How long have you been feeding the Strategy? I only ask because I got a bag of Strategy (pellet form) from a neighbor that was moving at the end of September. I started feeding it to my OTTB mare, fed it through October & into November, &started noticing a significant blah-ness with my mare. Just dull. Could hardly get her to sustain a trot-even as the weather started to get colder. About 2 weeks ago I put her back on Nutrena, which is what I had been feeding. Not trying to bad mouth Strategy, but wondering if this is a fairly new feed for your horse & he just isn’t tolerating it very well?
