sexual maturity at an older age of 2-3 years and have smaller ovaries with lesser number of primordial follicles in comparison with cattle, which is suggested to be the main reason of their poor breeding performance. © 2015 Blackwell Verlag GmbH.

    Full Text Available Abstract Background The water buffalo- Bubalus bubalis holds tremendous potential in livestock sector in many Asian countries, particularly India. The origin, domestication and genetic structure of the Indian river buffalo are poorly understood. Therefore, to understand the relationship among the maternal lineages of Indian river buffalo breeds and their domestication process, we analysed mitochondrial D-loop region of 217 animals representing eight breeds from eight different locations in India along with published sequences of Mediterranean buffalo. Results The maximum parsimony tree showed one major clade with six internal branches. Reduced median network revealed expansion from more than one set of haplotypes indicating complex domestication events for this species. In addition, we found several singleton haplotypes. Using rho statistics, we obtained a time estimate of 6300 years BP for the expansion of one set of hapltoypes of the Indian domestic buffalo. A few breed specific branches in the network indicated an ancient time depth of differentiation of some of the maternal lineages of river buffalo breeds. The multidimensional display of breed pairwise FST values showed significant breed differentiation. Conclusion Present day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from the wild populations after the initial domestication events. Our data are consistent with the available archaeological information in supporting the proposition that the river buffalo was likely to be domesticated in the Western region of the Indian subcontinent, specifically the present day breeding tracts of the Mehsana, Surati and Pandharpuri breeds.

    The aim of the present study was to determine the optimal phase of the follicular wave to perform ovum pickup (OPU) for in vitro embryo production (IVEP) in various genetic groups. For this purpose, 27 heifers-nine Bos taurus (Holstein), nine Bos indicus (Nelore), and nine Bubalus bubalis (Mediterranean)-were maintained under the same nutritional, management, and environmental conditions. Heifers within each genetic group were submitted to six consecutive OPU trials with 14-day intersession intervals, at three different phases of the pharmacologically synchronized follicular wave (Day 1, 3, or 5 after follicular wave emergence), in a 3 × 3 crossover design. When OPU was performed at different phases of the pharmacologically synchronized follicular wave (Day 1, 3, or 5), no differences were found in the percent of oocytes recovered (70.5 ± 3.1%, 75.0 ± 3.1%, 76.0 ± 3.2%, respectively; P = 0.41) or blastocyst production rates (19.4 ± 2.9%, 16.6 ± 2.9%, 15.9 ± 2.6%, respectively; P = 0.36). Comparing genetic groups, B indicus showed a higher blastocyst rate (28.3(a) ± 2.8%; P taurus and B bubalis (14.1(b) ± 2.9% and 10.2(b) ± 2.0%, respectively). However, only B indicus heifers showed a variation in the number of visualized follicles and the total and viable oocytes along consecutive OPU sessions. In conclusion, different phases of the pharmacologically synchronized ovarian follicular wave did not affect OPU-IVEP in B indicus, B taurus, and B bubalis heifers. Additionally, B indicus heifers showed greater OPU-IVEP efficiency than did the other genetic groups, under the same management conditions. Copyright © 2015 Elsevier Inc. All rights reserved.

    A retrospective analysis using records of lactating Bulgarian Murrah buffaloes subjected to the California Mastitis Test in a herd in Nueva Ecija, Philippines was done to determine the prevalence of subclinical mastitis (SCM) and to identify risk factors that may influence its occurrence and recurrence. Results showed that SCM prevalence was 42.76%, whereas its recurrence was 75.03%. Age and lactation length influenced the occurrence of SCM. In contrast to the conclusions for dairy cows, younger buffalo cows were more susceptible compared with those at least 6 yr old. Dams younger than 3 yr have a 76% probability, whereas those age 3 yr have an 82% probability of having SCM. Copyright © 2012 American Dairy Science Association. Published by Elsevier Inc.

    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.

    Full Text Available The effects of ionophores (monensin and probiotic (Saccharomyces cerevisiae + selenium + chromium in diets with 80% forage were evaluated on the digestibility of nutrients. Three buffaloes, Murrah (Bubalus bubalis and three cattle, Holstein (Bos taurus, with an average weight of 520 ± 30 kg and 480 ± 182 kg, respectively, with rumen cannula, over experimental design with two 3 x 3 Latin squares in a 3 x 2 factorial arrangement, with the absence or presence of additives: ionophore or probiotic and two species, were used. The internal flow indicator of fecal dry matter (DM was the acid insoluble ash. DM, crude protein (CP and neutral detergent fiber (NDF ruminal degradability of Tifton 85 hay was conducted for cattle and buffaloes. A diet containing probiotics had higher dry matter and organic matter digestibility in buffalo and cattle, indicating a good performance in bulky diets. The potential and effective dry matter degradability in diet with probiotic in buffaloes, were smaller than diet with ionophore, suggesting that there was a better digestion of nutrients in the intestine of these animals. The potential and effective degradability of neutral detergent fiber and crude protein in the diet containing ionophores were superior than diet containing probiotic. Buffaloes showed higher capacity of dry matter and fiber digestion than cattle.

    Interspecies hybridization of bovids occurs between domestic cattle and at least three other species; American bison (Bison bison), yak (Bos grunniens) and banteng (Bos banteng). Birth of a cattlexbuffalo (Bubalus bubalis) hybrid has reportedly occurred in Russia and in China, but these reports were not authenticated. Such hybrids could be important in improving livestock production and management of diseases that impede production in tropical Africa. This study investigated hybridization between cattle and its closest African wild bovid relative, the African buffalo (Syncerus caffer caffer). In an attempt to produce cattlexbuffalo hybrid embryos in vitro, matured cattle oocytes were subjected to a standard in vitro fertilization (IVF) procedure with either homologous cattle (n=1166 oocytes) or heterologous African buffalo (n=1202 oocytes) frozen-thawed epididymal sperm. After IVF, 67.2% of the oocytes inseminated with the homologous cattle sperm cleaved. In contrast, fertilization with buffalo sperm resulted in only a 4.6% cleavage rate. The cleavage intervals were also slower in hybrid embryos than in the IVF-derived cattle embryos. Of the cleaved homologous cattle embryos 52.2% progressed to the morula stage compared with 12.7% for the buffalo hybrid embryos. No hybrid embryos developed beyond the early morula stage, while 40.1% of the cleaved cattlexcattle embryos developed to the blastocyst stage. Transfer of buffalo hybrid IVF embryos to domestic cattle surrogates resulted in no pregnancies at 60 days post-transfer. This study indicates that interspecies fertilization of cattle oocytes with African buffalo epididymal sperm can occur in vitro, and that a barrier to hybridization occurs in the early stages of embryonic development. Chromosomal disparity is likely the cause of the fertilization abnormalities, abnormal development and subsequent arrest impairing the formation of hybrid embryos beyond the early morula stage.

    Full Text Available The objective of this study was to evaluate the effect of reducing sperm numbers per insemination dose on fertility of cryopreserved buffalo bull semen. For this purpose, semen was collected at weekly intervals from a Nili-Ravi buffalo bull (Bubalus bubalis using an artificial vagina in two batches. The ejaculates were split-sampled and diluted at 37°C with tris-citric acid extender having 15x106 or 30x106 motile spermatozoa/0.5 ml. After dilution, the semen was cooled to 4C, equilibrated for 4 hours, packaged in 0.5 ml straws and frozen in programmable cell freezer. Fertility test based on 75-days first service pregnancy rate was determined under field conditions. A total of 500 buffaloes were inseminated with frozen semen and out of these 431 could be followed, 209 for semen straws packaged with 15x106 spermatozoa/straw and 222 for doses filled with 30x106 spermatozoa/straw. The inseminations were performed in two batches and each batch was spread over a period of three months. The fertility rate for sperm concentration of 15x106 spermatozoa/0.5 ml vs. 30x106 spermatozoa/0.5 ml (49.28 vs. 56.75% was similar (P>0.05. The fertility rates were also similar (P>0.05 in the first and second batch of inseminations performed with 15x106 or 30x106 spermatozoa/0.5 ml straw of cryopreserved semen. In conclusion, reduction of sperm number from 30x106 to 15x106 spermatozoa/0.5 ml dose of insemination did not affect fertility of cryopreserved buffalo bull semen.

    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 (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 Mastitis set apart as clinical and sub clinical is a disease complex of dairy cattle, with sub clinical being the most important economically. Of late, laboratories showed interest in developing biochemical markers to diagnose sub clinical mastitis (SCM in herds. Many workers reported noteworthy alternation of acute phase proteins (APPs and nitric oxide, (measured as nitrate+nitrite = NOx in milk due to intra-mammary inflammation. But, the literature on validation of these parameters as indicators of SCM, particularly in riverine milch buffalo (Bubalus bubalis milk is inadequate. Hence, the present study focused on comparing several APPs viz. α1- anti trypsin, α1- acid glycoprotein, fibrinogen and NOx as indicators of SCM in buffalo milk. These components in milk were estimated using standardized analytical protocols. Somatic cell count (SCC was done microscopically. Microbial culture was done on 5% ovine blood agar. Of the 776 buffaloes (3,096 quarters sampled, only 347 buffaloes comprising 496 quarters were found positive for SCM i.e. milk culture showed growth in blood agar with SCC≥2×105 cells/ml of milk. The cultural examination revealed Gram positive bacteria as the most prevalent etiological agent. It was observed that α1- anti trypsin and NOx had a highly significant (p<0.01 increase in SCM milk, whereas, the increase of α1- acid glycoprotein in infected milk was significant (p<0.05. Fibrinogen was below detection level in both healthy and SCM milk. The percent sensitivity, specificity and accuracy, predictive values and likelihood ratios were calculated taking bacterial culture examination and SCC≥2×105 cells/ml of milk as the benchmark. Udder profile correlation coefficient was also used. Allowing for statistical and epidemiological analysis, it was concluded that α1- anti trypsin indicates SCM irrespective of etiology, whereas α1- acid glycoprotein better diagnosed SCM caused by gram positive bacteria. NOx did not prove to

    Full Text Available Four Thai - rumen fistulated male swamp buffaloes (Bubalus bubalis, about four years old with 400±20 kg liveweight, were randomly assigned according to a 4×4 Latin square design to receive dietary treatments. The treatments were: ground corn cob (GCC replacement for cassava chip (CC in concentrate at 0% (T1; GCC replacement at 33% (T2; GCC replacement at 67% (T3; and GCC replacement at 100% (T4, respectively. During the experiment, concentrate was offered at 0.5% BW while 5% urea-treated rice straw was given at ad libitum. The result revealed that there was no effect of GCC replacement on DMI among treatments. In addition, digestibilities of DM, OM and CP were not different while aNDF linearly increased with an increasing level of GCC replacement. However, GCC replacement did not affect rumen fermentation such as ruminal pH, NH3-N and VFA concentration; except C3 proportion which was the highest at 33% replacement while the lowest was at 100% replacement. All replacements of GCC resulted in similar protozoal and bacterial populations and microbial protein synthesis (MPS. Purine derivatives (PD concentration in urine and PD to creatinine (PDC index were varied with time of urination and among treatments at 0 to 8 and 8 to 16 h post feeding and higher values were shown among the GCC replacement groups. However at 16 to 24 h-post feeding, it was untraceable. In addition, creatinine concentration was similar among all treatments at every sampling time. Based on the above results, GCC can be used as an energy source for swamp buffalo fed with rice straw. Spot sampling of urine can be used for purine derivatives determination.

    2017-02-01

    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.

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 conducted to evaluate the utilisation of the residual feed intake (RFI) as a feed efficiency selection tool and its relationship with methane emissions. Eighteen Murrah buffalo (Bubalus bubalis) heifers were fed ad libitum with total mixed ration (TMR) for 120 days. Based on linear regression models involving dry matter intake (DMI), average daily gain (ADG) and mid-test metabolic body size (MBW0.75 ), heifers were assigned into low and high RFI groups. The RFI varied from -0.09 to +0.12 kg DM/day with average RFI of -0.05 and 0.05 kg DM/day in low and high RFI heifers respectively. Low RFI heifers ate 11.6% less DM each day, yet average daily gain (ADG) and feed utilisation were comparable among low and high RFI groups. Low RFI heifers required significantly (p energy for maintenance (MEm) compared to high RFI heifers. Apparent nutrient digestibility showed non-significant difference (p > .05) among low and high RFI groups. Although the nitrogen balance was similar among heifers of low and high RFI groups, nitrogen metabolism was significantly higher (p > .05) in high RFI heifers. Comparison of data from heifers exhibiting the low (n = 9) and high (n = 9) RFI showed that the low RFI heifers have lower enteric methane production and methane losses than high RFI heifers. In conclusion, results of this study revealed that selection of more efficient buffalo heifers has multiple benefits, such as decreased feed intake and less emission of methane. © 2017 Blackwell Verlag GmbH.

As membranas fetais foram analisadas macroscópica e microscopicamente (luz e microscopia eletrônica de transmissão. O córion possui uma camada simples de células circulares, com núcleos de forma esférica, denominadas trofobláticas; há outro tipo celular, as células trofoblásticas gigantes, com dois ou mais núcleos. Ambas possuem uma grande quantidade de vesículas no citoplasma e retículo endoplasmático à microscopia de transmissão. O alantóide possui vasos preenchidos com eritrócitos, e contêm células alongadas, que formam um epitélio estratificado simples. O âmnion é uma membrana transparente, ou esbranquiçada; constituído por epitélio estratificado simples. A diferença principal entre o alantóide e o âmnion é que o último é avascular. O saco vitelínico é uma membrana opaca que desaparece durante a gestação; é a única membrana que não está em contato com as outras e apresenta três tipos diferentes de células que dão forma a três camadas distintas (endoderma, mesotélio, mesênquima.The aim of the study was to characterize the fetal membranes in buffalo cows (Bubalus bubalis, Linnaeus 1758 in the first 3 months of the gestation.

    Comparative FISH-mapping among Y chromosomes of cattle (Bos taurus, 2n = 60, BTA, submetacentric Y chromosome), zebu (Bos indicus, 2n = 60, BIN, acrocentric Y chromosome but with visible small p-arms), river buffalo (Bubalus bubalis, 2n = 50, BBU, acrocentric Y chromosome), sheep (Ovis aries, 2n = 54, OAR, small metacentric Y chromosome) and goat (Capra hircus, 2n = 60, CHI, Y-chromosome as in sheep) was performed to extend the existing cytogenetic maps and improve the understanding of karyotype evolution of these small chromosomes in bovids. C- and R-banding comparison were also performed and both bovine and caprine BAC clones containing the SRY, ZFY, UMN0504, UMN0301, UMN0304 and DYZ10 loci in cattle and DXYS3 and SLC25A6 in goat were hybridized on R-banded chromosomes by FISH. The main results were the following: (a) Y-chromosomes of all species show a typical distal positive C-band which seems to be located at the same region of the typical distal R-band positive; (b) the PAR is located at the telomeres but close to both R-band positive and ZFY in all species; (c) ZFY is located opposite SRYand on different arms of BTA, BIN, OAR/CHI Y chromosomes and distal (but centromeric to ZFY) in BBU-Y; (d) BTA-Y and BIN-Y differ as a result of a centromere transposition or pericentric inversion since they retain the same gene order along their distal chromosome regions and have chromosome arms of different size; (e) BTA-Y and BBU-Y differ in a pericentric inversion with a concomitant loss or gain of heterochromatin; (f) OAR/CHI-Y differs from BBU-Y for a pericentric inversion with a major loss of heterochromatin and from BTA and BIN for a centromere transposition followed by the loss of heterochromatin.

