As others have said it all depends upon how deep the snow it. When you look at the cattle on the ranges out west here they do survive, sometimes, without supplemental feeding. However by the end of winter they are very skinny and weak. Look at the different types of animals in your area such to see if they do well. For the most part you will need to do supplemental feeding in order for you animals to survive. If you take goats for instance the nice things about them is they don't eat much so your storage requirements aren't so much. Start raising horses and cattle then you need barns full of hay. One other thing is cattle will eat pretty much whatever you give them, horses can get sick. At for goats I have always had fresh feed for them so I don't know how they would react to older feed.
