Etiology and Prevention of Anorexia Syndrome in Sows

Sow anorexia syndrome incidence is very common, common in prenatal and postnatal, part of the birth, individual breathing difficulties, some lead to sow elimination, and even cause sow death. For the comprehensive incidence of anorexia in sows and its prevention and control measures are generally introduced as follows:

1. sows anorexia, postpartum

1. Incidence characteristics: At present, postpartum non-eating syndrome of sows is one of the common common diseases during lactation, which is more common in summer. Loss of appetite and even extinction are the main symptoms during postpartum and lactation. Vaginitis, metritis and decreased lactation function of sick sows lead to diarrhea of piglets during lactation, decreased immunity of the body, slow growth or stiff pigs, and even progressive emaciation and weakness and death during weaning during weaning. Sow, or estrus delay, or even repeated with infertility, seriously affecting the production performance of sows.

2. Causes of the disease:(1) Mixed infection of old and new diseases leads to complicated sow epidemics, which seriously affects the growth and health of sows, especially gastrointestinal dysfunction, which is one of the main reasons why sows do not eat. (2) The increase of mycotoxins in raw food seriously affects the health of sows, promotes the incidence of blue ear disease and circovirus, thus affecting the appetite of sows and causing another incentive for sows not to eat. (3) due to the changeable climate, especially the heat and dryness, heat stress, gastrointestinal disorders, insufficient water supply, water pollution, improper nursing of sow delivery, postpartum infection of metritis and many other reasons.

3. Prevention and control measures:(1) Strengthen feeding management, strengthen environmental control of farrowing sows, prevent heatstroke and cool down; Strengthen the environmental sanitation of piggery, maintain ventilation in the piggery, avoid startling, stress response and reduce noise. Maintain water sanitation and ensure adequate drinking water. (2) Do a good job of sow immunization, improve the immunity of sows, and strengthen the work of sanitation and disinfection. (3) to ensure the quality of sow feed raw grain, prohibit feeding moldy feed. In summer, you can add mold removal agent (mold removal one) and baking soda powder in the feed to reduce the adverse effects of mycotoxins on the sow body. (4) Strengthen the prevention of bacterial and viral diseases in sows, such as porcine blue ear disease, circovirus and porcine pseudorabies.

2. sows prenatal, postpartum dyspnea:

1. Causes of the disease: Especially in summer, sows have more symptoms of prenatal and postpartum dyspnea, mainly abdominal dyspnea and non-eating. The clinical diagnosis is mainly the mixed infection of circovirus and Haemophilus, which is more serious, and the casualties caused by sows are also relatively large. 2, prevention and control measures:(1) to strengthen the vaccination and feeding management. (2) It is strictly prohibited to feed moldy feed, and mildew removal agent (mold removal No. 1) and vitamin C powder can be added to feed and drinking water. (3) In order to effectively prevent the secondary infection of respiratory diseases in pigs, the feed can be added: Qizhen Zengli Granules, Ligao Ratai and Florfenicol powder, fed continuously for 7-10 days per month, with significant effect.

3. sows postpartum constipation:

1. Characteristics of the disease: great physiological changes have taken place in sows after giving birth, especially the sow's physiological vitality is greatly injured and its body overdraft is relatively large. In particular, the digestive organs are abnormally active after being squeezed, and their ability to absorb water from intestinal contents is enhanced. If the feeding and management are not scientific, constipation will easily form, and even lead to sows not eating, abdominal distension, fever, pulling "counting plate" like feces, some can be as long as a month. Severe cases lead to the cessation of lactation of sows, seriously affecting the development of piglets.

2, prevention and control measures:(1) increase sow activity, promote digestion. As the saying goes: life is movement! For animals is no exception, the right amount of exercise can promote gastrointestinal peristalsis, increase the secretion of digestive juice, is conducive to the formation of feces smooth discharge. (2) more than 10-15 days after birth to green juicy feed, or add 2%-4% vegetable oil to the feed to increase intestinal lubrication. (3) Adjust the feed formula, add some bran in the diet, because the bran is rich in phytate phosphorus, has a mild diarrhea effect; for constipation also has a good regulatory effect. (4) Sows with severe constipation can add some magnesium sulfate to the feed. Due to osmotic pressure, the intestinal cavity keeps a large amount of water, stimulates the intestinal wall to enhance peristalsis, softens feces and promotes diarrhea. (5) After giving birth, sows cannot feed a large amount of food at one time. Due to postpartum fatigue, the body is seriously overdrawn, the gastric motility is insufficient, and the digestive function is reduced; at this time, it is necessary to feed more meals, increase more liquid food, and drink more The clean water of carbohydrates is conducive to digestion and absorption, and is more conducive to the role of strengthening the stomach and widening the intestines. When feeding the feed, it should be gradual and gradually increase the feeding amount until the normal feed intake is restored. (6) for sows postpartum fever or postpartum infection, especially postpartum high fever does not retreat, easy to cause constipation, sows postpartum fever, must be quickly cured. Otherwise, it will lead to the reduction of lactation or milk quality of sows, and even the complete cessation of lactation.
