Application of Cellulolytic and Plant Tissue Macerating Enzyme of Irpex lacteus Fr. as Feed Additive Enzyme

The effects of supplementation of enzyme preparation (Driselase, DRS) produced by Irpex lacteus Fr. (KY 2902) on feeding animals were studied.When 0.01~0.03 % of DRS were supplemented to broiler diets which contained about 60% corn, body weight gain and feed conversion were significantly improved at 10% and 5% level, respectively. When 0.01~0.03% of DRS were supplemented to broiler diets which contained about 60% of barley, body weight gain and feed coversion were also improved significantly at 1% level each. DRS supplementation improved feed efficiency of barley to the level of corn.In case of piglets when 0.01% of DRS was supplemented to artificial milk, body weight gain increased significantly at 5% level. Feed conversion was improved about 9%. The digestibility of crude protein, fat and fibre in the ration increased by about 2.4%, 1.7% and 6.3 %, respectively.
