That looks like sabotage to me. What do they use on a dairy that could cause that kind of explosion?

I guess accumulated dust explosion from grain/feed bins could do the trick. Maybe methane from some manure abatement system. Add a spark then boom.The standard FR occam's razor though says eco terrorists.

LOL!

Didn't consider the silo grain-dust. That's possible as well

This. The black smoke billowing up says that an organic combustible was burning after the boom boom. Methane nor natural gas nor propane nor fertilizer would do this.

Farmers should be very careful how they store grains.
