You will definitely get anti-BSA antibodies, and there is no easy way to
avoid this in the production of polyclonal antisera (although substractive
immunization is a possibility but better suited for mice and the
production of monoclonal antibodies). However, one useful strategy is to
immunize with the peptide conjugated to a carrier such as KLH, and then
assay the antiserum using the peptide to another carrier such as BSA.
This way, the antibodies raised against the carrier will not be detected
in the assay (for example, in an ELISA).
