Do cow eat plant

Absolutely! Where cactus is plentiful, the thorns can be burned off with a propane torch (pear burner) for a supplemental winter feed. Cattle also tend to eat cactus during periods of drought, but once they acquire a taste for it, they will eat it any time, thorns and all! This can cause problems, since the thorns can irritate the mouth so much that they have trouble eating anything else.
