How is the feed-grade bile acid produced by Longchang Animal Protection Company?

Longchang bile acid is produced by saponification, decoloration, acidification, deacidification and crystallization with bile paste from which bilirubin has been extracted as raw material. The extraction process has obtained national patent. It is necessary to strictly control the temperature, time, dosage of alkali liquor, acid liquor and other materials in the extraction process, so that the bile acid produced in this way removes impurities such as fat, protein, pigment, pathogenic bacteria and so on, and is a non-toxic and residue-free additive.
