Achieving high yields for gilts and prolonging the useful life of sows are closely related to nutrition regulation. To achieve the prolonged use of gilts and the high yield of multiple births, nutrition control measures must be taken in stages. 30-85 kg phase of nutrition regulation. When a gilt weighs 30 kg, formulated feed per kilogram should contain 13 megajoules of digestive energy, 16% of crude protein, 0.8% of lysine, 0.75% of calcium, 0.65% of phosphorus, free intake, and no control of feed. The gilt grows as soon as possible. Starting from a weight of 45 kg, the calcium and phosphorus levels in the diet increased by 0.1 percentage points. When the gilt was 5 months old and weighed around 85 kg, it began to restrict feeding. Similarly, the above-mentioned diet was fed, and the daily feed intake was controlled at 2.3-2.8 kg depending on the body condition. 110 kg to the stage of nutrition control. When the gilt is 8 months old and the body weight is 110 kg, the initial allocation is more appropriate. The first estrus period does not require breeding. At this time, the sow's ovarian function is not yet complete. Feeding aphrodisiac began two weeks before breeding and the amount of feeding increased by 40-50% to reach a daily feed of 3.8-4 kilograms of compound feed. Supplementary aphrodisiac can increase ovulation, and the number of litters per litter can increase by 2. Immediately after the end of breeding, the amount of feed was reduced to the level before the aphrodisiac, which was about 2.2 kg per day. The diet contained 12.1 MJ of digestive energy per kilogram, 13% of crude protein, 0.6% of lysine, and 0.75% of calcium. Phosphorus 0.65%. From the 84th day of pregnancy, dietary nutrient levels can be increased to 12.5-13 MJ per kilogram of digestible energy, including 14% crude protein, 0.75% lysine, 0.8% calcium, 0.65% phosphorus, and 3.25-day feeding volume. 3.5 kg. Two to three days before delivery, the daily feeding amount is reduced to about 1.8 kg so as not to cause dystocia. Postpartum and lactation nutrition regulation. After 5-7 days of sow farrowing, the amount of feeding should be gradually increased to the maximum. One is based on a diet of 1.5 kilograms, which increases 0.5 kilograms of feed per nurtured piglet, and 6.5 kilograms per day if nurturing 10 piglets. If the sow feed intake is low, consider adding 2-4% of fat to the diet and increasing the protein content of the diet accordingly to ensure that the sow has sufficient lactation. During this period, each kilogram of diet should contain 13-13.8 MJ of digestive energy, containing 14-16% of crude protein, 0.7-0.75% of lysine, 0.84% ​​of calcium, and 0.7% of phosphorus.
