Embodiment approach 1
[0020] Implementation method 1: add bacteria powder A to a certain amount of water according to the proportion of 0.2% of the feed to resuscitate for two hours, then add water to the feed to add water to 30-40% of the total weight and ferment for 4-8 hours before feeding;
Embodiment approach 2
[0021] Implementation method 2: Add bacteria powder A to a certain amount of water according to 0.3% of the feed ratio and resuscitate for two hours, then add water to the feed to add water to 30-40% of the total weight, and then feed directly;
Embodiment approach 3
[0022] Implementation method three: add bacteria powder A to the feed by 0.4% of the feed ratio and feed it directly;

The invention provides two different composite microbial flora powders, wherein a microbial flora A comprises 40% of lacbobacillus helveticus and 60% of lacbobacillus fermentum; and the microbial flora B comprises 50% of bacillus subtilis and 50% of bacillus licheniformis. The application method comprises that: the microbial flora powder A is added into a feedstuff according to a proportion of 0.2-0.4%, and the microbial flora powder B is added into drinking water according to a proportion of 0.05-0.1%. A preparation method comprises the steps that: with a liquid fermentation method, soybean is adopted as a fermentation raw material; through twice amplification, various strains are respectively cultured to a logarithmic growth phase (pH value is 4-5); microbial powder with water content no higher than 5% and viable cell amount no lower than 108 / g is obtained through spray-drying; and the microbial powder A and microbial powder B are obtained. With the additives provided by the invention, poultry and livestock disease infection and spreading can be effectively prevented; poultry and livestock product meat quality can be greatly improved, poultry and livestock slaughter rate can be improved, the use of antibiotics and chemical additives is reduced, feedstuff and culture water are saved, and economic and social benefits are improved. The additives are ideal composite microbial feed additives.
Description
technical field [0001] The invention relates to a method for preparing and using a compound microbial feed additive for omnivores, and belongs to the field of fermentation engineering. Background technique [0002] For a long time, the breeding industry at home and abroad has used antibiotics or various other chemical drugs and bacteriocins to solve the susceptibility of animal diseases or accelerate the growth rate of animals. However, due to the extensive use of chemical drugs and antibiotics, the normal flora of the gastrointestinal tract of animals is out of balance, and many pathogenic microorganisms are resistant to drugs, and drug residues occur at the same time. The use of antibiotics and chemical drugs not only reduces the quality of meat, but also the drug residues in animals seriously threaten human health. Although the abuse of antibiotics and chemical drugs has attracted the attention of the governments of various countries, the European Union has legislated to...
