preparation example Construction

[0028] The present invention also provides a preparation method for the above-mentioned feed additive powder, comprising the following steps:

[0029] Mix yeast, Bacillus subtilis, Pediococcus lactis, Lactobacillus plantarum, Enterococcus faecalis, Lactobacillus acidophilus, purple non-sulfur bacteria and bacterial cell protectant to obtain a compound bacterial agent;

[0030] The composite microbial agent is dried and pulverized to obtain feed additive powder.

[0031] The present invention mixes yeast, Bacillus subtilis, Pediococcus lactis, Lactobacillus plantarum, Enterococcus faecalis, Lactobacillus acidophilus, purple non-sulfur bacteria and a bacterial body protective agent to obtain a composite bacterial agent. In the present invention, it is preferred to firstly mix the bacterial liquids of yeast, Bacillus subtilis, Pediococcus lactis, Lactobacillus plantarum, Enterococcus faecalis, Lactobacillus acidophilus and Violet nonsulfur bacteria, and finally add the bacterial ...

Abstract

The invention relates to the technical field of feed additives, in particular to a poultry feed additive, poultry feed additive powder, a preparation method and application. The invention provides the poultry feed additive. The poultry feed additive comprises the following raw materials in parts by volume of 3-8 parts of saccharomycetes, 1-5 parts of bacillus subtilis, 4-7 parts of pediococcus acidilactici, 1-4 parts of lactobacillus plantarum, 3-6 parts of enterococcus faecalis, 2-5 parts of lactobacillus acidophilus and 1-3 parts of purple non-sulfur bacteria. The feed additive can reduce harmful gas in a breeding house and improve immunity and slaughter performance of poultry, time and labor are saved through a feed adding mode, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a poultry feed additive, a poultry feed additive powder, a preparation method and an application. Background technique [0002] In the poultry breeding industry, affected by the breeding mode and breeding cost, the harmful gas infringement produced by high-density breeding is an important factor restricting the development of poultry breeding. Harmful gases produced by poultry pens not only pollute the air in poultry pens, reduce poultry immunity and slaughter performance, but also lead to a decline in air quality in the farm area and nearby areas, and pose a certain threat to human health. Studies have found that the contribution rate of the environment to poultry productivity can reach 30% to 40%. Among many environmental factors, NH 3 、H 2 S and CO 2 It is an important index to evaluate the pollution degree of pens. [0003] At present, the measures to reduce harmfu...