    The aims of this study were to assess the efficacy of alphacypermethrin (ACYP) on pediculosis due to Haematopinus tuberculatus and to evaluate the influence of the treatment on productive and reproductive performance in buffaloes (Bubalus bubalis) reared in an intensive system. The trial was performed on 56 pluriparous buffaloes at 86.8 ± 8.1 d in milk. The animals underwent individual louse count and were divided into 2 homogenous groups according to louse count, age, number of lactations, days in milk, live BW, BCS, pregnancy status, and milk yield. Group A (n = 28) was treated by a pour-on formulation of ACYP, and Group S (n = 28) was treated by pour-on saline solution. Individual louse counts were performed weekly on 10 buffaloes in each group. Feed intake was recorded daily and the total mixed ration, individual ingredients, and orts were analyzed to calculate DM ingestion. Individual milk yield was recorded daily and milk samples were analyzed at the beginning of the trial, after 4 wk, and at the end of the trial to assess milk composition. Individual BCS was also evaluated simultaneously. Finally, the animals underwent synchronization of ovulation starting 4 wk after treatment and the pregnancy rate and the calving-conception interval were evaluated. Data were analyzed by the Mann-Whitney test and ANOVA for repeated measures. The infestation was constant in Group S, whereas no lice were present in Group A throughout the study. Daily DMI was similar in the 2 groups (16.7 ± 0.4 vs. 16.3 ± 0.3 kg/d in Group A vs. Group S, respectively), although buffaloes in Group A showed higher (P < 0.05) BCS score at the end of the trial (7.39 ± 0.1 vs. 7.14 ± 0.1 in Group A vs. Group S, respectively). The average milk yield/buffalo was higher (P < 0.05) in Group A compared to Group S (10.58 ± 0.1 vs. 10.39 ± 0.1 kg in Group A vs. Group S, respectively) and this was mainly due to the higher milk production recorded in buffaloes at less than 75 d in milk (11.81 ± 0

    This study was designed to compare the quality of liquid-stored buffalo bull spermatozoa in soya lecithin based extender Bioxcell(®) (BIOX), milk (MILK), tris-citric egg yolk (TEY) and egg yolk-citrate (EYC) extender at 5°C. Semen was collected from five Nili-Ravi buffalo (Bubalus bubalis) bulls of 6-7 years of age with artificial vagina over a period of 3 weeks (two consecutive ejaculates once in a week). Semen ejaculates having more than 60% motility were pooled, split into four aliquots, diluted (37°C; 10 × 10(6) motile spermatozoa/ml), cooled from 37 to 5°C in 2 h (0.275°C/min) and stored for 5 days. Sperm motility, viability, plasma membrane integrity (PMI) and normal acrosomal ridge were studied at first, third and fifth day of storage. Higher values of progressive sperm motility (%), sperm viability (%), sperm PMI (%) and normal apical ridge (%) were observed in BIOX, MILK and TEY extenders at first, third and fifth day of storage than EYC extender. Progressive sperm motility, sperm viability and sperm PMI in BIOX(®) extender were not different from MILK and TEY extenders at 1st and third day storage period. However, at fifth day of storage, the values for these parameters remained significantly higher (p<0.05) in BIOX(®) compared with MILK, TEY and EYC extenders. At fifth day of storage, the semen quality parameters for Bioxcell(®) were comparable to those with MILK and TEY extenders at third day of storage. In conclusion, motility, viability and PMI of buffalo bull spermatozoa remained similar in Bioxcell(®) , milk and TEY extender at first and third days of storage at 5°C. Yet, the values for the aforementioned parameters in Bioxcell(®) were higher compared with milk, TEY and EYC extender at fifth day of storage at 5°C. © 2010 Blackwell Verlag GmbH.

    Full Text Available Foram analisados 24 isolados bacterianos oriundos de leite e pele de búfalas (Bubalus bubalis, os quais foram previamente identificados como Rhodococcus equi com o auxílio de fenotipia concisa. Testes fenotípicos complementares e ferramentas moleculares foram utilizados com o objetivo de caracterizar esses isolados, bem como diferenciá-los de outros microrganismos intimamente relacionados. Observaram-se três fenótipos distintos, porém a identificação dos isolados foi inconclusiva. Apenas um dos isolados foi comprovado como sendo R. equi com a realização da PCR espécie-específica, sequenciamento e análise dos fragmentos de DNA. Os demais isolados só foram identificados pelo sequenciamento de fragmento do gene que codifica a região 16S do rRNA universal de bactérias, indicando tratar-se de Dietzia maris. O perfil de susceptibilidade aos antimicrobianos revelou maior resistência dos isolados de D. maris para oxacilina (96% e rifampicina (87%. O isolado de R. equi apresentou resistência à amicacina, oxacilina, penicilina, rifampicina e tetraciclina. Alerta-se para o risco da incorreta identificação dos isolados baseados em testes fenotípicos concisos e para a necessidade de utilização de testes complementares para diferenciação entre R. equi e D. maris.Twenty-four bacterial isolates from milk and skin of buffalo females (Bubalus bubalis, which previously had been identified as Rhodococcus equi by using a restricted number of phenotypical tests for bacterial characterization, were analyzed. The goal of this study was to perform the characterization of these isolates, as well as the differentiation of other microorganisms closely related by using additional phenotypical tests and molecular tools. Based on the phenotypical results, three different biotypes were obtained. However, the identification of the isolates was inconclusive. Only one of the isolates was confirmed as R. equi by the PCR specifically for this species, as

    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 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 mastitis revealed suppression to both CL diameter and function leading to significant reduction in pregnancy outcome of buffalo cows. Copyright © 2016 Elsevier Inc.

    Full Text Available O objetivo do trabalho foi comparar dois diferentes protocolos de extração de DNA de pelos de búfalos (Bubalus bubalis e comparar três regiões de coleta de material (nuca, paleta direita e testa. 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. Also, three sites for the fur source (back of the head, right shoulder and forehead were compared. For the experiments, four animals were used and three replicates for each site on each animal were performed. For protocol 1, the phenol chloroform technique was used, and the CTAB extraction technique was used for protocol 2. Protocol 2 resulted in a higher average of DNA concentration for the fur samples. Considering the body region from where the fur was extracted, there were no significant differences in DNA concentration. However, the forehead showed a higher concentration when extracted with

    Mature spermatozoa have highly condensed DNA that is essentially silent both transcriptionally and translationally. Therefore, post translational modifications are very important for regulating sperm motility, morphology, and for male fertility in general. Protein sumoylation was recently demonstrated in human and rodent spermatozoa, with potential consequences for sperm motility and DNA integrity. We examined the expression and localization of small ubiquitin-related modifier-1 (SUMO-1) in t...

    Tingxian Deng

    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

    Full Text Available Os hematomas placentários executam funções desconhecidas em várias espécies. Na ovelha, estas estruturas ocorrem na zona arcada do placentônio (topos dos septos maternos, região onde ocorre a eritrofagocitose trofoblástica. A função real do hematoma é desconhecida na espécie bufalina, a qual é muito importante no nosso estudo. Há grande possibilidade de transferência de ferro para o feto através destas estruturas, que ocorrem por extravasamento de sangue materno em determinadas regiões dos vilos (junção materno-fetal. Foram usadas placentas de búfalos entre 4-5, 7-8, 9-10 meses de prenhez, imediatamente após sacrifício e fixadas por perfusão de vasos uterinos com paraformaldeído a 4% em 0,1M em tampão fosfato; após a perfusão, os placentônios foram fixados por imersão para microscopia de luz. Depois de 24 horas, as amostras foram cortadas e processadas para inclusão em "paraplast" e "historesina" e coradas pelos métodos de HE, azul de Toluidina, reações de Perls e PAS e tricromos de Gomori e Mallory. Os hematomas estavam presentes em determinadas regiões do placentônio, nos quais havia áreas hemorrágicas entre o epitélio uterino e o trofoblástico, nas placentas de 7-8 e 9-10 meses de prenhez. Células sangüíneas maternas foram encontradas nas células trofoblásticas, elucidando a eritrofagocitose.

    Full Text Available Differently from what one could formerly imagine, that buffalo breeding activity would be solely directed to fill the so called cattle breeding gaps determined by inadequate environmental conditions for ordinary cattle breeding, it has been actually seen that in those areas where breeders could successfully organize industrial-agricultural chains, either on meat or milk and its related products production, there has been an expressive expansion .Buffalo breeding has shown to be an important alternative not only in farms of higher technological level as also , and mainly, on small farms where it has become a key factor for increasing the average income, besides keeping labor force in country areas. This article intends to point out and examine some aspects of buffalo breeding and its potentialities in Brazil.

    Full Text Available Este trabalho objetivou avaliar a elasticidade no queijo mozzarella de leite de búfala para pizza, fabricado com dois diferentes tipos de coagulantes: coalho bovino (80% pepsina e 20% quimosina e o agente coagulante fúngico (mucorpepsina, obtido da fermentação do fungo Mucor miehei, com três temperaturas de filagem (75ºC, 85ºC e 95ºC e quatro períodos de estabilização (7, 17, 27 e 35 dias após o processo de filagem. Os resultados obtidos não apresentaram diferenças significativas entre as temperaturas da água de filagem e os tipos de coagulantes utilizados, somente apresentaram diferenças entre os períodos de estabilização (p<0,01. Os resultados encontrados podem ser explicados pela provável ação da proteólise sobre a matriz proteica dos queijos no decorrer do tempo de estabilização. Portanto, os queijos mozzarella para pizza elaborados com leite de búfala, precisam de um período de estabilização mínimo de vinte e um dias sob refrigeração a 9ºC, para que tenham uma característica funcional de elasticidade aceitável.

    Full Text Available Resumo: Com o objetivo de realizar um estudo dos teores de cobre (Cu, zinco (Zn e ferro (Fe em búfalas com paratuberculose (PTB foram utilizadas 13 búfalas, das raças Murrah, Mediterrâneo e seus mestiços acima de três anos de idade, pertencentes a duas propriedades localizadas nos municípios de São Luiz e São Mateus, no Estado do Maranhão. Os animais foram selecionados de acordo com a presença de sinais clínicos sugestivos de paratuberculose, caracterizados por estado nutricional regular a ruim, diarreia crônica líquida a semi-líquida, desidratação, edema submandibular, anestro prolongado, mastites e verminose gastrintestinal. Foi realizada biópsia retal em todos os animais, para detecção de Mycobacterium avium subsp. paratuberculosis (Map por meio da qPCR, e exames histopatológicos (HE e Ziehl-Neelsen. No Grupo1 sete animais foram positivos para presença de Map, e no Grupo 2 seis foram negativos. Todos os búfalos foram eutanasiados e necropsiados para coleta de diversos tecidos. Parte dos fragmentos foram fixados em formol a 10% para histopatologia e fragmentos de tecido hepático foram congelados para as dosagens dos microminerais (Cu, Zn e Fe. À necropsia todos os animais positivos para PTB apresentavam linfonodos mesentéricos de coloração castanha sugestiva de hemossiderose. Adicionalmente, em um animal foram observados pequenos pontos de cor marrom distribuídos difusamente na mucosa do intestino delgado. Na histopatologia foi observada hemossiderose moderada a acentuada no baço dos animais do Grupo 1. Na dosagem dos microminerais todos os animais com PTB apresentaram níveis abaixo dos valores de referência para Cu e Zn. Observou-se que a média dos teores de Cu dos búfalos com PTB foi 18,0ppm e de Zn 68,6ppm. No Grupo 2 a média dos teores de Cu foi 113,7ppm e de Zn 110,0ppm. Os teores de Fe em ambos os grupos foram elevados (>670ppm. Baseado nos achados clínico-patológicos e nas dosagens de minerais realizadas neste estudo, conclui-se que na região estudada, a PTB agravou o quadro clínico de animais com deficiência de Cu e Zn. Em áreas menos deficientes desses minerais sugere-se que a doença seja capaz de induzir quadros de deficiência mineral secundária.

    Full Text Available This study was carried out to investigate effects of copper sulphate (CuSO4 additive tosemen extenders on sperm parameters:progressive motility, viability, membrane integrityand DNA damage, after semen dilution and cryopreservation. Semen samples of 5 buffalobulls of 3-5 years old were collected at 5 different occasions during the autumn 2011. A totalnumber of 25 samples were used in each examination. Sperm progressive motility andviability were measured at 0 (T0, 60 (T1 and 120 (T2 min after diluting semen in tris-citricacid extender containing 0 (control, 0.004, 0.008, 0.016, 0.032 and 0.064 mg L-1CuSO4. Later,semen was diluted in a tris-citric acid-egg yolk-glycerol extender containing the sameamounts ofCuSO4, cooled to 4̊C and kept refrigerated for 4 hr to equilibrate, spermprogressive motility, viability, membrane integrity and DNA damage were estimated. Then,semen was packed in 0.5 mL French straws and frozen in liquid nitrogen. Later, the frozensemen was thawed in 37 ̊C water bath for 30 sec, and the same parameters as well as totalantioxidant capacity (TAC of the frozen-thawed semen were estimated. The results showedthat copper additive at the rate of 0.032 mg L-1gives a better protection of sperms throughthe process of dilution, equilibration and freeze-thawing than that in control and other Cuconcentrations, while 0.064 mg L-1CuSO4had deleterious effect on the sperm.

    Beyond Ultra-deep Frontier Fields And Legacy Observations (BUFFALO) is an astronomical survey built around the six Hubble Space Telescope (HST) Frontier Fields clusters designed to learn about early galactic assembly and clustering and prepare targets for observations with the James Webb Space Telescope. BUFFALO will place significant new constraints on how and when the most massive and luminous galaxies in the universe formed and how early galaxy formation is linked to dark matter assembly. The same data will also probe the temperature and cross section of dark matter in the massive Frontier Fields galaxy clusters, and tell us how the dark matter, cluster gas, and dynamics of the clusters influence the galaxies in and around them. These studies are possible because the Spitzer Space Telescope, Chandra X-ray Observatory, XMM-Newton, and ground based telescopes have already invested heavily in deep observations around the Frontier Fields, so that the addition of HST observations can yield significant new results.

  18. Tuberculosis diagnostic methods in buffaloes

    Directory of Open Access Journals (Sweden)

    Gabriela Capriogli Oliveira

    2015-07-01

    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.

    2010-02-01

    Full Text Available In buffalo species embryonic mortality is considered one of the major causes of fertility loss, especially in the animals that are not mated during their reproductive period. Embryonic loss in animals mated by artificial insemination (AI is 20-40% during seasons characterized by high number of light hours. Also in buffalo naturally mated the incidence of embryonic mortality is about 20% and a higher incidence is observed between 28- 60 days of gestation in buffaloes that conceive during increasing daylight length. A reduced capacity to secrete progesterone seems to explain in part this embryonic mortality but other as yet unidentified factors contribute between 40-50% to the embryonic losses. Treatments with hCG, GnRH agonist or progesterone on Days 5 after AI not always reduce embryonic mortality in buffalo species. Embryonic mortality in buffaloes appears to occur later (Day 25-40 than in cattle and P4 treatments should perhaps be applied later in buffaloes.

    2010-02-01

    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.

    Full Text Available The objective of this study was to quantify lactoferrin (Lfe in buffalo milk and to examine the factors affecting milk Lfe, such as the lactation stage, daily milk yield, parity, and milk somatic cells count (SCC. Milk Lfe concentration was detected by the SDS-polyacrilamide gel electrophoresis (SDS-PAGE. The overall mean of Lfe concentration was 0.332±0.165 g/L and ranged from 0.030 to 0.813 g/L. Milk Lfe concentrations increased (P<0.01 with the increase of days in milk, but it was not affected by parity. It was estimated an increase of 0.0015 g/L daily of Lfe in milk during lactation. Milk Lfe concentration was significantly affected by SCC. The differences became significant when the levels of SCC increased up to 200.000/mL. This is the first investigation on the levels of Lfe in buffalo milk in reference to daily milk production, lactation stage, parity and SCC. Further studies are needed to clarify the relationship between Lfe and SCC in buffalo milk.

    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.

    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 The number of buffaloes in the American continent is growing at the explosive rate of 12.7 % a year, well above all other continents. Within this context the different situations of the southern part of South America are described, those countries that two hundred years ago were part of the River Plate Viceroyship and the Chile General Command, both of them part of the Spanish empire. The first steps of buffaloes in Paraguay, Bolivia and Uruguay. The expansion of buffaloes in Argentina and their recent start up in Chile. The production systems in the region are described, principally Argentina and Paraguay. The major changes and expansion of agriculture in Argentina are displacing cattle production from the North towards the Tropics, where buffalo has proven to be very superior in productivity compared to cattle production thanks to its very good adaptation to the local conditions. In Paraguay, a totally subtropical country, something very similar is happening. Paraguay has consolidated its sales of buffalo hides and beef. Argentina is well on its way to having a very efficient buffalo beef marketing competing with cattle of the highest quality. Buffalo milk production is still not mature in these countries, although there are several projects underway in Uruguay, Bolivia and Argentina.

