coancestry and genetic gain would be change if a triplet concept would be
implemented.
Optimal genetic contribution theory in combination with minimum coancestry mating
with and without gene import from a related population has been proven to be an
adequate concept to manage genetic variability in a herdbook pig population under
practical conditions.
