  The present study examined the possible role of reactive oxygen species in the pathogenesis of heart failure in broilers. The experiment was conducted with 160, 1 day old male broilers (Ross 308) to investigate to clarify the mechanism of cell injury causing the pathogenesis of PHS syndrome. The chickens were divided in 2 groups of 4 replicates and 20 chicks for any replicate. One group of these chickens was raised in Normal Temperature (NT) treatment and the other group was raised in Cold Temperature (CT) treatment for induce pulmonary hypertension syndrome. Mortality was inspected to determine cause of death and diagnose of heart failure. Hematological, biochemical and pathological tests were used to determine the incidence of PHS including total Red Blood Cell (RBC), Hemoglobin (HGB), Hematocrit (HCT), release of Alanine Transaminase (ALT), Aspartate Transaminase (AST), Lactate Dehydrogenase (LDH) and a best indicator of lipid oxidation subsequent to generated oxidative stress was Malondialdehyde (MDA). Sampling of blood and liver tissue were determined at day 21 and 42. At end of the experiment (week 6), 2 chicks from each replicate were randomly selected and slaughtered. The heart was removed; the right ventricle was dissected away from the left ventricle and septum then ratio of Right Ventricle weight to Total Ventricle weight (RV/TV) calculated too. The results of the experiment indicated that there was a significant difference in RBC, HBG at 21 and HGB, RBC, HCT at 42 between groups as CT group had a greater (p<0.05) HGB, RBC at 21 and HBG, RBC, HCT at 42. However, there was no significant difference in ALT, AST and LDH plasma levels between groups at day 21, CT group had greater (p<0.05) levels in AST, ALT and LDH at day 42. The levels malondialdehyde equivalents an indicator of lipid oxidation sub-sequent to generated oxidative stress at plasma and liver tissue was significantly higher (p<0.05) in CT group at day 21 and 42. RV/TV ratio and mortality due to ascites, also were significantly affected by treatments as CT group had greater (p<0.05) RV/TV and mortality due to ascites mortality percentage compared to NT group. In conclusion, the results indicated that the deteriration of heart function in modern fast growing broilers in the experimental model is associated with oxidative stress leading to lipid peroxidation and reactive oxygen species may be involved in the pathogenesis of the pulmonary hypertension syndrome in broilers chickens.

  Major objectives of this study were to assess antioxidant protection in plasma and whole liver in broilers with pulmonary hypertension syndrome. The experiment was conducted with 160, 1 day old male broilers (Ross 308). The chickens were divided in 2 groups of 4 replicates and 20 chicks for any replicate. One group of these chickens was raised in normal temperature (control without PHS) treatment and the other group was raised in cold temperature (with PHS) treatment for induce pulmonary hypertension syndrome. Mortality was inspected to determine cause of death and diagnose of PHS. For evaluation of antioxidant status, the parameters that were determined in plasma and liver include: Glutathione Peroxidase (GPX), Superoxide Dismutase (SOD), Total Antioxidant Status (TAS) and Malondialdehyde (MDA). Sampling of blood and liver tissue were determined at day 21 and 42. At end of the experiment (week 6), 2 chicks from each replicate were randomly selected and slaughtered. The heart was removed, the right ventricle was dissected away from the left ventricle and septum then ratio of Right Ventricle weight to Total Ventricle weight (RV/TV) calculated too. The results of the experiment indicated that in plasma (GPX) and (SOD) activity were elevated in broilers with PHS compared to controls. It was also, PHS group had low TAS compared to control. But in liver, just GPX (not for SOD) was elevated in PHS group than control. The levels malondialdehyde equivalents an indicator of lipid oxidation subsequent to generated oxidative stress at plasma and liver tissue was significantly higher in PHS group compared control. RV/TV ratio and mortality due to ascites, also were significantly affected by treatments as PHS group had greater RV/TV and mortality due to ascites mortality percentage compared to control.

  An experiment with 320, 1 day male broilers (Ross 308) was performed to evaluate the effects of Arginine (Arg) and Vitamin E (VE) supplementation on antioxidant status, some biochemical parameters and ascites mortality in broiler chickens with cold temperature induced Pulmonary Hypertension Syndrome (PHS). The chickens were distributed between 16 pens of 20 each and each four allocated to each of experimental treatments. Treatment 1: was the birds fed a commercial corn-soybean meal based diet (control), Treatment 2: the birds fed the control diet supplemented with 400 IU VE kg-1 of feed (VE), Treatment 3: the birds fed the control diet supplemnetd with 0.3% Arg in drinking water (Arg) and Treatment 4: the birds fed the control diet supplemented with 400 IU VE and 0.3% Arg (Arg-VE). At day 14, temperature was reduced to amplify the incidence of Pulmonary Hypertension. Hematological and oxidants status parameters (in serum and liver) were determined at day 21 and 42 of age. Right/Total Ventricular weight ratio (RV/TV) was recorded at the end of the experiment (week 6). The results of experiment showed that Arg birds at day 42 had the lower (p≤0.05) RV/TV ratio and ascites mortality yet had improved growth performance parameters. Red Blood Cell (RBC), Hematocrit (Hct) and Hemoglobin (Hgb) was significantly lower in Arg and Arg-VE birds as compared to other birds at day 42 of age. Plasma Malondialdehyde (MDA) wae significantly lower in Arg and Arg-VE birds as compared to other birds at 42. Plasma Glutathione Peroxidase (GPX) activity was greater (p≤0.05) in both the Arg and Arg-VE birds as compared to other groups at day 42. Plasma and liver Superoxide Dismutase (SOD) activity was not affected by none of the Arg or VE supplementation. In summary level of Arg but not for VE used in this experiment, synchronic, some change effects on MDA and TAS in plasma or hematological parameters had positive effects on cardio pulmonary performance, growth performance and ascites mortality in broiler encounter with low temperature and PHS.
