Abstract

Abomasal ulcers lead to several problems. They cause pain resulting in a decrease in productivity and even the possible loss of the animal. Because they are frequently difficult to diagnose, information on their prevalence is variable. Additionally, therapeutic options are limited. Abomasal ulcers are graded as type 1 through 4, type 1 being a superficial defect and type 2 an ulcer where a large blood vessel has been eroded, leading to substantial blood loss. Types 3 and 4 are perforated abomasal ulcers leading to local and diffuse peritonitis, respectively. Causes of abomasal ulcers are multifactorial, for example, mistakes in feeding that lead to gastrointestinal disturbances or other diseases that induce stress. Ulcers can also result from side effects of nonsteroidal anti-inflammatory drugs. In principal, the pathophysiological cause is the disturbance of the balance between protective and aggressive mechanisms at the abomasal mucosa due to stress. Clinical symptoms vary and are mostly non-specific. Fecal occult blood tests, hematology and blood chemistry as well as ultrasonographic examination and abdominocentesis can help to establish the diagnosis. Ulcers can be treated symptomatically, surgically and medically. To prevent abomasal ulcers, animals should be kept healthy by providing adequate nutrition and housing as well as early and effective medical care. Stressful management practices, including transport and commingling, should be avoided.
