Copper Effect in Feed Supplementation on Growth Performance in Young Pigs
Keywords:
copper supplementation, growth performance, young pigsAbstract
In this study we aimed to follow the effect of copper supplementation from different sources and levels on growth performance and feed conversion mode, at young pigs. The research was done on 45 animals (young pigs) that were divided in 3 variants: V1=6 mg Cu/kg feed (CuSO4+5 H2O); V2=31.25 mg Cu/kg feed (CuSO4+5 H2O); V3=31.25 mg Cu/kg feed (Cu-polyphosphate glass source). The duration of the trial was 60 days. In the growth period the average daily gain was significantly increased (p≤0.05) to V2 (369 g/day) and V3 (394 g/day) comparative with V1 (321 g/day). Feed conversion ratio was significantly lower to V2 (2.54 kg) and V3 (2.37 kg) than V1 (2.81 kg). Copper supplementation at 31.25 mg Cu/kg feed (V3) resulted in an increase in average daily gain up to 22.7% and feed conversion ratio was reduced to 18.6%, compared to the control group.
