    Ultrastructural studies of sarcocysts obtained from Philippine water buffaloes revealed the presence of the commonly reported macroscopic species, Sarcocystis fusiformis, and the microscopic species Sarcocystis levinei (Dissanaike A, Kan S. Studies on Sarcocystis in Malaysia. I: Sarcocystis levinei n.sp. from the water buffalo Bubalus bubalis. Z Parasitenkd 1978;55:127-38), (Huong L, Dubey J, Uggla A. Redescription of Sarcocystis levinei Dissanaike and Kan, 1978 (Protozoa: Sarcocystidae) of the water buffalo (Bubalus bubalis). J Parasitol 1997;83:1148-52). The globular to oval microscopic cysts commonly observed in the muscles of the diaphragm and neck exhibit compartmentalized arrangement of zoites with septal partitions and measure 13-48 microns in diameter. The parasitophorous vacuolar membrane of sarcocyst bears minute and hair-like villar protrusions measuring 2.3-2.75 microns long emanating at certain distances from the primary cyst wall and lack microfilaments. Villar protrusions have expanded to dome-shaped base measuring 0.33-1.6 microns long by 0.22-1.0 micron wide, and intermediate and tapering distal segments bent approximately 90 degrees and run parallel to the cyst surface. The distal segments at some areas join to form conical tufts. The primary cyst wall bears numerous prominent undulations that are arranged in small clusters. The ground substance is 0.42-0.57 micron thick. This paper documents the first report of S. levinei in Philippine water buffaloes possessing the type 7 cyst wall. PMID:11227764

    Toxicosis caused by the ingestion of onion (Allium cepa) by 5 water buffalo (Bubalus bubalis) occurred in the district of Caçador, Santa Catarina, Brazil. The water buffalo died after ingestion of a large quantity of onion that had been left in the pasture. Clinical signs started 8 days postingestion and were characterized by pale mucous membranes, lethargy, and dark urine. At necropsy, pieces of onions were found in the rumen of 1 animal. The carcass smelled strongly of onion, and the kidneys and urine were dark brown. Microscopic renal lesions included tubular degeneration and necrosis with deposits of eosinophilic material in the cytoplasm of renal tubular epithelial cells and tubular lumina. These changes were consistent with hemoglobinuric nephrosis. Centrilobular coagulation necrosis was observed in the liver accompanied by hemorrhage and macrophages containing brown cytoplasmic pigment. A diagnosis of hemolytic anemia caused by onion toxicosis was based on the epidemiological data, clinical signs, macroscopic changes, and histological lesions. PMID:19407101

    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.

It is believed that the river buffalo was domesticated from Bubalus arnee, the wild buffalo of mainland Asia, a few thousand years ago, probably during the period of Indus Valley civilization. However, the domestication history of the river buffalo has been the subject of debate for many decades mainly due to the lack of clear archeological evidence and the divisive conclusions of the genetic studies. Therefore, in order to understand the domestication history and genetic relationship among the various river buffalo populations, we analyzed 492-bp region of mitochondrial DNA control region sequences of 414 river buffalo sampled from India, Pakistan, Egypt, and Iran along with the available 403 swamp buffalo sequences. The phylogenetic analyses of our study along with the archaeological evidence suggest that the river buffalo was domesticated in an atypical manner involving continuous introgression of wild animals to the domestic stocks in Indian subcontinent prior to mature phase of Indus Valley civilization (2600-1900 BC). Specifically, our data exclude Mesopotamian region as the place of domestication of the river buffalo. PMID:25900921

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

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

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

    Full Text Available Abstract Background 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 The Italian Mediterranean Buffalo (Bubalus bubalis has low fecundity and high incidence of abortion. Several studies have associated reproductive failure of water buffalo with viral infections but there is limited information on the role of chlamydial infections. To investigate the presence and the role of Chlamydiaceae in water buffalo a retrospective study was performed in a farm where, in the arch of 11 months, the pregnant heifers suffered an abortion rate of 36.8% in the 3rd and 5th month of pregnancy. Antibodies to Chlamydiaceae were detected in 57% of the aborted cows, while the rate of positivity was 0% in overtly healthy cows used as control. By a PCR assay 3 of 14 vaginal swabs from aborted animals tested positive for Chlamydophila agents and, additionally, 3 out of 7 aborted foetuses tested positive for Chlamydophila spp., with two being co-infections by Cp. abortus and Cp. pecorum and one being characterised as Cp. abortus. The presence of anti-Chlamydiaceae antibodies in 57% of the aborted animals and the detection of Chlamydophila agents in foetal organs and in vaginal swabs is consistent with the history of abortions (P<0.002 observed in the herd and may suggest a pathogenic role by Chlamydophila spp. in water buffalo.

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

    River buffalo are able to adapt to diverse climatic zones and are widespread globally. The resource use efficiency of buffalo is highly relevant in a resource-constrained world and the increasing requirement to produce more food. Buffalo clearly have an important role in meeting the growing demand for animal protein. In the Mediterranean and higher latitudes, buffalo show annual cycles of ovarian activity, embryonic development, and pregnancy rate. In buffalo, the CL starts to develop early in the cycle, and there is also an early increase in concentrations of progesterone (P4) in circulation. This appears to be necessary for optimal embryonic development. The failure to establish a pregnancy in buffalo can occur before Day 21 (early embryonic mortality), from Day 21 to 45 (late embryonic mortality), and from Day 46 to 90 (fetal mortality) after mating. Treatment with P4, hCG, and GnRH on Day 5 after mating increases P4 in circulation and reduces early embryonic mortality in circumstances where concentrations of P4 are relatively low. The same treatments applied on Day 20 to 25 after mating can lower the occurrence of late embryonic mortality and fetal mortality. PMID:27142486

    Estrus detection is a major problem in buffalo husbandry because of inconsistent expression of estrous signs at different seasons, and a high prevalence of the silent heat and postpartum anestrus in this species. Around 50% of the estrus events in buffaloes are currently undetected in the field conditions, resulting in a huge economic loss. Although the cervicovaginal fluid fern patterns confirm the estrus for a breeding decision, the fluid discharge is absent during the silent-heat condition. Therefore, the present study focused on the crystallization patterns of the saliva as an alternative method for estrus detection in buffaloes. Saliva is a body fluid available regularly, and its ferning ability before ovulation was established in women. In this study, eight female nonpregnant Murrah buffaloes (Bubalus bubalis) were considered during two experimental periods of 3 months each. One period was in summer with five animals, and another period was in rainy season with three animals. Estrus was determined by the estrus symptoms, ovarian ultrasonography, and salivary estradiol (E2) to progesterone (P4) ratio. A total of 450 saliva samples were collected from these animals on the daily basis. The salivary smear was prepared with 20 μL of the cell-free saliva on a clean glass slide, and its microscopic images were captured at a magnification of × 200. The images were used for fractal analysis as the salivary crystallization or fern patterns follow the fractal geometry. Saliva at estrus showed a typical symmetrical fern-like crystallization patterns with significantly (P buffaloes on the basis of distinct salivary crystallization patterns. The proportion of estrus detection by the salivary fern patterns was very significantly (P buffaloes. PMID:27181055

    Full Text Available Early postpartum follicular activity and sexual behavior was evaluated in the swamp buffalo (Bubalus bubalis in a tropical climate. Sixteen multiparous postpartum swamp buffaloes, 4-12 years of age, (432 - 676 kg were studied starting between 5-29 days after parturition. Ovarian follicular activity was examined daily in the morning with a real-time B-mode linear array ultrasound scanner (Aloka SSD-500, Tokyo, Japan equipped with a 7.5 MHz transrectal transducer. Estrous detection was performed daily using a mature bull, via personal observation as well as via video registration. In addition, vaginal discharge around estrus was evaluated. Uterine involution took 28.74+1.21 days (mean +SEM, range 22-41 d, n=16. Follicular activity prior to the first ovulation was characterized by a wave like pattern. Follicular growth rates and maximum diameter of the follicle in the second, third and fourth cycle post partum did not differ while that of the first ovulation follicle was significantly lower (p<0.05. Short ovarian cycles were observed in 93.3% of the buffaloes in the first to second ovulation interval (10.14+40 d, and in 50.0% of the buffaloes in the second to third ovulation interval (12.00+1.53 d, while one buffalo cow then had a long estrus cycle (27 d. The behavioral characteristics of estrus around the first postpartum ovulation were not as obvious as around the second, third and fourth postpartum ovulation. It can be concluded that for optimal reproductive efficiency the swamp buffalo should be mated between 1- 2 months postpartum at the second ovulation.

    Full Text Available Objective: In order to retain an undifferentiated pluripotent state, embryonic stem (ES cells have to be cultured on feeder cell layers. However, use of feeder layers limits stem cell research, since experimental data may result from a combined ES cell and feeder cell response to various stimuli. Materials and Methods: In this experimental study, a buffalo ES cell line was established from in vitro derived blastocysts and characterized by the Alkaline phosphatase (AP and immunoflourescence staining of various pluripotency markers. We examined the effect of various factors like fibroblast growth factor 2 (FGF-2, leukemia inhibitory factor (LIF and Y-27632 to support the growth and maintenance of bubaline ES cells on gelatin coated dishes, in order to establish feeder free culture systems. We also analyzed the effect of feeder-conditioned media on stem cell growth in gelatin based cultures both in the presence as well as in the absence of the growth factors. Results: The results showed that Y-27632, in the presence of FGF-2 and LIF, resulted in higher colony growth and increased expression of Nanog gene. Feeder-Conditioned Medium resulted in a significant increase in growth of buffalo ES cells on gelatin coated plates, however, feeder layer based cultures produced better results than gelatin based cultures. Feeder layers from buffalo fetal fibroblast cells can support buffalo ES cells for more than two years. Conclusion: We developed a feeder free culture system that can maintain buffalo ES cells in the short term, as well as feeder layer based culture that can support the long term maintenance of buffalo ES cells.

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

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

    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.

    OBJECTIVE To evaluate pharmacokinetics and bioavailability after administration of ceftiofur hydrochloride and ceftiofur sodium to water buffalo (Bubalus bubalis). ANIMALS 5 healthy adult water buffalo (3 males and 2 nonlactating females). PROCEDURES All animals received a dose (2.2 mg/kg) of 3 ceftiofur products (2 commercially available suspensions of ceftiofur hydrochloride [CEF1 and CEF2, IM] and ceftiofur sodium [CEF3, IV]). Blood samples were collected for up to 196 hours. Concentrations of ceftiofur in plasma were determined by use of high-performance liquid chromatography, and pharmacokinetic parameters were calculated on the basis of noncompartmental methods. RESULTS Most of the pharmacokinetic parameters, except for bioavailability and the area under the concentration-time curve extrapolated to infinity, were significantly different between the 2 products administered IM. Mean ± SD bioavailability of CEF1 and CEF2 was 89.57 ± 32.84% and 86.28 ± 11.49%, respectively, which indicated good absorption of both products. In addition, there was a longer drug residence time for CEF1 than for CEF2. Data analysis for CEF1 revealed a flip-flop phenomenon. CONCLUSIONS AND CLINICAL RELEVANCE In this study, there was good absorption of CEF1, and CEF1 had a longer drug residence time in vivo than did CEF2. On the basis of pharmacokinetic parameters and the in vitro antimicrobial susceptibility, a dosage regimen of 2.2 mg/kg administered at 48- and 36-hour intervals for CEF1 and CEF2, respectively, could be an appropriate choice for the treatment of buffalo with infectious diseases.

    Cloning, high-level expression, and characterization of the somatotropin (ST) gene of an indigenous Nili-Ravi breed of water buffalo Bubalus bubalis (BbST) are described. Coding, non-coding, and promoter regions of BbST were amplified and sequenced. Sequence analysis revealed several silent and two interesting point mutations on comparison with STs of other vertebrate species. One interesting variation in the BbST sequence was the replacement of a conserved glutamine residue by arginine. A plasmid was also constructed for the production of BbST in Escherichia coli BL21 (RIPL) CodonPlus, under the control of IPTG-inducible T7-lac promoter. High-level expression could be obtained by synthesizing a codon-optimized ST gene and expressing it in the form of inclusion bodies. The inclusion bodies represented over 20% of the E. coli cellular proteins. The biologically active conformation of purified BbST was confirmed by its efficient growth promoting activity in Nb2 cell proliferation assay. The expression system and purification strategy employed promise to be a useful approach to produce BbST for further use in structure-function studies and livestock industry. PMID:17367293

    One of the major difficulties in studying the mechanisms of host defense in economically important species indigenous to Asia and the Middle East is the lack of monoclonal antibody (mAb) reagents that define the immune systems of species other than cattle, goats, sheep, and pigs. One strategy that could obviate this problem at minimal cost is to identify existing mAbs that recognize conserved epitopes on orthologous major histocompatibility complex (MHC) and leukocyte differentiation molecules. To explore the potential of this approach, we screened a large set of mAbs that recognize bovine MHC class I and II molecules and leukocyte differentiation molecules to identify mAbs that react with orthologous molecules in water buffalo. One hundred thirty eight were found that recognize conserved determinants on orthologous molecules. In addition to identifying a useful set of reagents, the study has provided insight into the composition of the immune system of the water buffalo (Bubalus bubalis). PMID:14614279

    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

    Full Text Available AbPasrtartuabcetrculosis is a chronic infection of domestic and wild ruminants, caused by Mycobacterium avium subsp. paratuberculosis. The persistence of paratuberculosis infection for months up to years without exhibiting any clinical signs makes the diagnosis and control program a difficult proposition. Limited informations on prevalence of paratuberculosis in water buffaloes (Bubalus bubalis are available. We carried out a study on 1350 buffaloes belonging to 56 herds in the Caserta province, of Campania region, Italy. The prevalence of infected buffalo dairy herds was estimated by a commercial ELISA kit of individual blood samples of animals over 24 months of age. On the basis of performance (sensitivity 43%, specificity 99.3% of ELISA test on serum, the resulting true prevalence at animal level and at herd level was 4% (95% CI 3% to 5% and 74,1% (95% CI 71.8% to 76%. Considering the paucity of epidemiological reports in the region our results could be a useful contribution towards the prevention of buffalo paratuberculosis in the area.

