over the past 5 years when we haven't sold any large groups of females for breeding so the only cows leaving have been for 'real' cull reasons the cull rate has been minimal, with a defined breeding season (march 25th thru may 25th, give or take a day or two either way) we have averaged around 95% bred, with those AI'd once averaging >85% settled to that service. For me, the fertility, production and quality of my herd continues to improve, year to year we don't make big changes to the program though I expect within the next few years to reduce the AI component to a minimal amount with home raised sires doing the majority of the breeding. Keep in mind we are doing this out of synch with nature by calving in jan/feb, breeding in mar/april in order to supply yearling bulls that have adequate size and maturity to breed 25 commercial cows in their first year, if we weren't looking to sell bulls I would scrap january calving and go to april/may. I don't think we're doing anything special, folks are free to follow or disagree with my methods, it may be madness to some but it does have method!! I don't think there's anything too complicated about raising beef cattle, we keep it very simple and straightforward, give them access to the best quality feed you can, expect them to get bred, calve themselves, own the calf and raise it, then do it all again, year after year, they're not pets, don't make excuses for 'favorites' (been down that road before, if they can kick you in the a$$ once they can do it again, and they will!) I'm sorry I don't have reams of stats to back up what we do and why we do it, but I do know, thanks to Jeanne I have an additional $1350 in my pocket
