a specific gravity between about 0.3 and 2.0 and
comprising:
(a) a core comprising bioactive substance;
(b) a hydrophobic coating encapsulating said core in
a
quantity sufficient to essentially preclude introduction
of
bioactive substance into the rumen; and
(c) a surfactant applied to the surface of the
hydrophobic coating in a quantity sufficient to ensure
that
said particles do not float on the rumen.
26. A composition of matter comprising particles
suitable for introduction of choline chloride to the
post-rumen portion of the digestive system of a ruminant
substantially without introducing choline chloride to the
rumen portion of the digestive system, said particles
having
a specific gravity between about 0.3 and 2.0 and
comprising:
(a) a core comprising approximately 70 percent by
weight choline chloride on a cereal carrier; and
(b) a hydrophobic coating encapsulating said core in
a
quantity sufficient to essentially preclude introduction
of
choline chloride into the rumen
Discussion
1. Rejections over Ghebre-Sellassie
Ghebre-Sellassie (G-S) describes (G-S, col. 1, l. 59-68):
. . . a water-dispersible formulation of gemfibrozil
. . . in which finely divided particles of pure
gemfibrozil
are uniformly coated with a mixture of a wax and at least
