Figure 3.

Salmonella typhimurium translocation to the mesenteric lymph nodes (MLN) and spleen in pigs fed high-fiber diets (HF; 20% total dietary fiber) or low-fiber diets (LF; 13% total dietary fiber) with standard threonine (STD Thr; 0.65% SID) or supplemental threonine (SUP Thr; 0.78% SID). Data presented as mean scores. A shedding score of 3 was assigned to plates positive for the inoculated S. typhimurium with counts > 30 and plates positive but with counts < 30 were given shedding score of 2. A shedding score of 1 was assigned to plates that were only positive after enrichment and plates negative after enrichment were scored zero. No significant (P > 0.05) fiber, threonine, or interactive effects on S. typhimurium shedding in either MLN or spleen.
