Abomasal ulcers affect mature cattle and calves and have several different manifestations. Common clinical signs include anorexia, bruxism, abdominal pain, occult blood in the feces, and tachycardia. Ultrasonography and laboratory tests may aid making a diagnosis. Treatment is based on decreasing acid secretion in the abomasum.

Abomasal ulcers are the most common cause of proximalgastrointestinal hemorrhage in cattle. Another major cause of melena is intussusception. Intussusception may result in an increased PCV, whereas blood loss by ulceration will cause a decreased PCV.

Abomasal disorders include left displaced abomasum, right displaced abomasum, abomasal volvulus, abomasal ulceration, and impaction. Displacement or volvulus occurs most commonly in dairy cows but can also occur in dairy bulls and calves.

Typically, sole ulcers are recognized by protrusion of the corium at the ulcer site. The exposed corium can range from a fresh/red to a brown/necrotic appearance. Sole ulcers typically occur in the lateral hoof of the rear legs because it bears more weight compared to the medial hoof.

Aug 1, 2008 · There has been extensive research into the etiology of abomasal ulcers in cattle. It is well established that nonsteroidal anti-inflammatory drugs alter the mucosal barrier by interfering with local prostaglandin synthesis.

Nov 15, 2013 · As with equine ulcers, lack of roughage can increase gastric emptying and predispose a steer or heifer to ulcers. So how does one know if a cow has an ulcer? With horses, we learned last week that a definitive diagnosis is made with an endoscope to visualize the ulcer.

Sole ulceration is one of the three most common causes of lameness affecting beef and dairy cattle. Sole ulcers occur beneath the flexor tuberosity of P3 (third phalanx). These occur most commonly in the outside digit in rear legs and are associated with varying degrees of changes in weight bearing. How to recognize it?

Abomasal ulcer disease is of great importance in cattle. Abomasal lesions are divided into erosions and ulcers [1]; erosions are superficial lesions of the mucous membrane and ulcers are deep defects that penetrate the basement membrane of the abomasal mucosa [2].

Abomasal ulcers penetrate the basement membrane of the mucosa. Cause: multifactorial - anything that affects abomasal defenses such as trauma, hyperacidity, stress, concurrent disease and NSAID usage. Signs: melena, colic, anemia, sudden drop in milk production. Diagnosis: PCV, fecal occult blood, ultrasound, exploratory laparotomy.
