we AI on time breeding. 33 day protocol. Works good. We put in cidrs for two weeks, remove them, then 16 days give shot of lutalyce. give gnrh shot and breed 66 hours later. Turn clean-up bulls in 10 days. Breeding ours on November 28. Only drawback is four times thru the chute. Everyone cant afford the best proven bulls but semen for around 20 dollars is worth it.
