Lupins can be fed as part of a balanced diet to all animals. There are two basic types of lupins – bitter and sweet varieties. The ones currently grown commercially as a stock feed in Australia are the sweet types.
Crushed, untreated lupin seed of sweet varieties can be included in diets of poultry and livestock of all ages. For poultry, broiler diets containing lupins as the sole protein concentrate can be fed without an adverse effect provided that the lysine and methionine levels are maintained. Similarly, lupins have been shown to be able to replace half of the meat meal used in layer diets with any adverse effect on layer performance.
