A study of Salmonella contamination in broiler flocks.

The study was designed to follow the Salmonella infection rate in a poultry flock during the growth period until processing at 8-9 weeks. The infection rate was as high as 37.5% initially and dropped significantly by the 3rd to the 5th weeks. There was no difference between various types of litter and the species of Salmonella isolated. Little correlation was found between Salmonella species in feed ingredients and those identified from the flocks.
