I have a mare that ties up quite consistantly. We have just cut her back to only bermuda grass, no alfalfa, no timothy. She gets one can of Power glo with her supplements, glucosamine, chondrotin, DMG, MSM, trypothan, and ACCEL. In addition, she recieves 1 shot per month of vit E/ Selinium …. any suggestions?

Jessica:

Studies have shown that "tying-up" can be directly related to the total amount of energy a horse eats. Anecdotal reports have suggested that some supplements may help prevent the disorder but scientific studies have been unable to show that any of these supplements (including DMG, MSM, glucosamine, etcÉ) are effective in stopping clinical signs from occurring.

Some cases of "tying-up" have been shown to resolve when treated with vitamin E/Selenium but there is no evidence to suggest that "tying-up" is due to a deficiency of either of these nutrients. My advice is to slowly wean the horse off of Powerglo (abrupt changes in diet can cause illness) and to attempt to feed her the minimum amount of grain at which she is able to maintain adequate condition. I don’t believe that any of the supplements that she is currently receiving is necessary and I recommend stopping all supplements for one month and subsequently having a complete blood chemistry profile performed.

Some horses may "tie-up" as a result of electrolyte abnormalities. It is impossible to appropriately evaluate the horse’s blood electrolyte levels when she is receiving such a variety of vitamin and mineral supplements.

Thanks,
