I wouldn't feed it all the time but I often give Tilly and Rodaidh a bowl of warm porridge (with goats milk and no sugar) before a shoot rather than their usual breakfast if it's a really cold day. It warms them up and is slow releasing energy, my Stepdad has always done this for his Springers which is where I got it from. They absolutely love it although as I said I wouldn't feed it every day, more as a treat every now and then or if they're working in the cold.
