Supplementing Beef Cows Grazing Cornstalk Residue with a Distillers Based Cube

A 4-year study is being conducted to determine the effect of excess undegrad¬able intake protein supplementation using a cube that is 2/3 dried distillers grains (DDG) to beef cows in late gesta¬tion on cow and calf performance and the performance of heifer calves whose dams were supplemented with protein. Feeding a supplement containing DDG did not influence calf birth and wean¬ing weights, cow body weight prior to calving, and calving interval. Cow body condition score and percentage of cows cyclic prior to breeding increased for supplemented cows
