Grinding corn to a finer particle size has been shown to have beneficial effects on growth, feed efficiency, and digestibility. The trial demonstrated improvements in growth and efficiency. However, in contrast to previous research, pelleting did not result in an improvement in growth and feed efficiency. Using this model, we were unable to detect influences of feed processing on fecal shedding and colonization of mesenteric lymph nodes with salmonella. Therefore, it appears that the increased risk of finer grinding and pelleting of feeds associated with salmonella shedding reported in other studies may be due to factors other than those confined to the intestinal tract environment.
