In order to improve the fertility of sows, modern pig farms mostly use weaning techniques for 21-day-old piglets. At this time, the digestive function of piglets is not perfect, and the body's resistance is poor. Therefore, it is necessary to strengthen feeding and management in order to achieve an ideal rearing rate. So, how can we raise early weaned piglets? 1. The pig bar is ready early. Nursery stalls are conducive to sanitation and epidemic prevention and feeding and management, and are generally divided into indoor and outdoor sections. The indoor section is equipped with a heat preservation room, a feeding trough and a sleeping bed, and the outdoor section is provided with drinking water devices, sports fields, and excretion sites. Two weeks before the pigs were swept up and disinfected twice with 2 different disinfectants. 2. Settled in groups. According to the size of sex and weight group, generally 10 to 20 heads per column, each head covers an area of ​​about 1 square meter, as far as possible the original group placement. After spraying, disinfect the pigs one at a time to stabilize the pigs and avoid biting. To increase resistance, the piglet can be given an appropriate amount of electrolyte solution (25 g of glucose, 4.5 g of sodium chloride, 2 g of sodium bicarbonate, 0.3 g of citric acid, 0.2 g of potassium acetate, 0.05 g of potassium chloride, add water to 1000 ml) . 3. Use weaning material. Early weaned piglets must be fed with weaning material to minimize the weaning stress of the piglet and promote normal development of the digestive and immune organs. Weaning materials are often prepared from easily digestible raw materials such as whey powder, puffed soybeans, fish meal, plasma protein powder, and fat powder. Acidifiers (such as citric acid) and enzyme preparations (such as protease, amylase, and pectinase) are added. , phytase, etc.), probiotics and oligosaccharides, can maintain the normal micro-ecological environment of the digestive tract of piglets, promote the role of pepsin, improve digestive function and reduce the damage of anti-nutritional factors to the digestive tract. 4, limit feeding not too full. Early weaned pigs weighed 12 kg and were fed with weaning material. They were fed 5 times a day and fed once every 2.5 hours, with 80% fullness each time. After 12 kg in body weight, it gradually transitioned to suckling pig feed. It was fed 4 times a day and fed once every 3 hours. Each time it owed or had just eaten, and there was no residue left. Timing feeding, appropriate limited feeding, is conducive to digestion and absorption, can promote growth and development. After 20 kg, the childcare period can be released.
