어분 is a type of fish meal made from ground fish, often used as a protein source in animal feed. It is produced by cooking, drying, and grinding fish, which helps preserve its nutrients. This ingredient is commonly used in the diets of livestock, poultry, and aquaculture to promote growth and health. In addition to animal feed, 어분 can also be found in some human food products, particularly in regions where fish is a staple. It is valued for its high protein content and is sometimes used in the production of pet food and fish feed for aquaculture.
