This work was carried out in order to determine the parameters and productive indexes of the bulls of the ninth test of grazing performance at CORPOICA Turipaná, municipality of Cerete - Córdoba, the following variables were taken into account; Weight gain, daily weight gain, ultrasonography and morphometric measurements, and the production indexes were calculated, then the bull-by-type index (ITT) was calculated using two methodologies, the official grazing performance test for males of Asocebú and One managed by Corpoica in the performance tests for males of native breeds. Finding that the results of both methodologies vary, because they take into account different variables. Both are reliable in determining which are the best specimens. We also compared the historical performance tests in grazing conducted by Asocebú and concluded that the 9th test has been one of the best so far.
