  Dietary manipulation of heat induced oxidative stress is one of the most widely used method to alleviate the negative effect of heat stress. The combination of two or more potential antioxidants are known to protect against heat stress. Therefore, 200 day old broiler chicks were raised under hot climate to determine the effect of ascorbic acid and zinc bacitracin and their combination as antioxidants. Birds were divided into four treatments; the first treatment (T1), the control was provided with basal diet. Second (T2) and third (T3) treatments were provided with 1 g ascorbic acid and 100 mg zinc bacitracin per kg basal diet, respectively. The fourth treatment (T4) was provided with a combination of T2 and T3 for 42 days. Performance parameters were reported every fortnight. Blood samples were collected every fortnight and the harvested sera were used to determine oxidative stress biomarkers. Ascorbic acid and zinc bacitracin were safe for heat stressed birds since the liver and kidney function indicators were not changed. Ascorbic acid and zinc bacitracin lowered lipid peroxidation level (Malondialdehyde; MDA) and increased the activity of catalase (CAT), glutathione-S-transferase (GST) and Super Oxide Dismutase (SOD) whereas, glutathione peroxidase (GPx) activity remained unchanged in all treatments. Serum ascorbic acid concentration was significantly (p<0.05) increased accompanied with hypocholesterolemia in heat stressed broilers receiving ascorbic acid compared to the control. Performance parameters were not influenced by feed additives. In conclusion, ascorbic acid was more potent than zinc bacitracin and their combination in increasing the level of enzymatic and non enzymatic antioxidants.

  Production of eggs of low cholesterol level is a prerequisite of modern studies to provide healthy food for human consumption. The present study was performed to assess the effect of canola oil (1 and 2%) on egg production, egg quality and biochemistry of plasma and egg yolk of laying hen. To achieve this goal, 75 hens (hisex, 26 weeks old) were divided into three treatments (25 hens for each) of 5 replicates (5 hens for each). In the first treatment, hens were fed basal diet free of canola whereas 1 and 2% canola oil were incorporated in the second and third treatment, respectively for eight weeks and all data were recorded on 4 and week 8 of the experiment. The current study revealed insignificant difference in feed intake, feed conversion ratio, egg production, egg weight, shell thickness, haugh units and egg yolk color among treatment groups. Plasma triacylglycerol and cholesterol values reduced significantly (p<0.05) in layers fed diet supplemented with canola oil after 8 weeks compare to control. Egg cholesterol values were reduced significantly (p<0.05) in eggs produced by hens supplemented with both concentrations of canola oil for 4 and 8 week compare to control. Liver and kidney function were not affected in all treatments throughout the study. Based on the current results, inclusions of 1% canola oil in layers diet were quiet enough to reduce plasma and egg cholesterol. These results open new perspectives on economy of poultry industry for production of healthy food (egg) for human consumption.

  This study was conducted to determine the normal values of haematological parameters in adult dry, lactating and camel calves. The Hb, PCV, RBC, MCV, MCH and MCHC were lowest in young camels (3-12 weeks old). The above values were generally lower in lactating females as compared to adult dry females. The TLC was highest in young camels and lowest in lactating females. The DLC revealed that the neutrophils were the most predominant cells, followed by the lymphocytes, the eosinophils, the monocytes and finally the basophiis. However, statistical analysis of the DLC showed no significant differences between the three groups, with the except of the eosinophils which were significantly lower (p<0.05) in young camels.

  Serum and hepatic concentrations of Cu, Zn, Fe and Mn of dromedary camels were determined and compared with respective values of cattle and sheep. Serum Cu and Mn concentrations were significantly higher for camels than for cattle and sheep. Serum Fe concentration was significantly lower for camels than for cattle and sheep. Liver Cu concentration was significantly higher for camels than for cattle and sheep. The differences in serum Zn, liver Zn, Fe and Mn between the three species were not statistically significant.