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

    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

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

    In this study, genetic diversity analysis of MHC class II-DQA locus helped in identification of 25 new Bubu-DQA nucleotide sequences in swamp buffaloes (Bubalus bubalis carabanesis, Bubu). Phylogenetic analysis revealed the distribution of the buffalo DQA sequences in two major clusters of DQA1 and DQA2 genes, sharing common lineages with corresponding cattle alleles, possibly due to trans-species evolution. However, a highly divergent sequence, Bubu-DQA*2501, homologous to cattle (BoLA) DQA3 allele, was identified, indicating the existence of an additional locus; putative DQA3 in buffalo. PCR-RFLP analysis revealed extensive duplication of DQA locus in swamp buffaloes, sharing DQA1, DQA2, and DQA3 alleles in different combinations in duplicated haplotypes. Higher dN than dS values and Wu-Kabat variability at peptide-binding regions in Bubu-DQA indicated high polymorphism with balancing selection. Levels of genetic diversity within DQA sequences and duplication in a small population of swamp buffalo indicate the genetic richness of the species, important for fitness. PMID:27177904

    Water buffaloes (Bubalus bubalis) act as carrier to Theileria annulata and show less clinical sign of tropical theileriosis as compared to indigenous and exotic cattle. Differential expression of immune-related genes such as major histocompatibility complex, class II, DQ alpha 1 (MHC-DQα), signal-regulatory protein alpha (SIRPA), prion protein (PRNP), Toll-like receptor 10 (TLR10), c-musculoaponeurotic fibrosarcoma oncogene homolog (cMAF) and V-maf avian musculoaponeurotic fibrosarcoma oncogene homolog B (MAFB) genes influence host resistance to this disease in exotic, crossbred and indigenous cattle. In the present study we examined the differential mRNA expression of the abovesaid immune-related genes in response to T. annulata infection in buffaloes. Peripheral blood mononuclear cells (PBMCs) harvested from blood samples of buffaloes were challenged with ground-up tick supernatant carrying T. annulata sporozoites in vitro. After 48h of in vitro challenge qPCR was employed to measure the relative mRNA expression of MHC-DQα, SIRPA, PRNP, TLR10, cMAF and MAFB genes in infected and control PBMCs. In the current study, the selected genes showed no change in mRNA expression after T.annulata infection which indicates that they have little role in providing host resistance to theileriosis in buffaloes.

    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 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 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.

    Hot season is a major constraint to production and reproduction in buffaloes. The present work aimed to investigate the effect of season on ovarian function, developmental competence, and the relative abundance of gene expression in buffalo oocytes. Three experiments were conducted. In experiment 1, pairs of buffalo ovaries were collected during cold season (CS, autumn and winter) and hot season (HS, spring and summer), and the number of antral follicles was recorded. Cumulus oocyte complexes (COCs) were aspirated and evaluated according to their morphology into four Grades. In experiment 2, Grade A and B COCs collected during CS and HS were in vitro matured (IVM) for 24 hours under standard conditions at 38.5 °C in a humidified air of 5% CO2. After IVM, cumulus cells were removed and oocytes were fixed, stained with 1% aceto-orcein, and evaluated for nuclear configuration. In vitro matured buffalo oocytes harvested during CS or HS were in vitro fertilized (IVF) using frozen-thawed buffalo semen and cultured in vitro to the blastocyst stage. In experiment 3, buffalo COCs and in vitro matured oocytes were collected during CS and HS, and then snap frozen in liquid nitrogen for gene expression analysis. Total RNA was extracted from COCs and in vitro matured oocytes, and complementary DNA was synthesized; quantitative Reverse Transcription-Polymerase Chain Reaction was performed for eight candidate genes including GAPDH, ACTB, B2M, GDF9, BMP15, HSP70, and SOD2. The results indicated that HS significantly (P ovary. The number of Grade A, B, and C COCs was lower (P quality. In vitro maturation of buffalo oocytes during HS impairs their nuclear and cytoplasmic maturation, fertilization, and subsequent embryo development to the morula and blastocyst stages. This could be in part because of the altered gene expression found in COCs and in vitro matured oocytes. PMID:25156970

    High ambient temperature during summer in tropical and subtropical countries predisposes water buffaloes (Bubalus bubalis) to develop oxidative stress having antigonadotropic and antisteroidogenic actions. Melatonin is a regulator of seasonal reproduction in photoperiodic species and highly effective antioxidant and free radical scavenger. Therefore, a study was designed to evaluate the effect of sustained-release melatonin on biomarkers of oxidative stress i.e., the serum malondialdehyde (MDA) and nitric oxide (NO), and the total antioxidant capacity (TAC). For the study, postpartum buffaloes diagnosed as summer anestrus (absence of overt signs of estrus, concurrent rectal examination, and RIA for serum progesterone) were grouped as treated (single subcutaneous injection of melatonin at 18 mg/50 kg body weight dissolved in sterilized corn oil as vehicle, n = 20) and untreated (subcutaneous sterilized corn oil, n = 8). Blood sampling for estimation of serum TAC and MDA (mmol/L) and NO (μmol/L) was carried out at 4 days of interval from 8 days before treatment till 28 days after treatment or for the ensuing entire cycle length. Results showed serum TAC concentration was higher in the treatment group with a significant (P stress resulting in the induction of cyclicity in summer-stressed anestrous buffaloes. PMID:25805692

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

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

Fifty healthy Iranian water buffalos (33 females, 17 males, aged 1-15 years, of four different ecotypes-Azeri, Mazandarani, Khuzestani and Guilani were selected and divided into 4 age groups. Swabs were taken from the inferior conjunctival sac of both eyes (n = 100 and cultured on blood and MacConkey agar in aerobic condition. Forty seven buffalos out of 50 (94% were positive for bacteria; 44/50 (88% had positive culture from both eyes. The most frequent isolates were Staphylococcus sp., Escherichia coli and Bacillus cereus. Statistical analysis did not show significant difference in frequency of isolates between sexes, ecotypes and age groups (p>0.05. A correlation was found between the buffalo age and number of species isolated per eye (p<0.01. In this study Dermatophilus congolensis and Edwardsiella tarda were reported for the first time in the conjunctiva of animals. Gram-positive aerobes were most commonly cultured from the conjunctival sac of healthy water buffalos.

    Fifty non-pregnant Surti buffalo heifers aged between 17 and 42 months ( n=24, 24 months) were randomly assigned to groups subject to either natural daylight +4h supplemental light ( n=25) or natural day light ( n=25), to study changes in growth, serum prolactin (Prl), progesterone (P4) and luteinizing hormone (LH) to supplemental lighting. Ambient temperatures (T) and relative humidity (RH) generally were >27° C and buffaloes under similar planes of nutrition. While light supplementation did not have a positive effect on body wieght during the 10 week study, body weight and endocrine changes due to supplemental light may be important factors for initiation of reproductive cyclicity.

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

    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 Caseins comprise make up about 80% of the total protein content of milk and present polymorphism with changes in the amino acid sequence. Within this abundance of proteins, kappa-casein is noteworthy, since it has been associated with differences in milk yield, composition and processing. The objective of this study was to observe the existence of polymorphism in the kappa-casein gene in female buffaloes. For this purpose, blood samples from 115 female buffaloes, collected with vacutainer by needle punctionure of the jugular vein, were used. for genomic DNA extraction was done from blood samples. The PCR-RFLP and SSCP techniques demonstrated that the studied animals were monomorphic for the kappa-casein gene. Only allele B was observed in these animals, which was present in homozygosis. Therefore, it was not possible to quantify the gene action on milk yield and its constituents. The monomorphism observed in the population studied would allow the development of a method to identify mixtures of cow and buffalo milk in mozzarella cheese production, especially because, in cattle, the kappa-casein gene is polymorphic.

    The definitive hosts of Sarcocystis sinensis in water buffaloes have hitherto been unknown, but the close similarity of this species to the cat-transmitted Sarcocystis bovifelis in cattle suggested they were felids. In a previous study, two domestic cats were fed macroscopic sarcocysts of Sarcocystis fusiformis contained within or dissected from the esophageal muscles of water buffaloes, while no microscopic sarcocysts of S. sinensis were noticed. Both cats started shedding small numbers of sporocysts 8-10 days post infection (dpi) and were euthanized 15 dpi. Using a PCR-based molecular assay targeting the mitochondrial cox1 gene of S. fusiformis, both cats were shown to act as definitive hosts for this species. In the present study, DNA samples derived from oocysts/sporocysts in the intestinal mucosa of both cats were further examined by PCR for the presence of S. sinensis using 2 newly designed primers selectively targeting the cox1 gene of this species. All 6 DNA samples examined from each cat tested positive for S. sinensis. A 1,038-bp-long portion of cox1 was amplified and sequenced as 2 overlapping fragments from 5 of these DNA samples. The 5 sequences shared 99.3-100% identity with 7 previous cox1 sequences of S. sinensis obtained from sarcocysts in water buffaloes. Additionally, amplification of the ITS1 region with primers targeting various Sarcocystis spp., yielded amplicons of 2 different lengths, corresponding to those obtained from sarcocyst isolates of S. sinensis and S. fusiformis, respectively. This is the first study to show that cats act as definitive hosts for S. sinensis. PMID:27075117

    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.

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

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

    International Nuclear Information System (INIS)

    In present study the clinico-pathological findings were recorded in naturally infected cattle and buffaloes due to pasteurella multocida during an outbreak at different livestock herds. There was no significant difference in mortality among various groups of buffaloes (p>0.78) and cattle (p>0.49). The infected animals showed clinical signs of moderate to acute anorexia, salivation, fever, depression, dysponea, submandibular edema, mucopurulent nasal discharge and respiratory grunts. Few of infected animals died due to septicemia. the necropsy of dead animals was performed and visceral organs lungs, kidneys, heart and lymph nodes were observed for gross and histopathological lesions. The tissue samples from these organs were fixed in formalin for pathological changes. Necropsy of dead animals revealed severe pneumonia, consolidation of lungs and intense pleural adhesions. serosanguinous fluid was accumulated in pericardium and peritoneal cavities. Histopathologically affected lungs exhibited severe congestion, mononuclear cell infiltration, thick interlobular septae punctuated with macrophages, plasma cells and peri-vascular cuffing. Liver, kidneys and lymph nodes had degenerative changes in histological sections. The specificity of p. multocida was determined by colony characteristics on macconkey's agar and morphological features with gram's iodine. The pcr product size approximately 511bp from lung tissues confirmed a total of 82% (19/23) bacterial isolates from dead animals. (author)

    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.

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

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

    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.

    2011-03-01

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

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

    Full Text Available Aim: The present study was aimed 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.

Results: A weak activity of phosphatases and oxidoreductases was observed in the acinar cells and ductular epithelium at 11-19 cm CVRL (78-114 days. From 28 to 37 cm CVRL (136-157 days, a weak to moderate diffused granular alkaline phosphatase (AKPase activity was observed in the seromucous acini whereas oxidoreductases showed moderate activity. The enzyme activity showed progressively increased with the advancement of the gestation period. The AKPase activity was more in the lumen of acini and along the intercellular canaliculi at 42-100 cm of CVRL (168 days - full term. Large ducts exhibited strong activity for oxidoreductases indicating increased metabolic activity of the cells. Conclusion: The fetuses of Group I showed a uniform weak activity in the acinar cells and ductular epithelium of the gland. In Group II, the enzymes showed a weak to moderate activity which progressively increased with the advancement of gestation period. The enzymes related to Group III showed a strong positive activity for enzymes which reflected higher secretory activity of the gland.

    Full Text Available 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........

    The aims of the current study were to describe presence and clinical role over time of Streptococcus pluranimalium isolated in milk samples of Mediterranean buffalo (MB). Two hundred composite milk samples originating from 40 primiparous MB were collected at 10, 30, 60, 90, and 150d in milk (DIM) and from 20 pluriparous MB at 77 to 120 DIM. Milk samples were used for analysis of somatic cell counts, bacteriological cultures, and identification (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry). Nine of 200 (4.5%) samples of primiparous MB and 3 of 20 (15%) samples of pluriparous MB were positive for Strep. pluranimalium. The prevalence of the bacterium in primipari was 0% (0/40) at 10, 30, and 150 DIM, whereas it was 5 (2/40) and 17.5% (7/40) at 60 and 90 DIM, respectively. Eight primipari were positive only once, whereas 1 was positive at 2 different samplings. Mono-infection was not detected in any of the age categories or udder health status. Infections were transient in primipari. Clinical mastitis was observed in primipari once at 90 DIM, subclinical mastitis detected twice in the same animals at 60 and 90 DIM, and intramammary infections were diagnosed 1 and 5 times at 60 and 90 DIM in primipari, respectively, whereas 3 infections were diagnosed in pluripari. The clinical reflections demonstrate for the first time the presence of Strep. pluranimalium in MB and its association with different udder health status. Nevertheless, it cannot be excluded that the bacterium may simply follow a pattern of commensal or opportunistic behavior, taking advantage of a preexisting bacterial udder infection. PMID:26805969

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

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

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

    Full Text Available Ten adult female water buffalo were used in the present study (5 x [2n = 50] and 5 x [2n= 49] hybrids. Ovarian activity was monitored daily by transrectal ultrasonography between two consecutive ovulations. Observed follicular wave numbers were: 1 (n=1, 2 (n=4, and 3 (n=5. The interovulatory interval ranged 17 to 23 days. Differences in mean follicular diameter between follicles of the normal karyotype (2n=50 and buffalo hybrids (2n=49 were found on the second subordinate group of follicles (P0.05, whereas inhibin profiles were significantly higher in the hybrid group (P<0.05. Understanding the biological meaning of the difference in inhibin concentrations in B. bubalis female reproductive performance will require further investigation.

