Teste de DNA para verificação de parentesco em cães: avaliação do método não automatizado com o auxílio do primer CMR S

To evaluate the precision of the DNA tests using the non-automatized technique for individual identification and parentage tests, 105 Rottweiler dogs were studied using the primer CMR S. The sample was composed of 39 animals belonging to 11 complete families and their progenies, and 66 non related individuals until the second generation, derived from kennels located in the states of Minas Gerais and São Paulo. The CMR S primer was used for the Polimerase Chain Reaction (PCR). The results showed the inefficiency of the technique, even when analyzed through the automated gel analysis system. Also showed the impossibility of its commercial use due to the fact of does not permit the storage of data for subsequent use.

Microssatélites BM2113, ILSTS005, ILSTS008, ETH131 e RM88 em testes de verificação de parentesco para bovinos da raça Gir / Microsatellites BM2113, ILSTS005, ILSTS008, ETH131 and RM88 for parentage tests in bovines of Gir breed

Foram utilizados 46 animais da raça Gir, registrados na Associação Brasileira de Criadores de Zebu, provenientes de cinco fazendas situadas no Estado de Minas Gerais, com o objetivo de avaliar a eficiência dos microssatélites BM2113, ILSTS005, ILSTS008, ETH131 e RM88 em testes de verificação de parentesco. Os locos BM2113, ILSTS005, ETH131 e RM88 mostraram-se eficientes, apresentando valores de PE2 (probabilidade de exclusão quando os dois progenitores são genotipados) entre 0,62 e 0,69 e PIC2 (conteúdo de informação polimórfica quando os dois progenitores são genotipados) entre 0,78 e 0,83. O mesmo não ocorreu para o loco ILSTS008, o qual apresentou baixos valores de PE2 (0,24) e PIC2 (0,41).(AU)

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).(AU)
