    MORPHOLOGICAL AND IMMUNOHISTOCHEMICAL STUDIES ON ANTIGEN ASSOCIATED WITH OVARIAN FOLLICULAR ATRESIA IN BUFFALO (Bubalus bub alls)
    (Karnataka Veterinary Animal And Fisheries Sciences University, Bidar, 2009) SUNILKUMAR PATIL
    More than 50 percent of the worldâ s buffalo population is found in India. The buffalo has a pivotal position in terms of contribution to milk production and Indian rural economy. It is paradoxical that only about 0.1% of the milking buffaloes are capable of producing a good 3500-4000 kg of milk in 305 day lactation period (Misra et al., 1990). This calls for a need for faster multiplication of this elite but small germplasm pool. The constraint in this is the low reproductive efficiency in this species. Various factors that contribute to this are delay in attainment of puberty, poor expression of oestrus making breeding at the appropriate time difficult, higher incidence of early embryonic mortality, longer inter-calving interval, and seasonal variation in fertility. Attempts to increase elite germplasm through assisted reproductive technologies (multiple ovulation and embryo transfer, ovum pickup from live animals, in vitro embryo production and transfer) have not yielded much success. A practical approach with the general assumption that the buffalo is similar to cattle has not yielded any significant favourable results.