    Full Text Available The milk is an important food because it contents Conjugated Linoleic Acids (CLA. These fatty acids are synthesized in mammary gland under action of the enzyme Stearoyl CoA-Desaturase (SCD and have showed some positive effects in human disease prevention and treatments. A variation of CLA in milk fat exists and can be partially explained by the different levels of expression of SCD. The aim was to study part of the encoding regions of SCD´s gene using PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism. Genomic DNA was extracted from lactating Murrah females. After this, PCR reactions were made by using primers Z43D1 that encloses exon I, II and intron I. The fragments amplified are composed by 938 pb. Then, RFLP techniques were applied in the fragments using the restriction enzymes Pst I and Sma I. The enzyme Pst I has generated fragments of 788pb and 150bp and the Sma I has generated fragments of 693pb and 245pb. All the animals showed the same migration standard for both enzymes, characterizing a genetic monomorphism for this region of SCD gene. The analysis determined that there aren’t genetic differences between these animals in the studied regions by using Pst I and Sma I enzymes.

Fueron analizadas informaciones de 23.534 muestras de controles de leche (RCS, referentes a 2.198 lactancias de animales de la raza murrah con edades entre los dos y quince años, hijas de 187 reproductores; estos muestreos fueron realizados durante siete años. Los resultados indicaron que de manera general, ocurrieron bajos, medios, altos y muy altos RCS para, 96,34%, 2,3%, 0,96% y 0,4% de las muestras, respectivamente. Las clases de bajos y medios RCS, fueron las que presentaron las mayores frecuencias, confirmando que en búfalos, hay una tendencia a menores recuentos que en los bovinos. Se presentaron diferencias entre las medias del RCS por orden de parto y por estación de parto, y hubo diferencias estadísticamente significativas (P < 0,05 para las medias del RCS en algunos controles. En relación con el orden de parto fueron observadas diferencias entre las frecuencias de los RCS, siendo que, de modo general, a medida que aumentó el orden del parto, disminuyó el porcentaje de bajos recuentos y aumentaron las frecuencias de recuentos medios, altos y muy altos. Los resultados indicaron que los efectos de hacienda, año y orden de parto deben ser considerados en la comparación entre animales.

    Polyacrylamide gel electrophoresis of the two digenetic trematodes, Gigantocotyle explanatum from the liver and Gastrothylax crumenifer from the rumen of the water buffalo, Bubalus bubalis revealed the presence of at least six and seven isoenzymes of lactate dehydrogenase (LDH), respectively in a partially purified enzyme preparation. The respective host tissues showed five isoenzymes of LDH, which are characteristic to the vertebrates. Both parachloromercuribenzoate and iodoacetate affected the LDH activity of the parasites and host tissues differently. Spectrophotometric analysis also showed different specific activity and susceptibility to the action of thiol inhibitors. The host LDH was quite stable at 57 degrees C for 30 min, but that of the parasites was less stable.

    2016-02-01

    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.

    Water buffalo are an ancient component of Turkey's domestic livestock resources. Commonly referred to as the Anatolian buffalo the animal is part of the Mediterranean group which includes Syrian, Egyptian and Southeast European animals. Once quite numerous, there have been drastic reductions in their numbers since the 1970s due to intensification of dairy activities, agricultural mechanization and changing consumer preferences. The main areas of distribution are in northwest Turkey in the Marmara and Black Sea Regions. Buffalo are kept in small herds by livestock and mixed crop-livestock farmers. Milk is the main product, meat is largely a by-product of the dairy function and provision of the once-important draught power is now a minor output. Buffalo milk is used to prepare a variety of speciality products but output of both milk and meat is very low in comparison to cattle. Conditions of welfare and health status are not optimal. Internal parasites are a constraint on productivity. Some buffalo are being used for conservation grazing in the Black Sea area to maintain optimal conditions for bird life in a nature reserve. Long neglected by government there are recent activities to establish conservation herds, set up in vitro banks and undertake molecular characterization. More effort is needed by government to promote buffalo production and to engage the general public in conservation of their national heritage.

    1. Gastrothylax crumenifer and Paramphistomum epiclitum parasitize the water buffalo Bubalus bubalis. 2. Gastrothylas hemoglobin consisted of two fractions of ca 30,000 and ca 18,000 by gel filtration. SDS-electrophoresis showed both to be single, ca 15,000 chains. 3. Paramphistomum hemoglobin was ca 16,000 by both gel filtration and SDS-electrophoresis. 4. Reversed-phase chromatography of carboxymethylated trematode and buffalo globins gave single peaks and two peaks, respectively. Although Paramphistomum hemoglobin provided and N-terminal sequence, Gastrothylax hemoglobin did not, suggesting blocked N-terminals. The buffalo sequences were found to be identical to the sequences of the alpha and beta chains of bovine hemoglobin. 5. Although Paramphistomum hemoglobin consists of only one chain, Gastrothylax hemoglobin consists either of one chain which aggregates to a dimer or of two different chains, only one of which aggregates to a dimer.

    Full Text Available Water buffaloes in Turkey originate from Mediterranean Water Buffaloes, a subgroup of river water buffaloes and are known as Anatolian Water Buffalo. During the 1970’s the number of water buffaloes in Turkey was one million, but in 2010 this figure dropped to about 85.000. Thanks to the incentives introduced for water buffalo husbandry in recent years, the water buffalo population has risen to 143.073 heads. Water buffalo husbandry in Turkey is performed in some provinces of the Black Sea, Marmara and Central Anatolian Regions. The provinces with the highest amount of water buffalo existence are listed as Samsun, Diyarbakır, Istanbul, Tokat, Bitlis, Muş, Afyon, Kayseri, Sivas and Amasya. Breeding style in Turkey is in the form small family business, with an average of 1-5 animals per enterprise. Family enterprises are keeping water buffaloes for their own consumption. Mostly breeding in modern enterprises formed for indoor barn breeding, the size of the herds is around 50 to 100 heads. Being done only at swamps or waterfronts in the past, water buffalo husbandry increasingly takes place in modern facilities nowadays. The colour of Anatolian Water Buffaloes is generally black and their horns curved backwards, are called arch horns in Turkey. The lactation milk yield and lactation length in Anatolian Water Buffaloes are between 800 and 1100 kg and about 180-280 days respectively. It is demonstrated that they varied according to effects of environmental factors, care and feeding. Adult water buffalo’s live weight is about 411-518 kg. The first insemination age of water buffalo is 32 to 43 months and during a lifespan the number of lactation periods is 5 to 10. For adult water buffalo at withers the height of females is being expressed as around 135 cm. Calves are generally breastfed for 3-4 months. Generally, water buffaloes are milked twice a day in the village farms by hand.

    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.

    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.

    2014-08-01

    Full Text Available Mastitis is an important disease which causes economic losses in the water buffalo breeding. According to severity, duration and primary, mastitis is generally classified as clinical and subclinical. Because of contamination from other animals in the herd, subclinical mastitis is a important dairy herd problem. However, clinical mastitis is a clinical case created by deformation of udder gland and decreasing milk yield. Staphylococcus aureus, Escherichia coli, Streptococcus agalactia and Streptococcus dysgalactia are in clinical mastitis, but Escherichia coli, Staphylococcus aureus, Pseudomonas, Streptococcus agalactia and Streptococcus dysgalactia are the most common isolated microorganisms in subclinical mastitis. Due to mastitis caused by these microorganisms in Water Buffalo, abnormality in the structure of milk are observed, and it causes economic losses to farmers from reduced production. Therefore, the detection of effective factors on mastitis and taking of the necessary precautions are very important. In this review, mastitis case in water Buffalo and its effects were discussed.

    2014-06-01

    Full Text Available The aim of the present study was to determine different affections of the salivary ducts in buffaloes with special reference to diagnosis and treatment. The study was carried out on 39 buffaloes suffering from different affections of the salivary ducts. The recorded affections of the salivary ducts in buffaloes include; ectasia of the parotid duct (21 cases, parotid duct fistula (15 cases and sialocele (3 cases. Each case was subjected to full study including case history, clinical examination, diagnosis, and treatment whenever possible. Exploratory puncture and radiography were used for confirmation of diagnosis. Intraoral marsupialization was performed for treatment of parotid duct ectasia. Salivary fistula was corrected by one of two successful techniques; the first by reconstruction of the parotid duct and the second by ligation of the parotid duct just caudal to the fistula opening. Sialoceles were corrected by removal of the mandibular salivary gland of the affected side.

    The present short communication puts on record a case of bilateral, multiple follicular cysts in a water buffalo along with a detailed description of its ovarian biometry and follicular fluid composition. The ovarian weight and biometrical parameters were much higher than in normal cycling buffaloes. A total of three follicular cysts were observed, two on the right ovary and one on the left ovary, measuring 4.9, 3.0 and 2.6 cm yielding 21, 9 and 5 ml of follicular fluid, respectively. The cystic fluid was deep yellow in colour with a viscous consistency. The follicular fluid concentrations of glucose, total protein, cholesterol, acid phosphatase, calcium, phosphorus and progesterone in all the cysts were within the range reported previously in normal buffalo follicular fluid; however, the alkaline phosphatase concentration in cyst 1 and total bilirubin concentration in cysts 1 and 2 were higher than the values in normal follicular fluid. In contrast, the levels of urea nitrogen in cysts 1 and 3, and oestradiol in cyst 3 were lower than the normal values. All the three follicles had an oestradiol to progesterone ratio less than 1. The results of our study suggest that follicular cysts in buffalo are oestrogenically inactive and have an altered concentration of certain biochemical and hormonal constituents.

    Somvanshi, R

    2011-08-01

    Scant information is available on papillomatosis in buffaloes, and it is an almost unknown disease. It has been described from India, Italy and Turkey. Buffalo papillomatosis occurs in cutaneous and mucosal forms. Cutaneous papillomatosis is manifested as cutaneous wart (CW) and teat papilloma types. The condition is known to be caused by bovine papillomaviruses (BPV)-1 and 2 and their mixed infections. Buffalo CWs are experimentally transmissible to hamsters, cattle as well as buffaloes. Once BPV establishes infection in buffaloes, infection spreads from buffalo to buffalo, without cattle intermediary. Histologically, CWs are mostly diagnosed as fibropapillomas. The mucosal form occurs as urinary bladder tumours similar to enzootic bovine haematuria which is also associated with bracken fern infested areas. BPVs are yet to be demonstrated in teat papillomas and urinary bladder tumours of buffalo cases. Papillomatosis in buffaloes is a little-known disease, but it is a separate infectious ailment of buffaloes and deserves more attention by researchers. © 2011 Blackwell Verlag GmbH.

  13. Genetic analysis of congenital hemimelia in buffaloes from Southern Italy

    Full Text Available Hemimelia is a common congenital limb abnormality found in water buffaloes from Southern Italy. In humans, such defect has been associated with mutations in WNT7A and ESCO2 genes. These two candidate genes were analyzed by polymerase chain reaction in the genomic DNA extracted from the blood of buffaloes, and cows for control. No differences in WNT7A and ESCO2 sequences between affected and healthy buffaloes were identified. However, comparing sequences of control cows and buffaloes, WNT7A showed simple species polymorphisms, and ESCO2 showed seven base-pair substitutions. These results demonstrate that limb malformations in buffaloes are not related to congenital defects in WNT7A gene. Interestingly, our findings highlight for the first time differences in the sequences of WNT7A and ESCO2 genes between buffaloes and cows.

    2012-05-01

    Full Text Available Fertility in buffalo is low. That could be a question of species adaptation in new climate or a genetic trait. Scientists think buffaloes entered the South-est of Europe on two ways one with the Hune and Avar people coming trough the North of Black Sea up to the intra Charpathian Hils and a later one more prolonged with penetratio trough Egypt, Small Asia and Greece at the time when some people migrated up to the Danube River. Buffaloes which originated from Egypt were domesticated before the ones that came through the North of Black Sea. That means in Romania there are two different buffalo populations: the Carpathian Buffalo adapted to reproduce in a cold and wet climate, outside the area of its wild ancestors and a Danube Buffalo that underwent more influence domestication apart. These two populations reproduced separately by territorial state insulation. All buffalo breeds including the ones in the native domestication area show grouped calving. The present paper has to answer if grouped calving in buffalo is due to photoperiodic exchange along the year or to the poor feeding in some seasons. The answer to this question will decide the actions needed to improve buffalo cows’ fertility.

    Full Text Available Buffalo’s production represents an important option as input source in livestock systems located in areas with little profitability by cattle. In mostly farms, cattle and buffalos are breeding together, due that in Argentina, to carry out buffalo’s production is in an extensive way, with the aim to produce meat – mostly- milk – for this production nutritional supplements are used- and leathers. Brucellosis is zoonic illnesses from bacteria belong to Brucella which caused human human health problems by contaminated food ingestion or to those who are in touch with cattle. In Argentina, exist the National Control an Elimination Program for cattle Brucellosis, which include buffalos also, there is inclosed female vaccination and serologic segregation of positive reactants. Diagnosis techniques ruled for cattle brucellosis are BPA (Buffered Plate Agglutination, Tube seroaglutination and 2MercaptoEthanol. International reference test is Complement Fixation. By means of this present work, we pretend to evaluate the serologic diagnosis utility, ruled to the buffalos and compare obtained results by BPA, SAT and 2ME with Complement Fixation Test. In the present communication are presented results from the use of diagnosis techniques recommended by SENASA (National Service of Sanity and Quality Agro-Food to buffalo’s serums which belong to nine farms from NE Corrientes State. Obtained results show that association o BPA as Screening Test and SAT and 2ME as Confirmated Test has a valid correlation for the detection of positive animals with the reference technique Complement Fixation.

    Govind Narayan Purohit

    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.

    Cryopreservation of immature testis is a feasible approach for germplasm preservation of male animals. Combinations of dimethyl sulfoxide (DMSO) and foetal bovine serum (FBS) are used for testis cryopreservation. However, an alternative to FBS is needed, because FBS is expensive. Buffalo ocular fluid (BuOF), a slaughter house by-product, could be an economical option. The objective of the present study was to assess whether BuOF can replace FBS for cryopreservation of immature mouse (Mus musculus), rat (Rattus norvegicus), and buffalo (Bubalus bubalis) testes. Results showed that rodent and buffalo testes frozen in DMSO (10% for rodents and 20% for buffalo) with 20% FBS or BuOF had similar numbers of viable and DNA-damaged cells (P > 0.05). The expression of cell proliferation- (PCNA) and apoptosis-specific proteins (Annexin V and BAX/BCL2 ratio) were also comparable in mouse and buffalo testes frozen in DMSO with FBS or BuOF (P > 0.05). Interestingly, rat testis frozen in DMSO with BuOF had lower expression of Annexin V protein than testis frozen in DMSO with FBS (P  0.05). These findings provide evidence that BuOF has potential to replace FBS for cryopreservation of immature rodent and buffalo testis. Further investigation is needed to explore whether BuOF can replace FBS for testis cryopreservation of other species. Copyright © 2016 Elsevier Inc. All rights reserved.

    Several farms in the Northeast of Brazil were investigated for Mycobacterium avium subsp. paratuberculosis infection in order to identify the occurrence of paratuberculosis in buffaloes. Samples were obtained from 17 farms, two slaughter houses, and a quarantine area in the Northeast. About 15,000 buffaloes of the Murrah, Mediterranean, and Jafarabadi breed as well as their crossbreeds were evaluated for meat, dairy, and mixed farms with semi-intensive or extensive breeding practices. For diagnostic purposes, postmortem and histopathological examination, including Ziehl-Neelsen test of fecal smears and scraped intestinal mucosa were performed. PCR was applied for fecal samples, mesenteric lymph nodes, and intestines. Six Johne's disease-positive farms, which together with those previously identified, indicate that the disease is spread through the Brazilian Northeast, similar to what occurs in cattle herds in other regions of the country. The increase in prevalence of paratuberculosis is a consequence of introduction of animals from other regions without adequate veterinary assistance and due to the little official attention paid to this initially silent and chronic disease.

    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...

    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 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

    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.

    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.

    Odili, Julius Beneoluchi; Mohmad Kahar, Mohd Nizam

    2016-01-01

    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 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.

