Citation Abdul Waheed Ghanghro. Assessment of metals concentrations in dairy feed collected from urban and rural areas dairy farms. AbstractMetals contamination in animal feed is one of the major issues for animal's health and performance because these toxic metals may accumulate in various organs of animal. The present study was aimed to determine the various concentrations of selected metals copper (Cu), Zinc (Zn), Cadmium (Cd), Lead (Pb), Manganese (Mn) and Nickel (Ni) in 60 dairy feed samples collected from urban and rural areas of District Jamshoro Sindh by applying atomic absorption spectrophotometer (AAS). Significantly higher levels of Cu, Zn, Cd, Pb, Mn and Ni were obtained in dairy feeds collected from urban areas of Jamshoro. Mean levels of metals in dairy feeds were in the order of Zn>Cu>Pb>Cd>Mn>Ni and Zn>Cu>Cd>Ni>Pb>Mn in both areas. Significantly negative association for Zn-Cd (r=-o.463), Zn-Mn (r=-0.349) and Zn-Cd (r=-0.361) and Zn-Ni (r=-0.377) positive association for Cd-Mn (r=0.307) and Mn-Ni (r= 0.22) were found in between the concentrations of metals in both areas dairy feed samples. In cluster analysis (CA) metals were grouped in three main clusters indicating their same source of origin.
