Embodiment 1

[0032] Embodiment 1 Composite microbial feed additive for piglets

[0033] Strains: a strain of Lactobacillus acidophilus, a strain of Streptococcus faecalis, a strain of Lactobacillus bulgaricus, a strain of Pediococcus lactis;

[0034] Fermentation: Fermentation liquid is obtained by single-strain fermentation; the initial pH of the fermentation medium is controlled at 5-7; the culture temperature is controlled at 35-40°C; the culture time is subject to the pH 3-6 at the end of fermentation;

[0035] After the fermentation, Lactobacillus acidophilus, Streptococcus faecalis, Lactobacillus bulgaricus, and Pediococcus lactis respectively take all the fermentation broths and concentrate them by centrifugation. After the concentration, add skimmed milk powder, lactose powder, and trehalose with a mass ratio of 20% to mix The protective agent is mixed evenly and then freeze-dried to make a high-concentration single-strain bacterial powder; it is made according to the following for...

Embodiment 2

[0045] Example 2 Composite microbial feed additive for chicks

[0046] Strains: one strain of Lactobacillus acidophilus, one strain of Lactobacillus rhamnosus, one strain of Saccharomyces cerevisiae;

[0047] Fermentation: The fermentation broth is obtained by fermentation of a single strain; the initial pH of the fermentation medium is controlled at 5-7; the cultivation temperature is controlled at 30-40°C; the cultivation time is based on the pH of the fermentation end point of 3-6;

[0048] After the fermentation, Lactobacillus acidophilus and Lactobacillus rhamnosus take all the fermentation broth and concentrate them by centrifugation, take the concentrated bacteria sludge and add skim milk powder, lactose powder, trehalose mixed protective agent with a mass ratio of 20%, and emulsify evenly Freeze drying was carried out. Saccharomyces cerevisiae fermented liquid is centrifuged and concentrated, and the concentrated bacteria sludge is added with a mass ratio of 30% treha...

Embodiment 3

[0057] Example 3 Compound microbial feed additive for calves

[0058] Strains: one strain of Lactobacillus acidophilus and one strain of Saccharomyces cerevisiae.

[0059] Fermentation: The fermentation broth is obtained by single-strain fermentation; the initial pH of the fermentation medium is controlled at 5-7; the culture temperature is controlled at 30-40°C; the culture time is subject to the pH 3-6 at the end of fermentation;

[0060] After the fermentation, Lactobacillus acidophilus takes all the fermentation broth and concentrates it by centrifugation. The concentrated bacteria sludge is added with 20% by mass skimmed milk powder, yeast powder and sodium glutamate mixed protective agent, and then freeze-dried after being evenly emulsified. Saccharomyces cerevisiae fermented liquid is centrifuged and concentrated, and the concentrated bacteria sludge is added with a mass ratio of 30% trehalose and maltodextrin mixed protective agent, mixed evenly and then spray-dried to...

Abstract

The invention relates to a composite microorganism livestock and poultry feed additive and manufacturing method thereof, belonging to the feed technology field. The invention discloses a composite microorganism livestock and poultry feed additive, which is characterized in comprising composite bacterium powder in 1.0-15% of total mass protion; wherein, the composite bacterium powder is compatible of any two or more of the lactobacillus, yeast, pediococcus acidilactici and fecal streptococcus. the strains in the microorganism feed additive of the invention can symbiose to each other, which is favorable to performance their biological activities, and can keep enough shelf life and live bacteria quantity. The invention also achieves the advantages of controlled production process, lower cost and stable product quality.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a compound microbial feed additive for livestock and poultry and a preparation method thereof. Background technique [0002] As a special feed additive, microbial feed additives promote the growth of farmed animals through the physiological metabolism of microbial strains, reduce the use of antibiotics and other drugs, improve the quality of farmed animals, thereby improving breeding benefits and realizing green farming. Therefore, the selection of highly active bacterial strains and good production technology is the focus of making microbial feed additives. The selection of highly active strains is the basic work that must be done for microbial products, and the biological functions of the strains used directly affect the effect of the product. According to the use of the product, the corresponding bacterial strain should be selected. After in vitro tests, it shows: such as high e...
