Why did the pig procrastinate?

Refer to comprehensive data: 1. We often say "proctoptosis" is the rectal prolapse of pigs, which is caused by the pressure on the rectum and the anus turning out. Rectal prolapse can occur in pigs of any age and season, especially in commercial pigs weighing 5-5-100 kg, mostly in winter. Small rectal prolapse will affect the growth and development, which may lead to the death of pigs. Symptoms: From the appearance symptoms, it is mainly that the end of the pig's large intestine and the inside of the anus protrude out of the anus, and there will be no abnormal phenomena in light cases, and edema, ulceration and bleeding will occur in severe cases. Porcine proctoptosis can be divided into two situations: the first is that the sick pig can recover itself when standing, but it can emerge when defecating; The second is that sick pigs can't return to themselves when they stand. Incidence: Pigs of different ages may have rectal prolapse. According to reports, the incidence rate of pigs aged 1.5 ~ 3 months is the highest, and the general incidence rate is about 0.5% ~ 1%. However, when the weather changes from cold to wet, the incidence rate increases, sometimes as high as 10%. 2. Cause of disease: The pig rectum is fixed in a complex reticular structure, and it will not come out due to defecation under normal circumstances. However, due to some diseases or physical factors, when this supporting structure is weakened or excessively compressed, prolapse will occur. When some pigs defecate, some rectal mucosa may temporarily prolapse; Sometimes this happens when pigs cough. It can be speculated that this kind of pig has a great possibility of complete prolapse under some inducing factors. The causes of rectal prolapse are very complicated, and there are generally the following factors: ① Feed factors: degeneration or mildew of some ingredients in feed, sudden change of feed, too little crude fiber (such as insufficient bran and barley) or too much crude feed, and too high calcium content in feed (such as feeding pigs by hens, causing calcium to form stones in urethra and causing obstruction) may all cause rectal prolapse. ② Pathological factors: Severe inflammation caused by some diseases stimulates rectal prolapse. The high incidence of rectal prolapse may be related to swine fever. Constipation caused by some diseases can also be secondary to rectal prolapse. Cough will lead to an increase in abdominal pressure, which will lead to rectal prolapse. However, rectal prolapse is rarely caused by diarrhea. ③ Physical factors: high feeding density, cold piggery, and pigs clustered together. If a pig coughs, it is very easy to get sick. When sows are raised in a positioning fence with a large slope or tied to a slope, they will increase abdominal pressure and cause rectal prolapse during high-density delivery and transportation. ④ Genetic factors: It is certain that rectal prolapse is related to heredity. It was found that the incidence of rectal prolapse in piglets bred with Yorkshire boars was 3.3 times higher than that in ordinary pigs. Inbreeding will show genetic defects and increase the incidence. 3. Control measures: (1) Feeding qualified complete feed. ⑵ Prevent fright, reduce stress, handle with care when changing groups, and keep warm in winter. (3) Preventing inbreeding. (4) The pigs that have appeared should be isolated in time and the purse should be stitched. When sewing, needles, threads, scissors, surgical instruments, arms and parts coming out of anus should be cleaned and disinfected first. If there is edema, squeeze the edema by hand. If it is suppurated, it is necessary to peel off the carrion and clean it, then gently send it to the anus and sew it up. The most important thing is to inject rice and penicillin into the sea point after operation, and the dose should be appropriate. 4. Recommended treatment: Rectal prolapse in pigs is often treated, and most people use the method of suturing anus to prevent rectal migration. The cure rate is low, and it takes a long time, with great side effects, poor defecation of pork chops, loss of appetite and aggravation of illness. In the long-term practice of raising pigs, the author explored a new method to cure proctoptosis in pigs quickly and achieved good results. This paper introduces the operation and drug preparation method: (1) fix the hindquarters of pigs, rinse them with normal saline and apply anti-inflammatory powder. ⑵ Blow out the open flame after the prepared grain is ignited, and smoke the anus and intestinal surface, stimulate local nerves and blood vessels, promote intestinal contraction, recover automatically, and it won't appear again in the future, and the phenomenon of sick pig monster will stop. (3) Preparation method of medicinal roll: 50-100g of Folium Artemisiae Argyi, 25-50g of Rhizoma Acori Graminei and a little borneol powder are alternately mixed, rolled into a tube shape with a thick paper roll, pasted with paste and dried. 5. Wash the affected area with 0. 1% ~ 0.2% warm potassium permanganate solution, dry it with sterile gauze, and then apply a proper amount of snail meat paste to the affected area. The specific method of snail meat paste is: wash the snail, remove the shell and take the meat, wash the snail meat and the tools used to mash the snail meat with 0.2% potassium permanganate solution, and then mash the snail meat into paste. It is realized that snail meat has a strong function of detumescence, convergence and muscle contraction, which can reduce rectal mucosal edema and promote rectal muscle contraction, so the cure rate is high, snail meat is easily available in ponds and markets, with low cost, good curative effect and simple operation method. For a few severe pigs, although surgical treatment can be completely cured, it is difficult and complicated. Therefore, it is suggested that snail ointment should be used early to treat rectal prolapse. This method is simple and low cost, and pig farmers can treat themselves. However, as a health care veterinarian in modern society, I still hope that pig farmers can take various preventive measures and try not to let their pigs have "rectocele". Once it appears, there will definitely be losses. /Article/ShowArticle.asp？ ArticleID=2428
