Ok its been awhile since I had a case off pneumonia. But I do now. A fall calf I bought came down with it 3 days after I bought it. Probably had it when it was young. I had the vet treat it yesterday. But to no avail seems to be worse today. Just curious what the usual course off treatment is. Does it get worse before it gets better. The calf is alert just the pneumonia. This steer weighs about 550 lbs. What would you do next? A quick response would be nice. I caught this pretty early but am just trying to learn a bit here. THANKS FOR ANY HELP.
