Single cell protein (SCP) is the definition for dried cells originated from single-celled organisms intended to be used as a protein source in human foods or animal feeds. An experiment has been conducted to evaluate the various levels of single cell protein on fecal microflora and productive traits of broiler chickens. A total of 192 day-old Ross 308 male chicks were randomly divided into 4 tr...

this experiment was conducted to evaluate the effects of different levels of zinc on the performance and humoral immunity response in broiler chickens with 250 ross broiler chickens with five experimental treatments consisted of five replicates in a completely randomized design. treatments were diets containing: basal diet (control) and basal diet plus 40, 80, 120 and 160 mg zn/kg. results of t...

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 ...

the aim of this study was to recognize the effects of dietary hempseed (hs) and hempseed oil (ho) on performance, egg quality and blood parameters of laying hens. a total of 320 hy-line 55-weeks laying hens were randomly allotted to eight dietary treatments with five replicates (8 birds each). the experimental treatments were offered as a completely randomized design as follow: control group (n...

This study aimed to investigate the effects of adding pumpkin (PK) and garden cress (GC) seed oils laying diets, as nutraceuticals, on physiological productive performance layers. A total 360 hens, at 24 weeks age, were randomly equally assigned into four groups nine replicates each (10 birds/replicate). The 1st group was fed basal diet served a control. 2nd, 3rd, 4th diets supplemented with 0....

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...

This study was conducted to investigate the effect of feed particle size and feed form on growth performance, nutrient metabolizability and intestinal morphology in broiler chickens. This experiment was a 2×2 factorial arrangement including two feed particle sizes (fine and coarse) and two feed forms (mash and pellet). A total of two hundred and eighty eight day-old male Arbor Acre broilers wer...

The effects of dietary supplemental guanidinoacetic acid (GAA) on performance, biochemical indices and meat pH of broilers with cold-induced ascites were studied. A total of 640 day-old male broiler chicks (Cobb 500) were assigned to four dietary treatments including control diet; control diet supplemented with either 0.6, 1.2 or 1.8 g of GAA per kg of feed. Each treatment was replicated in 8 b...

The aim of the present study was to evaluate the effect of commercial monostrain and multistrain probiotics in diets on growth performance, intestinal morphology and mucin gene (MUC2) expression in broiler chicks. Three hundred seventy-eight 1-d-old male Arian broiler chicks were allocated in 3 experimental groups for 6 wk. The birds were fed on a corn-soybean based diet and depending on the ad...

this experiment was conducted to investigate the effect of synbiotic and two levels of dried garlic powder on performance during 1-49 and ileum morphology and microbial population at 49d of age in broiler chicks. the experiment was conducted in a completely randomized design with 5 treatments, 4 replicates of 10 chicks per replicate. the dietary treatments consisted of 1) control diet without a...
