This experiment was conducted to investigate the effects of olive leaf (OL) on immune response and some blood metabolites of broiler chickens. A total of 400 one-day-old broiler chicks (male and female) were randomly assigned to 5 experimental treatments with 4 replicates of 20 birds each. Birds of different treatments were given diets containing 0, 0.25, 0.5, 0.75 and 1% OL powder from 14 to 4...
This study evaluated the efficacy of aqueous extract of Thymus daenensis to ameliorate the adverse effects of aflatoxin B1 (AFB1) in Japanese quail. The experiment was conducted as a 2×2 factorial arrangement in a completely randomized design with two levels of aflatoxin (0 and 500µg/kg) and two levels of aqueous extract of T. daenensis (0 and 2000 mg/kg). Each of the 4 dietary treatments was f...
Differences among eight commercial broiler strains in factors indicating susceptibility to ascites were investigated. Chicks from eight crosses were obtained from two hatcheries (one was obtained from both hatcheries to give a total of nine) and raised to 6 wk of age on commercially prepared rations containing 3,300 kcal/kg energy with 24% protein to 3 wk of age and 20% protein from 3 to 6 wk. ...

A comparison of two types of scalders was conducted to determine their effectiveness in reducing bacterial contamination of poultry carcasses. A conventional hot-water scalder and a prototype model of a steam scalder were tested under commercial conditions. Total plate counts from steam-scalded birds were significantly lower than the counts of water-scalded birds immediately after scalding and ...
the present study was done to study the effects of water hypericum perforatum extract (whpe) on performance, abdominal fat, carcass characteristics, and blood biochemical parameters of broilers with 160 day-old ross 308. broilers were randomly distributed among the16 experimental units of four treatments with four replications (10 birds in each replicate) for 42 days. the treatments were includ...

To evaluate the effect of broiler growth rate and feed intake on development of the inflammatory response‚ commercial broiler diets were fed to 275 day–old chicks of the modern 2000 strain and 1957 random-bred strain. Half of the chicks had free access to feed while others were restricted. Twelve birds from each strain and group pens were removed‚ weighed, and housed in individual cages by thei...
Background and Objectives: The heavy metals pollution in aquatic ecosystems especially mercury, always makes concern about health of aquatic organisms. So, the purposes of this study were determination of total mercury in different tissues of the three species of the most important water birds at north of Iran and comparison with world health standards.Materials and Methods: Generally, 51 birds...
