Mineral composition and in vitro solubility rates for seven different Calcium (Ca) sources, and their feeding effects on performance and digestibility of calcium and phosphorous in broiler chickens were assessed. The experiment used a 6 × 2 factorial arrangement with 12 diets formulated to contain of 6 Ca sources and 2 levels of particle size (<0.05mm and > 1.0-2.0 mm) and one diet as a control...
an experiment was conducted to evaluate the effects of high dietary levels of selenium (as sodium selenite) and copper (as copper sulphate) on growth performance, serum biochemical parameters and antibody production against newcastle disease vaccine (ndv) virus in broiler chickens. a total of 160 ross 308 unsexed day old broiler chickens were randomly allocated into four treatment groups (n=40 ...
This study was carried out to investigate the effects of in ovo feeding of L-carnitine and Satureja Khuzistanica extract on hatchability, post-hatch performance and carcass traits in broiler chickens. A total of 560 fertile eggs of Ross 308 strain (36-wk-old breeder flock) were assigned randomly to seven treatments with four replicates and 20 eggs per replicate. Treatments included control grou...
This study was carried out to evaluate the effect of onion extract on growth performance, carcass characteristics and some blood metabolites in Ross and Cobb broiler chickens. One hundred sixty, 1-d-old broiler chickens (mean initial weight: 36.5 ± 1 g) of male sex (Ross-308 and Cobb) were randomly conducted as randomized complete design with 4 treatment and 4 replication.

An experiment was conducted to evaluate the effects of high dietary levels of selenium (as sodium selenite) and copper (as copper sulphate) on growth performance, serum biochemical parameters and antibody production against Newcastle disease vaccine (NDV) virus in broiler chickens. A total of 160 Ross 308 unsexed day old broiler chickens were randomly allocated into four treatment groups (n=40 ...
This study was performed to evaluate the effect of Myrtle essential oil (MEO) on intestinal morphology, antibody titres and blood parameters of broiler chicks. A total of 180 Ross 308 broiler chickens were allocated to 5 dietary treatments with 3 replicates of 12 birds each. The experimental diets consisted of diet free of antibiotics (control diet), supplemented diets with MEO at levels of 100...
The effect of cinnamon and turmeric powders on performance, and blood parameters of broiler chickens under heat stress were investigated. 200 one-day-old male chicks (Ross 308) were used in a completely randomized design with four treatments and five replicates with 10 birds in each replicate. All birds were treated with heat stress (32οC) and were either fed no any supplement (control), or 0.5...
Abstract The study aimed to assess the effect of dietary inulin (1% inclusion) supplements on broiler chickens’ meat antioxidant compounds. experiment was carried out under heat-stress conditions, 60 Ross 308 chickens. took place in an experimental hall with digestibility pens and controlled humidity, ventilation light regime. Each treatment (2 groups, C E) replicated 6 times 5 chicks per repli...
