This study was conducted to determine the effects of three different fat sources and their combination on growth performance, carcass traits and intestinal measurements of broiler chickens reared to 42 d of age. Two hundred day-old male broiler chicks (Ross 308) were randomly assigned to one of five treatments with four replicates of 10 chicks based on a completely randomized design. The dietar...

A total of 480 Arbor Acres Broiler chicks (mixed sex) from 1 to 35 days age were divided randomly into 4 treatments evaluate the impact defatted Scenedesmus obliquus biomass (DAB) on broiler performance. The DAB was supplemented diets with levels 0, 0.25, 0.50, 1.00% one-day-old age. samples analyzed in triplicates. productive traits measured weekly and biochemical indices at end trial. Data st...

an investigation was carried out to evaluate the growth performance of six commercial broiler hybridsavailable in iran (arbor acres, arian, cobb 500, hubbard, lohmann and ross 508). two hundred and fiftyfertile eggs of each hybrid were taken from different breeder farms, all over the country. the similarity offlocks ages and their health conditions were considered. after hatching, the sexed chi...

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...

the effects of phytase and glycosidase supplementation to diets containing rice bran on broiler performance were investigated by using 200 day old (308 ross) broiler chicks in a completely randomized design with five treatments and four replicates. the five dietary treatments were as: corn-soybean meal based diet; diet containing rice bran; diet containing rice bran supplemented with natafous; ...

An experiment was conducted to evaluate the effect of diets with reduced energy level content, supplemented carbohydrase, on broiler performance and coefficient metabolizability nutrients. A total 720 one-day-old male Cobb-500 chicks were distributed in a completely randomized design, six treatments, eight repetitions 15 birds each. The treatments were: (1) positive control, basal diet meet req...

this study was conducted to investigate the effects of different levels of soybean lecithin on performance and blood lipids of broiler chicks. a total of 180 one day old ross 308 broiler chicks were used in a completely randomized design with nine treatments (diets with 0, 0.2, 0.4, 0.6, 0.8, 1, 1.2, 1.4 and 1.6 percent of soybean lecithin) and four replicates for 47 days-rearing period. in ord...

an in vivo experiment was conducted to determine the effect of dietary betaine supplementation (betafin®) as a replacement for methionine on broiler performance and carcass characteristics. in a completely randomized design (crd) with five treatments of betaine levels (at 0, 25, 50, 75, and 100% in replacement for methionine) and five replicates of 10 birds/replicate, two hundred fifty-day-...

This study evaluated the effects of Drinking Thyme Essence (DTE) (Zero, 0.10, 0.15 and 0.20 mL/L) on growth performance, immune response and changing of intestinal bacterial population in broiler chickens. A total number of 500 day old male broiler chicks (Ross 308), were randomly assigned to 4 treatments with 5 replicates and 25 chickens per each, based on a completely randomized design (CRD)....
