Logistic regression analysis of explanatory variables test method and sample type including their interaction with the tested antimicrobials on the odds of resistant isolates in faecal samples.

Amox = amoxicilline, Cip = ciprofloxacine, Tet = tetracycline, Tmp/s = trimethoprim/sulfa-methoxazole.Variance random sample effect = 1.561.Variance random pen effect = 0.084.Variance random farm effect = 1.413.

Amox 对应阿莫西灵（amoxicilline），Cip 对应环丙沙星（ciprofloxacine），Tet 对应四环素（tetracycline），Tmp/s 对应甲氧苄啶/磺胺甲噁唑（trimethoprim/sulfamethoxazole）。随机样本效应方差为1.561；随机圈舍效应方差为0.084；随机牧场效应方差为1.413。
