A simple and inexpensive procedure is described for the treatment of copper sulphate supplemented diets for growing pigs, to ensure uniform distribution of the copper in the sample. Water was added to form a slurry and the copper sulphate crystals dissolved. The slurry was mixed and dried to yield a product with uniform distribution of copper. Maximum recovery of copper was achieved by the use of magnesium nitrate as an ashing aid prior to analysis by atomic absorption spectroscopy.
