| Sumario: | In this paper we describe the main productive variables in a female broiler chickens flock fed with two levels of energy / protein. Were used 192 chickens housed in 16 boxes with 12 birds each one, being each box an experimental unit. We performed a repeated measures analysis to evaluate the treatment effects along the time. There were no statistically significant differences between treatments for body weight (p = 0.76) with averages accumulated of 3,087 g ± 96 g and 3100 g ± 92 g at the end of the cycle, neither for food intake 5.718,96 g ± 412.01 g 5.764,81 ± 429.15 g. Feed conversion showed the same performance, with cumulative values of 1.85 ± 0.09 and 1.86 ± 0.12 (p = 0.94). Both diets presented strong percentage of uniformity variations over the cycle, with no detectable differences (p = 0.27). The results obtained under the experimental conditions, indicate that the best diet would be the highest ratio of energy / protein, especially all isocaloric diets and considering the fact that the reduction in protein levels held about costs ration. |
