Sow farrowing fortune telling

Generally speaking, it is "three three three", that is, three months (according to 30 days), three weeks and three days. Average 1 14 days. However, pregnancy is affected by many factors, such as variety, age, health, nutrition, management, etc., such as slipping and squeezing. Therefore, some people give birth earlier or later 10 days.

Diagnosis of pregnant sows in childbirth

Look at breasts: as the saying goes, "nipples explode and will soon fall off." During the period from 0/5 to 20 days before delivery/kloc-0, the sow's breast gradually swelled and drooped from back to front, and its base swelled in the abdomen, showing two bands. The breast skin is tight and red, and the nipples on both sides are splayed outward in a figure of eight. About 6 hours before delivery, thick yellow-white milk can be squeezed out. As the saying goes, "milk wears an arrow shaft, and childbirth is not far away." Under normal circumstances, clear milk can be squeezed out 2 ~ 3 days before delivery. Sows may give birth about 24 hours after thick milk appears in the front nipple and 3 ~ 6 hours after thick milk appears in the middle nipple. If you gently squeeze each nipple with your hands, you can milk it, or at last 1 when you can milk the breasts, you will give birth.

The baby will be born soon. But there are also some sows that secrete milk after giving birth.

Second, look at the vulva. 3 ~ 5 days before sow labor, vulva begins to swell and droop, and both sides of tail root are sunken, which is a sign of pelvic opening. At the same time, the frequency of excreting feces and urine increased. If the vulva is loose, red and swollen, and there is mucus flowing out, it is a sign of quick delivery. When the vagina oozes thin bloody mucus, it means that the sow has "broken water" and will give birth within 30 minutes, that is, as the saying goes, "The sow urinates frequently and the delivery is coming."

Third, look at the number of breaths. Breathe 54 times per minute 1 day before delivery and 90 times per minute 4 hours before delivery.

Fourth, the behavior shows that sows are nervous 6 ~ 12 hours before labor, which is often manifested as fidgeting, nervousness, loss of appetite, walking back and forth in the house, and some picking grass to build nests; When there is no grass to pick, you will arch the ground with your mouth, and your front hoof is like a nest. The protective sows become rude, keep people away, and some bite people. Don't approach strangers at this time, and don't change people casually.
