Last Updated: 2024/11/10, Fertilized eggs cause early death of embryos in the process of development and are absorbed by sows, commonly known as metamorphosis. It is one of the important reasons for the low birth rate, which can be solved by the following methods. 1. Strengthen the feeding management to increase protein feed and energy feed 3-14 days before mating, while adding minerals and vitamins to make it quickly enter the best state of mating; for the poor fat sows, the feeding method of superior feeding can be adopted, that is, it can be strengthened for a long period of time before mating.

Fertilized eggs cause early death of embryos in the process of development and are absorbed by sows, commonly known as metamorphosis. It is one of the important reasons for the low birth rate, which can be solved by the following methods.

1. Strengthen feeding and management

The protein feed and energy feed were added 3 to 14 days before mating, and minerals and vitamins were added to make it quickly enter the best state of mating, and the feeding method of optimal feeding could be adopted for the empty sows with poor body condition. that is, to strengthen nutrition for a long period of time before mating, so that it can restore fat and physical strength as much as possible, so as to facilitate mating, conception, fetal preservation and improve the litter rate.

two。 Timely breeding

The mating time of sows is the best at 22 ~ 24 hours after the beginning of oestrus. From the symptoms of oestrus, sows change from extreme excitement to quieter, white filamentous mucus from vagina, hand pressure on sows' back and waist, sows stand still, the mating time is the best, so the mortality rate of embryos is low and the birth rate is high.

3. Regulate endocrine

Seven days after mating, each sow was injected with progesterone 30 mg intramuscularly, which could effectively reduce embryo death and prevent sows from turning fetus.

4. Improve feed quality

Sows during pregnancy, feed quality should be good, strictly prevent mildew, pollution, frozen feed to feed sows, otherwise prone to food or pesticide poisoning, light cases will cause embryo poisoning death, serious cases will affect the life safety of sows.

5. Control the ambient temperature

In the first week of pregnancy, embryo death increases in sows when the ambient temperature reaches 32-35 ℃ in a short period of time (24 hours); similarly, embryo death can also be caused by breeding with heated boars, so it is best to keep the ambient temperature between 15-25 ℃.

6. Proper exercise

Give priority to free exercise, but to prevent sows from falling.
