Common causes and treatments for swine fever
Some farmers suddenly found that their pigs could not stand up during the breeding process, but did not know what caused them. In fact, many diseases in the daily breeding process will make the pigs unable to stand. So what are the common diseases that cause swine fever? How should farmers control it?
1, sow postpartum 瘫痪
If the sows look down on breastfeeding just after they are produced, it is likely to be replaced by postpartum. In general, sow diets contain less calcium, phosphorus, or improper proportions of the two are the main causes of postpartum paralysis in sows. Treatment: If the sick sow is mainly in the hind limbs, the symptoms are lighter. You can add a certain amount of good quality bone powder and calcium tablets to the feed in time, and insist on driving for 1 to 2 hours every day to promote the sow. The body's absorption of calcium and phosphorus. If the symptoms of the sick sow are heavier, you can inject 100mL ~ 150mL 10% glucose injection, 40mL ~ 60mL 10% calcium chloride injection, pay attention to ensure that calcium chloride is injected into the vein, not allowed to leak to the skin, once a day for continuous use 3 to 5 days. Alternatively, a 5% dextrose injection supplemented with an appropriate amount of vitamin C and 10 mL of 20% sodium soda may be administered intravenously.
2, piglet legs
In the production, the piglets are born after the birth of the hind legs, which are dog-like and difficult to walk; a few of them show that the front and rear limbs are unable to stand. It is generally considered to be a mycotoxin accumulation in sows or a deficiency in selenium, methionine, vitamin E and choline in pregnant sow feed. Treatment: Firstly, the colostrum intake can be ensured by manual care. If the milk is difficult, the artificial milk can be fed 20mL. After taking the colostrum, the two hind legs should be taped to the normal leg distance and then used. One end of the string fastens the piglet's tail, and the other end is tied with a live knot on the steel tube of the bed. The purpose is to force the piglet's hind legs to stand and prevent it from sitting down. This prevents the danger of being killed by the sow. When the sow is feeding, the knot will be opened in time to care for the milk, which is usually about 2 days. For the front and rear limbs are eight-legged legs and weak small eight-legged piglets without treatment value should be eliminated early.
3. Streptococcal disease
Streptococcal disease is generally prone to occur during the hot and humid season from July to October. Among them, arthritic streptococcal disease shows swelling of the limbs or limbs, pain, lameness and even standing. Treatment: intramuscular injection of penicillin 40,000 units / kg, 2 to 3 times a day for 3 to 5 days; or intramuscular injection of ceftiofur sodium 10 ~ 20mg / kg, once a day for 3 days; or with large The combined intramuscular injection of penicillin and streptomycin was used for 3 to 5 days. It can also be treated with traditional Chinese medicine: dandelion 25g, purple diced 20g, honeysuckle 20g. Usage: Water decoction to slag mix feeding, 2 times a day for 2 to 3 days.
4. Haemophilus parasuis
Haemophilus parasuis can also cause porcine joint disease that can't stand. Mainly characterized by elevated body temperature, joint swelling, lameness, weight loss, rough hair, cough, difficulty breathing, redness or pale skin, anorexia, lethargy, and diarrhea. The difference between Haemophilus parasuis and streptococcal disease is that the Haemophilus parasuis usually has edema of the whole limb or partial swelling of the joint, and is accompanied by symptoms such as respiratory tract and eyelid edema. Treatment: The whole group was treated with sulfamonomethoxazole (first dose of 80 mg/kg body weight, maintenance amount 50 mg/kg body weight) and an equal amount of sodium bicarbonate mixture was added twice a day for 5 days. Simultaneously, the clinical symptoms of the diseased pigs were intramuscularly injected with oxacillin sodium 0.015g/kg body weight, twice a day, according to the size of the individual pigs, and given Bupleurum injection 10~20mL/head daily, divided into 2 intramuscular injections. Used for 5 days.
Observing whether there is a standing problem in pigs can be observed by means of timed quantitative feeding. If the pigs have not yet stood up to the trough for feeding during the feeding time, they may be paralyzed, so the farmers should be discharged when they are found and treated early.
