[QUOTE="VaCowman, post: 1615119, member: 33135"] We try to hit it around d90-95. The vet prefers 90, but on occasion we've had to push it to 100. After 95-100d, the calf is usually big enough it has dropped far enough over the pelvis that they are hard to get to. If they take a nose dive, it's easier than if they are head up. Usually at 90-95d, we can get fetal sex on all of our pregnant cows. Our vet is EXTREMELY good at sexing. In the last 5 years, I bet she has only missed 2 at my place. One was in our favor, the other was not, but we got a live calf and that's all that matters. Some folks question why we even bother with sexing, but I feel pretty confident in the vets ability to sex the calves at 90d, and it really is of benefit to me to know how many potential replacements we have coming. If we are heavy on heifers, we can be increasingly critical on the heifers currently in the replacement pen. If we are heavy on bulls, maybe some get through to the breeding pen that might not have if the coming crop wasn't as heavy with replacements. We also sell bred heifers, so we can kind of figure in having a few more of those to sell and budget/plan accordingly. [/QUOTE]
