We bought a 2 and 1/2 month old bull calf Saturday. I am going to band him and give tetanus shots. What about worming? What should I use and when? He isn't eating grass or hay yet and is on a high protein feed that was recommended by the feed store. We are offering free choice good hay and he is starting to pick at it. He will be on pasture and hay, plus grain, with a small herd of goats. He weighs about 175 to 200 pounds. Half Holstein and half charlais. I have used the banding method on the goats and it has worked well in the past with no infections.