    Full Text Available ABSTRACTThe objective of this study was to evaluate the performance of 17 buffaloes (Mediterranean, from birth to slaughter age (720 days with monthly measures of weight, thoracic perimeter, body length, and height at withers. At the end of experimental period, the animals were separated into two different groups for statistical analysis according to slaughter weight: light body weight (LBW, mean 517 kg and heavy body weight (HBW, mean 568 kg. Buffalo growth occurs in the same way up to weaning age, and after that, two distinct groups grow in different forms in the same conditions of management and feeding. Body weight can be estimated according to age, thoracic perimeter, height, and length, showing high correlations. Buffaloes show growth in a sigmoid-curve model.

  17. Effects of some sugars, amino acids, glycerol and alpha-glycerophosphate on oxygen uptake of some digenetic trematodes.

    Effect of various substrates on the oxygen uptake of some digenetic trematodes -- Srivastavaia indica, Gastrothylax crumenifer, Gigantocotyle explanatum from the buffalo, Bubalus bubalis and Isoparorchis hypselobagri from the fish Wallago attu was studied. In all the four species, the effect of various substrates except maltose was found to be stimulatory. The inhibitory or stimulatory effect of these substrates on oxygen uptake reflects the importance of these compounds in the energy metabolism. In spite of the fact that these trematodes were subjected to similar concentration of substrates, the percentage change in oxygen uptake is different in each of the trematodes, the differential utilization is probably related to the different ecophysiological conditions of the habitat of these trematodes. Such studies can be useful in devising better in vitro culture media for these trematodes.

    Quantitative estimation of absolute levels and in vitro release of acetylcholinesterase (AChE) in seven species of digenetic trematodes: Isoparorchis hypselobagri from the swim bladder of catfish, Wallago attu; Srivastavaia indica and Gastrothylax crumenifer from the rumen, and Gigantocotyle explanatum from the liver of the water buffalo, Bubalus bubalis; Fasciolopsis buski, Echinostoma malayanum from the small intestine and Gastrodiscoides hominis from the caecum of the pig, Sus scrofa revealed that the enzyme is present in remarkably high quantities in species which inhibit gastrointestinal tract compared with those that parasitize liver and swim bladder. The rate of in vitro release of AChE also varies with the species which supports the view that such differential secretion probably takes place in situ as well to counteract peristalsis and it is a biochemical adaptation on the part of these trematodes.

    Following the recent invasion of bovine tuberculosis (BTB) into the Kruger National Park, South Africa, we conducted a study on the maintenance host, African buffalo, to investigate associations between BTB prevalence and calf:cow ratio, age structure, body condition, and endoparasite load. Statistical analyses compared herds of zero, medium (1–40%), and high (>40%) BTB prevalence. To control for ecological variation across the park we collected data in northern, central, and southern regions and restricted some analyses to particular regions of the park. Body condition declined over the course of the 2001 dry season, and buffaloes in the southern region of the park, with the highest BTB prevalence, were in worse condition than buffaloes in the northern region (which receives less annual rainfall but is still virtually BTB-free). Herd-level analyses of the entire park, the south and central regions, and just the southern region all indicated that herds of higher BTB prevalence were in worse condition and lost condition faster through the dry season than herds of lower BTB prevalence. Fecal endoparasite egg counts increased during the dry season and were associated with both decreased body condition and increased BTB prevalence. Although we did not detect any obvious effect of BTB on the age structure of the buffalo population, our findings indicate early symptoms of wider scale BTB-related ecological disturbances: buffalo herds with high BTB prevalence appear more vulnerable to drought (because of a decrease in body condition and an increase in endoparasite load), and because lions selectively kill weak buffaloes their prey base is accumulating a disproportionately high prevalence of BTB, to which lions are susceptible.Rea10.1890/02-5266d More: http://www.esajournals.org/doi/abs

    Full Text Available Leptin is a 16-kDa protein secreted predominantly from white adipose tissue and performs important roles in controlling the body weight, feed intake, immune function, production and reproduction. In present study, buffalo leptin gene was analyzed using DNA markers for polymorphism and its association with production traits. The PCR-RFLP analysis of leptin gene using BsaAI, Sau3AI and Kpn2I restriction enzymes revealed monomorphism. The PCR-SSCP followed by DNA sequencing of Murrah buffalo leptin gene spanning exon III revealed two SNPs viz., c.25 T>C and c.316A>G, which were used to genotype the Murrah, Surti and Bhadawari populations. The c.25 T>C allele frequencies was found 0.81 and 0.19 for C and T in Murrah; 0.65 and 0.35 for C and T in Surti and 0.65 and 0.35 for C and T in Bhadawari buffaloes respectively. The c.25T>C genotypes were not in Hardy-Weinberg proportions, however c.316A>G genotypes maintained equilibrium at this locus in the populations studied. The c.316A>G SNP allele frequencies were observed in Murrah 0.31 and 0.69 for A and G; Surti 0.3 and 0.7 for A and G and Bhadawari 0.3 and 0.7 for A and G respectively. The Murrah buffalo leptin allelic variant sequences revealed 99 % similarity with cattle sequence. The statistical analysis using general linear model procedure indicated that Murrah buffalo leptin c.25 T>C and c.316A>G SNP genotypes were not related significantly (P>0.01 with Murrah buffalo milk production traits viz; milk yield, fat percentage and SNF percentage.

  1. Economic Feed Utilization for Dairy Buffalo Under Intensive Agricultural System

    2010-02-01

    Full Text Available The national strategies for the irrigated intensive agricultural system in developing countries should focus upon Producing less expensive milk from dairy buffaloes that, efficiently, utilize the limited expensive produced feed resources. Therefore, planning for the least cost feeds combination is the most recommended approach to keep buffalo milk price at a competitive level and being low enough to make milk available for the major proportion of the low-income households, particularly “Vulnerable Groups”. Estimation of the least cost feed ration combination of the limited expensive feed resources were conducted from a recent farm survey of the dairy buffalo performances and the feed use pattern in Egypt. The estimated average production elasticity of fodder, concentrate feeds mix and straw, implies that their shares in generated buffalo milk income are 41.7%, 35%, and 23.3%, respectively.. The response of the human labor was of negative direction and statistically insignificant. This means that the labor used per dairy buffalo was beyond the economic level, that reflects the excess farm-family labor involved in such activity, because they have almost nil opportunity income of off farm work. The other capital inputs have small positive effect on milk production, The average marginal return from milk per onedollar expenditure reached $.1.08 for fodder, and $ 1.04 for concentrated feed mix, i.e. it is feasible to expand the usage of fodder more than concentrates. The wheat straw has shown uneconomic efficiency. Therefore, it is recommended to limit its level in the ration. The least cost ration reduces feed cost of one ton of buffalo milk equivalent (4% fat by 22%. The less costs of production will strength the competition of domestic supply either against in the international export market or against the dumping policies followed by exporters to the domestic market.

    Full Text Available Escherichia coli O26 is considered to be one of the most important food-borne pathogen. In this study, 120 buffalo milk samples collected in Lazio and in Apulia regions were tested for the presence of E. coli O26. One buffalo milk sample (0,8% tested positive for E. coli O26; the isolate was positive at the verocytotoxicity test and it showed resistance properties to different antimicrobial classes. These preliminary results highlight the need to monitor the foods of animal origin used for production and eaten by a wide range of persons, respect VTEC organism.

    2010-02-01

    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 Objective. Characterize the follicular dynamics and luteal growth and regression pattern of multiparous (MB and heifer (BH Murrah buffaloes in Colombian tropical conditions. Material and methods. Ten MB and ten BH were synchronized with a progesterone-releasing intravaginal device. No artificial insemination was performed during the estrous and daily ultrasound examinations were performed 15 days later to determine the number and diameter of the structures present in both ovaries in the subsequent natural estrous cycle. The Student’s T test was used to evaluate differences between MB and BH. All data are presented as mean ± standard deviation. Results. The length of the estrous cycle was 22.00±4.50 days for MB and 22.00±2.70 days for BH. Follicular growth occurs in one (n=1; 5.89%, two (n=14; 82.35% or three waves (n=2; 11.76%. The first wave initiated the day after ovulation with the recruitment of 8.33±2.06 and 10.00±2.72 follicles in MB and BH, while the second wave started on day 11.00±2.00 and 10.50±2.82, presenting 8.37±2.26 and 8.00±1.51 follicles. The third wave began on day 16.21±3.10 showing 6.50±1.70 follicles, only BM had three waves. The maximum luteal diameter was 19.58±4.16 mm and 17.74±3.32 mm respectively. There were no significant differences between the groups for these variables. Conclusions. These results show that the follicular development in buffaloes occurs in waves, where two waves is the most common pattern, as previously reported by other authors.

    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.

    Full Text Available The present study comprised of 602 disposal records of adult Murrah buffaloes , spread over a period of 16 years from 1985 to 2000 at NDRI, Karnal, Haryana. Analysed data showed that the reproductive problems (38.62, low milk production (24.01 and udder problems (22.76 were the three major reasons of culling in adult Murrah buffaloes . The culling of cows due to involuntary reason (reproductive problems, udder problems and locomotive disorders accounted for nearly 63.68 percent of total culling in Murrah buffaloes in the NDRI herd. The data revealed that maximum mortality occurred due to digestive problems accounting for 30.89 percent followed by cardio-vascular problems (26.02 percent, respiratory problems (21.14 percent, parasitic problems (8.13 percent and uro-genital problems (5.69 percent. The results showed that there is a scope for further improvement in production and reproductive efficiency through better monitoring of reproduction and udder health status of the buffaloes. The high involuntary culling rate not only makes the dairy enterprises economically less profitable but also reduces the genetic improvement by lowering the selection differential for milk production.

    The presence of lymphoma in buffaloes was first reported in India in the 1960s. The disease is similar to Enzootic Bovine Leucosis (EBL) caused by Bovine leukemia virus (BLV) in cattle; however, according to our results and those of other studies, the etiology of these lymphomas in buffalo do not appear to be associated with BLV. The objectives of this study are to describe four cases of the disease in buffaloes belonging to the same herd in the Amazon region of Brazil and to perform a clinical-anatomopathological, immunohistochemical, and etiological study of the lymphomas. Over a period of ten years, four buffaloes were observed presenting progressive weight loss, swelling of peripheral lymph nodes, and nodules in the subcutaneous tissue. Upon necropsy, whitish-colored tumor masses were observed in the form of nodules in the subcutaneous tissue, along with miliary nodules on the serosal surfaces of abdominal and thoracic organs and tumors in lymph nodes and other organs. Neoplastic lymphocyte proliferation was observed through histopathology. An immunohistochemical study revealed that the neoplasias were formed by proliferation of predominantly B lymphocytes. The presence of BLV genome was not detected in the lymphomas when using the real-time PCR technique, nor was it detected through immunohistochemical staining using monoclonal antibodies against two viral proteins. Bovine herpesvirus 6 was not detected in the tumors. However, Bovine immunodeficiency virus (BIV) was detected in samples of lymphoma and in the lymph nodes and kidneys of one of the animals. The occurrence of lymphoma in buffaloes is reported for the first time in Brazil and is characterized by B-cell multicentric lymphoma. The etiology of the disease does not appear to be associated with BLV; however, the detection of BIV in samples of lymphoma from one sick animal deserves further study, considering the oncogenic potential of this virus.

  20. Rotavirus diarrhoea in Buffaloes: epidemiology, pathogenesys and prophilaxis

    Directory of Open Access Journals (Sweden)

    U. Pagnini

    2010-02-01

    Full Text Available Globally, rotavirus infection is the most important cause of severe diarrhea in infants and animals. In this report, we review the results of pathogenesys studies, strain surveillance and characterization studies published and discuss new insights gained from these studies on the potential mechanisms of the evolution and spread of new rotavirus strains. Early epidemiological studies in Italian buffalo herds revealed the predominance of strains with G8 specificity and detected strains with the rare, RRV-like, VP4 P[3] genotype. In an our previous study 125 fecal samples were collected from buffalo calves affected with diarrhoea, in seven dairy farms in Southern Italy. Rotaviruses were detected in 21 samples (16.8% by an immunochromatographic assay and by reverse transcription-PCR (RT-PCR. Analysis of the VP7 gene revealed that 57% (12 of 21 of the isolates were G6, 23.8% were G8 (5 of 21 and 19% (4 of 21 were G10. Analysis of the VP4 revealed that 71.4% (15 of 21 of the isolates were P[5] and that 28.6% (6 of 21 were P[1]. The most common combination of G and P types was P[5],G6 (57%, followed by P[1],G10 (19%, P[5],G8 (14% and P[1],G8 (9.5%. While P[5],G6 rotaviruses are very common in Italian bovine herds, the antigenic combination P[1],G10 is unusual and presumably derives from reassortment between P[1] and G10 strains, that appear to be more frequent in buffaloes and bovines, respectively. The presence of bovine-like G and P serotypes suggests that in Italy the epidemiology of buffalo rotaviruses overlaps the epidemiology of bovine rotaviruses, presumably because of the strict species affinity and/or of the intermingled distribution over the same geographical areas of the buffalo and bovine herds.

    Full Text Available Cow and buffalo milk and camel milk were analyzed and compared for processing related parameters. The average heat stability of cow, buffalo and camel milk samples analyzed was 1807.4 seconds, 1574.6 seconds and 133.6 seconds respectively at 140 °C. Thus, the heat stability of camel milk was significantly lower than the cow milk and buffalo milk. The average rennet coagulation time (RCT of cow, buffalo and camel milk was 310.6 seconds, 257.4 seconds and 604.2 seconds respectively. Thus, RCT of camel milk was significantly higher than the cow milk and buffalo milk. The camel, cow and buffalo milk samples showed negative alcohol stability. The rate of acidity was increased propositionally with time in camel milk with no curd formation and weaker body.

    2016-08-01

    Intense selection of buffaloes for milk production at organized herds of the country without giving due attention to fertility traits has lead to deterioration in their performances. The study was initiated to assess the relationship between milk production and productivity with fertility in Murrah buffaloes. In the present study, fertility was defined in terms of pregnancy rate of Murrah buffaloes. Pregnancy rate measures the percentage of non-pregnant animals that become pregnant during each oestrous cycle. Data pertaining to 1224 lactation records of Murrah buffaloes spread over a period 22 years from 1993 to 2014 were analyzed in the study. It was observed that pregnancy rate is negatively associated with 305days or less milk yield (-0.08±0.04) and wet average (-0.12±0.02) and positively associated with life time (0.15±0.03) in Murrah buffaloes. Wet average is defined as average daily milk yield per lactation of Murrah buffaloes. To achieve around 2000kg 305days or less milk yield and 7.5kg wet average, the level of pregnancy rate in Murrah buffaloes should vary between 30 and 50%. The per unit change in pregnancy rate with respect to milk yield in Murrah buffaloes, were studied using regression analysis. The results suggest that increasing hundred kilogram in 305days or one kilogram milk yield per day in 305days, pregnancy rate reduced by 0.9% in overall lactations of Murrah buffaloes. By increasing hundred kilogram life time 305days or less milk yield and one kilogram life time wet average, pregnancy rate of Murrah buffaloes reduced by about 0.2% and 0.34%, respectively. The study quantifies the decline of pregnancy rate with increase of lactation milk yield and wet average in Murrah buffaloes and emphasis the importance of fertility i.e. pregnancy rate in the evaluation and breeding programmes of Murrah buffaloes.

    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.

    Brebes District is one of the centre of grazing buffalo in Indonesia that involve thousands of rearers usually kept as a family savings. This paper highlighted the availability of land and the role of the grazing land for the durability of the maintenance of buffalo in Brebes Regency. The information obtained is from interviewed the livestock facilitators in the sub-district (primary data) and from statistic of agriculture in Brebes Regency 2014 (secondary data). Generally the buffalo kept semi-intensively and commonly the buffaloes graze in the fields that are not used from morning until evening and during nights buffaloes are placed in the stalls. Rearers chose the semi-intensive system in rearing the buffalo because it is considered easy to manage and they do not need to provide fresh money to prepare the roughage for feed, because commonly the grazing buffalo are shepherd by herdman that will receive buffalo as their payment. The population density is very high (1.056 heads/km2), the buffalo ownership is between 2-4 head/households; generally the location of the grazing land is in the forest, rice fields fallow, and sleeping land, and estimated that greenfeed stock is still available abunandtly, on the other hand the urban land is less capacity of feed. The spread of buffalo is only in 125 villages from 297 villages in Brebes. The acceptance of buffalo business is around IDR 3.5 million to IDR 7.5 million/family/year. The availability of grazing land strongly influence the maintaining of buffalo farming by rearers.

