Abstract

The invention relates to a feed additive, in particular to an oligopolymerization chitosan-astragalus polysaccharide ecological feed additive which comprises Candida utilis, enterococcus faecalis, lactobacillus acidophilus and bacillus subtilis. The feed additive is prepared by culturing the follwing compositions in parts by weight: 1-3 parts of Candida utilis, 1-3 parts of enterococcus faecalis, 1-3 parts of lactobacillus acidophilus and 1-3 parts of bacillus subtilis in a culture medium for 60-72h under the temperature of 28-37 DEG C, wherein the culture medium comprises 1g of agar, 1g of beef extract, 2.5g of yeast extract, 35g of sugar, 1.5g of defoamer, 1g of peptone, 20-50g of oligopolymerization chitosan and 20-50g of astragalus polysaccharide. distilled water is added till the total volume is 1000 ml, and the pH is 6.0, and the mixture is treated by high pressure sterilization for 20m under the temperature of 121 DEG C for later use. The additive can fulfill multiple synergistic function to guarantee the effect and has the advantages of remarkable effect, convenient use and the like.

Description

technical field [0001] The invention relates to a feed additive, in particular to an oligomeric chitosan-astragalus polysaccharide ecological feed additive. Background technique [0002] With the deepening of research on probiotics and biologically active substances, the role of probiotics and active polysaccharides in the prevention and health care of livestock and the improvement of production performance have become increasingly clear. Due to the gradual prohibition of antibiotics and people's concern about food safety, safe feed additives such as probiotics and active polysaccharides will increasingly play a greater role. However, in the past, a single application method was often difficult to achieve the desired effect in use. The development of compound additives will be the development direction of the efficient application of probiotics and active polysaccharides. Contents of the invention [0003] The object of the present invention is to provide a chitosan-oligo...
