As I have read, that’s primarily a difference between pasture and feedlot breeds; pasture breeds mostly do fine without antibiotics whereas feedlot breeds require constant attention.
Also worth noting that antibiotics in meat production is not only about health. For unclear reasons (or at least, it was unclear years ago when I learned about this) giving cows antibiotics just makes them grow much better and fatter. Presumably, there are bacteria that inhibit growth without making the cows visibly sick. Result: antibiotics get deployed to all cows as a general growth enhancer, rather than focusing on actual sickness.