    A proposed formula for modifying buffalo milk for infant feeding was described. Buffalo milk was diluted with four parts of whey that was produced by addition of citric acid or lemon juice to milk and neutralization with sodium bicarbonate. The chemical composition and the properties of the proposed formula were compared with raw buffalo milk, human milk and buffalo milk modified by the ordinary method. The proposed formula was characterised by low casein/whey protein N comparable to human milk and by curd tension.

  11. A Review of Recent Developments in Buffalo Reproduction — A Review

    2015-03-01

    Full Text Available The buffalo is an important livestock resource in several countries of South Asia and the Mediterranean regions. However, reproductive efficiency is compromised due to known problems of biological and management origins, such as lack of animal selection and poor nutrition. Under optimal conditions puberty is attained at 15 to 18 months in river buffalo, 21 to 24 months in swamp buffalo and is influenced by genotype, nutrition, management and climate. However, under field conditions these values deteriorate up to a significant extant. To improve reproductive efficiency, several protocols of oestrus and ovulation synchronization have been adopted from their use in commercial cattle production. These protocols yield encouraging pregnancy rates of (30% to 50%, which are comparable to those achieved in buffaloes bred at natural oestrus. The use of sexed semen in buffalo heifers also showed promising pregnancy rates (50% when compared with conventional non-sexed semen. Assisted reproductive technologies have been transferred and adapted to buffalo but the efficiency of these technologies are low. However, these latest technologies offer the opportunity to accelerate the genetic gain in the buffalo industry after improving the technology and reducing its cost. Most buffaloes are kept under the small holder farming system in developing countries. Hence, future research should focus on simple, adoptable and impact- oriented approaches which identify the factors determining low fertility and oestrus behaviour in this species. Furthermore, role of kisspeptin needs to be explored in buffalo.

    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. 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. 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. 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.

    Full Text Available Aim: The present study was performed to investigate the effect of genetic and non-genetic factors affecting milk fat yield and to estimate genetic parameters of monthly test day fat yields (MTDFY and lactation 305-day fat yield (L305FY in Murrah buffaloes. Materials and Methods: The data on total of 10381 MTDFY records comprising the first four lactations of 470 Murrah buffaloes calved from 1993 to 2014 were assessed. These buffaloes were sired by 75 bulls maintained in an organized farm at ICAR-National Dairy Research Institute, Karnal. Least squares maximum likelihood program was used to estimate genetic and non-genetic parameters. Heritability estimates were obtained using paternal half-sib correlation method. Genetic and phenotypic correlations among MTDFY, and 305-day fat yield were calculated from the analysis of variance and covariance matrix among sire groups. Results: The overall least squares mean of L305FY was found to be 175.74±4.12 kg. The least squares mean of overall MTDFY ranged from 3.33±0.14 kg (TD-11 to 7.06±0.17 kg (TD-3. The h2 estimate of L305FY was found to be 0.33±0.16 in this study. The estimates of phenotypic and genetic correlations between 305-day fat yield and different MTDFY ranged from 0.32 to 0.48 and 0.51 to 0.99, respectively. Conclusions: In this study, all the genetic and non-genetic factors except age at the first calving group, significantly affected the traits under study. The estimates of phenotypic and genetic correlations of MTDFY with 305-day fat yield was generally higher in the MTDFY-5 of lactation suggesting that this TD yields could be used as the selection criteria for early evaluation and selection of Murrah buffaloes.

    Full Text Available On the basis of individual indices, the productive characters of buffaloes was formulated and it was noticed that the dairy farmers had fair management index (between 71 to 80 %. As regards quantity and quality of milk it was noticed that the milk yield was 5.27, 6.21 and 7.2 kg in group I, II and III respectively. The corresponding fat and SNF contents of milk were 6.17 and 8.75, 6.8 and 8.8 and 7.2 and 9.0 % respectively. It was also noticed that the level of management influenced the production in buffaloes. The production under satisfactory management status was 3 to 4, 4 to 5 and 5 to 7 kg under satisfactory, fair and good management index while it was 10 to 14 kg under very good management index. The milk produced by the buffaloes under all the three herd size groups was meeting out the fat content standard according to PFA rules prescribed for Maharashtra but the milk produced under herd size group I and II did not meet out the standards prescribed for SNF content.

    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 multocida B:2 than buffaloes. Copyright © 2015 Elsevier Ltd. All rights reserved.

    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.

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

    Directory of Open Access Journals (Sweden)

    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

The average length of the estrous cycle was 21.75±0.53 and 27.0±0.58 days in 2- and 3- wave cycle respectively. The duration of the CL was 16.63±0.53 and 22.3±0.88 days in 2- and 3- wave cycles. One buffalo in Group 2 did not respond to injection of a single dose of PGF2α, while the other 4 responded. On the day of injection the diameter of the CL was 1.90±0.11 cm and that of dominant follicle was 0.97±0.07 cm. On day 2 after injection the follicle diameter was 1.4±0.09 cm and the preovulatory follicle on days 3-4 was 1.5±0.03 cm. The regressing CL diameter was 1.3±0.07 cm and progesterone level decreased from 6.27±0.82 ng/mL on day 0, to 0.13±0.06 ng/mL on days 3-4 post injection. Estradiol levels were increased from 5.40±1.2 pg/mL on day 0, to 15.09±1.97 pg/mL on day 3-4 post injection. After injection of the first dose of PGF2α, in group 3 the maximum follicle diameter was 1.10±0.04 cm on day 6, then started to regress (0.60±0.04 cm on days 13-17 after injection. In the 2nd wave, the ovulatory follicle showed marked increase from day 2 (0.34±0.01 cm till days 13-17 (1.33±0.08 cm. The diameter of CL increased from 1.53

    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. 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). 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 (pweaned buffalo calves compared to other animals. There is no association between stress indices (cortisol level and neutrophil to lymphocyte ratio) and growth rate. 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 characters of growth suggest that IGF-1 is a reliable indicator for assessing metabolic status of individual calves.

    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.

    The prevalence of and possible risk factors for tuberculosis were studied in water buffalo from Pará, Brazil. In this study, 3,917 pregnant and nonpregnant female Murrah and Mediterranean buffaloes were studied; 2,089 originated from Marajó Island, and 1,108 were from the mainland. The comparative cervical tuberculin test was used as a diagnostic test for tuberculosis in these animals. The prevalence of positive buffaloes was 3.5 % (100/2,809) on Marajó Island and 7.2 % (80/1,108) on the mainland. The municipalities with the highest tuberculosis prevalence rates in animals were Ipixuna do Pará (10.1 %), Marapanim (9.8 %), Chaves (9.4 %), Paragominas (8.6 %), and Cachoeira do Arari (6.7 %). The tuberculosis prevalence was not significantly different between the Murrah (4.3 %) and Mediterranean (4.8 %) breeds or between pregnant (5 %) and nonpregnant (4.3 %) buffaloes. Tuberculosis was detected in water buffaloes from Pará, Brazil; the mainland buffalo exhibited the highest tuberculosis prevalence. These results indicate that this disease is dangerous to public health and buffalo farming in Pará.

    Full Text Available Generation of methane from animal dung through AD (Anaerobic Digestion is the most feasible way to get energy from it. Pakistan has about 70 million heads of cattle and buffalos, and about 90 million heads of sheep and goats. The dung from these animals can overcome the energy crisis and can fulfill the future energy demands of Pakistan. In present study, buffalo dung is used as the substrate for anaerobic digestion process, whereas the production of methane was analyzed as the function of buffalo dung to water ratio. Six batch reactors with different buffalo dung to water ratios were incubated in the AMPTS (Automatic Methane Potential Test Setup for 51 days. The highest methane production was observed from the buffalo dung to water ratio of 2.0 i.e. 226.4 NmL/gVS loss , followed by 198.6 NmL/ gVS loss from the buffalo dung to the water ratio of 1.0. The suitable hydraulic retention time of the anaerobic digester treating buffalo dung was observed as 20 days

    Full Text Available Prevalence of endo and ecto-parasites in cows and buffaloes were investigated in Quetta city, Pakistan. A total of 396 livers and gall bladders of cows and 340 of buffaloes were selected randomly. Overall prevalence of liver parasites in cows and buffaloes was 45.70 and 37.05%, respectively. The species found in livers of cows were: Fasciola hepatica (16.16%, Fasciola gigantica (12.37%, Paramphistomum explanatum (7.82% and mixed infections (9.34%. The corresponding values for buffaloes were 11.47, 13.52, 5.58 and 6.47%. For ecto-parasites, out of 404 cows and 386 buffaloes examined, 28.96 and 25.64% respectively gave positive results for ecto-parasites. The prevalence of ticks, lice, mites and mixed infection was found to be 10.14, 7.17, 5.19 and 6.43%, respectively in cows and 6.99, 9.84, 4.92 and 3.88% respectively in buffaloes. It was concluded that the prevalence of endo and ecto-parasites in cows was higher than in buffaloes due to differences in feeding habits and hygienic habitats of the two species.

    Full Text Available 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.

    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 (p<0.001). In addition, one buffalo lymphoma sample was negative in both PCR assays used in this study. BLV was not detected in buffaloes from the Amazon 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.

    Full Text Available Background and Aim: Mastitis is a serious disease of dairy animals causing great economic losses due to a reduction in milk yield as well as lowering its nutritive value. The application of somatic cell count (SCC and alkaline phosphatase activity in the milk for diagnosis of mastitis in buffalo is not well documented. Therefore, the present study was conducted to observe the SCC and alkaline phosphatase activity for evaluation of mastitis in buffalo. Materials and Methods: Milk samples of forty apparently healthy lactating buffaloes were selected and categorized into five different groups viz. normal buffaloes, buffaloes with subclinical mastitis with CMT positive milk samples (+1 Grade, (+2 Grade, (+3 Grade, and buffaloes with clinical mastitis with 8 animals in each group. The milk samples were analyzed for SCC and alkaline phosphatase activity. Results: The levels of SCC (×105 cells/ml and alkaline phosphatase (U/L in different groups were viz. normal (3.21±0.179, 16.48±1.432, subclinical mastitis with CMT positive milk samples with +1 Grade (4.21±0.138, 28.11±1.013, with +2 Grade (6.34±0.183, 34.50±1.034, with +3 Grade (7.96±0.213, 37.73±0.737 and buffaloes with clinical mastitis (10.21±0.220, 42.37±0.907 respectively, indicating an increasing trend in the values and the difference observed among various group was statistically significant. Conclusion: In conclusion, the results of the present study indicate that the concentration of milk SCC and alkaline phosphatase activity was higher in the milk of buffaloes with mastitis than in the milk of normal buffaloes.

    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.

    2001-07-01

    Full Text Available Data on 2704 lactations of 993 Nili-Ravi buffaloes were analyzed to investigate the extent and behavior of short and complete lactations. Lactation milk yield up to 44 weeks was used and lactations with less .than eight weeks of duration were excluded. Fifty nine percent of the lactation records were shorter than 44 weeks. When minimum lactation length was required to be 26 weeks, 11% of lactations did not meet this criterion. Among 2107 lactations of< 308 days duration, reasons of drying were known for 534 lactations (25%. Out of these 31% had mastitis, 16% were shorter because buffaloes had been auctioned while she was in milk, 13% had bad temperament .while the other 40% were short because of reproductive problems and other reasons such as death of calf, old age, disease etc. Lactation curves were different for first and later parities with lactations of different duration. About 10% of lactations were atypical, with first calvers having the highest frequency. Improvement in data recording will help explore lactation length problems mote precisely in future.

    Full Text Available Anoa, which is the endemic animal in Indonesia, its population is unevitably decreasing, therefore anoa included in the list of endangered species by International Union for Conservation of Nature (IUCN. The experiment was aimed to apply the artificial insemination (AI technique for anoa and to examine their parturition behavior. The experiment involved 2 males and 5 females anoa at Taman Safari Indonesia Bogor. Semen was collected by electroejaculator, then evaluated and diluted in Tris-egg yolk extender. The anesthetized estrous females were inseminated intracervically with extended semen (100x106 sperm/1.0 mL. Females which did not show estrous signs during 2-3 cycles after AI were predicted pregnant, and therefore confirmed by ultrasonography. As a comparison, another predicted-pregnant female after natural mating was scanned. The results showed that intracervical AI resulted pregnancy in one female, and the gestation period of anoa was ranged from 313 d (AI to 324 d (natural mating. There were three stages of parturition process was observed: Stage 1 was characterized by the abdominal contraction and amniotic membrane rupture, Stage 2 was characterized by the fetal expulsions, and Stage 3 was characterized by the placental expulsions and ingestion of placenta by the dam. The duration of each stage of parturition was 6-8 h (stage 1, 30-60 min (stage 2, and 15-180 min (stage 3. It is concluded that AI technique was applicable to anoa in captivity, and the parturation behavior of anoa was comparable to buffalo and cattle. However, the fetal delivery occurred when the dam was in standing position and the dam ingested the placenta.

    Full Text Available The population of anoa, which is an endemic fauna to Indonesia, was getting decrease caused by the illegal hunting and deforestation. Anoa is included in endangered species by IUCN, and Appendix I by CITES. The experiment aimed to characterize the seminal plasma contents and to cryopreserve the anoa semen for artificial insemination application in captivity. The experiment was carried out in Taman Safari Indonesia (Bogor. Semen was collected from 2 anesthetized males (4-10 years by electroejaculation. Seminal plasma gained by centrifugation of ejaculate (3000 rpm, 20 minutes, and then was evaluated the biochemical contents. Other ejaculates were evaluated macroscopically and microscopically, and then extended in Tris and Na-citrate media to a total concentration of 100 billion cells mL-1. Extended semen was stored at 4oC, and evaluated the motility and viability every 12 h. Frozen semen was made in Tris medium added with 5% of glycerol. The seminal plasma of anoa contained total lipid, Na, Ca and Mg higher than the buffalo, but its total protein, K and Cl were lower. Electrophoresis of seminal plasma using by SDS-PAGE method showed 10 bands of proteins (17-148 kDa. The motility and viability of chilled-extended semen in Tris and Na-citrate media were not significantly different (P > 0.05 during 72 h of evaluation. Extended semen in both of media may applicable for AI program for 24-48 h. Post thawing motility of frozen semen was still low, 26.00 ± 9.62%. Therefore, it is necessary to improve each stages of semen processing, so the motility will increased and resulted high pregnancy in AI program.

    2005-09-01

    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.

    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

    Full Text Available The purpose of this study was to control follicular growth using norgestomet implant along with steroids in river buffalo. The estrous cycle of females (n=12 was synchronized with two prostaglandin F2α analogue (PG; 15 mg, IM; Prosolvin®, Intervet, Holland injections, 14 days apart. On Day 6 or 7 of the ensuing cycle (Day 0 of experiment, females received norgestomet implant (NORG; 3 mg; Crestar®, Intervet, Holland. Females received PG on Days 0, 1 and 13. On Day 5, females assigned randomly into three groups (n=4 in each group. The females of the 1st and 2nd groups received 2 and 5 mg estradiol benzoate (EB; Aburaihan, Iran, respectively, in association with 100mg of progesterone (PROG; Aburaihan, Iran. Group three females were did not receive any further treatment (control. The implant was removed on Day 14. Daily Ultrasonography was conducted to identify ovarian structures. In control group females, ovarian dominant follicle became persistent (PDF and ovulation of PDF occurred within 64±8 hours after implant removal. In steroid groups, the injection of 2mg (Group 1 and 5mg (Group 2 EB along with 100mg PROG caused regression of PDF in 50% and 100% of treated females, respectively. The time of follicular regression (2mg: 5.5±1.5 days; 5mg: 5.5±0.87 days and the emergence of the new follicular wave (2mg: 8 day; 5mg: 7.5±0.5 days were not different between steroid treated groups (P>0.05. None of the treated animals in these groups had ovulation during 5 days after implant removal. In conclusion, 5 mg EB in association with 100 mg PROG results in a consistent follicle regression followed by an emergence of new follicular wave. However, steroids along with NORG may not be advised in river buffalo due to the ovulation failure after implant removal. This might be due to the high sensitivity of river buffalo to steroid treatments.

