All 315 cases were in females. Amongst breeds the highest incidence of left abomasal displacement was in Holstein (82.9%) followed by Jersey (9.8%) cows. Nearly 56% of all cases were 4-6 years old (mean 5 years). Over 69% cases occurred between January and June. 97.5% cows were lactating and 91% were less than 6 weeks post-partum. The history was associated with other diseases including milk fever (12.4%), ketosis (42%), metritis (41%) and retained placenta (30%). Concurrent disease conditions included metritis (43.5%) and mastitis (19%). Right flank laparotomy revealed liver adhesions in 8% and peritonitis in 7.4% of cases. Of 312 surgically treated cows, 33 died; 10 had recurrence. Post-operative treatment often included systemic administration of sugar solutions and antibiotics. The most common post-operative complication was mastitis (7%). Casual factors are discussed.
