[QUOTE="novatech, post: 530591, member: 5494"] Do these heifers share any genetic blood line? If so, they could all be late maturing, or share something in their genetic make up that is contributing to this. Do all the heifers seem to be the nervous type? Nervous cattle do not lend themselves to AI very well. When you work them through the pens is it done calmly? Heifers selected for AI should be trained early to work through the chutes. One bad apple in the bunch can get the rest of them screwed up when it comes to nervousness. I have seen cattle go from standing heat completely shutting down their cycle in mid stream because of nerves. These same cattle breed just fine when placed with a bull. No matter what the cause is this trait something you want to pass along by continuing to try and AI them? [/QUOTE]
