Title: Precision poultry nutrition and feed formulation
Abstract: The production of poultry products with minimal negative impact on the world's environment is critical to sustainability of one of our most important sources of high quality animal protein. With respect to poultry nutrition, maximizing nutrient bioavailability of the diets and formulating those diets to precisely meet the bird's growth requirements at any given time is perhaps one of the most important aspects of environmental, social and economic sustainability. This chapter explores the evolution of the National Research Council's Nutrient Requirements of Poultry through the most recent 1994 edition. Today's modern breeds of production poultry are genetically much different than they were half a century ago and their diets have changed correspondently. During the 1940's we fed just a few different diets to poultry, primarily a grower diet and a layer diet with similar concentrations of dietary protein and energy. Today we feed both broilers and laying hens many different diets throughout their respective production periods in an attempt to be as precise as possible at meeting the optimal nutrient requirements for growth and reproduction without overfeeding and negatively affecting the environment. The availability of crystalline amino acids, growth promoters, probiotics, prebiotics, effective exogenous enzyme products, and new ideas on formulating diets with optimal amounts and proportions of proteinogenic amino acids have all contributed to the goal of sustainable poultry production with minimum environmental impact.
