Absolute quantification of the Escherichia coli population by qPCR. a Relative abundance of the Escherichia genus as a function of the number of E. coli/g estimated by qPCR. Each point represents a sample. Points on the x-axis represent samples for which no 16S rRNA gene sequence of the Escherichia genus was detected by sequencing. b Dynamics of the mean observed and predicted number of E. coli/g for each farm in the final model without the antibiotic-treatment effect. The mean values ± standard deviations of the observed data for each farm at each sampling time are represented by the dashed bars. The model-predicted profiles and their 95% confidence bands are represented by the solid lines and bands, respectively. The predicted profiles of farms A and C are overlapping, which is why the predicted profile of farm A does not appear. c Dynamics of the mean observed and predicted number of E. coli/g for each farm in the final model with the antibiotic-treatment effect. Antibiotic treatments during sampling or within 15 days before sampling are color-coded by farm and indicated above the x-axis. d Temporal dynamics of the recommended dose of milk powder per kilo of live weight for farms B and C
