Hi I live in Wausau WI and it was cold here for a few weeks. I think our steer has gotten lice. He is really on edge when I look through the hair and there are a lot if little brown things. Anyway will lice cause weight lose? This would be my lice issue so don't know much about it. Also I would like to start getting him wider do I crank up the energy? Thanks for your advice!!!!
