comparison of the extent and site of energy and protein digestion of wheat, lupin and meat and bone meal by pigs

The ileal digestibilities of dry matter (DM), nitrogen (N), energy and amino acids were measured using pigs prepared with either re‐entrant or simple ileal cannulae and fed a basal wheat diet, a wheat/lupin diet and a wheat/meat and bone meal (MBM) diet. The same pigs were also used to determine the faecal digestibilities of DM, N and energy in these diets. Addition of lupins to the basal diet had no significant effect on the true digestibilities of amino acids but addition of MBM significantly (
