I had my entire dairy herd tested a couple months ago b/c a ff freshened w/ a hard udder, and another breeder said it 'felt' like CAE mastitis.
10 negatives, 3 positives, ALL 3 positives are asymptomatic / act / seem fine.
One of the positives, Doodle...was out of a CAE neg. tested dam, her 2 sisters that are here tested negative, AND her daughter tested negative....AND ALL were caught at birth / raised on heat treated colostrum and pasteurized milk.
The other 2 positives weren't born here....
And the one I was suspicious about...tested negative.
But I'm just dumbfounded how Doodle got it, IF it is a true positive....she'll be retested shortly.
And she's NEVER had mastitis, she has the prettiest BIG productive udder on the place.
