Composição química e digestibilidade em ovinos da grama estrela ensilada com diferentes aditivos

Objetivou-se com o estudo avaliar a composicao quimica e a digestibilidade aparente em ovinos da grama estrela ensilada com diferentes aditivos. Os aditivos empregados foram o enzimo-bacteriano (em duas concentracoes) e a ureia (10 kg/tonelada), totalizando quatro tratamentos. Para o experimento de digestibilidade, foram utilizados quatro ovinos machos castrados distribuidos em delineamento quadrado latino (4x4). Em relacao a composicao quimica, as variaveis MS, PB, EE, FDA e LIG apresentaram diferenca (P<0,05) entre os valores obtidos, porem a FDN nao mostrou diferenca entre tratamentos. Quanto a capacidade tampao e ao pH os menores valores foram obtidos com os tratamentos com aplicacao de inoculante. Nao houve efeito de tratamento (inoculante ou aplicacao de ureia) sobre a digestibilidade da MS, PB e FDN.

Determinação da massa específica de silagens de milho por método indireto

An alternative method to estimate the specific mass (SM) of silage were evaluated in two studies with corn silages in trench silos. The values of penetrometer resistance were correlated with the SM values obtained with the use of sampling by a metal cylinder and the SM of the silage was estimated by means of regression. Since there was a high positive relationship of penetration resistance of the metallic cone and SM estimated with SM observed, the penetrometer can be used as indirect method for determining the SM of corn silage.

Performance and carcass characteristics of lambs fed high moisture corn silage with soybean seeds, sunflower seeds or urea

Silage of high moisture corn using additives to increase nutritional value, especially in relation to crude protein and energy could give to farmers an alternative to commercial concentrates (Jobim et al., 2009). This research was conducted to evaluate the effect of diets with high moisture corn that received inclusion of soybean grain, sunflower grain or urea as additive during ensiling over lambs performance.
