AB  - Bactrian camels in Haizi, Gansu China are affected by an ailment 
  characterized by pica, emaciation, dyskinesia, deprived appetites and anemia. 
  Researchers found that concentrations of Cu in soil and forage from affected 
  areas and unaffected areas were similar and within the normal ranges but the 
  concentrations of S in soil and forage were significantly higher (p<0.01) 
  in affected than in unaffected areas. Concentrations of Cu in blood, hair and 
  liver from the affected camels were significantly lower (p<0.01) than those 
  in unaffected camels. Fifty affected Bactrian camels grazed on affected pastures 
  consumed an average of 136 mg of Cu/day for 60 days by a free-choice, salt-based 
  trace mineral supplement. Average liver Cu concentration was 37.9±5.5 
  &#956;g g<SUP>-1</SUP> at the end of the study. On the 62nd day, ten Bactrian 
  camels were removed from the affected pastures and allocated to one of two treatments 
  for 80 days, consisting of supplement providing 125 mg day<SUP>-1</SUP> of either 
  Cu sulfate or Availa-Cu. Liver Cu increased over time in all camels regardless 
  of treatment, however, camels supplemented with Availa-Cu have higher mean liver 
  Cu contents than those receiving Cu sulfate (163.6&plusmn;13.5 and 228.9&plusmn;26.7 
  &#956;g g<SUP>-1</SUP> for Cu sulfate and Availa-Cu, respectively) at the end 
  of the study. Mean Cu content in the liver of Bactrian camels received Availa-Cu 
  was significantly higher than that in supplemented camels with Cu sulfate. Thus, 
  it is reasonable to conclude that ailments of Bactrian camels in the Haizi area 
  are caused by a secondary Cu deficiency mainly due to high sulfur content in 
  soil and forage.
