Awesome product!

We had sold a mare 2 years ago, however, she did not get accepted by the new herd and the owner was concerned because she dropped several hundred pounds over that time. We had asked more than once to get her back then he finally said we could have her back because nothing he did was putting the weight back on her. We told him to buy this product but he never did. We got her back on 7/13/25 and she weighed 713#. She has since gained 70# on this product twice a day!! It is amazing. We used it a few years ago on two spotted saddle bred horses we got who were very ribby and it worked magic for them also. We have the oldest one back on it because he was starting to thin out again and he has gained almost 10# in about 2 weeks. He is 26 years old and a hard keeper but this product is helping!

Hard keeper

I have mobility issues and it is nice not having to go to the big box feed store to purchase and it is LESS expensive.

Love this product and have used it for years with some hard keepers. Young, old and in between. It's been many years since I've needed to use this so was very happy to see Manna Pro has stayed consistent with this product and haven't changed a thing.

Great Product, PICKY Mare

I know this product is good, but my mare wont even stand within 10 feet of her feed if this is in there.

I have been using Cool Calories with great success for years on my lactating broodmares, in order to boost calories without adding volume to the feed. It's always been very palatable to a variety of horses, and when paired with the right feed program, effectively helps maintain weight and body condition under the intense caloric demand of lactation.

Smells insanely bad, horse eats it

This smells so bad I have to breathe through my mouth when scooping it out of the bag. Regardless, my horse eats it and loves it and it works.
