Efecto de la suplementacion con ensilaje de residuos de una planta procesadora de tilapia (Oreochromis niloticus) sobre el consumo voluntario y la digestibilidad de nutrientes de heno de gramineas y leguminosas tropicales

摘要

One of the biggest problems facing the fishery industry is disposal of the organic wastes that result from fish processing (discarded fish and filleting residues). Alternatives for disposal of this material should be evaluated. Silage preparation represents a possibility to enable use of those organic residues as a supplement in diets for domestic animals. Two experiments were conducted to determine the effect of supplementation with tilapia fish silage (FS) prepared in laboratory scale silos with addition of cane molasses, on intake and digestibility of tropical grass hay (Digitaria eriantha , 80%, and Panicum maximum, 20%), and rhizome perennial peanut hay (RPPH) (Arachis glabrata). In Experiment 1, grass hay was the basal diet and treatments were (Control; T1 grass hay) and grass hay supplemented daily with FS at 0.45% (T2) and 0.90% (T3) of the animal body weight (BW). In Experiment 2, the basal diet was RPPH and treatments were (Control; T1 RPPH); and RPPH supplemented daily with FS at 0.225% BW (T2) and 0.45% BW (T3). In experiment 3, the aerobic stability of FS was evaluated. (Abstract shortened by UMI.).
