Abstract:

the experiment was carried out to evaluate the effect of physical form diet (mash or pelleted) and inclusion of dehydrated egg (degg) up to 21 days of age on the performance and carcass characteristic of cobb-500 strain of broiler chicks at 42 days of age. the birds with average weight of 42.94 ± 0.51 g were allotted in pens of 1.0 x 1.5 m. the experimental design was completely randomized in factorial arrangment with two levels of degg (0 and 0.5%) and two physical form of diet (mash and pellet), resulting in four diets with 18 replicates of 16 birds during the phases from 1 to 7; 8 to 21; 22 to 33 and 34 to 42 days of age. the degg inclusion in the pre initial and initial diets did not influenced the performance, but the pelleted diet improved the performance of for broiler chicks up to 42 days. the pelleted diet also improved breast, pectoralis minor and fillet of breast yields in relationship to carcass weight, and increased the proventriculus and small intestine weights, while the mashed diet increased the gizzard weight.
