The incidence of African swine fever is revealed! Pig farmers must read to understand the key to epidemic prevention
Uncover the pathogenic mechanism of African swine flu virus! Pigs just need to read and grasp the essentials of disease prevention.
As we all know, African pigs are just a headache, but African pigs are only a small hidden danger, and no pig farm can prevent its occurrence. Therefore, pig breeding enterprises must grasp the occurrence and development law of African swine disease and carry out prevention and control as soon as possible to reduce their economic losses. This article will have a more comprehensive understanding of the pathogenic law of African swine fever.
Pathogenesis models. 1) Epidemic period: The main epidemic seasons of African swine fever are early spring, late autumn and winter. During this period, farmers should pay close attention to the development and evolution of the disease and take corresponding prevention and control measures.
African swine fever occurs in spring, autumn and winter, and the weather conditions at this stage create favorable conditions for the epidemic of the disease. In early spring, the temperature rises, the body's metabolic ability decreases, the body's resistance decreases, and it is very susceptible to the invasion of epidemics; In autumn, due to the cold, dry climate, the preserved food can breed germs and cause the pig herd to be infected with diseases of the upper respiratory system; In winter, due to the low temperature and high humidity, the air circulation in the pig house is not smooth, which leads to diarrhea and diarrhea in the pigs. Therefore, in autumn and winter, we should do a good job in the monitoring and prevention of epidemic diseases, and formulate corresponding prevention and control measures in a timely manner to ensure the physical condition of pigs.
2) Population: The African swine fever epidemic shows a certain regularity. In general, older pigs are only the first to be infected, while protected animals are late, and fewer pigs are breastfed. In addition, there are differences in the prevalence between breeds, with the first trimester being the most common, followed by empty pregnancy, and the incidence in the third trimester and lactating women is lower than normal.
The occurrence of African swine fever varies greatly among pigs of different ages. African swine fever is a common infectious disease that plays a vital role in disease prevention and prevention. Because sows have a relatively stable immune system during growth, their ability to resist virus invasion is stronger than that of adult pigs; Compared with piglets of other ages, suckling pigs have a certain degree of protection due to lactation and immunization, and the probability of disease is lower.
In addition, the incidence of disease in sows varies during pregnancy. In the first trimester, due to the effect of progesterone, the body's immune function is low, and the immune function is weakened, and it is very susceptible to the invasion of viruses; However, due to the absence of progesterone, the immune function of empty sows has gradually improved, and the probability of disease has been reduced; In the third trimester, with the gradual improvement of the body's immunity and the development of the fetus, its resistance to various viruses is relatively high; The results showed that the immune function of lactating sows had basically recovered, the resistance to viral diseases had decreased significantly, and the infection rate had decreased significantly.
To this end, farmers should formulate targeted disease prevention measures according to the characteristics of African swine fever, according to their different age groups and different physical conditions, and at the same time increase the monitoring of the disease, so as to achieve early diagnosis and prevention of the disease.
Prevent stress. The control of African swine flu is crucial, especially in winter. Here are a few things to look out for:
1) Cleanliness in the house: Cleanliness in the house is very important. Potassium bisulfate is currently the most commonly used fungicide for African swine fever. The use of potassium persulfate (fecotab) for the sterilization of pig houses can reduce the chance of infection in the pig herd.
In African swine fever prevention and control, disinfection of pig farms is a very critical step. It is a new and highly effective disinfectant. The use of small doses of feed: potassium persulfate (potassium persulfate) can effectively kill the bacteria in the pig farm, reduce the survival rate of the virus in the pig farm, and then reduce the risk of disease. In order to ensure the best bactericidal effect, it is necessary to master the dosage and mode of medication.
2) Strengthen the management of the pig environment: sterilization is only one of the means to eliminate bacteria, and the most basic measure is to ensure the cleanliness and hygiene of the pig production environment. The pigsty should be cleaned frequently, and the feces, feces, feces, and leftover food should be removed in a timely manner, and the sanitation work should be done frequently to ensure the air circulation in the pens and avoid the breeding of bacteria.
Therefore, strengthening the prevention and control of African swine disease, in addition to strengthening the disinfection of pig production, strengthening the cleaning of the pig farm environment is also a very meaningful work. A clean, clean house not only reduces the growth of bacteria, but also improves the comfort and health of the herd. Remove manure, manure and food residues from the barn in a timely manner, and keep the barn dry and ventilated. In the process of pig raising, it is necessary to pay attention to the layout of equipment and equipment to reduce the probability of virus accumulation and avoid cross-infection.
3) Pharmaceutical control: Pharmaceutical prevention and control is an important measure for the prevention and control of African swine disease. The use of "Blue Circle Feitaibao", "Timicosin", "Doxycycline", "Telmicosin", "Doxycycline" and so on as feed additives can effectively eliminate various viruses carried in the body and enhance the body's immunity.
In the prevention and control of African swine fever, pharmaceutical prevention and control is also a very meaningful work. Small animal farming: Blue Circle Fiterol is a highly effective African swine fever vaccine that effectively eliminates swine avian influenza in pig herds, thereby reducing the prevalence of the disease. Telmicosin belongs to a class of broad-spectrum antibiotics with strong antiviral effects. As a new type of antibacterial and anti-inflammatory drug, doxycycline hydrochloride has a good effect on secondary infections caused by bacteria. Adding it to the herd can significantly enhance the herd's immunity and reduce the chance of infection.
Concluding chapter: The outbreak of African swine flu is a big deal for pig farmers. It is of great significance to grasp the occurrence period and population characteristics of African swine fever for effective prevention and control of pig farmers. In view of the various periods of the epidemic, pig farmers can prevent and control the pig farm by disinfecting the pig farm, maintaining the environmental hygiene of the pig farm, and using preventive drugs. Only by taking scientific and reasonable prevention and control measures can we effectively reduce the occurrence of African swine fever and ensure the development and economic benefits of China's pig industry. We should pay close attention to the prevention and control of African swine fever and strengthen our own knowledge and technology of disease prevention to ensure the safety and stability of pig production.
The prevention and control of African swine fever has always been of great significance, and African pigs are in the high incidence season in winter. Farmers should do a good job in epidemic prevention, do a good job in the environmental sanitation and rational use of drugs in pig houses. Only in this way can we effectively control the occurrence of African swine fever, ensure the health of pigs, and improve the efficiency of pig breeding.
