EFFECT OF THE DIETARY PELLET:MEAL RATIO ON THE PRODUCTIVE PERFORMANCE OF LAYING HENS
Abstract
The effect of dietary pellet:meal ratio on the performance of laying hens was evaluated using 60 Plymouth Barred Rock 30 week old hens. Hens were distributed at random to three treatments: 100:0, 75:25 and 50:50% of pellet:meal ratio in the diet along 49 days, with 20 replicates each. Final body weight of hens, polar and ecuatorial diameters of the egg, eggshell weight, eggshell thickness, and yolk colour were not different between treatments (p>0.05). However, egg production, egg weight, egg mass, food consumption, food conversion and production cost were affected by treatments (p
