In animal science, these are feedstuffs low in fiber and high in energy and/or protein. Cereal grains, oil meals, and by-product feeds exemplify this category. For instance, corn, soybean meal, and distillers grains provide a concentrated source of nutrients crucial for animal growth and production.
The strategic use of these feed components is vital for optimizing animal performance, particularly in intensive production systems. Their inclusion allows for increased energy intake and improved nutrient density in diets, supporting enhanced growth rates, milk production, and reproductive efficiency. Historically, their utilization has evolved alongside advancements in animal nutrition and agricultural practices, leading to more efficient and sustainable livestock production.
