This experiment was conducted to study the effect of different levels of levamisole on performance and related parameters with immune system in Cobb 500 strain male broilers. The experiment was carried out a completely randomized design, with 300 male broiler chickens in four treatments and five replicates 15 birds/replicates. The experimental groups consisted of zero, 2.5, 5 and 7.5 mg pe...
We evaluated the effects of dietary Carum copticum essential oil (CCEO) on growth performance, carcass characteristics and intestinal microflora of broiler chickens. A total of 240 Cobb broiler chickens were allocated to five dietary treatments, each with four replicates of 12 birds. Dietary treatments were prepared by formulating a corn-soybean meal-based diet free of antibiotics (Control) and...
A feeding trial was carried out to investigate the effects of lecithin on growth performance, nutrient digestibility, lipid profile, carcass characteristics and meat quality of broiler chickens. A total of 240 oneday- old male broiler chicks (Cobb 500) were obtained from a local hatchery and raised for 42 days. The chicks were divided into 5 dietary treatments. The diets supplemented with prill...
This study was carried out to evaluate the efficacy of Fenugreek seeds (Trigonella foenum-graecum L.) on overall performance broiler. A total 96-day old Cobb-500 chicks were randomly divided into four dietary treatment groups namely 0, 1, 2 and 3 having three replications in each group. Brooded separated wise separate pen rear up 4 weeks. Each group contains 24 birds (8 replication). Experiment...
ghrelin is a peptide hormone that is composed of 26 amino acids and leads to a positive energy balance and obesity through stimulation of releasing growth hormone, and increasing food intake and body weight. the purpose of this study was to determine and evaluate the association between the ghrelin gene polymorphism and growth traits in ross and cobb broiler chickens. blood samples were collec...
this experiment was conducted to evaluate the effect of silver nanoparticles coated on clinoptilolite on performance traits, liver enzymes and blood lipid concentrations to use 375 cobb 500 broiler chickens in completely randomized design with five treatments and five replicates and 15 birds to each replicate. the use of silver nanoparticles coated on clinoptilolite improved feed conversion rat...
the purpose of this study was to determine the incidence of rickets types in broiler chickens on the basis of gross and microscopic lesions in field clinical cases with regard to differential pathomorphological diagnosis.clinical, serological, gross anatomy and histological investigations were carried out in broiler chickens with signs of rickets. the survey included 12 finisher broiler flocks ...
this experiment was carried out for a period of 4 weeks with 240 day old straight- run broiler (cobb-500) chicks to investigate the effects of administering electrolytes in drinking water on the productive performance (live weight, body weight gain, feed consumption, feed conversion and water consumption) and to determine the economic impact of using electrolytes. the chicks were randomly distr...
