Broilact® is a refined gut microbiota obtained from a healthy, adult hen. Broilact® colonizes the intestinal surface and establishes a natural, dominant gut microbiota. Used in the hatchery, a single dose provides the flock with lifelong natural defence against undesirable bacteria. With consistent use and proper hygiene management on the farm, the need for antimicrobial treatment is reduced. Broilact® can be used for various species of fowl, including chickens, turkeys, and pheasants.
