The feeding and management of sows during pregnancy is a key issue. It is necessary to strengthen the management from the following aspects according to the nutritional physiological characteristics of the sow during pregnancy and the rational preparation of daily doses in combination with actual conditions. First, the sow's diet must have a certain volume, and there must be a certain amount of green roughage, so that the sow eats and feels full, does not oppress the fetus, and more importantly, the green roughage is conducive to the development of the embryo. However, after 3 months of pregnancy, it is appropriate to limit the amount of green roughage, otherwise the compression of the fetus can cause miscarriage. Secondly, pregnant sows with better lyrical conditions should be kept in limit, and the amount of feed intake should be limited as much as possible in order to achieve weight control and save on feeding costs. Third, pregnant sows should be properly exercised in the middle and later stages, which will help improve physical fitness and fetal development, and stop exercising for one week before delivery. Fourth, do day-to-day management to prevent miscarriage: You must be gentle on pregnant sows, avoid panic attacks, nap, and feed that is not suitable for feeding mildew, spoilage, or deterioration. Fifth, to do deworming, parasites will lead to decreased appetite in pregnant sows, and then weight loss, and some sows even if the appetite does not fall will appear "not eat long" situation, in the first 15 days before litter must be carried out once Deworming can eliminate the effects of chronic wasting disease.
