The economic benefits of the farm depend mainly on the production capacity of the sow. The sows with high production capacity and healthy piglets can bring benefits to the pig farm. If the sow has low production capacity and the piglet mortality rate is high The economic benefits are bound to be bad. However, in the breeding process, due to the insufficient management of the pigs by the farmers, the sows are delayed or difficult to produce during the production process. The sluggish production and dystocia severely restrict the production capacity of the sows. If not solved in time, the breeding will be carried out. The household brings a certain economic loss. So how do farmers distinguish between delayed production and difficult production? How can farmers solve the problem of delayed production and dystocia?

First, the difference between delayed production and dystocia

Stagnation of sows is that the sows have a labor period of more than 5 hours. The reason for the sows' sluggishness is mainly due to the lack of production, uterine contraction, weakness and physical weakness caused by prolonged sub-health status.

The dystocia of sows is caused by the inability to produce normally. Many of them are caused by improper management of the sows in the later stages of pregnancy or the sows themselves, such as excessive fetal growth caused by improper feeding, congenital cervical stenosis of sows, Uterine malformation, fetal position is not correct. Farmers often cannot correctly distinguish between delayed production and dystocia. Therefore, the lack of appropriate measures in assisting production has caused a decline in the productivity of sows, which has brought certain economic losses to the pig industry.

Second, how do farmers judge delayed production and dystocia

In the case that the next piglet is not delivered within 20-30 minutes after the sow has produced one or two piglets, the farmer can use the vas deferens to detect the position of the next piglet to determine whether the sow is stagnation or dystocia. Insertion of the vas deferens into the birth canal 25-35 cm before touching the piglets proves that the piglets are still in the womb's uterus, so it can basically be judged to be delayed; if the vas deferens is inserted 10-25 cm, the piglet is touched. Piglets can be judged to be dystocia in the birth canal or in the cervix.

Third, the method to solve the problem of delayed production and dystocia

If the sow has a delayed production during the production process, it can be used to promote sow production. If the sow is dystocia in the production process, it can be taken, push, pull, sputum and other measures to assist the delivery. The midwife's arm should be sent to the rear of the birth canal after it reaches the piglet, but it must be disinfected beforehand.

If the number of stagnation and dystocia in the pig farm is relatively large, it proves that the sows in the pig farm have serious sub-health, and the farmers should adjust the sow movement in time to improve the sub-health. In the production of sows, the farmers only have a precise distinction between the sows that are stagnation or dystocia, so that they can take correct measures and methods to help the sows in the production of the sows, otherwise they will not help the sows to produce piglets smoothly. This can cause serious economic losses to the farm due to the death of sows and piglets.
