  2. Breed Resource Evaluation at Virginia State University • Species comparison of meat goat and hair sheep breeds • Evaluation of breed types within species • Goats: Nubian, Spanish, Myotonic, Pygmy, Boer x Spanish, and Boer and Kiko terminal sire kids • Sheep: Barbados Blackbelly, Katadhin, St. Croix Beaver - 2006

  3. Program history • Initiated as Meat Goat Program in 1992 • Changed to Small Ruminant Program 1997 • introduced breeding flocks of Katahdin in 1997 • Barbados Blackbelly in 1998 • St. Croix hair sheep in 1999 • Emphasis on breed evaluation and forage-based, low-input production systems Beaver - 2006
