Venn diagram showing patterns of antimicrobial use in medicated feed for growing pigs on 67 farms, 2016. Each set contains the farms medicating the given diet category during 2016: starter, link, weaner and finisher. The percentage and number of farms medicating each diet category are shown in parentheses after the corresponding set title. The values within the sets show the percentage of farms (number in parentheses) with each pattern of use. For example, 6% of the study farms (n = 4) medicated the link diet only; 22.4% of the study farms (n = 15) medicated the starter, link, weaner and finisher diets. The values outside of the 4 sets indicate farms that did not use medicated diets
