Sows reduce postpartum food and milk countermeasures

The sow from Pingming Township, Donghai County, recently gave birth to 16 piglets. She had been eating well before farrowing, but in the last few days, her feed intake dropped to about 50% of normal. Additionally, she had insufficient milk for four consecutive days. The sow maintained a normal body temperature after giving birth and showed no other signs of illness. The farmer is concerned about what might be causing this situation and is seeking advice. From the description, it seems unlikely that the reduced appetite and low milk production are due to infectious diseases. More likely, the issue stems from nutritional imbalances or postpartum exhaustion. Poor nutrition during pregnancy, an over-reliance on concentrated feeds after farrowing, and a lack of green, juicy feed and fiber can all contribute to reduced appetite. Additionally, if the sow experienced complications such as retained placenta or stillbirths, this could also lead to loss of appetite. To prevent such issues, it's important to provide pregnant sows with balanced, easily digestible feed without excessive fat. The diet should include a proper mix of roughage with 8-12% crude fiber. In the last 30 days of gestation, ensure sufficient green feed is available, while paying attention to the calcium-to-phosphorus ratio, salt content, and vitamin levels. High-yielding sows benefit greatly from diets rich in calcium, phosphorus, and vitamins to support recovery after farrowing. In the five days leading up to farrowing, gradually reduce concentrate feed and increase green feed. Encourage the sow to exercise before labor to improve her physical condition and aid recovery. After giving birth, monitor her intake of salt, vitamins, calcium, and phosphorus. On the day of farrowing, offer a light, easily digestible feed. For the first 1–3 days postpartum, limit concentrate feed, then gradually increase it starting on day 4. Add oral electrolytes to drinking water to help maintain hydration. Promptly treat any postpartum fatigue to avoid complications like retained placentas. For treatment, if the problem is caused by excessive concentrate, mix 250g of rice wine, 200g of brown sugar, and 100g of ginger and feed it to the sow. If the issue is due to calcium or phosphorus deficiency, administer 5g of calcium gluconate three times daily for 5–10 days, or 30g of bone powder twice daily for 5–7 days. Intravenous calcium gluconate (10%) at 300ml once daily for 3–5 days may also be effective. To address weakness, give intravenous glucose, vitamin C, ATP, and Coenzyme A, along with daily injections of vitamin B1. To stimulate appetite, mix 100g of yeast powder, 20g of artificial salt, and 20g of Jianqu in 1.5kg of water and administer via a stomach tube once daily every 2–3 days. Low milk production is often due to poor nutrition, monotonous feed, or inadequate postpartum care. Early mating can also affect mammary development, and older sows may experience reduced milk production. To improve milk supply, adjust the diet to include more green and succulent feed. Use traditional Chinese medicine like Astragalus membranaceus and Wang Fulao, each 200g, given through a gavage once daily for 3–5 days. One month postpartum, feed a mixture of 0.5kg of seaweed, 100g of animal fat, and 5kg of water boiled for one hour, divided into seven portions and fed daily. If milk is still low, inject 500–1000 IU of prolactin subcutaneously twice. Alternatively, mix 100g of Angelica sinensis, 50g of Tongmu, and 500g of fresh willow bark with millet porridge. When there are 16 or more piglets, and milk supply is insufficient, consider cross-fostering and improving the sow’s nutrition. Use high-energy, high-protein feeds such as 50% corn, 10% soybean meal, 10% fish meal, 27% bran, and 3% animal fat. Fresh quail can be cut into small pieces, cooked, and mixed with brown sugar to feed the piglets 1–2 times daily, around 250g per feeding.
