[QUOTE="Fire Sweep Ranch, post: 1149310, member: 18809"] You go in too early and you risk the semen dying before the egg is released. The egg is not released until 8 hours after she stops standing, if I remember right. The semen takes just minutes to reach it's destination and wait. The longer the semen sits in the repro track, the sooner it dies. It is living cells, and the freezing process is hard on those cells. Put the semen in too early and it is dead before the egg ruptures. Put it in too late and the egg decays and can not be fertilized. And all that IF there is an egg. So much "if" involved you never really know why she did not get pregnant. Also, a lot depends on the bull and how well he freezes. We have used bulls that we get great conceptions on, and have used bulls that we are lucky if we hit 50% on. That is just the way it works. [/QUOTE]
