Synchronization of Ovulation in Bovines - A Review

Authors(3) :-C. Velladurai, R. Ezakial Napolean, M.Selvaraju

Reproductive performance is the pivotal physiological process for a successful dairy farm. Many dairy herds incur a substantial cut in the economy due to the poor conception rate and proper herd replacement. Proper oestrus detection coupled with efficient insemination technique using quality semen in a healthy uterine environment critically resulted in high rate of reproduction in bovines (Yildiz, 2005). However, first service conception rate to Artificial Insemination (AI) in cows had fallen away from approximately 65 to 40 per cent or lower (Weigel, 2006). Although, the cause has not yet been fully described, the fertility of dairy cows is declining worldwide (Thatcher et al., 2006). Development of Timed Artificial Insemination (TAI) programs allows reduced emphasis on detection of oestrus because all cows are inseminated at a specific time in relation to the hormone injection (Yildiz, 2010).
