Virginia Tech researchers evaluated the relationship between fecal egg count (FEC), FAMACHA©, and body weight, using data from Katahdin rams in their annual ram test. Data from 576 rams from 23 contemporary groups were utilized. Fecal egg count and FAMACHA© were measured at 14-day intervals for 70 days from 2012 to 2018.
