I have a Brangus bull, approximately three and a half years old. Over the last month or so he has lost a good bit of weight. For about the last 3 months he has been breeding a herd of 15 cows. He is alert, mobile, and when the last cow came in heat (this past week) he was definately interested. There's plenty of grass, he grazes and will eat feed/ corn when offered. he was wormed with pour on about 2 months ago. I am concerned about the weight loss. Any ideas appreciated.
