Abomasitis
Abomasitis (abomasal bloat) is a relatively rare ruminant disease characterized by inflammation of abomasum in young calves, lambs, and goat kids. It occurs with gastroenteritis but is seldom diagnosed as a separate condition, and its causes are as yet unknown. Its fatality rate is uncertain but appears to be 75 to 100%.
