Extended Data Fig. 8. Critically important AMU and welfare costs of UK breed-to-finish pig systems.

Critically important AMU is just use of those antimicrobials most important to human health – Category B use according to the European Medicines Agency. r_s and p values are from two-sided Spearman rank correlations on a subset of our data (n = 43) with one datapoint selected randomly from those that shared breeding and/or rearing herds (see Methods).
