Figure 3From: Increased arginine, lysine, and methionine levels can improve the performance, gut integrity and immune status of turkeys but the effect is interactive and depends on challenge conditionsPercentages of splenic T (CD4+, CD4+CD8α+, CD8α+) and B (IgM+) cell subpopulations in turkeys fed high or low dietary arginine, lysine and methionine levels (left side of the figure) and as a result of either C. perfringens infection, E. coli LPS challenge or no challenge (right side of the figure). a,b,cMeans within a row with different superscripts differ significantly (P < 0.05).Back to article page
