Hormone-based Technology to Synchronize for Ovulation in Dairy Cattle

Problems on reproductive efficiency of dairy cows are one of the most important problems for dairy producers. Controlling and synchronizing ovulation has become a routine reproductive management tool for dairy producers.

The steroid-based synchronization of ovulation protocol developed in BIOTEC laboratory has produced a good synchronization of follicular waves and sufficient synchronization of ovulation time, these bring to a good protocol for timed artificial insemination (timed-AI). Field trials showed that this protocol can improve the conception rates in repeat-breeding dairy cows and also overall reproductive efficiencies in dairy cow herds.

With good performance and cost-effectiveness, this protocol has been transferred to and implemented in a number of dairy co-operatives and industries, such as Wangnamyen Dairy Co-operative, Phimai Dairy Co-operative, Namfon Farm and Charoen Pokphand Foods PCL, including over 1,000 smallholder farmers.
