Abstract

Aluminum has a strong presence in our dally lives, with various possibilities of contamination for the human being and other animals though the ingestion of aliments or addictives present in them or though medicaments. Because it carries a strong electric charge, a strong polarization power and caries similar characteristics as elements of hidroxyapatite, aluminum acts as a competitor of nutrients and can, consequently, cause harm to living being's health. Seeing that, the present research has as objectives to study the influence that different levels of aluminum in the diet of Ornit quail have in the physical and chemical characteristics of the bones and eggs. The bone density and porosity will be determined though de immersion in water method, using the Arquimedes's principal. The productive performance e internal and external quality of the eggs will be periodically analyzed. Using the physical-chemical method (GFAAS) the levels of aluminum present in the samples will be measured so that they can be related with the density and e egg quality. (AU)
