Feeding method capable of improving performance of Danseries sows

The invention discloses a feeding method capable of improving the performance of Dan-series sows, which is characterized in that feed supply is accurately carried out according to different stages of the growth cycle of the Dan-series sows, specifically, the number of days from hybridization to pregnancy to delivery, lactation, weaning and hybridization of the Dan-series sows is divided into eight stages, and the Dan-series sows are fed into the eight stages. From mating to 20 days of pregnancy, from 20 days to 85 days of pregnancy, from 85 days to 100 days of pregnancy, from 100 days to 114 days of pregnancy, from 114 days to 116 days of pregnancy, one day after birth, 2 days to 3 days after birth, and from 4 days to weaning; feeding according to a feeding amount curve from hybridization to 114 days of pregnancy, wherein the whole feeding amount curve is in a low-medium-high curve shape; a high feeding amount is maintained one day after farrowing. According to the method, the scientificity of feeding the pre
