I am probably going to get blasted for this, but, here goes. Why do we keep spreading PHA and TH by using carrier bulls and females? I am amazed every spring when I look through the new sire catalogs and see page after page of carrier genetics being promoted. I am a very small operation but I simply won't use carrier bulls and my cows are genetic defect free. Am I the norm or the exception? I recently read an ad in a popular sire catalog which said, and I paraphrase, "he's a defect free bull that looks like a carrier." I read it last year in the same catalog. With all the worries the calving season brings, do we really need to kick ourselves by using carrier genetics?
