[QUOTE="Bright Raven, post: 1545136, member: 27490"] Thank you for commenting. Your feedback is consistent with my experience. I could have bred later but I am getting old. Lol. Yes. You can breed closer to ovulation. Just be sure you allow the time it takes for spermatozoa to go through "capacitation". I have charted my AI over the last 2 years. I have bred long and short. Both have stuck. Remember this: the limiting factor is the ovum. It is only viable for 6 to 12 hours. If the spermatozoa and ovum do not "rondavo" when both are viable, you will not get a conception. I tend to favor short end breeding. Recent studies suggest spermatozoa have more than a 24 hour viability. BTW: I have bred some only 4 hours after first observed "Standing Estrus" and they stuck. My conception rate is 80 % across the board. [/QUOTE]
