Chloramphenicol resistance of Salmonella recovered from the feces (D21, 28, 35, and 42) or intestines (D49) of broilers challenged with Salmonella Typhimurium and fed with and without Diamond V Original XPC^™ at an inclusion rate of 1.25 kg/MT. Dietary treatments, CON (n = 57) or XPC (n = 57), were applied on D21. On D21, 28, 35, 42, and 49, approximately 20% Salmonella recovered from broiler chickens were assessed for resistance to chloramphenicol at the breakpoint concentration (32 μg/mL; CLSI, 2011). Data represent the Mean ± SEM for 3 experiments performed separately. ^a,bP < 0.01
