Fig. 1From: Comparison of antimicrobial resistant Escherichia coli isolated from Irish commercial pig farms with and without zinc oxide and antimicrobial usageEnumeration of E. coli counts originating from faecal samples. E. coli counts from faecal samples from AB-ZnO using and AB-ZnO free farms using non-supplemented, apramycin- supplemented, ciprofloxacin-supplemented, and cefotaxime-supplemented TBX agar. Means and standard deviations are indicated in red. E. coli counts between AB-ZnO using and AB-ZnO free farms were compared per sample using the Mann-Witney U test (no significant differences were observed). FW0 = faecal sample at day of weaning; FW1 = faecal sample 1 week after weaning; FW2 = faecal sample 2 week after weaningBack to article page
