My girl doesn't get grain, but I would like to supplement her grass/hay diet if need be.
She currently gets an alfalfa/timothy mix hay 3x per day and has access to a mineral block 24/7. She's an easy keeper and could get fat by looking at food.
I ride her 5 days a week: 4 flat hacks and 1-2 jumping sessions per week.
She's got great feet and a healthy shiney coat.
What is a good 'all-around' supplement?
