Abstract: Guizhou semi-fine wool sheep has affected by forage of high molybdenum in the Hezhang County of Guizhou Province in South West China Karst Mountain area. The mineral composition of forage and samples of blood, liver and hair from Guizhou semi-fine wool sheep in affected ranches were compared with those from unaffected areas. Concentration of molybdenum in forage from affected pasture was significantly higher than that from unaffected pasture. The mean concentration of sulfur in forage from affected and unaffected pasture was similar. Mean concentrations of sulfur in blood, liver and hair from the affected Guizhou semi-fine wool sheep were significantly lower than those from the unaffected animals while the content of molybdenum in blood, liver and wool from the affected Guizhou semi-fine wool sheep was significantly higher than that in the unaffected animal. Oral administration of calcium sulfate prevented sulfur deficiency. Researchers concluded that S deficiency in Guizhou semi-fine wool sheep in this area was probably caused by high molybdenum in forage.
