Influence of level of copper supplement and removal of supplemental copper from the diet on the performance of growing-finishing pigs and accumulation of copper in the liver



Influence of level of copper supplement and removal of supplemental copper from the diet on the performance of growing-finishing pigs and accumulation of copper in the liver



Canadian Journal of Animal Science 53(1): 133-138



The first experiment was with 44 crossbred gilts of 13.5 kg liveweight in 11 groups. The basal diet had 12 mg Cu/kg and was given alone to 4 groups and with CuSO4 to supply 250 mg Cu/kg to 4 groups. On each diet groups were killed at 23, 46, 69 or 92 kg. The remaining groups had Cu up to 23, 46 or 69 kg and were all killed at 92 kg. There was no significant difference among groups in average daily gain though extra Cu in the last phase tended to reduce gain.
