Nutrient Requirements of Poultry: 10th Revised Edition


Meeting #1 - 07/16/17
Meeting 5: Nutrient Requirements of Poultry, 10th Revised Edition - 12/09/17

Statement of Task

The committee will prepare a report that reviews the scientific literature on the nutrition of poultry and make recommendations on nutrient requirements. All life phases and types of production will be addressed. New recommendations will be made with consideration for the increased performance of different types of poultry, including broilers, turkeys, laying hens, and ducks with updates to additional species, as appropriate.

The report will include a comprehensive analysis of recent research on feeding and nutrition of poultry including new research on the amounts of energy, amino acids, lipids, minerals, vitamins, and water needed by poultry; a summary of the composition of feed ingredients, mineral supplements, and feed additives routinely fed to poultry; information about variability in feed ingredients sourced from different regions; and, information about feed ingredients from the biofuels industry and other new ingredients (e.g., novel soybean products).

The report will examine requirements for digestible phosphorus and amino acids and update concentrations of digestible phosphorus and amino acids in feed ingredients, examine new information about nutrient metabolism and utilization and provide a review of nutritional and feeding strategies to minimize nutrient excretion.

A discussion of the effect of feeding on the nutritional quality of poultry meat and eggs will be included. Effects of the environment, feed management, and other production aspects on nutrient requirements, including antibiotics and their alternatives, will be addressed. In addition, quantitative information on requirements will be incorporated, as well as new information on bioavailability of various nutrients.

The report also will include mathematical equations that reflect the biologic basis for predicting requirements and performance based on nutrient input-production response relationships. Depending on the extent of new information available, a computer model may be developed that incorporates these mathematical equations. Future areas of needed research also will be identified.
