Diversity of the faecal microbial community in four groups of samples; as measured by the Shannon’s Equitability, the inverse Simpson Index and the Shannon Index. Boxes indicate the 25% and 75% quartiles with the bar showing the median. Whiskers mark the quartiles ± 1.5 IQR. Alpha diversity of sample groups was compared using the Wilcoxon signed-rank test. Where significant difference in diversity measures were found, asterisks indicate the p value: * indicates 0.05 > p = > 0.001, ** indicates p < 0.001
