I have an odd question. It is to us anyway, but we don't have much experience in dairy cattle. We have an 8 m.o. Jersey heifer that we have had for about 2 months. Her name is Belle and she is wonderful. I was out in the lot with her today seeing if she liked to eat a Triscuit (she did!) and my DH noticed that one quarter of her udder looked like it was kindof full. He reached down and milked out a couple of streams of really thick yellow fluid. Then I felt it. It is not hot but seems kindof firm, about the size of a baseball. It does not seem to cause her pain. I have a CMT test kit in my goat barn that I test my goat with from time to time but have never tested a cow. The fluid is so thick I'm not even sure if I could get the tester fluid to mix with it. Any ideas? She is not bred, at least we don't think she is. I did not think that dairy animals not milking got mastitis?? :shrug: Thank you for any advice you can offer.
