Reoviruses are important pathogens responsible for poor growth performance and silent losses in the poultry industry. They are associated with many disease and syndromes such as malabsorption (runting and stunting syndrome), respiratory diseases and immunosuppression. Broiler birds are most susceptible to viral infections during the early post hatching period. Therefore, the transfer of materna...

This study was carried out to investigate the nutritional values of soybean meals (SBM) from various geographic origins and the effects of their dietary supplementations on performance of broiler chicken. Nutritional values of dehulled SBM originated from USA, and nondehulled SBM from India (IND) and Argentina (ARG) were evaluated by analyzing chemical composition, urease activity(UA) and KOH s...

This experiment was conducted to evaluate the effects of ochratoxin A (OTA) on the function and histology of the liver, kidney and bursa of broiler chickens fed OTA contaminated rations. Two hundred forty one-day-old male Ross broiler chicks were used, they were randomly divided into 3 dietary experimental groups of 80 birds and given rations containing 0 (control), 400 or 800 μg OTA/Kg feed. T...

Phytogenic feed additives are used as antibacterial, anti-inflammatory and performance enhancer in the nutrition of broiler chicks. In present study, it was aimed to investigate effects usage phytogenic which an alternative antibiotics broilers at different levels rations, on morphology duodenum ileum. For this purpose, 48 male ROSS-308 one-day-old chicks were study. Chicks with a body weight 4...

A progressive selection for broiler live and processing performance traits has changed broiler growth patterns during the post hatch period. However, limited information is available to understand whether changes have also occurred during the embryonic stages. This study aims to examine influences of broiler strain on nutrient availability, embryonic development, and nutrient metabolism during ...

This study aimed to investigate and compare nonlinear growth models (NLMs) with the predicted performance of broilers using an artificial neural network (ANN). Six hundred forty broiler chicks were sexed and randomly reared in 32 separate pens as a factorial experiment with 4 treatments and 4 replicates including 20 birds per pen in a 42-day period. Treatments consisted of 2 metabolic energy le...

This study was conducted to determine the effects of sumac, yeast, and onion supplementation broiler chicken feeds on performance. Four hundred fifty, one-day-old Ross 308 chicks were obtained from Yagoo Group Hatchery in Sulaymaniyah Province randomly distributed into three treatment groups (150 for each group) with six replicates (each 25 chicks). Chicks raised floor cages (210 × 200 100 cm)....

Reduction in exercise increases the occurrence of lameness in meat-type chickens. Locomotor activity is dramatically reduced during the finishing period in chickens from fast-growing genetic types compared to slow-growing genetic types, but it is not known whether this difference is already present during the starting period and may be influenced by genetic factors. In order to define the effec...

The main purpose of this study was to investigate the effects of Euphorbia hirta and acidifiers supplement on resistance of broiler chickens against Salmonella enteritidis infection. A total of 120 day-old male broiler chicks were randomly assigned to 3 dietary treatments. 1) basal diet, 2) basal diet supplemented with 2 g/kg organic acid (OA) and 3) basal diet supplemented with 7.5 g/kg E. hir...

Objective: The aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (CGM) and its effect on growth performance of broiler chicks. Methods: Chemical composition and nitrogen corrected true metabolizable energy of CGM was determined by standard and precision-fed cockerel assay methods.  For evaluating of protein quality, 90 male broiler chicks in a com...
