The invention discloses application of 1, 4-dihydroxy-2-
naphthoic acid in improvement of animal growth performance and intestinal health, and belongs to the technical field of feed additives. According to the invention, the 1, 4-dihydroxy-2-
naphthoic acid is added into the basic feed, and tests prove that after the 1, 4-dihydroxy-2-
naphthoic acid is added, the average daily
gain and the average daily feed intake of broilers and piglets can be improved, and the
feed conversion ratio is reduced; the piglet
diarrhea can be improved, the development of the
stomach and the
small intestine of the piglet can be promoted, the morphological structure of the
jejunum of the piglet can be improved, the development of the intestinal tract can be promoted, the activity of stem cells of the intestinal tract of the piglet can be regulated, and then the development of the
gastrointestinal tract is promoted. Therefore, by adding the 1, 4-dihydroxy-2-naphthoic acid into the feed, the growth performance and the intestinal health of animals can be improved, the development of gastrointestinal tracts is promoted, the activity of the intestinal stem cells is regulated and controlled, and a new strategy is provided for improving the growth performance and the intestinal health of the animals.
