.... I heard, at a seminar a couple of weeks ago, that it would take
about 40% Yucca extract in a pig diet to reduce the level of ammonia in
the animal's gut to the levels claimed for commercial feed additives.

It seems that Yucca extract is a very popular product :-)

Does anyone know _how_ Yucca extract came to be used as a feed additive?
