Microsatellite based ovine parentage testing to identify the source responsible for the killing of an endangered species.

In this study, we present an animal forensic genetics case in which we applied ovine microsatellite based parentage testing to the resolution of an act against protected wildlife. The aim was to identify the origin of the animal responsible for the death of an Egyptian vulture (Neophron percnopterus) that had been poisoned through consumption of a Latxa Blond Face breed lamb. Thus, we carried out a 22 microsatellite based parentage test in order to identify the parents of the lamb in the flock which grazes in the same place where the vulture's remains were found. Multiple parentage analysis revealed two possible parents, one ewe and one ram, with a combined paternity/maternity index (PI) higher than 9.09E9 and a likelihood (W) value of 99.9999%, assuming 50% probability a priori. This result confirmed the flock of origin of the poisoned lamb and shows that the microsatellite panel described herein is a potentially useful tool for the resolution of animal forensic cases.
