[QUOTE="Anonymous, post: 9964"] There have been varying studies done on this and I don't know of a hard and fast rule. The reasons not to vacc. in the first 60 days of preg. are 1) fetal absorption/abortion 2) vaccines unable to protect against abortions in most vulnerable time. A rule of thumb which is used in this area is vaccinate 1 heat cycle before breeding. This way there is no stress on the animals at heat and the pregnancy is protected. Thus if breeding starts June 25, vaccination would be June 4 for cows, June 6 for heifers. Do people actually do this? Many farmers vaccinate in the fall at preg check or weaning, way past the time it'll protect the fetus from abortion. Conveniant, perhaps, but still wasting money in my opinion. If you're cows are really stressed, I'd wait at least 10 day post vax to breed to allow the endogenous steroids to drop enough for conception. Otherwise 3-4 days is probably enough. Clear as mud?
