High fecal egg counts

For the fecal samples collected on September 15, fecal egg counts ranged from 150 to 14,325 epg and averaged 3,050 epg, as compared to 1,437 on September 1.

Seventy-three percent (n=59) of the goats had fecal egg counts above 1,000 epg.  Forty-nine percent (n=39) had fecal egg counts above 2,000 epg. As a precaution (due to increasing egg counts), goats with FAMACHA© scores of 3 were dewormed on September 15 with levamisole (3 ml/50 lbs.).

After being picked up from the test site, producers should continue to monitor the goats for internal parasitism. The increased rainfall during the past six weeks has greatly increased the goats' exposure to infective worm larvae.

Pooled fecal sample
For the pooled fecal sample collected on September 1, the fecal egg count was determined to be 1,008 epg as compared to 400 epg for the pooled sample collected on August 4. Pooled samples are collected randomly from every third goat.

Ninety-four percent of the strongyle eggs were determined to be Haemonchus contortus (barber pole worm).  Two percent were Trichostrongylus and four percent were Oseophagostumum.

Special thanks to Dr. Dahlia O'Brien and her graduate students at Delaware State University for getting the last set of fecals analyzed quickly, so they could be included in the final test results.
