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, selenium, or their different combinations on immune response and blood biological parameters of broilers raised under either thermoneutral or heat stress conditions. Expand
Lack of Effect of Dietary Chromium Supplementation on Growth Performance and Serum Insulin, Glucose, and Lipoprotein Levels in Broilers Reared Under Heat Stress Condition
This study evaluated the effects of supplemental dietary chromium (Cr) on the performance, carcass traits, and some serum parameters of broilers under a heat stress condition and found that cholesterol concentration decreased in chicks fed Cr L-methionine compared to the control. Expand
Effects of Different Levels of Organic and Inorganic Chromium on Growth Performance and Immunocompetence of Broilers under Heat Stress
It is suggested that supplemental chromium especially in organic form offers a good management practice to reduce heat stress-related depression in immunocompetence of broiler chicks. Expand
Effects of Dietary Selenium and Vitamin E on Growth Performance, Meat Yield, and Selenium Content and Lipid Oxidation of Breast Meat of Broilers Reared Under Heat Stress
Results showed that supplementation of selenium and vitamin E was capable of increasing theSelenium content of the breast meat and could improve the lipid oxidation of the Breast meat when broilers reared under HS condition. Expand
Performance, Egg Quality Traits, and Serum Metabolite Concentrations of Laying Hens Affected by Dietary Supplemental Chromium Picolinate and Vitamin C Under a Heat-Stress Condition
A 3 × 2 factorial experiment consisting three levels of chromium (chromium picolinate) and two levels of vitamin C was employed to evaluate the effects of these dietary supplements on performance, egg quality traits, and serum biochemical parameters of heat-stressed laying hens from 66 to 74 weeks of age.

Selenium as a Feed Supplement for Heat-Stressed Poultry: a Review
An optimum response with supplementation of selenium in diet has been found to improve feed intake, body weight gain, feed efficiency, egg production and quality, and antioxidant status in heat-stressed poultry. Expand
Effects of using eucalyptus (Eucalyptusglobulus L.) leaf powder and its essential oil on growth performance and immune response of broiler chickens.
Dietary EEO has the potential to enhance immune response of broiler chickens and greater primary antibody response to sheep red blood cells compared to the control, but differences in secondary antibody response were not significant. Expand
Comparative assessment of sodium selenite, selenised yeast and nanosized elemental selenium on performance response, immunity and antioxidative function of broiler chickens
Abstract Although selenium (Se) supplementation is a common practice in poultry, the best source and level has not been established yet. Thus, a 42-day experiment involving diets with three levelsExpand
Effects of purslane ( Portulaca oleracea L.) powder on growth performance, blood indices, and antioxidant status in broiler chickens with triiodothyronine-induced ascites
To evaluate the effects of dietary supplementation of purslane powder (PP) on performance, blood indices, and antioxidant status in broilers with triiodothyronine (T3)-induced ascites, 240 one-day-old male broiler chicks were randomly assigned to four treatments. Expand
Effects of enzyme supplementation on replacing maize with barley in diet of broiler chicks
Two experiments were conducted to evaluate the effect of an enzyme complex (Agrozyme®, a cocktail of cellulolytic, amylolytic and proteolytic enzymes) on barley energy content and its nutritive valueExpand
