Your bull will be half of every calf you produce. No matter how good your cows are, your bull can bring that crashing down. It would depend a great deal on what bull he is out of and how productive his momma is. Don’t always get hung up on how good he looks, especially before about 2 years old. It’s more about the genetics than anything else, and those predictors are readily available these days. I’m not scared to use a bull that I raise, if I can be sure that his genetics are what I want to move forward with, not because he looks good or not that good. My worst looking bull produces my best calves currently, but he’s backed by genetics.
