Animal resistance to outside or to environmental stress may come from several sources. Resistance may result from an administered protector, either external or internal as with vaccinations, or the resistance may be due to some internally controlled body mechanism, as with natural immunity. If the resistance results from the latter, we refer to it as inherent or genetic resistance. At the South Dakota Experiment Station, we have initiated studies with both kinds of resistance. The progress with genetic resistance is the topic for discussion in this report.
