[QUOTE="Buck Randall, post: 1675639, member: 38590"] There's definitely more labor involved in AI, but daily heat detection isn't really a necessary component of a successful AI program. Synchronize the cows. Monitor for heats for a couple days, then breed the remainder timed AI. Ignore the cows for a while. 25 days after breeding, give them all a GnRH shot. Ultrasound on day 32. Open cows get prostaglandin and heat detection/timed AI. Repeat as necessary. If you hit 60% conception at each round of breeding, you'll have 94% of the herd pregnant with a 64 day breeding season. Not bad. Not necessarily a labor saver, per se, but it concentrates the labor onto scheduled days instead of having to watch cows twice a a day for months and sort individual cows off to breed.
