In the cattle industry, calling people to "talk about the epidemic" is foot-and-mouth disease. The impact is no less than that of African swine fever. Once discovered, it can be said to be a disaster. It's really hard to have an egg in the nest, and there may be nothing.
Regarding the harm of foot-and-mouth disease, you must not talk about it lightly. If you think so, it means that you have not suffered. Anyone who has experience will not take it lightly. The reason for saying this is that the only purpose is that we can carry it through by observing diligently and doing a good job in epidemic prevention. Next, I will say that foot-and-mouth disease is commonly known as "mouth sore" and "foot-and-mouth disease". It has three characteristics: acute, febrile, and contact infection. It is classified as a type of infectious disease by my country. You say you are afraid of it. How to know it? The clinical manifestations are: blisters and ulcers on the oral mucosa, lips, hoof and breast skin. So many friends ask, where is this virus hidden? I said that it is mainly in the blisters, saliva, blood, feces, urine and milk of sick cows. At the same time, this virus is very resistant to the outside world, and is sensitive to sunlight, temperature, acidity, and alkalinity. This shows the usual process of raising cattle. Pay attention to the sun in the middle. Infected sick cattle are the source of infection. Once they are found to be abnormal, they must be isolated in a small house, and the cattle troughs and water tanks that have been eaten are isolated because they are infected through damaged mucous membranes, skin and respiratory tracts. Some experts say that there is a certain periodicity that it will be popular every 1-2 years or 3-5 years. As a farmer, it is better to do your homework in this area in advance and know what to do so that you will not be confused. Combining theoretical knowledge, I analyzed the symptoms of foot-and-mouth disease in detail: 1. The average incubation period is 2-4 days, and the elderly can reach about 1 week. 2. A thermometer can be inserted into the anus of the cow to measure the body temperature of the sick cow. If it rises to 40~41C, it is accompanied by lack of energy, loss of appetite, and drooling. 3. If after 1-2 days, white blisters of 1 to 3 cm square appear on the inner surface of the lips, gums, tongue and cheeks of the sick cow, drooling a lot, the blisters rupture and form erosions, and the cow eats little or no food. 4. At the same time or after the appearance of the blisters, blisters also appeared on the toes of the hoof and the skin of the crown of the hoof, and the cows were reluctant to walk. 5. Sometimes blisters appear on the nose and nipples of cattle, forming a rough, hemorrhagic granular erosion surface. So what I’m talking about here is benign foot-and-mouth disease. It usually takes about seven or eight days to heal itself. When suffering from this kind of oral disease, you can wash it with salt water or 0.1% potassium permanganate solution, and then apply it. With 1% to 2% sub-alum or iodine glycerin, you can also sprinkle some traditional Chinese medicine ice boron on the oral cavity, and apply penicillin ointment. If it is a malignant foot-and-mouth disease, in addition to the methods mentioned above, cardiotonic agents and tonics (such as dextrose saline, etc.) can be used. The treatment can be intramuscular injection of mixed feeling Tianzun or Foot-and-mouth Jinzun, according to the cow's weight of 200 kg, for 3-4 days. At the same time, the mixture was fed with Astragalus Shuangkang + Qingwen Baidukang for one week. Prevention: During the high-incidence period, use Astragalus Shuangkang + Qingwen Baidukang in combination with feeding, and use it for one week every month. The pens should be sanitized and disinfected. In short, it is necessary to observe the cattle frequently when they are eating. If symptoms such as erosions and blisters are found, they must be isolated and reported if necessary. There must not be a fluke. At present, I do not have effective defensive measures on my side. I can only control it from the aspects of hygiene and the source of sick cattle.
