Which brings me to one of my pet peeves. Assuming a horse consumes the same
energy content, which will provide more protein: late bloom orchardgrass at
7.6% protein or oats at 11.8% protein? The answer is the orchardgrass
because in order to maintain the same energy input (constant weight), they
will eat more orchardgrass. For comparing concentrates, the % protein is a
reasonable approach, but it breaks down when comparing substantially
different feeds. Because concentrates have higher energy density, higher
protein percentages are necessary for the horse to consume sufficient
protein. A better number would be to normalize protein to DE, but alas, you
will have to estimate DE from the ingredients and calculate it yourself.
