Fecal Egg Counts Still Low

For the samples collected on June 19, fecal egg counts ranged from 0 to 6475 epg and averaged 464 ± 1105 epg. The median egg count was 66 epg, similar to the median on May 30.

Only 15 goats (19%) had fecal egg counts above 500 epg, the test's Gold Standard of Performance. To qualify as a Gold-performer, a buck's average fecal egg count must be below 500 epg. His high egg count cannot be above 1000 epg. Only 8 bucks (10%) had fecal egg counts above 1000 epg.

#421 (Burke) had a negative fecal test (0 epg)

A Silver-perfoming buck must have an average fecal egg count below 750 epg and cannot have a fecal egg count above 1500 epg. A Bronze-performing buck must have an average fecal egg count below 1000 epg and cannot have an egg count above 2000 epg. Six bucks (8%) had fecal egg counts above 2000 epg, which usually disqualifies them from the sale.

2,000 epg per gram is considered to be of clinical significance for the barber pole worm, which is a very prolific egg layer.

Twenty-four bucks (31%) had negative fecal tests: 0 epg, including all the bucks in the consignments of Sam Burke (DE), Gery Glover (MD), and Mike Renick (WV). Coccidia oocytes were noted in only one fecal sample. 

#465 (Renick) had no worm eggs in his feces.

This is the first fecal data that will factor into the test results. The next individual fecal samples will be collected on July 3. A pooled sample will also be collected for coproculture (larvae ID).
