Reading other sites, I've heard comments that EPD's (expected progeny difference) numbers can be fudged. And in the thread on dairy bull disposition, sounded like AI companies were reluctant to consider temperament, even though it could ruin a herd. So, do you trust numbers on bulls? Is there any outside verification of those numbers? Where do they get the data? From breeders own herds, or from people they've sold the semen to? Just wondering if AI companies always have the end producers interests in mind.
