Laminitis - AKA: Acidosis-Laminitis; Lameness; Founder
Description: laminitis occurs when the blood vessels in the tissue of the hoof become inflamed and dilate. It can be caused by environmental and/or dietary factors. In dietary cases, if a) VFA production exceeds absorption, b) if rumen pH falls below 5.5, or c) if the blood vessels become inflamed due to a blood poisoning, the bone inside the hoof will swell. Because the hoof cannot expand, but the bone can, a cow can experience intense pain from this situation. Laminitis can be either Clinical or Subclinical; subclinical will be less serious but occur over a months-long period. Clinical laminitis will be severe and will occur abruptly,usually because of grain overload. Grain-overload usually also causes acidosis; as such acidosis and laminitis can be linked in some cases depending on the cause.
Prevention: same as rumen acidosis; also additions of zinc and copper to the diet can help, as deficiencies in these minerals can also cause lameness. Finally, the B Vitamin Biotin can work as a preventative measure.
