I only feed grass hay, I feed free choice when the weather is real bad. Alfalfa mix of any kind is like "crack hay" for my piggies and they get too hyper and food aggressive on alfalfa. I use "barn dri" as an anti slip agent. Works wonders. You can throw it on glare ice and walk on it right away. I keep a tub at the house and throw it in front of my feet when I walk on ice. I dust around the paddocks when it is slippery out. Good for doggies and yard too. We use for our dairy cows. Cant beat the stuff and it is very cheap. Not sure if it is a local product. Martins barn dri Love it.