    Data from three published studies of genetic variation at 18 microsatellite loci in water buffalo populations in China (18 swamp type, two river type), Nepal (one wild, one domestic river, one hybrid) and south-east Asia (eight swamp, three river) were combined so as to gain a broader understanding of genetic relationships among the populations and their demographic history. Mean numbers of alleles and expected heterozygosities were significantly different among populations. Estimates of θ (a measure of population differentiation) were significant among the swamp populations for all loci and among the river populations for most loci. Differentiation among the Chinese swamp populations (which was due primarily to just one population) was much less than among the south-east Asian. The Nepal wild animals, phenotypically swamp type but genetically like river type, are significantly different from all the domestic river populations and presumably represent the ancestral Bubalus arnee (possibly with some river-type introgression). Relationships among the swamp populations (D(A) genetic distances, principal component analysis and structure analyses) show the south-east Asian populations separated into two groups by the Chinese populations. Given these relationships and the patterns of genetic variability, we postulate that the swamp buffalo was domesticated in the region of the far south of China, northern Thailand and Indochina. Following domestication, it spread south through peninsular Malaysia to Sumatra, Java and Sulawesi, and north through China, and then to Taiwan, the Philippines and Borneo. PMID:21749419

    Full Text Available Background: This research studies the effects of activation and inhibition of Wnt3A signaling pathway in buffalo (Bubalus bubalis embryonic stem (ES cell-like cells. Materials and Methods: To carry on this experimental study, the effects of activation and inhibition of Wnt3A signaling in buffalo ES cell-like cells were examined using Bio (0.5 mM combined with WNT3A (200 ng/ml, as an activator, and Dickkopf-1 (Dkk1, 250 ng/ml, as an inhibitor, of the pathway. ES cells were cultured up to three weeks in ES cell medium without fibroblast growth factor-2 (FGF-2 and leukemia inhibitory factor (LIF, but in the presence of Bio, WNT3A, Bio+WNT3A and Dkk1. The effects of these supplements were measured on the mean area of ES cell colonies and on the expression levels of a number of important genes related to pluripotency (Oct4, Nanog, Sox2 and c-Myc and the Wnt pathway (β-catenin. ES cell colonies cultured in ES cell medium that contained optimized quantities of LIF and FGF-2 were used as the control. Data were collected for week-1 and week-3 treated cultures. In addition, WNT3A-transfected ES cells were compared with the respective mock-transfected colonies, either alone or in combination with Dkk1 for expression of β-catenin and the pluripotency-related genes. Data were analyzed by ANOVA, and statistical significance was accepted at P<0.05. Results: Among various examined concentrations of Bio (0.5-5 mM, the optimum effect was observed at the 0.5 mM dose as indicated by colony area and expressions of pluripotency- related genes at both weeks-1 and -3 culture periods. At this concentration,the expressions of Nanog, Oct3/4, Sox2, c-Myc and β-catenin genes were nonsignificantly higher compared to the controls. Expressions of these genes were highest in the Bio+WNT3A treated group, followed by the WNT3A and Bio-supplemented groups, and lowest in the Dkk1-treated group. The WNT-transfected colonies showed higher expressions compared to both mock and Dkk1

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

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

    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. PMID:26354679

    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.

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

    The post-thaw fertility of frozen-thawed mammalian spermatozoa is substantially low as compared with that of fresh sperm. Furthermore, the post-thaw fertility of the cryopreserved buffalo sperm has been reported to be poor as compared with that of cattle sperm. Recently, heat shock protein 70 (HSP70) has been found to play a critical role in mammalian fertilization and early embryonic development in boar and cattle. However, the presence of such fertility-related HSP70 in buffalo sperm and its status after cryopreservation has not been reported so far. Thus, a study was conducted to determine the effect of cryopreservation on the level and distribution pattern of HSP70 molecule in buffalo sperm after cryopreservation. Buffalo semen samples, after dilution in semen extender, were aliquoted in straws and divided into two groups. One group was not cryopreserved, and the other group was cryopreserved for 60 days. Sperm proteins were extracted from both non-cryopreserved (NC) and cryopreserved (C) sperm and subjected to Western blot analysis for detection of HSP70 using a monoclonal anti-HSP70 antibody. The distribution pattern of these proteins in buffalo sperm was also monitored before and after cryopreservation using indirect immunofluorescence technique. A prominent 70-kDa protein band of HSP70 protein was detected in protein extracts of both NC and C buffalo sperm. Densitometry analysis revealed that the intensity of 70-kDa HSP70 protein band of cryopreserved sperm decreased significantly (P sperm. However, the level of HSP70 in cryopreserved extended seminal plasma (ESP) did not change as compared with that of NC samples indicating a possible degradation of HSP70 in the spermatozoa itself rather than leakage of the protein into the ESP. Furthermore, Western blot also confirmed that several HSP70 immunoreactive protein bands detected in the ESP were contributed by the egg yolk that was added to the extender. Immunocytochemistry revealed that HSP70 proteins were

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

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

    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.

    Several 1-acylglycerol-3-phosphate-O-acyltransferases (AGPATs) can acylate lysophosphatidic acid to produce phosphatidic acid. Of the eight AGPAT isoforms, AGPAT6 is a crucial enzyme for glycerolipids and triacylglycerol biosynthesis in some mammalian tissues. We amplified and identified the complete coding sequence (CDS) of the water buffalo AGPAT6 gene by using the reverse transcription-polymerase chain reaction, based on the conversed sequence information of the cattle or expressed sequence tags of other Bovidae species. This novel gene was deposited in the NCBI database (accession No. JX518941). Sequence analysis revealed that the CDS of this AGPAT6 encodes a 456-amino acid enzyme (molecular mass = 52 kDa; pI = 9.34). Water buffalo AGPAT6 contains three hydrophobic transmembrane regions and a signal 37-amino acid peptide, localized in the cytoplasm. The deduced amino acid sequences share 99, 98, 98, 97, 98, 98, 97 and 95% identity with their homologous sequences from cattle, horse, human, mouse, orangutan, pig, rat, and chicken, respectively. The phylogenetic tree analysis based on the AGPAT6 CDS showed that water buffalo has a closer genetic relationship with cattle than with other species. Tissue expression profile analysis shows that this gene is highly expressed in the mammary gland, moderately expressed in the heart, muscle, liver, and brain; weakly expressed in the pituitary gland, spleen, and lung; and almost silently expressed in the small intestine, skin, kidney, and adipose tissues. Four predicted microRNA target sites are found in the water buffalo AGPAT6 CDS. These results will establish a foundation for further insights into this novel water buffalo gene. PMID:24114207

    Oviductin is a high molecular weight oviduct-specific glycoprotein secreted by the non-ciliated epithelial cells of oviduct during estrous cycle and early pregnancy. It plays an important role during fertilization and early embryonic development. The oviductin gene from oviductal tissues of buffalo was successfully cloned and sequenced. The sequence analysis revealed that buffalo and cattle oviductin share very high homology between their cDNA sequences. The predicted amino acid sequences of the buffalo oviductin exhibited the highest percent of identity of 97 % with bovine followed by 94 % with goat, 93 % with sheep, 78 % with porcine, 72 % with human, 67 % with hamster and rabbit and 65 % with mouse. Oviductin was also observed to share high similarity with the mammalian chitinase, however oviductins do not show chitinase activity due to Glu→Ile mutation in the active site responsible for chitinase activity. The phylogenetic tree based on amino acid sequences of oviductin indicated that buffalo oviductin was closely related to its cattle counterpart, and this clustering is in accordance with the classic taxonomic relationship. Tissue specific expression of the transcripts for buffalo oviductin revealed a high level expression in oviduct and ovary followed by testis, mammary gland, kidney, while in mammary epithelial cells and liver its expression was very low. The full length matured oviductin and its domains constituting chitinase-like domain and mucin-like domain were cloned into pET and pGEX series of expression vectors and over expressed in E. coli. The soluble recombinant oviductin was successfully purified to homogeneity. Full length recombinant oviductin was expressed partially in soluble form, where as the chitinase-like and mucin-like domains of oviductin were expressed in insoluble form and aggregating to form inclusion bodies at both 37 and 16 °C induction temperatures.

    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.

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

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.

    The present study was undertaken to explore the potential of the Murrah breed of buffaloes as donors of oocytes and to find out the recovery rate and oocyte quality in cyclic Murrah buffaloes subjected to oocyte recovery once a week. Murrah buffaloes (n = 5) were synchronized for estrus by a single prostaglandin injection schedule. The animals were subjected to transvaginal oocyte retrieval (TVOR) once weekly for 6 weeks, starting from Day 7 of the oestrous cycle (Day 0 = day of oestrus). TVOR was performed using an ultrasound machine with a 5 MHz transvaginal transducer, single lumen 19-gauge, 60 cm long needle and a constant vacuum pressure of 50 mmHg. The number and size of follicles in each ovary was determined before puncture. The follicles were characterized on the basis of their diameter as small (3-5 mm), medium (6-9 mm) and large (> or = 10 mm). The oocytes recovered were classified as grade A, cumulus-oocytes complexes (COCs) with > or = 5 layers of cumulus cells; grade B, those with two to four layers; grade C, partially denuded oocytes; and grade D, completely denuded oocytes. The mean (+/- S.E.M) number of small, medium and large follicles, and the number of total follicles observed per animal per session, which was 2.2 +/- 0.3, 0.6 +/- 0.2, 0.9 +/- 0.1 and 3.7 +/- 0.3, respectively, did not differ between animals or between puncture sessions. Small follicles constituted a major proportion (59%) of the total observed follicles. A mean (+/- S.E.M) number of 3.0 +/- 0.3 follicles were punctured and 2.0 +/- 0.3 oocytes recovered per animal per session, with a recovery rate of 68%. Out of the total 61 oocytes recovered, 36 (59%) were of grades A + B whereas 25 (41%) were of grades C + D. In conclusion, this study describes the potential of cyclic Murrah buffaloes as donors of oocytes collected by repeated TVOR once a week, without any adverse effects on follicular growth and oocyte recovery. It also describes an efficient system for carrying out TVOR in

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

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

    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 plasma level of growth hormone, insulin-like growth factor-1 (IGF-1), triiodothyronine (T3) and lower concentration of thyroxin hormone were detected. No significant differences in levels of insulin, hydroxyproline, plasma and urine creatinine, total protein and albumin between high and low RFI groups were found. Blood metabolites showed significant (p < 0.05) differences at initial and final stages of study in both groups. At final stage of study, RFI showed negative correlations with growth hormone, IGF-1, T3, urine creatinine and albumin. Low RFI buffalo calves are more efficient in feed utilisation and the differences in blood metabolites are probably due to differences in feed intake and body metabolism. PMID:27666680

    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.

    The effects of equilibration times (E1, 2 h; E2, 4 h; E3, 6 h), freezing rates (FR1, manual, 5 cm above liquid nitrogen (LN2 ) for 10 min, plunging in LN2 ; FR2, programmable ultra-fast, holding at +4 °C for 2 min, from 4 to -10 °C at -10 °C/min, from -10 to -20 °C at -15 °C/min, from -20 to -120 °C at -60 °C/min, holding at -120 °C for 30 sec, plunging in LN2 ), and thawing rates (T1, 37 °C for 30 sec; T2, 50 °C for 15 sec; T3, 70 °C for 7 sec) were evaluated on quality of buffalo bull spermatozoa. Progressive motility (%), rapid velocity (%), average path velocity (VAP, μm/s), straight line velocity (VSL, μm/s), and mitochondrial transmembrane potential (%) were higher (p plasma membrane integrity (%), viability and acrosome integrity (%) of spermatozoa were higher (p < 0.05) with E2 and FR2 compared to other groups. Sperm DNA integrity (%) was higher (p < 0.05) with FR2 and T1 compared to other groups. We concluded that inclusion of 4 h-equilibration time, programmable ultra-fast freezing rate, and rapid thawing at 70 °C for 7 sec in cryopreservation protocol improves the post-thaw quality of buffalo bull spermatozoa.

    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%.

    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.

