Standard commercial practice is to deny poultry access to feed 8 to 12 h prior to slaughter. Occasionally a flock of turkeys is marketed at several ages, and starvation can occur for birds that are not shipped. For this project multiple marketed female turkeys were fed a special diet (nutritive supplement) during the preslaughter feed withdrawal period to reduce live weight loss, bird stress, a...

AIMS To determine the effect of antimicrobial selective pressure on the transmission of antimicrobial resistant and sensitive strains of Salmonella in poultry. METHODS AND RESULTS Eight pens housed 12 broiler chicks each. Two chicks in four of the pens were inoculated with a Salm. Typhimurium strain resistant to 12 antimicrobials (including tetracycline), and two chicks in each of the four ot...

Community acquired multidrug resistant E. coli has become an emerging issue worldwide. The present study was planned to compare the antibiotic resistance profile of E. coli isolated from commercial broilers and backyard poultry reared in close proximity to human population. Out of 200 cloacal swabs (100 each from commercial broiler & backyard poultry), 126 samples (n=70 commercial broiler, n=56...

Any deficiency in trace element content of commercial poultry diets will decrease their performance. To prevent this situation it is necessary to supplement trace minerals in poultry diets to allow the modern birds to reach their genetic potential. The NRC publication as the most famous reference for livestock and poultry nutrients requirement has no recommendation for some less needed trace mi...

Ongoing economic losses by and exposure of humans to highly pathogenic avian influenza (HPAI) in poultry flocks across Asia and parts of Africa and Europe motivate also outbreak-free countries such as Switzerland to invest in preparedness planning. Country-specific population data on between-farm contacts are required to anticipate probable patterns of pathogen spread. Information is scarce; in...

Poultry fat has become a more economical source of energy than byproducts currently used. Therefore, this study was conducted to determine the effects of dietary fat source (poultry fat or beef tallow) in finishing diets for cattle on the fatty acid composition of beef. Sixty Angus crossbred steers (410.8 kg initial BW) were stratified by source, blocked by weight, and assigned within block to ...

The risk for influenza A(H5N1) virus infection is unclear among poultry workers in countries where the virus is endemic. To assess H5N1 seroprevalence and seroconversion among workers at live bird markets (LBMs) in Bangladesh, we followed a cohort of workers from 12 LBMs with existing avian influenza surveillance. Serum samples from workers were tested for H5N1 antibodies at the end of the stud...

In recent years the economic damage inflicted by several avian influenza (AI) subtypes (primarily H5N1 and H9N2, but also H7N1, H7N3, H7N7) on the commercial poultry industry and backyard poultry is beyond simple calculation. In response to the continued losses suffered by commercial poultry producers large scale vaccination has been introduced in many affected countries for the commercial sect...
