Breast milk is the main nutrient after birth of the piglets. The quality of the breast milk and the level of yield directly affect the growth and development of the piglets. To ensure the normal development of piglets, effective measures must be taken to ensure that sows have higher milking power throughout the lactation period and prolong the peak period of lactation.
First, feeding skills
1. Ensure appetite. If the sow has no appetite after birth, it will affect the amount of lactation for several days. Loss of appetite is often caused by too much prenatal feeding of sows. Therefore, technical measures should be taken for pre-production reduction and post-production incremental feeding. According to the sow's individual condition, the reduction is usually started 3-7 days before the birth. The sows that are particularly obese can also reduce the material before 7 days; the feeding is stopped on the day of delivery, and the bran water is consumed 6-8 hours after delivery (1 Parts of bran plus 10 parts of water) are fed normally for 3-5 days after birth. Decrease 1/3 of the prenatal day, 1/3 per day; decrease 1/4 per day when cutting materials before 5 days of prenatal; 1/3 decrease every 2 days when materials are cut before 7 days of antenatal period, 1st day of feeding when feeding 1 Kilograms, gradually increased later, added to 3.5-4 kilograms on the seventh day, and adjust after a week of stability.
2. Appropriate feeding of green and juicy feed. The green-blue succulent feed must be fresh and the amount fed should be as low as possible. Night feeding a green feed, has a significant effect on promoting lactation.
3. Feed animal feed. During sow feeding, appropriate feeding of fish meal, bean cake, etc., can increase milk production.
4. Supply plenty of clean drinking water.
Second, strengthen the feeding tube
1. Make full use of the sow's nipple. Having the piglets occupy all of the sows in the sow is especially important for the primiparous sows. If sows do not have enough litter size to take up all the nipples, they should try their best to do both nesting and foster care, or train the piglets to get used to using two nipples. When the sow is feeding, the piglet is rapidly transferred to the adjacent free nipple separately from the nipple it is sucking. This is repeated 3-4 times, the piglet can automatically change from one nipple to another nipple. All nipples are occupied, can promote the rapid development of the mammary gland, and can guarantee the next fetal lactation.
2. Cut off the canine teeth in time. After birth, the piglets should cut off the canine teeth in their mouths in time to prevent biting and biting of the sow's nipples, causing the sows to feel restless and refusing to breastfeed.
3. Maintain a comfortable and quiet environment. The barn should be clean, bright, with proper temperature and humidity, and kept quiet.
4. Good breast massage and care. Massage can promote breast development, increase its production efficiency, and prevent mastitis. The amount of blood in the breast increases during massage, and nutrients enter the tissue in large quantities, increasing metabolism, increasing the tone and contractility of the smooth muscles, and facilitating the milk to be discharged more easily. Before the massage, wash the breasts with warm water (approx. 40°C) and dry them. Then massage the entire surface of the breast from the top to the bottom, and then perform a deep massage for each breast and nipple, at least once a day for about 20 minutes each time. . While scrubbing and massaging the breasts, pay attention to checking whether the breasts are swollen and whether the skin is damaged (scuffs, cracks, scabs, etc.), and then take targeted nursing measures.