  1. Serum levels of triiodothyronine (T3) and thyroxine (T4) in buffalo (Bubalus bubalis Lin.) raised in Amazon region

    International Nuclear Information System (INIS)

    Through the use of radioimmunoassay (RIA) it was determined blood serum concentration of triiodothyronine (T3) and thyroxine (T4) (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 T3 and T4 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

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

    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 efficiency of two cell types, namely adult fibroblasts, and amniotic fluid stem (AFS) cells as nuclear donor cells for somatic cell nuclear transfer by hand-made cloning in buffalo (Bubalus bubalis) was compared. The in vitro expanded buffalo adult fibroblast cells showed a typical "S" shape growth curve with a doubling time of 40.8 h and stained positive for vimentin. The in vitro cultured undifferentiated AFS cells showed a doubling time of 33.2 h and stained positive for alkaline phosphatase, these cells were also found positive for undifferentiated embryonic stem cell markers like OCT-4, NANOG and SOX-2, which accentuate their pluripotent property. Further, when AFS cells were exposed to corresponding induction conditions, these cells differentiated into osteogenic, adipogenic and chondrogenic lineages which was confirmed through alizaran, oil red O and alcian blue staining, respectively. Cultured adult fibroblasts and AFS cells of passages 10-15 and 8-12, respectively, were used as nuclear donors. A total of 94 embryos were reconstructed using adult fibroblast as donor cells with cleavage and blastocyst production rate of 62.8 ± 1.8 and 19.1 ± 1.5, respectively. An overall cleavage and blastocyst formation rate of 71.1 ± 1.2 and 29.9 ± 2.2 was obtained when 97 embryos were reconstructed using AFS cells as donor cells. There were no significant differences (P > 0.05) in reconstructed efficiency between the cloned embryos derived from two donor cells, whereas the results showed that there were significant differences (P < 0.05) in cleavage and blastocyst rates between the cloned embryos derived from two donor cell groups. Average total cell numbers for blastocyst generated using AFS cells (172.4 ± 5.8) was significantly (P < 0.05) higher than from adult fibroblasts (148.2 ± 6.1). This study suggests that the in vitro developmental potential of the cloned embryos derived from AFS cells were higher than that of the cloned embryos

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

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

    BACKGROUND: Pregnancy-associated glycoproteins (PAGs) were first described as placental antigens present in the blood serum of the mother soon after implantation. Here, we describe the purification of several pregnancy-associated glycoproteins from water buffalo placenta (wbPAGs). A specific radioimmunoassay (RIA) was developed for early pregnancy diagnosis in buffalo species. RESULTS: Amino-terminal microsequencing of immunoreactive placental proteins allowed the identification of eleven wbP...

    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  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.

    The aim of the present study was construction of mammary gland specific expression vector for high level of human insulin (hINS) expression in transgenic buffalo for therapeutic use. We have constructed mammary gland specific vector containing human insulin gene and there expression efficiency was checked into in vitro cultured buffalo mammary epithelial cells (BuMECs). Human pro-insulin coding region was isolated from human genomic DNA by intron skipping PCR primer and furin cleavage site was inserted between B-C and C-A chain of human insulin by overlap extension PCR. A mammary gland-specific buffalo beta-lactoglobulin promoter was isolated from buffalo DNA and used for human insulin expression in BuMEC cells. The construct was transfected into BuMECs by lipofection method and positive transgene cell clones were obtained by G418 selection after 3 weeks. Expression of hINS in transfected cells were confirmed by RT-PCR, Immunocytochemistry, Western Blotting and ELISA. The pAcISUBC insulin-expressing clones secreted insulin at varying levels between 0.18 - 1.43 ng/ml/24 h/2.0 × 10(6) cells. PMID:24969480

    Male (n=66) water buffalo (Buffalo) and Brahman-influenced cattle (Brahman) were born, raised, weaned, fattened on grazing savannah and harvested at two different ages (19 and 24months) to compare lipid composition of the longissimus thoracis muscle. Half of the animals were castrated at seven months of age (MOA) to examine the castration effects. At 24 MOA Brahman steers showed the highest content of total lipids (P<0.05). No significant variation was detected in cholesterol content for either the main or interaction effects in the age groups. Some individual fatty acids varied with the species (P<0.05), however, interspecific similarities were found in fatty acid ratios. For health-related indices, only atherogenic index (AI) showed lower values in favor of Buffalo meat (P<0.05) at both harvesting ages. Although, meat derived from both bovid groups was leaner and showed lower cholesterol level, AI indicates that Buffalo meat might be beneficial from a human health standpoint. PMID:25879797

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

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

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

    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 (pbenchmark. 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. PMID:25049573

    The present investigation was done to study the effect of caspase-9 inhibitor Z-LEHD-FMK, on in vitro produced buffalo embryos. Z-LEHD-FMK is a cell-permeable, competitive and irreversible inhibitor of enzyme caspase-9, which helps in cell survival. Buffalo ovaries were collected from slaughterhouse and the oocytes were subjected to in vitro maturation (IVM), in vitro fertilization (IVF) and in vitro culture (IVC). The culture medium was supplemented with Z-LEHD-FMK at different concentrations i.e. 0 μM (control), 10 μM, 20 μM, 30 μM and 50 μM during IVM and IVC respectively. After day-2 post-insemination, the cleavage rate was significantly higher (74.20 ± 5.87% at Pafore mentioned results we conclude that, Z-LEHD-FMK at 20 μM increased the cleavage and blastocyst rate of buffalo pre-implantation embryos also affecting the rate of apoptosis and cellular stress at various concentrations.

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

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

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

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

    The serological profiles of 21 female buffaloes vaccinated between 3 and 8 months of age using Brucella abortus strain 19 (S19) were evaluated by rose bengal (RBT), 2-mercaptoethanol (2ME) and complement fixation (CFT) tests. The serum strains were collected in day zero, 15, 30, 45, 60th days and subsequently to each 30 months, until 720th day after vaccination. No animal showed reaction in day zero. In 15th day above 95% of animals revealed reaction in all tests. All the animals presented absence of reactions in CFT, RBT and 2ME tests at 270, 300 and 360 days after vaccination, respectively. Our finding highlighted early response in CFT compared than other conventional agglutination tests. None of animals presented oscillation of titers or reactions in any test after 360 day of study, which enables the use of these tests after this period without interference of antibodies from S19 vaccine origin between 3 and 8 months in buffalo heifers.

    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

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

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

    About 200 individual sarcocysts were excised from 12 samples of cattle beef from five countries (Argentina, Brazil, Germany, New Zealand, Uruguay) and tentatively identified to species or cyst type on the basis of their size and shape and cyst wall morphology. Genomic DNA was extracted from 147 of these sarcocysts and used initially for PCR amplification and sequencing of the partial mitochondrial cytochrome c oxidase subunit I gene (cox1) in order to identify the sarcocysts to species and/or sequence type. In addition, seven Sarcocystis sinensis-like sarcocysts collected from the oesophagus of water buffaloes in Egypt were examined at cox1 for comparative purposes. Based on the results from the cox1 marker, selected sarcocyst isolates from both hosts were further characterised at one to three regions of the nuclear ribosomal (r) DNA unit, i.e. the complete 18S rRNA gene, the complete internal transcribed spacer 1 (ITS1) region and the partial 28S rRNA gene. This was done in order to compare the results with previous molecular identifications based on 18S rRNA gene sequences and to evaluate the utility of these regions for species delimitations and phylogenetic inferences. On the basis of sarcocyst morphology and molecular data, primarily the cox1 sequences, four Sarcocystis spp. were identified in the samples of cattle beef. Twenty-two microscopic sarcocysts (1 × 0.1 mm) with hair-like protrusions were assigned to Sarcocystis cruzi, 56 macroscopic sarcocysts (3-8 × 0.5 mm) with finger-like protrusions were assigned to Sarcocystis hirsuta and 45 and 24 microscopic sarcocysts (1-3 × 0.1-0.2 mm) with finger-like protrusions were assigned to Sarcocystis bovifelis and Sarcocystis bovini n. sp., respectively. Sarcocysts of S. cruzi were identified in samples of beef from Argentina and Uruguay; sarcocysts of S. hirsuta in samples from Argentina, Brazil, Germany and New Zealand; sarcocysts of S. bovifelis in samples from Argentina and Germany; and

    Full Text Available Water buffaloes ( Bubalus bubalis, are capable of becoming infected with Neospora caninum and Toxoplasma gondii, contributing to disease dissemination. The incidence of these antibodies was assessed in sera of water buffaloes, using an immunofluorescent antibody technique (IFAT. Any possible influence of breed or age of the buffaloes was investigated, besides assessment of sera antibody titres of any dogs and humans that were in close contact with the tested animals. Serum samples were taken from water buffaloes (n=411, dogs (n=8 and humans (n=14, from buffalo dairy farms in the São Paulo State, and tested. Of the samples of buffalo sera tested, 56.0% were reactive ( >1:200 to N. caninum and 49.9% were reactive ( >1:64 to T. gondii. Of all, 33.9% of the buffaloes presented antibody titres for both protozoon parasites. Of the canine serum samples, 25.0% presented titres ( >1:50 for N. caninum and 62.5% for T. gondii ( >1:16. The human serum samples did not show detectable antibodies for N. caninum when using a >100 limit titre for positive findings. The obtained data allows the conclusion that the protozoan parasite N. caninum, as well as T. gondii, are widely disseminated in the water buffalo herds assessed and, apparently, the factors breed and age do not interfere with frequency of N. caninum positives among adult female buffaloes. When concerning T. gondii, female buffaloes of 5 to 6 years of age showed more frequent presence of specific antibodies.Bubalinos são susceptíveis à infecção por Neospora caninum e Toxoplasma gondii, contribuindo assim para a disseminação destes protozoários na natureza.

    Although buffalo population is about 1/10 of that of cattle, buffaloes interest a larger human population, especially in the east countries. For this reason, this species is of great economic importance. Two main species of buffalo are found in the world: the Asiatic (water) buffalo (Bubalus bubalis) and the African buffalo (Syncerus caffer). These two different species have both two different sub-species differing in diploid number but interbreeding within the same genus. The water buffalo, ...

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

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

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

    This study was conducted to determine the chromium content of different feedstuffs, their estimated requirement, and effect of dietary Cr supplementation on nutrient intake, nutrient utilization, growth performance, and mineral balance in buffalo calves during summer season. Levels of Cr was higher in cultivated fodder, moderate in cakes and cereal grains, while straw, grasses, and non-conventional feeds were poor in Cr content. To test the effect of Cr supplementation in buffalo calves, 0, 0.5, 1.0, and 1.5 ppm of inorganic Cr were fed to 24 buffalo calves. Buffalo calves were randomly assigned to four treatments (n = 6) and raised for 120 days. A metabolic trial for a period of 7 days was conducted after 3 months of dietary treatments. Blood samples were collected at fortnight interval for plasma mineral estimation. The results suggested that dietary Cr supplementation in summer did not have any affects (P > 0.05) on feed consumption, growth performance, nitrogen balance, and physiological variables. However, dietary Cr supplementation had significant effect (P 0.05) balance and plasma levels of other trace minerals. The estimated Cr requirement of buffalo calves during summer season was calculated to be 0.044 mg/kg body mass and 10.37 ppm per day. In conclusion, dietary Cr supplementation has regardless effect on feed consumption, mass gain, and nutrient utilization in buffalo calves reared under heat stress conditions. However, supplementation of Cr had positive effect on its balance and plasma concentration without interacting with other trace minerals. PMID:23963742

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

    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.

    The digenetic trematodes, Fasciola gigantica and Gigantocotyle explanatum, belonging to the family Fasciolidae and Paramphistomidae respectively, have been often found to concurrently infect the liver of Indian water buffalo Bubalus bubalis, causing serious pathological damage to the vital organ, incurring huge economic losses. In the present study the soluble gene products of both F. gigantica and G. explanatum were analyzed by 2 dimensional polyacrylamide gel electrophoresis. The soluble proteomic profile revealed considerable similarity as well as differences in the size, distribution pattern, total number, the isoelectric point (pI) and molecular weight (Mr) of the resolved polypeptide spots. The maximum number of polypeptide spots with a molecular weight range of >10 to 160 kDa were recorded with a pI range of 7-9 followed by pI range of 5-7, 9-10 and 3-5 in both the parasites. However, considerable variation was recorded in the Mr of the polypeptides belonging to each pI range. The genetic heterogeneity could be an obvious contributing factor for such differences but some polypeptides appeared to be conserved in the two species. The molecular similarities and the habitat preference by these worms may be a consequence of microenvironmental cues that guide these flukes to reach their habitat through different routes and establish a successful host-parasite relationship.

    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 (Pcows. Highest mRNA expression of IGFBP-5 was observed around 300 days of lactation followed by 200 and 250 days (Pmilk as compared with Sahiwal cows during lactation in ELISA. Animals having history of short lactation length (short lactating animals) showed higher levels of IGFBP-5 expression (at

    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.

    The smallmouth buffalo Ictiobus bubalus is a native benthivore to floodplain lakes in the Yazoo River Basin, USA. Based on evidence from other benthivorous fish studies we hypothesized high biomasses of I. bubalus contribute to poor water quality conditions. We tested this hypothesis in shallow (< 1.5 m) 0.05 ha earthen ponds at three stocking biomasses over a 10-week period during the summer of 2012. The most notable results from the permutational multivariate analysis of variance suggest I. bubalus at high and moderate biomasses significantly (p < 0.05) enhanced turbidity and suspended solid levels while decreasing Secchi depth. Our results suggest that effects of I. bubalus on water clarity may have considerable ecological implications in natural habitats such as shallow floodplain lakes.

Clinically relevant anatomic structures were identified and labeled at each level in the corresponding images (MR and anatomic slices. MRI images were used to identify the bony and soft tissue structures of the stifle joint. The articular cartilage appeared with hyperintense signal and separated from the subcondral bone by gray line (moderate signal intensity. It is difficult to differentiate between the synovia, infrapatellar fat body and the articular cartilage because they appeared with hyperintense signal. The meniscial, femoropatellar and cruciate ligaments recognized as moderate signal intensity. However, the collateral and intermediate patellar ligaments, the common tendon of the Mm. extensor digitorum longus and peroneus tertius as well as the menisci and the medial patellar fibrocartilage appeared with hypointense signal. The knowledge of normal anatomy of the buffalo stifle joint would serve as initial reference to the evaluation of MR images in this species.

