Abstract

For three years, cows and first-calf heifers were supplemented two levels of RUP prior to breeding to determine the effect of RUP on reproductive efficiency and performance. Cows resumed estrous after being supplemented 30 days with distillers grains, but pregnancy rate was not different. First-calf heifer performance and reproductive efficiency was similar regardless of protein supplement offered. Protein supplements offered in this study did not impact cow BW, milk production, or progeny performance. More cows supplemented with distillers grains prior to the breeding season resumedluteal activity prior to breeding; however, pregnancy rates were similar.
