preparation example Construction

[0019] The method for preparing the synbiotic additive of the present invention generally comprises the following steps:

[0020] First, at least one of 1 to 5 parts by weight selected from chitosan, chitosan and seaweed oligosaccharide, 2 to 10 parts by weight selected from at least one of astragalus polysaccharide, wolfberry polysaccharide and hawthorn flavonoids, and 100 parts by weight of A probiotic preparation composition, wherein the probiotic preparation composition is composed of Bacillus subtilis, Bacillus coagulans and Clostridium butyricum with a weight ratio of 1-3:1-3:1-3.

[0021] Then, at least one of the above-mentioned selected from chitosan oligosaccharides, chitosan and seaweed oligosaccharides, at least one selected from astragalus polysaccharides, wolfberry polysaccharides and hawthorn flavonoids, and the probiotic composition are mixed uniformly, so as to obtain the synbiotic Vegetarian feed additive.

Abstract

The present invention discloses a synbiotic feed additive, and a preparation method and applications thereof. The synbiotic feed additive comprises: 1 ~ 5 parts by weight of, preferably 2-4 parts by weight of, more preferably 3-4 parts by weight of, and most preferably 3.5 parts by weight of at least one selected from chitosan oligosaccharide, chitosan and algal oligosaccharide; 2-10 parts by weight of, preferably 3 to 9 parts by weight of, more preferably 4-8 parts by weight of, and most preferably 5.5 parts by weight of at least one selected from astragalus polysacharide, and lycium barbarum polysaccharides hawthorn flavone; and 100 parts by weight of probiotics composition which is composed of bacillus subtilis, bacillus coagulans and clostridium butyricum at a weight ratio of 1-3:1-3:1-3, preferably 3:3:3, relatively preferably 3:2:2, more preferably 3: 2:1, and most preferably 3:1:1. Compared with existing synbiotic feed additives, the synbiotic feed additive of the present invention is easier to digest and absorb, and can significantly improve animal immunity and animal health, increase feed utilization, lower feed conversion rates, promote reproduction, improve production performance, improve meat quality and improve breeding environment.

Description

technical field [0001] The invention relates to the technical field of animal feed, especially the technical field of feed additives. Specifically, the present invention relates to a synbiotic feed additive and its preparation method and application. More specifically, the present invention relates to a synbiotic feed additive and its preparation method, animal feed and animal feeding method. Background technique [0002] At present, my country's aquaculture industry is in the process of transforming and developing towards a high-yield, high-quality, efficient, ecological, and safe modern aquaculture mode. There is an urgent need for new green and safe feed additives that can replace or partially replace antibiotics and chemical drugs. In recent years, researchers have focused more on the synergistic effects of probiotics (mainly referring to beneficial live bacteria), traditional Chinese herbal medicines, and functional sugars in animal preventive health care and improveme...
