Fig. 2From: Effectiveness of alternative measures to reduce antimicrobial usage in pig production in four European countriesCorrelation of the achieved TI200d reduction. Herds with a higher AMU before intervention achieved a larger reduction. Legend: Correlation between achieved reduction of the treatment incidence of growing pigs from birth to slaughter with a standardised life span of 200 days (TI200d after-TI200d before) and treatment incidence before (TI200d before) intervention in Belgian (n = 14), French (n = 20), German (n = 25) and Swedish (n = 9) farrow-to-finish pig herds.
