Bones from conventionally reared animals

[Francesca123]

I am able to obtain a lot of bones from a local butcher but more than likely these bones will be from conventionally raised cows and not fully grass fed. Thankfully the agricultural practices in my country are quite good so the cows will likely be out in the grass most of the year but are probably not solely grass fed. Are the bones from these animals still ok to make bone broth with?

Thanks

Dr. Peat as I recall warned against boiling these bones for many hours as that will result in more heavy metal leaching.
