What are the symptoms of foot-and-mouth disease (FMD No. 5) in pigs? The best treatments are all here!

After the Beginning of Winter, there was a high incidence of various diseases in pig farms, among which pig foot-and-mouth disease has always been the pig epidemic most feared by farmers, which not only suppresses the growth rate of pigs, but also causes casualties and great losses to farms. What are the symptoms of pig foot-and-mouth disease? What are the best treatments?

What is foot-and-mouth disease of pigs?

1. A brief introduction to Porcine foot-and-mouth Disease: pig foot-and-mouth disease, also known as the fifth disease, is an acute, febrile and contagious infectious disease caused by foot-and-mouth disease virus, which mainly affects cloven-hoofed animals. Porcine foot-and-mouth disease is highly contagious, rapid spread, acute onset, infection and high incidence.

2. epidemic time and characteristics of pig foot-and-mouth disease: pig foot-and-mouth disease mostly occurs in late autumn, winter and early spring, especially in winter and spring, but it can occur all year round in large pig farms and concentrated pig breeding areas. animal products, feed, pastures, drinking water and water, transportation and breeding tools can be the source of infection, diseased pigs are the most dangerous source of infection, and air is also an important transmission medium. Pig foot-and-mouth disease often presents a leaping epidemic, which mainly occurs in centralized pig farms, suburban pig farms and along the traffic line.

Symptoms of foot-and-mouth disease in pigs

1. The main symptoms of swine foot-and-mouth disease are blisters and ulcers.

2. The incubation period of foot-and-mouth disease is generally 2-7 days. At the beginning of the disease, the body temperature rises to 40-41 degrees, depressed, often lying down, eating less or not eating.

3. Newborn piglets do not necessarily have blisters, which are mainly characterized by acute gastroenteritis, acute myocarditis or limb paralysis, and the mortality rate can reach more than 80%.

4. Red-hot plaques appeared in the hoof fork, heel and crown of fattening pigs, and blisters of different sizes were soon formed, which were transparent on the outside, filled with light gray or yellowish liquid, and the blisters gradually enlarged and burst to form red erosion spots; the disease was mild and the culture environment was good for about a week to recover, on the contrary, bacteria secondary infection, lameness, hoof shell shedding.

5. Water robes, erosion and scabbing occurred on the nipple and nasal mirror surface of lactating sows.

Third, the best treatment of foot-and-mouth disease in pigs.

When foot-and-mouth disease or suspected foot-and-mouth disease occurs in pig farms, the diseased pigs should be isolated immediately and then treated for the disease.

1. If pig foot-and-mouth disease is found, we should diagnose and treat the disease in time, isolate, block and disinfect the epidemic area, and bury all dead pigs and pollutants deeply.

2. When an epidemic occurs in individual pigs, they should be isolated in time and then disinfected in the whole field, and the uninfected pigs should be vaccinated with the serum of foot-and-mouth disease virus prevalent in this area.

3. Surgical treatment of diseased pigs with ulcerated hooves to speed up wound healing and prevent secondary infection: wash the ulcerated area with 0.5% potassium permanganate, then apply iodoglycerin, or spray the wound with iodine tincture once a day for three days.

4. Try to avoid injections for sick pigs with high fever. Multivitamins can be added to drinking water, in which vitamin C can be used in combination. We must pay attention to the fact that pigs can never cut off water every day.

5. For the sick pigs who do not eat, the diet will increase the pain due to blisters in the mouth. At this time, you can feed the wet mixture to increase the palatability, and you can also add a little salt to the feed. Pigs like salty food, and adding salt can increase their appetite.

6. For diseased pigs with shelled hooves, "crystal sulfonamide powder" should be applied to the wound, and artificial water and food should be given to some affected pigs that can not move.

Note: generally, pigs suffering from foot-and-mouth disease rarely die, and a small number of deaths are caused by the virus invading the heart, causing myocarditis and dying of heart failure, so it is necessary to observe the state of pigs every day and make timely prevention and treatment.

4. How to prevent foot-and-mouth disease in pigs?

In fact, pig foot-and-mouth disease is also very easy to prevent, as long as we master its "dead point", we can prevent and cure the disease.

1. The winter and spring season is the season with high incidence of foot-and-mouth disease. It is necessary to do a good job in pig houses, strengthen feeding and management, change the mat grass laid in pig houses frequently, have a lot of bacteria and viruses in winter, and disinfect pig houses and appliances regularly. Disinfect the pen with caustic soda and quicklime; spray the space of the pig house with potassium permanganate or iodine solution to disinfect the air.

2. Ensure that the environment in the piggery is dry, the room temperature is controlled between 15-22 degrees, and the temperature of piglets in the delivery room is controlled at 25-28 degrees.

3. To do a good job in the prevention and injection of foot-and-mouth disease, breeding pigs should be vaccinated three times a year, once in March, July and December respectively, and 3 doses per pig muscle. Fattening pigs were immunized twice, the first immunity at 23-25 days old and the second immunity at 60 days old.

Conclusion: the above is about the relevant introduction of foot-and-mouth disease, now winter must do a good job of defensive measures, the majority of farmers must carefully observe the various symptoms of pigs, timely diagnosis and treatment of problems, and do a good job in feeding management and disinfection measures.
