RECUPERAÇÃO DE MATÉRIA SECA EM SILAGEM DE CAPIAÇU(Cenchrus purpureus) COM DIFERENTES NÍVEIS DE FARELO DE SOJA

Abstract

The BRS Capiaçu cultivar, developed by EMBRAPA, stands out for its forage production, good nutritional value, and characteristics favorable to silage. However, its high moisture content can cause significant losses during the fermentation process, such as the release of effluents and gases. This study aimed to evaluate the dry matter (DM) recovery in Capiaçu silages with different levels of soybean meal inclusion (0%, 7%, 14%, and 21%), with and without the use of bacterial inoculants. A completely randomized design was used, in a 2 x 4 factorial scheme (with and without inoculant and four levels of soybean meal). The experiment was conducted at the Instituto Federal Goiano – Campus Morrinhos, using 20 L experimental silos. The analyses showed that the addition of soybean meal contributed significantly to the reduction of total losses, decrease in effluents, and increase in dry matter recovery, regardless of the use of inoculant. The isolated use of inoculants did not promote consistent improvements in dry matter recovery, indicating that increasing the DM content by adding energy sources such as soybean meal is more effective in improving silage quality.
