Conteúdo: | Abstract: The energy values and nutrient digestibility of shrimp waste meal (SWM), obtained from extractive fishing, were determined in 2 experiments with broiler chickens. In experiment 1, 180 broiler chickens were randomly distributed into 5 treatments of 6 replicates with 6 birds each. The corn-soybean meal basal diet (BD) and 4 test diets consisted of inclusion of 50, 100, 150 or 200 g/kg SWM were evaluated. In experiment 2, 240 birds were randomly distributed into 4 treatments (0, 50, 100, or 150 g/kg SWM) of 10 replicates with 6 birds each. Non-inclusion of SWM (0 g/kg) was consisted of a protein-free diet. The metabolizable energy (ME) and nitrogencorrected metabolizable energy (MEn) of the test ingredient (SWM) were determined by the regression method. Dry matter (DM), crude protein (CP), ether extract (EE) and ash were 890, 326, 39, and 411 g/kg, respectively and the respective gross energy (GE) was 9.98 MJ/kg. The inclusion of SWM to the BD, linearly decreased (P < 0.05) dry matter intake, the digestibility of DM, Ca, and P, and the energy digestibility; however, nitrogen and sodium retention increased. Regressions of SWM-associated ME or MEn intake in Mj against SWM intake were: ME=0.1858+6.524x, r2=0.98; MEn=0.1290+5.467x, r2=0.91. The data indicated the respective ME, MEn values (MJ/kg of DM) of SWM were 6.524 and 5.467. The level of 100 g/kg provided the highest digestibility of crude protein and of the amino acids threonine and serine, besides energy availability on a DM basis. Shrimp waste meal obtained from extractive fishing showed nutritional characteristics that enable its use in the feeding of broilers.
