The pendulum for North America seems to swing from "there is enough diversity in our existing populations" to "there is not enough diversity and something big needs to be done about it". The conclusions seem to depend on the samples collected, the molecular markers used, the metrics used to analyze the marker distributions, and maybe even the intent of the study- as in some groups want to import material, others want to promote prior importations, and others are keen on locally "adapted" stocks or ones they have selected for.
One definite factor influencing mis-perceptions of inbreeding comes from the fact that from a genetic standpoint a individual mated queen (whether from an importation of a distinct selected or "adapted" lineage) is not the equivalent of one typical farm animal with one genome, but a combination of a dam and dozens of sires.
