We are sampling Yesterday. He looks the part and his numbers are fantastic.
I agree that heredity is important when considering abnormal presentations--there may be an article in a Beef Magazine. Some breeders will not keep a calf for a bull if he was born backwards. When you researched breech births, did you find the thread (I'm not sure if it was on this message board or another one) that suggested that cows should not be running on extremely rough, unlevel pasture just ahead of calving, because that leads to more breech births? The only two breech births we have had, were both in a very hilly pasture where cows regularly climbed a steep creek bank.
