Feedstuff capable of increasing sow production performance in large-scale pig farm and feeding method thereof

The invention relates to a feed which can improve the large-scale hogpen sow production performance, and a breeding method; the feed comprises the following components based on weight proportions: 35-45 portions of corn, 5-10 portions of wheat bran, 5-10 portions of soybean meal, 5-15 portions of miscellaneous meal, 15-20 portions of fermented protein, as well as 10-15 portions of functional combined fibers. Aiming at the nutritional needs of sows at different stages, the invention prepares rational daily diet and uses the rich feedstuff to prepare the daily diet, as well as makes use of the fermented products in the food industry and the functional combined fibers to greatly meet the nutrient type and quality needs of the sows to improve the intestinal health of the sows, reduce the constipation problem of sows during pregnancy and improve the survival rate of embryos and litter size. The invention makes full use of fermented protein, lysine and other special nutritional factors to balance the daily dietary amino acid so as to meet the needs on micro-nutrients of the sows and promote the development of the fetus.
