There are many reasons for lactation in lactating pigs. The proportion of sow lactation disorders in the mortality rate of newborn piglets is quite high. Piglets who do not have enough breast milk will starve to death, squat or die due to weakness. The most prominent phenomenon of sow lactation disorder is that the sow's breasts reduce lactation or secrete thin water-like milk. If not treated promptly, it will cause long-term estrus, abnormal estrus and reduced litter size, and the disease. Piglets born to sows are also often poorly developed and die.   I. Analysis of the causes of lactation disorders in sows 1. Nutritional factors. The various stages of sow pregnancy are caused by improper feeding or improper feeding, which leads to the condition of being too thin or too fat to cause the disease. In addition, sudden replacement of feed by sows leads to digestive disorders, which can also result in reduced feed intake, which affects sow lactation due to inadequate nutrient intake. Reduced drinking water in sows can also lead to decreased feed intake, which can easily induce constipation and mastitis, leading to lactation disorders. 2. Environmental factors. The space in the delivery room is too small, poor ventilation, lack of light, easy to be disturbed by noise, high concentration of harmful gases or strict cleaning and disinfection of the bed, which can cause inflammation of the breast. Sows often lie on wet ground, and poor sanitary conditions can easily lead to infections in the nipple and birth canal; breast and nipples that are not cleaned and disinfected during labor can also cause lactation disorders. 3. Stress factors. The sows are transferred to the labor bed one week before the birth, and the lactation is affected by changes in the environment, too much tension during childbirth, excessive physical exertion, and too long a childbirth. In addition, pregnant sows are suddenly frightened or rude, and pre- or lactation is prone to stress due to injections of antibiotics or vaccines, as well as during the lactation, which can cause sows to become lactating. Second, the clinical symptoms of sow lactation disorders Sows show depression, loss of appetite, normal or slightly elevated body temperature, discharge of dry hard dark brown globular feces, and a few sows with severe symptoms will shed feces with yellow-white mucus or blood clots; multiple breasts appear solid swelling Lactation disorders, sometimes accompanied by obvious red hot and swollen breasts, so the sow will refuse to suck the piglets. If the sow is milk-free or can only discharge a small amount of thin, nutrient-free milk, or the breast is severely swollen, the blue veins are prominent and the skin is bright. Some sick pigs are accompanied by symptoms of urgency, frequent urination or urinary excretion. If you do not control it in time within 3-5 days, it will easily cause breast gangrene, which can lead to systemic infection, rapid increase in body temperature, stop eating and completely lose breastfeeding ability. Third, the prevention and treatment measures for sow lactation disorders 1. Strengthen feeding management. Sows should be fed a good quality full-price compound feed during pregnancy, and also fed a certain amount of green and juicy feed to prevent over-fertilization. It is forbidden to feed too much concentrate before giving birth to avoid constipation after birth; proper restriction feeding should be taken before birth to prevent the sow from affecting lactation after birth, and to inhibit the occurrence of mastitis; Gradually increase the amount of feeding, after a 7-day transition to be able to feed in the normal amount. 7 to 10 days before the delivery of the sow, it is necessary to ensure that the sunbathing takes about 2 hours a day. Adhering to moderate exercise is beneficial to the delivery and improving the lactation function. 2, drug prevention and treatment. Sows can be fed Chinese medicine preparations 2-3 days after delivery, generally choose to use Yimu Biochemical Powder (main ingredients are motherwort, peach kernel, safflower, angelica, etc.), with Wenjing analgesic, promoting blood circulation, tonifying qi and blood Its role can accelerate the recovery of postpartum uterus, stimulate milk secretion, but also has a good effect on postpartum prone to endless dew, fetal dressing, blood deficiency, blood stasis and abdominal pain. Each time you use 100-150 grams, add appropriate amount of boiling water to soak or add water to cook, then add 250-300 grams of brown sugar and 58 grams of calcium hydrogen phosphate in the liquid medicine and mix them evenly. The remaining dregs can be added to the feed. Use for 3 consecutive days once a day. In addition to prone to lactation disorders, postpartum sows may also develop diseases such as mastitis and metritis. These diseases also cause a decrease in lactation in sows.
