Background: This study was conducted to analyse the effect of different enzymes and selenium on production performance slaughter parameters Ross (308) broilers production. Method: There were four groups in this experiment, two them control test groups. All had same number one-day-old chickens (20250), moved day. 100 selected randomly for future analyses. The group fed with standard commercial d...

The aim of the present study was to compare carcass characteristics and meat quality fast- (Ross 308), medium- (Hubbard JA757) slow-growing (ISA Dual) chickens (n = 1 980). When reached an average live weight 2 kg, 40 birds (males females, : 1) each genotype were randomly selected slaughtered for analysis. Pectoralis major (PM) muscle samples taken determine physical chemical parameters quality...

this study was conducted to investigate the effect of different levels of savory (satureja hortensis) powder and its essential oil on performance and antioxidant status of broiler chickens under heat stress (34±2 ˚c for 8 hours per day). a total of 336 one-day-old male broiler chicks (ross-308) were divided into 6 treatments and 4 replications (14 birds per replicate). experimental diets were a...

in order to evaluate the effect of polyunsaturated fatty acids on ascites incidence using this experiment was conducted 136 male one day (chicken ross 308) in a completely randomized design with 2 treatments and 4 replication and 17 chickens in each replicate. treatments includes: diet contain 4 % soybean oil (n3:n6:0.112) and diet include 5.5% poultry oil (n3:n6:0.201). birds were raised up to...

This paper discusses the outcomes of production experiment carried out on one poultry farms in Sverdlovsk Region and at departments Ural State Agricultural University. The was cross Ross-308 broiler chickens number 80 female male with an average live weight 43 g. During research, were housed different cages; continued throughout entire rearing period - 38 days. control group formed comparable f...

The presented research was carried out to investigate hematological response low dose gamma radiation in chickens hatched from irradiated eggs. A total of 700 Ross-308 eggs were divided into the experimental group (N=360) and control (N=340). one hour before incubation with a cobalt-60 (60Co) panoramic irradiator, sham irradiated. Blood samples for red blood cell (RBC) white (WBC) counts differ...

The current study evaluated the effect of a commercial wheat-maizesoybean meal based diet supplemented with an organic acid product containing a specific combination of formic and propionic acids (pHorce) on performance parameters in broiler chickens. One day-old broiler chickens (Ross 308) were randomly allotted to 2 treatments with 10 replicate cages/treatment and 2 birds/cage from d 1 to 21....

Five experimental groups were used to evaluate the efficiency of sodium bentonite (BNT) and ascorbic acid (AA) in reducing the toxicity of aflatoxin B1 in ElSalam chicks (Egyptian local chicks) diets. A total number of 450 unsexed one-day old chicks were wing banded, weighted and randomly assigned to 5 groups of five replicates (18 chicks/replicate). The experimental groups were as follow: 1) b...

In the present experiment, 320 one day old Ross 308 broiler chickens were used completely randomized design with 4 treatments, 4 replicates, and each replicate contained 20 broiler chickens. Experimental treatments include control, 0.5, 1, and 2% of Thymolina powder in chickens’ diet. Thymolina is an antibacterial powder drug which is made by composing 4 medicinal plants. A significant differen...

This study was conducted to examine the effect of natural compounds, such as β-glucan, carotenoids, oligosaccharides, and anthocyanins in diet on bacteria gropus excreta Ross 308 broiler chickens. Chickens were fed 5 diets: control (basal) diet, a supplemented by β-glucan at 0.05%, diets or 0.5% each compound. On experimental day 19, collected determine proportion Lactobacillus, Bifidobacterium...
