Fermentation characteristics and nutritive value of sweet sorghum silage with Paiaguas palisadegrass and Ipypora grass

Ensiling sorghum with tropical forages has been shown to be a promising alternative for ruminant feed production, as this approach improves the quality of silage. In context, goal study was evaluate fermentation characteristics and nutritive value sweet silage made different levels Paiaguas palisadegrass Ipypora grass. The experiment conducted in completely randomized 2 x 6 factorial design four replications. Two (Paiaguas grass) were added at six (0, 20, 40, 60, 80 100%), total 48 experimental silos. After 50 days fermentation, silos opened, profile chemical composition analysed. results showed that addition grass increased pH, buffering capacity NH3-NT reduced its dry matter content but did not affect characteristics, which remained within an appropriate range. increasing crude protein vitro digestibility (IVDMD) decreased fibre fraction (neutral detergent fibre, acid lignin) ether extract contents. Adding material above 40% is recommended. Among forage crops, resulted higher IVDMD. Mixed silages can effective improve
