Embodiment

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

[0039] A. The acquisition of strains

[0040] Paecilomyces gunnii Z.Q.Liang and its variants are widely distributed species. The strains can be obtained by collecting mature Cordyceps guni (including variants) in the field, collecting the ejected ascospores, transferring them to a sterile culture medium for separation and purification, or using tissue separation after surface disinfection of the sporozoites. Methods The strains were obtained by separation and purification.

[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 extr...

Abstract

A nutritive cordyceps additive of forage for promoting growth of fowls and animals, and improving the taste of egg and meat is prepared from Paecilomyces Guni, through slant culture, liquid seed culture, liquid fermenting, culturing in solid medium, etc.

Description

technical field [0001] The invention relates to a production method of a nutritive Cordyceps feed additive, in particular to a production method of a novel feed additive which is cultured, liquid fermented and solid substrate cultured with Paecilomyces gunnii Z.Q.Liang. 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, Chinese he...
