“…Recently, Baldo et al (2010) showed that in beef traceability ∼25% more microsatellite markers were needed to identify consanguineous animals vs. unrelated animals. In contrast, our results show that, in this same context, the number of SNPs needed to provide the same Q in consanguineous samples and in the Illumina reference samples would be similar.…”

Comparison of the effectiveness of microsatellites and SNP panels for genetic identification, traceability and assessment of parentage in an inbred Angus herd

During the last decade, microsatellites (short tandem repeats or STRs) have been successfully used for animal genetic identification, traceability and paternity, although in recent year single nucleotide polymorphisms (SNPs) have been increasingly used for this purpose. An efficient SNP identification system requires a marker set with enough power to identify individuals and their parents. Genetic diagnostics generally include the analysis of related animals. In this work, the degree of information provided by SNPs for a consanguineous herd of cattle was compared with that provided by STRs. Thirty-six closely related Angus cattle were genotyped for 18 STRs and 116 SNPs. Cumulative SNPs exclusion power values (Q) for paternity and sample matching probability (MP) yielded values greater than 0.9998 and 4.32E−42, respectively. Generally 2–3 SNPs per STR were needed to obtain an equivalent Q value. The MP showed that 24 SNPs were equivalent to the ISAG (International Society for Animal Genetics) minimal recommended set of 12 STRs (MP ∼ 10−11). These results provide valuable genetic data that support the consensus SNP panel for bovine genetic identification developed by the Parentage Recording Working Group of ICAR (International Committee for Animal Recording).

“…25 SNPs are equivalent to the 12 dinucleotide STRs of the minimal set recommended by ISAG (MP c . 10 −11 ; e.g., ). Our average call rate was slightly higher than that of 25‐SNP limit value which was proposed by different authors to get enough discrimination power for bovine genetic identification which is the case of cattle rustling.…”

“…Previous studies showed that for match comparison purposes (e.g., traceability and forensic analysis), between two and three SNPs per STR were needed to obtain an equivalent statistical power (exclusion power, 15,16). Match probability values showed that c. 25 SNPs are equivalent to the 12 dinucleotide STRs of the minimal set recommended by ISAG (MP c. 10 À11 ; e.g., 15,16,43).…”

“…During the last decades, animal DNA evidence has been successfully used in litigation (11)(12)(13). DNA technology provides reliability and accuracy in performing parentage testing and in individual identification (e.g., 6,12,[14][15][16][17][18]. Animal DNA profiles have been used as probative evidence to successfully resolve real legal cases, such as cattle rustling, horse doping, wildlife trafficking, and animal attack cases (2)(3)(4)8,(19)(20)(21)(22)(23)(24).…”

Short tandem repeats (STR)s have been the eligible markers for forensic animal genetics, despite single-nucleotide polymorphisms (SNP)s became acceptable. The technology, the type, and amount of markers could limit the investigation in degraded forensic samples. The performance of a 32-SNP panel genotyped through OpenArrays(TM) (real-time PCR based) was evaluated to resolve cattle-specific forensic cases. DNA from different biological sources was used, including samples from an alleged instance of cattle rustling. SNPs and STRs performance and repeatability were compared. SNP call rate was variable among sample type (average = 80.18%), while forensic samples showed the lowest value (70.94%). The repeatability obtained (98.7%) supports the used technology. SNPs had better call rates than STRs in 12 of 20 casework samples, while forensic index values were similar for both panels. In conclusion, the 32-SNPs used are as informative as the standard bovine STR battery and hence are suitable to resolve cattle rustling investigations.
