Diets contained three levels of Arg relative to Lys (90, 100 and 110%; Arg₉₀, Arg₁₀₀ and Arg₁₁₀, respectively) and a high level of Met (45% dietary Lys).

¹At 34, 36 and 37 days of age, birds were infected with 1 mL (per os directly into the crop) of a culture medium of C. perfringens type A strain 56 containing approximately 10⁸ CFU/mL of bacteria. ^a,b,cMeans within a row with different superscripts differ significantly (P < 0.05).
