1. Strengthen feeding. According to the body condition of pregnant sows, increase or decrease concentrate properly to prevent overweight or overweight. Pay attention to supplementary feed during pregnancy, especially to gradually increase the proportion of concentrate in the diet, prenatal one month, adjust the diet formula, add enough green succulent feed, supplement formula feed rich in protein, minerals and vitamins. For 3-5 days before delivery, the diet should be reduced by 10-20%; on the day of delivery. Do not feed concentrate, feed appropriate amount of bran soup with a small amount of salt.

2. Provide adequate drinking water. Sows in the lactation stage need a lot of water, and only by providing adequate clean drinking water can they have normal milk production.

3. Maintain good environmental conditions. The faeces should be cleaned at any time to keep the pig house clean, dry and well ventilated. In winter, we should pay attention to keep warm and prevent the attack of thief wind. In summer, we should pay attention to heat prevention, add heat prevention and cooling facilities to prevent sow heatstroke. Strong external stimulation is strictly prohibited to keep the pigsty quiet.

5. Protect sow breasts and nipples. The development of breast and mammary gland of sows has a lot to do with sucking of piglets, especially for first-born sows, all nipples must be used evenly, so as to avoid poor development of unused breasts and affect milk production. The fence should be flat, especially the birth bed, to remove protruding sharp objects to prevent cutting off the nipple.

6. Accurately grasp the age of first match. The first mating age of sows depends on the breed, and the first mating age varies with different breeds. The local sows are 6 ~ 8 months old, the body weight is 60 ~ 80 kg, and the exotic improved breed sows are 8 ~ 10 months old, with a weight of 90 ~ 100 kg. At the same time, the aged sows with low lactation were eliminated in time.
