Abstract

Two experiments evaluated supplemental degradable intake protein requirements when dried distillers grains were fed as an energy source in forage-based diets. Diets were formulated to be greater than 100 g/day deficient in degradable intake protein but with excess metabolizable protein. In both experiments, no response in performance was observed when urea was added to the diet. Sufficient urea was probably recycled to correct the degradable intake protein deficiency. These studies indicate adding urea to meet the degradable intake protein requirement is not necessary when dried distillers grains are fed as an energy source in forage-based diets.
