Pig feed additive capable of effectively preventing and treating respiratory diseases as well as improving immunity

Abstract

The invention discloses a pig feed additive capable of effectively preventing and treating respiratory diseases as well as improving immunity, belonging to the field of feed additives. The pig feed additive takes Chinese herbal medicines such as fructus forsythiae powder, mixed Chinese herbal medicine polysaccharides, a lonicera japonica leaf extract, radix bupleuri powder, astragalus powder, licorice powder, radix isatidis powder, mint powder, codonopsis powder, rhizoma atractylodis and fructus ligustri lucidi as main raw materials, meanwhile different preparation methods are adopted, and effective components in the Chinese herbal medicines are utilized to the maximum extent. According to the pig feed additive, the compatibility of various Chinese herbal medicines are scientific, and after the pig feed additive is added into the feed, the feed effectively prevents and treats respiratory diseases of pigs, also improves the immunity of the pigs simultaneously, improves the health degree of the pigs, promotes the growth of the pigs, and increases the economic benefits.

Description

technical field [0001] The invention relates to a feed additive for pigs, in particular to a feed additive for pigs which can effectively prevent and treat respiratory diseases and enhance immunity, and belongs to the field of feed additives. Background technique [0002] Porcine respiratory disease complex (PRDC) is a multifactorial disease, which is caused by the interaction of many factors such as bacteria, viruses, mycoplasma, environmental stress, reduced resistance of pigs, and poor feeding and management conditions. The general term for respiratory diseases caused. Porcine respiratory disease is one of the most serious problems plaguing the modern pig industry. In addition to causing direct death of pigs, it also increases treatment costs, reduces feed conversion rates, causes slow growth of pigs, loss of appetite, coughing, dyspnea, delayed The vicious cycle of listing and management has caused serious losses to pig production. The occurrence of porcine comprehensi...

Problems solved by technology

Porcine respiratory disease is one of the most serious problems plaguing the modern pig industry. In addition to causing direct death of pigs, it also increases treatment costs, reduces feed conversion rates, causes slow growth of pigs, loss of appetite, coughing, dyspnea, delayed The vicious cycle of listing and management, etc., caused serious losses to pig production

The occurrence of porcine comprehensive respiratory disease is usually caused by multiple factors. The causes of the disease mainly include: 1. Primary pathogen: often several pathogens exist at the same time, such as porcine reproductive and respiratory syndrome virus, commonly known as "PRRS ", Mycoplasma pneumoniae, porcine circovirus type II, pseudorabies virus, swine influenza virus, Actinobacillus pleuropneumoniae, etc.; 2. Secondary pathogens: After pigs are infected with primary pathogens, due to resistance and immunity The common secondary pathogens are: Streptococcus suis, Haemophilus parasuis, Pasteurella multocida, Toxoplasma, Eperythrozoon, classical swine fever virus and other related respiratory symptoms; 3. Adverse environmental conditions, such as too much stocking density, poor ventilation in the house

[0003] At present, antibiotics are mainly used to treat pig respiratory diseases. Extensive use of antibiotics is likely to produce drug resistance, resulting in the emergence of "super bacteria", etc., and it is also easy to cause food safety problems and affect human health.

At the same time, the epidemic will continue all year round, clinically, the pathogens will be diversified, and the disease will be complicated, which will not only bring many new problems to the prevention and control of the epidemic, but also cause major economic losses.
