FOURTEEN DAYS CYCLIC HEAT CHALLENGE AND FEEDING OREGANUM COMPACTUM AND CURCUMA XANTHORRHIZA ESSENTIAL OILS: EFFECTS ON ANTIOXIDANT SYSTEM OF BROILERS

摘要

Broilers can properly perform if they are not subjected to suboptimal environmental conditions. Ambient temperatures above thethermoneutral zone of birds have been associated with oxidative stress, as reflected in elevated lipid peroxidation productsin blood and tissues, and impairing the oxidative status of broilers (Lin et al., 2006).Numerous studies have been performed in poultry on the effects of various dietary antioxidants on the bird oxidative status and the oxidative stability of their meat postmortem. Synthetic antioxidants and some other antioxidant additives are under significant public scrutiny and have limitations in their use, e.g., their inclusion levels in all feeding stuffs of all species of meat animals are regulated in EU countries. Therefore, there is currently a great interest in exploring the effects of natural compounds.
