Abstract

The invention relates to a beta-glucanase containing special enzyme for growing pigs and a preparation method thereof, belonging to the technical field of feed enzyme preparations. The special enzyme for growing pigs is prepared from the following enzyme preparations in parts by weight: 0.5-2 parts of Chinese herbal medicine powder, 80-100 parts of xylanase, 20-40 parts of protease, 10-20 parts of pectinase, 10-15 parts of cellulase, 15-25 parts of beta-glucanase and 10-15 parts of medium-temperature alpha-amylase, wherein the beta-glucanase is produced from bacillus licheniformis beta-10-25, has the collection number of CCTCC No: M2013538, and is prepared by a preparation method which comprises the following steps: carrying out inclined-face strain activation and culture, so as to obtain a liquid seed; at a fermentation stage, adopting a low-temperature culture medium supplementing and batched inoculating combined method; filtrating, concentrating, fine-filtrating and drying fermentation liquor, thereby obtaining beta-glucanase with good thermal stability. According to the compound enzyme, the conversion ratio of feed can be increased, and the cost of the feed can be reduced.

Description

Technical field: [0001] The invention belongs to the technical field of enzyme preparations, and in particular relates to a special enzyme for growing pigs and a preparation method thereof. Background technique: [0002] With the development of modern enzyme technology and biotechnology, high-efficiency biologically active substances—enzyme preparations have been able to be industrially produced on a large scale and used in the feed industry. Many experiments and practical application results have shown that feed enzyme preparations are used as A feed additive can effectively improve feed utilization, promote animal growth and prevent animal diseases. Compared with antibiotics and hormones, it has excellent safety and has attracted great attention from the feed industry worldwide. [0003] Feed enzyme preparations are enzymes added to feed to improve animal digestion and utilization of feed or to improve metabolic performance in animals. Enzyme preparations that can be adde...
