To characterize the properties currently served by the program will be offered a questionnaire to the producers and that the variables were divided into five groups: "selection", "technology", "reproduction-tion", "flock" and "Fam surface." Which evaluated the effectiveness of the program, noting that the most important group was the "selection" which showed a marginal importance within the formed dimensions, but it is systematic.
