FEEDING OF WHITE AND YELLOW LUPINS (LUPIN US-ALBUS L AND LUPINUS-LUTEUS L) IN COMBINATION WITH ENZYME SUPPLEMENTS TO PIGLETS

In a 2 factorial rearing experiment with 48 piglets (German Landrace x Pietrain, initial weight 7.1 kg) the feeding of white and yellow lupi ns (Lupinus albus L., var. Lublanc and Lupinus luteus L., var. Borsaja ) was tested in combination with the enzyme Roxazyme(R) G over 6 weeks . The proportions of the lupins were 15 % white and 30 % yellow lupins , the enzyme supplementation was adjusted to 200 mg Roxazyme G per kg of feed. The rations were isonitrogeneous (20 % XP in dry matter) and isoenergetic (15.2 MJ ME per kg dry matter). The white/yellow lupins c ontained 0.08 % alkaloids in dry matter and 1330/102 mg manganese per kg dry matter. Both lupin proportions produced significantly lower per formance. Daily weight gains were reduced by 27 % with 15 % white lupi ns and by 37 % with 30 % yellow lupins. Also feed intake was decreased significantly in a similar extent compared to the controls. The enzym e supplementation was of no influence in all groups.
