Why are Thai farmers feeding cannabis to chickens?

Because it's incredibly rich in fats, proteins, starches and a host of micro-nutrients. The seed especially is a nutrition bomb, and lots of animals love to eat cannabis. As the article makes clear, these are leftover scraps that would otherwise probably be composted, so why not try to convert it into eggs and meat?

I hope it works!

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.

I’m sure the seeds would make great chicken feed.
