The objective of this study was to evaluate and to comparein situ dry matter (DM), crude protein (CP) and neutral detergentfiber (NDF) degradabilities of three pearl millet genotypes silages(BRS-1501, NPM-1 e CMS-3), incubated at 6, 12, 24, 48 and 96hours in sheep. The experimental design was a randomized blockin split plot arrangement, and the means compared by SNK test at5% significance level. Values of effective degradability at 2.0%/h,5.0%/h and 8.0%/h passage rates were: 48.5%, 39.6% and 35.8%for BRS-1501 silage, 46.3%, 38.1% and 35.0% for NPM-1 silageand 47.8%, 40.2% and 36.9% for CMS-3 silage, respectively. Thehighest degradation rate (2.08% / h), solubility (74.4%) and effectivedegradability of CP were observed for CMS-3. The potentialdegradability (A) of NDF was equal to the potentially degradablefraction (B1) in all silages, whose values were 52.3% (BRS-1501),57.6% (NPM-1) and 46.6% (CMS-3). CP fraction of pearl milletsilages presented high solubility and CMS-3 silage showed betterquality of this fraction. Low NDF degradabilities were observedfor all silages. According to the findings of this work, the BRS-1501 and CMS-3 silages presented better nutritional value than theNPM-1 due to their highest effective degradabilities. |
