As proteínas do plasma seminal de 14 reprodutores (7 Bos taurus taurus e 7 Bos taurus indicus), foram analisadas por eletroforese bidimensional, em géis de poliacrilamida a 8%, corados por Comassie Blue. Três bandas protéicas, presentes em 100% das amostras de plasma seminal, foram quantificadas de acordo com a densidade óptica exibida: 195 kDa, pI 6,5-7,5 ; 66 kDa, pI 5,4 e 55 kDa, pI 4,5. As amostras de plasma seminal provenientes de taurinos apresentaram densidades ópticas significativamente superiores (p < 0,05) às dos zebuínos na bandaTwo dimensional polyacrylamide gel electrophoresis was performed in seminal plasma of seven Bos taurus taurus and seven Bos taurus indicus bulls with high semen freezability, from an artificial insemination center. In a 8% polyacrylamide gels, three bands of 195, 66 and 55 kDa, present in 100% of the samples in both sub-species, were analyzed by their optical densities. In Bos taurus samples, the opticals densities of 55 kDa band, imunoidentified as osteopontin were superior (p < 0.05) than Bos indicus samples. The 66 kDa band was imunoidentified as albumin. In the Bos taurus samples, the bands did not show any variation among the bull samples, but in the Bos indicus, the albumin optical densities showed significant variation among samples
