What are by-products and how are they used in horse feeds?
Grains and other plants are processed to produce many different foods for human consumption, such as flour, cooking oils and syrup. The parts of the grain or plant that remain after processing are known as by-products. Many by-products contain nutrient levels or attributes that make them better feed ingredients for horses than the initial grain or the primary end-product of the processing.
