too many for your poll. Alfalfa and oil, speedibeet, multivitamins are the base. Extras for each horse as needed (one has cough ease, another U-gard and something for joints) the only commercial product is some cheap conditioning cubes for those that need a bit extra, as we get into winter I will add soaked oats if condition starts dropping
Good quality haylage in winter (and grass in summer) is the basis of my feeding regime. Bucket feeds are based on Alfa Beet - just a handful for my two fatties, a larger portion for the older pony and then added oil and barley for my 7/8TB veteran.
