Foram feitos testes serológicoa para trinta e tres especificidades antigenicas, referentes a nove s1stemas de grupos sangdlneos (A, B, C, F, J, L, M, S e Z) e testes eletroforeticos em gel de amido, para quatro sistemas de polimorfismos bioquimicos (albumlna, anldrase carbonica, hemogloblna e transferrlna). A amostra consistiu de 922 animais, sendo 476 do grupo de lelte e 446 do grupo de corte, além de 358 descendentes lncluídos na anàlise de determlnaçao dos fenogrupos do sistema B. ...

Serological tests for 33 specificities of 9 blood group aystems (A, B, C, F, J, L, S, K and Z) and starch gel electrophoresis for albumin, carbonic anhydraae, hemoglobin and transferrin systems were done. A total of 922 animals were analysed, and of those 476 were classified as dairy cattle and 446 as beef cattle. In addition to that, 358 offsprings were typed for the purpose of phenogroup determination in the B system. ...
