Elephant grass silage with addition of regional by-products

This study examines the effect of adding coffee husks (CH), cacao by-product (CBP) and passion fruit (PBP) (fresh-matter basis) in silage elephant grass cv. Napier on nutritional characteristics. The experiment was laid out a completely randomized design with 3 × 4 factorial arrangement represented by three additives (CH, CBP or PBP) four inclusion levels (0, 12, 24 36%). Four replicates were used per treatment. material ensiled experimental mini-silos that opened 60 days later for chemical analysis produced silages. dry matter content silages CH PBP included at greater than 25% adequate. showed highest crude protein best results vitro digestibility. In containing CH, neutral detergent fiber decreased linearly increasing husks. lowest pH. conclusion, up to 36% ensiling is recommended, as resulting has potential use ruminant feeding times forage scarcity.
