BRZ FOR POULTRY
PRODUCT DESCRIPTION
Size:
14 x 40, 30 x 60, -40 mesh, 60 cycle
APPLICATION



FEED
This is the most effective point of addition. Many farms have eliminated most of their odor by feeding
between ½ to 2% of the total ration on a weight basis of BRZ™. A 14 x 40 or a -40 mesh product should
be fed in mash or a -40 mesh should be used to pelletize supplements.
BEDDING AREA
A thin layer should be applied to the bedding area or to the area that receives the manure each time it is
cleaned out.
COMPOST OR DRY STACKED MANURE
The compost or dry stacked manure should be “top dressed” with a thin layer of BRZ™ after it is turned
or after the addition of a new layer of manure. Alternatively, a layer of BRZ should be placed in the area
of the barn receiving the fresh manure. Composting is an important process that (1) converts organically
bound nitrogen that is not plant accessible to ammonium hydroxide, ammonium nitrate, and ammonia
that then are plant accessible, (2) kills the pathogens, (3) reduces or eliminates the odor, (4) dries the
manure, (5) reduces the flies, and (6) kills weed seeds. Composting should be conducted “in vessel” to
prevent groundwater and air pollution. Wash down operations are no longer environmentally acceptable
due to groundwater pollution of nitrates, nitrites, and hydrogen sulfide.
STATISTICS
According to Lobo (1999, Feed Management, V.50, No.8, p.16-17) in 1998 layers and broilers consumed 44
million tons of feed in the United States.
BENEFITS
 INCREASED PELLET DURABILITY FOR FEEDS

FLOW AGENT/ANTI CAKING AGENT

INCREASED NITROGEN CONTENT OF MANURE AND COMPOST
BRZ™ increases and fixes the nitrogen in the manure and compost so that it is plant accessible but not
water-soluble. It stops the gassing of the nitrogen as ammonia. Good chicken compost should sell for
$75.00 to $90.00 per ton. Many of the areas that have been repeatedly fertilized with chicken manure
now have phosphate problems. This is a result of not enough nitrogen to balance the plant uptake of the
phosphorous. The problem can be solved by increasing the nitrogen, by the addition of phytase to the
feed, and by feeding BRZ™ to solublize the phosphate in the bird.


BRZ™ ADDS VALUE TO MANURE AND COMPOST
The introduction of BRZ™ with the manure or compost to the soil has the benefit of increasing water
retention, holding the nitrogen and other nutrients in the growth zone, provides a medium for the future
capture of nitrogen, increases the ion exchange capacity of the soil, provides potassium and calcium, and
enhances infiltration and aeration of the soil. BRZ™ is a value added soil amendment that should be
advertised as such.

ODOR CONTROL
Reduces the ammonia gas and odor in the coop and manure storage and compost areas.

FLY CONTROL
Reduced ammonia gas and increased moisture absorption helps control flies.

GROUNDWATER POLLUTION CONTROL
Fixing the nitrogen and various heavy metals reduces the pollution of the groundwater with nitrates and
nitrites.

RECYCLE EGG WASH WATER
Egg wash water can be recycled after filtration through a bed of zeolite granules to remove suspended
solids and bacteria (e.g. E. Coli, etc.).
AMMONIA LEVELS

Effect on Poultry and Humans
 Respiratory tract of turkeys will receive some damage and interfere
with the bird’s ability to clear bacteria from their lungs
 This level is barely detectable by human sense of smell
 Damage to lungs and air sacs is noticeable in 48 hours
 Bacteria and viruses causing fowl cholera, infectious bronchitis and
colisepticema can more easily invade the lungs and airsacs
 Maximum level of exposure allowed for a 10 minute exposure by
OSHA
 Significant lung and airsac damage in as little as 1-2 weeks
 Egg numbers will decline in a month or less in ten weeks
 The sexual maturity of pullets will be delayed and egg numbers will be
reduced once egg production begins
 Extremely dangerous to animals and humans, increased possibility of
permanent damage to respiratory tracts of humans and animals
 Feed intake and body weight will decline significantly over the course
of a month
 Decreased shell thickness and size
 Extreme irritation to mucus membranes in animals and humans
 Dangerously close to lethal levels

