Isolated peptide construction from 104-113 of the growth hormone GH, animal feeds comprising this for growth and lactation

摘要

Isolated peptide construction comprising all or part of the sequence GSDRVYEKL extending from position 104-113 of the growth hormone GH, or of a homologous sequence of the sequence exhibiting an immunological cross-reaction, the peptide construction being covalently linked to a transporter peptide and/or an adjuvant, and having a potentiating effect on the biological activity of the growth hormone. Further claimed is the recombinant nucleic acid incorporating the above isolated peptide, and use of the composition for feedstuff additives to stimulate the growth and lactation of the vertebrates which ingest them.
