ABSTRACT
Bovine serum transferrin types on 520 Holstein animals were used to supplement erythrocyte antigen data in evaluation of animal relationships. Within the group of animals studied, transferrin types significantly increased the effectiveness of determining animal relationships. Transferrin types appear to be most useful in cases of multiple births, and among groups of cattle with similar cellular antigen types.
