I have smaller numbers so a %age would not be relevant. I synchronise for 1 round of AI and then 1 round with the bull which would fall 21 days after AI and I think 20-22% would be a realistic figure. I do leave the bull in for a 2nd shot at them and sell these PTIC so I know that there will usually be a couple that fall outside of that 1st 21 days. There are factors outside of feed and sexual maturity with heifers, some are just shy breeders and don't know to stand still for the bull to do his work. I use yearling bulls on my heifers and there is variability in their ability to hit the mark the first time with a young lady.Grass quality is likely why. How many others can do better in that short of time and with how many heifers?
