Enzyme additives can improve digestion in broiler chickens


Dr. Jason Lee compares the enzyme additives he’s testing in chicken broiler feed to the probiotics now commonly added to human food, such as yogurt.

Like probiotics, the enzymes he’s testing improve digestibility of the food the chicken eats, acting within the gut, said Lee, who is a poultry scientist with Texas A&M AgriLife Research at College Station.

“And like probiotics, the enzymes naturally occur in nature,” he said.

The analogy is imperfect, he said, as the probiotics added to yogurt and other foods to aid digestion are live bacteria, while enzymes are not alive at all, but merely simple proteins.
