  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.

  Previous study demonstrated that, Ascorbic Acid (AA) was more potent than Zinc Bacitracin (ZB) and their combination in increasing levels of serum enzymatic and non-enzymatic antioxidants of broiler chickens reared under hot climate. However, the levels of these enzymes in the tissues of these birds were not estimated earlier. Previously, 200 day old broiler chicks 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 AA and 100 mg ZB/kg basal diet, respectively. The fourth treatment (T4) was provided with a combination of T2 and T3 for 42 days. At the end of the experiment, liver, heart and kidney tissues were collected and stored frozen until used in the current study for analysis of biochemical markers of oxidative stress. AA and ZB either alone or in combination significantly decreased the lipid peroxidation level (Malondialdehyde; MDA) and increased the activities of glutathione peroxidase (GPx) in all examined tissues compared to the control untreated heat stressed birds. Catalase (CAT), Glutathione-S Transferase (GST) and Glutathione Reductase (GR) activities were only increased in the liver of heat stressed birds treated with AA. However, GST and GR activities were also increased in heart of heat stressed birds treated with either AA or ZB compared to control. In conclusion, AA was more potent than ZB and their combination in increasing the level of enzymatic antioxidants in tissue of heat stressed birds.

  Embryonated egg is an ideal, environment in which to investigate the effects of incubation temperature on the development of the chick embryo. The objective of the current study were to investigate the effect of increasing the incubation temperature of chick embryo by 1.2°C for 7 days (ED4 to ED11) on the body movement and mass of native saudi chick embryo. This objective was extended to examine the influence of pre-hatching temperature on post-hatching growth. Therefore, a total of 180 hatching egg of native Saudi chicken divided into two equal groups incubated at temperature 37.5°C. The incubation temperature was raised to 38.7°C from ED4 to ED11 in treated group before being returned to the control group incubation temperature (37.5°C). The study revealed that elevating the incubation temperature of the eggs of native Saudi chicken by just 1.2°C, from 37.5 to 38.7°C, during embryonic days (ED) 4-11 causes significant increase in embryonic movement as demonstrated in day 8 in the chicks incubated at 38.7°C together with an increase in embryonic development, the embryos incubated at higher temperature were heavier in weights and exhibit significantly longer legs than the controls in ED12 and 15. The increase in pre-hatching incubation temperature (38.7°C) did not reveal any significant effects on post-hatching growth or of feed conversion efficiency.
