Follicular wave synchronization for augmenting fertility in dairy cattle

• Repeat breeding is the most serious reproductive problem affecting 30-40% of the total Indian cattle and buffalo population causing a loss of Rs. 40,000-50,000 crores annually.
• At farmer’s level, each missed oestrum is a missed opportunity, as the farmer incurs a loss in the productive life of the animal by 21 days.
• Administration of gonadotrophin releasing hormone (GnRH) analogue (Eg: Buserelin acetate; 8-10 μg, i.m.) on Day 6 of the oestrous cycle (Day 0 = oestrus) resulted in conversion of two wave cycles into three wave ones.
• The conception rate of repeat breeding crossbred with ovulatory disturbances and sub- clinical infections could be increased by 40% by application of follicular wave synchronization technology
