摘要：
The invention relates to the use ofDL-methionyl-DL-methionine and salts thereof as a feed additivein feed mixtures for animals held in aquacultures, and amethod for producing DL-methionyl-DL-methionine (I)having the formula (I) by converting a urea derivative of thegeneral formula (II) to DL-methionyl-DL-methionine,wherein the groups R1 and R2 in the urea derivatives IIa, IIb,IIc, IId, IIe, IIf, and IIg are defined as follows: IIa: R1 =COOH, R2 = NHCONH2 IIb: R1 = CONH2, R2 = NHCON-H2 IIc: R1 = CONH2, R2 = NH2 IId: R1 -R2 =-CONH-CONH-IIe: R1=CN,R2 =OH IIf:R1=CN,R2=NH2 IIg:R1= =O, R2 = H.
