Utilization of the raw beans for food and feed is prohibited by the presence
of protease inhibitors. Breeding soybean cultivars for reduced amount of anti
nutritional factors at Maize Research Institute Zemun Polje resulted in
development of two new Kunitz-free cultivars - Lana and Laura. Feeding trials
with pigs in different growth stages were conducted to compare the response
of growing and finishing pigs to diets containing either raw or extruded
standard and KTI-free (Kunitz trypsin inhibitor-free) soybean cultivars. The
greatest improvement in growth performance was noted for the group fed
extruded KTIfree soybean. This group achieved highest daily weight gain and
gain per feed unit. Growth parameters for group of pigs fed raw soybean
Kunitz-free cultivar were slightly reduced.