CAGED LAYER WASH DOWN MANURE GENERATION, HANDLING, AND PLANT NUTRIENT VALUE
As currently defined for the Environmental Protection Agency (EPA) regulations concerning Concentrated
Animal Feeding Operations (CAFO’s), caged layers with wet (wash down) manure handling have a different
classification than caged layers with dry manure handling as shown in Table 1.
Table 1. Comparison of EPA and USDA Definition of Number of Animals in 1,000 Animal Units.
(from EPA Cost Methodology Report for Swine and Poultry sectors, 2001)
Animal Type
Animal Unit (EPA definition) Animal Unit (USDA definition)

67,000
According to EPA, there are an equal number of wet and dry caged layer facilities with > 1,000 Animal Units in
the U.S. Most of the wash down manure caged layer operations are in areas of the south where freezing
(<28oF) occurs infrequently.
Assumed Food consumption and Manure Production

Caged layers daily consume 2,000-2,600 lbs of feed per day per 100,000 head and daily produce
2,000- 3,400 lbs of fresh manure (moisture @ 70-80%).

Total nitrogen content of fresh manure averages 1.5-2.0 % (@50-70 % moisture), but initial ammonium
concentrations are only about 0.57-0.77 %; the remainder is organic-bound N.

Therefore 1 million hens will produce 10-17 tons of fresh manure (@ 70-80 % moisture) daily.
Wash down Manure Handling and Properties

Liquid slurry (in ponds or lagoons), after 6-12 months storage typically contains 62 lbs of total N, 42 lbs of
which is ammonium per 1,000 gallons. At a value of about $0.35/lb of N, each 1,000 gallons has a
nitrogen nutrient value of $22. If injected into soil as liquid, it has about 80% N availability to plants the
first year.
3

Associated anaerobic lagoon sludge typically contains 26 lbs of total N, and 8 lbs of this is ammonium N
per 1,000 gallon. The value of N in this sludge is about $9 per 1,000 gallons. If injected as liquid, it has
about 60 % plant availability in the first year.

Anaerobic lagoon liquid typically contains 179 lbs of total N (154 lbs of this is ammonium) per acre-inch (of
liquid in the lagoon). When injected in the soil as liquid it has 90 % plant availability.

Many operations will be required to have covers on the lagoons to minimize heat and associated loss of
ammonia (gas).

Addition of zeolite to the fresh manure in small amounts would provide the best chance for capture of
ammonium because fresh material has the highest ammonium N concentration. After washing down, the
ammonium concentrations in the liquid is very diluted.

POTENTIAL SOLUTIONS FOR COMPLIANCE WITH PROPOSED CONCENTRATED ANIMAL FEEDING OPERATIONS
(CAFO) REGULATIONS IN RELATION TO CAGED LAYER FARMS USING STACKED MANURE METHOD
INTRODUCTION
Proposed Environmental Protection Agency (EPA) regulations concerning Concentrated Animal Feeding
Operations (CAFO’s) will force several changes in all large animal/poultry farms in the United States within
the next few years. Several states have already passed statutes concerning regulation of CAFO’s. The
present abbreviated report was prepared to formulate methodologies or approaches to achieve
compliance with the proposed regulations in the most cost-effective manner without significant
interruption of current operations for caged layers used in egg production. A major part of the proposal
relates to integrated use of natural clinoptilolite (a mineral of the zeolite group) for improving poultry
health, reducing ammonia emissions from manure, retaining nitrogen in poultry manure, and thereby
producing a poultry manure product that is valuable as fertilizer and soil conditioner. The CAFO
regulations include handling and treatment of water used in egg-washing.


