Nice to see more people waking up to this and sharing the message.
There are very valid reasons to some vaccinations in livestock. Thinking otherwise is guaranteed to lead to disaster eventually--I say this with my herd currently at risk unvaccinated. Knowing the risks one takes is more important than just blindly being vax free--same applies for humans. (I'm not pro vax or anti. Form an educated opinion and do what you think is best. If anyone has a strong opinion on this one way or the other, keep it to yourself bc IDGAF.)
Pharmaceuticals are literally unnecessary in grass based production systems on a regular basis. No exceptions. Do it right and you will never need them, except the rare sick animal, which will probably die anyway.
I have found trusted organic mineral and feed sources. They're out there, you just gotta do the work. Best to look for local organic sources and feed mills. Grains should never be fed to a ruminant.
