Problems solved by technology

In the 21st century, my country's vaccines are a century of rapid take-off. Not only have a large number of fire-fighting vaccines and attenuated vaccines for bacteria and viruses been developed, but also genetically engineered vaccines have been produced, which have made great contributions to the development of animal husbandry. However, in recent years my country's vaccines are facing new and huge difficulties in the development. At present, live freeze-dried vaccines account for a considera

Abstract

The invention relates to a freeze-dried vaccine drinking water immune protective agent for chicken and a preparation method thereof. The immune protective agent comprises the following components by weight: 5-10 parts of levamisole hydrochloride, 10-30 parts of mannose, 20-50 parts of lactose, 5-10 parts of n-caprylic acid, and 2-5 parts of Tween-80. The protective agent provided by the invention can regulate water quality, eliminate the interference of ions in water to vaccines, inhibit the combination of calcium ions and sodium ions with vaccines, has very good preventive and protective effects on the influence of various causes on freeze-dried vaccines in water, has no toxic or side effect, also does not produce drug residue, is convenient to use and low in cost, plays a very good role in the use of various freeze-dried vaccines in culture, and is a cheap freeze-dried vaccine protective agent simple to use.

Description

Technical field [0001] The invention belongs to the field of veterinary medicine, in particular to a freeze-dried seedling drinking water immune protective agent for chickens and a preparation method thereof. Background technique [0002] my country is a large breeding country, the amount of livestock and poultry breeding ranks first in the world, accounting for 2 / 3 of the world. In recent years, China's aquaculture has been continuously transforming to scale, intensification and mechanization. With the continuous and healthy development of the breeding industry, the breeding level of chicken farmers is also changing with each passing day. In the 21st century, China’s vaccines are taking off rapidly. Not only have a large number of bacteria and virus fire-fighting vaccines and attenuated vaccines been developed, but also genetically engineered vaccines have been produced, which have made great contributions to the development of animal husbandry. But in recent years China’s vac...
