The study aimed to describe the changes in clinical
findings and serum levels of gastrin, pepsinogen and chloride (Cl) in dairy
cattle with displacement of the abomasum (DA) from day 0 until day 30 after
surgery and to evaluate their diagnostic and prognostic value in evaluation of
the abomasal function. The study was conducted on DA cattle (n=25) belonging to
dairy farms in Hokkaido area, Japan. Cows were examined and sampled at days 0
(surgery), 7 and 30. Based on blood β-hydroxybutyric acid (BHBA) at day 0, DA
cows were classified into three categories; DA only (<1.2 mmol/L), DA with
subclinical ketosis (DA SCK: 1.2–2.4
mmol/L) and DA with clinical ketosis (DA CK: ≥2.5 mmol/L). All DA groups had
higher serum gastrin than their physiological reference values in cattle both
before or after surgery. Serum gastrin was significantly increased (p<0.05)
in DA and DA SCK groups particularly at day 30 vs day 0. Serum pepsinogen and
chlorides were not remarkably changed in any of the three diseased groups
compared to reference values. Serum pepsinogen showed no significant within- and
inter-group changes. The surgery and the 30-day follow-up period were not
sufficient to serum gastrin to return to its physiological levels. In
conclusion, further future studies may be required to investigate serum
gastrin levels change in DA cattle. A longer follow up period up to
45 day is suggested.
