What are the preventive measures for miscarriage in sows?
People who raise sows are relatively afraid of the phenomenon of miscarriage in sows. Miscarriage is a type of abortion, and there are many causes of miscarriage in sows. So how should miscarriage in sows be prevented? Follow the editor to learn about it.
1. Timely mating
Sows begin to ovulate 24 hours after estrus. From the perspective of estrus behavior, there is a change from excitement to a quiet state, and white stringy mucus will flow from the vagina. When the sow's back is pressed with a hand, the sow will stand still without moving. This is the best time for mating, which can reduce embryo mortality and increase the farrowing rate.
2. Strengthen management before conception
From 3-14 days before mating, increase protein feed and energy feed, and at the same time add minerals and multiple vitamins, so that they quickly enter the mating state. For thinner sows, strengthen nutrition for a relatively long period before mating, and restore their previous physical strength as much as possible, so as to facilitate mating, conception, and fetal protection, and increase the farrowing rate.
3. Pay attention to feed quality
Do not feed pregnant sows moldy, frozen, or otherwise contaminated feed, otherwise poisoning is very likely to occur. In mild cases, it causes embryo death; in severe cases, it affects the sow's life safety.
4. Appropriate exercise
If sows do not exercise regularly during pregnancy, the embryo mortality rate is about 0.5% higher than that of sows that exercise regularly. The exercise method for sows is mainly free movement. During exercise, pay attention to preventing sows from falling or colliding with obstacles, so as not to harm the embryos.
5. Maintain environmental temperature
During the first week of pregnancy in sows, when the environmental temperature reaches 32-35 degrees for a short time, the embryo mortality rate will increase. Similarly, if a boar affected by heat is used for mating, it will also increase the embryo mortality rate. Therefore, it is best to control the environmental temperature between 15-25 degrees.
