Effect of Orange Peel Essential Oil and Thermotolerance Acquisition on Oxidative Stress Parameters of Liver, Heart and Spleen in Heat Stressed Japanese Quails

Bu çalışmada, Japon bıldırcınlarında erken yaşta stres uygulamaları sonucu termotolerans kazandırılması ve portakal kabuğu esansiyel yağının yeme ilavesinin akut sıcaklık stresinde karaciğer, kalp ve dalak dokularının antioksidan durumlarına etkileri incelenmiştir. 168 adet 7 günlük yaşta Japon bıldırcınları, 24 saatlik açlık veya sıcaklık stresi uygulaması ve bunların yeme portakal kabuğu esansiyel yağı (300 ppm) katılan alt grupları olacak şekilde altı gruba ayrılmıştır. Kesim yaşına gelen bıldırcınlara uygulanan akut sıcaklık stresi organlarda antioksidan sistemleri etkilemiştir. Portakal kabuğu esansiyel yağı ilavesi Malondialdehit (MDA) düzeylerinde düşmeye neden olurken enzim aktiviteleri üzerine etki etmemiştir. Erken yaşta sıcaklık ve/veya açlık uygulamaları ile seçilen organlarda antioksidan sistemler olumsuz yönde etkilenmiştir. Portakal kabuğu esansiyel yağı dokuları lipid peroksidasyonundan koruyabilir ve sıcaklık stresinde doğal antioksidan yem katkısı olarak kullanılabileceği kanısına varılmıştır

Portakal Kabuğu Esansiyel Yağı ve Termotolerans Kazandırmanın Sıcaklık Stresine Tabi Tutulan Japon Bıldırcınlarında Karaciğer, Kalp ve Dalakta Oksidatif Stres Parametrelerine Etkisi

The aim of this study was to determine the effects of orange peel essential oil intake by feed and thermotolerance acquisition by early age treatments on antioxidant status of liver, heart and spleen in Japanese quails which subjected to acute heat stress. 168 seven-day-old quail chicks were randomly assigned to six groups as the control; thermal conditioning and fasting for 24 h fed with basal feed or 300 ppm orange peel essential oil added feed. Acute heat stress at marketing age was affected antioxidant systems of selected organs. Orange peel essential oil supplementation decreased Malondialdehyde (MDA) levels while no effect was observed on enzyme activities. Fasting and thermal conditioning at early age negatively affected the antioxidant status of selected organs. Orange peel essential oil may prevent tissues from lipid peroxidation and can be used as a natural antioxidant supplement in heat stress
