Eu-commin intragastric administration agent for cows and preparation method thereof

Abstract

The invention provides an eu-commin intragastric administration agent for cows and a production method thereof. The production method comprises the following steps: dry eucommia leaves are extracted twice continuously, and each time extraction time is 1.5-2 h; an extract liquid is subjected to stilling and precipitating by a natural clarifying agent, supernate is pumped out, lower suspension is centrifugalized, and filtrate is mixed with the supernate; an ultrafiltration membrane is separated, then a dialyzate over-wind type nanofiltration membrane is separated and condensed, dialyzate is pumped in an extracting tank for recycling, and trapped fluid is condensed till the concentration is 20-30%; nanofiltration trapped fluid is pumped in a high-temperature instant sterilization machine for sterilization, and enters into a filling machine for filling under the sterile condition. The eu-commin intragastric administration agent can enhance the immunity of the organism of the cows, effectively controls the recessive mastitis and the clinical mastitis, can reduce the somatic cell counts of the cows remarkably, improves the tendency of milk production, and has no remarkable influence on the fermentation function of cow rumen, the butter-fat content and the milk protein rate. Meanwhile, the eu-commin intragastric administration agent is an aqueous solution, is convenient to use, and has no side effects.

Description

technical field [0001] The invention relates to pharmaceutical products for animals, and in particular provides a cow-specific eucommia gavage agent for preventing and controlling cow mastitis and somatic cell count and a preparation method thereof. Background technique [0002] Cow mastitis is a common disease in dairy farming. Scientific research shows that one-third of the 200 million dairy cows in the world suffer from mastitis, causing an annual loss of about 30 billion U.S. dollars, and the annual loss in my country is more than 10 billion yuan. The symptoms of dairy cow mastitis are inflammation of the udder parenchyma and interstitium. The etiology is mostly caused by mechanical stimulation, infiltration of pathogenic microorganisms, and chemical and physical damage. The symptoms include clinical mastitis and recessive mastitis. Various degrees of swelling, pain, reduced milk production, milk denaturation, somatic cell count surge, etc., seriously affect the health ...

Problems solved by technology

As it is a feed additive, long-term adaptation will inevitably have adverse effects on the longevity of dairy cows

If used alone as a drug, it is a powder, which is inconvenient to use by gavage
