The poultry industry has been progressively phasing out prophylactic use of antibiotics in broiler chicken pro-duction thereby mandating the industry to contend with less reliance on the use of antibiotics. Under current Canadian regulations, the majority of commercial broiler chickens are reared on one of three gut health management programs: 1) conventional (CON), where some medically important antibiotics (MIA) are allowed, 2) raised without medically im-portant antimicrobials (RWMIA), and 3) raised without antibiotics (RWA).
