Effect of satureja khuzestanica essential oils on postmortem pH and antioxidative potential of breast muscle from heat stressed broiler chicken

Abstract

The aim of this study was to evaluate the effect of Satureja khuzestanica essential oils on antioxidative potential of breast muscle from heat stressed broiler chicken. A total of 720 one dayold Anan broiler chicks broiler chicks were randomly assigned to 6 groups (6 replicates of 20 birds each) to evaluate the effects of administration of Satureja khuzestanica essential oils (SKEO) through drinking water on immune postmortem pH and antioxidative potential of breast muscle from heat stressed broiler chicken The birds were continuously received drinking water treated with Tween 80 (Cont+; 500 ppm) and SKEO at 0 (Cont-), 200, 300, 400 and 500 ppm as six experimental treatments. Breast muscle early as well as ultimate pH values at 42 days of age were non significantly lower for the birds received SKEO through drinking water at doses greater than 200 ppm. Addition of SKEO to drinking water at doses higher than 200 ppm significantly decreased the amount of TBARS values in breast muscle (p<0.05). Breast muscle catalase activity in SKEO received groups were significantly higher than the control groups (p<0.05). It was concluded that supplementation of drinking water with SKEO at dosed higher 200 ppm enhance the antioxidative potential of breast muscle from heat stressed broiler chicken. © 2013 Academic Journals Inc.
