Abstract


The paper presents a genetic characterization of cattle breeds in Romania based onbiochemical markers in the blood and the milk. The surveyed breeds are: RomanianBlack Spotted Cattle (BNR), Romanian Spotted Cattle (BR), Romanian Brown (B)and Romanian Steppe, and the markers identified are represented by some proteins,serum transferrin (Tf), serum albumins (Al), hemoglobin (Hb) respectively-from theblood and beta-lactoglobulin (βLg)-from the milk. In order to determine thegenotypes in the studied populations electrophoresis was used in three differentvariations, depending on the type of the protein, and the migration substrates usedwere starch and polyacrylamide. The identified genetic structures in the individualsfrom the surveyed breeds allowed their genetic characterization based on gene andgenotype frequencies, as well as using these data in establishing the identity andpaternity of the individuals in the surveyed breeds.
