What are the causes of sow constipation, how to prevent sow constipation? I believe this problem about sow constipation is one of the most important questions for farmers' friends. Let's learn about the causes and prevention measures of sow constipation. 1 Reasons for sow constipation 1.1 Physiological incentives Sows to the late pregnancy (85d to delivery), with the increase of the age of pregnancy, the growth of the fetus is accelerated, the fetus in the body to form a compression of the rectum, resulting in slow rectal peristalsis, it is easy to form constipation. This is especially true in sows with large litters and large newborns. In addition, from the 30th pregnancy to the end of breastfeeding, in most farms, the sows are spent in the single-limit bar and the delivery column, lack of exercise, resulting in reduced intestinal function and dry stool. Cause constipation. 1.2 Insufficient drinking water Most large-scale farms use drinking fountains to automatically drink water, but there are still water pipes, water cuts, and insufficient water flow. Because the sows need more water, these conditions can cause the sows to run out of water, sows' drinking fountains. The flow rate should be no less than 1.5 L/min. The free-range households are more likely to suffer from insufficient drinking water due to the management factors of the farmers. Long-term drinking water will cause the stool to dry, which will cause constipation. Insufficient drinking water can also cause too low feed intake of sows, which seriously affects the sow's own needs and the formation of milk, which has a very negative impact on piglets. 1.3 Stress factors Due to the high temperature of the pig house in summer, the evaporation is large, the body temperature of the sow is correspondingly increased, and the pig body needs a large amount of perspiration and heat dissipation, which will cause serious loss of water in the sow body, resulting in constipation. Sudden replacement of feed, sudden changes in the environment, and changes in the feeding system can cause endocrine disorders and cause constipation. 1.4 Nutritional ingredients are too fine Higher energy and protein content, relatively low crude fiber content, will cause sow intestinal aggregation, can not be discharged as soon as possible. Or the crude fiber content is too high, dry is not easy to digest, and it is easy to cause constipation. 1.5 Sow material ratio is unreasonable Strictly limited feeding, the ratio of sow material is unreasonable, the volume of feed per unit mass is small, and a small amount of feces in the large intestine is retained for a long time and cannot be discharged in time. The moisture in the feces is excessively absorbed in the large intestine, forming constipation. 1.6 Insufficient nutrients in the feed The salt in the feed is too low, the mineral element content is unreasonable, and the B vitamin deficiency is caused, resulting in insufficient drinking water or slow bowel movement caused by constipation. 1.7 The occurrence of infectious diseases, especially the occurrence of heat sickness in summer is the high season of swine disease. The occurrence of many heat diseases can easily cause the physiological function of sows to weaken and the body temperature to rise, such as blue ear disease and swine fever. This causes constipation in sows. 1.8 Mycotoxin poisoning Mildew of feed, especially aflatoxin poisoning, causes constipation or diarrhea in sows. 1.9 Abuse of antibiotics Antibiotics also affect the beneficial bacteria in the intestines while inhibiting harmful bacteria, causing serious imbalance of intestinal flora, leading to drug-induced constipation. 2 symptoms of sow constipation Poor spirits, loss of appetite, difficulty in defecation, often tailing to make a state of defecation, no feces discharge, or excreted feces dry, spherical, thirsty hi drink water, conjunctival flushing. The urine is yellow and the amount is small. The pregnant sows have symptoms such as not eating, dystocia, stillbirth, and no postpartum milk. 3 Prevention and treatment measures for sow constipation 3.1 Strengthen management Reduce the stocking density and let the pigs return to the natural life mode. The qualified pig farm can carry out large-circle breeding for pregnant sows, rationally group, moderately increase the amount of exercise, promote blood circulation, and reduce the incidence of constipation. 3.2 Feed Nutrition Balance The needs of energy, protein, minerals, vitamins, water and cellulose should be balanced in different physiological stages of sows. The raw materials that are easier to digest and absorb should be used to prepare feeds with balanced nutrient levels and reduce feed. The probability of staying in the digestive tract. The use of high-quality feed, using the latest amino acid balance technology, can fully reduce the protein content of the diet under the premise of ensuring the nutritional needs of the sow, to achieve the purpose of reducing excrement. Conditional farms can increase the content of cellulose by increasing the amount of silage, and reduce the incidence of constipation in sows. 3.3 Do a good job in immunization to reduce the incidence of infectious diseases The prevention and treatment of some viral diseases is very difficult. Once the disease occurs, it will have certain impact on the sow. The effective way to prevent and cure is to strengthen the immunization, strengthen the feeding management, and use the immune function regulator to enhance the resistance of the pig and improve The vaccine effect reduces the incidence of febrile diseases and effectively controls the severity of febrile diseases. In the hot and hot season, it is especially necessary to do vaccine vaccination for diseases such as swine fever, highly pathogenic blue ear disease, Haemophilus, pig erysipelas and pneumonia, and strengthen ventilation and keep the pens dry. 3.4 Supplying sows with clean and sufficient drinking water Especially in the hot summer, to ensure the supply of quality drinking water, the flow rate of the drinker should be 1.5 ~ 2.5 L / min. Adding vitamins to drinking water when the herd is stressed can increase anti-stress resistance. 3.5 Put the quality of raw materials off Eliminate the influx of ultra-high moisture and mildew materials, and add a mildew remover to the feed. In the rainy season, the feed should be strictly controlled, and the feed should be used as needed. It should not be placed for too long. 3.6 Use of biological agents For sows that have developed constipation, biological agents such as microecology can be added to the feed. The microecological preparation contains a large number of live bacteria, which can promote the digestion of the feed and the peristalsis of the intestine, and contribute to the relief of constipation. Pregnant sows can add 10% to 20% bran to the feed 30 days before the birth, and the bran has a slight diarrhea effect, which can effectively reduce the occurrence of constipation in the sow. 3.7 Drug treatment The treatment principle of constipation occurs mainly by rehydration, detoxification, and adjustment of acid-base balance. Intravenous or intraperitoneal injection of 10% glucose physiological saline 300-500 mL, vitamin C 10 mL, twice a day for four or five days. In addition, sodium sulfate 250 g is administered twice a day; liquid paraffin or edible oil is 200-400 mL, once a day. Severe cases can also be washed with soapy water.

Disposable Suction And Irrigation Sets
A Disposable Suction Irrigator Kit is a medical device used during surgery to remove blood, debris, and other fluids from the surgical site. The kit usually includes a straw and rinse tube, both of which are disposable and designed to be used only once. Suction tubing is used to remove fluid from the surgical site, while irrigation tubing is used to introduce sterile saline or other solutions to the surgical site to help clean and irrigate the area. The single-use nature of the kit helps reduce the risk of infection and cross-contamination between patients.
