Abstract
Chimeric somatostatin-based polypeptides, polynucleotides used to encode the polypeptides, the methods for isolating and producing the polypeptides and the uses thereof are provided. In addition, low cost adjuvants for enhanced immunogenic response are provided. Vaccinations that include both chimeric somatostatin-based polypeptides and novel adjuvants are included, useful in facilitating farm animal productivity.
Claims18
A method for increasing milk production in dairy cows comprising:
- vaccinating a dairy cow with one or more doses of an immunogenic composition comprising:
- (a) a chimeric polypeptide having the immunogenicity of somatostatin comprising an amino acid sequence of somatostatin-14 linked to a substantially inactive and truncated chloramphenicol acetyl transferase polypeptide wherein the somatostatin-14 is linked to the inactive chloramphenicol acetyl transferase by a spacer, wherein the inactive chloramphenicol has at least histidine residue 193 replaced with an alanine or glycine;
- and
- (b) a pharmaceutically suitable adjuvant in an amount effective to elicit an immune response;
- and
- allowing for at least ten days during which a dairy cow's milk production will increase as compared to the same cow's milk production in the absence of the vaccination.

A method for increasing lean meat production in a farm animal comprising;
- vaccinating the farm animal with one or more doses of an immunogenic composition comprising:
- (a) a chimeric polypeptide having the immunogenicity of somatostatin comprising an amino acid sequence of somatostatin-14 linked to a substantially inactive and truncated chloramphenicol acetyl transferase polypeptide wherein the somatostatin-14 is linked to the inactive chloramphenicol acetyl transferase by a spacer, wherein the inactive chloramphenicol has at least histidine residue 193 replaced with an alanine or glycine;
- and
- (b) a pharmaceutically suitable adjuvant in an amount effective to elicit an immune response;
- and
- allowing for several weeks during which the farm animal lean meat production will increase relative to lean meat production in a similar farm animal in the absence of the vaccination.
