Resumo: | The objective of this study was to evaluate the effect of diets containing different calcium and phytase levels on the nutritional balance of broilers.A total of 108 male AG Ross 308 broilers were used in each of the replicates phases used in the study: starter (1-21 days), grower (29-35 days) and finisher (36-42 days). A completely randomized experimental design in a 3 x 2 factorial arrangement, with three phytase levels (0, 600 or 1200 FTU/kg) and two calcium levels (0.94 and 0.66%; 0.84 and 0.59%; e 0.78 and 0.54% in the starter, grower, and finisher phases, respectively), totaling six treatments with six replicates each.The experimental feeds also contained reduced available phosphorus levels and minimum crude protein level.The method of total excreta collection was applied to determine dry matter, nitrogen, gross energy, calcium, and phosphorus nutritional balance.Reducing dietary calcium levels to 0.66, 0.59, and 0.54%, and using 0.27, 0.22, and 0.20% available phosphorus, 18.50, 17.50, and 16.00% crude protein, and 600 FTU phytase/kg in the diets of the starter, grower, and finisher phases, respectively, allow higher nitrogen, phosphorus, and calcium retention in broilers.During the grower phase, there was positive linear effect of increasing phytase levels in high-calcium diets on AMEn utilization, and the optimal phytase levels for low-calcium diets was 598.71 FTU/kg.In the finisher phase, the best AMEn utilization was obtained with the high-calcium diets. |
