Diversity of luminal microbiota in jejunum of broilers for different experimental conditionsThe Shannon index (y-axis) was calculated for all five experimental conditions (WA1, WA5, A5, WA14, A14) (x-axis) based on the genus/species level. In total there are 5 treatment-day combinations consisting of up to 8 points, where each point represents 1 pool consisting of 10 chicken. At each time point eight measurements were performed, i.e. the spread depicted here is the average between pens. Abbreviations: WA1, without antibiotic day 1; WA5, without antibiotic day 5; A5, with antibiotic day 5; WA14, without antibiotic day 14; A14, with antibiotic day 14
