Three major prevention and control misunderstandings and treatment methods for pig foot-and-mouth disease
Pig foot-and-mouth disease This pig disease is not too small, it is the "head" of all pig diseases, it can be spread, if the pig group is not resistant to the disease, a virus will develop. However, there are many pig farms that have a misunderstanding of it. The following small series will introduce you to the prevention and control of pig foot and mouth disease and treatment methods! The main symptoms of foot and mouth disease in pigs: 1, characterized by hoof blisters and erosion, body temperature increased by 40 ~ 41 ° C, systemic symptoms are obvious, hoof crown, hoof fork, hoof and other places appear red, swollen, hot pain, the formation of blisters and ulceration. 2, severe infection, hoof shell may fall off, limp, lying down. 3, sick pig's nose, mouth, gums, tongue, breasts (mainly lactating sows), visible blisters and spots. 4, piglets often die from myocarditis, hemorrhagic enteritis. 5. Bacterial diseases such as secondary secondary streptococci and Haemophilus parasuis cause a large number of deaths. After understanding the symptoms of foot-and-mouth disease, many farmers reported that the more treatment losses were found during the prevention and treatment of foot-and-mouth disease, in fact, it may be possible to enter the misunderstanding when controlling the foot-and-mouth disease of pigs. Three major mistakes in preventing and controlling pig foot-and-mouth disease: 1, random injections The habit of raising pigs to "inject a shot when they see a disease" is not too much for pigs infected with foot-and-mouth disease, except for stress and speed of transmission (multiple pigs share a needle and operators as a medium of communication). More help. If some anti-allergic compound preparations such as central nervous system antipyretics, aminopropanoid, and dexamethasone are injected, it will undoubtedly cause a sharp decline in cellular immune function in animals. 2, messy disinfection Foot and mouth disease is a respiratory viral disease. The foot-and-mouth disease virus first destroys the respiratory mucosal defense barrier. The chemical disinfectant is disinfected with pigs. Because it is not selective for sterilization, it will seriously damage the respiratory mucosa of the pigs, making the respiratory mucosal barriers riddled with holes and viruses. Open the door to convenience. Frequent disinfection with pigs in pig houses will not only cause excessive moisture in the air, but also seriously damage the micro-ecological environment in the pig house, which will only delay the recovery time of the pigs. 3, beat the vaccine Vaccines are used to prevent disease and are not used to treat diseases. When the pig is in the onset of the disease, vaccinating the pig is tantamount to worsening the pig's death. Pig foot and mouth disease prevention and control program 1. Because the disease may occur all year round, it is recommended that the whole sow be vaccinated with foot-and-mouth disease in April, August and December each year. The foot-and-mouth disease vaccine is given to each of the pigs at 70 days of age and 100 days of age. 2. Threatened farms (with disease sites around) A, vaccination Emergency vaccination: O-type + A-type emergency immunization can be used. Pigs and adult pigs were inoculated with 2 servings, and nursery pigs were inoculated with 1 serving. B. Disinfection: The frequency of the disease field should not be too high. It should be disinfected once every 7 to 10 days, and disinfected once a month. To enhance disinfection, the pigs can be disinfected with 0.5% peracetic acid, once every 7 days; disinfected in the pig pens with 2% glutaraldehyde, once every 7 days; at the foot of the porcine pig house with 3% caustic soda Disinfection, 0.5% Xinjie Quenching Liquid for hand disinfection. C, drug health care Fengqiang Blue Qing 1000g + Hengjikang (amoxicillin + clavulanate potassium) 500g mix of one ton, high-quality multi-dimensional 500g water one ton, for 7 days, this program can effectively improve the immunity of the herd Reduce the chance of pigs infected with foot and mouth disease. Control of the affected farm: 1. Vaccination (testing pigs before injection, sick, thin or not giving birth to sows) Pigs without clinical symptoms, immediately intramuscular injection of foot-and-mouth disease O-type + A-type inactivated vaccine, according to pig size The first 2-4 ml can be combined with the intramuscular transfer factor of 0.5 to 1 ml per head. 2, disinfection: the frequency of the disease field should not be too high, 7 times a small disinfection, 1 month, 1 large disinfection can be. Block the farm. The sterilized medicinal acid preparation and the iodine preparation are used alternately at a concentration of 300:1. The pig pens were disinfected with sodium hydroxide (2% caustic soda) for 3 days. The door of the porch pig house is disinfected with 3% caustic soda water, 0.5% Xinjie sputum liquid is disinfected by hand; all channel walls can be sprayed with 20% lime milk. 3, drug treatment Fengqiang blue green (1000 kg material plus 1000 g), used for 10 days; high-quality multi-dimensional drinking water, used for 10 days. Hengjikang (500 g / ton of material), used for 5-7 days. Intramuscular injection of amoxicillin (1 bottle / 50 kg body weight) + Qingkailing (0.2 ml / kg body weight), can be eaten as soon as possible. At the same time, adding 0.4% citric acid to the feed, adding high-quality probiotics at the stage, this program enhances the non-specific immunity of the whole pig population; effectively controls the secondary infection of bacterial diseases such as streptococcus, thereby effectively reducing the mortality. 4, sick pig treatment Keep dry, rub the iodine glycerin in the mouth of the pig's mouth; sprinkle with amoxicillin powder on the rot of the hoof, 2 times a day. In severe cases, mix thoroughly with herb cream (pot ash), borneol and vegetable oil (preferably sesame oil) once a day. Too serious and timely elimination, do pollution-free treatment. 5, post-healing repair After a serious illness, major illness, physical decline, and to be restored, it is recommended to supplement the beneficial bacteria with high-quality probiotics to enhance the resistance for 4 days. Pig farmers should pay attention to the fact that in the autumn of October each year, many pig farms began to carry out autumn defense intensively to carry out winter and spring disease prevention. In recent years, the simultaneous occurrence of foot-and-mouth disease and viral diarrhea has caused huge losses to the farms, and individual farms have even devastated. When the pigs are suspected of foot-and-mouth disease, try to reduce the stress. Try to use water or mixed wet materials to prevent the sows from cracking the hooves. Do not catch pigs or pigs, keep them dry and reduce the rushing.
