Abstract

This experiment was conducted to evaluated increasing levels of canola meal in laying hens diets formulated based in different amino acid recommendations. 144 commercial laying hens was allotted in laying cages during 4 periods of 21 days. Performance and egg quality parameters were evaluated In the last two days of each period. Hens were distributed in a complete randomized design, in factorial arrangement 2x4, with eight treatments and three replicates of six hens each. The factors were diets formulated based on total and digestible aminoacids and increasing levels of canola meal on these diets (0; 4; 8 and 12%). Recommendations of digestible amino acid promoted worst feed conversion and lower egg mass output. Canola meal can be included in laying hens diets until 8% without decrease performance and egg shell quality. However, canola meal increased feed cost on the region where the experiment was conducted. KEY WORS: Alternative feeding, egg quality, performance, nutrition.
