Sire-breed rotations are defined as the changing of sire breeds ignoring the sire-breed pedigree of dams from overlapping generations. The limiting theoretical proportion of maximum potential heterozygosity maintained at equilibrium when there is no culling of dams was found to be equal to that of a composite population with the same breed composition. Heterozygosity was simulated with a deterministic model that assumed 20% of reproducing females in each age group were culled each mating period… CONTINUE READING
