This reaction was exactly what Dr. Ridgeway was referring to in his clinic
I attended some years ago.
He stated that he had seen several instances of hypoglycemiac horses from
large amounts of grain.

While this is good in theory, I can tell you from personal experience that
I cannot consume a high carbo food source, like Power Bar's, during
exercise. If I eat a power bar I will get sick. I can eat a candy bar, I
can eat fruit but I cannot eat a power bar. Since I have found an
electrolye supplement that does the trick for me I don't use "sports
drinks" so I can't comment on their effect.


It seems to me that there is a delicate balance of feeding during a ride
that is unique for each horse. My goal in feeding is to keep the gut
moving. So I have before my horse feed ( a small portion of beet
pulp/grain mixture mixed with water, carrots and apples) and hay (alfalfa
and grass). This is not to replinish the energy but to keep the gut
moving so she will have access to the energy stores in the gut.
