Poisoned...

Signs before farrowing:

1. Changes in breasts and nipples: sows begin to have obvious boundaries between the base of breasts and abdominal wall 15-20 days before birth. As the expected date approaches, breasts gradually swell and sag from back to front. About 3 days before birth, the nipples open outward. When the nipples on both sides are extremely swollen, the skin is tense and red, the nipples are arranged in an A-shape and shiny, and sometimes there is a small amount of grass sticking to them (this phenomenon is not obvious on the birth bed), it is a sign that they are about to give birth.

2. Changes in milk in nipples. About 3 days before birth, the middle two pairs of nipples can squeeze out a small amount of clear liquid. About 1 day before birth, 1-2 drops of white colostrum can be squeezed out. About half a day before birth, the front nipples can squeeze out 1-2 drops of white colostrum. When the last pair of nipples can gently extrude thick, threadlike colostrum, it is a sign that the baby will be born.

3. Changes in the vulva: 3-5 days before birth, the vulva begins to swell and gradually flush. A few hours before birth, most sows shed a small amount of mucus. When the sow lies on its side, its tail wags, its anus begins to nudge, and most sows shed blood-red fetal fluid, it is a sign that they will give birth.

4, changes in the pelvic part, sow in 7-14 days before birth, pelvic ligament began to soften, to 12-36 hours before birth, ligament rear edge becomes very soft, shape disappeared around the tail root soft, until the tail root collapse, that is, the sign of the upcoming birth.

5, frequent defecation urine, sow 6-12 hours before delivery, began to discharge persimmon shaped soft feces, urination times increased, the closer to delivery, persimmon shaped soft feces from large to small, urination times from less to more, urination volume from variable less.

6. Mental state: sows begin to be depressed and restless about 12 hours before birth. The closer they are to labor, the more irritable their temperament is, and the more frequently they lie down from time to time.

7, appetite, sow about 12 hours before birth began to lose appetite, close to labor is no appetite.

Through the above points, we should have a certain understanding of the signs before sow delivery, as long as the above three signs appear, it will be the sign of farrowing.

Prenatal vomiting in sows may be caused by wind, drug poisoning, too much prenatal feeding, etc. From the color of sow vomiting, sow itself a little stomach disorder, sow weakness, intravenous glucose should be injected to supplement sow ability, and then oxytocin oxytocin. This can be avoided by halving the amount of feed given to sows 3 days before parturition!
