Whole lupins are a high-protein, high-fiber legume commonly used in livestock feed for cattle, sheep, horses, and poultry. They are an excellent source of energy and essential amino acids, supporting muscle development and overall animal health. Lupins are also low in starch, making them a great option for animals that require a low-glycemic diet. They can be fed whole or processed and are often included in grain mixes to enhance nutritional value. Additionally, lupins contribute to soil health by fixing nitrogen, making them beneficial in crop rotations.
