To evaluate the effect of rates of distillers’ grain supplementation on substitution for pasture,
In the second stocker study at the McNay Farm, unsupplemented heifers were compared to those supplemented with 1.5 percent of their bodyweight of Dakota Bran. Dakota Bran is a co-product produced by a fractionation process where the corn germ is separated, and oil is partially removed prior to fermentation. The corn bran is also removed at that time and the remaining endosperm fraction is used for ethanol fermentation. Dakota Bran is a combination of corn bran and condensed distillers’ soluble. This feedstuff can be more easily pelleted, making it an attractive grazing supplement from a handling perspective. During the supplementation period, cattle fed the Dakota Bran gained 1.48 pounds per day compared with 0.79 pounds per day for the control cattle. Calculations based off sward height measurements indicated that the supplemented cattle consumed 26.8 percent less pasture. Gain per acre increased by approximately 100 pounds and at a similar cost, based on the costs at the time of the study.
