Embodiment

[0032] Embodiment: one, the making of compound microbial fermentation agent: used bacterial classification is common bacterial classification, all can buy from the market and directly be made into bacterial liquid and use. Some varieties can also be cultivated according to conventional methods according to needs, and microorganisms with pure varieties, tenderness, strong reproductive ability and high density have been obtained. The method is as follows: ① Put the collected microorganisms into a sterilized triangular flask, add sterilized water, shake it evenly and let it stand still, take its supernatant, and dilute it with sterilized water to a concentration of 10 -4 、10 -5 、10 -6 suspension. ②Use a sterilized pipette to draw suspensions of different concentrations, filter through a sieve filter, inoculate on broth agar medium, and culture anaerobically at 25°C-37°C for 2-3 days. ③Under an electron microscope, use a steam-sterilized inoculation needle (or ring), hook the i...

Description

technical field [0001] The invention relates to a feed nutritional additive, in particular to a compound microbial fermented feed nutritional additive and a preparation method thereof. Background technique [0002] In my country, pork occupies a very important position in meat products. With the continuous improvement of people's living standards, people's demand for pork products is increasing, and people are increasingly concerned about whether it is green and environmentally friendly. This puts forward higher requirements for our pig industry: on the premise of ensuring the feed is green and environmentally friendly, how to reduce costs, improve the digestion and absorption rate of pigs for feed, increase the growth rate of pigs, and improve the conversion rate of feed and meat is a matter of fact. The fundamental question of whether the pig industry can develop sustainably. Therefore, more and more attention has been paid to the method of making feed additives by utiliz...
