> Early prevention is a key issue here. The bos scour guard for mom is helpful, and at first sign of a temp or runny nose or scours, immediatly administer shots, or scour pills or what ever your thing may be. Keeping calves out of the wet area is very helpful too if possible. Its a tough situation, but rigourous prevention can help some. The previous owners of our place lost 11 calves out of 80 the year before we bought the ranch. They showed us where they calved. Once scours is in the ground, it stays there for awhile. We moved our calving area across the road the first year, and didnt lose one calf to scours. So possibly the ground your calving on is part of the culprit. Just a suggestion. Good Luck!
