Breastfeeding sows do not eat too much solution

Pregnant sows that experience high environmental temperatures about 15 days before farrowing are at risk of reduced feed intake, or even complete loss of appetite. This can lead to weak piglets, stillbirths, and complications such as dystocia and uterine endometritis. If not properly managed, it may also result in prolonged estrus or even death after weaning, which negatively impacts overall productivity. Here are some effective solutions: First, adjust feeding practices. About 15 days prior to farrowing, transition the sow to a lactation diet, and increase the moisture content in the feed by using wet mash. Provide energy-dense, protein-rich, and amino acid-enhanced diets to improve palatability. You can also add vitamins A, D, and E to support reproductive health. Ensure that sows have access to clean, fresh water throughout the day. Use high-quality feed and treat it for mycotoxins. Always remove leftover feed promptly to prevent spoilage. Second, perform timely assistance during farrowing. The normal birth interval is around 30 minutes. In cases where the birth canal is clear, administer 10–20 units of oxytocin intramuscularly. If the fetus is too large or the birth canal is narrow, or if two fetuses are delivered at once, consider artificial assistance or a caesarean section. Proper and timely handling of all births is crucial to avoid complications. Third, implement a postpartum treatment plan. Administer antibiotics intramuscularly 2–3 times after delivery to prevent infections. Oxytocin injections help stimulate uterine contractions, relax the cervix, and promote the drainage of residual material, reducing the risk of endometritis. Wash the uterus with a diluted potassium permanganate solution. Due to the physical strain of farrowing, sows often experience weakened digestion, so they should not be fed on the day of birth. However, ensure they have plenty of clean drinking water and maintain good ventilation to lower the temperature inside the barn. Under normal conditions, the feed-to-water ratio for gestating sows is 1:3, and can increase to 1:4 or 1:5 during hot weather. Nursing sows typically consume 12–40 liters of water per day, averaging around 18 liters, but this can rise to 30 liters during high temperatures. Insufficient water intake can severely impact feed consumption and hinder the sow’s ability to regulate body heat. Therefore, ensuring adequate hydration is essential for both maternal and fetal health.
