The US has a ton of problems with agriculture, but I find half of people's complaints about antibiotic use in US farming reaching far beyond what is actually happening in reality. I often hear people complain about antibiotics being in their milk or beef, but there are absolutely no antibiotics in your milk because a single cow on antibiotics getting its milk in a 10,000 gallon tanker will cause the entire load to be dumped, and it is tested for in every batch. As for beef, maybe once in awhile, but feeding a 1,200+ pound animal enough antibiotics for months to increase its weight that extra 5% is going to cost you nearly as much as the entire animal is worth.
Poultry is an area where it might be a bigger problem because chickens grow WAY faster than cows and they live in absolutely deplorable conditions on factory farms. Birds need to be clean to stay healthy, and they can't stay clean stacked in little tiny cages or packed into dense flocks, and so they end up dosed with antibiotics because otherwise they need like 10x or more the land/floor area to not have swaths of the herd top die from natural diseases. A cow or pig covered in shit is just a cow or a pig, cow shit is basically dirt by time it comes out the other end it is so thoroughly digested, a bird covered in shit is going to be packed with disease and parasites.

Is this true? I can't find any source for this claim, just some old papers that suggest the number is closer to 30%, and various government sites that imply the practice is still in place around the world.
Im sure there are a few places in India and China that still do it where alfalfa is expensive while antibiotics cost pennies. But it certainly isn't happening in the US where growing grass is as close to free as anything gets but antibiotics cost a decent amount of money. A 800 pound cow is only worth around $250 pounds to a farmer, so even a 30% increase, which is far beyond optimistic, is at best going to net you $75 extra, which is not going to cover the many months worth of antibiotics it took to dose an animal that large.
