Diagnosis of postpartum uterine diseases in sows by using B-ultrasound in pigs

In case of postpartum uterine prolapse or incomplete uterine prolapse, 0.1% potassium permanganate solution or 500-1000mL of saline solution can be injected into the uterine cavity to restore the uterus with the help of the pressure of the liquid, and the recovery state can be observed by using B-ultrasound in pigs. For complete uterine prolapse. First, remove the feces attached to the mucosa and wash with 0.1% potassium permanganate solution or 1% saline solution. For severe edema, wash with 3% alum water. During the restoration, two people hold the uterus and vagina at the same height, one person holds the uterine horn with the left hand, and the right thumb restores from the end of the uterine horn; then hold the hand into a cone like turning the intestines, and push hard when the pig is not straining, and turn it inward in turn. Use this method to push the two uterine horns into the uterine body one after another, and at the same time push the uterine body into the pelvic cavity and abdominal cavity. After the restoration is completed, the vulva is sutured with two stitches of thick silk thread to prevent further prolapse, and the recovery state should be observed frequently by using B-ultrasound in pigs. If necessary, anesthesia is given, and antibacterial drugs are injected to reduce inflammation after restoration. When the uterus is completely prolapsed, it can only be removed.

If the sow is lame after delivery and has trauma, antibacterial and anti-inflammatory drugs are needed: use 10 mL of Antongding, 3.2 million U of penicillin, 1-10 mL of vitamin B, 2 times/d, intramuscular injection; dexamethasone 10 mL, 1 time/d: intravenous injection of 10% calcium gluconate 150-200 mL, 1 time/d, for 6-10 days. For severe pain, add 20% sodium salicylate 20 mL during intravenous injection, and procaine can be used to block the lumbar pain.

For postpartum paralysis of sows, dry and crush pig bones or other fresh livestock and poultry bones, mix them with feed, and artificially force them into the mouth of the sow until each sow is full every day. For severe cases, use 5-10% calcium chloride injection 40-80 mL once intravenously. You can also apply high-proof liquor to the skin and perform manual massage. To promote blood circulation and restore nerve function. In addition, the content of wheat bran and rice bran in the diet can be appropriately increased.

B-ultrasound for pigs plays a certain role in preventing and controlling sow abortion

The prevention and control of sow abortion should first take comprehensive prevention and control measures such as strengthening immunity and disinfection, strictly abide by various rules and regulations, and adhere to white breeding and self-feeding. If necessary, drug prevention and treatment can be taken. For the prevention of infectious diseases that cause sow abortion, a reasonable epidemic prevention procedure should be formulated according to the occurrence and prevalence of the disease in the region and the farm. When a certain infectious disease occurs in the farm, drug treatment should be taken in time. Frequently use B-ultrasound for pigs to check the condition of the fetus.

After the sow gives birth, drink "Yimu Brown Sugar Soup" immediately, and give it to the sow that has just given birth. Because this prescription can promote uterine contraction, restore the uterus as soon as possible and discharge the remaining blood stasis (lochia) in the uterus, and it also has a bactericidal effect, it can prevent uterine infection. After use, observe the repair of the uterus with B-ultrasound for pigs. For the prevention and treatment of nutritional abortion, we should insist on using full-price balanced compound feed, control the amount of feed at each stage of sow development and pregnancy, and use pig B-ultrasound to observe the condition of the fetus. Rationally use vitamins such as vitamin E and trace elements such as calcium and phosphorus; strictly implement the feed safety system, and control the purchase, transportation, storage and feeding of feed. Resolutely put an end to the use of moldy and toxic feed to feed sows.

Large-scale pig farms should have a reasonable layout, complete facilities, and fully enclosed pig houses to create a good environment for the growth and development of sows, and rationally select and match to prevent stealing, random matching and inbreeding. Minimize the stress caused to sows by weather changes and human factors. After abortion of sows, in addition to reasonable drug treatment and balanced nutrition according to the disease that caused the abortion of sows, reasonable restorative treatment should be carried out on the reproductive organs of aborted sows, and breeding should be carried out after the sows recover and naturally estrus. The use of aphrodisiac drugs should follow the principle of less or no use. Sows should be regularly immunized and dewormed.
