However, in recent years, SNPs have gained traction. This study aimed to evaluate the performance of a SNP panel for genotyping cattle breeds in forensic investigations. Samples from pure and mixed breeds and from forensic cases were genotyped using SNPs and STRs. SNP results showed a performance of 80.18% of call rate. Comparison between forensic and reference samples showed that the obtained average call rate value for casework was lower than that obtained for reference samples (70.94%). The SNPs exhibited a high percentage of concordant calls between replicates (98.7%). Significant differences in SNP genotyping performance were found among the different biological sources. When the call rates for SNPs and STRs were compared, SNP performed better than STR in 12 out of 20 casework samples. Results revealed that the 32 SNP panel is as informative as the standard bovine STR battery for cattle rustling investigations.
