MICROSATELLITES ANALISIS FOR THE STUDY OF BIODIVERSITY AND TRACEABILITY OF THE PIG
Keywords:
genetic diversity, microsatellitesAbstract
Traceability of animals and animal products has a priority for governments of the
European countries. The great development reached by the molecular genetic in last
decades, has determined a high knowledge of the genome of the different species.
The Deoxyribonucleic Acid (DNA) of each animal is different (with the exceptions of
monozygotic twins and clones). Since the genome of each animal contains
approximately three billion DNA units, the range for variation among the DNA
sequences of animals is enormous, consequently DNA markers analysis allows
assuring a traceability of 100% in the meat industry. A methodology using 17 ISAG
(International Society for Animal Genetics) DNA microsatellite markers is proposed
for meat traceability. Principal methods used to reveal DNA polymorphism are
described as their applicability in species identification and meat traceability. The
objective it was analysis the DNA profile of pig with 10 microsatellite markers and
results of meat identity control.
