Post-EtOH extracted whole plant CBD biomass is dried outside and turned a couple times before being given to cattle and horses pretty often on the west coast. THC strains carry through the milk in dairy, so you still have to limit which livestock can be given the silage. We typically had 1-3% of the biomass remaining after extraction, not much, but in a heavily tested dairy op with thin margins, it'd be safer to never use cannabis products or risk a rejected dairy product shipment.
