The abstract for a study on the effects of including lentils in the diets of pigs 1 week post-weaning. Lentils replaced soybean meal and wheat for an up to 30% inclusion. Including lentils reduced total tract digestibility, feed efficiency, and weight gain. Growth performance was affected at 30%, with lower final weights being observed; therefore, it would not be recommended to include lentils over 22.5%.
