ATM OH said:Have had this happen with calves out of a Simmental herd bull we used in the early 90's. Also had it happen from an AI Simmental bull called Red Blaze in the mid 90's. Always thought it was some sort of Simmental defect?
Dyer Show cattle said:First off does the calf have a high BW like 90+ lbs. If so I have seen this in about every breed out there. High BW calves joints are sometimes underdeveloped and they just dont have the strength to stand on their hooves. Also with bigger BW calves there is a lot more strain on them during birth making them weak for the first few days. So if it was a long labor and a big calf I would not worry about it, bottle feed the calf or stand him up to nurse and within a couple days they usually come right around. Now if it was a small calf I would look on the genetic side a little more.
