After more than a year, the outbreak of African swine fever has passed, and there are cases of resumption and distribution in the country.
Although there is no vaccine and no effective prevention and control methods, the pork gap and the increase in pig prices have driven the enthusiasm of the national pig farms to resume production.
Xiaobian recently found in the work that some areas are circulating the news of the second outbreak of African swine fever. Some pigs have started to develop fever, fever, anorexia, cyanosis, rebound after injection, and individual deaths accompanied by respiratory tract. symptom. There are also cases of sow abortion and premature birth, accompanied by the return of the sow herd and the performance of not estrus. Xiao Bian also visited some pig farms and found that it was not African pigs. What disease is it?
First, the flu is accompanied by respiratory tract caused by secondary infection
Many pig farms call, the same description is that recently there are a few rounds of fat pigs on the farm, fever, anorexia, body temperature above 40 degrees, feed intake decreased, body redness, spread fast, three or four days, 50% fat Pigs have symptoms, injections can reduce fever, but the effect of fever is poor, individual pigs die, after 5 days, late pigs have respiratory symptoms, severe cough, some nose, nosebleeds and so on.
As soon as I saw this description, I was unlikely to respond to African swine fever, because the spread of African swine fever is very slow, and it may take more than 10 days for adjacent pens to spread, unless it is considered to be a string.
Like this speed of transmission, in this season, the incidence of influenza, uncontrolled, secondary respiratory infection caused by the respiratory tract is the main reason.
However, the farmers have also reacted to the previous flu. They have not experienced dead pigs. It is better to use electric sapphire granules + amoxicillin. How can I not control this time, and there is an emergency around it. . In fact, the flu is a virus, and the flu multi-host exists, which leads to an increase in the probability of variability. Every year, the situation is different and may be stronger.
This year’s epidemic of the flu has just begun, the main performance is the use of conventional drug mixture to prevent poor results, must be used within 3 days of the onset, large doses of antipyretic detoxification Chinese medicine such as Banlangen + silver yellow + sensitive antibiotics, 3-4 times Drink water. Moreover, antibiotics try to select antibiotics that are not commonly used on pig farms, so that bacterial resistance can be solved, and attention should be paid to adding multi-dimensional and antipyretic drugs.
Second, the autumn sow detoxification period, blue ear, pseudo rabies fluctuations, caused by miscarriage, premature delivery
The sow abortion and premature birth in some pig farms are also considered to be the case of African swine fever. Everyone may be frightened by African swine fever, and once it shows typical performance, it will be considered as African swine fever.
It is normal for the sows to fluctuate in the fall. Generally, the sows have experienced a tumultuous weather. The body has accumulated too much moist heat toxins, enters the fall, the weather is cool, the sows have a detoxification period, and the temperature difference in the autumn and evening becomes larger. Close the door and close the window, the ventilation is not good, sows are prone to sub-health conditions such as eyelids, tears, constipation, and yellow urine.
At the same time, from August to November each year, the blue ear and the pseudo rabies are unstable periods. Sow detoxification caused weak babies, increased stillbirths, and blue ear rabies fluctuations caused by premature birth, fetal movement or abortion.
After the summer of September, it is necessary to strengthen the detoxification health care and blue ear health care of the sow. It is recommended to add the Chinese medicine detoxification + tilmicosin program.
In short, in the context of such a high market, the farm should indeed strengthen the management and detailed operation. All abnormal performances on the farm should be dealt with in the first time. Once the delay is made, some clinical symptoms will appear.
At the same time, don’t be scared every day, fearing that African pigs will enter the farm. At this time, we must have a concept of biosafety, strengthen staff execution, appropriately enhance the health care of pigs, improve the immunity of the herd, and wait for vaccine development. In addition, we have no choice but to succeed.
