1. SNP discovery and characterisation in White Rhino (Ceratotherium simum) with application to parentage assignment
Abstract The white rhino is one of the great success stories of modern wildlife conservation, growing from as few as 50-100 animals in the 1880s, to approximately 20,000 white rhinoceros remaining today. However, illegal trade in conservational rhinoceros horns is adding constant pressure on remaining populations. Captive management of ex situ populations of

2. Validation of a microsatellite panel for parentage testing of locally adapted and commercial goats in Brazil
Brazilian goats are generally kept in small herds and extensive rearing systems, mainly in the northeastern region of the country. Despite production improvement in recent years, the lack of pedigree control has affected genetic progress. This study aimed to validate a panel of 16 microsatellites for parentage testing in locally adapted and commercial goats

3. Assessing paternity in japanese quails (Coturnix japonica) using microsatellite markers - inferences for its mating system and reproductive success
Microsatellite markers were analyzed in Japanese quails, Coturnix japonica, using different methodologies (PAGE and automated genotyping), in order to evaluate their use in paternity testing. Ten animal triplets composed by a female and two males were used to mate and generate an offspring. Paternity was determined in five-day-old embryos, and the data gener

4. Parentage test in broad-snouted caimans (Caiman latirostris, Crocodylidae) using microsatellite DNA
In this study, microsatellite markers, developed for Alligator mississipiensis and Caiman latirostris, were used to assess parentage among individuals from the captive colony of Caiman latirostris at the University of São Paulo, in Piracicaba, São Paulo, Brazil. Many of the females in the colony were full siblings, which made maternal identification diffic

5. DNA testing for parentage verification in a conservation nucleus of Pantaneiro horse
We investigated the genealogy of the in situ conservation nucleus of the Pantaneiro horse using DNA microsatellites by evaluating 101 horses, the group consisting of 71 adult horses (3 stallions, 40 male and 31 mares) and 27 foals (14 colts and 13 fillies). Genomic DNA was extracted from hair roots and genotyped using 12 microsatellite markers (AHT4, AHT5, A

6. Variabilidade e desempenho forense de microssatélites utilizados na verificação de parentesco do plantel brasileiro de cavalo puro sangue inglês (PSI)
Thoroughbred horses (TB) is a breed derived from a considerably narrow genetic base involving a few founder stallions, displaying today a reduced allelic diversity when compared to other horse breeds. TB animals, however, demand a very high rigor in the genealogical control in view of its international reputation and ample worldwide trading in which Brazil p

7. Microsatellites in Portuguese autochthonous horse breeds: usefulness for parentage testing
The use of DNA technology for parentage testing is increasing every day. Most laboratories have improved their exclusion probabilities (PE) by the addition of DNA microsatellite loci to standard blood-typing results. The efficacy of each locus depends on the number of alleles detected and their frequencies in the breeds tested. Here we analyzed the usefulnes

8. Parentage testing and effect of misidentification on the estimation of breeding value in Gir cattle
A correct relationship among sires is essential for an efficient breeding program. Microsatellite markers were used in progeny tests, to assess the paternity of seventy-four probable offspring of nine Gir dairy sires. A 36% misidentification rate was observed; however, these errors had minimal effects on the ranking of the nine bulls with regard to their gen

9. Parentage verification and its effects on breeding in Gir cattle. / Investigação de paternidade e seus efeitos no melhoramento de bovinos da raça Gir leiteiro.
Com o aumento da produtividade na área agropecuária, houve um aumento na busca por sistemas de produção mais eficientes e competitivos. Neste contexto, o melhoramento genético animal tem proporcionado avanços na obtenção de produtos de origem animal, principalmente na seleção de touros. A superioridade genética de touros para produção de leite n
