EXECUTIVE SUMMARY

ICAR-National Research Centre on Yak is the premier research organization exclusively engaged in research and development of yak (Poephagus grunniens L). Institute was established in 1989 at Dirang, West Kameng district of Arunachal Pradesh to make an in-depth study on traditional yak rearing and to formulate future plans, strategies and programs for overall improvements and sustainable development of yak husbandry in the country.

ORGANIZATIONAL STRUCTURE
The Director is the highest authority for research strategy formulation and administration with the help of Institute Management Committee (IMC), Research Advisory Committee (RAC), Institute Research Committee (IRC) and other functional committees constituted by the ICAR. Research and development activities are mainly done through different scientific section like Animal Genetics &Breeding, Animal Nutrition, Animal Physiology and Reproduction, Livestock Production & Management, Animal Health, Livestock Product Technology and Veterinary Extension Education. The institute has infrastructure consisting of central facilities like Nyukmadung yak farm, Library, Central Laboratory, Central Instrumentation Facility, AKMU Cell, Estate and Maintenance Section etc. Administrative functions viz., purchase, establishment, store etc. is looked after by the Administrative Officer, where, finance section is under the Assistant Finance & Account Officer. Institute has present strength of Director, 06 scientists, 05 technical, 08 administrative and 15 skilled supporting staff as on 31st December’2020.

BUDGET OUTLAY
The financial outlays of the Institute in terms of actual expenditure and budget sanctioned for the financial year 2020-21 was Rs. 8, 93, 03, 307.00

RESEARCH ACHIEVEMENT
Effect of weaning age and starter protein levels on performance of yak calves
Sucking calves without restriction of milk feeding from dams results digestive disturbances most frequently due to overfeeding. Moreover it is economically less viable. It also lengthens calving intervals although records in this regards in yak is scanty. Effect weaning age and dietary protein levels in calf starters was studied and observed that the weaning yak calves at 2-3 month age with supplementation of high protein calf starter is beneficial for profitable yak rearing at high altitude.

Maize production potentiality for sustainable livestock production
Production potentiality of maize carried out through cultivation of six varieties of maize in different altitude and found out-standing growth for African Tall (fodder variety) and Dirang local (grain variety) in mid altitude (Dirang, 4500 ft above msl); however, the productivity in other varieties viz. sweet corn, QPM (Shaktiman & HQPM-1) and baby corn were comparatively low irrespective of altitude. Complete substitution of normal maize with QPM in the concentrate ration of yaks indicated beneficial effects in both growing and lactating yaks.

Awareness and monitoring of Foot and Mouth Disease (FMD)
A total of 323 animals were vaccinated (277 yaks, 3 hybrids and 70 cattle were vaccinated) in different yak tracts of Arunachal Pradesh. For screening of FMD virus, total 89 serum samples, including 36 yak, 29 yak-cattle hybrids and 21 cattle samples, were collected from different pastures and farm of Arunachal Pradesh.

Detection of anthelmintics resistance in GI nematodes of high altitude animals
Internal parasites in yaks are one of the major health problems in both free ranged and farmed yaks. Considering its economic importance detection of anthelmintic resistance in GI nematodes of yak with other high-altitude ruminants was studied and found no resistance against benzimidazole in GI nematodes of yak, yak cattle hybrids and cattle irrespective of their managemental system and different anthelmentics showed 100% efficacy on faecal egg count reduction test (FECRT).

Ex-situ conservation of yak germplasm and its reproduction
Fresh sperm ejaculates from fertile yaks were collected and evaluated for its concentration, motility and morphology. Evaluation of the cryopreserved yak semen found to be the best in with Tris extender containing vitamin E alone or in combination with Vitamin C. During this report period a total of 1230 semen straw were prepared, evaluated and preserved at -1960C in liquid nitrogen for future use. Superovulation of yaks with a combination of FSH and LH (Stimufol®), and PMSG (Folligon®) alone, were found effective for superovulation and recovery of yak embryos with the best results by the use of Folligon (@ 1500 IU) for Arunachali yaks.

Assessment of Thermo-adaptability in Yaks housed in CGI roofed shelters:
Heat tolerance tests, based changes in physiological responses of the animals in relation to its surrounding microclimate indicated that yaks experience heat stress when housed inside a CGI roofed animal shelter during summer months at an altitude of 2750m above msl under semi-intensive system of rearing.

Development of value added cheese from yak milk
Cheddar style-yak milk cheese from yak milk was prepared with standardized procedure and stored at 7±1°C for 150 days. Cheese samples were evaluated for physicochemical, antioxidant activity, textural, microbial and sensorial changes at defined interval during storage. Physicochemical, microbiological, and texture parameters of yak milk cheese affected with the ageing of cheese. The antioxidant activity enhanced significantly with the advancement of storage period. Sensory evaluation indicated that all the sensory attributes improved with the storage period. Yak milk cheese could be stored up to four months with optimum sensory attributes.

Nutrients profiling for the milk of Arunachali yak
The nutrient composition and physicochemical properties of Arunachali yak milk reared under farm conditions were evaluated for exploring the prospects of product diversification through their value addition. It was observed 15.63-19.63% total solids with 5.29-8.73% fat, 3.45-4.27% protein and 0.64-0.82% ash. The pH, titratable acidity (% lactic acid) and density (g/cm3) of yak milk ranged 6.47-6.63, 0.128-0.161 and 27.9-37.1, respectively. The Fat, solid non fat and protein of yak milk was significantly (p
