Embodiment approach 1

[0020] Implementation method 1: Add the bacteria powder into a certain amount of water according to the proportion of 0.4% of the feed to resuscitate for 1.5 hours, then add water to the feed to add water to 30-40% of the total weight and ferment for 2-6 hours before feeding;

Embodiment approach 2

[0021] Implementation method 2: add the bacterial powder into a certain amount of water at a ratio of 0.05%, resuscitate for 1.5 hours, add it to drinking water and mix it, and then drink it directly.

Abstract

The invention relates to a preparation method of a compound microbiological feed additive for fattening pigs, and an application method of the compound microbiological feed additive for fattening pigs. The compound microbiological feed additive for fattening pigs includes four different kinds of compound microbiological flora powders: 45 percent of lactobacillus helveticus, 45 percent of lactobacillus fermenti, 5 percent of bacillus subtilis, and 5 percent of bacillus licheniformis. The application method of the compound microbiological feed additive for fattening pigs is as follows: the compound bacterium powders are added into feed by a ratio of 0.4 to 100, or added into drinking water by a ratio of 0.05 to 100. The preparation method of the compound microbiological feed additive for fattening pigs includes the following steps: through liquid fermentation and with soybeans serving as a fermentation raw material, the bacteria respectively achieve a logarithmic phase (pH4-5) through twice enlarged cultivations; bacterium powders with water contents no higher than 5 percent and bacterial counts no lower than 10<8> per gram are obtained through spray drying; the compound bacterium powders are finally obtained. The compound microbiological feed additive provided by the invention effectively prevents disease infection and spreading among fattening pigs, greatly improves the meat quality and the dressing percentage, reduces the application of antibiotics and chemical additives, saves feed and cultivating water, improves economic and social benefits, and is an ideal compound microbiological feed additive.

Description

technical field [0001] The invention relates to a method for preparing and using a compound microbial feed additive for fattening pigs, and belongs to the field of fermentation engineering. Background technique [0002] For a long time, the pig industry at home and abroad has used antibiotics or various other chemical drugs and bacteriocins to solve the disease susceptibility problems encountered in the process of raising pigs or to accelerate the growth rate of fattening pigs. However, due to the extensive use of chemical drugs and antibiotics, the normal flora of the gastrointestinal tract of pigs 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...
