The present invention provides a use of an acylated derivative of an amino acid in preparing animal feed additive. The acylated derivative of the amino acid or a racemate, stereoisomer, a geometric isomer, a tautomer, a solvate, and a feed-acceptable salt thereof of the present invention has a structure represented by formula (I).
The acylated derivative of the amino acid or the racemate, the stereoisomer, the geometric isomer, the tautomer, the solvate, and the feed-acceptable salt thereof provided in the present invention may be used as an animal feed additive, and has a good effect of improving production performance of animals.

Xylaria arbuscula was collected from a "Cypress" tree, Cupressus lusitanica. The whole cells of this endophytic fungus were used in screening for microbial bioreduction of aryl acids. Different p-substituted benzoic acids were evaluated. However, only p-bromobenzoic acid, p-chlorobenzoic acid and p-nitrobenzoic acid were converted to their corresponding alcohols. Aryl acid metabolism of X. arbuscula included GABA incorporation and glycosylation when the substrates were p-bromobenzoic and p-chlorobenzoic acids were also observed. The substrates p-hydroxybenzoic and p-aminobenzoic acids were not transformed. These results could suggest that electron-withdrawing groups at para orientation activate the substrate for reduction.
