“…Factors affecting the low success rate were not directly assessed but considered to be multifactor, taking into account field conditions vis-à-vis institutional herds and breed of the recipients. In early trials, pregnancy rates, following non-surgical transfer of in vivo-derived buffalo embryos, were 9.2% (Kurup, 1988), 17.9% (Drost et al, 1988) and 18.3% . In recent years, transfers of 469 in vivo-derived embryos resulted in a 17.0% pregnancy rate (Misra et al, 1994), of which 46 calves were born -a 9.8% success rate and a level similar to this study.…”

“…The multiple ovulation and embryo transfer (MOET) in buffaloes resulted in very low recovery of embryos from the nonsurgical collection. The average number of embryos collected from a donor was 1.0 (Drost et al, 1988 ; Vlakhov et al, 1986 ), 2.0 (Cruz et al, 1991 ) 2.7 (Misra, 1993 ), 4.5 (Kasiraj et al, 1993 ), 1.6 (Kandil et al, 2012 ), 2.7 (Qin et al, 2012 ), and 5.8 (Singh et al, 2015 ). These outputs cover the trials made in Bulgaria, India, Philippines, Egypt, and China (Hufana‐Duran & Duran, 2015 ).…”

Buffaloes are raised by small farm holders primarily as source of draft power owing to its resistance to hot climate, disease, and stress conditions. Over the years, transformation of these animals from draft to dairy was deliberately carried out through genetic improvement program leading to the development of buffalo-based enterprises. Buffalo production is now getting more attention and interest from buffalo raisers due to its socioeconomic impact as well as its contribution to propelling the livestock industry in many developing countries. Reproduction of buffaloes, however, is confronted with huge challenge and concern as being generally less efficient to reproduce compared with cattle due to both intrinsic and extrinsic factors such as poor estrus manifestation, silent heat, marked seasonal infertility, postpartum anestrus, long calving interval, delayed puberty, inherently low number of primordial follicles in their ovaries, high incidence of atresia, and apoptosis. Assisted reproductive technologies (ARTs) are major interventions for the efficient utilization of follicle reserve in buffaloes. The present review focuses on estrus and ovulation synchronization for fixed time artificial insemination, in vitro embryo production, intracytoplasmic sperm injection, cryopreservation of oocytes and embryos, somatic cell nuclear transfer, the factors affecting utilization in various ARTs, and future perspectives in buffaloes.
