I could not get any grass-fed bones today. I also cannot get organic hormone antibiotic free bones where I live.
All the bones come from regular mistreated cows full of antibiotics and hormones. I do not live in the States so those cows are treated pretty bad here.
Is it even worth making bone broth or not? Will the benefits of making bone broth outweigh the negative side effects of all those hormones and antibiotics?
Thank you for your answer!

There are regulations that stipulate a "withdrawal period" so as to allow administered antibiotics to clear from a treated animals system. I am by no means confident that these regulations are always followed, but nevertheless, it is supposed to be practiced.
The amount of antibiotic residue also varies from animal to animal (pork more than beef for example) and also on an individual animal basis (not all animals receive antibiotics at the feedlot).

Speaking of "excreted", I think most people are unaware that veggies (even organic ones) can contain livestock antibiotics...
"Around 90 percent of these drugs that are administered to animals end up being excreted either as urine or manure," said Holly Dolliver, a member of the Minnesota research team and now a professor of crop and soil sciences at the University of Wisconsin-River Falls. "A vast majority of that manure is then used as an important input for 9.2 million hectares of (U.S.) agricultural land."
My take is that CAFO cows are still cows. Still have bones and connective tissue and knuckles... just skim the scum and fat.
My mom makes traditional Korean bone broth from conventional whole cuts of beef with the bones still in, as well as oxtail soup. Although it's not the most ideal choice and I'd rather be able to buy grass-fed, we can't afford it... and it's still nutritious. I've never felt sick after eating bone broth from conventional cattle, and you still reap benefits from it.
Good luck. :)
