Conteúdo: 	Abstract: Two experiments were conducted to evaluate the nutritional quality of cattle manure silage for lambs. In experiment 1, qualitative characteristics, pH and lactic acid were determined in ensiled corn stover (35%) with four combinations (treatments, T) of fresh cattle manure:cane molasses-urea mixture (T1, 55:10; T2, 45:20; T3, 35:30; T4, 25:40). Lactate concentration (% of DM) was greater for the first two combinations (T1, 4.6a; T2, 4.1a; T3, 3.4b; T4, 2.7c; different superscripts indicate difference at P < 0.05). Experiment 2 was conducted to evaluate apparent digestibility and nitrogen balance of 20 lambs (29.0 ± 5.5 kg initial BW) fed silage with 50% cattle manure, 8% cane molasses, 12% water and 30% corn stover. For this silage, molasses and urea ratio was 20:1. Different silage levels (T1, 0%; T2, 16.4%; T3, 32.7%; T4, 49.1%; T5, 65.5%; DM basis) were used in a completely randomized design with four lambs per treatment. Diets included sorghum grain (18.4%) and soybean meal (16.50, 13.20, 9.90, 6.60 and 3.30%). In T5 a lower (P < 0.05) apparent digestibility was found for OM (T1, 57.6%a; T2, 59.1%a; T3, 55.3%a; T4, 53.4%a; T5, 51.7%b); but ADF, hemicellulose and energy digestibility did not change (P > 0.05). Nitrogen balance (g day?1) was lower (P < 0.05) for T5 (T1, 6.4a; T2, 5.5a; T3, 6.8a; T4, 5.8a; T5, ?0.1b). According to these results, cattle manure can be ensiled when molasses and urea proportions are adequate (20:1), and DM digestibility is not affected negatively if cattle manure silage is included up to 49% (DM basis) in lambs diets.
