FRACIONAMENTO DE PROTEÍNA E CARBOIDRATO DA SILAGEM DE MILHO EXCLUSIVA E COM ADIÇÃO DE CAPIM-TAMANI

Abstract

Mixed silage production is a promising alternative for ruminants. However, changes in the chemical composition of silage may occur due to treat two separate forages. Thus, the objective was to evaluate the fractionation of proteins and carbohydrates from exclusive corn silage and added with tamani grass. THE The experiment was conducted at the Goiano Federal Institute, Rio Verde Campus, Goiás, in A completely randomized experimental design with four replications. The treatments consisted of silage: exclusive corn; corn with 10% tamani grass; corn with 20% tamani grass; maize with 30% tamani grass and maize with 40% tamani grass, totaling 20 experimental silos. For ensiling, the corn was harvested with 320 g kg-1 MS and tamani grass in the 30-day development cycle. After 50 days of silage, the silos protein and carbohydrate fractionation were opened for analysis. The results showed that adding 40% of tamani grass to maize silage increased A and B1 protein and A + B1 carbohydrate fraction, being an interesting alternative for improve the quality of unique corn silage.
