          Abstract

          ABSTRACT. Conservation of summer forage excess represents a management strategy to meet animals' needs for dry matter in the shortage period, but has been poorly studied. Silage can be used for this purpose. This study analyzed the production of palisade grass silage from pasture subjected to different grazing intensities with and without additive, determining losses by gases and effluents and chemical composition of silage. The experiment was a 4 x 3 factorial completely randomized design, with four replications. The factors were: 1st - herbage allowance of 5% (5 kg dry matter 100 kg-1 of animal weight day-1), 10, 15 and 20%. The pasture was managed under rotational stocking with 35-day grazing cycles (7 days of occupation and 28 days of rest) and 2nd - additives: a) control; b) citrus pulp pellets; c) biological inoculant for grass silage. The forage of palisade grass harvested from pastures subjected to low-intensity grazing showed quantitative and qualitative characteristics for ensiling. However, high humidity and low fermentable carbohydrate require the use of additive, favor the fermentation process and increase the nutritional quality of silage.

          RESUMO. Técnicas de conservação do excedente de forragem do verão constituem estratégia de manejo do pasto para suprir as necessidades dos animais em massa seca no período de escassez, porém pouco pesquisadas. A silagem pode ser utilizada para esse fim. Estudou-se a produção de silagem de capim Marandu, proveniente de pastos submetidos às intensidades de pastejo, com e sem aditivo, determinando-se as perdas por gases e efluentes e a composição química e bromatológica da silagem. O delineamento experimental foi inteiramente ao acaso e o experimento em fatorial 4x3, com quatro repetições. Os fatores foram: 1º - ofertas de forragem de 5% (5 kg de massa seca 100 kg-1 de peso animal dia-1), 10, 15 e 20%. A pastagem foi manejada em lotação rotativa, com ciclos de pastejo de 35 dias (7 dias de ocupação e 28 dias de descanso) e 2º - aditivos: a) controle; b) polpa cítrica peletizada; c) inoculantebiológico para silagens de capim. Verificou-se que a forragem de capim-marandu colhida de pastos submetidos à baixa intensidade de pastejo apresentou características quantitativas e qualitativas para ensilagem. Porém, a alta umidade e o baixo teor de carboidratos fermentescíveis tornam a utilização de aditivo necessária e favorável ao processo fermentativo e a qualidade nutricional da silagem.

            A meta-analysis of the effects of Lactobacillus buchneri on the fermentation and aerobic stability of corn and grass and small-grain silages.

            The results of adding Lactobacillus buchneri to silages from 43 experiments in 23 sources reporting standard errors were summarized using meta-analysis. The effects of inoculation were summarized by type of crop (corn or grass and small grains) and the treatments were classified into the following categories: 1) untreated silage with nothing applied (LB0), 2) silage treated with L. buchneri at 100,000 cfu/g (LB2). In both types of crops, inoculation with L. buchneri decreased concentrations of lactic acid, and this response was dose-dependent in corn but not in grass and small-grain silages. Treatment with L. buchneri markedly increased the concentrations of acetic acid in both crops in a dose-dependent manner. The numbers of yeasts were lower in silages treated with LB1 and further decreased in silages treated with LB2 compared with untreated silages. Untreated corn silage spoiled after 25 h of exposure to air but corn silage treated with LB1 did not spoil until 35 h, and this stability was further enhanced to 503 h with LB2. In grass and small-grain silages, yeasts were nearly undetectable; however, inoculation improved aerobic stability in a dose-dependent manner (206, 226, and 245 h for LB0, LB1, and LB2, respectively). The recovery of DM after ensiling was lower for LB2 (94.5%) when compared with LB0 (95.5%) in corn silage and was lower for both LB1 (94.8%) and LB2 (95.3%) when compared with LB0 (96.6%) in grass and small-grain silages.
