Evaluation of Motility Hormones in Dairy Cattle with Omasal Impaction and Caecal Dilatation

The aim of this study was to evaluate the motility hormones levels in cattle with caecal dilatation (CD) and omasal impaction (OI). In this study, four cows with OI, four cows with CD (without volvulus) and ten healthy controls were used. Serum ghrelin, motilin, gastrin and leptin concentrations were determined using ELISA. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) activities and sodium (Na), potassium (K) and chloride (Cl) concentrations were measured using a spectrophotometer. Serum ALT, AST and GGT activities were higher in OI cows. Serum Cl concentrations were lower in OI cows than in CD cows. Higher gastrin and motilin levels in OI and lower leptin levels in CD cows were found. In conclusion, this study dose not supports the use of GI motility hormones agonists in cows suffering from omasal impaction and caecal dilatation. Leptin might be indicated in negative energy balance.
