A Comparison of the Efficacy of Proprietary Products in the Treatment of Molybdenum Induced Copper Deficiency

Conclusions

Over the 10-week duration of the trial, the bolus gave the best maintenance of copper status and correction of clinical copper deficiency by preventing uptake of free tetrathiomolybdate into the sheep. The needles and injection also corrected the clinical copper deficiency, with the injection increasing the plasma copper and caeruloplasmin more, whilst the needles were better when the CP/PlCu ratio and TCA insoluble copper were assessed. The chelate was better than the drench for copper status although neither could sustain the correction of the clinical deficiency.
