It's the most direct "there is no good reason to use this" ban.
There's really three reasons to use antibiotics in livestock:
1. Growth promotion 2. Prophylaxis 3. Treating disease.
The ban hits #1. #3 really doesn't deserve to be banned - it's a legitimate use of antibiotics in veterinary medicine. #2 is where there's still a problem, because the use of antibiotics as a preventative runs the gamut from a perfectly legitimate veterinary intervention to an egregious misuse of antibiotics depending on the circumstance.

It's not a particularly aggressive action but it probably clears the 'nothing' bar.
