Embodiment 1

[0041]Antibiotic alternative deodorizing feed microecological preparation, said microecological preparation includes the following components in weight ratio: 200 parts of coated Lactobacillus plantarum, 200 parts of coated Enterococcus faecium, 20 parts of Bacillus subtilis and fructooligosaccharides 300 copies.

[0042] Preparation methods include:

[0043] 1. Preparation of multi-layer coated Enterococcus faecium microcapsules

[0044] (1) preparing concentration is the sodium alginate solution of 10g / L in the feeding tank of fermentation system;

[0045] (2) Weigh calcium carbonate at a ratio of 1:1 to the sodium alginate mass ratio, add it to the feeding tank, mix evenly, sterilize, then cool to 37°C, add Enterococcus faecium at the end of logarithmic growth Seed liquid, to a probiotic density of 1 x 10 6 -5×10 6 cfu / ml, fully mixed as the water phase;

[0046] (3) Add Span 80 as the oil phase to the liquid paraffin, the volume percentage of the Span 80 is 0.1%, and ...

Abstract

The invention discloses an antibiotic replacement type deodorizing feed microecological preparation as well as a preparation method and application thereof. The microecological preparation comprises following components in parts by weight: 200-300 parts of coated lactobacillus plantarum, 200-300 parts of coated enterococcus faecium, 20-50 parts of bacillus subtilis and 300-500 parts of fructo-oligosaccharide. The microecological preparation provided by the invention uses the coated lactobacillus plantarum and the coated enterococcus faecium, solves the problems of poor stress resistance of lactic acid bacteria, that is, short shelf life under a normal-temperature storage condition and easy inactivation in a feed granulation process. Besides, the microecological preparation disclosed by theinvention can reduce the content of odorous substances in animal waste, reduces the pollution of livestock and poultry breeding to the environment in the antibiotic-free breeding process, has the functions of promoting growth and deodorizing, and has important economic and social significance.

Description

technical field [0001] The invention belongs to the technical field of feed additives. More specifically, it relates to an antibiotic-substituting deodorizing feed microecological preparation and its preparation method and application. Background technique [0002] For a long time, the addition of antibiotics in feed has greatly promoted the development of animal husbandry, but with the popularization and application of feed antibiotics, its adverse reactions have gradually become prominent, such as: endogenous infection and cross-infection caused by antibiotics, drug resistance The production of livestock and poultry immunity, the destruction of normal intestinal flora and their residues in livestock products and the environment will pose serious threats to the breeding industry, feed industry and animals, and then endanger human beings through the food chain health. [0003] In addition, with the rapid development of my country's animal husbandry and breeding industry, t...
