Abstract

A correct relationship among sires is essential for an efficient
breeding program. Microsatellite markers were used in progeny tests, to
assess the paternity of seventy-four probable offspring of nine Gir
dairy sires. A 36% misidentification rate was observed; however, these
errors had minimal effects on the ranking of the nine bulls with regard
to their genetic values. The results suggest that paternity tests
should be performed in breeding programs, in order to prevent
inappropriate paternities from influencing the genetic value of bulls
in the future.
