Danish Experiments with Copper for Bacon Pigs0 kg. This will also ensure a lower copper content in the pig manure. There was a tendency towards a slight increase in the iodine value of the backfat, when the diet was supplemented with copperj but otherwise no influence was observed on carcass quality.

These findings indicated that the Fergus sludge toxicity to crops probably was due to Cu. A large build up of Cu in the roots of annual ryegrass grown on soil treated with Fergus sludge was further evidence for Cu toxicity.

A great amount of research endeavour followed throughout the world and established beyond any reasonable doubt that an addition of 200 – 250 mg Cu/kg diet results in increasing the profitability of pig keeping, without having any known

Growth rate stimulation from 8 to 9.7% and increasing feed efficiency by 5.5 to 7.9% (Braude et al., 1962; Braude, 1967) have been demonstrated. Experiments using up to 207 ppm of Cu in the feed given as CuSO. conclude that the gr
