“…On day 10 after expected oestrus, animals received a total of 200 mg Folltropin, twice daily over 4 days. From 9 yaks, 27 ovulations were detected and 16 embryos were recovered (Sarkar et al. 2007a).…”

Yak and mithun are two domesticated herbivores of high economic importance to the farming community living in highlands. Improved yak and mithun production could significantly enhance the living standards of these highlanders. Over the years, their dwindling numbers have been a cause of serious concern. In view of the lack of knowledge on the reproductive physiology of these ruminants, studies have been undertaken to investigate their reproductive endocrinology in recent years. This paper attempts to present the latest information on the endocrine changes associated with their various reproductive processes viz. growth and puberty, oestrous cyclicity and oestrous behaviour, ovulation, and, pregnancy and parturition. The paper also provides the recent developments on research done towards the enhancement of yak and mithun reproductive efficiencies through endocrine and embryo biotechniques.

“…The world's total yak population is estimated to be approximately 14 million of which more than 90% is in China (Wiener et al 2003). Although yaks are multi-purpose bovids and have large population, the animal suffers from certain inherent reproductive problems, such as (1) late maturity, (2) seasonality of oestrus, (3) long post partum calving intervals and (4) low reproduction, which limits its reproductive efficiency (Sarkar et al 2008a(Sarkar et al , 2008b. So, how to faster multiplication and conservation of yak germplasm have got worldwide attention.…”
