Feed processing refers to the methods used to prepare animal feed for consumption by livestock. This process can include grinding, mixing, pelleting, and extruding ingredients to enhance their nutritional value and digestibility. By altering the physical form of the feed, it can improve feed efficiency and reduce waste. Additionally, feed processing can involve the addition of vitamins, minerals, and other supplements to ensure that animals receive a balanced diet. Techniques such as fermentation or heat treatment may also be employed to preserve feed quality and prevent spoilage, ultimately supporting the health and growth of animals like cattle, poultry, and swine.
