Introduction - Abomasal impaction is rarely encountered in cattle and is characterized by the drying of the abomasal content and the enlargement of the abomasum as a result of the abnormal accumulation of solid matter in the organ.
Aim - This manuscript aims at reporting the occurrence of the rarely encountered abomasal impaction in Turkey. Materials and methods - Two five-year-old dairy cows presenting with symptoms of inappetence, lethargy and constipation constituted the material of the study. Based on the clinical symptoms and necropsy findings, the animals were diagnosed with abomasal impaction.
Result and discussion - The body temperature, heart rate and respiratory frequency of the animals, which were slightly dehydrated, were within the normal ranges. Abdominal auscultation revealed reduced rumen contractions and bowel sounds were not heard. On palpation of the right abdominal wall, a large and hard mass was detected, while percussion was associated with a moaning sound. Post-mortem examination revealed the presence of a blood-tinged, dry abomasal content of hard consistency, composed of roughage and foreign substances, including soil, sand and gravel.
Conclusion - In animals given feed and water containing mud or sand, sand may accumulate in the abomasum and lead to fatal impaction cases, resulting in significant economic losses. Animals displaying signs of chronic weight loss, ruminal tympany and constipation are recommended to be evaluated for abomasal impaction.
