Iron Excess And Laminitis

Digestive upsets due to grain overload such as excess grain fruit or snacks or abrupt changes in diet.

Iron excess and laminitis.

Dietary iron is thought by some to contribute to the incidence of laminitis in horses with serum ferritin starting to be used as the measure of iron status. Iron overload symptoms in horses include coat changes of bleaching and red ends on dark manes and tails often hoof issues such as laminitis and abscessing. Iron deficiency anemia is rare and too much iron can potentially lead to laminitis as well as create an imbalance with other minerals. Excess iron is a much greater concern in horses because free iron ions fe2 act as oxidants causing damage to dna cell membranes and other structures.

Dan pitzen a water expert in ohio published a report several years ago titled. In clue like fashion i m declaring the cause of my six horses laminitis over the last 18 years as an excess intake of iron from weeds trace mineral blocks and well water leading to insulin resistance and the insulin form of laminitis. When anaemia is suspected blood should be looked at under the microscope and a cbc red and white blood cell count done and correctly interpreted to verify whether the horse. Furthermore forages pasture hay hay pellets or cubes are already high in iron making supplementation unnecessary and possibly dangerous.

These include coat changes of bleaching and red ends on dark manes and tails often hoof issues such as laminitis and abscessing. Uncommon contributors to ems and subsequent hyperinsulinemia are iron overload and ovarian abnormalities in some mares. High levels of iron intake have also been associated with insulin resistance and laminitis in horses. Iron is toxic to the liver hepatotoxic and vets have reported that excessive iron deposition in the liver is a common finding in liver biopsies from older horses.

Some laminitis problems in horses may be caused by excessive iron intake it appears to have been published in 2006 that s the date the word document online was created though i m not sure. I nerida don t know if this is the case but in reading human literature it seems the relationship between serum ferritin and inflammation is a bit of a case of chicken or the egg. This study linked iron status to insulin resistance ir in horses. It is estimated that 80 percent of all laminitis cases are due to endocrine dysfunction specifically excess insulin in the blood.

The causes vary and may include the following.
