Changes in serum lecithin: cholesterol acyltransferase and apolipoprotein B-100 in dairy cattle either with 1-7 Days in milk displaced abomasum or with 8-21 Days in milk displaced abomasum

Displacement of the abomasum (DA) is a common and economically important problem of dairy cattle in early lactation. This study described the clinical findings and serum biochemical changes of lecithin:cholesterol acyltransferase (LCAT) and apolipoprotein B-100 (apoB-100) in cows during 1-7 and 8-21 days in milk (DIM) from day 0 before surgery up to day 30 after surgical interference. The study was conducted on DA cattle (n= 24) belonged to dairy farms in the Hokkaido area, Japan. The examined cows were classified based on the onset of DA into two groups: DA (1-7 DIM) group (n=11) and DA (8-21 DIM) group (n=13). Cows were examined and sampled at days 0 (operation), 7 and 30. Dairy cattle in the two DA groups showed significant (P<0.01) elevation of serum LCAT and apoB-100 at days 7 and 30 when comparing with their values at day 0. These significant changes were not reported between the 2 DA groups at any day of sampling. This study concluded the recovery of diseased groups and the significant effect of surgical operation where serum LCAT and apoB-100 returned to their physiological values.
