Abstract

The objective of this study was to find zinc (Zn) concentration in blood and different tissues in Baluchi lambs fed different levels of organic and inorganic sources of this element. Thirty-six male growing lambs with an average weight 26.5±0.3 kg were divided into six groups and fed basal diet (no Zn supplementation, BD), 50 or 100 ppm zinc sulphate monohydrate (Zn-S), zinc proteinate (Zn-P) and their mixture (Zn-P+S, 50 mg/kg each). Results showed that serum Zn concentration was significantly (P<0.05) high in lambs fed 100 mg/kg Zn-P or mixture of Zn-P-S at the rate of 50 mg/kg each. Zn in heart and testis was significantly (P<0.05) high in lambs fed Zn-S (100 mg/kg) and Zn-P-S. In kidney, liver, muscle and spleen, Zn concentration was significantly (P<0.05) high in lambs fed with Zn-P, Zn-S and Zn-P-S. The results showed that Zn fed as organic source at the level of 100 mg/kg or at the rate of 50 mg/kg in combination with ZnSO 4 showed higher bioavailability in serum and tissues.
