Optimum contribution selection for conserved populations with historic migration.

ABSTRACT:

Background

In recent decades, local varieties of domesticated animal species have been frequently crossed with economically superior breeds which has resulted in considerable genetic contributions from migrants. Optimum contribution selection by maximizing gene diversity while constraining breeding values of the offspring or vice versa could eventually lead to the extinction of local breeds with historic migration because maximization of gene diversity or breeding values would be achieved by maximization of migrant contributions. Therefore, other objective functions are needed for these breeds.

Results

Different objective functions and side constraints were compared with respect to their ability to reduce migrant contributions, to increase the genome equivalents originating
