Abstract
In field progeny testing program milk recording at monthly or bimonthly intervals and prediction of first lactation 305-day milk yield (FL305DMY) from these test day yields have been adapted as an alternative to daily milk recording. Wood's incomplete gamma function is the one of the commonly used nonlinear lactation curve model. In recent years Bayesian approach of fitting nonlinear biological models is gaining attention among researchers. In this study Wood's incomplete gamma function was fitted using Bayesian approach using monthly (MTDY) and bimonthly test day (BTDY) yields. The lactation curve parameters thus obtained were used for prediction of FL305DMY. Efficiency of prediction based on monthly and bimonthly test day milk yield were compared using error of prediction. It was found to be 5.78% and 7.59% as root mean square error (RMSE) based on MTDY and BTDY respectively.The Breeding values of 97 Karan Fries sires were estimated using BLUP-AM based on actual and predicted FL305DMY thus obtained. The RMSE was calculated as the difference between estimated breeding values based on actual and predicted yield. It was found that RMSE calculated based on MTDY showed only a marginal superiority of 0.79% over BTDY and showed high degree of correlation with actual yield. Therefore, recording at bimonthly intervals could be an economical alternative without compromising the efficiency.

Abstract
Yak, an economically important bovine species considered as lifeline of the Himalaya. Indeed, this gigantic bovine is neglected because of the scientific intervention for its conservation as well as research documentation for a long time. Amelogenin is an essential protein for tooth enamel which eutherian mammals contain two copies in both X and Y chromosome each. In bovine, the deletion of a fragment of the nucleotide sequence in Y chromosome copy of exon 6 made Amelogenin an excellent sex-specific marker. Thus, an attempt was made to use the gene as an advanced molecular marker of sexing of the yak to improve breeding strategies and reproduction. The present study confirmed that the polymerase chain reaction amplification of the Amelogenin gene with a unique primer is useful in sex identification of the yak. The test is further refined with qPCR validation by quantifying the DNA copy number of the Amelogenin gene in male and female. We observed a high level of sequence polymorphisms of AMELX and AMELY in yak considered as novel identification. These tests can be further extended into several other specialized fields including forensics, meat production and processing, and quality control.

Abstract
In the present study, we report the distribution of true to type and atypical Nili-Ravi buffalo, a vulnerable dairy type riverine breed of North India and its underlying genetic structure. Out of total investigated buffaloes 73.5% had bilateral wall eyes while 5.4% had unilateral wall eyes and 21.1% had no wall eyes. 41.15% of Nili-Ravi buffaloes maintained in the breeding farm were having typical true to the type characteristics (both eyes walled, white markings in forehead, muzzle/chin, all the four legs and tail) while only 28.5% of Nili-Ravi buffaloes were true to the type under field conditions. Genotypic data were generated in four groups of Nili-Ravi buffalo (FMTNR--Typical Nili-Ravi from farm; FMANR--Atypical Nili-Ravi from farm; FDTNR--Typical Nili-Ravi from field; FDANR--Atypical Nili-Ravi from field) at 16 microsatellite loci. Comparative genetic analysis of various groups of Nili-Ravi buffaloes with Murrah revealed significant between group differences with an estimated global F(ST) of 0.063. Pair-wise F(ST) values ranged from 0.003 (between FDTNR and FDANR) to 0.112 (between FMTNR and FDTNR). Phylogenetic analysis and multi-dimensional scaling revealed clustering of FDTNR and FDANR together while FMTNR and FMANR clustered separately with Murrah in between farm and field Nili-Ravi buffaloes. Based on the results, the paper also proposes three pronged strategy for conservation and sustainable genetic improvement of Nili-Ravi buffalo in India.

Abstract
Yak is one of the most important economically useful animals for highlanders. The decline in the yak population demands effective measures for conservation and multiplication of elite germplasm. In vitro production of embryos and their cryopreservation and transfer to suitable recipients for production of elite calves may contribute to fulfill the objectives. The work was conducted at the National Research Center on Yak over a period of 3 years. The ovaries of slaughtered animals were used for collecting oocytes through aspiration of follicles followed by slicing of ovaries in the conventional method. Trials were conducted using 7 cyclic parous yaks for ultrasound-guided ovum pickup (OPU) at Nyukmadung farm (2700 m above mean sea level). The technique followed was similar to that in buffaloes with slight modification. Categories of oocytes classified A (2–3 layers of cumulus) and B (at least one layer of cumulus) obtained through the processes were subjected to in vitro maturation using standardized maturation medium (TCM-199 + 10% follicular fluid + sodium pyruvate + l-glutamine + 10% heat inactivated oestrus cow serum + pFSH + 17β oestradiol). The frozen-thawed yak sperm were capacitated using the swing-up method before their incubation with matured oocytes using BO medium. Oocytes matured for 24 h were washed 5 to 6 times with BO medium and then co-incubated with in vitro capacitated spermatozoa (0.1 to 0.25 million) for fertilization (8–10 oocytes per group) in 100-µL droplets of BO medium under mineral oil in 35-mm Petri dishes and placed in a CO2 incubator (5% CO2, 90% RH) at 38.5°C for 16 to 18 h. The presumed zygotes were washed several times in mCR2aa (modified Charles Rosenkrans) washing medium and then cultured in culture medium for 7 days on original beds of granulosa cells. The rates of maturation and fertilization of oocytes collected by conventional and OPU technique were comparable (Table 1). This may be attributed to greater numbers of good quality oocytes recovered in the conventional method. Embryos developed up to the stage of compact morula and blastocysts (24.66% through conventional and 22.73% through OPU) were cryopreserved using the vitrification method for further study. Thirteen embryos were transferred non-surgically to one each of 13 yak recipients; 5 became pregnant and only 1 recipient transferred with a cryopreserved-thawed embryo, developed through OPU, delivered one male calf, leading to the first successful production of an IVF yak calf in the world. The present findings are suggestive of using the OPU technique for in vitro embryo production, though resulting in lower numbers of transferable embryos (Table 1), because availability of ovaries for conventional IVF is a major constraint in yak.
