ETLİK PİLİÇLERDE SICAK İKLİMDE SOĞUK SU VE YERLEŞİM SIKLIĞININ OKSİDATİF METABOLİZMAYA ETKİSİ

The present experiment was conducted to investigate the effect of drinking water temperature and stocking density (SD) on oxidative metabolism in heart, liver, bursa fabricius, thymus broiler chickens raised under heat stress. comprised 360 one-day-old Ross 308 male randomly divided 6 experimental groups with 4 replicates each group. Experimental treatments included three different SD (low = 12 birds/m2, medium 15 birds/m2 or high 18 birds/m2) two (10oC 31oC) a 3 x 2 factorial arrangement. At end (42 days age), birds per replicate were euthanized for sample collection. results indicated increased damage caused an increase MDA formation liver thymus. On other hand, cold ameliorated due In study, statistically non-significant interaction generally determined between cage antioxidant system. Besides, while administration CAT activity heart tissues, decreased GSH activity. conclusion, are key environmental factors effecting when broilers conditions; however, more studies needed terms interactive effects enzymes current conditions.
