Digestion of extruded
starch is poorly characterized. Two diets containing wheat or faba bean starch were extruded individually or combined
50:50 (wt/wt) and fed to weaned pigs. Ileal starch digestion tended to be higher (P<0.10) for the extruded wheat diet than the extruded faba bean diets, while total tract digestibility of starch and energy was higher (P<0.05) for the two extruded faba bean starch diets than the extruded wheat diet. Feed intake tended to be higher (P<0.10) for extruded faba bean starch diet, but final body weight was not affected by extruded starch source. The in vivo kinetics of starch and energy digestion differed between extruded wheat and faba bean starch diets.
