How old does a bull need to be to tell that a cow is in heat. I have a 4 month old bull calf and I'm wanting to AI so I was wondering if he is old enough to chase the cows when they are in heat? So I can tell easier.

That, I don't know because I don't AI. May want to move your thread to the AI Board.How long do the heat detectors stay on/work for?