    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

    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. PMID:24506047

    2008-11-01

    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

    Bubali Cornu (water buffalo horn, WBH) has been used for thousands of years in traditional Chinese medicine (TCM) as an effective treatment for heat. In the present study, we have carried out a metabolomics profiling study on plasma and urine samples to explore potential biomarkers and determine how WBH exerts its antipyretic effects in yeast-induced pyrexia at a metabolomic level. Ultra-high performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS), together with multivariate statistical analysis, was used to detect and identify potential biomarkers associated with pyrexia and with WBH treatment. In total, sixteen endogenous metabolites were identified in plasma samples and twenty-one metabolites were detected in urine samples. The biomarkers identified in this study, using metabolic pathway analysis (MetPA), are involved in glycerophospholipid, arachidonic acid, amino acid, sphingolipid, and purine metabolism, all of which are disturbed in rats with pyrexia. As a result, WBH affect arachidonic acid metabolism and oxidative stress in yeast-induced pyrexia rats chiefly. The present study determines the important substances underlying the antipyretic efficacy of WBH at a metabolic level. It might pave the way for further investigations into the mechanisms of action of other animal horn-derived traditional Chinese medicines (TCMs). PMID:27384078

After 24 to 26 hours of maturation, IVF was done with swim-up separated frozen-thawed buffalo spermatozoa at 1×106 mL-1 in modified Tyrodes medium (TALP). At 24 to 26 hours post insemination, the oocytes were co-cultured with granulosa cell monolayer in droplets containing culture medium. The proportion of cleaved oocytes that developed to blastocyst stage within 9 days after commencing co-culture with granulosa cell monolayer was then evaluated. In experiment 1, the proportion of cleaved oocytes that developed to blastocyst stage was higher (12.8%) at 1.0 μg/mL PRL though not significantly different from the control (9.1%). In experiment 2, addition of 5% BFF to the maturation medium had significant increase in the cleavage rate of oocytes compared to the control (30.7% vs. 21.7%, P<0.05), but did not influence the proportion of cleaved oocytes that developed into blastocysts;addition of 5% BFF+1.0 μg/mL PRL to the maturation medium had a cleavage rate of 38.1%, with 14.0% of the cleaved oocytes developing to blastocysts (P<0.05). In conclusion, the results indicate that the addition of appropriate amounts of prolactin and bovine follicular fluid to the maturation medium will enhance the maturation of immature buffalo oocytes with their subsequent development to the blastocyst stage.%对催乳素和牛卵泡液在水牛卵母细胞体外成熟中的作用进行了探讨. 来自屠宰场水牛卵巢的卵母细胞和卵丘细胞复合体,在含体积分数为5% CO2的培养箱中培养24~26 h,然后通过体外受精测定

    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.

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

  1. Strategies to overcome seasonal anestrus in water buffalo.

    2016-07-01

    Reproductive seasonality in buffalo (Bubalus bubalis) is characterized by behavioral, endocrine, and reproductive changes that occur over distinct periods of the year. During the nonbreeding season (spring and summer), the greater light-dark ratio (long days) suppresses estrus behavior and the occurrence of ovulation. Anestrous buffaloes have insufficient pulsatile of LH to support the final stages of follicular development, and subsequently, estrus behavior and ovulation do not occur, limiting reproductive efficiency, especially in artificial insemination (AI) programs. A number of therapeutic strategies designed to synchronize follicular wave emergence and ovulation have allowed for the use of AI throughout the year, overcoming seasonal anestrus in buffalo. These therapies also improve reproductive performance by increasing the service rate and pregnancy per AI in buffalo herds, regardless of reproductive seasonality. PMID:27157389

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

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

    A molecular epidemiological survey of Cryptosporidium from water buffalo (Bubalus bubalis) in the Northern Territory in Australia was conducted. Fecal samples were collected from adult farmed (n = 50) and wild buffalo (n = 50) and screened using an 18S quantitative PCR (qPCR). Positives were typed by sequence analysis of 18S nested PCR products. The qPCR prevalence of Cryptosporidium species in farmed and wild buffalo was 30 and 12 %, respectively. Sequence analysis identified two species: C. parvum and C. bovis, with C. parvum accounting for ~80 % of positives typed from the farmed buffalo fecal samples compared to 50 % for wild buffalo. Subtyping at the 60 kDa glycoprotein (gp60) locus identified C. parvum subtypes IIdA19G1 (n = 4) and IIdA15G1 (n = 1) in the farmed buffalo and IIaA18G3R1 (n = 2) in the wild buffalo. The presence of C. parvum, which commonly infects humans, suggests that water buffaloes may contribute to contamination of rivers and waterways with human infectious Cryptosporidium oocysts, and further research on the epidemiology of Cryptosporidium in buffalo populations in Australia is required.

    Experimental evidences support a direct role for leptin in immunity. Besides controlling food intake and energy expenditure, leptin was reported to be involved in the regulation of the immune system in ruminants. The aim of this work was to highlight the expression of leptin receptor (LEPR) on Bubalus bubalis immune cells using a multi-approach assessment: flow cytometry, confocal microscopy and gene expression analysis. Flow cytometric analysis of LEPR expression showed that peripheral blood monocytes were the predominant cells expressing LEPR. This result was corroborated by confocal microscopy and RT-PCR analysis. Moreover, among lymphocytes, LEPR was mainly expressed by B lymphocytes and Natural Killer cells. Evidence of LEPR expression on buffalo blood leukocytes showed to be a good indicator of the responsivity of these cells to leptin, so confirming the involvement of leptin in buffalo immune response.

    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.

    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 (Pspace 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.

  14. Metabolism of intra muscularly injected 45Ca in a buffalo (Babalus bubalis) during late lactation

    International Nuclear Information System (INIS)

    Intramuscular injection of 45CaCl2 in to a buffalo during late lactation suggested an immediate transport of the injected 45Ca into blood followed by its secretion or excretion into milk, urine and faeces. Calcium from blood is concentrated several folds by mammary secretory cells before secretion. Over a period of 162 hr after administration of 45Ca, the cumulative activity of 45Ca (per cent of injected dose) secreted or excreted in the milk, urine and faeces was 11.75, 4.26 and 52.07 per cent, respectively. Subsequently secretion of 45Ca (per cent of injected dose) into milk decreased to 0.22 per cent at 1001 to 1200 hr after administration of 45CaCl2. (author). 10 refs., 3 figs., 1 tab

  17. Reproductive cycles of buffalo.

    Perera, B M A O

    2011-04-01

    The domestic water buffalo (Bubalus bubalis) has an important role in the agricultural economy of many developing countries in Asia, providing milk, meat and draught power. It is also used in some Mediterranean and Latin American countries as a source of milk and meat for specialized markets. Although the buffalo can adapt to harsh environments and live on poor quality forage, reproductive efficiency is often compromised by such conditions, resulting in late sexual maturity, long postpartum anoestrus, poor expression of oestrus, poor conception rates and long calving intervals. The age at puberty is influenced by genotype, nutrition, management and climate, and under favourable conditions occurs at 15-18 months in river buffalo and 21-24 months in swamp buffalo. The ovaries are smaller than in cattle and contain fewer primordial follicles. Buffalo are capable of breeding throughout the year, but in many countries a seasonal pattern of ovarian activity occurs. This is attributed in tropical regions to changes in rainfall resulting in feed availability or to temperature stress resulting in elevated prolactin secretion, and in temperate regions to changes in photoperiod and melatonin secretion. The mean length of the oestrous cycle is 21 days, with greater variation than observed in cattle. The signs of oestrus in buffalo are less overt than in cattle and homosexual behaviour between females is rare. The duration of oestrus is 5-27 h, with ovulation occurring 24-48 h (mean 34 h) after the onset of oestrus. The hormonal changes occurring in peripheral circulation are similar to those observed in cattle, but the peak concentrations of progesterone and oestradiol-17β are less. The number of follicular waves during an oestrous cycle varies from one to three and influences the length of the luteal phase as well as the inter-ovulatory interval. Under optimal conditions, dairy types managed with limited or no suckling resume oestrus cyclicity by 30-60 days after calving

    2010-02-01

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

    The smallmouth buffalo Ictiobus bubalus Rafinesque (Catostomidae) is native to North American waterways and occasionally grown in pond aquaculture. Species of Myxobolus Bütschli, 1882 have been reported from the gills, integument, and intestinal tract of buffalo fish, although there is ambiguity in some host records. In the summer of 2013, thirteen adult smallmouth buffalo were seined from a 0.1-acre (0.04-hectare) experimental research pond at the Thad Cochran National Warmwater Aquaculture Center in Stoneville, Mississippi, USA, and examined for the presence of parasitic infection. Two previously unknown species of Myxobolus were observed parasitising the gills. Plasmodia of the two species differed from each other in both size and shape. Morphologically the two species were distinct from one another and from other Myxobolus spp. previously reported from buffalo fish. Myxospores of Myxobolus ictiobus n. sp. were spherical and measured 12.7-14.5 (13.9 ± 0.4) µm in length and 10.7-13.6 (12.5 ± 0.7) µm in width with a thickness of 10.3-14.8 (12.6 ± 2.3) µm. Polar capsules measured 5.6-7.4 (6.6 ± 0.4) µm in length and 3.7-4.9 (4.5 ± 0.8) µm in width and each contained a coiled polar filament with 5-6 turns. Myxospores of Myxobolus minutus n. sp. were circular in shape and measured 7.4-9.6 (8.6 ± 0.7) µm in length and 7.5-9.9 (8.8 ± 0.7) µm in width with a thickness of 6.5-7.3 (6.7 ± 0.3) µm. Polar capsules measured 3.6-4.9 (4.3 ± 0.3) µm in length and 2.8-3.8 (3.3 ± 0.3) µm and each contained a coiled polar filament with 5-6 turns. Supplemental 18S rRNA gene sequencing identified unique sequences for each isolate. Phylogenetic analysis of 18S rRNA sequences demonstrated a strong clustering of both isolates with other species of Myxobolus from cypriniform fish. PMID:27307169

    Lowland Anoa has become endangered due to hunting and human activity. Protection and breeding of endangered species in a controlled environment is the best way of conservation. However, it is not possible to adopt this approach for all endangered species because of the cost involved and the ever-increasing number of critically endangered species. In consideration of these limitations to the conventional conservation methods, we established a primary cell culture of endangered buffalo (Lowland Anoa, Bubalus quarlesi), for the preservation of this biological resource. In addition, we introduced human derived, mutant cyclin dependent kinase 4 (CDK4), Cyclin D, and telomerase reverse transcriptase (TERT) into the primary cells. The successful introduction of these three genes was confirmed by western blot with specific antibodies, and enzymatic activity. We also showed that the expression of mutant CDK4, Cyclin D, and TERT allows us to efficiently establish an immortalized cell line, with an intact chromosome pattern, from Lowland Anoa. To the best of our knowledge, this study is the first investigation that established an immortalized cell line of an endangered wild animal species. PMID:27449922

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

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

    Full Text Available 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.

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

  11. Reproductive status and synchronization of oestrus for predetermined insemination of Philippine carabaos (swamp buffalo) raised by smallholder farmers

    International Nuclear Information System (INIS)

    There is an urgent need to improve size, and meat and milk productivity of the Philippine carabao, a swamp type of water buffalo (Bubalus bubalis), through crossbreeding with the riverine type. Studies were conducted to assess the reproductive status of carabaos raised by smallholder farmers, determine conception rates of buffaloes to artificial insemination (AI) through oestrus synchronization, and examine the patterns of plasma progesterone in cyclic and acyclic carabao heifers. Approximately 20% of carabaos raised by smallholder farmers were diagnosed pregnant by rectal palpation. This low pregnancy rate may be due to a combination of factors such as the failure to submit for examination carabaos exhibiting external signs of pregnancy, the deliberate postponement of breeding for working females, the inability of bulls to gain access to carabaos in oestrus which are tethered at night, or the high incidence of anoestrus or suboestrus. The reproductive problems in non-pregnant animals were cystic (19.5%), infantile (25.7%), and dormant ovaries (51.3%), and pathology of the uterus and cervix (3.5%). Both feeding and management practices in different locations influenced the nutritional status of female carabaos examined. Animals in good body condition were either cycling or pregnant. A 30-40% conception rate was achieved by synchronization of oestrus and insemination with frozen semen at 72 and 96 h later. Based on progesterone radioimmunoassay and rectal palpation of the ovaries, anoestrus in carabao heifers was due either to a failure of cycling animals to exhibit oestrus or those with inactive ovaries.

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

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

    Flow cytometry and Laser Tweezers Raman spectroscopy have been used to investigate Nili-Ravi buffalo (Bubalus bubalis) sperm from different samples (fresh, stained, sorted and frozen-thawed) of the flow-sorting process to optimize sperm sex sorting procedures. During the sorting and freezing-thawing processes, the two detection methods both indicated there were differences in mitochondrial activity and membrane integrity. Moreover, a dispersive-type NIR (Near Infrared Reflection) use of the Raman system resulted in the ability to detect a variety of sperm components, including relative DNA, lipid, carbohydrates and protein contents. The use of the Raman system allowed for PCA (principal components analysis) and DFA (discriminant function analysis) of fresh, stained, sorted and frozen-thawed sperm. The methodology, therefore, allows for distinguishing sperm from different samples (fresh, stained, sorted and frozen-thawed), and demonstrated the great discriminative power of ANN (artificial neural network) classification models for the differentiating sperm from different phases of the flow-sorting process. In conclusion, the damage induced by sperm sorting and freezing-thawing procedures can be quantified, and in the present research it is demonstrated that Raman spectroscopy is a valuable technology for assessing sperm quality.