    Full Text Available Strains of live Saccharomyces cerevisiae yeast have exhibited probiotic effects in ruminants. This study investigated the effects of the dietary yeast supplement, S. cerevisiae (Yea-Sacc1026, on primiparous (PP and multiparous (MP Egyptian buffaloes in early to mid-lactation. Lactating buffaloes were fed either a basal total mixed ration (TMR, control; 4 PP and 8 MP or the basal TMR plus 10 g Yea-Sacc1026 per buffalo cow per day (yeast; 4 PP and 8 MP. The feeds were given from 15 days prepartum to 180 days postpartum. Feed intake, body weight, and milk yields (MY were recorded, and milk and blood samples were collected for analyses. Feces were collected from days 45 to 47 during early lactation and from days 90 to 92 during mid-lactation to determine apparent digestibility of dry matter (DM, organic matter (OM, crude protein (CP and crude fiber (CF. Energy corrected milk yield (ECM, feed conversion, and energy and nitrogen conversion efficiency were calculated. Yeast treated MP buffaloes consumed more DM (P ≤ 0.041 and CP than the untreated control group. Apparent digestibility of DM and OM were significantly greater at mid-lactation for treated versus control group (P = 0.001. Crude fiber digestibility was greater in MP than in PP buffaloes (P = 0.049, and yeast supplemented MP cows had a greater CF digestibility than control MP buffaloes at mid-lactation (P = 0.010. Total blood lipids decreased after yeast supplementation (P = 0.029. Milk yields, ECM, fat and protein yields increased for yeast treated MP buffaloes (P ≤ 0.039. The study concluded that the response to yeast supplementation in buffalo cows is parity dependent. Multiparous buffaloes respond to yeast supplementation with an increased DM intake and CF digestibility without significant weight gains, allowing a greater ECM yield with less fat mobilization. Supplementing buffaloes with yeast culture may increase milk production in early lactation and results in a

    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 The objective of this study was to evaluate the effect of passive transfer status, determined by measuring serum IgG concentration 24 hours after parturition, on growth performance in buffalo calves fed milk replacer or allowed to nurse the dam during the first month of life. Experiment consisted of 24 healthy buffalo calves from birth to 30 days old. Significant quadratic associations were detected between serum IgG concentration 24 hours after birth and day-30 weight (P < 0.05; R2 = 0.62 and between serum IgG concentration 24 hours after birth and the mean daily gain from birth to day 30 (P < 0.01; R2 = 0.74 in buffalo calves allowed to nurse the dam. No significant association was detected between serum IgG concentration 24 hours after birth and measures of growth performance in buffalo calves fed milk replacer. Results indicated that passive transfer status, determined as serum IgG concentration 24 hours after birth, was a significant source of variation in growth performance when buffalo calves nursed the dam. Maximizing passive transfer of immunity by allowing buffalo calves to nurse the dam increased the growth performance during the first month of life.

    Helicobacter pylori infection in humans is one of the most common infections worldwide. However, the origin and transmission of this bacterium has not been clearly explained. One of the suggested theories is transmission via raw milk from animals to human beings. This study was conducted to determine the prevalence rate of H. pylori in bulk milk samples from dairy bovine, buffalo, camel, ovine, and caprine herds in Iran. In the present study, 447 bulk milk samples from 230 dairy bovine, buffalo, camel, ovine, and caprine herds were collected in four provinces and tested for H. pylori by cultural method and polymerase chain reaction (PCR) for the detection of the ureC (glmM) gene. The animals whose milk samples collected for this study were clinically healthy. Using the cultural method, three of 447 milk samples (0.67%), including two sheep (2.2%) and one buffalo (1.6%) milk samples, were found to be contaminated with H. pylori. H. pylori ureC gene was detected in 56 (12.5%) of milk samples, including 19 cow (14.1%), 11 sheep (12.2%), nine goat (8.7%), two camel (3.6%), and 15 buffalo (23.4%) milk samples. Using PCR method, there were significant differences (pmilk samples collected from different species. The present study is the first report of the isolation of H. pylori from raw sheep and buffalo milk in Iran and the first demonstration of H. pylori DNA in camel and buffalo milk.

    Milk is a natural nutraceutical produced by mammals. The nanovesicles of milk play a role in horizontal gene transfer and confer health-benefits to milk consumers. These nanovesicles contain miRNA, mRNA, and proteins which mediate the intercellular communication. In this work, we isolated and characterized the buffalo milk-derived nanovesicles by dynamic light scattering (DLS), nanoparticle tracking analysis (NTA), scanning electron microscopy (SEM), Western probing, and Fourier transform infrared (FTIR) spectroscopy. The DLS data suggested a bimodal size distribution with one mode near 50 nm and the other around 200 nm for the nanovesicles. The NTA and SEM data also supported the size of nanovesicles within a range of 50-200 nm. The FTIR measurements of nanovesicles identified some prominent absorption bands attributable to the proteins (1300-1700 cm(-1), amide A and amide B bands), lipids (2800-3100 cm(-1)), polysaccharides, and nucleic acids (900-1200 cm(-1)). The comparative expression profiles of immune miRNA signatures (miR-15b, miR-21, miR-27b, miR-125b, miR-155, and miR-500) in nanovesicles isolated from milk, serum, and urine revealed that these miRNAs are present abundantly (P < 0.05) in milk-derived nanovesicles. Milk miRNAs (miR-21 and 500) that were also found stable under different household storage conditions indicated that these could be biologically available to milk consumers. Overall, nanovesicles are a new class of bioactive compounds from buffalo milk with high proportion of stable immune miRNAs compared to urine and plasma of same animals.

    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.

    2012-01-01

    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.

    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 (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 The in vitro gas production technique (IVGPT, Theodorou et al., 1994 requires a rumen liquor (RL inoculum, as the other methods utilising a microbial fermentation approach to feedstuff evaluation. However, the RL is collected either from animals fitted with rumen cannula or at slaughtering. This raises a number of practical, economical and ethical problems, thus several studies have been carried out to test alternative inocula. To this aim faeces (FA have been demonstrated to have high potentiality for the Tilley and Terry (1963 technique (El Saher et al., 1987; Akther et al., 1999; Cone et al., 2002. Mauricio et al. (2001, evaluating the forages fermentative characteristics by IVGPT, found lower potential gas production and longer lag times for bovine FA compared to RL as inoculum. Aim of present paper was to compare buffalo RL and FA as inoculum for IVGPT.

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.

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 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.

    The epidemiological aspects of Theileria orientalis in Pakistan are unknown; therefore, investigations using sensitive and precise molecular techniques are required. This study reports the first molecular characterisation of T. orientalis detected from imported (Bos taurus) and native cattle (Bos indicus×Bos taurus) and buffaloes (Bubalus bubalis) selected from four districts of Punjab, Pakistan. DNA samples from blood (n=246) were extracted and tested using conventional PCR utilising the major piroplasm surface protein (MPSP) gene and multiplexed tandem PCR (MT-PCR). Theileria orientalis DNA was detected (15%; 22/147) only in imported cattle by conventional PCR, whereas 24.5% (36/147), 6% (3/50) and 6.1% (3/49) of the imported cattle and native Pakistani cattle and buffaloes, respectively were test-positive for T. orientalis using MT-PCR. Using MT-PCR, the prevalence of T. orientalis was significantly higher (PPakistan, and highlights the need for future studies to understand the spread of transboundary animal diseases.

    Fraudulent mislabelling of processed meat products on a global scale that cannot be detected using conventional techniques necessitates sensitive, robust and accurate methods of meat authentication to ensure food safety and public health. In the present study, we developed an in-gel (two-dimensional gel electrophoresis, 2DE) and OFFGEL-based proteomic method for authenticating raw and cooked water buffalo (Bubalus bubalis), sheep (Ovis aries) and goat (Caprus hircus) meat and their mixes. The matrix-assisted liquid desorption/ionization time-of-flight mass spectrometric analysis of proteins separated using 2DE or OFFGEL electrophoresis delineated species-specific peptide biomarkers derived from myosin light chain 1 and 2 (MLC1 and MLC2) of buffalo-sheep-goat meat mix in definite proportions at 98:1:1, 99:0.5:0.5 and 99.8:0.1:0.1 that were found stable to resist thermal processing. In-gel and OFFGEL-based proteomic approaches are efficient in authenticating meat mixes spiked at minimum 1.0% and 0.1% levels, respectively, in triple meat mix for both raw and cooked samples. The study demonstrated that authentication of meat from a complex mix of three closely related species requires identification of more than one species-specific peptide due to close similarity between their amino acid sequences. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    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.

    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.

    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. Copyright © 2016. Published by Elsevier Ireland Ltd.

    The objectives of the present study were to determine the relationship between bacteriological findings, clinical signs and histopathological changes in postpartum metritis. Evaluation of the treatment efficiency of using systemic or intra-uterine infusion of antibiotics with some hormonal preparations for the treatment of postpartum metritis. Data were collected from 50 buffalo cows with history of calving of more than 1 month. All buffaloes were subjected to detailed clinical examination including external inspection, vaginoscopy and transrectal palpation of the cervix, uterus and ovaries. Swabs for bacteriology and biopsies for histopathology were collected from uterine lumen from each buffalo included in the present study. Bacteria identified using API systems following aerobic and anaerobic cultures. Vaginal mucus scored for character, odour and estimation of polymorphonuclear cells (PMNs). Treatment conducted using oxytetracycline in local intrauterine infusion or systemically with hormonal treatment including prostaglandin F2 alpha (PGF2 alpha) and oestradiol benzoate. Results revealed that the most predisposing factor for postpartum uterine infection was retained placenta and toxic puerperal metritis. The most prevalent bacteria in uterine lumen were Escherichia coli, Archanobacterium pyogenes, Bacteroides fragilis and Fusobacterium necrophorum the most prevalent bacteria in buffaloes with postpartum metritis. A. pyogenes and F. necrophorum were an important pathogens causing severe uterine inflammation as found in histopathological examinations. Buffaloes with postpartum metritis showed good clinical cure when oxytetracycline injected systemically with PGF2 alpha. Intrauterine infusion of oxytetracycline had no advantage for the treatment of uterine infection in buffalo cows with postpartum metritis. PGF2 alpha improved clinical cure of buffaloes with postpartum metritis.

    The aim of this study was to define the microbiota of water buffalo milk during sub-clinical and clinical mastitis, as compared to healthy status, by using high-throughput sequencing of the 16S rRNA gene. A total of 137 quarter samples were included in the experimental design: 27 samples derived from healthy, culture negative quarters, with a Somatic Cell Count (SCC) of less than 200,000 cells/ml; 27 samples from quarters with clinical mastitis; 83 samples were collected from quarters with subclinical mastitis, with a SCC number greater of 200,000 cells/ml and/or culture positive for udder pathogens, without clinical signs of mastitis. Bacterial DNA was purified and the 16S rRNA genes were individually amplified and sequenced. Significant differences were found in milk samples from healthy quarters and those with sub-clinical and clinical mastitis. The microbiota diversity of milk from healthy quarters was richer as compared to samples with sub-clinical mastitis, whose microbiota diversity was in turn richer as compared to those from clinical mastitis. The core microbiota of water buffalo milk, defined as the asset of microorganisms shared by all healthy milk samples, includes 15 genera, namely Micrococcus, Propionibacterium, 5-7N15, Solibacillus, Staphylococcus, Aerococcus, Facklamia, Trichococcus, Turicibacter, 02d06, SMB53, Clostridium, Acinetobacter, Psychrobacter and Pseudomonas. Only two genera (Acinetobacter and Pseudomonas) were present in all the samples from sub-clinical mastitis, and no genus was shared across all in clinical mastitis milk samples. The presence of mastitis was found to be related to the change in the relative abundance of genera, such as Psychrobacter, whose relative abundance decreased from 16.26% in the milk samples from healthy quarters to 3.2% in clinical mastitis. Other genera, such as SMB53 and Solibacillus, were decreased as well. Discriminant analysis presents the evidence that the microbial community of healthy and clinical

    Full Text Available Influence of -110, +110, +220 and +330 mEq/kg dry matter (DM of dietary cation anion difference (DCAD on performance of early lactating Nili Ravi buffaloes was examined in a randomized complete block design during summer. Four DCAD levels were randomly allotted to four groups, three buffaloes in each group. A linear increase in nutrients and water intakes were recorded with increasing the DCAD level. A significant increase in blood pH and HCO3 was noticed with increasing DCAD level. Serum (Na + K - (Cl + S increased linearly with increasing the DCAD level while high serum chloride was noticed in buffaloes fed -110 DCAD diet. The serum calcium increased significantly with decreasing the DCAD level while serum magnesium and phosphorus remained unaffected. Urine pH increased significantly with increasing DCAD level. Higher serum cortisol was notices in buffaloes fed -110 than those fed +330 mEq/kg. A linear increase in milk yield was also noticed with increasing the DCAD level. Milk fat% increased significantly with increasing the DCAD while all other milk constituents remained unaltered. Buffaloes fed high DCAD diets had higher conception rate and less services per conception than those fed low DCAD diets.

    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 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.

    The major aim of this study was to compare the morphology and activity of rumen protozoa of Khuzestan water buffalo and Holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. Rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. To separate rumen protozoa, antibiotic solution and fungicides were added to rumen fluid. The results of present experiment indicated that the neutral detergent fiber (NDF; 7.8 vs. 1.69%) and acid detergent fiber (ADF; 6.24 vs. 3.24%) digestibility of steam treated sugarcane pith by rumen protozoal population of Khuzestan buffalo was higher than those of cow (p cow (p cow (p cow (3.68 × 10(5) vs. 2.18 × 10(5) mL(-1) of rumen content) (p cow (41.27 vs. 35.7% of total rumen protozoa, respectively). Percentage of Entodinium, Epidinium, Ophryoscolex and Isotricha in cow was more than those of buffalo. Therefore, in the same diet, protozoa and total rumen micro-organisms of Khuzestan water buffalo have higher digestion activity compared to Holstein cow.

    Full Text Available The objective of this study was to determine if B. abortus rough mutant strain RB51 is eliminated in Buffalo milk. Five milk buffaloes were inoculated with the triple of the recommended calfhood dose (3.0 – 10.2 x 1010 cfu/ml of B. abortus RB51 strain by subcutaneous route in the right axillary region. Milk samples were taken aseptically on a daily basis for the first 30 days and weekly for the second and third months. The samples were inoculated on Brucella Medium Base (BMB (Oxoid and Rifampin Brucellae Medium (RBM and incubated under 10% CO2 at 37°C for 10 days. The suspicious colonies were recultured in BMB and RBM. PCR analysis was also performed on milk samples. There were no isolations of bacteria with characteristics of Brucella from any of the milk samples collected during 90 days of the study. However Brucella RB51 DNA was detected on day 2 and 3 post vaccination in one buffalo cow and on day 21 post vaccination in another buffalo cow. It was concluded that the strain used at this dose wasn’t eliminated by milk in Buffaloes inoculated during lactation, however PCR positive results underline the necessity of milk pasteurization in order to minimize food-chain exposure.

    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.

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 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.

    Haemorrhagic septicaemia (HS) is an acute septicaemic disease of buffalo and cattle caused by Pasteurella multocida B:2 and E:2. Field outbreaks of HS are known to result in localisation of bacteria in the tonsils of surviving buffalo, confirming that animals can become carriers and the role of respiratory tract in the transmission of the disease. This report describes additional sites of localisation of P. multocida B:2 in surviving buffalo following experimental induction of HS. Following P. multocida B:2 infection, all calves in group 1 and one calf in group 2 that was allowed to commingle with infected calves from group 1 were euthanised within 48 h. Pasteurella multocida B:2 was detected from the nasal and rectal swab samples on days 5 and 6 from the remaining calves in group 2. The first injection of dexamethasone into the carrier animals resulted in reemergence in samples from the nose, rectum and vagina. However, subsequent dexamethasone injections failed to re-activate P. multocida B:2. When surviving carrier calves in group 2 were euthanised at the end of the experiment, P. multocida B:2 was detected in the lungs and various organs of the respiratory, gastrointestinal and urinary tracts. Commingling naive buffalo calves with calves acutely infected with P. multocida B:2 resulted in carriers among surviving buffalo. Pasteurella was found in various organs of the respiratory, gastrointestinal and urinary tracts, suggesting their role in the pathogenesis of HS.

