Biological additive for animal feed and method for preparing same

Abstract

The invention discloses a biological additive for animal feed, which comprises the components of bacillus subtilis solution, yeast solution, lactic acid bacteria solution, acetic acid bacteria solution, beer yeast solution and vegetable lactic acid bacteria solution in a ratio of 0.4-1:1:0.6-1.5:0.6-1.5:0.6-1.5:0.3-0.7. After being mixed with the feed and drinking water and entering intestinal canals of animals, the biological additive can build a free dominant species with beneficial bacteria in the intestinal canals so as to inhibit and kill harmful pathogenic bacteria; and simultaneously, a great deal of nutrients such as amino acids, proteins, vitamins, biochemical enzymes, antibiotics, somatomedins and the like are secreted and synthesized, so that the functions of all organs of the animal body are adjusted and improved, the feed conversion rate is improved, the animals are stimulated to generate immunity, to be nourished, to grow and the like, and the effects of deodorizing manure, preventing and controlling diseases, improving survival rate, enforcing growth and breeding, cleaning the environment, improving economic benefits and the like can be achieved.

Description

technical field [0001] The invention relates to a strain mixture, in particular to a biological additive for livestock and poultry feed and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards and the continuous increase of population, the requirements for the output and quality of livestock and poultry are getting higher and higher. [0003] In the prior art, the method of adding chemical hormones is often used to increase the reproductive rate of livestock and poultry, promote growth, and shorten the feeding time, so it is easy to cause chemical hormone residues in the finished products of meat, eggs, and milk. Livestock and poultry are susceptible to bacterial infection, and are easy to spread diseases, causing epidemics in livestock and poultry. Treatment with veterinary drugs is likely to cause antibiotic drug residues and affect the quality of their meat, eggs, and milk. Contents of the invention ...