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

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

    Full Text Available The development of effective diagnostic tools will be essential in the continuing fight to reduce schistosome infection; however, the diagnostic tests available to date are generally laborious and difficult to implement in current parasite control strategies. We generated a series of single-chain antibody Fv domain (scFv phage display libraries from the portal lymph node of field exposed water buffaloes, Bubalus bubalis, 11-12 days post challenge with Schistosoma japonicum cercariae. The selected scFv-phages showed clear enrichment towards adult schistosomes and excretory-secretory (ES proteins by immunofluorescence, ELISA and western blot analysis. The enriched libraries were used to probe a schistosome specific protein microarray resulting in the recognition of a number of proteins, five of which were specific to schistosomes, with RNA expression predominantly in the adult life-stage based on interrogation of schistosome expressed sequence tags (EST. As the libraries were enriched by panning against ES products, these antigens may be excreted or secreted into the host vasculature and hence may make good targets for a diagnostic assay. Further selection of the scFv library against infected mouse sera identified five soluble scFv clones that could selectively recognise soluble whole adult preparations (SWAP relative to an irrelevant protein control (ovalbumin. Furthermore, two of the identified scFv clones also selectively recognised SWAP proteins when spiked into naïve mouse sera. These host B-cell derived scFvs that specifically bind to schistosome protein preparations will be valuable reagents for further development of a cost effective point-of-care diagnostic test.

    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

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

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

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

    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 insemination. Thus, the embryonic loss was 8.7%, 11.11%, and 12.00 % in W, SC, and C cows, respectively. Pregnancy rates decreased between 44.32% and 50.51% when mastitis occurred during Day -15 before to Day +30 after AI, compared with 59.22% in the uninfected cows. The diameter of CL was greater (P < 0.05) in W than SC and C cows starting at Day 9 postbreeding onward. Likewise, P4 concentrations on Days 9 through 25 after AI were greater (P < 0.05) in W cows as compared to SC and C cows. Positive correlations (P < 0.01) were found on Days 5, 9, 12, 16, 21, and 25 after AI between CL diameter and P4 concentrations. Similar trend was found among CL diameter, P4 concentrations, and pregnancy rate. Accordingly, incidence of mastitis revealed suppression to both CL diameter and function leading to significant reduction in pregnancy outcome of buffalo cows. PMID:27177967

    The gullet worm (Gongylonema pulchrum) has been recorded from a variety of mammals worldwide. In an earlier study, we demonstrated two separate transmission cycles in cattle (Bos taurus) and wild mammals in Japan based on nucleotide sequences of the ribosomal RNA gene (rDNA) and cytochrome c oxidase subunit I (cox-1) region of mitochondrial DNA of multiple isolates of different origins. Our earlier study additionally demonstrated two major cox-1 haplotypes of G. pulchrum prevalent in cattle in Japan. In the present study, we collected G. pulchrum from cattle and goats (Capra hircus) in Alashan League, Inner Mongolia, China; Gongylonema aegypti from spiny mice (Acomys dimidiatus) in the Sinai Peninsula, Egypt; and Gongylonema neoplasticum from a black rat (Rattus rattus) in Okinawa Island, Japan, to analyze their genetic relationships with G. pulchrum in Japan. The gullet worms from Alashan League had almost identical rDNA nucleotide sequences and two cox-1 haplotypes as seen in G. pulchrum from the cattle in Japan. The two rodent Gongylonema spp. had distinct rDNA nucleotide sequences compared with those of G. pulchrum; only the 18S and 5.8S rDNA sequences showed high identities at 97.2-98.7%, while the remaining sequences were less than 75% identical. The 18S, 5.8S, and 28S rDNA sequences of the two rodent Gongylonema spp. showed nucleotide identities of 99.8% (1811/1814), 100% (158/158), and 98.9% (3550/3590), respectively. The cox-1 regions showed 91.6% (338/369)-92.1% (340/369) identities, with completely identical amino acid sequences. The genetic diversities of three distinct Gongylonema spp. and their possible intraspecific genetic variation may allow us to resolve the taxonomic position of Gongylonema spp. which display few obvious morphological differences from their congeners. Consequently, the Gongylonema isolate from water buffaloes (Bubalus bubalis) in Nepal reported in our previous study is concluded to be a new species, and Gongylonema nepalensis n

  20. The physiological mechanism of low purine derivative excretion in urine of buffaloes

    International Nuclear Information System (INIS)

    Three cattle calves (Bos Taurus) and three buffalo calves (Bos bubalus) were weaned after receiving colostrum and reared by bottle-feeding of milk. During the first month the animal did not have access to solid food. Urinary purine derivative (PD), concentration, basal PD excretion and glomerular filtrate rate (GFR) were determined during fasting and feeding. After one month the animals were given access to solid feed (urea-treated rice straw 80% and molasses 20%) to stimulate rumen development. At three months of age, while the solid food was given, urinary PD, basal PD excretion and GFR were again determined. Urinary PD excretion both during fasting and milk feeding did not differ significantly between buffaloes to cattle during the period of milk feeding (P > 0.05), but there were highly significant differences between cattle and buffaloes after 3 months of age and two months of access to solid feed (P < 0.01). The GFR was lower in buffaloes than cattle on both milk fed and solid feed periods. It is suggested that the lower GFR found in buffaloes may be the reason for the differences as PD stay longer in the blood to give more time for recycling to the rumen when the rumen is developed and are then metabolized by bacteria. Whether permeability of PD from blood to rumen is an additional factor is not known. (author)

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

Also, the antioxidant enzymatic activities of superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase were significantly (P < 0.05) increased in all the treatment groups compared to the control group. Therefore, the present study clearly establishes that heat stress ensues oxidative stress in bubaline oocytes which triggers the induction of antioxidant enzymatic defense system for scavenging the ROS.

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

    Full Text Available Chinese buffalo is of swamp type, mainly distributed in countryside of 18 provinces in southern China. China has the third population of buffalo in the world. There are 22.75 million buffaloes in China in 2005, representing 17.37% of all cattle in the whole country. Historically Chinese buffalo is mainly used for drought since their milk production is very low with an annual milk yield of 500-700 kg. Therefore, it is important to improve them to change into dairy buffalo through crossbreeding with exotic river type dairy buffalo breeds. Murrah and Nili-Ravi, the most famous river type dairy buffalo breeds in the world, were introduced from India and Pakistan in 1957 and 1974, respectively and used to crossbreed with indigenous Chinese buffalo for genetic improvement. The effect is very prominent that the performance of crossbred has been improved significantly after several decades and the milk yield reaches 1200-2000 kg. Recent years in countryside of China, buffalo rearing has been changed from extensive and dispersive model in the past into specialized small or medium dairy herd model for the present along with the rapid development of dairy buffalo breeding and the model of dairy buffalo breeding sub-district has been formed. This article introduces briefly that the system of dairy buffalo breeding as well as producing, processing and selling of buffalo milk under the current condition and the prospects of dairy buffalo development in countryside of China.

    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.

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

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.

    2009-01-01

    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.

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

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

Gallbladders and liver sample were collected from 9 Water buffaloes and 2 Cattle, divided into three groups, and studied by means of light microscopy and histochemical techniques. It was found that G1 had parasitic infection, G2 showed inflammation and no typical lesion was seen in G3. Previous observations firmly indicated that the gallbladder epithelial injury took before gallstone formation and the consequences of these cellular changes played a contributory role in causing gallstone. The same observation was noted in our findings in Water buffaloes, but no sign of gallstone formation. The results of bile analysis showed clearly the difference between the Water buffaloes and Cattle, that the β-glucuronidase, cholesterol and calcium levels were lower in Water buffaloes than those in Cattle, however, the bilirubin level was lower in Cattle.

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.

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

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

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

    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.

  2. Perspectives of fetal dystocia in cattle and buffalo

    Directory of Open Access Journals (Sweden)

    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.

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

    The Corps of Engineers Buffalo District conducted a demonstration of equipment for dredging contaminated sediments. Several thousand cubic yards of sediment were removed from outside the Buffalo River Federal navigation channel limits using three dredge types: (1) open bucket, (2) enclosed bucket, and (3) submersible pump. The effectiveness of a silt screen deployed downstream of the dredge to reduce suspended sediment transport was also evaluated. Extensive sediment and water column monitoring and sampling were conducted during the 2-week demonstration as part of the effort to determine sediment resuspension rates and contaminant releases associated with the dredging operations. Water column samples were analyzed for total suspended solids, total organic carbon, PCBs, PAHs, metals, ammonia, and pH. A water column bioassay test using Daphnia magna was also performed to assess toxicity effects of the dredging operation. Results of this study were used to assess and refine techniques and laboratory tests that have been previously developed by the Corps of Engineers to predict sediment resuspension rates and contaminant releases. In another phase of the study, the Bureau of Mines demonstrated the use of polyelectrolytes for rapid removal of suspended solids from a dilute dredged material slurry.

  13. Molecular Dynamics Studies on the Buffalo Prion Protein

    CERN Document Server

    Zhang, Jiapu

    2015-01-01

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

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

    Full Text Available Meat characteristics of mature swamp buffalo fed with two different ratios of roughage and concentrate feed was studied. Twelve draught buffaloes with an average weight of 350 kg were randomly divided into two treatments and kept individually in pens. The concentrate:roughage ratio (based on dry matter was 50:50 (T1 or 30:70 (T2, respectively. All buffaloes were slaughtered at a body weight of 500 kg (± 25 and M. longissimus dorsi was removed in order to study meat quality. The meat quality in terms of color, pH and conductivity values were not significantly different between the groups. Meat color in terms of L* (lightness showed that LD of T2 group was significantly lighter when compared with T1 (P0.05. In conclusion, meat characteristic traits of buffalo fed concentrate to roughage in ratios of 50:50 or 30:70 were similar.

    River buffalo chromosome 1 (BBU1) is a sub-metacentric chromosome homologous to bovine chromosomes 1 and 27. In this study, we constructed a new framework radiation hybrid (RH) map from BBU1 using BBURH5000 panel adding nine new genes (ADRB3, ATP2C1, COPB2, CRYGS, P2RY1, SLC5A3, SLC20A2, SST, and ZDHHC2) and one microsatellite (CSSM043) to the set of markers previously mapped on BBU1. The new framework RH map of BBU1 contained 141 markers (55 genes, 2 ESTs, 10 microsatellites, and 74 SNPs) distributed within one linkage group spanning 2832.62 centirays. Comparison of the RH map to sequences from bovine chromosomes 1 and 27 revealed an inversion close to the telomeric region. In addition, we ordered a set of 34 scaffolds from the buffalo genome assembly UMD_CASPUR_WB_2.0. The RH map could provide a valuable tool to order scaffolds from the buffalo genome sequence, contributing to its annotation. PMID:26535622

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

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

    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.

    2013-12-01

    The Buffalo River discharges into Lake Erie near the upper end of the Niagara River. The lower 9.2 km of the river has been designated as a Great Lakes Area of Concern due to environmental problems associated with poor water quality, degraded riparian and river habitat, and contaminated sediments. The U.S. Army Corps of Engineers maintains a navigational channel at a depth of 6.7 m below mean lake level by periodic dredging. In 2011, extensive dredging took place within the upper portions of the river to remove some of the most contaminated sediments. This dredging resulted in both widening and deepening of the channel. The Buffalo River's gradient is low and current velocities generally are Buffalo River reversing its flow. The largest episodic lake-driven flow reversals were found during strong westerly wind events that setup an elevated water level at the eastern (Buffalo) end of the lake. Lower amplitude flow reversals could also be associated with subsequent Lake Erie surface seiches or other phenomena. They also occur during times when no seiche conditions are present. The interaction between river flow and reverse (lake-driven) flow was investigated using Acoustic Doppler Current Profilers (ADCPs), temperature sensors, and water level recorders deployed for the past five years at various locations in the lower 9 km of the river. The collected data record the periodic reversals associated with Lake Erie seiches, but also reveal an oscillation within the river. This 'river seiche' has a period of ~2 hours and occurs continuously, persisting even during high flow events and during times of strong lake-driven flow reversals. To better understand the characteristics and behavior of this 'river oscillation', time-series plots and Fourier power spectra were produced from the ADCP data. These data show that the magnitude of the oscillation is on the order of 5-10 cm s-1. There are three coherent spectral peaks with significant power above the noise. These peaks have

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

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

    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.

    Full Text Available Biosaf is a thermostable live yeast concentrate (Saccharomyces cerevisiae Strain Sc47. The trial was carried out on 35 buffalo cows subdivided in 3 groups: Group A (Control with farm standard diet; Group B (with the same diet, added with 6g Biosaf/day; Group C (with the same diet, added with 60g Biosaf/day. The trial started within the first month from calving (1st month of lactation up to the 8th month of lactation. The mean values for milk production during 8 months of trial are 8.95, 8.95 and 8.91 liters/d, respectively in Group A, B and C, without significant differences among groups. The protein percentage increased in groups receiving Biosaf. The effect was significant (P<0.05 in Group B and C at the 4th, 5th and 8th month of lactation in comparison to Control Group and in Group B at 4th month of lactation in comparison to Control Group: this indicates that Biosaf integration really increases milk protein and consequently mozzarella yield.

