[QUOTE="Lucky_P, post: 1255081, member: 12607"] bse, I don't think length of needle has anything to do with it, but if I had 1.5" needles, I wouldn't throw 'em out. 2013 Spring breeding season - 5 day protocol(1" needle) we got 90%(20 of 22) calving to single AI service. 2014 Spring - essentially the same group of cows (22) same protocol, only about half cycled in. Let the bull have the rest of them, as it was getting hot...calving in 2015 was spread out - 12 calves in the first two weeks, remainder trickling in over the next 6+ weeks. 2015 - same cows, plus a group of 17 mo heifers - results were as I recounted above, most in heat between 36 and 72 hrs... but those 5 tail-enders coming in 5,6,7 days out from CIDR-pull. Will be pulling in the group of 2014 bull-bred cows this coming weekend, just now coming to 45 days post-calving; will hit them all with Estrumate, breed any that come in, then CIDR the rest.
