87 percent Haemonchus

The pooled fecal sample collected on July 3rd contained 87 percent Haemonchus contortus (barber pole worm), 7 percent Trichostrongyles/Teladorsagia and 6 percent other species (Oesophagostomum and Ostertagia).

The fecal egg count of the pooled fecal sample was 1750 epg. This was very similar to the average of individual fecal egg counts on July 3, which was 1680 ± 1607 epg.

The first pooled fecal sample was collected on May 31. It contained only 49 percent Haemonchus. In past years, Haemonchus has always comprised the majority of the worm load, usually nearing 100 percent as the test progresses. The first pooled sample is usually the most diverse.

Another pooled sample was collected from the goats on August 14. It was submitted to Dr. Dahlia O'Brien's lab at Virginia State University for larvae ID. All fecal testing for the test is done by Dr. Dahlia O'Brien's lab.
