Guizhou 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 mineral deficiencies. Samples of tissue and blood were collected from affected and unaffected sheep. Samples of soil and forage were collected from affected and unaffected areas. The samples were used for biochemical analyses and mineral nutrient measurements. Results showed that phosphorus (P) concentrations in forage samples from affected areas were significantly lower than those from unaffected areas ( P < 0.01) and the mean ratio of calcium (Ca) to P in the affected forage was 12:1. Meanwhile, P concentrations of blood, bone, tooth, and wool from the affected sheep were also significantly lower than those from the unaffected group (P < 0.01). Serum P levels of the affected animals were much lower than those of the unaffected ones, whereas serum alkaline phosphatase levels from the affected were significantly higher than those from the unaffected (P < 0.01). Inorganic P levels of the affected sheep were about half of those in the control group. Oral administration of disodium hydrogen phosphate prevented and cured the disease. The study clearly demonstrated that the disease of Guizhou semi-fine wool sheep was mainly caused by the P deficiency in forage, as a result of fenced pasture and animal habitat fragmentation. © 2014 Shen et al.

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 (Na2HPO4) 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. © Medwell Journals, 2013.
