The experiment will be conducted at the Department of Morphology and Physiology, at 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 with water diet 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 in 600 fertile eggs, to set the dosage that promotes better bone embryonic development. Broilers from eggs with improved concentrations of vitamin D (determined at the stage of growth) are used for the creation phase, which receive different concentrations of water containing AS until 42 days of age. The design of the first phase of the experiment (incubation) will be in blocks with five treatments (injection levels of vitamin D) and the design of the second phase of the study will be randomized in factorial scheme 5 x 2 (different concentrations of AS in the breeding period x application of concentration of vitamin D during the incubation period). Data will be analyzed using the SAS ® by polynomial regression models.
