Which crop is known for producing a common food oil and high protein meal used for livestock feed?

The reason soybean is recognized for producing a common food oil and high protein meal used for livestock feed is due to its unique composition. Soybeans are approximately 20% oil and 40% protein, making them a valuable crop in both human diets and animal nutrition. The oil extracted from soybeans is widely used in cooking and food processing, while the remaining meal, which is rich in protein, serves as an important component in livestock feed. This dual purpose enhances the crop's economic significance in agriculture.

In contrast, while alfalfa is primarily grown as a forage crop for livestock, it does not produce oil or high-protein meal. Corn is important for its carbohydrate content and can also provide some oil, but it is not known for high protein content like soybeans. Wheat is mainly cultivated for its grain, which is a staple food source and not typically associated with high-protein meal production used in livestock feed. Thus, soybeans stand out due to their multifaceted contributions to both food oil production and high-quality animal feed.
