What are your thoughts?
Here's his situation. He's on pasture 24/7 (except when I'm messing with him ). The pasture is just natural, not very lush, stuff to pick at. There are also several grass round-bales available at all times. Right now they mostly ignore the round bales, but I imaging come winter they'll be spending most of their time on them.
Twice/day he gets brought in for a half scoop of feed(*). The feed is a basic grain, no molassas or other sweetener added in, that comes from a neighbor's fields.
He came to me somewhat overweight 1.5 months ago, but is slowly dropping it, as he went from being walked a couple times/week to walk, gait/trot almost daily with some canter thrown in. He's otherwise healthy, but is a cross of two breeds prone to Equine Metabolic Syndrome (Morgan and Paso Fino) - so I keep a close eye out for any signs of that, including checking his digital pulse on all 4 legs daily. Our farrier loves his feet, says they are really healthy and strong. His joints are fine. He's 5 years old, and has never had any problems.
His previous owners did feed him some supplements, but I don't know which ones.
What are your thoughts? Would you have supplements given to a horse in this situation? If so, which ones?
(*)I know "half-scoop" isn't a measurable amount, but no precise method is used - the barn manager goes down the row of 10 standing stalls and throws a small bit in each. It's not to give him any real nutritional value - it's just the basic amount every horse gets to keep them orderly when the herd comes in for meal time. Then once they are all in their spots, the horses who actually need it are thrown extra of that feed, different feed, supplements, and/or medication.
