Abstract

The experiment will be conducted at the Department of Morphology and Physiology and the poultry sector of UNESP / Jaboticabal to assess bone development, physiological responses, the anatomical, performance, meat quality and carcass yield of broilers from eggs injected with calciferol (vitamin D) and animals fed diets containing alendronate sodium (AS), in order to find management strategies to minimize the effects of developmental bone, found in poultry during the creation. The experiment will consist of two phases (incubation and rearing). At hatching, there will be an experiment with different levels of vitamin D injection into fertile eggs, to set the dosage that promotes better bone embryonic development. Chicks from eggs with improved levels of vitamin D (determined at the stage of growth) are used for the creation phase, which receive different levels of water containing AS until 42 days of age. The design in the incubation phase is completely randomized with five treatments (injection levels of vitamin D) and for the design phase is completely randomized in factorial scheme 5 x 3 (levels of AS in the breeding period x application levels of vitamin D during the incubation period). Data will be analyzed using the SAS ® by polynomial regression models. (AU)
