PERFIL FERMENTATIVO DA SILAGEM DE MILHO, LEGUMINOSAS E MISTAS

Abstract

The partial replacement of the corn crop by tropical legumes for silage production has aroused interest, 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 food in a more sustainable way. In this context, the objective was to evaluate the fermentative profile of corn silage with 30% 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 fermentative and chemical characteristics of the silages. The results demonstrate that exclusive leguminous silage presents fermentation losses that compromise the quality of the silage. The Campo Grande and Bela styles are more recommended for corn ensilage. In this way, mixed maize and leguminous silages are an alternative to promote greater sustainability, in addition to reducing the fermentative losses of exclusive leguminous silages.
