Composite microorganism additive agent for milk cattle feed stuff and method of preparing the same

Abstract

The invention discloses a compound microorganism additive for milk cow feed. The microorganism additive consists of fermentation product mixture of natto bacillus subtilis, enterococcus faecium and saccharomyces cerevisiae, wherein the total number of bacteria is more than 10<9>cfu / g. Long-term repeating animal experiments show that three microorganisms in the compound microorganism additive can develop synergy, thereby significantly improving the milk yield of the milk cow, fat percentage in the milk and milk protein yield, significantly reducing the somatic number of the milk cow in lactation period and the disease probability of mastitis and subclinical mastitis, and significantly enhancing the autoimmunity of the milk cow organism. The compound microorganism additive has the advantages of low cost, significant effect and good application and market prospects.

Description

technical field

[0001] The invention relates to a microbial preparation, in particular to a microbial preparation for cows and a preparation method thereof, belonging to the field of microorganisms. Background technique

[0002] Lactic acid bacteria is a general term for a class of bacteria that produce lactic acid by decomposing sugars. This type of preparation is the earliest, most widely used, and has a wide variety. Usually anaerobic or facultative oxygen growth, the disadvantage is that it is not resistant to high temperature, after 5 minutes of treatment at 80 ° C, the loss of 70% to 80%. The loss rate is relatively large during the pellet feed preparation process. However, it is acid-resistant and can still grow when the pH value is 3.0-4.5, and has a certain tolerance to the acidic environment in the stomach. In animals, it prevents and inhibits the invasion and colonization of pathogenic bacteria through biological antagonism and lowering the pH value, degrades ha...
