The use of agroindustrial co-products is a viable alternative to producers to maintain animal production in times of lack and also to assist environment system, reusing disposal residue that can be discarted incorrectly. The aim was to estimate the kinetic parameters of ruminal degradation in vitro of three silages, one made with pineapple waste and two other are Cydonon cv. Jiggs silages with addition of agroindustrial coproducts: canola meal and seed cotton press cake. The work was conducted in the Laboratory of Parasitology of the Universidade Tecnológica Federal do Paraná, campus Dois Vizinhos. The pressure and volume readings were performed after 1, 2, 3, 6, 8, 10, 12, 16, 20, 24, 30, 36, 48, 72, 96, 120 and 144 hours of incubation. After four mathematic models were applied to predict ruminal kinetics in vitro and the M3 model was chosen for all silages. The silage with different levels of inclusion of canola meal and silage with pineapple waste can be used for the nutrition of ruminants due to the satisfactory behavior in the kinetics of ruminal degradation in vitro. Silage with levels of seed cotton press cake adversely affected ruminal degradation. |
