A study of 120 days was undertaken to ascertain the effect of mannan-oligosaccharides (MOS) and Lactobacillus acidophilus supplementation on growth performance, nutrient utilization and faecal characteristics in Murrah buffalo calves. Twenty Murrah buffalo calves of 5-7 days old and 31 ± 2.0 kg of body weight (BW) were randomly assigned into four groups. Group I served as the control (CON) in which only basal diet (concentrate mixture and green fodder) was provided, without any supplementation. Mannan-oligosaccharides at 4 g/calf/day were supplemented as prebiotic to Group II (PRE), whereas Group III (PRO) received Lactobacillus acidophilus in the form of fermented milk as probiotic at 200 ml/calf/day having 108  CFU/ml and Group IV (SYN) was supplemented with both MOS and Lactobacillus acidophilus as synbiotic at similar dose...

Anandamide (AEA), an endocannabinoid, has been shown to reduce capacitation and acrosomal exocytosis in human spermatozoa. Because buffalo spermatozoa are highly susceptible to cryopreservation induced damage, AEA was assessed as to whether it could protect spermatozoa from cryo-damage. Six ejaculates from six Murrah buffalo bulls (total 36 ejaculates) were utilized for the study. Each ejaculate was divided into four aliquots; spermatozoa in Aliquot 1 were extended in Tris-Citrate-Egg Yolk and frozen as per the standard protocol...

Resistance to bovine spongiform encephalopathy (BSE) that is significantly associated with insertion/deletion (indel) polymorphisms at two loci (putative promoter and intron 1) on the prion protein gene (PRNP) in cattle has been well documented. Studies suggest that the insertion alleles are related to BSE resistance. Until recently, BSE has never been reported in water buffaloes (unlike cattle). Previous studies have demonstrated that the PRNP gene in water buffalo consists mostly of insertion alleles at both loci; nevertheless, whether or not water buffaloes are genetically resistant to BSE and the role of indel polymorphisms in their resistance status is not clear...

Evaporative cooling during late gestation period improves post-partum reproductive performance in Murrah buffaloes. To prove this hypothesis, sixteen pregnant dry Murrah buffaloes at sixty days pre-partum were selected and divided into two groups of eight animals each. Group 1 of buffaloes (Cooled/CL) was managed under fan and mist cooling during dry period, whereas second group of buffaloes (non-cooled/NCL) remained without the provision of cooling. After parturition, all the animals were managed under evaporative cooling till the end of experimental period...

Binder of sperm-5 (BSP-5) is one of the fertility-associated proteins of cattle seminal plasma. Binding of sperm to the oviductal epithelium is mediated by BSP group of proteins. However, it is not clear, whether this protein is also involved in sperm motility. In the present study, attempts were made to characterize BSP-5 protein in both normozoospermic (NS) and asthenozoospermic (AS) Murrah buffalo (n = 18; Bubalus bubalis), Holstein Friesian (n = 8, Bos taurus) and Jersey cattle (n = 8; Bos taurus) bull seminal plasma and also study its expression pattern in these species...

Elevated intracellular calcium concentration and oxidative damage are two major factors contributing to the poor fertility of cryopreserved spermatozoa. Regucalcin (RGN), also known as Senescence marker protein-30 (SMP-30), is a calcium-binding protein with multiple roles that include calcium homeostasis, anti-oxidative, anti-apoptosis, and anti-proliferation. In Drosophila, RGN is reportedly a putative cold-tolerance gene and a cytoprotective role for RGN against intracellular calcium elevation and oxidative stress was reported in P19 cell lines...

Buffalo DGAT1 (diacylglycerol O-acyltransferase 1) was mainly investigated for the characterization of the gene itself and for the identification of the K232A polymorphism, similar to what has been accomplished in cattle, although no information has been reported so far at the mRNA level. The importance of DGAT1 for lipid metabolism led us to investigate the transcript profiles of lactating buffaloes characterized as high (9.13 ± 0.23) and low (7.94 ± 0.29) for milk fat percentage, and to explore the genetic diversity at the RNA and DNA level...

The excellent adaptation of water buffalo (Bubalis bubalis) to swampy environments means that animals are frequently managed in areas with restricted access for reproductive procedures. The objective of this study was to evaluate the effect of the ovum pick-up (OPU) interval on follicular population, oocyte recovery, oocyte quality and in vitro embryo production. Twelve Murrah buffaloes were subjected to two consecutive dominant follicle reductions, and randomly assigned to either 7-day (n=6) or 14-day (n=6) OPU interval groups...

Cryopreservation causes damage to spermatozoa, and methods minimizing this damage are therefore needed. Although much discussed, seminal plasma removal has become an alternative to improve sperm quality and viability after freezing and has been applied to different species in attempt to obtain good results. The objective of this study was to evaluate semen quality in buffaloes submitted to two methods for seminal plasma removal (filtration and centrifugation). Semen samples were collected from seven Murrah buffalo bulls (Bubalus bubalis) once a week for 8 weeks...
