Physiological variations and influence of age and gender on poultry of heavy lineage of chicken´s biochemical profile during the rearing stage

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.

摘要 本研究旨在对比乌贝兰迪亚-米纳斯吉拉斯州（Uberlândia-MG）某工业化养殖场内，4周、12周及20周龄重型品系肉鸡的血液葡萄糖、血清代谢酶及矿物质水平。研究人员先对家禽称重，随后于三个日龄阶段分别采集每种性别各15只家禽的血液样本。将分离获得的血清置于全自动生化分析仪中检测以下指标：总蛋白、白蛋白、球蛋白、尿酸、胆固醇、甘油三酯、碱性磷酸酶、γ-谷氨酰转移酶、天冬氨酸氨基转移酶、丙氨酸氨基转移酶、肌酸激酶、钙及磷。每份样本采集完成后，即刻使用血糖仪检测葡萄糖水平。家禽在养殖周期内出现的生理与代谢变化，会导致多数检测指标的血清生化水平发生波动，对比不同日龄与性别组别时，差异均具有统计学意义（P<0.05）。
