the effect of silver nanoparticles as additive on broiler performance was investigated through employed of 312 day-old broiler chiks (arbor-acre plus) in a completely randomized design with 6 treatment diets each in 4 replicates. corn- soy based diets were formulated for starter, grower and finisher according to nrc (1994) recommendations. the silver nanoparticle solutions (2000 ppm) were added...

abstract: this study was conducted to investigate the effects of diets containing different levels of hull-less barley on caecal microflora of broiler chicks. two hundred and forty one-day old male broiler chicks (arbor acres strain) were used in a completely randomized design with 4 tratments, and 3 replicates were allocated to each treatment. different levels of hull-less barley in diets had ...

Ascites syndrome is indicating the abnormal accumulation of non-inflammatory fluid in abdominal space. Hypoxia is the most important cause of pulmonary hyper blood pressure in broiler poultry. The aim of this study is a comparative survey of ascites syndrome incidence rate in Ross, Arbor-Acrese and Cobb strains of broiler chickens. For this purpose, 150 broiler male chicks of Ross, Cobb, and Ar...

in this study, 480 on-day-old arbor acres broiler chicks were used in a 2*3 factorial arrangment with 2 levels of hull-less barley (0.30%)and 3 levels of enzyme (0.300 and 600g/ton), to investigate the effect of diets containing high soluble non-starch polysaccharides (nsps) concentrations on morphological characteristics of small intestine and performance of broilers. increasing in concentrati...

The effect of light regime and feeding system on broiler performance, carcass traits, serum hormones and metabolic profiles was studied using eight hundred and ten one-day-old broiler chicks from Arbor Acres strain. Broilers were distributed randomly in 3 by 3 factorial arrangement. Three light regimes, (continuous light (23L: 1D), constant light (15L: 9D) and intermittent light (4L: 8D)) were ...

The Effect of Different Sources Selenium and Microencapsulation on Fertility Hatching Traits in Arbor Acres Broiler Breeder

The effects of antibiotic, probiotic, and prebiotic as dietary feed additives on carcass composition as well as Salmonella counts and its serotypes in droppings and intestine of broiler chickens on days 1, 28, and 56 of experiment were investigated. Dietary treatments were control diet (basal diet without additives), OXYT diet (basal diet with 600 ppm of the antibiotic oxytetracycline), GRO-UP ...

A semi-field study was carried out to evaluate the effect of two medicinal herbs, individually and in combination, on growth performance, carcass traits, nutrient digestibility and immune response of broiler chickens.  A total of 384 one-day-old straight-run Arbor Acres broiler chickens were allocated into 24 floor pens prepared in a commercial broiler house. Pen-groups were fed one of the foll...

The aim of this study was to assess the effects of purified polymannuronate (PM) obtained from marine brown algae on the performance, antioxidant capacity, immune status, and cecal fermentation profile of broiler chickens. In a 42 d experiment, 540 (average BW 43.77±1.29 g) 1-d-old Arbor Acres male broilers were randomly divided into 5 treatments with 6 replicates of 18 chicks and fed a corn an...

One hundred and eighty 28-days-old Arbor Acres broiler birds were utilized in a 28 day experiment to investigate the effect of replacing bone ash with eggshell meal in the diet of broiler birds on their nutrient digestibility and blood parameters. Five experimental diets tagged T1, T2, T3, T4 and T5 were formulated to be isocaloric (2865.53 kcal ME/kg) and isonitrogenous (20% crude protein) suc...
