Cause analysis and treatment of delayed delivery in sows

Sow delivery

The postponement of sow delivery and premature delivery of sows are abnormal production phenomena that often occur in the process of pig production. The emergence of this phenomenon will more or less affect the results of sows giving birth, resulting in varying degrees of economic losses. Therefore, to correctly deal with the problem of delayed delivery of sows, we need to pay attention to the following five aspects:

1. Strengthen the management. Prenatal observation of parturient sows is carried out every day to check the fetal movement of embryos. Special attention should be paid to the feed intake of prenatal sows, which is a direct response to the health status of sows. If you stop eating a few days before delivery, the sow may have a cold or fever and need to be diagnosed and treated in time. If it has nothing to do with the disease, it is likely to be a sign of labor and needs to be screened.

2. Check the breeding records. When it is confirmed that the mating records are accurate, active measures can be taken to promote sow delivery. Chloroprostol is recommended instead of oxytocin. Oxytocin should be used during sows giving birth, and pay attention to the use of appropriate doses.

3. Adjust the delivery time of sows. The drug, Chloroprostol, is used to treat parturition during 112Mel 113 days of pregnancy at 10:00 every day. Sows usually give birth after 20 Mel 30 hours, which encourages 85% of sows to give birth during the day and is easy for breeders to care. to prevent stillbirth and dystocia.

4. Due to many causes of dead fetal mummies, insufficient nutrition (sows stopped feeding prematurely), sows ate moldy feed, and sows were infected with Japanese encephalitis virus, parvovirus, pseudorabies, swine fever and so on. Therefore, the feed quality should be strictly controlled and the comprehensive prevention and treatment of the above diseases should be done well.

5. It is necessary to find out the delay of delivery as soon as possible, and it is also a positive and effective way to reduce the loss. If the breast is found to develop well in the early stage, and the phenomenon of returning milk occurs before the due date, it is necessary to pay special attention and take necessary observation measures.
