Background and Objectives: Salmonella contamination of broiler breeder farms is of great importance regarding transmission of the bacteria through the production chain of poultry meat. The aim of this study was to determine the prevalence and management related factors of Salmonella contamination in broiler breeder flocks in Iran. Methods: This cross sectional study was carried out between 2...
The aim of the current experiment was to evaluate possibility use gyttja as an alternative litter material pine wood shaving in broiler production. In 3150 chicks were used two experimental groups consisting 1575 with three repetitions (3x525 chicks). last for 39 days. During same diets. There no significant differences between terms live weigth, feed consumption, conversion ratio and mortality...
Workers are exposed to dust in broiler chicken production during daily work activities. Poultry dust may contain inflammatory agents (e.g., endotoxin) and inhalation exposure has been associated with pulmonary symptoms. Current practice to reduce worker exposure to poultry dust is the use of respiratory protection (e.g., elastomeric face-piece respirator with a P100 and ammonia chemical cartrid...
The CO2 production rates from various animal species were measured as well as the ventilation rates (VR) in environmental rooms at Michigan State University over the course of 15 studies that considered dietary strategies to alter air emissions, including two dairy cow studies, four steer studies, two swine studies, one turkey study, four laying hen studies, and two broiler chicken studies. The...
Comprehensive mitigation strategies for gaseous emissions from broiler operations requires knowledge of the litters' physical and chemical properties, gas evolution, bird effects, as well as broiler house management and structure. This research estimated broiler litter surface fluxes for ammonia (NH3), nitrous oxide (N2O), and carbon dioxide (CO2). Ancillary measurements of litter temperature, ...
Salmonella enterica ssp. enterica is a leading cause of bacterial food-borne disease outbreaks worldwide and is also an economic burden particularly in Reunion Island because its population consumes large amounts of chicken and cooks 100% chicken sausages (35 kg per capita per year). The aim of this study was to investigate the epidemiology of Salmonella Typhimurium and Salmonella 1,4,[5],12:i:...
MIC-tests in replicate were performed on 286 Salmonella isolates (269 from Danish poultry, including 256 from broiler houses, and 17 from England, mainly from poultry) against five disinfectants used in the poultry industry (glutaraldehyde/benzalkonium chloride compound, formaldehyde, oxidising compound, tar oil phenol, iodophor). Generally, the small variations in MIC could not be associated w...
