In two experiments, the chemical characteristics of ensiled mixtures of corn stovers with either swine SE) or poultry (PE) excreta, with additions of molasses, urea and water to equilibrate moisture and nutrient content, were evaluated. In both experiments, treatments considered were (dry matter basis): T1, 60.0% corn stover, 2L5% molasses, 2.5% urea and 10% of either SE or PB; T2, 50.0% corn stover, 28.3% molasses, 1.7% urea and 20% of either SE or PB; and T3, 40.0% corn stover, 29.0% molasses, 1.0% urea and 30.0% of either SE or PE. After a 30 day fermentation period, the level of animal excreta, either SE or PB, did not affect (P>0.05) the total crude protein content of the silages. However, there were significant treatment differences (P
