Growth is outcome of interactions among several factors, where thyroid hormones play a key role in coordination of these factors and the information of thyroid hormones in relation to growth in buffalo calves and heifers is not adequate. Thus the study was conducted on Murrah female buffalo calves and heifers, varying in age from newborn to 30 months. The study investigated the serum thyroid pa...

the aims of this study were (a) to establish the occurrence, duration and intensity of behavioral estrus symptoms, and (b) to determine the relationship between behavioral estrus symptoms with the total estrogen profiles in cycling murrah buffaloes (n=10) subjected to doublesynch protocol (0 pgf2α, 2 gnrh, 9 pgf2α and 11 gnrh). after both gnrh injections, estrus and its behavioral signs were de...

The present experiment was conducted on 60 randomly selected dairy units consisting of 116 Graded Murrah,70 Diara type and 121 Non-descript type buffalo cows utilizing the procedure of ‘’stratified random sampling with proportional allocation (Snedecor & Cochran,1967) in and around Patna.Genetic factors were the three different genetic groups of buffaloes viz. Graded murrah,Diara and Non-descri...

AIM To investigate the effect of extended photoperiod on growth rate, hormonal levels, and puberty in Murrah heifers. MATERIALS AND METHODS About 14 Murrah buffalo heifers were divided into normal day photoperiod (NDP; n=7) and extended NDP (ENDP; n=7) groups. The ENDP group was exposed to 4 h of extended photoperiod with artificial light (160 lux) after sunset for 3 months during winter. R...

The water buffalo (Bubalus bubalis) is an important dairy animal on the Indian subcontinent and in Southeast Asian countries. The diversity and differentiation among 12 populations or breeds of buffalo were studied. Data were generated and analyzed from 527 animals belonging to 10 recognized breeds and 2 additional populations of Indian buffalo by using 22 microsatellite loci. Relationships amo...

In this study we evaluated the effects of semen extender supplementation with different concentrations of glutathione (GSH) on buffalo (Bubalus bubalis) bull sperm motility, plasma membrane integrity, viability and DNA integrity as well as in vivo fertility. Semen from three Nili-Ravi buffalo bulls was collected, and qualified semen ejaculates (n=18) were split into five aliquots for dilution (...

AIM The aim of this study was to investigate the effect of commercial egg yolk powder as an alternative to fresh egg yolk on freezability of Murrah buffalo semen. MATERIALS AND METHODS Semen samples (12) from 3 Murrah buffaloes (4 from each bull) with mass motility (≥3+) and total motility (70% and above) were utilized in this study. Immediately after collection, each sample was divided into ...

The objective of this study was to evaluate the effect of the Heatynch protocol on plasma estrogen concentration in Murrah buffaloes and to evaluate if the Heatsynch protocol induces estrus in Murrah buffaloes. All treated animals responded to the treatment by displaying obvious signs of estrus. The mean plasma estrogen concentration among the individual buffalo was 191.9 ± 68.3 pg / ml after E...

The current research concerned in the cloning, sequencing and phylogenetic analysis of inflammatory cytokine (IL-1alpha, IL-1beta, IL-6 and TNF-alpha) genes from swamp buffalo and two bubaline breeds, CB (cross between swamp and riverine type buffalo) and the Bulgarian Murrah buffalo. Multiple sequence comparison showed a high homology between the bubaline breeds, which ranged from 99.3% to 100...

Dimensional characteristics and proportions of live spermatozoa in permanent nigrosin\p=m-\eosinpreparations from the semen samples of Murrah buffalo bulls were studied in different seasons. Between bulls, all the characteristics varied significantly. Between seasons, all the characteristics, except length of head and mid-piece, varied significantly. Environmental temperature and humidity both ...
