What if your domestic sow is not born at the time of production or the production process is particularly long? what is the reason? Any treatment therapies? The labor process is the process of sow production. It is the time interval from the first pig's birth of the sow to the total discharge of the placenta. The sow's labor process is normal for about 3 hours. How long is your sow's labor?
Three reasons for pigs' long labor and prevention methods
1, the productivity is too small, the sow in the production process, relying on the contractile force generated by the abdominal wall muscle, diaphragm and uterine smooth muscle, the pig fetus and appendages are forced out of the uterus, the sows fed in the limit bar are more It is prone to insufficient contractility. Abuse of oxytocin and cloprostenol may also cause the uterus contractility of sows to be weakened. It is not a last resort. Do not use piglets by hand to increase the elimination rate of sows. Infusion (replenishment of energy) in the production process, massage the breast (stimulation of the sow itself to produce oxytocin), uterine perfusion to promote the contraction of uterine smooth muscle.
2, the birth canal is too dry or too narrow, the sow in the limit bar sports insufficient, blood circulation is not good, often appear thinner, less amniotic fluid, resulting in long sows, can be given to the mother three days before the birth of the sow Pigs feeding some traditional Chinese medicines that improve blood circulation will have certain effects. When selecting seeds, choose sows with wide crotch and moderate muscles of the buttocks. Choose sows with larger abdomen to keep pigs, and delay the first time of sows. Breeding time, if the sow is too small, the development is not complete, and dystocia may occur.
3, pigs are too large and low in vitality. In the production process, if the pigs have better vitality, they will instinctively struggle with the birth canal, and the labor process will be shortened. If there is stillbirth in production, the labor process will inevitably increase, and even cause Pigs are stranded, and some farmers think that the bigger the piglets are born, the better they will be raised in the future. In fact, this is not the case. The sows will increase their body weight by more than 60% in the last month of pregnancy. Some farmers will give The sows are fed in large quantities, which leads to a significant increase in the difficulty of sows. Many piglets with large birth weights become weak ones because they have no strength to eat milk. They can supplement the sows with nutrition for about 20 days. This can effectively improve the vitality of piglets and thus shorten the labor process.
In fact, the long-term hazard of sows is too much. According to the data feedback from the scale farms, the sows have too much physical exertion, the uterine inflammation is aggravated, and the sows have decreased postpartum feed intake, less milk, repeated infertility, and piglet diarrhea. Etc., so the smooth process and shortened time is also a place to pay attention to. These reasons and suggestions are for reference only. The specific reasons are better based on the actual situation of the pig farmers. For more relevant agricultural technology knowledge, please pay attention to Rural network!
