Effect of equine type on the fecal bacterial (a), anaerobic fungal (b) and archaeal (c) concentrations on a dry weight basis. Columns represent the mean (n = 18, except for zebra where n = 16) and error bars the SEM. Letters above the bars within each plot indicate significant differences (P < 0.05). Percentages stated on the x-axis in brackets indicate how the mean of each equine type compared to that of the horse.
