Chronic fluorine is toxic call fluorine disease again, it is a kind of when absorb the inorganic fluoride that exceeds safe set limit to for a long time to cause continuously toxic disease that gives priority to disease with bone tine pathological changes, it is a deer some closer year come relatively a kind of disease that often produces. Besides long-term and drinkable tall fluorine water, raise feeds the grazing feed that is infected with inorganic fluorine outside, because contain the be caused by of additive of mineral sex feed of inorganic fluorine,commonner is, with fluorine spot tooth, bone fragile disease, float hyperplasia of go to live in the household of one's in-laws on getting married of the bone that send a gender is clinical feature even.
[Pathogeny] : Natural ingredient is like geographical condition, basically be drought, semiarid saline land and low sunken region namely, fluoride enters system with feed through watering inside ceaseless save up and make the deer comes on. It is the factory discharges fluorine to cause big fluorine to pollute an area next, but because water, be grown feed and air to cause Lu Man a bit by fluorine pollution time the gender is toxic. Still have more those who see is additive of mineral sex feed, be like calcium hydrophosphate kind, because contain fluorine,the quantity exceeds mark to be able to bring about fluorine of Lu Man sex toxic happening.
The growth of pilose antler and calcium kind closely related corporeal supply, once calcium is captured by the fluorine of the save up inside body, criterion not only pilose antler grows slow, and make a deer very sensitive to fluoride. Say every kilogram weight commonly of 1 milligram fluorine absorbing an amount is highest and safe limit, exceed this limit, classics 3-4 the month can appear fluorine is toxic symptom.
[Pathology change] : Fluorine is toxic surface of rib sufferring from a deer is lacklustre, color is ashen, rib is out of shape, see dated sex fracture more, the bag outside its with go to live in the household of one's in-laws on getting married of annular and proliferous bone, coarse and rough, break end to be replaced for proliferous bone go to live in the household of one's in-laws on getting married, this paragraphs of costal bone is loose point to pressure namely flat, the hand is broken rupture namely, section is divided show completely almost outside the brim fungous. Rib and union of costal region cartilage are in, visible spadger egg comes columbine egg is big outside crude character go to live in the household of one's in-laws on getting married. It is all round bone length a canal, be in the majority with two side especially, also the amount differs, the bone go to live in the household of one's in-laws on getting married with differ size is generated. Some ill deer have bone gain a son-in-law in such a manner in ministry of pilose antler root, also ossification of some cartilage of ill deer ear, submit the nodal form with irregular, inhomogenous density. Mandible bone sees alveolar fistula, rupture even, local strut is out of shape, serious effect is collected feed.
