Effect of summer and winter seasons on blood enzymes of outdoor rearing two quail strains

Abstract

    This study aimed to identify the effect of season on enzymes activity in blood of Two Japanese quail (Coturnix coturnix japonica) strains (white and Brown). Samples of blood from these quails were collected from some outdoor reared at farms in Baghdad city during 2017. Blood serum enzymes activity were determined which included glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and alkaline phosphatase (AP) during summer and winter seasons. Results obtained revealed that significant differences (P<0.05) due to sex were found in blood serum enzymes, also significant differences (P<0.05) were found due to season.
