To study the effects of terbutaline (a beta adrenergic agonist) on performance of broiler chickens, 21 d-old male and female Cobb broiler chicks (n=300) were randomly assigned to one of five dietary treatments containing 0 (control), 5, 10, 15 and 20 mg terbutaline per kg diet. The feed conversion ratio (FCR), feed intake and body weight gain were measuered after 3 weeks. At 42-d age, six males...
This study was conducted to compare the effects of diets Borage Powder and control (no additives diets) on broiler’s average blood cell counts and immune system on the broiler chicks. Sixty four male broiler chicks (Ross 308) randomly allocated into one of two treatments with four replicates of eight chickens based on a completely randomized block design. Diets were include control (no additiv...
This study was designed to investigate the effects of different levels of Tarragon powder on general performance and Anetometric, properties of digestive system of male broiler chickens. 200 one-day-old Ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. Experimental diets were set...
OBJECTIVES This study investigated the prevalence of vancomycin-resistant enterococci (VRE) in the broiler production environment after the avoparcin ban and their epidemiological relationship with human clinical VRE from the same geographical regions in Greece. METHODS Caecal contents from broilers (n = 500) from eight livestock farms and faecal samples from poultry slaughterers (n = 50), al...
