byproduct fish processing fish silage
The objective of this research was to evaluate the effect of the inclusion of biological silage of fish residues in the digestibility of various nutrients in sheep. The results showed that the inclusion of different levels of biological silage of fish residues did not significantly affect the digestibility of dry matter, organic matter, neutral detergent fiber, and energy, but it did have a significant effect on the digestibility of crude protein.
The objective of this research was to evaluate the effect of the inclusion of biological silage of fish residues (BSFR) in the digestibility of the dry matter (DMD), organic matter (OMD), crude protein (CPD), neutral detergent fiber (NDFD) and energy (ED). During 21 days (14 for adaptation and 7 for collections), 16 sheeps of Morada Nova crossbreed, caudectomized, with 30 kg of life weight were put in metabolism cages, distributed in a completely randomized experimental design, with four treatments (Levels of BSFR in the diets: T1=0 %, T2=5 %, T3=10 % and T4=15 %) and four replications. There were no significative differences (P > 0.05) for DMD, OMD, NDFD and ED, with the values 65.5, 86.2, 62.1 and 63.1 %, respectively. Its was observated significative differences (P < 0.05) for CPD, which were, 78.0a, 76.9ab, 72.4b and 73.0b, to the treatments T1, T2, T3 and T4, respectively. In the levels evaluated, BSFR is a product of nutritional quality for use as proteic ingredient in diets for sheeps.
