Abstract

To assess the implications of parentage assignation on herdsgenetic improvement nine microsatellite markers were used in order to structure the genealogy of a multisired Braford herd. All progeny (100%) had satisfactory paternity assignment, conversely the maternity verification analysis showed assignation errors up to 90%. Our results support the use of molecular tools to verify the pedigree structure in those herds with management systems that limit the proper registration of progeny at calving.
