Round bales of hay and straw (which is a very valid source of feed often ignored by many) are often fed to cattle this way. Almost any place where someone has to wear warm clothes to work outside you will often find it done this way. That would be my definition of warm clothing, not yours. LOL
There is also a method called swath grazing where the feed - usually oats or the like, is cut and NOT baled - but left lying in the field for the cows to eat. Works well in many areas until the snow gets deeper than the cows eyes, or there is a hard crust on the snow. One solution to this is to run a few horses with the cattle to break up the swaths. But that is another topic I suppose.
My casual observation from reading on this site kind of goes look like this: People who feed one or two bales of hay often call them "rolls" - people who feed hundreds usually call them round bales.
So - search "bale grazing" on this site - all the methods used, all the cost savings, all the naysayers, all the technical crap, all the philosophy crap, all the "cost of a wasted blade of hay" vs "manure benefits" and so on - you can read it all.
It has been discussed to death
Been feeding cattle like this for more than twenty, maybe even thirty years. So I would say yes, it works reasonably well.
Best to all
