Ethanol producers remove lipid from distillers grains (DG) for applications such as biodiesel production. The effects of the lipid removal on ruminal protein degradability and total-tract CP digestibility of DG are not known. Five ruminally and duodenally cannulated Angus-cross steers (BW = 434 ± 15 kg) were used to incubate in situ bags for determination of protein digestibility of low-lipid (5.54%) DG, medium-lipid (8.40%) DG, high-lipid (12.46%) DG, and cottonseed meal. Ingredients were weighed into individual in situ bags and incubated in the ventral sac of the rumen for 16 h. After ruminal incubation and simulated abomasal digestion, bags were …

A 2-yr study evaluated effects of feeding dried distillers grains (DDG) to yearlings grazing native range at greaterthan- recommended stocking rates on BW gain, grazed forage quality, and forage disappearance. Thirty-six paddocks were assigned randomly to 1 of 3 treatments: 1) control, stocked at a moderate stocking rate (1.48 animal unit months/ha in yr 1, 1.06 animal unit months/ha in yr 2) with no DDG; 2) double stocked, in which stocking rate was exactly twice the control with no DDG; and 3) double stocked with 2.27 kg/d (DM) of DDG per animal. Six paddocks per treatment replication were grazed in …
