Summary: | ABSTRACT The nutritional composition of silages from the millet cultivars BRS 1501, ADR 500 and ADR 8010 was evaluated with the inclusion of soy hulls at 0, 3, 6 and 10%. The experimental design was completely randomized in a 3 x 4 factorial scheme with 3 replications. The dry matter content of the silages was affected by the inclusion of the soy hulls, ranging from 16.20% (ADR 8010) to 23.27% (BRS 1501) for the inclusion of 0 and 10% respectively. The levels of crude protein ranged from 9.46 to 10.79%, with significant differences between varieties being seen with the inclusion of 6% and 10% soy hulls. Inclusion of the hulls reduced the mineral matter content of the silages, with a change of 8.62% in the control treatment, up to an average of 6.38% at the level of 10%. The neutral (NDF) and acid (ADF) detergent fiber content did not differ with treatment. The hemicellulose content differed with the level of soy hulls, and ranged from 22.65 to 26.18%. The cellulose content varied from 24.90% (ADR 500), with the inclusion of 6% soy hulls, to 29.80% (ADR 8010) with the inclusion of 10% hulls. The lignin content showed significant differences for the level of hull inclusion, ranging from 1.37% (ADR 8010) with the inclusion of 10% hulls, to 3.71% (BRS 1501), found in the control treatment. The soy hulls increased the dry matter content of silages from the cultivars under evaluation.
