| abstract |
The present invention describes compositions and methods for modulating the activity of the somatotropin releasing inhibitory factor (SRIF), as well as improving reproductive performance and immunological function in vertebrates. The compositions containing such peptides related to SRIF factor or antibodies to these peptides can be administered to animals, in order to obtain a modulation of the activity of endogenous SRIF factor. These SRIF-related peptides can be linked to an excipient, such as ovalbumin, and administered in an AL (OH) 3 adjuvant, to increase the immunogenicity of SRIF-related peptides. |
