Examination of Relationships Between Some Biochemical and Oxidative Stress Traits by Canonical Correlation Analysis in Broiler Chickens

Abstract

Canonical correlation analysis is a multivariate method to examine the relationships between two (X and Y) sets of variables when all measurements are obtained from same broilers. Canonical correlation analysis aims to obtain new variables called as canonical variates formed by linear combinations of the original variables for each set and by maximizing the relationships between two set. The purpose of this study is to examine the relationships between 8 biochemical traits (Aspartate Aminotransferase (AST), Albumin, Triglyceride, Total Cholesterol, Low Density Lipoprotein (LDL) cholesterol, Glucose, Total Protein and Alanine Aminotransferase (ALT)) and 4 oxidative stress traits (total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), lipid peroxide (LPO)) in broiler chickens. As a result, the correlation between the first canonical variable pair was found 0.594.
