Problems solved by technology

Although protozoa have a strong decomposing effect on cellulose, they will also swallow a large number of bacteria, and the increase of protozoa will reduce the content of propionic acid in the rumen, and propionic acid is the main source of glucose for ruminants. Therefore, the proportion of protozoa If it is too high, it will not be able to guarantee the animal's demand for energy, and it will also cause diarrhea problems caused by the imbalance of flora in the rumen of sheep
None of the existing sheep feed additives can solve this problem

Embodiment 1

[0021] A microbial flora additive for sheep feed, characterized in that the additive includes the following quantitative ratio composite flora: Bifidobacterium bifidum: Saccharomyces cerevisiae: Bacillus coagulans: Bacillus subtilis: Enterococcus faecalis= 58:26:7:7:1. The microbial flora additive also includes auxiliary materials, and the auxiliary materials include: bran, starch, oligosaccharides and starch.

[0022] The preparation method of the above-mentioned microbial flora additive is as follows: first produce the fermentation liquid of Bifidobacterium bifidum, Saccharomyces cerevisiae, Bacillus coagulans, Bacillus subtilis and Enterococcus faecalis, and then convert the ratio of the fermentation liquid into the fermentation liquid according to the number ratio according to the strain density , and mix the fermented liquid according to the ratio after conversion, and dry it with auxiliary materials at low temperature, crush and sieve to make a solid. Wherein: the produ...

Embodiment 2

[0024] The microbial flora additive described in embodiment 1, wherein the number of live bacteria of the composite flora is 2.0 × 10 8 cfu / g. The finished product is prepared by the method described in Example 1, and the finished product is added to the feed for raising sheep with the addition of 0.2%, drinking and feeding, three sheep farms are investigated through 1 month, compare 50 The pH value of the rumen of a sheep dropped from 6.13 to 5.78 before and after the treatment with the compound flora, further inhibiting harmful microorganisms and achieving the beneficial effects described in the present invention.

Embodiment 3

[0026] The microbial flora additive described in embodiment 1, wherein the viable count of composite flora is 1.0 × 10 9 cfu / g. The finished product is prepared according to the method described in Example 1, and the finished product is added to the feed for raising sheep with an additive amount of 0.3%, mixed and fed, and 30 sheep are randomly selected in a sheep farm with about 600 sheep. , as the experimental group and control group of this embodiment, respectively, and compare the changes in the number of lactic acid bacteria, yeasts, spores, and ciliates (the main group of protozoa) in the rumen of sheep half a month later (Table 1). It can be seen from Table 1 that after half a month of investigation, the lactic acid bacteria, yeast and spores in the rumen of the sheep in the control group were almost unchanged, and the number of protozoa increased slightly; About 5.5 times and 6.5 times of the original after 1 month respectively, the number of ciliates has decreased b...

Abstract

The invention discloses a microbial flora additive used for a sheep feed. The microbial flora additive is characterized by comprising the components of complex microbial floras, bifidobacterium bifidum, brewer's yeast, bacillus coagulans, bacillus subtilis and enterococcus faecalis according to the ratio of (56-58):(24-27):7:7:1, wherein the viable count of the complex microbial floras is between 2.0*10<8>cfu / g and 1.0*10<9>cfu / g. The microbial floras regulate the micro-ecological balance in the intestinal tract through the collaborative action, the use of medicines like antibiotics is avoided, the product is more environmentally friendly, the cost is low, and the microbial flora additive has an excellent application prospect.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a microbial flora used for raising sheep and a preparation method thereof. Background technique [0002] In recent years, my country has attached great importance to the development of herbivorous livestock, especially the development of cattle and sheep. However, the growth of cattle and sheep is inseparable from feed, and feed additives are even more indispensable in feed. Although the amount of feed additives is small, it has a huge effect. It has multiple functions such as supplementing or balancing feed nutrition, preventing diseases, promoting the growth of sheep, ensuring the quality of feed and increasing the output of sheep products. The scientific use of feed additives can not only effectively increase the output of sheep products, but also improve the utilization rate of feed, save feed, reduce costs, and achieve the purpose of increasing production and income. ...
