What if the labor process of sows is too long?

The whole process of sows from the delivery of the first piglet to the excretion of placenta is called the process of labor. the normal time of labor is 2-3 hours. if the process of labor is too long because of some drinking water, the mortality rate of piglets will be high, which will bring huge economic losses to pigs. So what should we do if the labor process of sows is too long? Let's take a look.

First, the reason for the long process of labor

1. Early mating

If the parturient sows are mating prematurely and their endocrine and reproductive systems are not fully developed, mating will lead to a long delivery time.

2. Reasons for variety

The labor time of some lean sows imported from abroad is 1-2 hours longer than that of local sows, which is related to adaptability.

3. Sow obesity

When the sow is overweight and lack of exercise, its uterine contraction is weak, and it is unable to give birth to the piglets normally, so the delivery time is too long.

4. Causes of parity

Older sows with more than 8 births will show weakness in the later stage of childbirth, uterine contraction and abdominal pressure will be weakened, and the process of labor will often be delayed for many hours, and its litter size will be less and less, and the economic benefit will gradually decrease.

5. Stress factors

Too many babies will make the sow nervous and sensitive. If heat stress and cold stress are added, it will cause it to panic, stand but not lie down, and prolong the process of labor.

6. The cause of disease

When sows suffer from reproductive disorders such as encephalitis, small, and pseudorabies, often in the middle and later stages of pregnancy, the fetus dies in the abdomen, or gives birth to stillbirths or mummies, some as long as 3-4 days or more.

7. Too many fetuses

During pregnancy, the sow is fed overweight, and the fetus grows too much, which leads to the difficulty of sow production and the long labor process.

II. Countermeasures for excessively long stage of labor

Sow first time should not be too early, generally in estrus 1-2 times in breeding, during pregnancy to ensure adequate nutrition and balance, but should not be fed too much, to achieve moderate fat, at the same time to ensure that the right amount of exercise, to develop scientific immunization procedures, effective prevention and treatment of reproductive disorders. Sows should be given birth to create a comfortable, quiet, clean, well-ventilated, temperature-appropriate environment to avoid all kinds of stress. When it is difficult for sows to give birth, they can be artificially induced to give birth. Sows that are old, frail and fertile should be eliminated in time, and young and middle-aged sows should be replaced.
