The Silver standard is an average FEC below 750 epg and the high FEC below 1500 epg. One buck met this standard: 699 (Yutzy, Ohio). The Bronze standard is an average FEC below 1000 epg and the high FEC below 2000 epg. Three more bucks met this standard: 687 (Weber, IL), 648 (Murphy, NJ), and 616 (Davis, MO).
Six of the most resistant bucks in the test were top 10 performers. The other four had other disqualifying data, such as low rate-of-gain or need for anthelmintic treatment. Only bucks with four samples or more were considered for top 10 ranking in parasite resistance.
Waldo Nelson from Maryland had two of the ten most resistant bucks in the test. Waldo has had resistant bucks in other tests.

Being one of the most resistant bucks (especially top 5) is especially noteworthy this year, as the highest ever fecal egg counts were recorded. Egg counts may have gone even higher if a sample had been collected on September 29 (though all the goats were given 1 g bolus of COWPs, which may have kept egg counts from going even higher).
