Feeding and antibiotic administration timeline. Numbers indicate day of the feeding period and B, C, D, and E represent points where fecal samples were collected from cattle. Silage-based diets were fed for 115 d, followed by 21 d of transition to the grain-based diet, which was then fed until shipment of cattle to market. Shaded areas indicate the periods that antimicrobials were included in the diet.
