Feed additive and preparation method and application thereof

Abstract

The invention provides a feed additive, a preparation method and application thereof and relates to the technical field of livestock and poultry breeding. The feed additive is prepared from the following components: beta-glucanase (3.0-5.0)*105 U / kg, beta-mannanase (0.5-1.0)*105 U / kg, xylanase (4.4-6.6)*106 U / kg, cellulase (3.0-6.0)*104U / kg, bacillus subtilis greater than or equal to 6000 CFU / kg,bacillus licheniformis greater than or equal to 4000 CFU / kg, bacillus coagulans greater than or equal to 5000 CFU / kg, lactobacillus plantarum greater than or equal to 4000 CFU / kg, clostridium butyricum greater than or equal to 6000 CFU / kg and antimicrobial peptide of 5% or above. The feed additive can improve the utilization rate of daily ration of livestock and poultry and improve the immunity oflivestock and poultry. The use of the feed additive for livestock and poultry feed can significantly improve the production performance of livestock and poultry, reduce the cost of feed, and also reduce the use rate of antibiotics, and the additive is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry feeding, in particular to a feed additive, a preparation method and an application thereof. Background technique [0002] At present, in order to improve the immunity of livestock and poultry, antibiotics are usually added to the diet of livestock and poultry. In the actual application of antibiotics, there are relatively serious abuses in our country. Although antibiotics have a certain antibacterial effect, long-term use and excessive use will cause drug-dependent problems of pathogenic bacteria, resulting in drug-resistant bacteria that cannot be killed by antibiotics, seriously endangering human food safety. [0003] In recent years, new green and environmentally friendly feed additives such as compound enzyme preparations and microecological preparations have the foreseeable prospect of replacing antibiotics. At the same time, because the research in my country started later t...

AI Technical Summary

Problems solved by technology

In addition, compound enzyme preparations and microecological preparations have problems of process standardization and standard uniformity, the formula is relatively chaotic, and the actual application effect lacks uniformity

The research on the interaction between green environmental protection feed additives and other additives and the mechanism of their influence is not deep enough

[0004] At present, many studies have shown that the use of probiotics and compound enzyme preparations alone will have a good effect, but the actual application effect is not as good as that of antibiotics. Therefore, there is still a long way to go for probiotics and compound enzyme preparations on the road to replace antibiotics