    Full Text Available A retrospective study of the epidemiological and clinic-pathological aspects of cattle and buffaloes with degenerative joint disease (DJD was conducted in the state of Pará, Brazil. From 1999 to 2014, eleven cattle and 24 buffaloes were evaluated. All the treated animals with suspected DJD underwent a clinical examination of the musculoskeletal system. In seven cattle and eight buffaloes with clinical signs of the disease postmortem examination was performed. The common clinical signs observed in both species were chronic lameness, stiff gait, postural changes, audible crackles in the affected limb, prolonged recumbency, difficulty in getting up and progressive weight loss. The lesions observed at necropsy were: irregular articular surfaces, erosion of the articular cartilage and the underlying bone tissue, and proliferation of the periarticular bone tissue with formation of osteophytes. The most affected joints in cattle and buffaloes wereof the hind limb. In buffaloes, the main predisposing factor to the onset of DJD was phosphorus deficiency. In cattle, defects of the anatomical conformation of the hind limbs, chronic trauma due to the activities performed, such as semen collection, and advanced age possibly contributed to the emergence of the disease.

    Improper or delayed pregnancy diagnosis has significant impact over animal production, particularly in buffaloes which inherently suffer from several reproductive inefficiencies. Thus the present study has undertaken to identify serum protein markers pertaining to early pregnancy diagnosis in buffaloes. Serum samples were collected from 10 pregnant Murrah Buffalo heifers at weekly intervals from days 0-35 post-artificial insemination and from 12 inseminated non-pregnant cyclic buffalo heifers on days 0, 7, 14 and 21. Two-dimensional gel electrophoresis and densitometric analysis revealed the presence of five protein spots showing average density fold change of ≥4 during early pregnancy. Mass spectrometry analysis identified these up-regulated proteins as anti-testosterone antibody light chain, apolipoprotein A-II precursor, serum amyloid A, cytokeratin type II, component IV isoform 1, which are have established roles in embryogenesis, but over-expression of the fifth identified protein immunoglobulin lambda light chain in pregnancy has been elucidated as a novel finding in the current study. Further, with bioinformatics analysis, potential antigenic B-cell epitopes were predicted for all these five proteins. An antibody cocktail-based approach involving antibodies against all these five up-regulated entire proteins or their epitopes could be developed for early detection of pregnancy in buffaloes. © 2016 Japanese Society of Animal Science. © 2016 Japanese Society of Animal Science.

    The study aimed to develop new and more specific thermal comfort indices for buffaloes reared in the Amazon region. Twenty female Murrah buffaloes were studied for a year. The animals were fed in pasture with drinking water and mineral supplementation ad libitum. The following parameters were measured twice a week in the morning (7 AM) and afternoon (1 PM): air temperature (AT), relative air humidity (RH), dew point temperature (DPT), wet bulb temperature (WBT), black globe temperature (BGT), rectal temperature (RT), respiratory rate (RR), and body surface temperature (BST). The temperature and humidity index (THI), globe temperature and humidity index (GTHI), Benezra's comfort index (BTCI), and Ibéria's heat tolerance index (IHTI) were calculated so they could be compared to the new indices. Multivariate regression analyses were carried out using the canonical correlation model, and all indices were correlated with the physiological and climatic variables. Three pairs of indices (general, effective, and practical) were determined comprising the buffalo comfort climatic condition index (BCCCI) and the buffalo environmental comfort index (BECI). The indices were validated and a great agreement was found among the BCCCIs (general, effective, and practical), with 98.3 % between general and effective a.nd 92.6 % between general and practical. A significant correlation ( P < 0.01) was found between the new indices and the physiological and climatic variables, which indicated that these may be used in pairs to diagnose thermal stress in buffaloes reared in the Amazon.

    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 American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on human spirits and relations and how it is contradicted in different ways through the analysis of his brilliant play, American Buffalo by David Mamet. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world. This article indicates how capitalism inculcates ideologies in the mind of individuals in order to facilitate the exploiting process and unquestioning subordination. Ragged individualism, as one of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life. On the other hand, this individualism, as an ideology, is sustained by other capitalist ideologies such as advertising, consumerism and emulation. It will also be discussed that monetary interests are all one seeks in a highly competitive atmosphere and nothing is privileged over business ethics. In brief, this reading of the play tries to illuminate that we live in a dream-like world of ideologies that block logical thinking and forge our relationship with our real existence through less suspected ways.

    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

    The effect of addition of different decorticated legume flours, viz., soya bean, bengal gram, green gram and black gram, on the quality of buffalo meat burger was studied. The burgers consisted of optimized quantities of roasted or unroasted legume flour, spices and common salt. Inclusion of roasted black gram flour registered the highest yield of 95.7%, lowest shrinkage of 5% and lowest fat absorption of 26.6% on frying. Protein content of 18-20% was highest in the soya flour formulation. Free fatty acid (FFA) values (as% oleic) increased from 14.3 to 17.3 in freshly prepared samples (before frying) to 16.0-19.4 in 4 m frozen (-16±2 °C) stored samples and fried samples had about 25% lower FFA values. Formulations with roasted flours registered lower thiobarbituric acid (TBA) values (mg malonaldehyde/kg sample) of 0.6-1.5 as against 0.6-2.1 for unroasted flours before frying. The burgers prepared with any of these binders were organoleptically acceptable even after storage at -16±2 °C for 4 months., However, the burger with black gram dhal (dehulled split legume) flour had better sensory quality attributes compared to other legumes.

    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.

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.

    Full Text Available Brucellosis is a zoonotic disease of global importance infecting humans, domestic animals, and wildlife. Little is known about the epidemiology and persistence of brucellosis in wildlife in Southern Africa, particularly in Botswana.Archived wildlife samples from Botswana (1995-2000 were screened with the Rose Bengal Test (RBT and fluorescence polarization assay (FPA and included the African buffalo (247, bushbuck (1, eland (5, elephant (25, gemsbok (1, giraffe (9, hartebeest (12, impala (171, kudu (27, red lechwe (10, reedbuck (1, rhino (2, springbok (5, steenbok (2, warthog (24, waterbuck (1, wildebeest (33, honey badger (1, lion (43, and zebra (21.

Seropositive buffalo were widely distributed across the buffalo range where cattle density was low. Human infections were reported in low numbers with most infections (46% occurring in children (<14 years old and no cases were reported among people working in the agricultural sector.Low seroprevalence of brucellosis in Botswana buffalo in a previous study in 1974 and again in this survey suggests an endemic status of the disease in this species. Buffalo, a preferred source of bush meat, is utilized both legally and illegally in Botswana. Household meat processing practices can provide widespread pathogen exposure risk to family members and the community, identifying an important source of zoonotic pathogen transmission potential. Although brucellosis may be controlled in livestock populations, public health officials need to be alert to the possibility of human infections arising from the use of bush meat. This study illustrates the need for a unified approach in infectious disease research that includes consideration of both domestic and wildlife sources of infection in determining public health risks from

    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. © 2014 Blackwell Verlag GmbH.

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.

    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.

    Full Text Available This study was aimed to detect and record the clinical and ultrasonographic findings of the different complications resulted from the foreign bodies lodged in the compound stomach of cattle and buffaloes. A total of 105 animals (37 cattle and 68 buffaloes were subjected to study. Based on the clinical and ultrasonographic examination, animals were classified into; acute local reticuloperitonitis (ALRP (15 cattle and 28 buffaloes, chronic local reticuloperitonitis (CLRP (6 cattle and 14 buffaloes, acute diffuse reticuloperitonitis (ADRP (5 cattle and 3buffaloes, reticular abscesses (RA (4 cattle and 7 buffaloes, traumatic pericarditis (TP (6 cattle and16 buffaloes and liver abscess (one cattle. Results revealed that ALRP represented the highest percentage of 40.5% in cattle and 41.2 % in buffalos between the different complications of TRP. TP represented the second complications of higher incidence (16.2% in cows and 23.5% in buffalos. Liver abscess represented the lowest percentage (2.8% and was recorded in cows only. The pregnant animals were affected more than the non pregnant. Clinical findings represented in systemic reaction and pain tests were commonly encountered in TRP and its complications. Some of the affected animals were negatively respond to metal detector test. Results of the present study indicated that the ultrasonographic examination provide a specific echogenic pattern for the different complications of TRP. It was concluded that, clinical examination only is not efficient to give accurate diagnosis of foreign body lodged in the reticulum and rumen and their complications. Ultrasonography is a safe, non invasive diagnostic confirmatory method that could be used for early detection of such conditions.

    Countries of the Mediterranean area are characterized by production of artisanal cheeses, obtained from goat, sheep, cow and buffalo raw milk. The numbers and species of yeasts in the different cheeses are variable, but some species are more frequently detected than others. Kluyveromyces marxianus, K. lactis with their anamorph, Candida kefir, Debaryomyces hansenii and C. famata, C. colliculosa and C. catenulata are dominant species in several cheeses. However, Saccharomyces cerevisiae is often detected in pasta filata cheeses, such as Water Buffalo Mozzarella (WBM) or Cacio Cavallo Podolico. Recently, a comprehensive study of yeasts isolated from Mozzarella cheese produced in Basilicata (Southern Italy) has been carried out. The study has focused on lactose and/or galactose fermenting species (Kluyveromyces and Saccharomyces) to evaluate their role on the functional and sensory properties of the product. End products in milk were evaluated and the biodiversity in terms of production of sulphur dioxide, higher alcohols, ethyl acetate, and acetaldehyde was studied. In particular, S. cerevisiae strains from Water Buffalo Mozzarella cheese, compared to strains isolated from different habitats, such as wine, exhibited considerable difference in the production of some volatile compounds. The diversity observed could be related to the particular microhabitat of S. cerevisiae occurring in whey cheese of water buffalo milk.

    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 Flavour is an important consumer attractive that directly influences the success of food products on the market. The determination of odorous molecules and their identification allows to useful knowledge for producers to valorise their own products. Buffalo meat has a different chemical composition from pork and beef and requires some cautions in cooking and processing. This work aims at the identification of volatile molecules responsible for flavours in river buffalo meat. The determination was carried out by solid phase micro-extraction (SPME technique and analysed by gas chromatography coupled to mass spectrometry (GC-MS. The most relevant results were the higher odorous impact of buffalo meat and the higher content of sulphide compounds responsible for wild aroma respect to pork and beef. These results were obtained comparing the total area of peaks detected in every chromatogram. We have also found significant differences concerning the contents of pentadecane, 1-hexanol-2 ethyl, butanoic acid, furano-2-penthyl. The origin of volatile organic compounds and their influence on the river buffalo aromas were discussed.

    Full Text Available This study describes the ultrastructural changes and distribution of P. multocida B:2 in the respiratory and gastrointestinal tracts of buffalo calves following oral exposure and compared with intratracheal exposure. Nine 8-month old buffalo calves were divided into 3 groups. At the start of the experiment, dexamethasone (1mg/kg was injected intramuscularly into buffaloes of all groups for three consecutive days. Then, calves of Group 1 were exposed orally to 50ml of the inoculum containing 109 colony-forming unit (CFU/mL of live P. multocida B:2. Calves of Group 2 were exposed intra-tracheal to the same inoculum while calves of Group 3 were exposed orally to PBS. Transient and mild clinical signs were observed in calves of Groups 1 and 2. Pasteurella multocida B:2 was isolated from the nasal mucosa for up to 5 days post-infection. Only calf that was killed at 48 h post-infection had P. multocida B:2 in both respiratory and gastro-intestinal tracts showing ultrastructural changes typical of acute cellular injury, with degeneration of endothelium and vascular walls. There were deciliation in the respiratory and microvilli degeneration in the gastrointestinal tracts. The study concludes that oral exposure may not play major role in the development of hemorrhagic septicemia. Nevertheless, the buffalo calf that succumbed to hemorrhagic septicemia carried P. multocida B:2 in the gastro-intestinal organs.

    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� product�s 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 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.

    Prevention of food fraud in the dairy field is a difficult issue for researchers, industries and policy makers, both for commercial and health reasons. Currently, no analytical method allows detection of the addition of bovine whey to water buffalo ricotta, so this fraudulent practice cannot be prevented. The authors' aim was to develop such a method. The conditions for extraction and purification of denatured ricotta whey proteins, which are unfolded and coagulated by heating during the production process, were optimized. The optimal composition of the polyacrylamide gel (pH range, type and concentration of chemical separator) was first evaluated and then the best conditions to perform the separation by isoelectric focusing were established. The performance of the method (precision, selectivity, robustness, sensibility) was determined. The method was shown to be reliable and robust for detection of the presence of bovine whey added to water buffalo Ricotta at percentages above 5% (v/v). The results suggest that the differences observed between bovine and water buffalo electrophoretic profiles are due to bovine β-lactoglobulin isoform A, which is never detected in water buffalo samples. © 2014 Society of Chemical Industry.

    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.

  16. Microsatellite loci isolation from river buffalo using enriched partial genomic libraries

    2010-02-01

    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.

    Skin injuries were assessed in 560 imported and local cattle and water buffaloes at two livestock markets in Bangladesh. The body of each animal was divided into 11 anatomical regions, and abrasions, lacerations, penetrations, ulcerations, bleeding, swelling, hyperkeratosis and scars were recorded for each region. Among the 560 animals studied, 501 were found to have at least one injury. The prevalence of skin injuries was 89 per cent, with 84 per cent of the cattle and 99 per cent of the water buffaloes having obvious skin injuries. The most common types of injury were abrasions that were found in 73 per cent of the animals, followed by scars (50 per cent), and lacerations (41 per cent). Buffaloes had more abrasions (95 per cent), lacerations (57 per cent), swelling (15 per cent) and hyperkeratosis (32 per cent) compared with cattle, whereas scars (60 per cent) were more common in cattle (Ptypes of injuries were present but in different proportions. The buttock region had a higher proportion of abrasions (36 per cent) followed by the hip, hindlimb and back regions. Penetration, ulceration, bleeding and swelling were present at lower frequencies in all regions. Causes for these injuries included rubbing against the inside wall of vehicles used for transportation and stock-handler abuse (59 per cent and 13 per cent, respectively). Buffaloes sustained more transport injuries than cattle, and the number of injuries was higher in imported than local animals.

Materials and Methods: A total number of 47 buffaloes were included in the study and divided into two groups: Healthy (n=10 and diseased groups (n=37. Diseased buffaloes were admitted to the Veterinary Teaching Hospital at Zagazig University, Egypt, with a history of anorexia, sudden, and severe reduction of milk production with no response to a previous medical treatment some animals had edema at the dewlap and congestion of the jugulars. These animals were subjected to clinical examination, evaluation by hemato-biochemical analysis including cardiac biomarkers and sonography. Results: The hemato-biochemical analysis revealed leukocytosis with a shift to left and hyperfibrinogenemia (indicating inflammation. Serum cardiac biomarkers including cardiac troponin I (cTnI, cTnT, nitric oxide, creatine kinase myocardial band, and lactic dehydrogenase enzyme were significantly increased in buffaloes with TP compared with control ones. Ultrasonographically, there were hypoechoic materials with echogenic fibrin interspersed in between the pericardial sac. Conclusions: The cardiac biomarkers may be considered a useful index in the early diagnosis of TP. Moreover, ultrasonography is an excellent tool for early prediction and diagnosis of such condition.

    To evaluate different levels of energy and protein for optimum growth of Murrah male buffalo calves, a growth trial (150 days) was conducted on 30 calves (body weight 202.5 ± 6.8 kg). Six diets were formulated to provide 90, 100 and 110% protein level and 90 and 110% energy level requirements for buffalo calves, derived from ICAR 2013 recommendations for buffaloes. The crude protein (CP) intake was increased with higher dietary CP, whereas no effect of energy levels or interaction between protein and energy was observed on CP intake. There were significant effects (P dietary CP, whereas the N retention was similar among all the groups distributed as per different energy or protein levels. The nutrient intake (protein or energy) per kg body weight (BW)(0.75) at various fortnight intervals was regressed linearly from the average daily gain (ADG) per kg BW(0.75). By setting the average daily gain at zero in the developed regression equation, a maintenance requirement was obtained, i.e. 133.1 kcal ME, 6.45 g CP and 3.95 g metabolizable protein (MP) per kg BW(0.75). Requirement for growth was 6.12 kcal ME, 0.46 g CP and 0.32 g MP per kg BW(0.75) per day. Metabolizable amino acid requirement was estimated from partitioning of MP intake and ADG. The ME requirements were lower, whereas the MP requirement of Murrah buffaloes was higher than ICAR (2013) recommendations.

