Abstract

One experiment will be conducted in the poultry facilities at Faculdade de Ciências Agrarias e Veterinárias- Campus de Jaboticabal - SP - Brazil, to evaluate the performance, physiological and anatomical characteristics , behavior and carcass yield of broilers submitted at different conditions of rearing temperature, proceeding from eggs injected with ascorbic acid (AA), submitted or not to caloric stress. The experiments will be constituted of two phases (incubation and rearing). In the incubation phase, two experiments will be carried out involving different temperatures of incubation (with or without caloric stress). In each experiment 1.000 eggs will be used. The experimental design will be entirely at random, with 5 treatments (levels of AA application) and 200 eggs/treatment. After the analysis of the data from the incubation experiments, two others experiments will be conducted using 2.160 one- day-old chickens in each one. The experiments will be entirely at random in a factorial design 3 x 4 (3 levels of AA application and 4 rearing temperatures) with 6 replications of 30 birds each. The birds will be reared in climatic chambers and the data will be analyzed by SAS ® program. From the experiments in the incubation phase, data will analyze by polynomial regression models. From the experiments in the climatic chambers, in case of significant interaction, the means of the AA levels will be analyzed, within each temperature by polynomial regression models. In case of no significant interaction, means from the temperatures will be compared by Tukey test at the level of 5% of probability.
