Egg counts go back up

For the fecal samples collected on August 18, fecal egg counts (FECs) ranged from 0 to 5,100 and averaged 887 epg, compared to 338 epg on August 4.

Egg counts for some of the goats went up.  No goat experienced a significant reduction in fecal egg count, as compared to two weeks ago.

Twenty-two goats had fecal egg counts above 1,000 epg.  These goats, which represent 28 percent of the goats in the pasture test, accounted for 69 percent of the total egg output.  The twenty percent of the goats (n=16) with the highest egg counts accounted for 60 percent of the total egg output.

Ten goats had fecal egg counts above 2,000 epg.  These goats, which represent 13 percent of the goats in the pasture test, accounted for 48 percent of the total egg output.

Thirty-eight percent (n=30) of the bucks are still meeting the Gold standard of performance for parasite resistance, failing to have an egg count above 500 epg.  All of the bucks consigned by Jeanne Dietz-Band (MD, n=3) and Mike and Lorie Renick (WV, n=5) are meeting the gold standard for fecal egg counts.

All of the Renick's bucks are low egg shedders

For the goats in the pen, fecal egg counts ranged from 0 to 771 and averaged 313 epg, as compared to 140 on August 4.
