Had my heifers carried to the vet today to get their bangs vaccines, horns removed and palpated, turns out one of them is 2 months bred she is 11 months old. I insisted them be away from the bull until at least yearling age, what is the chance she will be able to calve? I am upset that I wont only lose the calf but the heifer. The vet said the bangs vac may cause her to slip the pregnancy. She is a black angus bred to a polled hereford bull.
