I can't figure out how to add a salt lick, so ignore the red sodium bar and I'm leaving the selenium since I don't have a hay analysis for the new hay yet
Nutrena is not the friendliest brand in terms of NSC. They do like that sugar. The lowest one I found was 15%, SafeChoice Special Care. For comparison, Theo's currently on Carb-Safe with 5.4% NSC. Carb Guard comes in at 11% and he was on that with great results for years.
Theo doesn't have any metabolic concerns, his low carb lifestyle originated from some of his bad behavior. Way back when he was a lesson horse they had him on a cheap grain that had a lot of corn and molasses, something like 33% NSC. I swapped him to Carb Guard to see if that took down some of the fizzy, reactive behavior. Sure enough, we had less trouble under saddle so we kept with it. He's enough of a bratty toddler without adding a bunch of sugar.
The new barn's default grain is Nutrena ProForce and while it's not crazy sugary, it's a lot more than Theo's seen in years. I really don't want to see him hit the rafters and act like a child that was left unattended in a candy store. Or colic. His system just isn't used to it. He'll also be seeing less fiber and more protein. He'll be on free choice hay so I'm not that concerned about the decreased fiber, but I'm eyeballing that protein while figuring out just how much demon I might create with a feed change.
Not to be trusted
Once he's settled, I'd like to move him to 5 lbs of grain a day and see how that works. With 5 lbs of SafeChoice, I can actually take him off the multi-vitamin he's on and reduce his supplement bill. SCORE. I'm thinking about moving him to Cosequin ASU, his selenium supp, MSM, and biotin. That's it. With 5 lbs of SafeChoice, I'd actually have all of his bases covered.
This is totally normal, right? Spending most of a working day balancing your horse's diet?
