In September I bought a dairy bull calf. He was about 10 weeks old I think. Supposedly weaned, but seemed to want to suck on anything. I started him on pasture, grass hay and calf starter. He seemed very healthy. No scours or anything. Then we banded him in October and his sack never fell off. It dried up though. Then after about a month he started swelling up around the band and I could tell it really hurt him. He walked around minimally and always hunched up his back like it hurt. A rancher I know told me not to worry about it, that it was probably a little infected, but they all got that way. Then it got REALLY cold in November. Maybe below zero, and stayed there for a few days. I don't think he was even going to the trough to drink. I found him laying in the barn with one of his entire back legs frozen solid. I put him down. I'd really like to raise some more calves but, now I'm scared that I will kill them all. That's a lot of money down the toilet. Should I have given him an antibiotic? Was he just too small to be going into a harsh North Dakota winter?? Please help so that I can do this better next time. I think this year I will make sure that any calves I have are bigger going into winter. I also had him in the same pen as my big heifer and four goats. Maybe I should have had him in a pen by himself? This has left a sour taste in my mouth. Thanks for the help.
