Problems solved by technology

At present, people use vaccines to immunize canine parvovirus disease. The early effect is better, but multiple vaccinations are required, the operation is troublesome, the cost is high, and it is easy to cause stress reactions in livestock and poultry, and the vaccines have strict requirements for storage conditions. It needs to be refrigerated at low temperature, and it will be invalid at room temperature for a period of time

Abstract

The invention discloses an anti-canine parvovirus composition, freeze-dried powder, preparation method and application, and belongs to the technical field of animal feed additives. The composition is composed of the following components in parts by weight: 95-97 parts of anti-canine parvovirus egg yolk antibody, and 1-5 parts of anti-canine parvovirus transfer factor. The freeze-dried powder is composed of the following components in parts by weight: 95-97 parts of anti-canine parvovirus egg yolk antibody, 1-2 parts of anti-canine parvovirus transfer factor, 0.2-0.3 parts of inactivator, 0.01-0.02 parts of preservative, 2.05 to 3.6 parts of heat-resistant freeze-drying protective agent; it has the advantages of reducing storage conditions, prolonging storage time, high antibody titer, and good biological activity. The combination of anti-canine parvovirus transfer factor and anti-canine parvovirus egg yolk antibody can prevent and treat canine parvovirus The efficacy of the virus disease can improve the immunity and survival rate of the dog, and is convenient to use and low in cost.

Description

technical field [0001] The invention specifically relates to an anti-canine parvovirus composition for a feed additive, and an anti-canine parvovirus freeze-dried powder, and also relates to a preparation method and application of the freeze-dried powder, belonging to the technical field of animal feed additives. Background technique [0002] Dog breeding has developed rapidly in our country in recent years. With the improvement of people's living standards, the pursuit of spirituality has become more advanced. Dogs are human partners and the most demanded animal for pets. With the rapid development of the dog industry, the ensuing canine parvovirus disease is gradually increasing. [0003] Canine parvovirus is a viral disease caused by canine parvovirus (CPV). In 1978, Kelly in Australia and Thomson in Canada isolated canine parvovirus from the feces of dogs suffering from enteritis at the same time. Since the virus was discovered, it has been prevalent all over the world...
