[QUOTE="J Hoy, post: 1734265, member: 16398"] My main necropsy experience was with wild grazing animals, especially white-tailed deer, our main study animal, so yes I have had lots of experience with twin births, just not in cattle. I did necropsy several beef calves that had externally observable birth defects including one that died of a set of twins. The sibling lived. All of the 7 beef calves I necropsied had an underbite and all but one had been diagnosed with Weak Calf Syndrome by a veterinarian. I am a biologist, not a vet. All the beef calves I necropsied also had those internal issues I stated above. According to the data on Weak Calf Syndrome, 3 of every 100 calves born in the U.S. each year die of WCS. That is around a million dead calves that can't be sold by the livestock owner, which is why I am trying to help you. That is close to a million cows that are fed for a year, with no return to the livestock owner - seems to me to be a huge, likely preventable waste. Since every calf that I examined that had WCS also had a fairly severe underbite, an underbite might indicate disrupted mineral uptake by the calf as a fetus, and that likely contributes to its mortality soon after birth.