Reduce ammonia gas (NH3) generation in caged layer residence and manure storage facility by
capturing ammonium (NH4) by ion exchange into zeolite. This is accomplished by adding a small
amount (e.g. 1 wt. %) of zeolite to the layer feed, and adding a small amount (to be determined) of
zeolite to fresh manure. Capture of ammonium by zeolite addition to feed occurs in the gut and some
ammonium present in the feces is exchanged into zeolite added to the fresh fecal material. The
exchange of ammonium into the zeolite protects it from nitrogen (N) loss by alteration to ammonia gas
or other gaseous nitrogen forms.

Reduction of ammonia generation from fecal material will reduce noxious odors and thereby minimize
attention of flies and reduce atmospheric generation of particulate matter (PM10)10-micron-sized
particulate nitrogen-bearing salts that interfere with respiration of humans, poultry, and animals.
Ammonia emissions from litter have been found to be a source of ammonia pollution in acid rain in
Europe.

Isolate and age manure in anaerobic conditions using silo bag containers to enhance heat generation in
order to destroy potentially toxic pathogens, minimize N loss to atmosphere, eliminate rainfall
transport of nutrients and pollutants to the watershed, and remove odor exposure to the local
environment. This isolation might be used to precede composting, either on-site or off-site, depending
upon whether or not it is desirable to emit strong odors on-site.

If composting is desired, aerobic (oxygen-using) conditions are necessary to support and enhance
microbial activity; this requires blowers or fans, or turning the compost with a front-end loader or a
commercially available compost turner. Temperatures in the compost must be maintained at levels
above approximately 130oF (but lower than 150-160oF) in order to kill any pathogens. This composting
will expose the manure to the atmosphere and allow odors and ammonia gas to be emitted locally.
Ion exchange of ammonium from the fecal material displaces potassium and calcium from the zeolite
and these plant-essential elements will be available as nutrients in the manure.


Introduction of zeolite-plus-manure to the soil will have the beneficial effects of enhancing water
retention, increasing ion-exchange capacity of the soil, providing a medium for future capture of
ammonium nitrogen, and increasing aeration properties of the soil due to the high internal surface
area of the zeolite.

Egg-washing water can be recycled after filtration in a zeolite bed to remove suspended solids and to
trap bacteria (e.g. ecoli, etc.) in the zeolite pores.

Phytase added to the food would improve phosphorous utilization, and thereby minimize phosphorous
pollution in the fertilizer application.
TYPICAL CAGED LAYER FOOD CONSUMPTION AND MANURE PRODUCTION

Caged layers daily consume 2,000-2,600 pounds of food per day per 100,000 head and daily produce
2,000-3,400 pounds of fresh manure (moisture @ 70-80 %).

Total nitrogen content of fresh manure is 1.5-2.0 % (moisture @ 50-70 %), but ammonium
concentrations are only about 0.57-0.77 %. [The remainder of nitrogen is in organic nitrogen
5
compounds where nitrogen in unavailable for plant nutrition until the nitrogen is converted to either
ammonia, ammonium, nitrate, or nitrite.]

Therefore 3.5 million hens will produce 35-59.5 tons of fresh manure (moisture@ 70-80 %) daily.
NUTRIENT VALUE OF MANURE FOR FERTILIZER / l 2
For caged layers the average concentrations of N, P2O5, and K2O in fresh manure @ 60% moisture are:
N = 1.8 %
P2O5 = 2.0%
K2O = 1.0%
At 50 % loss of N prior to field application and values per pound @ N = $0.35, P2O5 = $0.23, and K2O =
$0.15, the value of the poultry manure contribution nutrients @ 30% moisture after dry stacking is:
N = $ 12.60
P2O5 = $18.40
K2O = $6.00
_______________________
Total =$37.00 per ton + 25%
*This value of the plant nutrients does not include the value of the K in the clinoptilolite.
