Apparent attachment of Campylobacter and Salmonella to broiler breeder rooster spermatozoa.
It has been demonstrated that horizontal and vertical transmission of Salmonella and Campylobacter can occur in broiler breeder flocks. The mechanism of this transmission is still unclear. Previously negative broiler breeder flocks have been reported to become positive with Salmonella, Campylobacter, or both after the introduction of "spike" roosters at 45 wk of age. To determine whether the ro...
متن کاملImproved Efficiency of Intact Crop Removal for Broiler Breeder Rooster and Hen Carcasses During Manual Evisceration
By using a technique that previously demonstrated improved efficiency of intact crop removal for broilers, experiments were conducted to determine the effectiveness of the technique in 40and 41-wk-old broiler breeder roosters and hens. The technique involved (after scalding, defeathering, and head removal) separating (breaking) the neck from the carcass parallel with the shoulders and leaving t...
متن کاملPresence of naturally occurring Campylobacter and Salmonella in the mature and immature ovarian follicles of late-life broiler breeder hens.
Campylobacter and Salmonella are known to cause acute bacterial gastroenteritis in humans. Raw poultry products have been implicated as a significant source of these infections. Five trials were conducted to determine whether Campylobacter and Salmonella spp. exist naturally in the mature and immature ovarian follicles of late-life broiler breeder hens. Broiler breeder hens ranging from 60 to 6...
متن کاملDistribution and Genetic Profiles of Campylobacter in Commercial Broiler Production from Breeder to Slaughter in Thailand
Poultry and poultry products are commonly considered as the major vehicle of Campylobacter infection in humans worldwide. To reduce the number of human cases, the epidemiology of Campylobacter in poultry must be better understood. Therefore, the objective of the present study was to determine the distribution and genetic relatedness of Campylobacter in the Thai chicken production industry. Duri...
متن کاملCampylobacter and Salmonella infections on organic broiler farms
Organic poultry production in the Netherlands is developing. Although consumers assume organic products to be safer and healthier, there are aspects of organic animal husbandry, like access to an outdoor run, that can result in increased risks of food safety problems. The aim of this study was to compare housing and management of organic and conventional broiler farms in the Netherlands and to ...
