Suggested Daily Nutrient Requirements

The National Research Council,[1] a committee of poultry nutritionists, has published suggested daily requirements for commercial layers and broiler feeder hens (Table 1). The requirements for the commercial layers are reported as a percentage of the diet when the hen consumed 100 grams of feed. For this article, the requirements have been changed to the daily intake. This makes it possible to compare the requirements of hens that are used for two different purposes. All of the requirements are higher for the broiler breeder hen than for the commercial egg layer.

The laying hen does not have a requirement for crude protein per se. She needs 22 amino acids, but requires specific amounts of the 10 listed in Table 1 to be present in the feed. However, there should be sufficient crude protein in the feed to ensure an adequate supply of nonessential amino acids.
