Lupines (Lupinus spp.) as a protein feedstuff for poultry. 2) Results of poultry feeding trials and recommendations on diet formulation

The present paper addresses the growing importance of sweet lupines (Lupinus ssp.) as domestic protein feedstuffs promoted by various governmental measures. Although the use of lupines in practical poultry diets in Poland and Germany remains marginal, extensive research into their nutritional value has been conducted both nationally and internationally. The first communication discussed the botanical and breeding characteristics of lupines, lupine cultivation and production, followed by information on the composition, protein quality and feed value of lupines. The second communication, based on experimental results, focused on the possibilities and limitations of incorporating lupine seeds in practical diets for chickens, turkeys and waterfowl, and on providing recommendations for the use of lupine in poultry nutrition. The influence of lupines on GIT parameters and their possible implications for gut health in poultry were also discussed. The above data were used to formulate objectives for future research.
