SUMMARY The use of exogenous feed enzymes in poultry diets is becoming a norm to overcome the adverse effects of antinutritional factors and improve digestion of dietary components and bird performance. In this paper, an overview of the science behind the use of feed enzymes and the current status of enzyme technology is provided. Responses to enzyme supplementation are often variable and the reasons contributing to the observed variability are discussed. Though there are opportunities to enhance nutrient utilization with enzyme supplementation, there will be physiological limits to achievable responses. These limits are imposed by the pH and digesta retention time within the digestive tract. Nutritional strategies to, at least partly, overcome these limits need to be explored; potential approaches include feeding to restore functionality of crop and gizzard as well as the use of unconventionally high doses of enzymes. Anticipated future development of better forms of feed enzymes will also lower the physiological barriers.

- Exogenous Enzymes as Zootechnical Additives in Animal Feed: A Review (2021, background): “The effects of the action of enzymes used in animal feed processing have not been fully clarified; however, their success can be attributed to any of the following mechanisms [3,4,11].”
- Achieving sustainable aquaculture: Historical and current perspectives and future needs and challenges (2020, background): “The use of enzymes as feed additives has been relatively commonplace in the terrestrial animal feed sector for some time, but is definitely less established in the aquafeed sector (Bedford, 1995; Castillo & Gatlin III, 2015; Ravindran, 2013).”
