Calmers - Why are so many being used?

[YasandCrystal]

Please reread my post and you will see i was talking about how protein isnt an energy source. Horses do not use it for energy so high protein doesnt cause excitabilty. Obviously any nutreint in excess is going to have some kind of detremental effect on any animal. This is why diets should be balanced.

I am shocked that your feed was 21% protein. Which one was you using? Most respectable feed companies use a protein level of between 10-15% and slightly higher 16% for youngstock feeds.

I was feeding Copra - coconut feed which is widely fed in performance horses particularly the racing industry. I initially thought it would be good as it contains no cereal, however there are very big down sides to it as I found out. I won't mention the brand, but i think there is only one UK brand.
I hear what you are saying, but my boy's temperament was adversely affected - hyper sensitive and aggressive on this feed.
