Thirty 21-day-old pigs(Duroc×Landrace×Pietrain) were assigned to 3 groups,10 pigs for each group. The experimental period was 30 d. The basal diet was consisted of corn and soybean feedstuffs without antibiotics as the control group;and the other 2 diets were added with 0.02%,0.03%lipase respectively. The result indicated that the final weight in group1 and 2 increased 8.53%(p<0.05),6.73%(p<0.05) respectively,and the average daily gain(ADG) increased 14.17%(p<0.05),12.67%(p<0.05) respectively,while the feed conversion decreased 15.66%, 13.25% respectively,compared with the control group. The diarrhea rates in group 1 and 2 decreased 10% and 30% respectively,and analysis of economic benefits indicated that the net income of group 2 and 3 incerased 39.17 and 33.65 yuan per pig respectively,compared with the control group.
