The objective of this study was to evaluate and compare in situ dry matter (DM), crude protein (CP) neutral detergent fiber (NDF) degradabilities three pearl millet genotypes silages (BRS-1501, NPM-1 e CMS-3), incubated at 6, 12, 24, 48 96 hours sheep. experimental design a randomized block split plot arrangement, the means compared by SNK test 5% significance level. Values effective degradability 2.0%/h, 5.0%/h 8.0%/h passage rates were: 48.5%, 39.6% 35.8% for BRS-1501 silage, 46.3%, 38.1% 35.0% silage 47.8%, 40.2% 36.9% CMS-3 respectively. highest degradation rate (2.08% / h), solubility (74.4%) CP were observed CMS-3. potential (A) NDF equal potentially degradable fraction (B1) all silages, whose values 52.3% (BRS-1501), 57.6% (NPM-1) 46.6% (CMS-3). presented high showed better quality fraction. Low silages. According findings work, nutritional value than due their degradabilities.KEYWORDS: Nutritive value, roughage, ruminants, supplementation.
