It was aimed to evaluate the effect of including the waste from passion fruit pulp extraction in diets for Japanese quail in the laying phase on their production performance and egg quality. A total of 280 female quail were distributed into five treatments with eight replicates and seven birds per cage. Treatments consisted of 0, 2, 4, 6, or 8% inclusion of passion fruit waste in the diet. The experiment began with quail at 70 days of age and lasted 63 days, with performance evaluated every 21 days and egg quality in the last two days of each cycle. There was no difference between the treatments for feed intake, body weight, specific gravity, or eggshell thickness. However, a decreasing linear regression was obtained for feed intake with the... |

The aim of this study was to evaluate the action of the phytase enzyme in diets formulated with variations in the crude protein content on performance and egg quality of commercial layers. A total of 336 commercial layers were housed at eight birds per cage in a 3 × 2 factorial arrangement with seven replicates. Treatments consisted of four crude-protein levels (17, 15, and 13%) and two enzyme levels (0 and 500 FTU kg-1 diet), distributed in a completely randomized design. Feed intake, egg production, feed conversion per dozen eggs and per kilogram, egg weight and mass, specific gravity, eggshell thickness, and Haugh unit were measured over five 28-day periods. The performance of commercial layers fed the diet containing 13% crude protein worsened,... |
