Three experiments have been designed to determine the feeding value of soybeans and roasted soybeans in growing and finishing cattle diets. In year 1, a finishing experiment will be performed to compare the inclusion of soybeans, roasted soybeans, and soybean meal with DDGS, either for the entire length or for the second half of the feeding period. In year 2, a growing trial will be performed to quantify the RUP content and value of roasted soybeans in growing calf diets. In both experiments cattle performance (weight gain and feed efficiency) will be used to compare the protein value of whole soybeans, roasted whole soybeans, soybean meal and distillers grains plus solubles. In year 3, a finishing experiment will be performed to compare the different digestibility values of the protein factions of soybeans, roasted soybeans, and soybean meal with DDGS in isonitrogenous and isocaloric diets.
