Title: Nutritive value of methane fermentation residue in diets fed to feedlot steers

Abstract

Nutritive value of the methane fermentation residue (MFR) from the effluent of a large scale thermophilic methane generator was determined in diets fed to feedlot steers. The MFR contained 22.2% dry matter and 21.9% crude protein (dry basis). Two diets containing 10.6% (dry basis) MFR were formulated using the Urea Fermentation Potential (UFP) system such that in one diet N was in excess (-1.6 UFP) while in the other diet energy was in excess (+2.6 UFP). These two diets were compared in a California Net Energy trial with a feedlot diet (-.3 UFP) containing the same ingredients except the MFR. Six steers were fed in a replicated 3(2) Latin square metabolism trial and 70 steers were fed in a 118-d comparative-slaughter, feedlot trial. Digestibilities of dry matter, organic matter, crude protein, acid detergent fiber, ash, total digestible nutrients (TDN) and metabolizable energy were depressed (all P less than .05) in the MFR-containing diets. Steers fed the MFR-containing diets had lower (P less than .05) rates of gain and increased (P less than .05) feed requirements per unit gain. Net energies for maintenance and gain were slightly lower for the MFR-containing diets than the control diet. Crude protein digestibility for themore » MFR calculated by difference, for the -UFP and the +UFP diets were 37.8 and 50.7%, while corresponding values for TDN were 28.8 and 12.8%, respectively. Concentrations of potentially toxic elements in kidney, liver and muscle as well as flavor and tenderness of steaks were not affected by feeding MFR.« less
