ABSTRACT
This study aimed to compare the levels of glucose in the blood and serum´s metabolites enzymes and minerals of poultry of heavy lineage of chicken at the age of four, twelve and twenty weeks in an industrial production unit in the city of Uberlândia-MG. After weighing the birds, blood samples were collected from 15 birds of each gender in the three ages. The serum obtained was evaluated in an automatic biochemical analyzer for the following parameters: total protein, albumin, globulin, uric acid, cholesterol, triglycerides, alkaline phosphatase, gamma-glutamyl transferase, aspartate aminotransferase, alanine aminotransferase, creatine kinase, calcium and phosphorus. Immediately after the collection of each sample, we evaluated glucose levels by means of a glycosimeter. The physiological and metabolic changes that birds present in the rearing age reflected in the variation of serum biochemical levels in most constituents evaluated, showing significant differences (P< 0.05) comparing age and gender.
