Horse is a basically healthy six year old Mustang gelding in good weight and light (currently with the Covid situation, EXTREMELY light) work, last weight on scales 1050 lb a few months ago, no visible changes in weight/condition since that weight. On his previous diet (before recent change) his hoof quality has been excellent, hair quality as expected for being out 24/7 in Texas (fades badly in sun).
I recently moved my horse to a situation where I have more control (and responsibility) over what and how much he’s eating. Previously he was on field board so he more or less ate what everybody else ate (free choice Coastal from a round bale and SafeChoice Maintenance, access to a generic salt block; I was also giving him Uckele Copper and Zinc pellets when I would go out, 4-5 days a week, treats of various kinds when I went out). The last couple of months, on the advice of our vet, we removed the grain and all treats to see if his behavior improved (he’d been getting weirdly reactive). It has, without making him “dull” or lose weight, AND we recently moved to a setup that’s a stall-and-run, solo night turnout, so I’m in a position to add in the items the vet suggested to round out the coastal hay diet (now from small squares, if that makes a difference), without having to supplement everybody else’s horse in the field, too, or pay a premium to have my guy brought in to be fed separately. What was suggested was to add in half a flake of alfalfa in the evening, a “flax based supplement like Platinum Performance” and a fat supplement (if needed). I also plan on offering free-choice loose salt. Hay analysis is unlikely to happen any time soon, unfortunately, and I’m unlikely to be in the know regarding when a new shipment comes in that would need re-testing.
So, is PP really the best option here? Glanzen 3 seems superficially similar, and is cheaper. What are some other low-NSC general supplement or “ration balancer” out there that would reasonably balance out common coastal hay deficiencies and be palatable either on its own or mixed with hay pellets? Anything I could use that would let me drop the Cu/Zn or is it a good idea to keep up with that (he has horrible sun fading, although maybe that will be less of an issue with more shade access)? If he starts losing a bit of ground and offering more hay doesn’t fix it, what’s are some good fat supplement options? Finally, should the salt be iodized or non-iodized? The iodized is certainly easy enough to pick up cheaply. I’m not going to pay through the nose for some “horse” himalayan salt if I can get a big sack of Morton’s at CostCo.
Thanks in advance for any advice!
