| The expertiment has been conducted on the animal field that is attached to the department of animal resources,College of Agriculture –University of Diyala, and lasted 56 day 180 fingerlings fish of Cyprinus carpio L.Fish were distributed randomly into 18 equarium (30×30×60cm liter of water ). Sex treatments were used each with three replicates with 10 fish. The treatment included adding zinc sulphate at the levels of control, 15, 20, 25, 30 and 35 mg/kg feed. The statistical analysis revealed that treatments 3,4 and 5 showed significant improvement in daily growth rate (0.11, 0.199 and 0.197)gm/fish/day respectively , specific growth rate (0.93, 0.82 and 0.81 respectively). Relative growth rate (65.25, 56.4 and 55.9 respectively), protein rate (1.26, 1.04 and 1.10%) feed rate (28.48, 25.82 and 25.57%) and significant decrease feed conversion rate (3.91, 3.919 and 3.91 respectively. | ||
