Zeolite increases feed efficiency and decreases ammonia levels in the
poultry houses. High ammonia levels   decrease gradable egg
production in layers and gain in broiler operations. Various state and
federal agencies are mandating ammonia levels be reduced. Frequently
the ammonia levels in poultry houses exceeds 100 ppm which are
considered close to lethal for humans and animals.
The introduction of zeolite in feed is the most effective means of odor
control in poultry operations. Many farms in North America have
eliminated most of their odor and realized greater animal health,
welfare, and production by feeding zeolite between ½ to 2% of the
total ration (by weight).
A thin layer of zeolite should be applied to the bedding area or to the
predominant manure field.
Increased solubility of phosphate in birds. The zeolite exchanges the
calcium from dicalcium phosphate and makes the phosphate more
soluble and better utilized for bones. The dicalcium phosphate in the
feed may be reduced by 50% after testing
• Increased number of gradable eggs, shell thickness and egg production
• Reduced foot pad burns from phosphorus
• Lowered mortality
• Increased shell thickness
• Increased nitrogen content of manure and compost. Zeolite fixes the
nitrogen in the manure and compost so that it is plant accessible but not
water-soluble. It stops the gassing losses of the nitrogen as ammonia.
Many of the areas that have been repeatedly fertilized with chicken
manure now have phosphate problems. This is a result of a nitrogen
imbalance to the plants in their uptake of phosphorous. This problem
can be solved by increasing the nitrogen, by the addition of phytase to
the feed to solublize the phosphate in the bird.
• Egg wash water can be recycled after filtration in a zeolite bed to
remove suspended solids and bacteria
Aflatoxin Control in Poultry
A research study reveals zeolite to be effective and more than offsets
the detrimental effects of feeding aflatoxin contaminated feed. Broilers
fed 20 pounds of zeolite per ton (1%) of finished feed containing 115
ppm of aflatoxin showed improved feed conversion by 5.8 points and
the body weight by 5.3 points versus the 115 ppm afatoxin control
feed. Broilers fed the zeolite rations containing 115 ppm afltoxin had a
lower feed conversion by 1.1 points and higher body weight by 3.7
points than the broilers fed rations containing no zeolite and no
