Aim of the study was to evaluate effects diet non-phytate phosphorus (P) and calcium (Ca) level on growth performance some blood, bone faeces parameters broilers. A total 480 one-day-old Ross 308 broilers were randomly allocated 3 dietary treatments with 5 replicates for a 42-d study. Corn-soybean meal based diets consisted three different Ca P concentrations starter grower periods. High, mediu...

this study was conducted to investigate the effect of dietary soy isoflavones (isfs) on growth performance, blood parameters and tibia ca and p content of broiler chickens. a total of 240 as-hatched day-old ross 308 chicks were used in a completely randomize design with four treatments (0 (control), 25, 50 and 100 mg/kg of isf), three replicates and 20 birds per each replicate for a period of 4...

this experiment was conducted to evaluate the effect of different dietary enzyme supplemented non-starch polysaccharides on growth and physiological traits of broilers. 625 one day old ross-308 broiler chickens were allocated randomly to 5 treatments with 5 replicates using a crd statistical design through 1 to 21 and 22 to 42 days of rearing period. treatments were included control, wheat, whe...

introduction & aim: the aim the present study is to examine the effects of boswellia serrata triana & planch on (immune response) performance and carcass characteristic in broiler chicks.  experimental: in this study, 360 one day old chicks (ross 308) were allocated to six treatments with four replicates in a completely randomized design for a six week period. treatments consisted of t...

effect of globacid® acidifier in different stocking densities on performance and blood metabolites was examined using 576 one-day broiler chickens ross 308 in a completely randomized design with 6 treatments and four replications for each treatment through a (3 × 2) factorial arrangement with three levels of stocking densities (14, 16 and 18 chicks per square meter) and two levels of globacid® ...

this experiment was conducted to evaluate the effects of dietary salvia mirzayanii supplementation on performance, carcass characteristics, internal organs and cecal microbial population in broilers. a total of 200, one-day-old broiler chicks (ross 308) were fed five experimental diets containing different levels of s. mirzayanii (zero, 0.25, 0.50, 0.75 and one percent of diet) until 42 days of...

in order to evaluate the effect of feeding different levels of vermi-humus supplement (as a source of humic acid) on the performance of broiler chickens an experiment was conducted using 240 broiler chickens (ross 308) in a completely randomized design by four treatments (vermi-humus levels of 0, 0.5, 1 and 1.5 percent) and five replicates of 12 chickens per each for 42 day. the experimental tr...

in order to evaluation the effect of nigella sativa supplementation on performance, immune response and some of blood parameters, a total of 192 one day old ross 308 broilers were used in a completely randomize design with four treatments, four replicates and 12 observations in each replicate. treatments included the increasing levels of zero (control), 0.4, 0.8 and 1.2 percent nigella sativa. ...

This research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. For that, 312 day-old male Ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. Chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. Diets include...

The current study was conducted to evaluate effects of sequential or wet feeding programs subsequent to and early meal feeding regime on performance, carcass characteristics and humoral immunity in broiler chicks. 192 Ross 308 chicks (seven-day old) were allocated to four treatments at four replicates (12 chicks per plot) based on a Completely Randomized Design. Treatments were included: contro...
