Feed nutrition formula capable of improving reproductive performance of high-slope black pigs

The invention discloses a feed nutrition formula capable of improving reproductive performance of high-slope black pigs. The feed nutrition formula for the gestation period of the high-slope black pigs comprises the following components in parts by weight: 47-55 parts of corn, 8-16 parts of soybean meal, 9-17 parts of rice bran, 19-27 parts of chicory and 0.5-1.5 parts of calcium hydrogen phosphate. The nutritional formula of the feed for the high-slope black pigs in the lactation period comprises 49-57 parts of corn, 21-29 parts of soybean meal, 6-14 parts of rice bran, 6-14 parts of chicory, 0.75-1.75 parts of mountain flour and 0.25-1.25 parts of calcium hydrogen phosphate. The feed nutrition formula combination suitable for breeding sows from high-slope black pigs is formulated by combining the breeding condition of the high-slope region of Guiyang city, local farmers have abundant land for planting pasture and replacing part of concentrated feed with locally planted chicory, and the combination can reduc
