The incidence of African swine fever is regular! Do pig farmers understand? If you don't understand, check it out
As we all know, African swine fever has always been a problem for pig farmers, but no farm has completely eliminated the emergence of African swine fever epidemic. Therefore, it is necessary to grasp the pathogenic mechanism of African swine fever in order to minimize the loss as soon as possible. Have a deeper understanding of the pathogenesis of African swine fever.
The law of pathogenesis. 1.Period: Data show that the epidemic season of African swine fever is early spring, late autumn and winter. During this period, farmers must pay close attention to the development of the disease and take preventive measures accordingly.
ASF occurs in early spring, late autumn and winter, when weather conditions favour the spread of the disease. In spring, the temperature increases, the body's metabolic ability decreases, the body's resistance decreases, and it is susceptible to the invasion of various viruses; Autumn is a cold and dry season, and the stored food is prone to produce germs and cause respiratory diseases in pigs; In winter, low temperature, high humidity and poor air circulation conditions can easily cause digestive tract diseases in pigs. Therefore, during the spring and autumn seasons, it is necessary to do a good job in the monitoring and prevention and control of epidemic diseases, and protect pigs in a timely manner.
2.The African swine disease epidemic has a certain regularity. Generally speaking, older sows are the first to get sick, and during lactation, they are less likely to get sick. In addition, there are some differences in the disease status between different breeds, among which the first trimester is the most common, followed by empty pregnancy, the third trimester is low, and the lactation period is low.
African swine fever is a typical infectious disease, and its incidence is positively correlated with the time of onset. Generally speaking, older pigs are the first to be infected by African CSFV due to their weakened immune function and poor immune ability. As a gilt, because it is in the stage of growth and development, its immunity is relatively strong, so its resistance to the virus is stronger than that of elderly pigs; Cows are less likely to get sick than other age groups due to protection from breast milk and vaccines.
In addition, the incidence of sows varies from gestation to gestation. In the early stages of pregnancy, due to the low immune function of the body during pregnancy, the resistance is reduced, and it is very easy to be infected by viruses; However, due to the absence of pregnancy hormones, the immune function of empty sows was gradually improved, and the probability of disease was reduced. In the third trimester of pregnancy, due to the gradual improvement of the body's immunity, the fetus matures, and the body's resistance is relatively strong; The immune function of lactating piglets has basically been restored, and their susceptibility to viral diseases has been significantly reduced, and the probability of disease has been greatly reduced.
The prevention and control of African swine fever should be targeted at different stages and different physical conditions of pigs, and preventive measures should be formulated in a targeted manner, and at the same time, it is necessary to increase the monitoring of the disease to achieve early diagnosis and development of the disease.
The focus is on prevention.
The prevention and control of African swine fever, especially in winter, is a very critical issue. Here are a few things to look out for:
1.Disinfection of the barn: It is important to have a thorough disinfection of the barn. One of the most commonly used fungicides against African swine disease is persulfate. The use of "small animal pasture": Disinfection and sterilization of pig farms with non-CTA (potassium bisulfate) can greatly reduce the chance of virus transmission.
In African swine fever prevention and control, disinfection of pig farms is a very critical step. Potassium bisulfate is a very effective antibacterial drug, which has a great effect on the disinfection of the human body. The use of livestock and poultry herding: non-gram Taibao (potassium persulfate) to carry out comprehensive sterilization of pig farms, can effectively kill the germs in the pig farm, but also can reduce the viability of the virus in the pig herd, thereby reducing the probability of disease outbreaks. In the process of medication, it is necessary to grasp the dosage and usage of the drug to ensure the effective bactericidal effect of the drug.
2.Do a good job of cleaning the pig house: Sterilization is only one way to kill bacteria, and the most basic measure is to ensure the cleanliness and cleanliness of the pig house. It is necessary to do a good job in the sanitation of the pigsty frequently, clean up the manure, manure, feed and other sundries in time to ensure air circulation in the pigsty and prevent the breeding of bacteria.
In the prevention and control of African swine disease, in addition to doing a good job of disinfection, the cleaning of the pig house environment is also a major part of the prevention and control of the disease. A clean and hygienic environment in the pig house can not only reduce the growth of bacteria, but also improve the comfort and health of the animals. Regularly remove dirt in the pigsty, such as manure, garbage, feed, and ensure that the pigsty is clean and has good air circulation. In the process of pig raising, it is necessary to pay attention to the reasonable arrangement of equipment and equipment to reduce the probability of accumulation of viruses and avoid mutual infection.
3.Drug control: Medicine** is an indispensable measure for the prevention and control of African swine disease. Add some drugs to the feed, such as: Lanyuan non-Taibao, tilmicosin, doxycycline hydrochloride, etc.
Drug control is a comprehensive prevention and control strategy for the prevention and treatment of African swine fever. Animal Xiaomai: This product is a highly effective African swine avian influenza vaccine, which can reduce the outbreak rate of pig herds and is a highly effective new anti-influenza A drug. Telmicosin belongs to a class of broad-spectrum antibiotics with strong antiviral effects. Doxycycline hydrochloride is an antibacterial, anti-inflammatory, antibacterial, and antibiotic that prevents secondary infection. Adding the above preparations to the diet of piglets can significantly enhance the body's immunity and reduce the occurrence of diseases.
Abstract:Studying the pathogenesis of African swine fever is the key to ensure the safety and effective prevention and control of pig production. Understanding the occurrence period and population characteristics of African swine disease will help guide farmers to do a good job in prevention and control. For all periods of disease occurrence, the farm can be disinfected, the farm hygiene can be maintained, and the drug prevention and control can be carried out. Only by taking scientific and reasonable prevention and control measures can we effectively reduce the occurrence of African swine fever, ensure the health of pigs, and improve the economic benefits of animal husbandry. At the same time, we should also pay close attention to the research and prevention of African swine fever to improve our knowledge and ability of disease prevention and ensure the smooth progress of pig production.
In China, the prevention and control of African swine fever is very crucial, and winter in China is the high season of non-plague. Farmers should do a good job of disinfection, ensure that the pig house environment is clean, and take corresponding prevention and control measures in a timely manner. Only in this way can we effectively reduce the occurrence of African swine fever, ensure the health of pigs, and improve breeding efficiency.
