                                       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.

           1.      The chickens were fed a mash feed containing ½% w/w 14x40 BRZ.
           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 this winter 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)
