Peptide, immunogenic composition and vaccine or medical preparation, a method to immunize animals against the hormone LHRH, and analogs of the LHRH tandem repeat peptide and their use as vaccine

摘要

A peptide that comprises a modified tandem GnRH decapeptide sequence which allows for a testosterone level that is essentially nondetectable after vaccination with the peptide in a suitable dosage and/or allows for an immunogenic response that allows for the effective discrimination between GnRH-I and GnRH-II and a method for the immunocastration of pigs.
