Sows do not eat lactating piglets lose weight how to solve the problem of postpartum fasting in sows

Prenatal and postpartum fasting of sows is one of the common diseases of sows during lactation, which mainly refers to loss of appetite or even abandonment of sows during lactation. Once it happens, the lactation function of sows decreases, the lactating pigs have diarrhea, the resistance is weakened, the growth is slow, and even the pigs become stiff or die of exhaustion; or they lose weight because of stubbornly refusing to eat, lack of estrus after weaning, or although they can mate, they give birth to a low number of offspring, or long-term infertility.

Sow

1. The cause. Gastrointestinal dysfunction caused by blue ear disease and circovirus is one of the main reasons for sows not eating. Mycotoxin aggravates blue ear disease and circovirus, causing double infection. It is caused by malnutrition, stress, insufficient water supply, poor water quality, improper postpartum nursing, postpartum infection pathogenic microorganisms and so on.

two。 Prevention and treatment. Strengthen sow feeding management and environmental control, prevent heat and temperature, clean and hygienic, smooth ventilation, avoid group alarm and reduce noise. Check the drinking water system regularly to provide adequate clean drinking water. Do a good job in immunization, take immunity as the lead, and strengthen the disinfection work. It is forbidden to feed moldy and spoiled feed. In view of the phenomenon of few births, repeated infertility, postpartum and non-estrus in sows, Muduqing can be added to the feed to improve the rate of birth and estrus. Strengthen the prevention of blue ear disease and circovirus, regularly feed Tuomojing and increase immunity and detoxification, once a month, each time for 7 days.

3. It is difficult for sows to breathe before and after delivery. Abdominal dyspnea, not eating mainly. It is suggested to give priority to prevention, first, to strengthen feeding management; second, to add Mengjing to the feed; and third, to add a-immune nucleic acid regularly to enhance the resistance of sows to reduce circovirus.

4. Postpartum constipation in sows. After parturition, the physiological changes of sows are great, especially the function of digestive organs is extremely active after the degree of extrusion is reduced, and the intestinal water absorption capacity is enhanced, such as improper feeding and management, it is easy to form constipation. Serious, cause no food, abdominal distension, fever, pull "abacus bead"-like feces, stop lactation, seriously affect the development of pigs.

5. Prevention and control methods:

(1) to increase the activity of sows and promote digestion; (2) to give more green and succulent feed 15-10 days after delivery; (3) to add 20.4% vegetable oil to the feed 7-10 days after delivery to increase intestinal lubrication; (4) to add more wheat bran, which is rich in phytic acid and phosphorus, which has mild diarrhea. (5) add proprietary Chinese medicine to the feed to increase lactation, reduce constipation, improve sow resistance, increase lactation, improve milk quality, and reduce diarrhea in piglets; (6) when feeding after delivery, one should not be given a large dose, but should be gradually increased until normal feeding is restored; (7) it is easy to be constipated when having a fever. When sows have a fever, it should be treated in time and cured quickly.
