As organic poultry commands larger shares of markets, consumers, producers, and regulatory agencies seek ways to provide dietary methionine, required in production of essential protein for growth. Poultry producers continue to advocate for the use of synthetic methionine in traditional and organic poultry diets as alternative sources of this amino acid are not yet readily available at low cost. Raising broilers on organic pasture or raising slow-growing broiler genotypes with choice feeding are alternatives for niche markets. Other possibilities of methionine-rich feed ingredients for fast growing broilers include algae, probiotics, insects at various stages of development, fishmeal, poultry byproduct meal, pea protein, rapeseed, rapeseed expeller, rice protein, various types of beans/peas, and sunflower seed meal. Two of these possible poultry feed ingredients, cowpeas and sunflower seed meal, are presently available for use on a large commercial scale. These feed ingredients are grown in many parts of the world. Feed formulation show that they, along with reduced amounts of soy and corn, can be used to create organic starter, grower, starter, and finisher diets without added methionine.
