Exact Nutrition in Poultry: Beyond Conventional Nutrient Requirements to Intelligent Feeding Initiatives to Enhance Performance and Gut Health: A Review

Precision nutrition is an advanced way of feeding chicken with a more accurate ratio of nutrients content with the real requirements of poultry in the production cycle. Precision nutrition tries to improve the utilization of nutrients by refining nutrient use by a more adaptable feeding system, including refined phase feeding, diet mixing, the inclusion of functional feed additives, unlike the more conventional feeding systems by which various dietary phases are pursued. This has increasingly become of interest in view of its capacity to enhance growth rates, facilitate gut operations and reduce the amount of nutrients that are excreted. Besides, accuracy nutrition is accompanied by intestinal functionality, microbial balance, and feed efficiency as essential factors of modern poultry growth. Therefore, the substitution of conventional feeding, which is characterized by the usage of nutrients, with intelligent feeding systems can result in more efficient and sustainable as well as healthy poultry production. The review includes the concept of precision nutrition in poultry, its interaction with the traditional models of feeding, and the primary strategies of smart feeding, as well as its implications on the growth performance and the health of the gut.
