Many animals such as hogs and poultry need preformed protein from plants and animals. Ruminant
animals such as dairy cows, beef cattle, sheep, goats, etc have microorganisms in their first stomach
(rumen) that make protein from simple nitrogen compounds. They convert the non-protein nitrogen
(NPN) to ammonia and then convert the ammonia to amino acids, which are then converted to proteins.
The benefit of adding NPN (primarily urea) is that it is less expensive than feeding protein nitrogen. One
pound of urea contains as much nitrogen as five pounds of high protein feed such as soybean oil meal.
High feed rates of NPN result in the generation of large amounts of ammonia that are adsorbed into the
blood and create a change in the acid-base balance of the blood. This creates the following toxic
• Bloat - from excess ammonia
• Labored Breathing - occurs when the animal tries to correct the acid-base imbalance by adjusting
blood carbon dioxide levels
• Lack of Coordination when the electrolyte imbalance affects the brain
When zeolite is fed to the animal it adsorbs much of the ammonia generated from the NPN. It acts as a
reservoir and slow release mechanism for the nitrogen. This can allow the feeding of up to 4 to 6 times
more NPN.
During rumination, a portion of the contents of the first stomach is returned to the mouth for additional
chewing and saliva additions. Saliva introduced during mastication contains sodium which replaces the
ammonium. This results in the slow release of the un-reacted ammonia which is then converted to
protein amino acids by the microorganisms.
Zeolite also provides a reduction of dicalcium phosphate by up to 50% therefore providing a health benefit
and pollution prevention. Presently, the most common approach to cutting dicalcium phoshate is to feed
Feed Operations:
Feeding Calves
Studies have shown that clinoptilolite added to the feed of young calves improved their growth rate by
stimulating their appetites and decreasing the incidence of scours and diarrhea. Five-percent zeolite was
added to a normal grass and hay diet of 10 and 184 day old heifer calves over a 180 day period. The
animals on the zeolite supplemented diets gained 20% more weight on average than those in the control
diet. Although the test calves consumed more feed, the feeding costs per kilogram weight gained were
significantly less than the control group. The test animals’ manure contained less water and fewer
particles of undigested solids. The overall health of the test animals was also notably better than the
control group.
Another study was done using 2% clinoptilolite, 72% digestible nutrients and 11% crude protein over a
329 day period. This study showed the final weights between the experimental test group (using zeolite)
and control group were similar, however, the experimental test group steers showed larger body
dimensions and reportedly dressed out to give higher quality meat. These differences were reflected in
higher prices obtained for the test animals and a 20% greater profit.
5 Ways using Zeolite is Better than Bicarbonate:
• University and field research trials have proven the efficacy and favorable performance of Zeolite over
sodium bicarbonate.
• Zeolite is soluble in water and acid, so it is not flushed from the rumen as quickly as sodium
bicarbonate.  Zeolite continues to neutralize acid even in the lower gut.
• Zeolite releases magnesium and calcium, so it can replace most if not all of the magnesium supplied by
magnesium oxide.
• Zeolite does not adversely affect the palatability of feed.
