The eggs in the pooled sample were allowed to hatch, so that the species of worm could be identified from the larvae. It is not possible to differentiate the eggs of most strongyle-type worms.

The pooled sample contained 70 percent Haemonchus contortus, better known as the barber pole worm. Eighteen (18) percent of the larvae were Trichostrongyles or Teladorsagia, better known as "bankrupt worms." The other 12 percent were classified as other, including Oesophagostomum (nodule worm).
The fecal egg count of the pooled sample was 2675 epg. This is considerably higher than the average of the individual samples collected on June 23-24, which was 1207 ± 3201 epg, with a median of only 100 epg.
The next pooled sample will be collected on August 3. It will be submitted to the University of Georgia for a DrenchRite® test. In addition to fecal egg count and larvae ID, the DrenchRite® test determines resistance to all anthelmintics (dewormers) simultaneously.
