Don't have any good pics because of weather issues but my gelding gets about 2 lbs maybe a little more of sweet feed in the winter, grass hay all the time and then has supplements out in the field. During the summer the sweet feed is cut back a lot or non existent and he just gets the hay, grass, and supplements.
As for his activities he's outside year round rain or shine and NEVER comes in (his choice). That keeps him active and fit. Then I ride him about three times a week and do training two other times in dressage.
