I have used it for the past 3 or 4 years. I use Heritage Performance and have had no issues. Horses always look good and run good. They also have a low starch formula that I have used when I have one that has problems with being overweight or too high.
It's good feed, but one of the sweet feeds smells like candy, they love it. I almost want to eat it lol, but too much sugar. You might go with the low starch one if you have a hot horse.
I feed Heritage Senior to my 17 year old that I retired this year. It isn't cheap, but it's cheaper than other Senior feeds. My mare likes it and doesn't get a fed whole lot of it, because she's an easy keeper.
