Microbial preparation for controlling and eliminating mastitis pathogenic bacterium and application thereof

Abstract

The invention discloses a microbial preparation for controlling and eliminating mastitis pathogenic bacterium and application thereof. The microbial preparation for controlling and eliminating the mastitis pathogenic bacterium is prepared from Bdellovibrio bacteriovorus telotroch. Through detection, the microbial preparation can effectively eliminate common mastitis pathogenic bacterium of milk cows, including colibacillus, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus agalactiae and the like existing in the environment. Compared with Bdellovibrio bacteriovorus leech plastid, the microbial preparation has the weaknesses of fussy preparation and difficult storage, but has the advantages of rapid effect and strong activity by using the Bdellovibrio bacteriovorus telotroch to control and eliminate the mastitis pathogenic bacterium. The Bdellovibrio bacteriovorus telotroch has no side or toxic effect for the milk cows so that the microbial preparation prepared from the Bdellovibrio bacteriovorus telotroch is suitable for large-scale industrial culture of milk cows, provides guarantee for green processing and production of the milk cows and provides a new approach for controlling and eliminating the mastitis pathogenic bacterium of the milk cows.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to a microbial preparation for controlling and eliminating mastitis pathogenic bacteria and its application. Background technique [0002] Dairy cow mastitis (also called mastitis) is one of the diseases with the highest incidence and the most serious losses in dairy farming. According to statistics, clinical mastitis accounts for 21% to 23% of the total incidence of dairy cows, and recessive mastitis is more common in dairy herds, with an incidence rate as high as 50%. The occurrence of mastitis in dairy cows has a serious impact on the yield and quality of milk, and has caused extremely serious economic losses to the development of cattle breeding. [0003] Pathogen infection is the main cause of mastitis, including bacteria, fungi, viruses, mycoplasma, etc. The main pathogenic bacteria are bacteria, the common ones are Staphylococcus aureus, Escherichia coli, Streptococcus and mycopla...

Problems solved by technology

However, these conventional disinfectants are in direct contact with organic matter such as cow dung and feed residues, causing the disinfectant to be consumed by a large amount of organic matter, hindering the drug's effect, greatly reducing the killing effect of the drug on pathogenic microorganisms, and requiring a large amount of disinfection. drug

Conventional disinfectants are chemically sterilized. If they are sprayed on the cows, they will pose a threat to the health of the cows. They may also pollute the milk and remain in the milk to affect the quality of the milk.
