Fodder beans are used in agriculture for fodder purposes. They are distinguished by their feed value. Recent studies have shown that beans can be used to replace soybean meal in pig diets, as well as in beef production. Despite the presence of tannin in the seed coat of beans, experiments have shown that feeding pigs a relatively high proportion of beans during the stages from growing to finishing pork production has no harmful effects (Houdijk et al., 2013), but because the amino acid profile of beans lacks sulfur-containing amino acids, some balance must be achieved by using synthetic substances.
