ABSTRACT
Yang S, Guo D, Yao B., Effect of cold exposure on cardio-hepatic
mitochondrial malonilaldehyde and superoxide
dismutase pulmonary hypertensive syndrome of broilers, Onl
J Vet Res., 29 (10): 612-620,
2025. Pulmonary Hypertension Syndrome (PHS) in broilers is associated with
increased malonyl-aldehyde (MDA) and decreased superoxide-dismutase (SOD)
levels in tissues suggesting a causal relationship between oxidative stress and
pathology. We studied 2 groups of two hundred 21 day old broilers reared at 24
and 12Co, respectively compared up to 49 days of age. In broilers
exposed to 12Co, right (RV) total ventricle (TV) weight ratio
increased 37%, cardio-hepatic SOD activity decreased 25-36% and cardio-hepatic
MDA increased 38-40% suggesting that cold exposure induced cardio-hepatic
mitochondrial membrane oxidative stress by free radicals.
Key words: Ascites syndrome,
Mitochondria, Malonyl-aldehyde, free radicals, antioxidants.
