The in-feed use of the antimicrobial drugs tetracycline and bacitracin in poultry is shown in the graphs below.  What is the best explanation for these trends? Image description: These graphs show the change in the usage of tetracycline (top graph) and bacitracin (bottom graph) over time in broiler feed (chicken feed). The x-axis spans from 2013 to 2017. The y-axis for both green bars and red line shows the amount of the drug used. Tetracycline use was highest in 2013, lower in 2014, and very low in 2015-2016. Bacitracin use was higher than tetracycline use and was used at similar levels from 2013 to 2017.
