Abstract

Two experiments were conducted to evaluate effects of three dietary inclusions (0%, 15%, and 30%, DM basis) of wet distillers grain plus solubles (WDGS) on feedlot performance and nutrient mass balance in open feedlots. Replacing corn with WDGS increased ADG response and HCW in both experiments. Feeding WDGS balanced for MP (15%) or in excess of requirements (30%) resulted in more OM in the manure but only more manure N in the winter experiment. Percentage N loss was not different among WDGS level but the amount of N lost was increased when WDGS were fed due to greater N excretion compared with cattle fed the control diet. Increasing dietary P with WDGS resulted in more phosphorus in the manure.
