Embodiment 1

[0019] Embodiment 1, the acquisition of bacterial classification

[0020] 1. Acquisition of Bacillus subtilis Bs006 CGMCC No.2434

[0021] 1. Acquisition of strains

[0022] 1. Take one gram of soil from Taichung County, Taiwan, and add 10ml of Trypticase TM Soy Broth (TSB culture solution; each liter contains tryptone 20.0g, dextrose 1.0g, disodium hydrogen phosphate 2.0g, potassium nitrate 1.0g, adjust the pH to 7.0, add 1.5% agar to the solid medium) and shake and mix After uniformity, it is sterilized by conventional pasteurization.

[0023] 2. The TSB culture solution was diluted 10 times to 10 -4 , each serial dilution was incubated at 37°C for 24 hours, and the initial enrichment screening of spore-forming strains was carried out.

[0024] 3. Then take 100 μl from each dilution tube onto a TSA (Trypticase Soy Agar, Difco, Sparks, U.S.A.) plate, spread evenly with an L-shaped glass rod, and culture at 37°C for 24 hours, and then pick a single colony by random select...

Abstract

The invention discloses a fodder premix and a special bacterial strain thereof; lactobacillus delbrueckii subspecies ST007 with the collection number of CGMCC No.2433 is provided by the invention; inthe fodder premix, active constituents are culture which is obtained by fermenting a substrate with bacillus subtilis Bs006 CGMCC No.2434 and lactobacillus delbrueckii subspecies ST007 CGMCC No.2433;the substrate is at least one of bean pulp, horsebean pulp, rape seed dregs, bean flour and cornmeal. The fodder premix has the characteristics of no toxicity, no drug resistance and no side effect, and can be added in various animal fodders, so as to remarkably promote the growth of animals, improve the fodder conversion ratio and enhance the immunity of the animals. The preparation method of thefodder premix is simple and has low cost, thereby having great economic value and social significance.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a feed premix and special bacterial strains thereof. Background technique [0002] Generally, substances that can be eaten by animals and can give animals one or more nutrients are collectively referred to as feed. As the population increases year by year and human eating habits change, the demand for animal food increases, and the demand for animal feed also continues to increase. According to the estimates of "International Feed", the output of the global feed industry in 2002 reached 600 million 4 million tons. However, the rapid development of animal husbandry and feed industry also brings some side effects, one of which is the abuse of antibiotics. The abuse of antibiotics can easily lead to endogenous infection or superinfection of livestock and poultry; the use of antibiotics in feed leads to drug residues in animal products, which directly threatens human health; the transfer...