  7. Cumulative Environmental Management Association : Wood Buffalo Region

    International Nuclear Information System (INIS)

    The recently announced oil sands development of the Wood Buffalo Region in Alberta was the focus of this power point presentation. Both mining and in situ development is expected to total $26 billion and 2.6 million barrels per day of bitumen production. This paper described the economic, social and environmental challenges facing the resource development of this region. In addition to the proposed oil sands projects, this region will accommodate the needs of conventional oil and gas production, forestry, building of pipelines and power lines, municipal development, recreation, tourism, mining exploration and open cast mining. The Cumulative Environmental Management Association (CEMA) was inaugurated as a non-profit association in April 2000, and includes 41 members from all sectors. Its major role is to ensure a sustainable ecosystem and to avoid any cumulative impacts on wildlife. Other work underway includes the study of soil and plant species diversity, and the effects of air emissions on human health, wildlife and vegetation. The bioaccumulation of heavy metals and their impacts on surface water and fish is also under consideration to ensure the quality and quantity of surface water and ground water. 3 figs

    Full Text Available Several experimental and clinical reports indicated the oxidative stress-mediated adverse changes in vital organs of human and animal in fluoride (F toxicity. Therefore, the present study was undertaken to evaluate the therapeutic effect of buffalo (Bubalus bubalis epiphyseal (pineal proteins (BEP and melatonin (MEL against F-induced oxidative stress in heart, liver, and kidney of experimental adult female rats. To accomplish this experimental objective, twenty-four adult female Wistar rats (123–143 g body weights were divided into four groups, namely, control, F, F + BEP, and F + MEL and were administered sodium fluoride (NaF, 150 ppm elemental F in drinking water, MEL (10 mg/kg BW, i.p., and BEP (100 µg/kg BW, i.p. for 28 days. There were significantly P<0.05 high levels of lipid peroxidation and catalase and low levels of reduced glutathione, superoxide dismutase, glutathione reductase, and glutathione peroxidase in cardiac, hepatic, and renal tissues of F-treated rats. Administration of BEP and MEL in F-treated rats, however, significantly P<0.05 attenuated these adverse changes in all the target components of antioxidant defense system of cardiac, hepatic, and renal tissues. The present data suggest that F can induce oxidative stress in liver, heart, and kidney of female rats which may be a mechanism in F toxicity and these adverse effects can be ameliorated by buffalo (Bubalus bubalis epiphyseal proteins and melatonin by upregulation of antioxidant defense system of heart, liver, and kidney of rats.

  14. Measurement of purine derivatives in the urine of some ruminant species

    International Nuclear Information System (INIS)

    The application of published high performance liquid chromatography (HPLC) methods for the determination of PD in urine of cattle, sheep, buffaloes (Bubalus bubalis) and arabian camels (Camelus dromedarius) was investigated. Urine was taken from two water buffaloes, two camels, three cows and four sheep, all fed at maintenance level. Total nitrogen content in urine was determined using a micro-Kjeldahl procedure. Allantoin, uric acid and creatinine levels were determined colorimetrically while xanthine and hypoxanthine concentrations were determined by HPLC. Relative proportion of allantoin ranged from 74 ± 7 to 91 ± 1% in camels and cattle, respectively. Uric acid proportion was very low in camel urine (1.7 ± 1) but ranged from 3.7 ± 3 to 9.2 ± 1% in sheep and cows, respectively. Xanthine + hypoxanthine ranged from 11 ± 3 to 25 ± 7% in buffalo and camels, respectively. Total PD:Creatinine ratio (mol/mol W0.75) was 118 ± 15, 46 ± 17, 37 ± 9 and 33 ± 5 for cattle, camels, buffaloes and sheep respectively. The adoption of a single method for the simultaneous detection of all derivatives proved difficult due to elution of polar coextractives at the same retention times as the peaks of allantoin, uric acid and creatinine.

    2014-12-01

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

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

  17. The role of MC1R gene in buffalo coat color

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

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

    The present study aimed to investigate the association of cholinesterase activity with trypanosomosis in buffaloes. Thirty-three clinical cases of trypanosomosis in water buffaloes, found positive for trypomastigotes of T. evansi on blood smear examination, were divided into two groups based on clinical manifestations. Twenty diseased buffaloes revealing only common clinical signs were allocated to Group I, while the remaining 13 buffaloes showing common clinical manifestations along with neurological disturbances were allocated to Group II. Twelve clinically healthy buffaloes, free from any haemoprotozoa infection, were kept as healthy control (Group III). Blood samples were collected from buffaloes of all three groups to determine serum cholinesterase activity. Compared to buffaloes of healthy control group, cholinesterase activity in T. evansi-infected buffaloes of Group I and II was significantly (Pbuffaloes exhibiting neurological disorders and no neurological disorders. Summing up, reduced cholinesterase activity seems to be associated with the pathogenesis of natural T. evansi infection and its clinical manifestations in buffaloes possibly by evading immune response. Further studies are warranted on association of cholinesterase activity in T. evansi-infected buffaloes with neurological disorders. PMID:27369572

    Full Text Available In 4 x 4 LSD, four graded Murrah buffalo bulls (6 yrs; 353 ± 8.26 kg were fed four iso-nitrogenous complete rations comprising of jowar stover (CR1, maize stover (CR2, red gram straw (CR3 and black gram straw (CR4 as roughage source and concentrate mixture in 60:40 proportion, to study the effect of feeding complete rations on nutrient utilization. The DM intake (kg/d was similar in all the groups. The digestibility coefficients of DM, OM, CP, EE, CF, NDF, ADF, Cellulose and Hemi-cellulose were significantly (P<0.01 higher in buffalo bulls fed CR2 while NFE digestibility was higher (P<0.05 in CR3 when compared to those fed other complete rations. All the animals were in positive N, Ca and P balances. Further, the % DCP and % TDN were significantly higher (P<0.01 in buffalo bulls fed CR2. It could be concluded that maize stover compared to other crop residues could be a superior roughage source for inclusion in complete rations for feeding buffalo bulls.

    Full Text Available This paper describes a cross-sectional study in buffaloes of district Toba Tek Singh from April, 2009 to March, 2010 which aimed to identify prevalent species of Eimeria (E and risk factors associated with subclinical coccidiosis. Overall prevalence of Eimeria in buffaloes was 49.6%. Six species of Eimeria were identified in total infected buffaloes. E. bovis was the commonest one among the species identified during survey followed in order by E. zuernii, E. canadensis, E. ellipsoidalis, E. alabamensis and E. cylindrica. Peak prevalence was observed in August. Wet season was found favorable for Eimeria. Odds of finding oocysts were higher in young stock and females (P<0.05 as compared to those of adults and males respectively. Among management and husbandry practices, five variables were found significantly associated with status. These included housing system, feeding system, watering system, floor type and herd size. Open housing system, trough feeding, tap watering, partially cemented floor type and smaller herds showed protective effect against coccidiosis with Odds of detection being higher in closed housing system, ground feeding, pond watering, non-cemented floor type and larger herd size, respectively. Body condition and breed of buffaloes were not found associated with prevalence of Eimeria. Value of feeding in troughs, provision of clean tap water, cementing floor of farms in reducing the extent of infection should be communicated to farmers. Appropriate monitoring and control of the disease is advisable.

    This study was conducted to investigate the normal somatic cell count (SCC) and to define subclinical mastitis in Murrah buffaloes. Data were collected from 60 clinically normal buffaloes stationed at five farms of Chitwan Nepal and Buffalo Research Center, Hissar, India. Somatic cell count was measured using the Newman-Lampert staining technique. The upper limit of SCC was determined >or=200 000/ml of milk based on the mean +/- 2SD of a total SCC. Abnormal data of the SCC was repeatedly removed, which lie beyond the values of more than mean + 2SD until all the data come to lie within (mean + 2SD). Averages of SCC of right front and right hind quarters were significantly higher than left front and left hind quarters. Nearly 94% of California mastitis test (CMT) negative quarters were having somatic cells >or=200 000/ml. The mean SCC of CMT positive quarter was significantly higher (P CMT negative quarters. Subclinical mastitis was diagnosed on the basis of samples with SCCs >or=200 000/ml with positive bacterial cultures. Subclinical mastitis was found in 21.7% buffaloes and 8% of the quarter foremilk samples. Neutrophil counts were significantly higher in subclinical mastitis milk. PMID:16626405

    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.

    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 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.

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

    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.

    2010-02-01

    Full Text Available Researches were conducted on a biologic material, a buffalo livestock, in different lactating stages and their physico-chemical parameters were determined: fat, protein, lactose, unfat dry substance, density, pH, temperature. Regarding the variation of these components, researches conducted emphasized differences determined by those conditions specific to reference seasons. Individual analysis on the buffalo livestock in the study, emphasized significant differences: fat 8.59-9.36%, protein 5.16-5.31% respective of lactation. Microbiologic determinations mainly envisioned: the number of somatic cells (NSC, number of total germs (NTG Positive Coagulanzo Stafilococii, Listeria, Salmonella, determinations which lay at the basis of the assessment of buffalo milk quality. The positive Coagulanzo stafilococus was absent, excepting sample number 15 (2 germs/ml and sample number 22 (4 germs/ml; Salmonella was absent. Regarding the total number of germs: values between 1.0-1.8 germs/ml were obtained. The detection of this microbiologic parameter in the composition of buffalo milk provides information regarding the hygienic conditions of their production and handling. Correlations between the number of somatic cells, milk production and composition are employed in dairy buffalo farms, in order to assess losses caused by mastitis and the implementing of certain measures for the control of these diseases. On the other hand, correlations between the number of somatic cells and milk composition prove useful in establishing milk processing behaviour, as the practice of setting milk-raw matter prices according to the number of somatic cells in the milk is becoming increasingly more frequent in developed countries.

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

    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. PMID:27155729

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

    Full Text Available Biodiversity is the basic indicator, which expresses the durability and stability zone in direct relationship with the environment and life. Biodiversity monitoring both quantitatively and qualitatively puts us in contact with reality environment and its stability, because biodiversity is constantly changing. Only by measuring the biodiversity we can perceive the sudden chances, which influence directly our life in order to interfere with redesigning the media by ecological reconstruction. The application of biotechnologies to buffalo breeding is paramount to remedy the existing situation. The most numerous Romanian buffalos are the Carpathian type, with valuable gene resource, well adapted to the cold climate for buffalo. Results of artificial insemination in this species are influenced by the quality of semen used. We know that there are periods in which sperm are immobile, so it is important to test the ability of sperm fertilized. This test can be performed in vitro using direct or indirect methods. Utilization of Polamski scale principle remains present, but can be improve and combine with Milovanov resistance and “in vitro” capacitating methods. For determination of fertilizing power we use “in vitro” capacitation methods: direct method, indirect method and “swim-up” technique who are obligatory in E.U. We use this tests because Polamski scale can’t be applied, knowing that an immobility of buffalo semen in some conditions is a characteristic of this semen, semen that can be recovery on the normal parameters. Milovanov resistance test have restricted efficiency because NaCl solution have a negative effect over the sperms. Semen charges testing with these new methods they present a good fertilizing power. This test is easier to realize and takes of decision is faster.

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

  13. Reproductive performance of dairy buffalo receiving supplements of urea-molasses multi-nutrient block (UMMB)

    International Nuclear Information System (INIS)

    Buffalo are the predominant dairy animal in India. However, poor nutrition limits their productive and reproductive efficiency. The effects of supplementary feeding of urea-molasses multi-nutrient blocks (UMMB) prepared by an easy 'cold method' were assessed during different phases of reproduction in dairy buffalo. Supplementary feeding during the pre-partum period improved postpartum reproductive efficiency in terms of days to first oestrus (34 vs 48 d) and conception rates (30% vs 0%) when compared to unsupplemented controls. The effects of UMMB supplementary feeding were more pronounced in buffalo kept in rural areas by marginal farmers than in those kept on organized farms, due to the differences in the basal diet in each system. Pre-partum UMMB supplementation also improved the post-partum milk yield. Supplementation with UMMB in buffalo calving at a young age induced a higher proportion (71% vs 14%) to exhibit oestrus during the first 50 days post-partum, compared to unsupplemented controls. Milk yield was greater and peak milk yield was maintained for a longer duration with UMMB supplementation during the post-partum period. Supplementation with UMMB for 30 days in buffalo with delayed onset of puberty induced oestrus in 33% of heifers during the summer season and in 93% of the heifers during the winter season. Similarly, in anoestrus adult buffalo, UMMB supplementation induced ovarian activity in 40% of buffalo during the summer season and in 90% buffalo during the winter season. In addition, UMMB supplementation was shown to increase the effect of pregnant mare serum gonadotropin (PMSG) used for induction of oestrus in anoestrus and delayed pubertal buffalo. Medicated blocks could be successfully used for easy dispensing of herbal drugs to decrease placenta retention or reduce nematode parasite burdens in buffalo. Overall, UMMB supplementation improved milk production and reproductive efficiency in dairy buffalo and could be easily adopted by marginal

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

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

    Full Text Available An indirect enzyme-linked immunosorbent assay (ELISA was evaluated for the detection of Brucella antibodies in milk from water buffalo (Bubalus bubalis Linnaeus, 1758. The test accuracy was evaluated on milk samples from the Campania Region in Italy. A total of 100 negative samples were collected from 10 officially brucellosis-free herds in Salerno Province, while 30 positive samples were collected from 3 herds in Caserta Province, where animals gave positive results to the official tests and it was here that Brucella abortus biovar 1 had been isolated. Test sensitivity was 100%, with a confidence interval (CI of 90.8%-100%, while specificity was 98% (CI 93%-99.4% on individual milk samples. To simulate bulk milk samples from herds infected at various levels of infection, dilutions from 1:10 to 1:100 of positive milk samples in negative milk were also used. The probability of detecting antibodies in positive milk samples was higher than 50% up to a dilution of 1:50 in negative milk. Considering the average national water buffalo herd size, the probability of identifying infection in a water buffalo herd by bulk milk testing is 50% (CI 33.1%-66.9% in the worst case scenario of a single infected animal contributing to the bulk milk.

