Which two feed ingredients are most common in poultry diets in the U.S.?

The most common feed ingredients in poultry diets in the U.S. are corn and soybean meal. Corn is widely used due to its high energy content, making it an excellent source of carbohydrates for poultry. It provides the necessary calories for growth, maintenance, and production in birds. Soybean meal is a key protein source in poultry diets, rich in amino acids that are vital for muscle growth and overall health. Together, corn and soybean meal create a balanced diet that supports the nutritional needs of poultry, promoting optimal health and productivity.

The other options, while they may have some presence in poultry diets, do not match the prevalence and nutritional suitability that corn and soybean meal provide for modern poultry farming in the U.S.
