Title: Rumen fermentation characteristics, nitrogen balance and growth in lambs fed methane digester effluent

Abstract

A laboratory silo trial, two lamb metabolism trials and a lamb growth trial were conducted to compare the nitrogen (N) value of swine methane digester effluent (MDE) to that of urea. Using laboratory silos (four/treatment), fermentation characteristics were measured for silages containing cracked corn, ground wheat straw and MDE added at levels of 0, 4, 8 or 12% of silage dry matter (DM). Lactic acid concentration increased linearly with up to 8% MDE addition, but then decreased with 12% MDE. Butyric acid was highest with 12% MDE, indicating an undesirable fermentation. In a metabolism study, DM, organic matter and N digestibilities and N balance were similar between urea and MDE, but DM digestibility was lower for ensiled diets (52%) than diets fed fresh daily (59.4%). Mean ruminal volatile fatty acid, ruminal ammonia-N and plasma urea-N concentrations were similar between urea- and MDE-fed lambs. Plasma urea-N was higher and ruminal isovaleric acid lower in animals fed ensiled than fresh diets. In the second metabolism trial, digestibility of N was lowest for MDE and highest for soybean meal, but N balance was similar among all diets.
