Preparation method of cordyceps feed additive

Abstract

The invention relates to a preparation method of a feed additive, in particular to a preparation method of a cordyceps feed additive. According to the method, the cordyceps feed additive is prepared from cordyceps sinensis anamorphic strains of paecilomyces hepialid for inclined plane culture, liquid fermentation, solid fermentation and later-stage curing process, the cordyceps feed additive is different from microbial viable preparations and is different from ordinary cordyceps products, the defects of products in the prior art are overcome, the effect ingredients of the cordyceps is remained to the maximum degree, in addition, grain bran powder in production raw materials of products are converted into bifidus factors through microorganism via the degradation process in the specific high-temperature sterilization process, the animal growth can be preferably promoted, the feed conversion rate is improved, the cost is reduced, in addition, the animal immunity and the disease resistance can be improved on the premise of not using medicine or using little medicine, the survival rate is improved, and the cost is reduced.

Description

technical field [0001] The present invention relates to a preparation method of a feed additive, in particular to a preparation method of a feed additive of Cordyceps sinensis, which is produced by adopting the anamorphic strain of Cordyceps sinensis-Paecilomyces spp. The invention discloses a feed additive for cordyceps, which belongs to the technical field of feed additive processing. Background technique [0002] At present, most of the additives used in the feed are antibiotics, chemically synthesized drugs, hormones, etc. They are easy to remain in the animal body. Long-term use will cause the farmed animals to develop drug resistance or remain in the final products of the farmed animals (meat, eggs, milk, etc.) ), pose a threat to food safety, directly or indirectly cause harm to human health, and cause damage to the body. Green feed additives represent the future development direction. In a broad sense, they will refer to natural additives that are pollution-free, re...

AI Technical Summary

Problems solved by technology

The former is mainly because the patent involves a wide range of known and unknown strains of hundreds of species, but different species of Cordyceps, different fermentation processes, different functional components, and different effects, and even some products are toxic, such as Stinkworm , it is currently known that the active ingredients and health functions of Cordyceps and anamorphs are less

The implementation of this patent uses Paecilomyces. The problem is that Paecilomyces mentioned here is a large genus, which means that it contains all Paecilomyces, but Paecilomyces is produced by different medium formulations and different fermentation processes Products with different functions, some can be used for animal health, some can not even be harmful

The strains used in the latter patents are different species of Paecilomyces, but the fermentation process is relatively traditional and the conditions are complicated to control
