What to do if sows don't eat for a long time and are prone to abortion if they don't eat low temperature before delivery?

The prenatal body temperature of sows is lower than 38.5 ℃ or tends to be normal, such as loss of appetite, constipation, reduced frequency of urination, like lying, reduced food intake, depression, refusal to eat, lying on the ground, such as not eating for a long time can lead to abortion, weak fetus, stillbirth, and even maternal death. So how to prevent sows from prenatal fasting?

First, the reasons:

1. Lack of exercise. Sows raised in the positioning column, can not move normally; especially in the late pregnancy sows crawl for a long time, do not want to exercise, coupled with the fetal size becomes larger, oppressing the digestive tract, resulting in intestinal peristalsis slow down, causing sows not to eat.

2. Lack of energy. Resulting in the decline of sow resistance, coupled with the increase of stress factors resulting in metabolic disorder, resulting in sow physical weakness, causing no food.

3. Lack of light. In winter, the pig house is airtight, the pig is less exposed to the sun, the house is cold and humid, and the environmental hygiene is poor, which causes endocrine disorders, which leads to digestive dysfunction and hypothermia.

4. The proportion of nutrition is seriously out of balance. In particular, there is a serious imbalance in minerals, trace elements and vitamins, which causes digestive disorders in sows and leads to loss of appetite or heterophilia.

5. Endocrine disorders in sows cause exuberant deficiency fire and slow gastrointestinal peristalsis, which leads to constipation.

Precautionary measures:

1. Strengthen the management of pregnant sows, especially perinatal sows. Pregnant sows should be fed with special feed to prevent feed mildew, especially in the later stage of pregnancy, adequate vitamins and minerals and other nutrients should be provided.

2. Strengthen environmental regulation and control to reduce cold stress. Pig farms should pay attention to temperature control. Protect against cold and warmth in winter to provide a suitable environment for sows.

3. Exercise properly. Sows can reduce exercise and keep quiet during 1-3 weeks of mating and 1-2 weeks before parturition to prevent miscarriage or premature delivery caused by accidental stimulation. However, in the second trimester of pregnancy (20 days after mating to 100 days of pregnancy), sows should be given proper exercise and light, which is conducive to fetal development.

Treatment:

1. Pregnant sows with normal body temperature: intramuscular injection of progesterone 60 mg and 10 ml compound VB to improve digestive function and promote appetite, once a day for 2-3 days.

2, for hypothermic pregnant sows: (1) first intramuscular injection of 10% sodium camphor sulfonate 1 gram, raise the body temperature, rise to normal, stop using. (2) intramuscular injection of progesterone 60 mg calming fetus and 10 ml compound VB to improve digestive function and promote appetite. (3) then intravenous infusion: 10% glucose water 500ml + 10ml VC+ inosine 600mg + ATP40 mg; 0.9% saline 500ml + ceftiofur (5mg / kg body weight), once a day for 3 days, the sow can be cured.

3. Traditional Chinese medicine therapy: take Codonopsis pilosula, astragalus, cinnamon, cooked aconite 25 grams each, dried ginger, grass fruit, forsythia, roasted licorice 15 grams each, grind into fine powder, and brown sugar 300 grams, add 1 liter of water, fried to 500 milliliters, warm after filling sick pigs. Once a day, one dose a day, three consecutive doses. Adenosine triphosphate 50 mg was injected intramuscularly once a day for 3-5 days.

4. Sows with dry stool and low body temperature: enema with soapy water. After excretion, 10 ml compound VB and 10% sodium camphor sulfonate are injected intramuscularly, once a day for 2-3 days. Properly strengthen exercise, you can feed more green succulent feed.
