Piling behavior (PB) is a common issue that causes negative impacts on the health, welfare, and productivity of flock in poultry houses (e.g., cage-free layer, breeder, broiler). Birds pile top each other, weight birds can cause physical injuries, such as bruising or suffocation, may even result death. In addition, PB stress anxiety birds, leading to reduced immune function increased susceptibi...

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...

Three commercial broiler houses were (12.2 × 152.4 m) were monitored for 3 consecutive flocks. The houses were treated with Poultry Litter Treatment (PLT), 24 h before bird placement at the rate of 24.4 kg /100 m2. PLT was applied in the central brooding area for all 3 flocks and represented the treated (TR) area while the rest of the house remained untreated (UN). Litter samples were obtained ...

Genetic diversity at the MHC and non-MHC loci was investigated in three commercial broiler chicken pure lines. The MHC class II and IV loci were evaluated in Southern hybridizations and molecular genotypes based on RFLP were interpreted from pedigreed families. Four MHC class II and eight class IV genotypes were identified in the broiler lines, and their frequencies differed among the lines. Li...

Ornithobacteriosis is an infectious disease of avian species that has been reported in almost all countries around the world, except Thailand. The objectives of this study were to determine the seroprevalence of Ornithobacterium rhinotracheale (ORT) and to isolate and identify ORT in broilers and broiler breeders in Thailand. Chicken antibodies had been randomly checked from 17 farms (19 flocks...

BACKGROUND The concurrent rise in consumption of fresh chicken meat and human campylobacteriosis in the late 1990's in Iceland led to a longitudinal study of the poultry industry to identify the means to decrease the frequency of broiler flock colonization with Campylobacter. Because horizontal transmission from the environment is thought to be the most likely source of Campylobacter to broiler...

The effects of UV irradiation at a wavelength of 254 nm on the survival of Campylobacter jejuni on the surfaces of broiler meat, skin, and carcasses were studied. On broiler carcasses, the effects of UV were also studied in combination with activated oxygen. The surfaces were inoculated with varying counts of C. jejuni and treated with UV irradiation using doses ranging between 9.4 and 32.9 mW/...

Chicken meat is an important source of foodborne pathogens, including Salmonella, Campylobacter, and Clostridium perfringens. These bacteria can occur in the intestinal microbiota broilers contaminate chicken carcasses industrial processing. This study aimed to develop evaluate a procedure based on real-time PCRs for direct detection quantification these three broilers’ ceca collected poultry s...

Improved methods for broiler chicken (Gallus gallus domesticus) litter utilization are needed to alleviate potential impacts of pollution around broiler production operations. Pelletization may constitute one improved method for handling broiler litter. The objective of this study was to determine the change in nutrient concentration from pelletizing broiler litter, and determine availability o...
