Embodiment 1

[0029] The production method of the high-yielding milk cow feed yeast culture additive comprises: common brewer's yeast saccharomycescerevisiae, the rejuvenation of brewer's yeast by introducing the brewer's yeast under the condition of aseptic operation technique, and carrying out under the condition of aseptic operation Brewer's yeast is expanded and cultivated, fermented, and dried to make finished products through a granulator.

Embodiment 2

[0031] The preparation method of the high-yield milk cow feed yeast culture additive described in embodiment 1, the rejuvenation of described bacterial classification: the test tube bacterial classification that preserves is transferred to the test tube that the sterilized solid medium is housed using aseptic technique cultured at a constant temperature of 30°C for 3-5 days; stored at 4°C, and transplanted once every 4-5 months.

[0032] The expanded culture of the strains: under the condition of aseptic operation, carry out the expanded culture of brewer's yeast, inject sterile 0.9% physiological saline into the cultured test tube, shake it to make a bacterial suspension, and then inoculate it into a 1L-capacity In an Erlenmeyer flask filled with 300ml of liquid medium, culture in a constant temperature shaking incubator at 30°C and 180r / min for 36h.

Embodiment 3

[0034] In the preparation method of the high-yield milk cow feed yeast culture additive described in embodiment 1 or 2, the solid medium is prepared by first mixing corn stalks, brewer's grains and cornmeal in a ratio of 20:75:5, and then mixing them The mixture was pulverized to 60-80 mesh, then fully mixed with water at a ratio of 1:1, put into a sterilizing pot at 121°C for 30 minutes, and finally taken out and cooled in a natural state.

Abstract

The invention relates to feed yeast culture additives, the preparation method and application thereof for high producing dairy cows, which aims to overcome the defects that the antibiotic additives have poor influence on the quality and taste of animal products, and the safety problems are caused due to drug resistance and drug residue, which causes the application of the antibiotic additives in animal husbandry production to be limited greatly. The feed yeast culture additives comprise Saccharomyces cereviseae, and the preparation method comprises the following steps of rejuvenating the introduced saccharomyces cereviseae under the aseptic processing technical condition, conducting amplification culture of saccharomyces cereviseae under the aseptic processing condition, fermenting, drying, and then fabricating a finished product through a pelletizer. The feed yeast culture additives are used for feed additives.

Description

Technical field: [0001] The invention relates to a feed additive for improving the nutrition of ruminants, in particular to a preparation method and application of a high-yield milk cow feed yeast culture additive. Background technique: [0002] For nearly half a century, antibiotics have played a huge role in the development of animal husbandry; however, with the improvement of people's awareness of food safety, the adverse effects of antibiotic additives on the quality and flavor of animal products, as well as the safety of drug resistance and drug residues Problems arise thereupon, making its application in animal husbandry production very limited; it is imperative to seek natural green feed additives that are non-toxic, non-residual and non-polluting. Invention content: [0003] The purpose of the present invention is to provide a kind that can be directly added to the feed, can stabilize the balance of microbial strains in the rumen, increase the concentration of the ...
