2.3.2. Blood Biochemical Parameters Measurements

Blood glucose (GLU) concentrations were measured via the glucose oxidase method, blood lactic acid (LD) concentrations were measured via the colorimetric method, and blood cortisol (COR) was measured via the double antibody sandwich method with an enzyme-linked immunoassay kit. All samples were tested according to the operating instructions of the kit (Jiancheng Institute of Biological Engineering, Nanjing, China).