    Full Text Available Buffalo farming in Italy is traditionally oriented towards mozzarella cheese production and over the last decade it has been rapidly increased. As a result, intensive techniques and mechanisation of farm activities have been introduced. Those sudden changes in rearing techniques have aroused a general concern about buffaloes welfare and its possible consequences on products quality.Human-animal interactions are recognized to have an impact on productivity, behaviour and welfare, particularly in dairy farms, where the milking process involves a close interaction with a human handler. Focusing on the first month of lactation, this preliminary study aimed at evidencing buffalo behavioural responses to machine milking. Relationship between behaviour and oxytocin administrations, often performed to allow milk let down, has been also investigated. The experiment included 8 multiparous and 6 primiparous buffaloes, calving in the same period. Starting from the first entrance in the milking parlour, the animals were followed two days/ week during the morning milking for the first 5 weeks of lactation. Behaviour observation was performed following a “focal animal sampling” (continuous recording technique. Proportional frequencies of the following behaviours were calculated: kicking, stepping, defecating, urinating, vocalizing, pulling the teat cup off the teats. The exogenous oxytocin administration at milking was recorded. Pearson Chi-Square test was used to verify the presence of differences between primiparous and multiparous cows’ behaviour at milking. Cochran’s Q test was used to assess the variability of behaviour over time and a binomial regression was performed in order to verify the correlations between animal behaviours and the need to administer oxytocin. Considering lactation number, every behavioural pattern in primiparous cows, except for stepping, resulted to be more frequently performed (36.67% vs 24.36% for kicking; 5% vs 2

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

    The volume-surface average diameter of fat globules are larger in buffalo milk than in cow milk and the volume frequency distribution in buffalo milk is more balanced. The globule size was affected by animal, stage of lactation, and test day. An interesting contrast compared to cow milk is the negative correlation between diurnal fat yield and globule size.

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

    Directory of Open Access Journals (Sweden)

    Tiago Marafiga Degrandi

    2014-06-01

    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.

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

    Directory of Open Access Journals (Sweden)

    L C Cruz

    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

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

    2016-01-01

    A PCR-based survey of hemoprotozoa parasites detected Babesia bigemina, Theileria orientalis and Trypanosoma theileri among cattle and water buffalo in Vietnam, and a new Babesia sp. closely related to Babesia ovata was detected in cattle only. In addition, Theileria annulata and Trypanosoma evansi were not detected in both cattle and water buffalo. Phylogenetic analysis detected T. orientalis MPSP genotypes 3, 5, 7 and N3 in cattle and 5, 7, N1 and N2 in water buffalo. Additionally, water buffalo-derived T. theileri CATL sequences clustered together with a previously reported cattle-derived sequence from Vietnam. This is the first report of a new Babesia sp. in cattle, and T. orientalis MPSP genotype 7 and T. theileri in water buffalo in Vietnam. PMID:27149894

    Full Text Available The present study was designed to determine the quarter-wise comparative prevalence of mastitis in buffaloes and crossbred cows. Milk samples collected from 50 dairy buffaloes and 50 crossbred cows were tested for subclinical mastitis by Surf Field Mastitis Test. In addition, all milk samples were processed for isolation and identification of pathogens. In buffaloes, overall prevalence of subclinical mastitis was 27%, clinical mastitis 4% and blind quarters 10%. In crossbred cows, subclinical mastitis was observed in 36%, clinical mastitis in 5.5% and blind quarters in 8% quarters. Prevalence was higher (32% in hindquarters of crossbred cows than those of buffaloes (29%. Among the isolates, Staphylococcus aureus showed the highest (45% frequency, followed by Streptococcus agalactiae (23%, E. coli (18% and Bacillus spp. (14% in buffaloes. In case of crossbred cows, Staphylococcus aureus , Streptococcus agalactiae , E. coli and Bacillus spp. were isolated from 48, 30, 13 and 8% milk samples respectively.

  18. Effect of gamma irradiation on the unsaponifiable matter components of cows, buffaloes and goats milk fat

    International Nuclear Information System (INIS)

    Fresh cow's, buffalo's and goat's milk were treated with gamma-irradiation from a cobalt-60 source at safe doses (250, 500 and 750 krad) in addition to raw milk of the same types. Results indicate that total hydrocarbon was much lower in unsaponifiable matter (unsap. m) of goat's raw milk fat than that of cow's and buffalo's. Unsap. m of cow's milk fat consisted of ten hydrocarbon compounds, while it consisted of eight hydrocarbon compounds in both buffaloes and goats ones. Moreover, the unsap. m of goat's milk had the highest total sterols followed by buffalo's and cow's, respectively. Cholesterol represents the predominant sterol compound of the unsap. m in all kinds of raw milk fat. The application of ascendent doses of gamma irradiation increased total hydrocarbons and decreased total sterols (particularly cholesterol compounds) of unsap. m of both buffalo's and goat's milk fats, while the reverse trend occurred with cow's milk fat

Milk sample was collected from each selected buffalo at day 15 and 60 pp to study milk yield and composition variability between these two breeds. Buffaloes were categorized for the ease of data analysis and comparisons into four groups, viz., S15 (Surti buffaloes 15th day pp, S60 (Surti buffaloes 60th day pp, M15 (Mehsani buffaloes 15th day pp, and M60 (Mehsani buffaloes 60th day pp. Results: There were 37.20% and 25.03% significant (p≤0.05 increase in mean test day milk yield (TDMY of S60 and M60 as compared to S15 and M15 groups, respectively. The mean TDMY of Mehsani buffalo was 99.19% and 81.53% significantly (p≤0.05 higher than Surti buffaloes at day 15 and 60 pp, respectively. The mean fat and protein corrected test day milk yield (FPCTDMY of all the groups was found to be significantly different (p≤0.05 from each other. There was significant (p≤0.05 increase of 1.94 and 3.45 kg in mean FPCTDMY with the progression of lactation between day 15 and 60 pp in Surti and Mehsani buffaloes, respectively. Similarly, the mean FPCTDMY of Mehsani buffaloes were approximately double with 103.27% and 96.36% higher yield as compared to Surti buffaloes at day 15 and 60 pp, respectively. Among milk composition, significant differences were observed for solid not fat (SNF and protein%, whereas fat and lactose% were steady among four groups. The only significant (p≤0.05 difference was observed for SNF in M60 group, which was 8.29%, 6.85%, and 10.70% higher as compared to S15, S60, and M15 groups, respectively.

    Buffalo spermatozoa are comparatively more susceptible to freezing hazards than cattle spermatozoa. In recent times incubation of spermatozoa with cholesterol-loaded-cyclodextrins (CLC) has shown improvements in semen quality in several species. Therefore, this study was undertaken to evaluate the incubation level of CLC at which maximum benefit is derived for the buffalo spermatozoa. For the study, 120 million spermatozoa were incubated in 2, 3 and 4 mg/mL of CLC (Gr II, III and IV, respectively) and cholesterol and phospholipids content, their ratio, flow cytometric evaluation of plasma membrane integrity (PMI), plasma membrane fluidity and extent of cryoinjury (Chlortetracycline, CTC assay) were compared with an untreated control (Gr I). Additionally the ability of cholesterol-loaded-spermatozoa to undergo induced acrosome reaction (IAR) using ionophore calcium (A23187) was evaluated in frozen-thaw samples. Data show a significant and linear increase (CV=0.88) in cholesterol content of spermatozoa in Gr II, III and IV and a significant decrease in phospholipids content at frozen-thaw stage in Gr IV than Gr III spermatozoa. The study revealed a significant improvement in PMI and significant reduction in plasma membrane fluidity and cryoinjury of CLC treated spermatozoa at progressive stages in three groups compared to control. Nevertheless, spermatozoa of Gr II, III and IV were significantly less responsive to ionophore calcium (A23187) than Gr I. This study shows for the first time that incubation of buffalo bull spermatozoa with CLC (3mg/120×10(6)) prior to processing permits greater numbers of sperm to survive cryopreservation while allowing spermatozoa to capacitate and the acrosome to react to AR inducer ionophore calcium (A23187).

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

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

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

    The enzyme-linked immunosorbent assay (ELISA) was evaluated for the diagnosis of Fasciola gigantica infection in cattle and buffaloes. The excretory-secretory (E-S Ag) antigen of F. gigantica adult flukes obtained after invitro incubation was used as an antigen. The test was conducted with 276 sera collected from cattle and buffaloes which included 22 sera each from naturally infected cattle and buffaloes (known positive serum) and with similar number of samples with healthy cattle and buffaloes (known negative serum). The positive results were observed in 18 and 19 of the sera from naturally infected cattle and buffaloes with sensitivity of 81.8 and 86.3 % respectively. Out of 188 serum samples which were found negative on faecal examination 32 (34 %) sera of cattle and 40 (42.5 %) sera of buffaloes were found positive by ELISA respectively. The sensitivity of the test was found to be 91.6 and 95.6 % in cattle and buffaloes respectively.

    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.

    The Buffalo River discharges into Lake Erie near the upper end of the Niagara River. The lower 9.2 km of the river has been designated as a Great Lakes Area of Concern due to beneficial use impairments associated with poor water quality, degraded riparian and river habitat, and contaminated sediments. The U.S. Army Corps of Engineers maintains a navigational channel at a depth of 6.7 m below mean lake level by dredging every 2-3 years. Its low gradient and current velocities that often are Buffalo River reversing flow. These estuarine-like conditions can occur during low flow periods in the river when water levels at the eastern end of Lake Erie rise in response to seiches when persistent winds transport water from west to east increasing water elevation at the Buffalo (eastern) end of the lake. To better understand the interaction between the downriver and upriver (lake-driven) flow, Acoustic Doppler Current Profilers (ADCPs), temperature sensors, and water level recorders have been deployed in the lower 9 km of the river. To map the river and document changes in bottom morphology side-scan sonar surveys have been conducted. Sediment trend analysis (STA) and numerical modeling complement and augment field observations. Changes in grain size distributions derived from the STA show two distinct flow regimes existing in the river with sediments deposited around the mouth of the river re-entrained and transported upriver. Results from numerical modeling using a particle-tracking component also show a similar pattern. Where the two flow regimes intersect, sedimentary furrows have been mapped using side-scan sonar and confirmed by divers. ADCP findings document periodic high flow events in the river related to heavy rainfalls and snow melt as well as the propagation of Lake Erie seiches upriver as far as 9 km. The water level data agree well with ADCP data obtained in the river. The river also exhibits its own seiche with period of ~ 2.0 hours. The hydrodynamics and

    Composition and physico-chemical properties of buffalo and cow milks were compared at their initial pH and during chemical acidification. As compare to cow milk, buffalo milk was richer in caseins and minerals such as Ca, Mg and Pi. Along with these differences, the capacity of buffalo milk to be acidified named buffering capacity was also higher than cow milk. The pH decrease induced aggregation of caseins at their isoelectric pH and solubilisations of Ca and Pi were significant for both mil...

  13. Relationship between length of estrous cycle and progesterone levels and milk production in Egyptian buffaloes

    International Nuclear Information System (INIS)

    Ten non-pregnant and ten pregnant buffaloes were used in the present study and were milked twice daily (7 a.m. and 3 p.m.) whereas milk samples (20 ml) were collected at the morning every 4 days throughout the period from May 2010 to July 2010. At the same time blood samples (15 ml) were collected from every buffalo by puncture of the jugular vein into evacuated tubes. Progesterone concentrations in the first 2 samples were used to determine whether buffaloes were cycling or not. Buffaloes with serum progesterone ≥1.0 ng/ml in at least one of the two samples were considered cycling, and those with both serum samples containing 1.0 ng/ml were considered as an ovulatory /anestrous. Regression of the corpus luteum was considered if serum progesterone was 1.0 ng/ml. Buffaloes with serum progesterone >1.0 ng/ml in at least one of the two samples considered pregnant. The data were statistically analyzed The data revealed that pregnant buffaloes had higher (P<0.01) mean values of serum P4 and milk P4 than non-pregnant buffaloes. At the same time, milk P4 profile was higher (P<0.01) than serum P4 and the ratio between milk P4 and serum P4 in both pregnant and non-pregnant buffaloes. However, milk P4 was 2.4 times higher than that of serum P4 in pregnant buffaloes; while milk P4 was 2.9 times higher than that of serum P4 in non-pregnant buffaloes. Total daily milk yield had higher (P<0.01) mean values than both morning and after milk yield. Morning milk yield had higher (P<0.01) mean values than after milk yield. Step-wise regression analysis show that both serum P4 and milk P4 profiles depended on each other. Either serum P4 or milk P4 profiles can be accurately used for pregnancy detection in buffaloes. In addition, the close correlation between progesterone concentrations in milk and blood plasma suggests that it may be useful to measure milk progesterone in clinical cases of reproductive abnormalities in buffalo.

    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.

    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 (water buffaloes were reactive with single serotypes with low MAT titers, but older animals were reactive with multiple Leptospira strains with variable MAT titers. In addition, antibodies against serogroups Icterohaemorrhagiae and Pomona were detected in both animals. Finally, Leptospira infection was found associated with age and animal grouping, highlighting the impact of management in the persistence of leptospirosis at intensive-type buffalo farm settings in the Philippines. Further investigation and appropriate control strategies are required to prevent leptospirosis from causing risks to public health and economic losses to the water buffalo farming industry.

    Full Text Available 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.

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

    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
