As a senior veterinary student a few years ago, I watched as veterinarians handed out antibiotics to farmers on large farms by the truckload. Since becoming a veterinarian myself, I've learned this experience was not unique. The majority of these antibiotics are given to healthy animals for the purposes of disease prevention. When given for these reasons, the antibiotics do not neutralize all of the target bacteria — providing the perfect environment for the emergence of resistant bacteria. More antibiotics used for these purposes will only result in more antibiotic resistant bacteria.
