Embodiment 1

[0032] A feed formula for preventing and treating pig blue-ear disease with chitosan oligosaccharides, comprising the following components, and the ratio of the formula is calculated in parts by mass: 3% chitosan oligosaccharides, 70% Chinese herbal medicine extracts of astragalus, licorice, forsythia, and epimedium , berberine extract 10%, sweetener 2%, food flavoring agent 2%, carrier maltodextrin 13%.

[0033] When using a kind of chitosan oligosaccharide as a feed formula for preventing and treating pig PRRS, it should be fed with 1 kg / ton full-price feed, mixed material, or added with 500 g / ton drinking water, and used continuously for 7-15 days until the disease occurs Stablize. During the high-incidence period of PRRS, a kind of chitosan oligosaccharide is used as a feed formula for the prevention and treatment of pig PRRS. It is also necessary to do a good job in pig farm immunization prevention, comprehensively implement biosafety prevention and control measures, stre...

Embodiment 2

[0035] A feed formula for preventing and treating pig blue-ear disease with chitosan oligosaccharides, comprising the following components, and the ratio of the formula is calculated in parts by mass: 5% chitosan oligosaccharides, 30% Chinese herbal medicine extracts of astragalus, licorice, forsythia, and epimedium , berberine extract 10%, sweetener 2%, food flavoring agent 2%, carrier maltodextrin 49%.

[0036] When using a kind of chitosan oligosaccharide for the prevention and treatment of pig PRRS feed formula, according to 1 kg / ton of full-price feed, feed with mixing material, or add according to 500 g / ton of drinking water, use continuously for 7-15 days, until the disease Stablize. During the high-incidence period of PRRS, a kind of chitosan oligosaccharide is used as a feed formula for the prevention and treatment of pig PRRS. It is also necessary to do a good job in pig farm immunization prevention, comprehensively implement biosafety prevention and control measures...

Embodiment 3

[0038] When a kind of chitosan oligosaccharide is used for the feed formulation of prevention and treatment of pig blue ear disease, comprise following components, formula ratio is counted by mass fraction: chitosan oligosaccharide 5%, astragalus, licorice, forsythia, epimedium, honeysuckle, fish Herbal extracts of Houttuynia cordata, Banlangen and Bupleurum 50%, berberine extract 10%, sweetener 2%, flavoring agent for food 2%, carrier maltodextrin 31%.

[0039]When using a kind of chitosan oligosaccharide as a feed formula for preventing and treating pig PRRS, it should be fed with 1 kg / ton full-price feed, mixed material, or added with 500 g / ton drinking water, and used continuously for 7-15 days until the disease occurs Stablize. During the high-incidence period of PRRS, a kind of chitosan oligosaccharide is used as a feed formula for the prevention and treatment of pig PRRS.

Abstract

The invention discloses a feed formula of chitosan oligosaccharide for preventing and treating blue ear disease of pigs, comprising the following components in percentage by mass: 3-5% of chitosan oligosaccharide, 30-70% of a Chinese herbal extract, 8-12% of a berberine extract, 2% of a sweetener, 2% of a food flavor, and 9-55% of soluble carrier maltodextrin.The feed formula has the advantages that the components are chemically stable, do not react with other nutrients in the full-price feed, such as trace elements, vitamins and amino acids, are all soluble, can be added to a pig feed or drinking water, and can also exert effects on drinking water for pigs having poor appetite; in the formula, the raw materials are mostly pure natural plant or animal extracts, so the process is simple, the cost is low, and the feed can be well applied to prevention and treatment of the blue ear disease of pigs, improve the immunity and disease resistance of pigs and reduce the costs of feeding and medication, does not have drug resistance or residue, and is conducive to the healthy development of the breeding industry.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding, in particular to a feed formula for preventing and treating pig blue-ear disease with chitosan oligosaccharide. Background technique [0002] Porcine reproductive and respiratory syndrome (PRRSV), also known as "pig blue ear disease", is a disease caused by porcine reproductive and respiratory syndrome virus (PRRSV), characterized by reproductive disorders, premature birth, abortion and stillbirth in sows, piglets and Pigs of different ages, breeds and sexes can be infected. The main target cell of PRRS virus is the mononuclear-macrophage system, which destroys the immune system function of pigs, causes immunosuppression, seriously affects the immune effect of other vaccines, and easily causes mixed or secondary infection of other pathogens. [0003] PRRS virus is an RNA virus that is prone to mutation and can be transmitted vertically to fetuses through the placenta or semen, or t...
