ABSTRACT
The study was conducted to analyze three different tissues (liver, gizzard and muscle tissue) of the broiler chicken for absorption of four heavy metal contents (Cu, Zn, Pb and Ni). In addition, analysis of five electrolytes (Ca, Na, K, P and Mg), moisture content, protein, lipids and ash were carried out. The samples were obtained from five different sites of the University Campus, Peshawar- Pakistan. The Atomic Absorption Spectrometry was employed for determination of Cu, Zn, Pb, Ni, Ca and Mg. Furthermore, a spectrophotometer was also used for the purpose of phosphorus (P). However, the analysis of sodium (Na) and potassium (K) content was done through a flame photometer. It was observed that gizzard had the highest concentration of Zn (24.84mg/kg), Pb (2.25mg/kg) and Ni (2.34mg/kg) while, had lowest concentration of Cu (3.30mg/kg) Ca (8.05mg/kg) Na (74.29mg/kg), P (130.67mg/kg) and Mg (15.85mg/kg). Liver had highest concentration of Cu (7.74mg/kg) and Mg (24.23mg/kg) while lowest concentration of Pb (1.24mg/kg) Ni (0.64mg/kg), K (205.20mg/kg) and Na (74.32mg/kg). The muscle tissue come up with highest concentration of Ca, K, Na, P and Mg were 18.65mg/kg, 258.13mg/kg, 110.59mg/kg, 455.53mg/kg and 27.06mg/kg respectively, whereas lowest concentration of Zn (13.13mg/kg). It is concluded that muscle tissue of the broiler chicken is comparatively a good source of macro-nutrients (Protein, Lipid) and micro-nutrients (Ca, K, Na, P and Mg) and less contaminated with heavy metals.
