FIGURE 1.

Experimental design. Piglets (n=8/treatment) were weaned from their sow and offered nursery diets containing either 0% SDP, 2.5% Spray dried plasma (SDP) for 1 week post-weaning (PW), or 5% SDP for 2 weeks PW. SDP was removed from experimental diets at indicated times and fed identical diets to controls. At 34 d PW, pigs were challenged with S. Typhimurium. At 2 d post challenge, tissues were harvested for analysis. P-1 = Phase 1 diet; P-2 = Phase 2 diet.
