Got a 23 day old bottle calf that was doing pretty good until the night before last. He was a twin and did not get Colustrum from momma. I had to tube him with store-bought colustrum about 18 hours after he was born, which I know probably didn't do any good. The first week it was 50/50 and then his energy started coming to him and he would jump and buck when he saw me coming with the bottle. He has been scouring a little for about 2 weeks and I can't seem to get rid of them. His energy level was great until the night before last. He wouldn't take the bottle at all and was lethargic. He has not shown any signs of dehydration. I got him to take 2 pints of milk yesterday morning but couldn't get him to take anything last night. This morning he was trembling and feverish although he did take 3 pints of milk. Gave him a shot of Baytril because thats all I had on hand besides LA 300. Called 3 vets and all are "too busy" to see him. One of them told me it was probably navel infection setting in and to start him on 8cc of Penicillin a day for a week and then bring him to his clinic and he would remove the infection. I don't feel an abscess anywhere around the navel and I don't think he has a hernia either. He was better tonight and took all his milk that I gave him and his energy level seemed a lot better. I'm not 100% convinced it's navel infection but I'm not sure what else it could be. Any ideas? Thanks for ya'lls help.
