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

Abstract

The invention discloses a feed additive for anti-porcine viral disease, a preparation method and application thereof, comprising the following components in parts by weight: 2-5 parts of yolk antibody freeze-dried powder for anti-porcine viral disease, 5-10 parts of astragalus polysaccharide , Angelica polysaccharide 5‑10 parts, wolfberry polysaccharide 10‑20 parts, licorice polysaccharide 9‑31 parts. The anti-porcine viral disease feed additive of the present invention is a composite polysaccharide composed of anti-porcine viral disease egg yolk antibody freeze-dried powder and polysaccharides composed of astragalus polysaccharide, angelica polysaccharide, wolfberry polysaccharide and licorice polysaccharide, and can be added to daily feed. Improve the body's immunity and disease resistance. Experimental results show that after adding the feed additive of the invention, the effect of preventing porcine viral diseases is significantly improved, which is obviously better than the effect of adding egg yolk antibody freeze-dried powder or complex polysaccharide alone.

Description

technical field [0001] The invention relates to a feed additive for resisting porcine viral diseases, and also relates to a preparation method and application of the feed additive, belonging to the field of feed. 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. Pork is the main meat product eaten by Chinese residents, and the amount of pork raised in our country is relatively large. However, due to various conditions, the spread of porcine viral diseases is more common. [0003] At present, there are many ways to prevent and treat porcine viral diseases, mainly using western medicine, vaccination and Chinese herbal medicine. 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 ea...
