I have been using Mitavite feeds for all of my horses, 4 stock horses in varying amounts of work and ages. My broodmare is on Hygain at the moment because I could not get the mitavite feed for her My firey little polocrosse mare, along with my partners ever trusty gelding and our 2 year old gelding are all on x-tra cool. And they all get copra as well, because they like it! Along with black sunflower seeds, oaten chaff and lucerne chaff, and some stockgain to help wet it all down. Now the firey little mare (who is 18) gets hot on the x-tra cool. I have had to swap her onto Pegasus Coolmax, which does not heat her up at all. BUT I prefer the quaility of the mitavite feeds compared to others. Does anyone feed any of the other feeds, such as the cool performer, which perhaps does not heat their horses up? I tried her on gumnuts becasue of her age and it sent her tropo! I have also tried her on whole grains with the same effect, which of course doens't make sense with the Coolmax!