    Full Text Available Aim: The present study was conducted on advanced pregnant buffaloes suffering from uterine torsion to assess the status of fetus and uterus by transabdominal ultrasonography, and the findings were compared with normal advanced pregnant buffaloes. Materials and Methods: The study was conducted on 20 clinical cases of uterine torsion and 20 normal advanced pregnant buffaloes (control group. 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.

    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.

    The present study was conducted on advanced pregnant buffaloes suffering from uterine torsion to assess the status of fetus and uterus by transabdominal ultrasonography, and the findings were compared with normal advanced pregnant buffaloes. The study was conducted on 20 clinical cases of uterine torsion and 20 normal advanced pregnant buffaloes (control group). 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. 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. 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.

    Characterization of molecular markers and the development of better assays for precise and rapid detection of domestic species are always in demand. This is particularly due to recent food scares and the crisis of biodiversity resulting from the huge ongoing illegal traffic of endangered species. The aim of this study was to develop a new and easy method for domestic species identification (river buffalo, cattle, sheep and goat) based on the analysis of a specific mitochondrial nucleotide sequence. For this reason, a specific fragment of Egyptian buffalo mitochondrial 16S rRNA gene (422 bp) was amplified by PCR using two universal primers. The sequence of this specific fragment is completely conserved between all tested Egyptian buffaloes and other river buffaloes in different places in the world. Also, the lengths of the homologous fragments were less by one nucleotide (421 bp) in case of goats and two nucleotides (420 bp) in case of both cattle and sheep. The detection of specific variable sites between investigated species within this fragment was sufficient to identify the biological origin of the samples. This was achieved by alignment between the unknown homologous sequence and the reference sequences deposited in GenBank database (accession numbers, FJ748599-FJ748607). Considering multiple alignment results between 16S rRNA homologous sequences obtained from GenBank database with the reference sequence, it was shown that definite nucleotides are specific for each of the four studied species of the family Bovidae. In addition, other nucleotides are detected which can allow discrimination between two groups of animals belonging to two subfamilies of family Bovidae, Group one (closely related species like cattle and buffalo, Subfamily Bovinae) and Group two (closely related species like sheep and goat, Subfamily Caprinae). This 16S DNA barcode character-based approach could be used to complement cytochrome c oxidase I (COI) in DNA barcoding. Also, it is a

    The transcriptome profiles were compared for buffalo embryos with normal growth and embryos with retarded growth on Day 25 after mating. Embryos with retarded growth on Day 25 after mating have a reduced likelihood of undergoing attachment to the uterine endometrium and establishing a pregnancy. Italian Mediterranean buffaloes were mated by AI and on Day 25 underwent trans-rectal ultrasonography to ascertain embryo development. Embryos with an embryonic width (EW)>2.7 mm were classed as normal embryos and embryos with an EW<2.7 mm were classed as retarded embryos. Three buffaloes with embryos of the largest EW (3.7, 3.7 and 3.9 mm) and three buffaloes with embryos of the smallest EW (1.5, 1.6 and 1.9 mm) were slaughtered on Day 27 to recover embryos for transcriptome analysis using a bovine custom designed oligo array. A total of 1,047 transcripts were differentially expressed between embryos with normal growth and embryos with retarded growth. Retarded embryos showed 773/1,047 (74%) transcripts that were down-regulated and 274/1,047 (26%) transcripts that were up-regulated relative to normal embryos; in silico analyses focused on 680/1,047 (65%) of the differentially expressed transcripts. The most altered transcripts observed in retarded embryos were associated with membrane structure and function and with metabolic and homeostasis maintenance functions. Other notable functions altered in retarded embryos were developmental processes and in particular nervous system differentiation and function. Specific biochemical pathways such as the complement cascade and coagulation were also altered in retarded embryos. It was concluded from the findings that buffalo embryos with retarded growth on Day 25 after mating show altered gene expression compared with normal embryos, and some de-regulated functions are associated with attachment to the uterine endometrium.

    1. Many studies have investigated why males and females segregate spatially in sexually dimorphic species. These studies have focused primarily on temperate zone ungulates in areas lacking intact predator communities, and few have directly assessed predation rates in different social environments. 2. Data on the movement, social affiliation, mortality and foraging of radio-collared African buffalo (Syncerus caffer) were collected from 2001-06 in the Kruger National Park, South Africa. 3. The vast majority of mortality events were due to lion (Panthera leo) predation, and the mortality hazard associated with being an adult male buffalo in a male-only 'bachelor' group was almost four times higher than for adult females in mixed herds. The mortality rates of adult males and females within mixed herds were not statistically different. Mortality sites of male and female buffalo were in areas of low visibility similar to those used by bachelor groups, while mixed herds tended to use more open habitats. 4. Males in bachelor groups ate similar or higher quality food (as indexed by percentage faecal nitrogen), and moved almost a third less distance per day compared with mixed herds. As a result, males in bachelor groups gained more body condition than did males in breeding herds. 5. Recent comparative analyses suggest the activity-budget hypothesis as a common underlying cause of social segregation. However, our intensive study, in an area with an intact predator community showed that male and female buffalo segregated by habitat and supported the predation-risk hypothesis. Male African buffalo appear to trade increased predation risk for additional energy gains in bachelor groups, which presumably leads to increased reproductive success. ?? 2008 The Authors.

    Full Text Available Ovine rinderpest or goat plague is an economically important and contagious viral disease of sheep and goats, caused by the Peste des petits ruminants virus (PPRV. Differences in susceptibility to goat plague among different breeds and water buffalo exist. The host innate immune system discriminates between pathogen associated molecular patterns and self antigens through surveillance receptors known as Toll like receptors (TLR. We investigated the role of TLR and cytokines in differential susceptibility of goat breeds and water buffalo to PPRV. We examined the replication of PPRV in peripheral blood mononuclear cells (PBMC of Indian domestic goats and water buffalo and demonstrated that the levels of TLR3 and TLR7 and downstream signalling molecules correlation with susceptibility vs resistance. Naturally susceptible goat breeds, Barbari and Tellichery, had dampened innate immune responses to PPRV and increased viral loads with lower basal expression levels of TLR 3/7. Upon stimulation of PBMC with synthetic TLR3 and TLR7 agonists or PPRV, the levels of proinflammatory cytokines were found to be significantly higher while immunosuppressive interleukin (IL 10 levels were lower in PPRV resistant Kanni and Salem Black breeds and water buffalo at transcriptional level, correlating with reduced viralloads in infected PBMC. Water buffalo produced higher levels of interferon (IFN α in comparison with goats at transcriptional and translational levels. Pre-treatment of Vero cells with human IFNα resulted in reduction of PPRV replication, confirming the role of IFNα in limiting PPRV replication. Treatment with IRS66, a TLR7 antagonist, resulted in the reduction of IFNα levels, with increased PPRV replication confirming the role of TLR7. Single nucleotide polymorphism analysis of TLR7 of these goat breeds did not show any marked nucleotide differences that might account for susceptibility vs resistance to PPRV.

    Full Text Available The swamp buffalo which is found in many Asian regions is mainly raised for meat and draft purposes. However, in West Sumatera, it is also milked and the milk is mostly consumed as “dadih“, a well known traditional product from this area. Dadih is actually a product made from fresh buffalo milk, which is kept in bamboo tube for about 2-3 days under room temperature, without any application or addition of bacteria starter although the end product of this fermentation contains various bacteria, mould and khamir. As the natural fermented milk product, dadih is white in colour and the curd texture like tofu, tastes like yoghurt, and it is generally served as a complementing meal in some traditional occasion as well as delicacy from West Sumatera. Dadih is highly nutritive product, protein and fat contents are higher than those of yoghurt, rich in amino acids and bacteria such as Lactobacillus sp. and low in cholesterol. The raw material for dadih is limited due to the low productivity of fresh buffalo milk which is generally collected for about 0.5 – 2.0 litres/head/day. The effort in sustaining “dadih product“ is directed to the improving the management of the buffalo condition particularly those in lactating period. Feeding improvement is recommended in order to provide an adequate milk for raising its calf and to be milked for making dadih and to support the optimal reproductive activity of the buffalo dam. In future, the assessment on “dadih“ should also include the packaging improvement which can improve and prolong the storage time for the benefit of marketing purposes.

    Full Text Available The buffalo is a domestic animal species of growing world-wide importance. Research to improve genetic improvement programs is important to maintain the productivity of buffalo. The objective this research was to evaluate the growth of Brazilian buffalo to two years of age with different growth curves. Growth curves consolidate the information contained in the weight-age data into three or four biologically meaningful parameters. The data included 31,452 weights at birth and 120, 205, 365, 550 and 730 days of buffalo (n = 5,178 raised on pasture without supplementation. Logistic, Gompertz, quadratic logarithmic, and linear hyperbolic curves (designated L, G, QL, and LH, respectively were fitted to the data by using proc NLIN of SAS (SAS Institute, Inc., Cary, NC, USA. The parameters estimates for L [WT= A * (((1 + exp (-k * AGE**-m] were A = 865.1 ± 5.42; k= 0.0028 ± 0.00002; M= 3.808 ± 0.007; R2 = 0.95. For G [WT= A * exp (-b * exp (-k * age] the parameters estimates were A= 967.6 ± 7.23; k = 0.00217 ± 0.000015; b = -2.8152 ± 0.00532. For QL [WT= A + b*age + k*(age*age + m*log (age] parameters estimates were A= 37.41 ± 0.48; k= 0.00019 ± 6.4E-6; b= 0.539 ± 0.006; m= 2.32 ± 0.23; R2=0.96. For LH [WT= A + b*AGE + k*(1/AGE] the parameters estimates were A= 23.15 ± 0.44; k=15.16 ± 0.66; b= 0.707 ± 0.001; R2= 0.96. Each of these curves fit these data equally well and could be used for characterizing growth to two years in beef buffalo.

    Full Text Available BACKGROUND: While prions play a central role in the pathogenesis of transmissible spongiform encephalopathies, the biology of these proteins and the pathophysiology of these diseases remain largely unknown. Since no case of bovine spongiform encephalopathy (BSE has ever been reported in buffalo despite their phylogenetic proximity to cattle, genetic differences may be driving the different susceptibilities of these two species to BSE. We thus hypothesized that differences in expression of the most recently identified member of the prion family or Shadoo (SPRN gene may relate to these species-specific differences. PRINCIPAL FINDINGS: We first analyzed and compared the polymorphisms of the SPRN gene (~4.4 kb, including the putative promoter, coding and 3' regions, and further verified the entire ORF and putative promoter. This yielded a total of 117 fixed differences, remarkably: 1 a 12-bp insertion/deletion polymorphism in the hydrophobic domain of the cattle but not buffalo gene, introducing a four amino acid expansion/contraction in a series of 5 tandem Ala/Gly-containing repeats; 2 two fixed missense mutations (102Ser→Gly and 119Thr→Ala, and three missense mutations (92Pro>Thr/Met, 122Thr>Ile and 139Arg>Trp in the coding region presenting different (P<0.05 genotypic and allelic frequency distributions between cattle and buffalo; and, 3 functional luciferase-reporter experiments for the predicted promoter region, consistent with a significantly higher activity in buffalo than cattle. Supporting these findings, immunoblotting revealed higher relative expression levels of Sho protein in cerebrum from buffalo than from cattle. In addition, for cattle, highest Sho expression was detected in obex, as compared to cerebrum or cerebellum. SIGNIFICANCE: Our findings support Sho as a non-PrP specific marker for prion infections, with obex as the best tissue source for the detection of Sho in TSE rapid tests. Moreover, these discoveries may prove

    We report an uncontrolled observational study of the treatment of udder diseases of buffalo, using a homeopathic complex medicine. Mastitis is an economically important disease of buffaloes. In India economic losses due to mastitis are estimated at 526 million US dollars annually. Conventional veterinary treatment relies on costly antibiotics; cure rate is only 60% in field conditions with a problem of milk residues. The present investigation was undertaken to evaluate the effectiveness of a homeopathic complex in the management of clinical udder health problems of riverine buffaloes. Cases of subclinical mastitis were excluded from the study. A total of 102 mastitic quarters (fibrosed--40, nonfibrosed--62) and five cases each of blood in milk and udder oedema in lactating buffaloes were treated with a homeopathic complex consisting of Phytolacca 200c, Calcarea fluorica 200c, Silicea 30c, Belladona 30c, Bryonia 30c, Arnica 30c, Conium 30c and Ipecacuanha 30c. The diagnosis of udder diseases and recovery criterion was based on physical examination of udder and milk and CMT/WST score. Bacteriological analysis and somatic cell count were not performed. Treatment was 80 and 96.72% effective in cases of fibrotic mastitis and nonfibrosed mastitis respectively. Recovery period was 21-42 days (fibrosed) and 4-15 days (nonfibrosed). Udder oedema and blood in milk responded favourably in 2-5 days. Cost of treatment was 0.07 US dollars per day. The homeopathic complex medicine may be effective and economical in the management of udder health problems of buffaloes. Definitive conclusions are premature due to the limited number of observations and lack of control group.

    Since commercial development of oil sands deposits began in the 1970s, mobile workers have been a presence in the Wood Buffalo region. Mobile workers are expected to remain in the Wood Buffalo region for some time, particularly given the investment plans of existing and new oil sands developers in the region. This report presented the findings of a study of mobile workers in the Wood Buffalo region. The purpose of the study was to obtain a better understanding of the general characteristics of mobile workers in the region; the impacts of the presence of mobile workers in terms of services, traffic, and money spent; and, how to attract workers to work or relocate in the region. The report outlined the background of the study, with particular reference to previous studies on mobile workers; study objectives; key questions; and study processes. The report also discussed methodological considerations and described the research process in detail. A demographic profile of mobile workers in the Wood Buffalo region was also provided and the time they spent working in the region was summarized. Last, the report provided an analysis of the interactions that mobile workers had with the urban service area of Fort McMurray rural communities, the backcountry in the rural areas of the region, and the town of Lac La Biche. It was concluded that mobile workers could be expected to remain a fixture of the industrial landscape in the Wood Buffalo region. Mobile workers in the heavy industrial construction industry have not considered settling in the region. 6 refs., 29 tabs., 5 figs., 3 appendices.

    Full Text Available 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.

  20. Ovarian and oviductal pathologies in the buffalo: Occurrence, diagnostic and therapeutic approaches

    Full Text Available Ovarian pathologies observed in the buffalo include developmental anomalies, inflammatory conditions and neoplasm's, the usual incidence of which has been observed to be low (0.1%–19.0% in abattoir studies. Ovarian functional disorders are the most frequently observed clinical entities in buffalo and include conditions such as sub estrus, (7.4%–55.8%, persistent corpus luteum (0.54% and ovarian cysts (0.5%–1.4%. The diagnostic approaches for ovarian hypofunction and ovarian pathologies include transrectal palpation and transrectal ultrasonography the efficiency of which continues to be suboptimal especially for unilateral small sized pathological conditions. Techniques such as laparoscopy have been utilized for visualization of buffalo ovaries however; their clinical use appears to be uncommon. The therapy of most ovarian pathologies except the functional disorders appears to be difficult. The prospects of surgical removal of ovaries in neoplastic ovarian pathologies are limited owing to the costs and loss of reproductive function under bilateral conditions. Oviductal pathologies in buffalo have been mentioned largely from abattoir studies and include salpingitis (0.2%–14.2%, hydrosalpinx (0.7%–14.2%, pyosalpinx (0.6%–11.9%, adhesions (1.5%–1.7%, congenital defects (0.2% and oviductal blockage (1.2%–37.8%. The diagnosis of most oviductal pathologies in buffalo appears to be difficult except under conditions of gross enlargement. Under situations of bilateral involvement the therapy of most oviductal pathologies currently seems impractical as the reattainment of fertility appears to be difficult.
