Resumo: | he aim of this study was to evaluate fermentation and chemical characteristics and the in situ degradability of sorghum silages enriched with dried Leucaena. The experiment was conducted as completely randomized design with four treatments (0 - control silage, silage without leucaena; 10.0, 20.0, or 30.0% inclusion of Leucaena) and five replicates, totaling 20 experimental units. The inclusion levels of leucaena influenced (P 0.05), with all silages having values above 90%. Gas loss decreased (P < 0.05) as the level of leucine increased in sorghum silage. A linear increase was observed for dry matter (P ? 0.0001) and crude protein (P = 0.0008) contents in response to Leucaena inclusion. There was a linear (P < 0.05) linear effect on neutral detergent fiber, hemicellulose and acid detergent fiber. As leucaena inclusion levels increased, for each 1% inclusion a reduction of 0.179 was observed; 0.059 and 0.119% for the values of neutral detergent fiber, hemicellulose and acid detergent fiber respectively. The inclusion of leucaena influenced (P < 0.05) the increase of silage lignin levels, probably due to the higher lignin content of the legume. The soluble fraction (a) of the silages increased along with the Leucaena inclusion levels, with highest values observed at the inclusion of 20 and 30% of the legume, respectively. Potential degradation (A) increased linearly with the levels of Leucaena added to the silage; the highest value for this variable was observed at 30% inclusion. Effective degradability (ED) increased up to the inclusion level of 20% (46.77%). Degradation rate (c) decreased markedly with the use of 30% Leucaena. The use of the forage part of Leucaena dried for three hours leads to reduced gas production, increased dry matter and crude protein contents, and decreased fiber contents. The degradability of dry matter increases up to the inclusion level of 20%. |

Este trabalho teve como objetivo avaliar a produção de biomassa, a composição física da planta, a bromatologia e os teores de matéria seca da planta e componentes estruturais do milho para forragem. O delineamento experimental foi em blocos inteiramente casualisados, em esquema fatorial 5x5, com cinco densidades de plantio (80, 160, 240, 320 e 400 mil plantas ha-1), colhidas em 5 épocas (40, 50, 60, 70 e 80 dias após o plantio). O fator época de colheita apresentou diferença estatística em todos os parâmetros, e o fator densidades de plantio só apresentou diferença estatística em participação de folhas e produção de biomassa seca. Não houve interação em nenhum dos parâmetros avaliados. O milho forragem, cortado em período vegetativo, pode ser um grande aliado do produtor rural, pois apresenta alto potencial de produção de alimento com alto valor nutritivo em período reduzido de tempo, e em quantidade significativas com produção de até 14.720 kg há-1 de biomassa seca alcançada aos 80 dias de ciclo com 320 mil ha-1, liberando o solo para produção de outra cultura.UEL2019-08-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3314010.5433/1679-0359.2019v40n5Supl1p2397Semina: Ciências Agrárias; Vol. 40 No. 5Supl1 (2019); 2397-2406Semina: Ciências Agrárias; v. 40 n. 5Supl1 (2019); 2397-24061679-03591676-546Xreponame:Semina.
