This has been a busy and challenging summer for me and it's good to finally be back on line - though it will still be some time before I expect to be back in the saddle.
I'd like to invite you to check out some recent updates to my Vitamin E article, “Comparing the cost of providing Vitamin E for our horses” at my website. Thanks to Rob Stuart, Ph.D., President of Stuart Products, Inc. (supplier of EMCELLE TOCOPHEROL micellized alpha-tocopherol) for pointing out some changes which were needed.
If your horses' primary diet consists of cured hay during the winter, they should receive supplemental vitamin E. Current NRC daily recommendations for vitamin E in horses are 1 -2 IU/kg body weight (250-500 IU)which is easily supplied by active pasture but is quickly lost when hay is cut and cured. This is a “minimum” level and may not be adequate for horses with neuromuscular disorders, pregnant or lactating mares and metabolically challenged horses. Vitamin E, although a fat-soluble vitamin, is not stored in the body as vitamins A and D are, so should be supplemented daily when not supplied by the diet.
Dr. Eleanor Kellon has suggested a minimum of 2 IU vitamin E per pound of body weight (or 2,000IU/day for an “average” horse)on a cured hay diet to ensure they receive adequate levels.
I hope you find the updated article interesting and helpful in selecting the most cost-effective vitamin E supplementation for your particular circumstance.
