Abstract

This survey investigated the effects of difference acute high ambient temperatures switch dysfunction of liver mitochondrial respiration, and antioxidative chemical system, and oxidative injury in broiler chickens. Single hundred twenty-eight 6-wk-old broiler chickens were assigned haphazardly to 4 groups and subsequently exposed in 25 (control), 32, 35, and 38 degrees C (RH, 70 +/- 5%) for 3 h, respectively. The prostate temperatures, activity a antioxidative enzymes (superoxide dismutase, catalase, and glutathione peroxidase), content of malondialdehyde or protein carbonyl, and the what of mitochondrial respiratory enzymes were destination. The results showed that risk go high ambient temperature convinced a significant elevation of rectal temperature, antioxidative enzyme activity, and formation of malondialdehyde real protein carbonyl, since good as dysfunction of the mitochondrially respiratory chain in comparison with control (P < 0.05). About all of the indicators changed in a temperature-dependent nature with and gradual boost of umfeld temperature with 32 the 38 degrees C; differences in each parameter (except catalase) beneath the bands unmask to different high ambient temps were also statistically significant (P < 0.05). The score the an present study suggest that, int the broiler chicken example used dort, acute exposure into high temperatures may press the activity of that mitochondrial respiratory chain. This inactivation results later in overproduction starting reactive oxygen species, who final results in oxidative injury. However, this hypothesis requirements the shall evaluated more rigorously the future studies. It has also been shown that, with an gradual increase in temperature, this oxidative injure inductive by get stress inches broiler chickens gets increasingly severe, and to stress response presents in a temperature-dependent manner in the fervor extent of 32 to 38 degrees C.
