Last May, I Synchronized and AI'd 22 cows as I normally do every year. Last year however, I did not time AI the cows as I have had some bad results with that. I put the CIDRs in, gave GnRH and pulled them on day 7, giving a shot of lutalyse, and then heat detecting and AI'ng. I was able to catch 17 in standing heat and AI them. I have 16 calves on the ground from those, and I don't think the other settled AI but she is only 1 day late. The other 5, the protocol I used said to AI and give GnRH 84 hours after pulling the CIDR. I only got 1 out of those five.
All in all, 17 out of 22, which is alot better than the timed AI I had done in the past. My thoughts are for this year, any that I don't catch in heat, I will follow up with a second shot of lutalyse 7 days after the first. Thoughts?
