Abstract

A feedlot experiment evaluated the effect of increasing fiber in distillers grains diets on ADG, F:G, and nutrient mass balance. The treatments consisted of 1) 30% modified distillers grains plus solubles, no roughage (MDGS), and 2) 30% modified distillers grains plus solubles, 30% wet corn gluten feed, and 15% corn silage (MDGS+fiber). The remainder of each diet consisted of a 1:1 ratio of high moisture corn and dry rolled corn and 5% supplement. Feeding MDGS+fiber increased (P < 80.02) ADG, DMI, and HCW; however, it did not improve F:G compared to MDGS. By increasing the fiber content of the diet, more organic matter (OM) and N remained in the manure. Percentage N loss was not different between dietary treatments; however, amount of N lost increased with MDGS + fiber due to the greater N intake and excretion.
