Jansman, A.J.M. Buraczewska, L. Huisman, J. van Leeuwen, P. Centraal Instituut voor Voedingsonderzoek TNO Publication year 1997 Abstract Eighteen cannulated piglets were used in two experiments (six in Experiment 1 and 12 in Experiment 2) to determine the effect of supplementation of the diet with microbial α-galactosidase on the ileal digestibility of the raffinose family oligosaccharides and other nutrients of lupin-based diets. Three semi-purified diets with the seed meal of yellow lupin (Lupinus luteus L.) cvs Juno and Amulet or narrow-leafed lupin (Lupinus angustifolius) cv Saturn were offered to pigs with or without the enzyme supplementation (5 g kg-1). About 80% of the α-galactosides were digested up to the end of the small intestine of pigs (Experiment 1) fed on the diet with cv Juno without the enzyme supplementation. When α-galactosidase was added to the diet, digestibility of α-galactosides significantly increased to 97%. Results of Experiment 2 showed that the ileal digestibility of sucrose (92.9%), stachyose (71.9%) and verbascose (83.4%) of narrow-leafed lupin cv Saturn was higher than the corresponding values for yellow lupin cv Amulet (86.3, 60.1 and 77.8%). The ileal digestibility of raffinose was 52.2% for cv Saturn and 40.7% for cv Amulet. The ileal digestibility of total non-starch polysaccharides (NSP) was 11% for cv Amulet and 14% for cv Saturn. α-Galactosidase supplementation significantly improved the digestibility of the raffinose series oligosaccharides and positively affected the ileal digestibility of most amino acids (P < 0.05). © 1997 Elsevier Science B.V.
