I was chatting with a friend who breeds cows and he said if you palpate a cow within a week or so after ovulating it can cause her to abort. With mares is there a time when you should not palpate a mare because it could cause her to abort, like the 1st week? Just wondering.
There have been a variety of studies in the equine that have clearly demonstrated that there is no increase in pregnancy loss related to multiple palpations (or ultrasounds) post-ovulation during pregnancy. Interestingly, there was a paper that suggested lower pregnancy rates associated with repeated palpation pre-ovulation, although I am a little skeptical of that in view of how many palpations are performed on mares when transported and frozen semen is used, and yet good pregnancy rates still seen (I cannot remember who did the research, but I think it was a while ago).
