| Abstract | |
Two experimental rehearsals were accomplished in order to evaluate the supply of wet feed for broilers chickens and commercial layers. The experiments were ccomplished at the experimental hangars of male chickens and posture the section of aviculture of the University of São Paulo - Campus of Pirassununga. Nine hundred sixty male chickens were used distributed, with 6 treatments (level of inclusion of water in the diet: 0%, 10%, 20%, 30%, 40% and 50%), were randomly assigned, with four repetitions of fourty birds each a, being appraised body weight gain, feed conversion and feed intake. In the day of the lodging and to the 7 and 21 days, two birds for repetition were abated for the evaluation of the intestinal morphology. For the layers, 192 birds were used, also distributed entirely in delineamento casualizado and divided according to the level of inclusion of water in the diet, were randomly assigned with four repetitions of eight birds each. In this case, they were certain feed intake, feed conversion, eggs production, specific gravity, thickness of the peel and eggs weight. The corporal temperature of two birds was weekly monitored by repetition of both experiments. The wet feed provided a better reduction in the feed intake and better alimentary conversion in both experiments. (AU) | |
