I am truly ready for my local mass of humidity to move out!! I found the beginnings of mold growth in the horse feed. Fortunately I caught it early and Scout didn't take any of the moldy grain in. Needless to say, the remains of that load has been tossed.
The silver lining of the moldy grain is that now I'm thinking of finding a more suitable menu for Scout. He had been on a very small amount of sweet feed - our feed store calls it 1/3, 1/3, 1/3 Rolled Corn, no brand name, just the feed-store sweet feed. He literally gets one small handful 2x a day when the other horse in the barn eats, purely to prevent mutiny. The amount doesn't even register on my grain scale.
I'm thinking of switching to a pelleted feed. My Dad thinks that a dry pellet will resist mold and last longer than the "gooey" sweet feed, as Scout eats so little of it and a 50 lb. Bag is the smallest I can buy. I'd prefer not to cut out grain altogether, since he doesn't get any other kind of vitamin/mineral supplement (He does have free access to a salt block), and he "expects" breakfast and dinner when the other horse gets his.
Some info on Scout - Ballpark 8 years old, ridden 4-7 days per week as weather allows, medium work/light trail riding, and daily turnout as weather allows (no real shelter from rain or sun in the paddock, unfortunately). He isn't a hot horse by nature, but I don't really need him to have grain-fueled energy at this point. He has free choice hay of good quality when stalled, free access to grass during turnout. Currently in very good weight, a condition score of 4 to 5.
I'm somewhat constrained by what Tractor Supply carries regularly as far as what is readily available in my area. I was looking at Blue Seal's Strider formula (11% min. Crude protein, 3.5% min. Crude fat, 7.0% max. Crude fiber) as a potential candidate.
Opinions or advice on what to switch to? As I said, the grain is essentially his supplement, and I'm looking to get away from the sweet feed and not have him hopped-up on high octane horse feed.
Sorry that got so long... e-cookies for reading; trying to cram in unnecessary info, as always. Thank you in advance, and let me know if more info is needed!
