SUMMARYA total number of 240 laying hens and 24 cocks of Silver Montazah strain at 40 weeks of age were randomly divided into 12 groups (20 hens and 2 cocks / each treatment group). Birds in all treatments were nearly similar in the average initial body weights and average daily egg production A 4 x 3 factorial design experimentwas performed including four levels of supplemented lead (0. 250,500 a...

Every flock in every area of the world may experience, in different levels, the toxicity induced by heavy metals derived from contaminated feed our water sources. Such technical article can undoubtedly be considered as a helpful reference for poultry producers to reduce negative effects expected in such conditions.

A good article about contaminated feed and indicating the efficacy of VIT.E as a potential antioxidant. 
it is also revealed that lead as a contaminant to poultry feed especially in layers is hazardous to human as the meat ,egg .albumen ,liver ,has the potential to absorb these toxic effect ,causing health hazard to humans.

also i wish to know what are the effects on broilers ,and especially the breeders [hatchability % ,embryo deformity ,and subsequent chick performance on farms.]

Thank u dr.ayyat for your useful article. I'm a veternerian and get Msc. degree in poultry diseases. My question dear dr. if there is any toxicity with lead in drinking water of chicken can we treated it with clay or vit. E especialy we know that the bird drink double dose when compard with feed intake and how much we must add to the drinking water for poultry especially brioler breed and how long we must added it?

In this study we used bentonite.
Natural clays are crystalline alumino-silicates characterized by their ably to exchange cations without major changes in structure. Zeolite and bentonite are the most common natural clays wed in animal production. Natural clays can be used as feed binders hi feed manufacturing. Natural clays can adsorb toxic products of digestion and decrease the accumulation of toxic substance in animal tissues, thus decreasing the incidence of internal disorders. Natural clays may stimulate the lining of the intestinal tract that increases the production of antibodies, which could then inhibit the onset of enteritis. Addition of natural clays in animal diets improves growth rate, feed conversion and increases return from body gain and final margin. Nutrient digestibility increases by natural clay supplementation in animal diets, due to its low rate of passage.

Respected Dr.,

Does any Clay based Pellet Binder bind vitamins? My specific query is regarding B Group Vitamins.

Is there any suggested particle size of such clay binders?

Thanks & Sincere Regards

Dear author,
Your target of the experiment is to project how some clay and vitE support contaminated feed on laying hen.
My point is chicken feed should be properly screened before feeding for commercial purpose when layers are in confined rearing program by farmer. In free range rearing birds has selective eating powers.
My worry is what I should remember from such experiment? If i know from test that the feed is contaminated with heavy metal then how it is fed to bird? Unless the feed is free from such heavy metals, toxins, antitoxins then perhaps any additive to remove the impact is a costly proposal. In my opinion let us look to the brighter side of the layers who are to be protected through planning for best nutrition. Nutritionists use bantonite ,vitE all the time as toxin binder and for better resistance power etc.. Pl let me kindly be enlighten on the targets of your experiment? Thank you sir.
