Fattening Pigs

The present study was conducted to investigate the effect of dietary copper supplementation on the growth performance, nutrient digestibility and copper metabolism in fattening pigs. A total of 24 pigs (Landrace X Large White X Duroc) with an average initial BW of 30±1.05 kg, the pigs were divided into four treatment groups, with three replicates per treatment and two pigs per replicate, in accordance with a completely randomized design based on the BW. The results indicated that dietary copper supplementation increased the growth performance, CP and EE digestibility. However, there was no significant increase in the DM and OM digestibility. In addition, copper deposition increased with the increase in dietary copper supplementation, while copper absorption, increased with the decrease in dietary copper levels. In conclusion, fattening pigs with 30-60 kg BW can utilize 45-135 mg/kg Cu and porkers at BW of 60-120 kg can also utilize 10-45 mg/kg Cu as CuSO4 for an increased copper utilization and a decreased in copper deposition.
