  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 4 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 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 421 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) was significantly lower in Arg and Arg-VE birds as compared to other birds at day 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.

  A study with four hundred, 1 day old male (Ross 308) broilers that were randomly assigned to 4 treatments with 5 replicate, 20 birds per each was conducted to determine the effect of diet supplementation with Lactobacillus cultures on some blood parameters, plasma enzymes activities and mortality of broiler chicken. For this purpose, the experiment carried out by feeding 4 levels of the probiotic (0, 0.05, 0.10 and 0.15%) to broiler chicks from days 1-42 of age. Hematological, biochemical tests were measured at days 21 and 42; Hemoglobin (HGB), Hematocrit (HCT), release of Alanine Transaminase (ALT), Aspartate Transaminase (AST), Lactate Dehydrogenase (LDH), White Blood Cell (WBC), heterophils, lymphocytes, cholesterol and triglycerides. The results of the recent experiment showed that feeding diet with Lactobacillus cultures (0.15%) to chickens significantly (p<0.05) decreased, ALT and AST activity, cholesterol and triglycerides. Moreover, Lactobacillus cultures (0.15%) significantly (p<0.05) increased HCT, HGB and WBC day 42 of age. Moreover, Lactobacillus cultures (0.15%) significantly reduced chicken mortality compared to the other groups. There are no significant effects of Lactobacillus cultures on other blood parameters.
