“…Sahin et al (2003) pointed out that vitamin E supplementation reduced plasma cholesterol level in heatstressed Japanese quails. This result concurs with the finding of Rashidi et al (2010) who showed that the supplementation of vitamin E and zinc to diets of broiler reared under HS decreased serum cholesterol and triglyceride levels.…”

“…The increasing level of plasma glucose may be derived from an increase in free radicals and the release of ACTH and cortisol hormones that prevent insulin release and stimulate gluconeogenesis due to HS (Ajakaiye et al 2010). Likewise, Kutlu and Forbes (1993) and Rashidi et al (2010) found that HS increased plasma glucose level. On the other hand, Tatli Seven et al (2009) recorded that plasma glucose level was not significantly affected by HS.…”

“…They reported that the serum cholesterol and triglyceride levels in broilers were significantly increased by HS compared to TN. The increase in blood lipids under HS was explained by Rashidi et al (2010). They pointed out that HS decreased feed intake of broilers compensate their energy requirement by lipolysis of body lipid that it results in increasing the plasma cholesterol and triglyceride levels.…”

This study aimed to compare the dietary supplementation of oleuropein (O) and α-tocopherol acetate (TA) alone or with organic selenium (Se) on liver antioxidant status and some plasma biochemistry parameters in Japanese quails reared under heat stress (HS). A total of 800, two-weeks old quails were kept in wire cages in the temperaturecontrolled rooms at either 22°C or 34°C for 8 h/d and fed on a basal diet (NC) or the diets supplemented with TA (TA200) or O (O200) at 200 mg/kg alone or with OSe (TA200+OSe and O200+OSe) to the NC diet. HS decreased the total antioxidant status (TAS) and increased the total oxidative stress (TOS) and oxidative stress index (OSI) of liver compared to thermoneutral temperature (TN). The TA200, O200, TA200+OSe and O200+OSe diets increased TAS and decreased TOS of liver compared to those of quails fed NC. OSI was decreased by the TA200, O200 and TA200+OSe diets compared to NC and O200+OSe diets. HS reduced plasma albumin (A) and total protein (TP) concentrations, on the other hand, increased plasma glucose (G), total cholesterol (CHO) and triglyceride (TG) levels compared to TN. The TA200, O200, TA200+OSe and O200+OSe diets reduced plasma total CHO and TG levels and increased plasma A level. The TA200 and TA200+OSe diets reduced plasma G level and increased plasma TP levels compared to those of quails fed the other diets. In conclusion, dietary supplementation of vitamin E and oleuropein alone or with organic selenium is necessary to remove the negative effects of heat stress on liver antioxidant status and some plasma parameters of quails.

“…(2014) they reported that heat stress enhances lipid metabolism associated with the increase in serum total cholesterol (TC) and triglyceride (TG). This raise in blood lipids under heat stress was explained by Rashidi et al (2010) who pointed out that heat stress reduced feed intake of broilers compensate their energy requirement by lipolysis.

Key words:Quails, Heat stress, Organic selenium and chromium, Immune response, oxidative stress This study conducted to clarify the effect of dietary supplementation of organic chromium (Cr), selenium (Se) and their combination on performance, immune responses, hematological and biochemical parameters as well as antioxidant capacity of Japanese quails (Coturnix japonica) under heat stress. A 90-day trial conducted using seventy-five, 10-day-old Japanese quails that randomly divided into 5 groups of 15 birds each. The 1 st group received basal diet and kept in a temperature controlled room at 24°C. The other four groups reared under natural summer months and kept in a room temperature ranged from (25.3°C to 36.7 °C). The 2 nd group kept under heat stress condition and fed basal diet only. The third, fourth and fifth groups fed basal diet supplemented by chromium (1400 µg/kg of diet), selenium (0.3 mg/kg of diet) and their combination respectively. In heat-stressed quail group, the data of growth performance revealed a significantly (P<0.05) reduced body weight gain (BWG), total feed intake (TFI) and a significantly (P<0.05) increased feed conversion ratio (FCR). A significantly (P<0.05) reduced phagocytic activity (PA), phagocytic index (PI) and the antibody titer against Newcastle disease virus as well as high mortality rate. a macrocytic hypochromic anemia and stress picture of leukogram. A significant (P<0.05) reduction in total proteins, albumin and thyroid hormones concentrations together with a significantly (P<0.05) elevated activity of serum AST, LDH, raised total cholesterol, triglycerides and glucose concentrations. Moreover, a significant (P<0.05) increase for lipid peroxidation marker (MDA) and a significant (P<0.05) reduction of glutathione peroxidase (GSH-Px), and total anti-oxidant capacity (TAC). However, simultaneous dietary supplementation with organic Cr and/or Se alleviated heat stress adverse effects. It could be concluded that combined dietary supplementation of organic Cr and Se can be considered to be a protective management in a quail diet, reducing the negative effects of heat stress.

Effects of dietary selenium and vitamin E on immune response and biological blood parameters of broilers reared under thermoneutral or heat stress conditions

A study was conducted using 360 broiler chickens to evaluate the effects of dietary vitamin E (0, 125 and 250 mg/kg), selenium (Se, 0, 0.5 and 1 mg/kg), or their different combinations on immune response and blood biological parameters of broilers raised under either thermoneutral (TN, 23.9 °C constant) or heat stress (HS, 23.9 to 37 °C cycling) conditions. Humoral immunity was assessed by intravenous injection of 7% sheep red blood cell (SRBC) followed by evaluation of serum for antibody titers in primary and secondary responses. Heterophil to lymphocyte (H/L) ratio also determined as an indicator of stress. Furthermore, at the end of the experiment, birds were bled for determination of some biological parameters. There was a significant reduction in body weight and feed intake, but the feed conversion ratio increased when the birds were exposed to HS (P<0.05). Body weight and feed intake were not influenced significantly by dietary vitamin E and Se (P>0.05), whereas feed conversion was improved significantly by 125 mg/kg vitamin E (P<0.05). The liver and lymphoid organ weights as well as IgM and IgG, antibody titers for primary and secondary antibody responses to SRBC were reduced significantly under HS (P<0.05). Heat stress also resulted in a significant increase in H/L ratio (P<0.05). Dietary vitamin E resulted in improvement of primary and secondary antibody responses both in TN and HS broilers (P<0.05). The HS birds also showed an improved antibody titer in secondary response with high concentration of Se (P<0.05). Vitamin E and Se had interactive effects on anti-SRBC titers; however, no consistent differences were found between dietary levels during the study. The H/L ratio decreased by feeding vitamin E at both levels either under HS or TN conditions (P< 0.05). The serum concentrations of glucose, triglycerides, total cholesterol, and LDL-cholesterol were increased but serum HDL-cholesterol decreased in HS broilers (P<0.05).
