This research was conducted to evaluate the effect of different zinc (Zn) sources on performance, bloodmineral and cell counts of Zandi lambs. 18 male lambs at weaning were supplemented with two differentsources of zinc, 25 ppm ZnSO4 and 25 ppm zinc-peptide added to the basal diet as control. Live bodyweight, weight gain and feed efficiency improved with Zn-peptide supplementation (P<0.05). Sera Znconcentration was higher and copper and iron concentration was lower in zinc supplemented groups(P<0.05). Supplementation of zinc had no effect on blood cell counts except for white blood cells thatdecreased with zinc peptide supplementation (P<0.05). It was concluded that adding 25 ppm zinc peptideto fattening lamb diet improved performance and cause to higher level of blood zinc.
