Mules have been eating weeds for centuries! Must not be too bad because we still have mules.
Just by way of encouraging *informed opinion*, “certified weed free hay” has nothing to do with the health or nutrition of the animal eating it.
It’s about preventing invasive weeds in natural and pristine areas.
Horses and mules do not digest all the seeds they eat, they pass right on through the horse quite unharmed, and now, fertilized.
Many natural and pristine areas require that horses (and mules) eat weed-free hay prior to and while riding in those areas, to prevent the spread of noxious weeds.
Weed free feed is readily available and horsemen who frequent backcountry and remote areas are familiar with it.
They don’t want the weed seed passing through the mules and ending up being “planted with fertilizer” by the mules passing through pristine wilderness land.
Any excuse to stop progress is a good exceus.
It’s a wonder how they can look themselves in the mirror and still say that they are “progressives”.
Integrity is not one of their strong suits.
