Method for preparing high-activity probiotic preparation for livestock breeding

Abstract

The invention provides a method for preparing a high-activity probiotic preparation for livestock breeding. Five bacterial-propagation pure cultures including bacillus subtilis 35-45%, bifidobacterium 15-25%, bear yeast 20-30%, lactobacilli 3-9% and photosynthetic bacteria 6-12% by mass are mixed into a bacterial mixed liquid last two hours before fermentation. Rice bran 30-38%, wheat bran 25-32%, soya bean meal 6-10%, molasses 2-5%, water 23-29%, saccharifying enzyme 0.07-0.13% and bacterial mixed liquid 0.8-1.2% by mass are evenly paved in an independently-closed fermenting tank adjustable in temperature. The method for preparing the high-activity probiotic preparation for the livestock breeding creates a three-phase bacterial-propagation technology including activation, liquid propagation and solid fermentation production. The total amount of viable bacteria is increased to the most extent, the stability of a probiotic preparation product is improved, and the probiotic preparation product can be preserved for 9-12 months under the normal-temperature condition.

Description

technical field [0001] The invention relates to a preparation method of a highly active probiotic preparation for animal husbandry, and belongs to the technical field of preparation methods of probiotic preparations. Background technique [0002] In the 1950s, it was discovered that adding low-concentration antibiotics to feed could significantly promote the growth of livestock and poultry. Since then, the use of antibiotics as feed additives has occupied a very important position. With the deepening of people's understanding of antibiotics, the hidden disadvantages behind the huge economic benefits brought by antibiotic additives have gradually been discovered: long-term use of antibiotics will lead to bacterial resistance, and will also cause the decline in the immunity of livestock and poultry, causing livestock and poultry Poultry endogenous infection and superinfection; antibiotics will cause residues in livestock products that directly threaten human health. Misuse ma...
