Example Embodiment

[0019] Example 1: Using culture-free technology combined with statistical methods to screen the dominant bacteria in the rumen of high milk-yielding dairy cows, use pure culture technology to obtain pure strains of dominant bacteria, and combine them into a microecological preparation through fermentation and culture compatibility; prepare according to the following steps :

[0020] (1) Sequencing: DNA from rumen juice of Holstein cows was extracted for PCR amplification, and the components of the microbial community in the rumen of cows were obtained by high-throughput sequencing and taxonomic analysis of the genome sequencer; the said genome sequencer expressed Miseq in English;

[0021] (2) Screening: The dominant bacteria in the rumen of high-producing dairy cows, namely Bacteroides and rumen cocci, were screened out through statistical analysis;

[0022] (3) Isolation and purification of bacterial species: extract the rumen fluid of dairy cows, cultivate rumen microorganisms by ...

Abstract

The present invention discloses a micro-ecological preparation for improving milk yields of dairy cows, and belongs to the preparation for improving the milk yields of the dairy cows. The micro-ecological preparation uses a method combining statistical methods with culture-independent technology to screen dominant bacteria in rumens of high-yielding dairy cows; pure strains are obtained from the dominant bacteria by using pure culture technology; and the micro-ecological preparation is prepared through fermenting, culturing, combining and mixing the pure strains. The micro-ecological preparation is prepared by following specific steps: (1) sequencing, (2) screening, (3) separating and purifying strains, (4) culturing, (5) fermenting (6) mixing and (7) packaging. The micro-ecological preparation contains Bacteroidaceae and Ruminococcus helpful for decomposing polysaccharide and cellulose, can improve Bacteroidaceae and Ruminococcus contents in rumen bacteria of the high-yielding dairy cows in order to ensure the advantage position and improve the utilization of the cellulose and the polysaccharide, thus improving absorption and utilization of feed nutrient components for the dairy cows, increase the milk yields and bring economic benefits. The Bacteroidaceae can help the host absorb the polysaccharide, improve nutrition utilization rates and host's immunity, and maintain gastrointestinal micro-ecological balance. The micro-ecological preparation has a strong pertinence and specificity.

Description

technical field [0001] The invention relates to a preparation for increasing milk production of dairy cows, in particular to a microecological preparation for increasing milk production of dairy cows. Background technique [0002] Microecological preparation is a green and safe feed additive with no toxic side effects and no drug resistance. It can adjust or maintain the microecological balance in the gastrointestinal tract of animals, enhance the body's immunity, and promote the digestion and absorption of nutrients. [0003] At present, the feed microecological preparations commonly used by ruminants at home and abroad include bacteria such as lactic acid bacteria (Lactobacillus, Bifidobacterium, etc.), Bacillus (Bacillus subtilis, Bacillus cereus, etc.), Aspergillus (Aspergillus niger, etc.) , Aspergillus oryzae) and yeasts (beer yeast, and petroleum yeast and their cultures) and other single and complex bacterial preparations. These probiotics sold in the market are not...
