Ok-I have a 4year old cow that was AIed back in February....palpated mid-May. Vet said she was in the process of aborting the embryo....or had just aborted it. Well, I have seen her come into heat pretty regularly since. Well tonight-she's acting very strange-I would almost think she's in some sort of labor. She's seperate from the rest of the herd, has slight clear mucus, laying down and rolling on side like contractions, then she'll fling her head down towards teats like she's in some discomfort. Also, she is a very tame cow and even charged towards me when I went out ot check her out up closer. Any ideas?
