Fecal Egg Counts Remain High

On September 3, fecal egg counts ranged from 25 to 7825 and averaged 1971 + 1850 epg.  While the standard deviation was not as large as the mean, it was still quite large, indicating a wide variation in fecal egg counts. The median fecal egg count was lower at 1250 epg.

Samples could not be obtained from four goats. On September 3, nine goats were dewormed (with Prohibit® @ 3 ml/50 lbs.) based on FAMACHA© scores, the Five Point Check©, and other factors, including weight gain/loss and previous fecal egg counts.

As of day-56, approximately 25 percent of the bucks were meeting the GOLD standards for parasite resistance. The Gold standard requires an average fecal egg count below 500 epg and a high egg count that does not exceed 1000 epg. Several consignors have more than one buck that is still meeting the standards:  Dennison (2), Loyd (2), Majancsik (3), Nelson (3), Peters (2), and Weber (3).

As of day-45, #584, consigned by John Weber (IL), is the most parasite resistant buck in the test. He is also one of the top gainers (at 0.316), thus one of the current front-runners for top buck in the test.  Waldo Nelson has several of the top bucks in the test, considering both rate-of-gain and parasite resistance.

As of September 13, there are 18 days remaining in the test. Data, including fecal egg counts, will be determined two more times. The bucks will be scanned and evaluated for structural correctness and reproductive soundness (teats, testicles) before the test ends.

The top 10 bucks will be chosen primarily on the basis of growth rate (ADG), parasite resistance (fecal egg counts), and parasite resilience (FAMACHA© scores and anthelmintic treatments).
