I was talking to someone from Coolstance about their Coolstance Copra and asked them if I should keep feeding my one gelding as he is staying fat and whether or not I should switch him back to the Renew Gold.  Told him that I also fed the Omega Complete cubes (alfalfa/flax cubes) and he told me that alfalfa was basically hay for cows not horses.  I had not heard that before.  I thought alfalfa was good for horses.  

I personally have seen significant advantages from alfalfa as a tool in a balanced equine diet for over 40 years. There are very few times that a horse will not benefit from some alfalfa. As support for low protein hay, offsetting grain rations that provide too much phosphorus, buffering stomach acid in ulcer prone horses, replacing an unnatural amount of grain based feeds, PSSM horses, and a whole lot of other situations, some alfalfa in the diet is a good thing in my opinion.

Well that's what I thought.  

Thats pretty much the general opinion of the Coolstance people that you have to go thru in the US to be a dealer.  I think its a bunch of bull to be honest, lol.  Alfalfa is good, has been fed to horses very successfully for decades, not sure where they get the "cow hay" opinion but whatever.

From what I thought is that they give alfalfa to horses that have gone through colic surgery.

They do. After my sister's gelding's colic surgery MANY years ago, she was instructed to only feed senior feed and alfalfa hay while he was recovering.

There are zero facts behind their stupid opinion.
