Problems solved by technology

[0003] At present, the veterinary microecological premix products on the domestic market mainly have the following deficiencies: (1) The content of live bacteria is low. 7 1 / g, the enzymes and metabolites produced by the bacteria are not enough to affect the host, and it is difficult to meet the needs of treatment; (2) The stability to gastric acid and bile is poor, so that only a few strains are still active after entering the intestinal tract, and cannot play a role. The number of viable bacteria required; (3) poor proliferation rate in the body; (4) not resistant to high copper, unstable during high temperature processing and storage, and short shelf life; (5) few compound premixes, only suitable for a specific animal
This affects the application effect of the probiotic premix on animals and limits the scope of application of the probiotic premix

Abstract

The invention relates to a preparation method of an efficient composite micro-ecologic premix for animals, and belongs to the technical field of micro-ecologic preparation feed additives. The preparation method comprises the following steps: a step of respective optimal screening of Bacillus licheniformis, Bacillus subtilis, Candida utilis and Saccharomyces cerevisiae, a step of bacterial strain rejuvenation, a step of shaking culture, a step of culturing in a 30L fermentation cylinder, a step of thallus spray drying, and a step of preparing composite bacterial powder. The efficient composite micro-ecologic premix prepared through the method has the characteristics of excellent acid, salt, thermal and bile resistances, high content of live bacteria, high-copper tolerance, and good stability under feed granulation processing and normal temperature preservation conditions, the preparation method of the premix is simple and has a low cost, and the premix product produced through the method has a stable and reliable quality, and has a good market prospect.

Description

technical field [0001] The invention relates to a preparation method of a microecological premix, more specifically to a preparation method of a high-efficiency compound microecological premix for animals, and belongs to the technical field of probiotic feed additives. Background technique [0002] Veterinary micro-ecological premix is ​​a natural, green and safe feed additive. Due to its advantages of non-toxic, harmless, no residue and no pollution, it can prevent and treat diseases, improve feed utilization, and improve animal health. Production performance and other effects, and can overcome the bacterial flora imbalance, superinfection and drug resistance caused by antibiotics, and have been widely studied and applied in the case of increasingly prominent animal-derived food safety problems. [0003] At present, the veterinary microecological premix products on the domestic market mainly have the following deficiencies: (1) The content of live bacteria is low. 7 1 / g, t...
