VALOR NUTRITIVO DA SILAGEM DE MILHO, LEGUMINOSAS E MISTAS

Abstract

The partial replacement of the corn crop by tropical legumes for silage production has aroused interest in producers, as it brings benefits such as balancing the nutritional value, improving the qualitative characteristics in the dry matter, in addition to the flexibility of use, constituting an important alternative for the production of food in a more sustainable way. In this context, the objective was to evaluate the nutritional value of corn silage with 30% of tropical legumes. The experimental design used was completely randomized, with three replications. The treatments consisted of silage: corn; Campo Grande stylists; Bela stylists; Guandu beans; corn + 30% Campo Grande stylosanthes; corn + 30% Bela stylus and corn + 30% Guandu beans, totaling 21 experimental silos. After 50 days of fermentation, the silos were opened to evaluate the bromatological characteristics of the silages. The results showed that the addition of 30% of legumes to corn silage improves the crude protein content of the silage. Campo Grande and Bela styles are more recommended for ensilage with corn, as they have a lower fibrous fraction. Mixed maize and leguminous silages are an alternative to improve the crude protein content of maize-only silage and promote greater sustainability.
