What should sows prepare before delivery?

Sows are the core group of the whole farm, and its reproductive performance determines the productivity level and profitability of a farm. And sow delivery is also a more important job, many people are often at a loss, so what should be prepared before sow delivery? Let's take a look.

1. Estimated time to give birth

After the sows are bred, it is necessary to calculate the expected delivery period of the sows, which is usually "three-three system", that is, three months, three weeks plus three days. Therefore, in breeding households, we must keep in mind the breeding time, so as to estimate the expected delivery period of sows. The average gestation period of sows is about 110-120 days, with an average of 114 days. Therefore, we are generally calculated according to the expected delivery date of 114 days, 4 days in advance and 4 days delay are normal childbirth, so that we can well estimate the birth time.

2. Prenatal observation is necessary.

Before the sow is close to giving birth, it will undergo a series of physiological changes, such as enlarged breasts, redness and swelling, slow movement and so on. Specifically, it must be 5 days before delivery, the sow's room begins to get bigger, bright red, and the nipples on both sides rise. At this time, milk will flow out when squeezed by hand. In the 3 days before giving birth, the sow walks slowly, and the rise and lie down is obviously slow, then touching the breast with the hand will have the feeling of fever. When the sow's breasts are squeezed 12 hours before parturition, thicker children will be extruded. When there is more milk, the sow will give birth within 12 hours. In addition, in the prenatal 6-10 hours, the sow will also find something to make a nest, the forelimbs keep scraping the ground, abnormal behavior, the mouth will make a humming sound.

3. Preparatory work

We should do a good job in the environmental hygiene of the pig house before delivery, keep the environment clean and hygienic, and keep quiet so as not to frighten the sows and cause dystocia. In addition, it is necessary to carry out thorough disinfection and prepare incubators. The sow will be driven to the delivery room before delivery. Scissors, iodine, cloth strips, sticks, shovels, syringes and corresponding drugs need to be prepared before birth, so that all kinds of nursing work can be done for piglets after giving birth.
