Re: [RC] Yucca in horse feed - illegal? - Elizabeth Walker

Just to complicate things, it turns out that yucca is allowed by USEF - I was curious, so I sent off an email. Their reply is below. While AERC doesn't need to operate under USEF rules, what about endurance riders in FEI rides? Or is that yet another set of drug rules?

-------
Dear Elizabeth,

Yucca is permitted under the Therapeutic Substance Provision of the USEF Drugs and Medications Rule.

Sincerely,
Diana Tartal

Clearance times don't really apply in this case, as the problem is the horse feed itself. The yucca is in a vitamin/mineral/probiotic additive that is manufactured by AllTech (2010 WEG sponsor), and is added to all of the Triple Crown feeds to provide a balanced vitamin/ mineral profile. So - Triple Crown Senior, Lite, and all their other feeds have it in them.

Withholding it means that you have to change your horses diet to an all-hay diet the week before, and during a competition, which isn't practical.

(I find it ironic that the company that is sponsoring the 2010 WEG makes the product that Triple Crown adds to their feed, and which contains an AERC banned substance.)

Yucca is on the AERC list. If you go to AERC.org, then to the membership
drop-down, then rules & regulations, the appendices list the banned drugs.
I'm not sure where I got this information, but I remember that Yucca
clears from the horses system in three days. Someone else might have good
information on this. It's not on the list on the AERC site that tells how
long compounds remain detectable.

Evidently.


I contacted Mellisa Ribley about it, as I recently switched to Triple
Crown. (Didn't even notice the yucca until it got pointed out.)
According to the answer I got - Yucca is on the prohibited substance
list, as it has anti-inflammatory properties, and there is no way to tell
how much of it is in the feed in a non-FDA approved feed. "The
recommendation is to use these products/feeds with caution during
competition as it is the rider/iowners responsibility as to what is
present in the horse during the time of competition."


I haven't contacted Triple Crown yet, though someone else reported
that their rep said it "wouldn't test". The yucca isn't added for its
anti-inflammatory action. It is added because it will bind with ammonia
in the large intestine, and be excreted in the manure, rather than in the
urine. From their web site:


----
One of the most common feeding errors is over-feeding protein. A small
amount of protein is converted to energy, but much of the excess protein
produces high levels of ammonia in the large intestine. Ammonia absorbed
into the blood inhibits performance due to increased joint unsoundness,
abnormal electrolyte balance, decreased immune response, and poor energy
metabolism. The yucca extract binds with the ammonia and passes it out
through the feces without allowing absorption into the bloodstream and
subsequent release through the urine. A beneficial side effect of reducing
urine output of ammonia is air quality improvement. This reduces
irritation to the horse's respiratory tract and reduces complications with
air passage disorders. -----



This one just irks me, as I don't like the idea that a drug rule would
discourage or prohibit me from buying a horse feed that I thought was the
best value / quality / what have you, for my horse. Gee - maybe we ought
to ensure that we only allow our horses grass pasture and water, as that
is the closest to a horses "natural potential". Oats, high-powered
grains, fats, electrolytes - all of that enhances our horses competitive
ability, too!

OK, I just got a new horse (see ya at OD!), and he has been eating
Southern States Triple Crown Complete, which has in the ingredients
list "yucca schidigera extract". Is this a no-no?
