used to make feeds such as soybean meal and hulls, rice bran, and beet pulp. For concentrates, processing enables the manufacturer to make consistent products. In turn, the products become safer, easier to chew, and more appetising for the horse. Processed forages such as hay cubes or pellets can make the most efficient use of limited storage space, fill in when a hay crop has failed, make it easier to carry feed when travelling, guarantee a consistent intake of nutrients, simplify ration balancing, and help horses with problems such as poor teeth or respiratory tract disorders.

Grain and forage processing Grains are processed to increase digestibility. Crushing, cracking and grinding, particularly of corn and lupins, are performed to reduce the particle size. Other effective processing methods are crimping, flaking, and the rolling of oats and barley. These techniques open the outer coat of the grain to aid chewing. Adding heat to
