    Abstract: Mineral contents in the soil and forage are spatially distributed. 
  Pasture fenced has created nutrition imbalance problems for animals. As a result, 
  Semi-Fine Wool sheep are affected by a disease characterized by emaciation, 
  lameness, stiffness in the gait, enlargement of the costochondral junctions 
  and abnormal curvature in the long bones. The objective of this study was to 
  determine possible relationships between the disease and pasture fenced. Results 
  showed that Phosphorus (P) concentrations in forage samples from fenced areas 
  were significantly lower than those from without fenced areas and the mean Calcium 
  (Ca):P ratio in forage in fenced pasture was 11:1. Meanwhile, P concentrations 
  of blood, bone, teeth and wool from fenced sheep were also significantly lower 
  than those from without fenced group. Serum p levels of animals in fenced pasture 
  were much lower than those of without fenced ones whereas serum alkaline phosphatase 
  levels from fenced animals were significantly higher than those from the without 
  fencing group. The disease could be alleviating with supplement of Disodium 
  Hydrogen Phosphate (Na<SUB>2</SUB>HPO<SUB>4</SUB>) or demolish fence on pasture. 
  The study clearly demonstrated that the disease of Semi-Fine Wool sheep was 
  the P deficiency in forage mainly caused by pasture fenced.
