The objective of this study was to evaluate the effects of acid silage meal made of pirarucu waste in diets for commercial laying hens on apparent digestibility and energy metabolism. Seventy-two Hisex White hens with 71 weeks of age were assigned to a completely randomized with two treatments (control diet and diet with 3% pirarucu waste acid silage) with six replicates of six birds each. The ensiled biomass was light brown in color, showing acidified aroma; creamy consistency; 4.38±0.11 pH; 84.16% dry matter; 40.06% crude protein; 26.82% ether extract; 9.31% mineral matter, 65.16 g kg-1 calcium and 22.90 g kg-1 phosphorus. Differences (p > 0.05) were detected in digestibility of crude protein, non-fiber carbohydrates (soluble carbohydrates), etherextract, mineral matter, metabolizable energy and metabolizable energy coefficient. Our results indicate that the acid silage mealmade of pirarucu waste can be included up to 3% in diets for laying hens, showing satisfactory nutrient digestibility and potential to be used as an energy source.
