Characterizing the parasite challenge of meat goats grazing summer pastures in Western Maryland,[object Object],SUSAN SCHOENIANSheep &Goat SpecialistWestern Maryland Research & Education Centerwww.sheepandgoat.com – sschoen@umd.edu,[object Object]
Western Maryland Pasture-based Meat Goat Performance Test,[object Object],Established in 2006 to evaluate the performance of weanling goats on a pasture-only diet with natural exposure to internal parasites.,[object Object],Early June through late September,[object Object]
Central performance testing,[object Object],“A central performance test is where animals from different herds are brought to one central location where performance is recorded. The rationale is that measured differences are more likely due to genetic differences, which will be passed onto offspring, rather than environmental differences which will not.  The goal of a central performance test is to identify genetic differences among animals.”,[object Object],                      Dr. Dan Waldron               Texas A&M University,[object Object],2010 top performing buckConsigned by Craig Adams (IL)Sold for $1,350 to PA,[object Object]
Maryland buck testOne of our most important goals is to identify bucks that are more resistant to internal parasites.,[object Object],Resistance = InfectionFecal egg counts (FECs),[object Object],Resilience = TolerancePacked cell volume (FAMACHA©),[object Object],H2 = 20 to 50 percent,[object Object],H2 = 10 to 20 percent,[object Object]
Male goats of any breed or breed cross, born between December 15 (previous year) and March 20 (test year) and weighing 35 to 70 lbs. at the start of the test.  Up to 5 goats per consigner (any state).,[object Object],Eligibility,[object Object]
Number of goats tested,[object Object],Five year consignersDon Smith [L] from VirginiaJeanne Dietz-Band [R] from Maryland,[object Object]
