I have a sick Angus steer calf, he was diagnosed last week with pneumonia, and the vet gave him antibiotic + vitamins/pain killer to increase his appetite. He continues to get worse, light cough/wheezing, won't eat now for several days. That was the 2nd time we took him to the vet, a month ago he had a cold/slight fever, he's always been a little depressed acting. He won't eat but his stomach is very round. I can't figure out why he has such a "grass belly". I'd say he's getting close to the end. Is there a common digestive disorder/block that also fits these symptoms? Any ideas? If it is pneumonia then how long does it take for the shots to help out? Its been 7 days.
