Abstract

The invention relates to a wild jujube seed extract which is prepared by the following method: crushing wild jujube seeds, screening, soaking with ethanol to extract, after removing alcohol, adding water, uniformly stirring, leaching with aqueous n-butylalcohol, lastly concentrating and airing. The wild jujube seed extract of the invention can be prepared into oral liquid, granules, injection or freeze-drying powder injection through routine techniques. The wild jujube seed extract can be used prepare medicament compositions preventing poultry mycoplasma, Escherichia coli, brusal disease virus, avian H9 influenza virus disease, makes up for loss caused by poor preventing effect of existing bacterin in our country, substitutes bacteriophage to prevent and treat poultry resistant virus disease to control prevalence of infectious disease and solve a problem of bacteriophage residue in foods, thus guaranteeing food security and promoting export competitive ability of animal products.

Description

technical field [0001] The invention relates to an extract of Jujube Semen capable of preventing poultry mycoplasma, Escherichia coli, chicken bursal disease and avian lymphoid leukemia new subtype virus diseases, as well as its preparation method and application. Background technique [0002] Since the beginning of the 21st century, major livestock and poultry diseases have continued to break out all over the world, which not only seriously hindered the healthy development of animal husbandry, but also caused a series of public health emergencies. Major epidemics such as coccidiosis and foot-and-mouth disease have caused great harm to people's health and social stability. Therefore, the research and creation of new biological veterinary drugs has become a major national demand to ensure the development of my country's animal husbandry, maintain people's health and life safety, maintain social stability and promote economic development.
