Effects of cinnamon oil ( Cinnamomum Zeylanicum L. ) supplemented to ration on growth performance and carcass characteristics in heat–stressed japanese quails

Abstract

This research was carried out to determine the effects of cinnamon oil (Cinnamomum zeylanicum L.) added to diet at various concentrations on growth performance and carcass characteristics in heat stressed quail (Coturnix coturnix Japonica). The quails (n=180, 15 days age), which were exposed to two different temperatures (Thermo-neutral and heat stress) and three different concentrations of cinnamon oil (0, 250 and 500 mg/kg), were divided into 6 groups according to 2x3 factorial design. All groups were balanced according to initial live weight and gender. Effect of the heat-stress was found to be significant on live weight (P
