Copper Effect of Feed Supplementation on Growth Performance in Fattening Pigs

Tiberiu Polen

Abstract


The research was done on 45 animals (fattening pigs) that were divided in 3 variants: V1 = 6 mg Cu / kg fooder; V2 = 31.25 mg Cu / kg fooder (CuSO4 + 5 H2O); V3 = 31.25 mg Cu / kg fooder (Cu - polyphosphate glass source). The duration of trial was 90 days. In the growth period the average daily gain was significantly upper (p≤0.05) to V2 (773 g/ day) and V3 (811 g / day) comparative with V1 (721 g / day). fooder conversion ration was significantly lower to V2 (3.95 kg) and V3 (3.77 kg) than V1 (4.12 kg).
