Oaxaca has 1 159 653 goats and is the technologically. Therefore goats represent an primary producer of goats in the country important alternative in meat production, (INEGI, 1989). gaining greater relevance in the last few years At present goats are the most important because they can be bred in areas where other option in meat production in the Mexican species cannot. countryside. The Mixteca region (which Dairy goats are not very common in the covers part of the states of Puebla, Guerrero south of the country, meat being the main and Oaxaca) is second in caprine production product (Mouat, 1980).
