Comparisons between effects of two defaunating agents (sodium lauryl sulfate [SLS] and dioctyl sodium sulphosuccinate [DSS]) on values of different rumen protozoa examined in goats. Within each box plot, vertical line indicates median, black symbol indicates mean, and error bars represent standard error of mean. Within the same parameter, data with different lowercase letters differ significantly between defaunating agents at p < .05 if bold.
