[RC] [RC] new topic, hay - Patti

Ultium is a high fat "supplement". If you're relying on fat for energy, it takes up to eleven weeks for the horses system to adapt to using fat for energy. http://shady-acres.com/susan/metabolicpull3.shtml. So it's possible that the horses described might have been experience low blood glucose levels.
If you're relying on Ultium for vitamins/minerals, you'd need to be feeding 4 or more lbs/day to supply minimums (and this only supplies 1mg of selenium). They also list several ingredients which aren't quantified in the guaranteed analysis (iron, manganese, vitamin E, etc). At $2/day or more, it's an expensive way to feed fat and minerals - you could probably do as well with a 50/50 mix of beet pulp and oats with a quality basic supplement and some additional alfalfa, flax and/or oil if needed.

Blood testing alone isn't the best way to evaluate supplement needs -  the body works very hard to maintain hemostasis, so a deficiency may not show up in blood levels until it is severe.  (A thorough discussion of this is available at http://ker.com/library/index.asp, search on "blood analysis" - and see the 7th article by P. Spangfors.) Especially if you don't have a clue as to what's going in in the first place (hay testing).

I too had a similar experience with Ultium.  Eddie, my horse, is  normally hyper at the start, but no shakes or quivers.  On 2 rides where I  used Ultium
he had the shakes at the first vet check.  He pulsed down and  made it through, but never again with Ultium.

My daughter's horse had a major  tie-up several weeks ago.  It was terrible! She is now 3 weeks post  event and still has elevated enzymes.  Several
people emailed me and said  their horses had tie-up episodes while on Ultium.
Please post to the  list your findings as others are experiencing this problem too.  My  prayers are with you,
