We had a breach calf 2 weeks ago that was around 80 pounds. He was doing well at first until we moved him and his Mom to our new pasture when he was a week old. He developed the scours and was very weak. We took him to the vet to get tube fed and treatment with Moticil (Doc indicated there could be pneumonia because of breach birth) and vitamins. We tube fed him 3 times and then he got to feeling better and nursed on his own. Buddy was doing really well for about three days and we thought we were over the hump (he was running and seemed perfect) and now he's back to being weak again and he has a really runny nose. He doesn't have an appetite again and he also has a very red and peeley nose. We tubed him last night and checked him this morning - nose is more runny now but he got up. He doesn't look like he's nursed overnight. When we tubed him last night, he threw up so he's got a little milk in him, but not much at all. Any suggestions on what to do?
