Problems solved by technology

The long-term pilot test found that there are problems in the constant temperature solid fermentation of "20℃~30℃ constant temperature solid fermentation": the germination period is long and easy to pollute, the logarithmic growth is too fast and the heat dissipation is not timely and easy to burn the plate
That is: if cultured at a low temperature of 20°C at a constant temperature, the growth of bacteria will be slow, the growth period will be prolonged and easy to be polluted, and the number of bacteria points will cause the growth of th

Abstract

The invention discloses a production method of a feed additive 'Acremonium terricola culture'. The production method has the beneficial effects that by researching growth characteristics of Acremonium terricola strains and improving a production process of the Acremonium terricola culture, the production period of the Acremonium terricola culture is shortened from original 11-15 days to 5 days, the production cost of the Acremonium terricola culture is substantially lowered, and the production method has an important significance to the market promotion of the high-end feed additive; meanwhile, the energy loss of water, gas and electricity in the production process is greatly reduced. According to the production method, the production process of the Acremonium terricola culture mainly comprises the steps of 'liquid strain fermentation' and 'solid fermentation'. According to an animal test result, by utilizing the feed additive, the immunities of animals are improved, the feed conversion ratio is lowered, and the meat quality is improved. The production method has the advantages of low cost, short production period, controllability in control, good application effect and the like.

Description

technical field [0001] The invention belongs to the technical field of feed additive processing, and in particular relates to a production method of a feed additive "Acremonium acremonium culture", more specifically using acremonium acremonium ( Acremonium terricola , preservation number CGMCC0346) and a production method of Acremonium acremonium culture obtained by liquid strain fermentation and solid fermentation. Background technique [0002] Most of the feed additives in the "Catalogue of Feed Additives" issued by the Ministry of Agriculture of my country are traditional antibiotics and chemically synthesized drugs. The transfer of antibiotics has a huge impact on human health, and even threatens the safety of human life; and the human body often ingests low doses of antibiotic residues from meat, which will gradually accumulate in the body and cause lesions in various organs, leading to allergic reactions , immunosuppressive, teratogenic, carcinogenic, mutagenic and othe...
