Summary

Abomasal ulcers were found in 20.5% of 912 cows. These bovine ulcerative lesions, classified by severity, could not be diagnosed using blood or rumen chemistry.

Area of Science:

  • Veterinary Pathology
  • Bovine Medicine

Background:

  • Abomasal ulcers are a significant concern in cattle health.
  • Understanding the prevalence and characteristics of these lesions is crucial for diagnosis and management.

Purpose of the Study:

  • To investigate the prevalence and types of abomasal ulcers in a cattle population.
  • To assess the correlation between abomasal ulcers and haematological/biochemical parameters.

Main Methods:

  • Macroscopic and histological examination of 912 abomasa from a local slaughterhouse.
  • Analysis of haematological, blood chemistry (urea, AST, K, Cl, Ca), and rumen chloride concentrations.

Main Results:

  • Abomasal ulcerative lesions were present in 20.5% of examined cattle.
  • Ulcers were classified as Type 1 (erosions/non-perforating), with subtypes 1a-1d based on severity and morphology.
  • Specific subtypes (1a/1c, 1b/1d) showed regional predilection (pyloric/fundic regions).
  • No significant correlation was found between abomasal ulcers and the evaluated biochemical or haematological parameters.

Conclusions:

  • Abomasal ulcers are relatively common in this cattle population.
  • Current haematological and blood/rumen chemistry analyses are insufficient for diagnosing Type 1 abomasal ulcers.
  • Further research may be needed to identify reliable diagnostic markers.
