Silagem de capim mombaça adicionada com inoculante microbiano e enzima xilanase: perdas e estabilidade aerobica

Abstract

The silage is an important alternative for feeding ruminants in the period of food shortages. In order to reduce losses and improve qualitative characteristics, are added during the process of silage additives. The aim of this study was to evaluate the osses and aerobic stability of silage fermentative of Mombasa grass inoculated with Lactobacillus plantarum and Pediococcus acidilactici and the use of the enzyme Xylanase. The experiment was conducted on the premises of the Department of animal science, Faculty os agricultural sciences of the Universidade Federal da Grande Dourados, from May to September 2013. The experimental design used was the completely randomized design, composed of 60 mini-silos with three levels and Inoculants and two levels of enzyme products. Before the silage, forage was sampled for further analysis and qualitative characteristics. After the compression of the forage, the silos were sealed, weighed and stored. To 60 days of fermentation. Silage temperatures in the period after opening were taken every 8 hours during 5 days by means of an infrared thermometer. The Inoculants increased the protein content of silage. The Inoculants decreased gas and effluent losses. Enzyme treatment showed minor losses, total effluent gas than the control. Inoculants not have decreased the pH compared to control, in silage used enzymes was observed pH less than the control. The Inoculants not have decreased the temperature stability of the silos. The use of Inoculants and enzymes not improve aerobic stability and nutritional composition, decreased total losses and increased the number of lactic acid bacteria in Mombasa grass silage.
