Palm meal is a by-product of palm kernel dehulling and oil extraction. Its shape and color are similar to rapeseed meal, with a slight chocolate odor. The quality of palm kernel meal varies greatly depending on its degree of dehulling and processing technology (similar to cotton meal technology). The direct manifestation of using palm kernel meal to replace some corn is that the feeding effect remains unchanged, but the feed cost is significantly reduced, and the competitiveness of animal products in the industry is significantly improved. And it is about 400 yuan cheaper than corn per ton. With the rapid increase in corn prices in the northern and northern regions of China, and the long-term low prices of livestock products, some large and medium-sized feed enterprises must do everything possible to reduce costs in order to survive. Therefore, palm kernel meal has been used to replace some corn.
