I had a 350 lb. steer come down with the scours. It lived a week and then died. He lost a lot of weight and was very weak. I had had the calf for approx. 6 months. The day before he died, he nibbled at hay and we even turned him in our lawn to eat some of the tender grass. I feel that he may have gotten a piece of wire or metal in him. What do you think?
