Synchronization and AI Questions Answered

The other week we asked if you had any additional questions for Dr. Cliff Lamb regarding synchronization.  Below is his response to the question.

You can review previous posts here.

Q.) After starting a group of heifers on the 33 day TAI protocol, it was discovered that we need to breed 1 day early. Is it better to remove the CIDR on day 13 or give PGF 15 days(vs 16) after CIDR removal? How much would either change decrease or expected conception rate?

A.) There is no comparative data to know if there would be a decrease in fertility by limiting the CIDR to 13 days or reducing the interval from CIDR removal to 15 days.  However, I do not believe the fertility will decrease sufficiently with either option in a manner that it is noticeable to a producer.  However, given this scenario, I would elect to reduce the length of the CIDR to 13 days rather than reducing the interval from CIDR removal to PGF to 15 days.

 

Special thanks to Cliff Lamb and if you have further questions please send them our way and we will get them answered.
