Pigs can generally give birth to 2 litters per year/kloc-0. The gestation period of sows is generally 1 10- 120 days, with an average of 1 14 days. The sow's breasts will gradually expand from back to front in the first half of delivery. Five days before delivery, the sow's breasts are red and shiny, gently squeezing the back breasts, and a small amount of milk flows out. Sows will lie prone on the ground before giving birth, their limbs will be straight, and the contraction phenomenon will gradually become shorter. When the amniotic fluid flows out, the first piglet can be born.
1. How many litters do pigs have a year?
1, sow 1 can generally give birth to 2 litters of piglets. The reproductive period of pigs consists of pregnancy, lactation and empty pregnancy. The gestation period is generally 1 10- 120 days, with an average of 1 14 days, and the lactation period is one and a half months.
2. In the first half of delivery, the sow's breasts will gradually expand from back to front, and there will be a clear boundary between the base of the breast and the abdomen.
3. One week before delivery, the nipples began to gradually separate to both sides in the figure-eight direction.
4. The sow's breast appears red luster five days before delivery, and a small amount of milk will flow out when the back breast is gently squeezed.
The day before delivery, the milk secreted by sows is mainly yellow and thick. The sow's vulva gradually swells and turns reddish purple in color, and mucus will gradually secrete in the vulva.
6. 10 Prenatal, sows get up frequently, and their vulva is red and swollen. Two hours before delivery, the sow showed extreme anxiety, mainly manifested as shortness of breath, non-stop walking, frequent urination and yellowish mucus from the vulva. When the sow lies on the ground, her limbs are straight, the contraction phenomenon is gradually shortened, and the amniotic fluid flows out, so that she can give birth to the first piglet.
Second, what if the newborn pig can't stand up?
1, squeeze out two drops of milk after the pig, which contains many germs, and then feed it to the pig. If you can't eat milk, the pig will naturally stand up. Helping piglets find nipples and eat enough milk is also the key to their survival.
2. Pseudorabies or mycotoxin can lead to weakness of hind legs and even splayed legs of piglets. For sick piglets, sodium selenite and vitamin E can be used as adjuvant therapy, each head is 0.5 ml,/kloc-0 times a day for 2 days.
3. If a little pig wants to stand but can't, it can be forced to stand. If the piglets are shivering, it is because of the imbalance of calcium and phosphorus. At this time, calcium, phosphorus and vitamins need to be supplemented.
