Two metabolism trials evaluated the impact of dietary fiber source, level, and digestibility on daily production of bacterial crude protein. In the first trial evaluating corn silage, digestibility was unaffected while daily bacterial crude protein production estimated from urinary allantoin excretion tended to be higher as corn silage replaced corn. In the second trial digestibility was significantly lower for the finishing diets containing higher levels of dietary corn bran.
