Introduction

Because synthetic amino acids are generally banned in organic livestock production, and animal slaughter by-products cannot be used in organic feed, nutrition can present challenges in organic poultry production. Providing the amino acid methionine (MET) is generally the most difficult one. Feed rations that are high in plant proteins, such as soybean meal, can be used instead of synthetic MET, but high protein diets are not healthy for poultry or the environment. Diets containing fishmeal, milk products, and nonconventional sources of protein, such as earthworms or insects, can help provide MET, but the ingredients are expensive and, in most cases, not available in organic form. It is difficult to design diets with sufficient MET without oversupplying protein. For these reasons, development of a natural MET supplement is needed.
