| ABSTRACT The present study aimed to evaluate increasing levels of fish waste oil in laying hens diets on performance, egg quality, and sensory features of the eggs. 192 Hisex White laying hens with 29 weeks of age were used, with water and food ad libitum. The experimental design was completely randomized consisting of eight treatments corresponding to the inclusion levels of fish waste oil (0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 and 3.5%) in the diets, with four replicates of six birds each. Data collected were subjected to polynomial regression at 5% of significance. Differences (p<0.05) were observed in feed intake and egg mass. Feed intake increased until 2.50% of fish waste oil in the diets. Differences were not observed (p>0.05) in all variables... |

| ABSTRACT This study aimed to evaluate the inclusion of pirarucu by-product acid silage meal in diets for laying hens on performance and egg quality. One hundred sixty eight Hissex White laying hens 73-wk-old were distributed in completely randomized design with seven treatments (0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0%) and four replicates of six birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of pirarucu by-product meal levels were determined by polynomial regression. Differences (p<0.05) were observed in all variables of performance, in egg weight, yolk height and yolk pigmentation, with pirarucu by-product meal inclusion in diets showed better results than control diet. The pirarucu by-product acid silage meal can... |
