It's not only cheaper to feed animals antibiotics, but it also makes the animals put on more weight quicker, which is monetarily beneficial for the farmers/companies in the industry. From whatever I have read (over time), this is a routine practice in most places around the world. Unless serious action is taken around the world to reduce or eliminate this practice, the disturbing predictions on untreatable epidemics may come true within the next couple of decades (there are already thousands of people dying every year because their infections cannot be treated with the antibiotic arsenal we have).
