Special compound enzyme containing cellulase for piglets and preparation method thereof

Abstract

The invention discloses a special compound enzyme containing cellulase for piglets and belongs to the field of preparation of feed enzyme. The special compound enzyme is characterized by comprising the following components in parts by weight: 1-3 parts of Chinese herbal medicine powder, 15-20 parts of xylanase, 5-10 parts of cellulose, 10-20 parts of beta-dextranase and culture, 3-5 parts of mannose, 2-10 parts of protease and 2-5 parts of medium-temperature alpha- amylase, wherein the production strain of the cellulose is trichoderma reesei601-17, and the collection number is CCTCC M 2013540. The preparation method comprises the following steps: culturing the strain on an inclined plane to obtain liquid seeds; adopting a method with combination of low temperature and step-by-step inoculation at the fermentation stage; carrying out centrifugation, collection, concentration, filtering and drying on the fermenting liquid to obtain the cellulose. The special compound enzyme has the advantages that since the cellulose, the beta-dextranase and culture contain probiotics and enzymic preparations, the digesting and absorbing efficiency can be effectively improved and the health of animal intestines can be improved.

Description

technical field [0001] The invention belongs to the field of enzyme preparations, and in particular relates to a composite enzyme and a preparation method thereof. Background technique [0002] In order to overcome various problems of suckling pigs after weaning, most enterprises start from supplementary feeding before weaning, food inducement, acidification of rations, use of feed materials with good palatability and easy digestion and absorption, adding exogenous enzymes, and reducing antigens in rations. Improvements and optimizations have been made in many aspects, such as stability, reducing the crude protein content of the diet, and using accelerators, but the actual effects are uneven. [0003] Considering that when piglets are weaned, their own protease, amylase and other enzyme activities are greatly reduced to one-third of those at weaning, and these enzymes play a vital role in obtaining nutrition and energy for piglets. At the same time, feed enzymes have good e...
