Problems solved by technology

[0002] Porcine comprehensive respiratory disease commonly occurs in pig farms. Although the overall mortality rate is not high, the sick pigs suffer from loss of appetite, reduced feed utilization, coughing, dyspnea, and reduced growth rate, which seriously affect the economic benefits of the pig farm.
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 commonly used for treatment, which is easy to produce drug resistance. The abuse of antibiotics leads to the emergence of "super bacteria", the aggravation of mycotoxin hazards, the pollution of the breeding environment, and the lack of attention to the establishment of a biosafety system, etc.
As a result, the epidemic has continued throughout the year, clinically, the pathogens have diversified, and the symptoms have become more complicated, which not only brings many new problems to the prevention and control of the epidemic, but also causes major economic losses

Abstract

The invention discloses a Chinese herbal medicine feed additive for effectively controlling comprehensive respiratory diseases of pigs, and belongs to the technical field of feed additives. The Chinese herbal medicine feed additive takes Chinese herbal medicines including cortex acanthopanacis, platycodon grandiflorum, common cephalanoplos herbs, rhizoma cyperi, asparagus cochinchinensis, liquorice and the like as main raw materials, and is respectively prepared by using different preparation methods; the effective components in the Chinese herbal medicines are extracted to the utmost extent and are scientifically compounded with carefully prepared cordyceps sinensis mycelium powder, so that the Chinese herbal medicine feed additive can be prepared; and after the Chinese herbal medicine feed additive is added into feed, the immunity of the pigs easting the feed with the additive can be effectively improved, the primary pathogens and the secondary pathogens which can cause the comprehensive respiratory diseases of the pigs are remarkably inhibited, and the comprehensive respiratory diseases of the pigs can be effectively prevented and treated by the Chinese herbal medicine feed additive. Furthermore, effective active substances in the components of the composition can effectively improve the immunity of the pigs, improve the health degree of the pigs, promote the growth of the pigs and improve the economic benefits.
