Abstract:
The synchronization of estrus in post-partum dairy cows involves various methods such as prostaglandins, progesterone-releasing devices like CIDR and PRID, and GnRH analogues. Incorporating a period of progesterone administration enhances the proportion of cows exhibiting estrus within a specific timeframe while maintaining a normal luteal phase. However, the effectiveness of synchronization is influenced by factors related to ovarian activity, including body condition score, age, parity, and negative energy balance. To optimize synchronization outcomes, it is essential to address these variables that may impede post-partum ovarian activity. Managing factors like negative energy balance through appropriate nutrition and tailoring protocols based on age and parity could potentially improve the success of estrus synchronization in these cows.
