Always read your labels and listen to your horse....

My little princess is slim, and in the effort to provide her with enough calories to maintain a body condition score which will allow her to complete longer rides and multidays, I may have over fed her a bit...Now she is normally hot, but not goofy.  At MRRT, she became a goofy little monster, and I began to ponder why.  I am by no means an expert in anything, but I do know how to do research and I do understand the biology of how the horses body works. 
Buffy is the pickiest eater that I have ever seen, so that makes it an even greater challenge to find foodstufs that provide her with usable energy.  I have been feeding her Ultium by purina, but like a dummy, I looked at the claims with out analyzing the ingredients.
Here is the booklet, it is pretty and shiny, which is probably why I ignored the obvious..

But when you look at the ingredients you will see that molassas and alfalfa meal are at the top of the list of ingredients.

The literature provided by Purina indicates that Ultium is a dense food that gives quiet energy, I think that it is because beet pulp is at the top of the ingredient list.  They also recommend feeding a horse Buffy's size 6 pounds a day, I only gave her 4....It is well known that molassas and alfalfa contribute to anxiety and "hotness" in some horses, and evidently mine!  So I consulted the "Picket Creek Guru's", did some extensive research on my own and came up with the following plan.....I cut buffy's daily ration of Ultium by 2/3's so now she is getting 2 cups ultium/4 cups beet pulp/1 handful of rolled oats on days that I ride her.  On days that I do not ride she gets 1 cup Ultium/3 cups beet pulp/smaller handful of oats.  I also added some magnesium and vitamin b complex.  The B vitamins are very important and have many functions!  Among them helping to convert food to fuel and helps the nerve impulse function.  Another thing that I am exploring is another brand of feed.  Triple Crown Nutrition has several products that look promising to me, I have chosen thier low starch formula because it does not have any molassas or alfalfa, but contains fenugeek seed which horses seem to love!

But although the literature states that it can be used to replace part of the forage ration, I do not intend to use it for that purpose...If her royal Buffiness decides to eat this new formula, I will begin to transition her over, which will further decrease the alfalfa and molassas, virtually totally eliminating them from her diet!!! I do see a big improvement in her attitude and look forward to no further "crowhopping" episodes!  Here is the carbohydrate break out for the various formulations of triple crown feed.  Another andvantage to this brand of feed is that they put probiotics into their formulations.

*Values determined by Equi-Analytical Laboratories, Ithaca, NY, reported on as sampled or as fed basis. WSC is water soluble carbohydrates, ESC is ethanol soluble carbohydrates, NSC is nonstructural carbohydrates and NSC = Starch + WSC. Select horse feeds and forage with low Starch + ESC values for horses to prevent laminitis, tying up disease (EPSM, PSSM, RER), prevention of Developmental Orthopedic Disease (DOD), calmer behavior and reduced insulin resistance for Equine Metabolic Syndrome and Equine Cushing’s Disease. Also, forages with high NSC values (fructans) are more likely to cause laminitis. All Triple Crown Feeds have fixed ingredient formulas, values reflect an average analysis of multiple feed samples.
