Chromium is anessential element required for carbohydrate,fat,and protein metabolism in different animal species (Anderson, 1997; McCarty,1991). It has been
demonstrated that Cr is an integral component of chromodulin, acting as a part of the insulin signaling across the
cell membranes and participate in glucose metabolism
(Mertz, 1993; Vincent, 2000). Dietary Cr supplementation
has been shown to positively affect weight gain and feed
conversion in growing poultry(Jackson etal.,2008;
Samanta etal.,2008). Also,animprovement in antibody
