I’ll just interject here – I have had SUPERB results with Cool Calories. My two geezers, 31yo each, both appendix, highly TB influenced QHs, are down right FAT coming off winter.
That said, however, I give them ~6 lbs of grain/2x per day, plus two scoops of CC in each feeding.. a little grain once a day, in my opinion, esp for a TB, is too little. I added the CC to bring down the amount of grain they were getting. They are not hot, course they’re geezers, but have vitality and oomph.
