Aseptic powder injection used for breasts of cow with mastitis and preparation method thereof

Abstract

The invention provides a germ-free powder injection for treating cow mammitis and its preparing process, wherein the injection comprises lactic acid streptostacin to replace antibiotics in cow mammitis treatment, as a result, no unwanted residual to human body is formed in milk. The injection also has the advantages of controllable quality, better stability and convenience in transportation.

Description

technical field [0001] The invention relates to a medicine for treating cow mastitis, in particular to a sterile powder injection preparation for treating cow mastitis and a preparation method of the sterile powder injection preparation. Background technique [0002] Cow mastitis is one of the most common diseases that harm the dairy farming industry. About 50% of dairy cows in the world suffer from various types of mastitis. Affected cows have reduced milk production and quality. The direct economic loss caused by cow mastitis in the United States reaches 2 billion US dollars every year. About 70% of the loss caused by mastitis in dairy cows is the decline in milk production caused by recessive mastitis. In China, the annual loss caused by recessive mastitis alone is at least 135 million yuan. The main cause of mastitis in dairy cows is the infection of the mammary glands with pathogenic microorganisms. Therefore, the current treatment of the disease is based on antibio...

Problems solved by technology

The long-term, extensive and high-dose use of antibiotics in the treatment of cow mastitis has led to a series of adverse consequences

The first is the problem of food public health: after treatment with antibiotics, there is a potential risk of drug residues in milk, which will adversely affect human health; secondly, the increase in drug-resistant strains: pathogenic bacteria develop drug resistance, making mastitis more severe It is becoming more and more difficult to cure, and veterinarians on cattle farms have to increase the dosage of antibiotics, which increases the risk of drug residues; other hazards of drug residues include inhibition of the fermentation process in dairy production, resulting in reduced product yield and quality

However, the solution has the disadvantages of inconvenient transportation, increased weight and increased transportation costs.
