Just wondering if anyone has had the experience of a very docile bull throwing calves that are not very bright about nursing. I just started using a very docile bull and his first 5 calves gave me 4 bottle babies. They all want to suck the brisket and then when frustrated by that they lay down. I tried to get them to suck the teat and one calf would only suck the rubber nipple of the bottle. One calf that we got on her mother never nursed again on the teat and prefers the bottle. I wonder if the docility travels to the calf and they lose their survival instinct.
