Agri-Food and Biosciences Institute (AFBI - United Kingdom) studies lupins in poultry diets
Lupins can contain up to 44% crude protein. Previous research has shown they can be included in poultry diets with no adverse effects on performance provided the diets are supplemented with expensive synthetic amino acids. There is a lack of information on the use of low levels of lupins in poultry diets as a direct substitution for soybean meal, without additional amino acid supplementation.
Conclusions: Lupin inclusion reduced feed intake and growth rate in poultry, and there is limited potential for lupins to be used as an alternative protein source.
