A study was conducted to identify and compare livestock production and range management practices currently in use in the Texas/Mexico border corridor, and to determine the acceptance of selected innovative practices among cattle ranchers in the State of Sonora, Mexico. Information was collected from private livestock producers who were members of organizations in three different geographical zones in Sonora and from those who were not members of such organizations. The research described a variety of ranch management and livestock handling techniques in use throughout the region, and identified a number of attributes needed to facilitate the transfer of technology among ranchers in the state. The study concluded that agencies involved in cross-cultural education in the state should be aware of cultural values and language barriers in attempting to diffuse technology. A number of recommendations for action and further research were made. (Contains 55 references.) (KC)
