Formula of nutrient for pigs as well as preparation method and application of formula

The invention discloses a formula of a nutrient for pigs as well as a preparation method and application of the nutrient, and belongs to the technical field of pig breeding. The formula of the nutrient for the pigs comprises the following components in parts by weight: 0.1 to 10 parts of VA, 0.1 to 10 parts of VD, 0.1 to 10 parts of VE, 10 to 70 parts of hexanoic acid, 10 to 70 parts of caprylic acid, 10 to 70 parts of capric acid and 20 to 70 parts of soybean lecithin. The nutrient formula enters animal intestinal tracts in a nano form, is directly absorbed by organisms to enter blood, is more beneficial to animal absorption, avoids a'short plate effect ', can also serve as a carrier of fat-soluble VA, VD and VE, accelerates absorption and utilization of vitamins, improves the utilization rate of feed, improves production performance and increases culture benefits. According to the nutrient formula, animal organisms can be adjusted to the optimal state, the meat quality is improved, meanwhile, sows are helpe
