Abstract

Summary with Implications

A finishing trial was conducted to evaluate the effects of varying dietary inclusion of modified distillers grains plus solubles compared to a constant inclusion throughout the entire feeding period on finishing cattle performance. Treatments were arranged as a 2 × 2 + 1 factorial with two inclusions of modified distillers grains plus solubles (10% and 25%) that were constant or varying in dietary inclusion, and a corn control (0% modified distillers grains plus solubles). Increasing the inclusion of distillers grains from 0 to 25% increased both DMI and ADG when fed at a constant inclusion of 10 or 25%. When inclusion varied around 10 (0 to 20%) or 25% (15 to 35%) inclusion, only ADG tended to increase and to a lesser degree. Varying the inclusion of distillers grains in the diet due to supply disruptions or incorrect loading may lessen the improvements in animal performance compared to including distillers at a constant rate in the diet every day.
