The Effect of Heat Stress on Oxidative Stress and Antioxidant Status in Local Quail Hens Supplemented with Onion and Garlic Oils

Abstract

This study was conducted to investigate the potential of onion and garlic oils and their mixture supplementation under heat stress on the egg production, egg weight, total lipid concentration and antioxidant activity of local quail hens. Sixty birds at 42 weeks' age were evenly divided randomly into 4 treatments: feed in control (T0) free of onion and garlic oil, T1 and T2 were supplemented 0.2% in each onion or garlic oil, T3 was supplemented mixture of (0.1% onion + 0.1% garlic oil) respectively. The birds reared in temperature-controlled room (35-38°C) at afternoon. The results of enzymatically analysis of catalase, superoxide dismutase, Glutathion-Px activity concentrations, egg production percentage, egg weight and egg mass had significantly higher (P≤0.05) in the most treatments of onion and garlic oils and their mixture supplemented diet. While, significantly lower (P≤0.05) in total cholesterol, hydrogen peroxide (H2O2) and Malondialdehyde (MDA) in onion and garlic oils and their mixture supplemented diet compared with control of blood serum, liver tissue and egg yolk of quail hens under heat stress.
