A pasture-based meat goat performance test in Western Maryland Susan Schoenian and Jeanne Dietz-Band Western Maryland Research & Education Center Maryland Cooperative Extension http://mdgoattest.blogspot.com
Assumptions Most meat goat kids are grown out on pasture. Grain feeding is generally not very economical for meat goats, and this will become increasingly so. Most producers select goats on the basis of how they look, not how they perform. Internal parasites (worms) are the primary health problem affecting meat goats and have a major impact on their on pasture.
Objectives Measure genetic differences in meat goats consuming a pasture diet with natural exposure to internal parasites (esp. Haemonchus contortis ). Evaluate meat goats for growth performance, parasite resistance, and carcass merit under pasture conditions.

Central laneway: goat always have access Three 6 x 11 ft. port-a-hut shelters Water troughs Mineral feeders Handling system with work platform.
Test Protocol Up to 50 male goats accepted. Any breed or breed cross Born Dec 15 - March 15 Vaccinated twice for CD-T Hooves trimmed Health papers issued within 30 days of test No signs of foot rot, sore mouth, or abscesses. Scrapie ID
Management Managed as a single herd on pasture No supplemental feed Free choice minerals with Deccox® Rotationally graze among five 2- acre paddocks of cool season grasses. Access to central laneway containing shelter, water troughs, mineral feeders, and handling system. 14 wethers were added to the herd and removed in August. Checked at least daily.
