The experiment was conducted by sheep , and the diet was treated by F and I ,high F containing High-Fluorine Aquatic Weed was digestible F ,and I was added the form of KIO3. (F:50,100,150mg/kg I:25,50,75mg/kg), Through digesting experiment , feeding experiment and slaughter experiment ,we studied the effect of diet F and I on digestion of nutrient ,hormones and tissues uptabe of F and I .The results were showed as follows:1.The group adding 50mg/kg F and 25mg/kg I appeared the best digested energy and metabolic energy When adding 100mg/kg F and 25mg/kg I, N digestion/metabolism was the best ,when adding 50mg/kg F and 75mg/kg I, it appeared of that absorbtion of F was the highest attended to 59.83mg/kg and absorbtion of I was the lowest attended to 23.52mg/kg.2.The group of adding 50mg/kg F and 75mg/kg I appeared lower T3 level compared with other groups and adding 150mg/kg F and 50mg/kg I appeared the lowest TSH level. The diet F and I did not effect the sheep T4 level significantly . The diet F and I did not effect the sheep AKP,T-AOC level significantly(P>0.05).3.When the diet was added 50mg/kg I and different levels of F .The results showed the deposition of F in kidney was the lowest in the control , compared with other treatments. Kidney F and heart F of group 1 was the highest (P<0.05) .The body F deposition reduced when added 50mg/kg and 150mg/kg F, the animal did not appeared toxic phenomenon.The teeth F of group 2 was the highest (P<0.05). The rib F of treatments was similar , the rib ,tibia Ca and rib, tibia P was lower than the control .The weight of sheep in group 2 ,group 3 increased.4.The digestion of nutrients was the highest (P<0.05), when adding 10mg/kg F and 50-75mg/kg I, and F deposotion in bone (P<0.05) and kidney (P<0.05), of the group adding 100mg/kg F was the highest by slaughter. However ,the sheep did not appeared toxic phenonmena ,also daily growth was significant.The results mentioned indicated that the diet was suitable by adding 00mg/kg F and 50mg/kg I in sheep production.5. By slaughter experiment, except teeth was sensitivity apparatus of reflecting fluorosis.Firstly ,we found the heart was harmed easyly. In this experiment, change trend which fluorine content of...
