Secondary plant metabolites, also referred to as anti-nutritional factors (ANFs), cause depressions in growth performance and animal health due to a variety of mechanisms including reducing protein digestibility, binding to various nutrients or damaging the intestinal wall, thereby lowering digestive efficiency. The type and content of these ANFs varies considerably among different feedstuffs: Protease inhibitors and lectins are most significant for legume seeds (soybeans, peas, faba beans, lupins), tannins are present in rapeseed, faba beans and peas, whereas glucosinolates and sinapins dominate in rapeseed. Finally, alkaloids are important in lupins, and pyrimidine glycosides can generally be found in faba beans. These ANFs exert various deleterious effects on monogastric animals, and some of the means and strategies to reduce or to even eliminate negative effects of ANFs will be described.
