Breastfeeding sows do not eat too much solution
During the last 15 days of pregnancy, if sows are exposed to high environmental temperatures, it can lead to reduced feed intake, even complete loss of appetite. This can result in weak piglets, stillbirths, or dystocia, and may also cause uterine endometritis in the sow. If not managed properly, this can lead to prolonged estrus or even death after weaning, which negatively impacts overall production efficiency. Here are some effective solutions:
**Proper Feeding Management:**
(1) About 15 days before farrowing, switch sows to a lactation diet that is high in energy, protein, and amino acids. Increase moisture content by feeding wet mash, which improves palatability. You can also add vitamins A, D, and E to enhance nutritional value. (2) Ensure that sows have access to sufficient fresh water every day, and monitor their intake carefully. (3) Use high-quality feed and include mycotoxin binders to prevent contamination. Always clean feed troughs regularly and avoid leaving leftover feed.
**Timely Assistance During Birth:**
The normal interval between births is around 30 minutes. (1) In cases where the birth canal is normal, administer 10–20 units of oxytocin intramuscularly to stimulate contractions. (2) If the fetus is too large or the birth canal is narrow, and two fetuses are being delivered at once, consider using artificial assistance or performing a cesarean section promptly. (3) Handle all other birthing situations with care and timely intervention to ensure safe delivery for both sow and piglets.
**Postpartum Care Plan:**
(1) Administer antibiotics intramuscularly 2–3 times after birth to prevent infections. (2) Give oxytocin injections to help the uterus contract, open the cervix, and expel any remaining material, reducing the risk of endometritis. (3) Wash the uterus with a diluted potassium permanganate solution to maintain hygiene. (4) Due to the physical strain during labor, sows may experience weakened digestion. It’s best to withhold feed on the day of birth but ensure they have constant access to clean water.
**Environmental Control:**
Ensure adequate drinking water and improve ventilation to lower the temperature inside the barn. Sows need more water during hot weather—ideally, a feed-to-water ratio of 1:3, and up to 1:4 or 1:5 during heat stress. A nursing sow typically consumes 12–40 liters of water per day, averaging about 18 liters. In extreme heat, this can increase to 30 liters daily. Insufficient water intake can severely affect feed consumption and the sow’s ability to regulate body temperature. Providing enough water is essential for maintaining health and productivity.
