I agree with Tinknal. I raised a young jersey bull a few years ago to breed a cow. Bulls, even young ones, are natural troublemakers, always beating something up. I'll never do that again. Spend all year feeding for a few hours of breeding.
Since then I went AI and in 3 different females have gotten 5 pregnancies out of 5 tries. Granted, my cows aren't heavy milkers, which can affect fertility - don't know if a bull fixes that or not.
Can't say I spend alot of time watching them. It's pretty obvious when they're in heat, jumping on each other, clear vaginal discharge. If in heat in the morning, breed that night, if see in heat at night, breed the next morning.
I also figure that the cost of AI is returned by getting a higher quality animal. AI bulls should have some performance testing behind them, along with conformation, well placed udders and teats, etc.
