wow... missing that many cows, especially those in the 3rd trimester... bet that vet catches a lot of heat... the easiest cows to palpate and know they are bred are those in the last trimester.. just reach in and there is a calf there to feel...
double wow.. to acurately palpate cows and the worst you are ever off is 6 days is unheard of around here.... if we get em within a month around here that is good. sometimes you miss em a week and sometimes 6 weeks... but that is just the way it is here... i have bought cows that were missed by 3 months.. but that is not the norm here.
