Abstract
Fluoride is a naturally occurring element, fluoride compounds are
constituents of minerals in rocks, soils, air, natural waters and foods. In the
other way aluminum the most abundant metal in the Earth’s crust, is present
in a variety of foodstuffs and medications (e.g. vaccines and antiacids) as
well as in domestic water supplies. Aluminum compounds form less soluble
complexes with fluoride and decrease the absorbability of fluoride or
neutralize the hydrogen fluoride produced in the stomach.
The present work was performed to study the effect of sodium
fluoride and aluminum sulphate on clinical signs, growth performance,
hematological and biochemical changes and correlate them with
pathological changes in balady chickens. In addition to the evaluation of aluminum sulphate as a treatment of sodium fluoride toxicity.
This study was carried out on one hundred and fifty (one day old)
balady chickens. Chickens were divided into six equal groups (each group of
25 chickens); first one fed on normal ration (control group); second one fed
on ration contains 800 ppm of sodium fluoride; third one fed on ration
contains 1600 ppm of sodium fluoride; fourth one fed on ration contains 640
ppm aluminum sulphate; fifth one fed on ration contains 800 ppm(sodium
fluoride)+ 640 ppm (aluminum sulphate) as (1st treated group) and sixth one
fed on ration contains 1600 ppm (sodium fluoride)+ 1280 ppm (aluminum
sulphate) as (2nd treated group) from one day old to the end of experiment
(seven weeks).
