I would greatly appreciate any input anyone has on calves purchased from a sale barn. We just recently started raising holstein steers after we sold out out Dairy last October. We presently have 150 steers on our farm, which we raised from calves. We would probably have twice as many, but it seems our calf mortality rate is bad. We lose the majority of our calves to scours and Pneumonia. Any thoughts on how to manage this problem would be greatly appreciated.
