Problems solved by technology

Among them, the excessive use of western medicine has brought great dietary hazards to the consumption of pig products, and drug residues have become one of the main factors affecting the safety of pig products
The early effect of vaccination is better, but multiple vaccinations are required, the operation is troublesome, the cost is high, and it is easy to cause stress reactions in weaned pigs; moreover, the vaccine has high requirements for storage conditions, and it needs to be refrigerated at 2-8°C and kept at room temperature. It will lose its effect after a while
Chinese herbal medicine feed additives are also one of the current research directions, but because there are many types of Chinese herbal medicines, the effects of the same Chinese herbal medicines on different poultry diseases are very different, and the immune effects of Chinese herbal medicines on diseases are extremely limited, so its application also has great potential. certain limitations
Injection of egg yolk antibody is also a relatively common method, but the immune effect of a single injection of egg yolk antibody sometimes cannot meet the actual needs

Embodiment 1

[0043] The anti-swine fever composition of this embodiment includes the following components in parts by weight: 95 parts of anti-swine fever yolk antibody and 2 parts of anti-swine fever transfer factor.

[0044] The feed additive containing the anti-swine fever composition of the present embodiment includes the following components in parts by weight: 95 parts of anti-swine fever yolk antibody, 2 parts of anti-swine fever transfer factor, 0.02 part of thimerosal, 0.2 part of formaldehyde, and 0.05 part of selenium 1 part, 1 part of vitamin C, 2 parts of polyvinylpyrrolidone, 0.5 part of glycine.

[0045] The preparation method of the anti-swine fever feed additive of the present embodiment may further comprise the steps:

[0046] (1) Propagate and inactivate the attenuated strain of CSF to prepare a vaccine, immunize healthy laying hens every 7 days, and immunize three times in total. The second and third immunizations were doubled, and the antibody titer was detected after...

Embodiment 2

[0055] The anti-swine fever composition of this embodiment includes the following components in parts by weight: 97 parts of anti-swine fever yolk antibody, and 1 part of anti-swine fever transfer factor.

[0056] The feed additive containing the anti-swine fever composition of the present embodiment includes the following components in parts by weight: 97 parts of anti-swine fever yolk antibody, 1 part of anti-swine fever transfer factor, 0.01 part of thimerosal, 0.3 part of formaldehyde, and 0.1 part of selenium 1 part, 0.5 part of vitamin C, 1 part of polyvinylpyrrolidone, 1 part of glycine.

[0057] The preparation method of the anti-swine fever feed additive of this embodiment is the same as that of Embodiment 1, the difference lies in the consumption of each component.

Embodiment 3

[0059] The anti-swine fever composition of this embodiment includes the following components in parts by weight: 96 parts of anti-swine fever yolk antibody and 1.5 parts of anti-swine fever transfer factor.

[0060] The feed additive containing the anti-swine fever composition of the present embodiment includes the following components in parts by weight: 96 parts of anti-swine fever yolk antibody, 1.5 parts of anti-swine fever transfer factor, 0.015 parts of thimerosal, 0.25 parts of formaldehyde, and 0.08 parts of selenium parts, 0.8 parts of vitamin C, 1.5 parts of polyvinylpyrrolidone, and 0.8 parts of glycine.

[0061] The preparation method of the anti-swine fever feed additive of this embodiment is the same as that of Embodiment 1, the difference lies in the consumption of each component.

Abstract

The invention discloses a composition for resisting swine fever, a feed additive, and a preparation method and use of the feed additive. The composition comprises, by weight, 95-97 parts of a swine fever-resistant yolk antibody and 0.9-2.1 parts of a swine fever-resistant transfer factor. The feed additive comprises, by weight, 95-97 parts of the swine fever-resistant yolk antibody, 0.9-2.1 parts of the swine fever-resistant transfer factor, 0.01-0.02 parts of an antiseptic, 0.2-0.3 parts of an inactivator, 0.05-0.1 parts of selenium, 0.5-1 part of vitamin C, 1-2 parts of polyvinylpyrrolidone and 0.5-1 part of glycine. Through compounding of the swine fever-resistant yolk antibody and the swine fever-resistant transfer factor, the feed additive can substantially improve swine fever prevention and treatment effects and has the advantages of good specificity, long preservation time at a normal temperature, high antibody titer and good biological activity.

Description

technical field [0001] The invention relates to a composition for resisting swine fever, and also relates to a feed additive containing the composition, a preparation method and application thereof, and belongs to the field of feed additives. Background technique [0002] With the development of society and the improvement of people's living standards, more and more people are turning their attention to food safety issues. The pig industry occupies a relatively large share in my country's breeding industry. In 2009, Henan Province alone produced 4.1032 million tons of pork. From this, we can know that my country's annual demand for pork is very large. However, as the demand for pork increases year by year, more and more problems appear in the process of raising pigs. Among them, swine fever is an acute infectious disease, which has caused huge economic losses to the pig industry. [0003] Classical swine fever, commonly known as "rotten intestinal fever", is an acute, febri...
