A rapid method to determine free Try and total Try in serum with HPLC is described in this paper.

Sixty crossbred pigs weaned at 2 8days of age were randomly divided into four groups and fed the diet had a similar DAA or total amino acids(TAA) .

METHODS The experiment was designed with orthogonal test method,and the yield of total amino acid and guaiacol were used as the testing index.

Objective: To study the method of determination of total amino acid in seselopsis.
