THE EFFECT OF SUPPLEMENTAL NON-STARCH-POLYSACCHARIDE ENZYME ON GROWTH AND NUTRIENT DIGESTIBILITY OF WEANLING PIGS

More than 100 weanling pigs from 10 sows were studied the effect of adding non-starch-polysaccharide enzyme(NSPE) to corn-soybean diet on the growth and nutrient digestibility of weanling pigs.A corn-soybean diet as basic diet was used in all groups in this trial.Adding 120g/t NSPE to the diet used in the test groups,but on adding any NSPE to its diet for control one.The results showed that the digestibility of protein and organic matter of weanling pigs could be increased by 9.67% and 15.40%(P0.05), respectively.Adding NSPE to the corn-soybean diet,there was no obvious effect on the growth of weanling pigs before weanling,but there was an obvious positive effect on the weanling pigs from 0 to 14 day after weanling by increasing the daily gain of 10.40%(P0.05),increasing the total litter weight by 17.65%.The result also indicated adding NSPE to the weanling diet could decrease the weanling stress .
