preparation example Construction

[0090]The preparation method of wort juice: use 2 times the water and 0.5 times the malt of the required wort dose: mash at 55-63 ° C for 4-6 hours and filter it with four layers of gauze to form the wort filtrate (use 0.02 mol / L iodine When the liquid is measured to be yellow to colorless, the saccharification is complete), the sugar concentration in the saccharification liquid is detected with a Baume hydrometer, the filtrate is diluted with water to 10-15 Paulines, and the pH is adjusted to 6.4.

[0091] Prepare Aspergillus niger and Aspergillus oryzae female species: the components of the female species medium and their weight ratios consist of: potato juice: glucose: corn steep liquor=100: 2: 1, and the nutrient solution was sterilized at 120° C. for 20 minutes, cooled to After 35°C, inoculate the strain at a weight ratio of 1 to 3%, and cultivate at a constant temperature of 30-35°C for 36-72 hours;

[0092] The preparation method of potato juice: peel the potatoes, remo...

Abstract

The invention discloses a microbiological feed additive for replacing antibiotics, mainly comprising bacillus subtilis, saccharomyces cerevisiae, aspergillus niger, aspergillus oryzae and the like. The preparation method of the microbiological feed additive comprises the following steps: parent species of all strains are prepared by liquid state fermentation, production species are prepared by carrying out solid state fermentation on the parent species, the strain is obtained by carrying out further solid state fermentation on the production species, and the strains are mixed according to a certain proportion to obtain the microbiological feed additive. The microbiological feed additive can improve the nonspecific immunity of animals, enhance the anti-stress capability of an organism, activate the growth potential of the animals, improve the production performance comprehensively, solve the problems of low quality of products, loss of flavor, diarrhea of piglets, constipation of sows,shapeless feces of chickens and ducks, more anti-nutritional factors of feedstuff materials and low digestion and utilization in a package manner, and provide a low-cost, simple and practical scheme for replacing the antibiotics, an enzyme preparation, arsenical preparations and probiotics.

Description

technical field [0001] The invention relates to a feed additive and a preparation method thereof, in particular to a microbial feed additive replacing antibiotics and a preparation method thereof. Background technique [0002] Since the advent of antibiotics in the 1940s, due to their miraculous effects in disease prevention, health care, growth promotion, and feed efficiency improvement, they have been used in all aspects in the aquaculture industry and reached their peak in the 1970s. [0003] According to the statistics of the World Health Organization in 2001, 90% of the total antibiotics consumed in the world are used for food animals, and about 12,000 tons and 900 tons of antibiotics are respectively used as feed additives and therapeutic drugs for food animals every year. In the treatment of animal diseases, the phenomenon of overuse of antibiotics is common. Many animal farms use antibiotics first when animals are found to be sick. Antibiotics are used in a larger a...
