We have a 2 1/2 week old calf, Gerald. The first few days he started having the yellowish/tan diarrhea along with pneumonia. We got the pneumonia cleared and hes back to eating great, drinking plenty of water and active. The diarrhea hasn’t stopped. We’ve been giving him the scours tablets but nothing has helped. What else can I do? I did add electrolytes to his water also. We’ve been keeping everything clean including him.
