This invention relates to the field of feed science and technology, specifically to a feed preparation method for improving the appearance, oiliness, and color of pig concentrate. The concentrate consists of a main ingredient and auxiliary ingredient system. The main ingredient core includes 100-350 parts of 46% protein dehulled soybean meal, 150-300 parts of high-temperature, high-pressure hydrolyzed feather meal, 15-30 parts of grade IV degummed soybean oil, and 15-40 parts of phospholipid oil powder, etc.; the auxiliary ingredients include fruit and milk flavoring agents that target the olfactory preferences of growing pigs.
