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

But that is USEF, not AERC. So - while it may not impact the WEG, it does impact grass-roots AERC competitions.

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.

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

Southern States Triple Crown Complete, which has in the
ingredients
list "yucca schidigera extract". Is this a no-no?
