Why the wait

[Supa Dexta]

Why is it you wait the 12 hours after standing heat to AI a cow, but the bull breeds her during the standing period obviously? Just don't know the science behind it.

The bull may mount her a few times and deposit quite a bit more, is it because you're only using the small amount, that its best placed that long after?

Egg is not released when she is standing. It is approximately 6 hours after she stands . the semen is viable for 24 hours. the quantity of of semen dis less therefore do you want it deposited with the best chance of conception

To what the others posted, when you AI you deposit the semen in the uterus, the bull just dumps his in the vagina.
