The study consisted of post-morten inspection of the viscera, livers, of all cattle. Descriptive and inferential statistics were used to evaluate the trial, using tables with percentages, graphs, averages, coefficient of variation (CV), standard deviation and using the Chi-square test. On average, a weight of 13.57 lbs. Of seized livers was obtained with a standard deviation of 11.67 and a coefficient of variation of 85.99%. There is variability in the data, this is due to the low frequency of occurrence of the disease in slaughtered cattle, of 0.05 and 7 degrees freedom, a referential value of x2t (tabulated) = 14.06.
