100 percent barber pole worm

A pooled fecal sample was collected from the goats on July 7.  The sample was random, with feces being obtained from approximately every third goat worked.

The sample was sent via overnite mail to Dr. Ray Kaplan's lab at the University of Georgia, College of Veterinary Medicine, Department of Infectious Diseases.

After determining the fecal egg count of the pooled sample, the eggs were allowed to hatch.  The specific types of parasites in the sample were differentiated by examining and measuring the resulting larvae.

Caught with a mouthful

The fecal egg count for the pooled sample collected on July 7 was 450 epg, compared to 350 epg from the pooled sample collected on June 3-4 when the goats arrived to the test site.

One hundred percent of the strongyle-type (roundworm) eggs in the July 7th sample were determined to be barber pole worm (Haemonchus contortus), compared to 81 percent from the pooled sample collected on June 3-4.  Trichostrongylus was the other species found in the first pooled sample.

"Traces" of coccidia (Eimeria spp.) were also observed.  In the first pooled sample, a "moderate" (3+) amount of coccidia oocytes was observed.  Clinical coccidiosis was suspected in a few of the goats during the first half of the test.

It is difficult to completely prevent coccidiosis, as control and prevention depend upon adequate consumption of the drug or coccidiostat in the water or mineral. Next year, we plan to give each goat an individual treatment for coccidia upon arrival to the test site.
