Resumen:
Livestock robbery is a frequent illegality in Argentina that cause lost of several
millions a years and is a serious risk to the public and animals health. To prevent
and solve this type of illegal action, we designed and implemented the official plan
Prevention and Resolution of Livestock Stealing Cases in Buenos Aires Province.
This project included different stages: (i) solving court cases using genetic
information; (ii) genetic characterization of the bovine and equine population bred in
the Pampa region; (iii) creation of a biological samples reservoir that could be used as
reference samples in future robbery; (iv) A database with DNA sample information
was created, and a sample management and analysis system is under development.
Biological samples (N=227) from 84 court caseworks of livestock illegal hunting (78
cases) or robbery (4 cases) were analyzed. The remaining cases (N=2) corresponded
with specific specie identification of the evidence samples. Eleven STRs were used
for individual identification, while the mitochondrial cytochrome b was genotyped
for specie identification. Match probabilities between evidence and reference samples
were calculated from different cattle breed databases from the Buenos Aires
Province. Because of the relatively high grade of putrefaction of the forensic
biological materials, we can not obtained good quality DNA in 16 caseworks. Within
the remaining samples, the number of successfully genotyping locus by sample
varied from 4 to 11. In 16 caseworks, the genotypes of evidence and reference
did not matched, while in 50 caseworks, the evidence profile match with the
reference genotypes. In those cases, the likelihood ratio ranged from 68,000 to
1.2 x 1013. In conclusion, herein we described a plan where DNA profiling was
used as evidence for the detection of cattle and equine illegal hunting or
robbery, supporting the prosecutor accusation in court.
