Abstract

The experiment was conducted at FMVZ-UNESP, Botucatu, SP, to study the effect of wilted and corn meal addition on ensiling and silage quality of alfalfa (Medicago sativa L.) The statistics design was full randomized in 2x3 factorial scheme with : two forage (fresh and wilted ) and three corn meal levels (0; 5 e 10%), totaling six treatments with four replications. The treatments were: T1-fresh forage; T2-fresh forage with 5% corn meal; T3- fresh forage with 10% corn meal; T4-wilted forage; T5-wilted forage with 5% corn meal and T6-wilted forage with 10% corn meal. The wilted used during ensiling was not enough to increase dry matter and water soluble carbohydrate in forages to have a good conservation of silage. However, the increased dry matter caused a decrease (p < 0,05) in buffer capacity. The wilted treatment with 10% corn meal corn improved the ensiled forage to induce significantly (p < 0,05) reduction in pH and ammonia nitrogen and it was the best treatment to avoid nitrogen degradation of the silage.
