seventy poultry farms’ drinking water was tested for escherichia coli contamination in qom province iniran. the cases of colibacillosis from positive farms were also collected and tested. the isolates wereexamined for serotype, detection of virulence genes by multiplex pcr and antibiotic resistance. thirtypoultry farm water samples were e. coli positive (18.57%), although 13 e. coli isolates we...

This study investigated the effects of light sources and light intensity on growth performance, carcass characteristics, and welfare indices of heavy broilers (>3.0 kg) in 4 trials with 2 replications per trial. A total of 960 one-day-old Ross×Ross 708 chicks (30 males/30 females/room) were randomly distributed into 16 environmentally controlled rooms at 50% RH. A 4×2 factorial treatment struct...

Outdoor access is an important part of organic and free-range poultry production, yet limited information exists on the effect of various housing and production systems on growth performance and colonization of food-borne pathogens. Therefore, the primary purpose of the current study was to evaluate the influence of different housing systems, particularly fixed versus small, portable houses, wi...

Incidents of foodborne illness associated with consuming undercooked or raw chicken are often linked to 2 causative pathogens: Campylobacter spp. or Salmonella spp. Numerous studies have shown that contamination of carcasses results when pathogens are transferred from the intestinal tract or fecal material on feet and feathers to the dressed carcass. Ultraviolet spectral imaging to detect surfa...

Antibiotics have been common feed additives in poultry rations as growth promoters to improve performance via reducing burden of pathogens. However, it has been increasing pressure to reduce or even eliminate antibiotic usage in poultry feed due to the negative human health issues of antibiotic resistance. Safe broiler production without medication and vaccination was conducted at present study...
