Embodiment

[0038] The production method of the novel nutritional fungal feed additive comprises the following production steps:

[0039] A. The acquisition of strains

[0040] Paecilomyces cicadae (Mip.) Samson is a widely distributed species.

[0041] B. Bacteria culture in inclined test tube

[0042] Inoculate the isolated and purified strains into inclined test tubes, put them in a 25°C incubator, and cultivate for 7 days, until the hyphae are full of the test tubes and produce spores;

[0043] The weight ratio of the raw materials for the culture medium of the slant test tube is: glucose 40g, peptone 10g, yeast extract powder 10g, agar 20g, add water to 1L, pH6.5.

[0044] C. Liquid shake flask seed culture

[0045] Fill 200ml culture medium in 500ml Erlenmeyer flask, use 1.2Kg / cm 2 Autoclave for 30 minutes, and when it cools to room temperature, inoculate the strains passed through one inclined test tube into a 500ml Erlenmeyer flask culture medium, and place it in a constant te...

Abstract

The invention relates to the production method of paecilomyces cicadae new nutritious fungus feed addictive. The strain used in the method is traditional chinese herbal medicine paecilomyces cicadae. The process includes production processes such as acquisition of strain, cultivation of slant strains and liquid seeds, liquid fermentation, cultivation of solid substrate and so on. The result of animal test indicates that the fungus feed addictive can not only improve the feed conversion rate, save cost, gain meat animals' weight more quickly, reduce the cost by way of improving animal's immunological competence and survival rate with few medicine or no medicine, but also can achieve good effect on weight gains with little quantity of addictive. The production of the fungus feed addictive has advantages of wide raw material sources, easy production, low cost, controllable quality, convenient use, wide application, good actual effect and so on.

Description

technical field [0001] The invention relates to a production method of a novel nutritional fungal feed additive, in particular to a production method of a novel feed additive prepared by cultivating Paecilomyces cicadae (Mip.) Samson, liquid fermentation and solid matrix culture. Background technique [0002] Most of the non-nutritive additives used in the feed are antibiotics, chemically synthesized drugs, hormones, etc., which 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, etc.) , milk, etc.), directly or indirectly cause harm to human health, cause poisoning, drug resistance and "three causes" (carcinogenic, teratogenic, mutagenic) effects. Green feed additives represent the future development direction. In a broad sense, they refer to natural additives that are pollution-free, residue-free, disease-resistant, and growth-promoting. At present, ...
