 From information obtained from these producers, these "selected" Spanish goats appear to greatly outperform the ordinary Spanish goat used primarily for pasture maintenance.When Boer goats were introduced into the United States from South Africa in the 1990s, many producers switched from raising Spanish goats to raising Boer or Boer crosses, which greatly reduced the population of Spanish goats.In 2009, there were approximately 8,500 purebred Spanish goats nationwide.
