Abomasal impaction of cattle in Saskatchewan

Area of Science:

• Veterinary Pathology
• Animal Science
• Gastroenterology

Background:

• Abomasal impaction is a significant gastrointestinal condition in cattle.
• Previous studies suggest dietary and traumatic origins for this condition.

Purpose of the Study:

• To investigate the causes and characteristics of abomasal impaction in cattle.
• To differentiate between dietary and traumatic forms of abomasal impaction.

Main Methods:

• Retrospective review of 75 necropsy reports from cattle diagnosed with abomasal impaction.
• Analysis of lesion types, suspected causes (dietary vs. traumatic), and clinical presentation.

Main Results:

• 60% of cases were attributed to dietary factors (excessive fiber), 20% to traumatic reticuloperitonitis, and 20% to other causes.
• Abomasal tears, ulcers, and necrosis were observed in nearly half of the cases.
• Dietary impaction was more prevalent in beef cattle, while traumatic impaction was more common in dairy cattle, often linked to dry, fibrous feeds.

Conclusions:

• Abomasal impaction in cattle has distinct dietary and traumatic etiologies.
• Dietary management and prevention of traumatic reticuloperitonitis are crucial for reducing incidence.
