Please tell me alternative method to reduced concentration of heavy metals in poultry feed ?
The levels of any element in animal feed are the result of the levels of those elements in the different constituents used. So the levels of heavy metals in poultry feed depend on the feedstuffs used.
The best approach in my view is to be critical and selective in the feedstuffs used, rather than trying to correct things after the feed is made.
Minerals and animal protein ((including bones) are often a source of heavy metals. So check the individual feedstuffs and select those with low concentrations of heavy metals.

sir C.A. (Kees) Kan thanks alot but my question is that can we made a absorbent materials like a charcoal for water purification.sir give me more suggestions about poultry feed to make absorbent material to removed concentration/contaminations in poultry feeds?
I very much doubt that you will be able to selectively absorb heavy metals, while not at the same time absorbing some of the essential micro elements or vitamins. Therefore my strong advice to concentrate on selecting appropriate feedstuffs and not trying to correct things afterwards. See also my 1994 paper.
