[QUOTE="MRRherefords, post: 1487820, member: 26804"] Our Ai tech recommended 60-66 hours post cidr pulling to Ai, we used to ai at 60 hours, but had bad conception rates as our tech said that they were not quite strong enough yet. As for the heifers they recommend between 52-56 hours. so we averaged that out to 54 hours. If they are showing signs of heat pre 63 hours, our tech said still to wait until the 63, that way they will be really strong. We believe they have a better chance of taking that way. And so far I believe that their has only been 1-2 that have not taken due to going out of heat. If anything when we used to do 60, our tech would tell us that she was not quite strong enough and that even another hour or two would have increased conception rate. [/QUOTE]
