Chicken
Feed Additive
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. 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 odour
control in poultry operations. Many farms have eliminated most of
their odour 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.
Benefits
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
Inceased shell thickness
Increase egg production
Reduced foot pad burns from phosphorus
Lowered mortality
Increased nitrogen content of manure and compost.
Egg wash water can be recycled after filtration in zeolite
Using
zeolite found that Leghorn chickens required less food and water
and still gained as much weight in a 2-week trial as birds receiving
a control diet. Feed efficiency values (FEV) were markedly higher
at all levels of zeolite substitution. Feedstuffs containing zeolite
gave rise to efficiencies more than 20 percent greater than those
of normal rations (Table 1). The droppings of groups receiving zeolite
diets contained up to 25 percent less moisture than those of control
groups.
In
addition to a feed-efficiency increase, the presence of zeolite
in the diet appears to have had a favorable effect on the mortality
of the birds.
Tests
were carried out on 48-day-old Leghorns over a 14-day period, 30
birds/group. Normal rations consisted of 16.5% crude Protein and
66% digestible nutrients.
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 aflatoxin.
