Preparation method of probiotic feed additive

Abstract

The invention discloses a preparation method of a probiotic feed additive. In the method, liquid spawns containing a variety of microbial communities, solid culture media, molasses and urea are mixed and prepared into the probiotic feed additive via solid fermentation, drying and pulverization; the probiotic feed additive prepared by the method can be added into livestock and poultry feed to promote the growth of the livestock and poultry, enhance the organism immunity of the livestock and poultry and regulate intestinal ecological balance; meat, egg and milk products have no chemical residues, which can meet the requirements of green food; the undesirable odor and ammonia odor of the manure of the livestock and poultry are reduced, flies, maggots and other pests are reduced, and the culture environment is improved.

Description

technical field

[0001] The invention relates to a preparation method of a feed additive. In particular, it relates to a preparation method of a probiotic feed additive. Background technique

[0002] At present, most of the widely used feed additives are medicated feed additives. Anti-infective drugs such as antibiotics are often used, and the use cost is high. It kills pathogenic bacteria and also kills the normal flora of the animal intestine, and it is easy to produce drug residues, which makes the quality of animal products poor. Reduced, coupled with continuous single use of a certain antibiotic will cause pathogens to develop resistance.

[0003] In order to overcome the shortcomings of pharmaceutical additives, research and development of probiotic feed additives has been started at home and abroad. Most of the probiotic feed additives that have been publicly used are single species, and most of them are prepared by liquid fermentation, which requires complicated pro...

Embodiment 1

[0020] A preparation method of a probiotic feed additive is prepared by mixing liquid strains containing multiple microorganisms, a solid culture medium, molasses and urea through solid fermentation, drying and crushing; wherein: the liquid strains account for the dryness of the solid medium. 10% of the weight of the solid medium, molasses accounts for 15% of the dry weight of the solid medium, and urea accounts for 1% of the dry weight of the solid medium;

[0021] The percentage of viable bacteria of various microbial species in the liquid bacterial liquid is:

[0022] Bacillus subtilis 20%; Bifidobacterium 15%; Aspergillus niger 15%; Yeast 20%; Photosynthetic bacteria 15%; Enterococcus faecalis 15%;

[0023] The solid medium is prepared by mixing the following raw materials by weight percentage:

[0024] Corn flour 20%; bran 30%; calcium carbonate 1%; soybean meal 5%; soy sauce lees 10%; vinegar residue 34%.
