Application of pharmaceutical by-products of Isatis indigotica
By processing Isatis root residue into solid residue and adding it to piglet feed, the intestinal flora and liver function can be regulated, thus addressing the insufficient application of Isatis root pharmaceutical by-products in piglet farming. This results in improved intestinal flora and liver function, enhancing piglet health and farming efficiency.

AI Technical Summary
In the existing technology, the application of Isatis root pharmaceutical by-products in regulating the intestinal flora and improving liver function in piglets has not been fully studied. Moreover, the related products are difficult to obtain and costly, which limits their promotion in breeding. At the same time, piglets often experience intestinal flora disorder and liver and kidney damage after weaning.
The residue of Isatis root is extracted by boiling in water, filtered and separated, then dried and pulverized to produce a solid residue substance with a water content of ≤12wt%. This substance is added to piglet feed to regulate intestinal flora and improve liver function. Specific components include L-arginine, guanine, L-phenylalanine, epigallocatechin, deoxydaunocarbazine, 3-indoleacetonitrile, indigo, and indirubin, which reduce the abundance of specific bacterial groups and serum indicators.
It effectively regulates the intestinal flora of piglets, reduces the abundance of specific bacteria, improves liver function and lipid metabolism, reduces weaning stress response, improves health status and breeding efficiency, reduces serum enzyme and bile acid levels, and increases serum protein content.
