Forty six animals of the Gir breed, registered at the Brazilian Association of Zebu Breeders, coming from five farms located in Minas Gerais State, were used to analyze the efficiency of the microsatellites BM2113, ILSTS005, ILSTS008, ETH131 and RM88 in parentage tests. The loci BM2113, ILSTS005, ETH131 and RM88 showed to be efficient, presenting values of PE2 (exclusion probability when both parents are genotiped) between 0.62 and 0.69 and PIC2 (polymorphic information contents when both parents are genotiped) between 0.78 and 0.83. The same was not observed for the locus ILSTS008 that showed low values of PE2 (0.24) and PIC2 (0.41)
