Some of the following benefits are well accepted
and are not referenced in the bibliography.
Other benefits that BRZ™ cannot claim due to
U.S. Government restrictions can be found in the
publications listed in the reference section.
AVERAGE DAILY GAIN (ADG)
The CEC of the zeolite allows the exchange of
ammonium from feed stuffs upon digestion. In
cows, the ammonium is released when it comes
back to the rumen (sodium from the saliva
exchanges with the ammonium) and creates a “time
release” of the ammonium for better utilization
of the nitrogen. 3, 6, 7
CONVERSION RATE REDUCTION
The conversion rate of feed to gain is decreased
due to better utilization of the nitrogen.
3, 6, 7
Feeding low sodium clinoptilolite mediates rumen
PH. 2, 3
Zeolites effectively absorb mycotoxins
containing polar groups such as aflatoxins.
Zeolite’s binging and desiccant properties also
dysentery. 2, 7, 8, 10
ODOR AND MOISTURE CONTROL
One of the major causes of odor from animals is
the generation of ammonia gas from urea and
manure that become the aerosol for odors. BRZ™
captures ammonium and prevents the formation of
ammo0nia. BRZ™ zeolite holds 55% of its weight
in water, an attribute that results in dryer
stalls and a reduction in manure fly pressure.
MANURE HOLDS MORE NITROGEN
In 30 days the loss of 30% nitrogen in the
manure was cut to 10% by feeding clinoptilolite.
Zeolite exchanges and holds ammonium before it
oxidizes as ammonia. 3
MILK PRODUCTION INCREASED
Proper amounts of zeolite in the TMR enhance
HEAVY METAL REMOVAL
Feeding zeolite removes heavy metals from the
rumen, such as 91% of lead, 45% of cadmium and
many other metals. 7, 11
The risk of toxicity due to the increase in PH
and ammonium levels in the rumen is mitigated by
using zeolite. 1
DI-CALCIUM PHOSPHATE RATION REDUCTION
When fed to an animal, the zeolite exchanges
with the calcium in “di-cal” to help solubilize
the phosphate. The net effect is that the di-cal
ration can be reduced because the phosphate is
better utilized and the bone growth is enhanced.
