CHICKEN ODOR CONTROL TEST
STEVE RHODES
CONCLUSIONS by Steve Rhodes
The main reason for this field trial was to see if Zeolite
would lower ammonia levels in poultry manure. It was a ten week
test with manure of various depths to see how well it would work
from the start with no manure to starting with four feet of manure.
We wanted to see if manure that was untreated and then treated with
Zeolite would lower ammonia levels by forming a cap or barrier over
the top of the untreated manure. House # 6 had four feet of manure
at the start of the test. The results showed that the Zeolite was
very effective in lowering ammonia levels. All houses showed
noticeable reductions in ammonia levels. By lowering the ammonia,
we were able to run house temperatures at 78 to 80 degrees and still
be able to maintain good air quality. One of the advantages of this
is that it helped us get a better feed conversion, and we were able
to run our pit fans earlier to help dry manure.

COMMENTS by BRZ (Sponsor)
1. The chickens were fed a mash feed containing 1/2% w/w 14x40 BRZ
(zeolite clinoptilolite).
2. The test was conducted in 8 of the 24 chicken houses. The operator has 3,000,000 layer chickens.
3. The operator will start feeding the chickens in all 24 houses in winter
months and continue to use 14x40 BRZ.
4. The houses are heated only by the heat from the layer chickens.
5. The ammonia level is controlled by numerous exhaust fans during the summer, spring, and fall months. The problem and the reasons for the tests and the usage is that the fans are shut off during the cold winter weather and the ammonia level rises to lethal concentrations. The BRZ is used to lower the high ammonia levels.
6. The operator will be doing additional testing to determine the effect of the BRZ on gradable egg productions.
7. The operator was controlling myco-toxins using a product called T-Bind. He stopped the usage of T-Bind in the houses in which he was feeding BRZ and noted that there was no difference in the effects of myco-toxins (Aflatoxin A) on the birds being fed BRZ and those being fed T-Bind.
8. Testing has been on going (even in summer months) since January 2003.
9. Temperatures are outside air temperatures.
10. * -- * Implies that fans were turned on.
11. NH3 is in ppm.
12. Weekly egg production was recorded as a percentage of 7 eggs/per bird/per week to make sure there was no detrimental effect of feeding BRZ.
13. Starting manure depths were recorded to show the effect of manure versus ammonia levels.
14. The only houses that exceeded 90% egg production were houses 3, 7d, and 7h where there were no or low levels of manure at the start of the test.
15. Operator is under strict reporting requirements by United Egg Producers (UEP)
