Problems solved by technology

Due to factors such as the primary or secondary pathogens of porcine respiratory disease syndrome in different regions and pig farms and bacterial resistance, so far, there are still no ideal prevention and control measures at home and abroad.

Embodiment 1

[0040] Porcine reproductive and respiratory syndrome virus, swine fever virus, porcine circovirus type 2, and porcine pseudorabies were detected by collecting diseased pigs from a certain pig farm in Yiliang County, Kunming City, Yunnan Province with symptoms of porcine respiratory disease syndrome. Viruses, according to statistics, the main causative virus of porcine respiratory disease syndrome in this farm is the mixed infection of classical swine fever virus and porcine pseudorabies virus.

[0041] According to the formulated implementation plan, 67 breeding pigs in the pig farm were first purified of classical swine fever virus and porcine pseudorabies virus, and carried out comprehensive prevention and control of porcine respiratory disease syndrome. After 4 years of implementation, the pig farm has achieved obvious economic and social benefits:

[0042] 1. The production performance of breeding pigs has been improved, and the litter size has increased from 10 to 13; the...

Embodiment 2

[0048] Taking comprehensive prevention and control measures for the porcine respiratory disease syndrome that occurred in a self-propagating and self-raising pig farm of a Yunnan Ecological Technology Co., Ltd., and purifying the main pathogenic virus disease swine fever, significant economic benefits and prevention and control effects have been achieved:

[0049] 1. The production performance of breeding pigs has been improved, and the number of litters has increased from 10 to 10.5; the reproductive failure rate has decreased by 2%; the survival rate of weaned piglets has increased from 88.7% to 90.1%.

[0050] 2. The incidence of porcine respiratory diseases dropped from 35% to 13%.

[0051] 3. Gradually reduce the cost of disease prevention and control every year, saving 30,000 yuan per year in drug costs.

[0052] 4. During the project period, the pig farm achieved economic benefits of 840,000 yuan.

[0053] 5. Promote the healthy development of the two surrounding pig f...

Embodiment 3

[0055] Comprehensive prevention and control measures were taken for the porcine respiratory disease syndrome that occurred in a breeding company in Kunming, and the main pathogenic virus disease swine pseudorabies was purified, which achieved significant economic benefits and prevention and control effects:

[0056] 1. The production performance of breeding pigs has been improved, and the litter size has increased from 7 heads / little to 8.8 head / litter; the reproductive failure rate has decreased by 5%; the survival rate of weaned piglets has increased from 86% to 89%.

[0057] 2. The incidence of pig respiratory diseases dropped from 43% to 23%.

Abstract

A method for controlling porcine respiratory disease complex comprises the steps: controlling porcine respiratory disease complex at the source, namely major viral pathogens; performing epidemiological research on the major pathogens of porcine respiratory disease complex at a pig farm; checking out the major pathogens; purifying the major viral pathogens; scientifically using vaccines to protect susceptible pigs; sampling epidemical materials from the pigs developing secondary bacterial infections for bacterial culture; running a drug sensitivity test; using sensitive drugs for treatment; enhancing comprehensive control on the pig farm; and achieving the control on porcine respiratory disease complex for homebred pig farms.

Description

technical field [0001] The invention relates to a method for preventing and controlling porcine respiratory disease syndrome. Background technique [0002] Porcine respiratory disease syndrome is a new type of respiratory disease that has appeared in pig diseases in recent years. At the 15th International Swine Disease Conference held in Manchester, England in 1998, the concept of porcine respiratory disease syndrome was proposed. Statistics show that porcine respiratory disease syndrome is one of the most important diseases that plague pig production. The pathogens causing porcine respiratory disease syndrome are multi-cause (mainly including porcine reproductive and respiratory syndrome virus, classical swine fever virus, porcine circovirus type 2, porcine pseudorabies virus, mycoplasma pneumoniae and various bacteria), varied (different regions and pig farms have different pathogens), relatively random (due to different pig farm management, pig herd nutrition, and pig im...
