Zusammenfassung:	An animal growth promotant which comprises as an effective ingredient a peptide of the following formula I: X-A-B-Trp-C-Y wherein X is selected between hydrogen and t-butoxycarbonyl; A is selected from the group consisting of Leu, Ile, Phe, Ahx, Met, MetO and Phe(Cl), either of L- or D-configuration; B is selected from the group consisting of Pro, Ala, Gly, Val, Leu and Pip, either of L- or D-configuration; C is selected from the group consisting of Val, Leu, Met, MetO, Ile, Phe, Phe(Cl) and Ahx, either of L- or D-configuration; or A, B and C independently represent a chemical bond provided that at least one of them is an amino acid residue; Y is selected from the group consisting of OH, OMe, OEt, OBzl, NH2, NH-Et, NEt2 and the veterinarily acceptable salts thereof. A feed or veterinary composition containing it, and a method for promoting the growth of animals are also provided. New compounds according to formula I, wherein A is different from L-Leu or L-Phe or C is a chemical bond, as well as a method for preparing the same is disclosed.
