Sent blood off last week after 2 cows aborted. Vet called back and said blue tongue that I should consider getting rid of the infected ones. Didn't get to talk long to ask many questions but from what I've read it's not contagious since it's from mites and that some cows develop antibodies. Anyone have any experience with this? Would the cows ever carry full term again? Read an article from a Florida university that tested over 200 head and over 40% tested positive. By all appearances the cows are fine. Thoughts??
