What is a typical energy source in finishing diets for beef cattle?

In finishing diets for beef cattle, corn and soybean meal are typical energy sources due to their high energy content and digestibility. Corn is particularly favored as it provides a concentrated source of carbohydrates that can efficiently meet the energy needs of cattle, promoting rapid weight gain and optimal feed conversion efficiency. Soybean meal complements corn in these diets, serving as a high protein supplement that supports muscle development and overall growth.

In contrast, while other options present some viable ingredients, they do not match the specific energy density and nutritional profile of corn and soybean meal. For instance, grass and hay tend to be lower in energy and are more commonly utilized in earlier stages of production or as forage rather than in finishing diets. Silage and oats can add energy, but they are generally not as concentrated or effective as corn. Likewise, wheat and barley might be used in certain circumstances, but corn remains a preferred grain for its balance of energy and cost-effectiveness. Therefore, corn and soybean meal emerge as the predominant choice for energy sources in finishing diets for beef cattle.
