− | Following surgical correction of an uncomplicated displacement success rates can reach 95%. Abomasomal volvulus and the presence of an abomasal ulcer are associated with a much poorer prognosis. Additionally tachycardia, decreased temperature, black faeces and a long period of illness are all associated with poorer outcomes. | + | Following surgical correction of an uncomplicated displacement, short term survival rates can reach 95%.
