We know that piglets are only sold after being cultivated in pig farms. Many new pig farms choose to start with piglets and then raise them after self cultivation. However, many pig farmers find that many piglets show unhealthy conditions when they are introduced, which leads to our later cultivation even if we use pig equipment to raise them It can't play a good role, so why does this happen? In summary, there are several factors that may cause piglets to be unhealthy.
1. Sows start breeding early
As the first born sows are still in the development process, they do not reach the physiological body maturity and sexual maturity, and early mating pregnancy, then they tend to present a relatively narrow birth canal at the time of labor. If the uniformity of piglets is poor, it is very simple to present dystocia, long birth process, resulting in fetal anoxia. In order to reduce the occurrence of this situation, first of all, sows should be mated in time, and only when their weight and age are qualified can they be mated; secondly, in production, it is necessary to pay attention to the first time sows do not attack the fetus too early. It is necessary to adjust the feeding amount and the time of embryo attack reasonably according to the condition of fat body.
2. Constipation causes
The first is compression. When sows are constipated, the hard fecal ball in the rectum directly compresses the birth canal, resulting in poor uterine blood flow, uneven delivery of nutrients, and deterioration of the internal environment of the uterus, eventually resulting in poor uniformity of newborn piglets, or even stillbirth. The second is blocked absorption. The constipation of sows leads to the gradual accumulation of feces in the intestines, which causes the toxins in the feces to be absorbed by the intestines, which will lead to the failure of the detoxification function of the liver and the detoxification function of the kidney, and then the function of the heart and lung will be reduced. However, the sow needs a lot of physical strength to give birth. When the function of the lung is poor, the oxygen supplied to the uterine muscles will be reduced, thus increasing The probability of dystocia will eventually increase the probability of stillbirth.

3. Use of oxytocin in Midwifery
We know that long-term dystocia will lead to the risk of the mother, so many pig farms will use oxytocin when the sow is giving birth to the piglet, but we should know that oxytocin is very bad for the piglet. Oxytocin can excite the smooth muscle of the uterus. Although it has the effect of promoting the temporary labor, due to the shortening and increasing, the probability of dystocia of the first-time sow is relatively high, which simply causes the stillbirth It happened. In fact, when the piglets reach the pelvic opening and squeeze the birth canal, the hypothalamus will excrete oxytocin, shorten the smooth muscle of the uterus, and promote the fetus to enter the birth canal. The sows will take the initiative to generate propulsion, which will affect the release of oxytocin in the hypothalamus again and again. The release of oxytocin is of low dosage, very safe, and effectively affect the shortening of the smooth muscle of the uterus. Other piglets also produce oxytocin one after another At the same time, we can massage the breasts of sows to let the piglets after birth. Their sucking and massage can affect the release of oxytocin. Therefore, the use of oxytocin must be careful, not necessarily.
4. Delivery room temperature not suitable
If the temperature of the pig house is too high, it may cause the sow to have clinical symptoms of dyspnea when giving birth. This is because the sow does not have sweat glands, and usually uses breathing and fecal discharge to reduce the body temperature. When sows were born with dyspnea, the blood oxygen concentration decreased, the supply of oxygen to uterine muscles decreased, and the contractility of uterine muscles decreased.
5. Long time limit
With the use of limit bars, sows are seriously lack of exercise, and their physical strength, endurance and muscle contractility are greatly reduced. Sows often have a long labor process, and are prone to show symptoms of uterine contraction weakness, increasing the incidence of piglet death.
6. Improper time for group transfer
When the sows are transferred from the pregnancy house to the delivery house, due to the conditions of the house (such as the slippery ground and the high connection between the bed and the ground) and the lack of patience of the employees, the sows are treated violently or the sows fall down, resulting in the damage of the machines and the stillbirth.
7、 Improper feeding
After each feeding, clean the surplus feed in the feed tank, the rest of the feed will easily lead to mildew, and mycotoxin will lead to fetal edema and death in the uterus.
8. Disease causing
Reproductive disorders such as subtle, blue ear, ring, pseudorabies, JE, chlamydia and so on may form intrauterine fetal death. Therefore, the basic immune work of sows is also an important way to effectively reduce the generation of stillborn or weak offspring.
All the above eight points are likely to lead to poor health of piglets. When we introduce piglets, we should check their physical condition carefully, and we should ensure that when we introduce piglets, they are healthy piglets introduced from regular pig breeding farms, so that they can have a more perfect guarantee for their health.
