^aGlutamine per kg standard diet feed: Con, 0% Gln, noninfect control treatment; 0.5%Gln = basal diet supplemented with 0.5% Gln; 1.0%Gln = basal diet supplemented with 1.0% Gln. Scc = Salmonella pullorum infect control treatment received the basal diet
^bADG Average daily weight gain, ADFI Average daily feed intake, FCR Feed conversion ratio
^cThe P-values represent the main effect of the diet, the main effect of Salmonella pullorum challenge, and the interaction between the dietary treatments and Salmonella pullorum challenge
