This study evaluates heavy metals in selected broiler feed using anon-destructive analytical technique. In this study four feeds commonly used in feeding Nigerian broilers were sampled from different areas of Kaduna State, Nigeria. The results shows that all the concentrations or mass fraction of essential trace metals Ca, K, Cl, Mg, and Na were present in significant amount, respectively; while the heavy metals Fe, Mn, Zn, Rb were also present in all the samples respectively, the remaining were below detection limit (BDL).The results obtained were within the WHO recommended values of 45-80 ppm, with Fe and Zn concentrations in BRC and BRD samples exceeding the WHO/FAO maximum acceptable limit of 45-80 ppm and 10-50 ppm as adopted by SON.
