Abstract
Feed artificially contaminated with various levels of nalidixic acid-resistant S. montevideo was fed to newly hatched chicks for 7 days. Cloacal and cecal swabs were obtained from the chicks at 7, 14 and 21 days of age to monitor Salmonella colonization relative to the feed contamination level. In 1 of 3 trials, < 1 S. montevideo/g of feed was sufficient to establish colonization in 1-7 day old chicks.
