Abstract

The invention relates to a special enzyme for growing pigs and a preparation method thereof, belonging to the field of feeding enzymes. The special enzyme for growing pigs comprises the following components in parts by weight: 0.5-2 parts of Chinese herbal medicine powder, 20-40 parts of xylanase, 5-8 parts of protease, 2-5 parts of pectinase, 8-16 parts of cellulase, 10-20 parts of beta-glucanase, and 2-6 parts of intermediate temperature alpha-amylase, wherein the production strain of cellulase is trichoderma reesei 601-17, and the preservation number is CCTCC (China Center For Type Culture Collection) M2013540. The preparation method comprises steps of cultivating slope strains so as to obtain liquid seeds; fermenting by a method combining low temperature and step-by-step inoculation; and centrifuging the fermentation liquor, collecting, concentrating, filtering, drying so as to obtain the cellulase. After being concentrated and dried, the cellulase further improves the unit activity and vitality, effectively supplements insufficient endogenous enzyme, promotes digestive absorption of nutrient substances, and improves the use ratio of fodder.

Description

technical field

[0001] The invention belongs to the field of enzyme preparations, and in particular relates to a composite enzyme and a manufacturing method thereof. Background technique

[0002] Scientists from the former Soviet Union added starch dextrinase to the diet of early weaned piglets, which increased daily weight gain by 14.6% and carbohydrate digestibility by 77.2%. According to relevant reports in the United States, Collier supplemented the diet of early-weaned piglets with enzyme preparations (including protease, amylase, and dextranase). As a result, the daily gain of the experimental group was 25% higher than that of the control group, and the feed conversion rate was increased by 15.5%. %. Scholars in West Germany have conducted many experimental studies on adding compound enzyme preparations to fattening pigs. Adding 0.1% compound enzyme preparations to barley-based diets, the results are: the growth rate of the experimental group increased by 5.1% compare...
