Abstract

Abomasal ulcers are common in cattle, especially in calves, and to date, there is no reliable antemortem method for diagnosis, to our knowledge. We assessed if measuring sucrose in blood after oral administration in calves could be used to identify animals with abomasal ulcers. Terminally ill calves (n = 12; part A) and calves designated for slaughter (n = 123; part B) were given a sucrose solution per os, and blood samples were taken 15, 30, 60, 90, and 120 min (part A) or 30 and 60 min (part B) after administration. The calves were then euthanized or slaughtered, and their abomasa were examined. Serum samples were analyzed using highperformance liquid chromatography-mass spectrometry, and data were analyzed using general linear mixed models. Calves both with and without affected abomasa had increasing sucrose values over time without significant differences. Also, there was no relationship between the size of the mucosal lesion and sucrose values.
