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 a composition for resisting canine parvovirus, freeze-dried powder, and a preparation method and use of the freeze-dried powder, and belongs to the technical field of veterinary feed additives. The composition comprises, by weight, 95-97 parts of a canine parvovirus-resistant yolk antibody and 1-5 parts of a canine parvovirus-resistant transfer factor. The freeze-dried powder comprises, by weight, 95-97 parts of the canine parvovirus-resistant yolk antibody, 1-2 parts of the canine parvovirus-resistant transfer factor, 0.2-0.3 parts of an inactivator, 0.01-0.02 parts of an antiseptic and 2.05-3.6 parts of a heat-resistant freeze-dried protective agent, and has the advantages of low preservation conditions, long preservation time, high antibody titer and good biological activity. Through combined use of the canine parvovirus-resistant transfer factor and the canine parvovirus-resistant yolk antibody, the freeze-dried powder has effects of preventing and treating canine parvovirus-caused diseases, improves dog immunity and survival rate, is convenient for use and has a low 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...
