Traumatic reticuloperitonitis (TRP), also known as hardware disease, is caused by the perforation of the reticulum wall by a sharp foreign body, producing acute local peritonitis. Foreign bodies are commonly ingested accidentally through feed or while grazing, as cattle lack oral discrimination and may lick metallic objects. The foreign body can become trapped in the honeycomb structure of the reticulum or penetrate into surrounding areas like the thoracic cavity, liver, or spleen. Clinical signs include fever, reduced appetite, abdominal pain, and reluctance to move appearing 24 hours after penetration. Diagnosis involves history, clinical signs, abdominal fluid analysis, radiography, ultrasound, and metal detection. Treatment options are conservative care with antibiotics

2. TRP
•Perforation of the wall of reticulum by a sharp
foreign body produce ,acute local peritonitis.
Etiology
•Accidental ingestion of foreign body through feed
or while grazing in the pasture.
•Lack of oral discrimination in animal
•Tendency to lick metallic object
•Greedy feeding

3. Pathogenesis
1. Foreign body after ingestion passes to
reticulum and may be entrapped there due to
honey comb appearance of reticulum .
2. Foreign body may pass toward thoracic cavity
causing damage to lungs and heart .
3. It also take different course causing damage
of liver and spleen in abdominal cavity .
Clinical signs commence after 24 hours of
penetration

4. Clinical Pathology
• Leucocytosis , neutrophilia with shift to the left
Clinical finding
• High rise of temperature
• Sudden anorexia
• Ruminal stasis (constipation )
• Local pain in the Abdomen
• Pain on movement ( disinclined to move )
• Recovery may occur if treated
• It may lead to chronic form resulting to acute diffuse
peritonitis

6. Diagnosis
ØHistory
ØClinical finding
ØParecentesis
ØReticular radiography
ØUltrasound
ØUse of metal detector
ØThe diagnosis is difficult since it simulates other
clinical signs especially various forms of
indigestion.

7. The test which have been recommended including
• Reticular grunt test
• Scootch test
• Pole test
• Slope test
• Xiphisterum percussion test

11. Line of Treatment
Conservative treatment
ØImmobilization of the animal
•Front feet elevation
•Reduction of roughage feed
•Administration of antibiotics
ØSurgical Treatment
Ø•Rumenotomy
•Repair and post surgical measure

14. Prevention
Prevention measures include
üavoiding the use of baling wire
ü passing feed over magnets to remove metallic objects
ü keeping cattle away from sites of new construction
ü completely removing old buildings and fences.
üAdditionally, bar magnets may be administered PO, preferably
after fasting for 18 magnets remains in the reticulum and holds
any ferromagnetic objects on its surface.
üThere is good evidence that giving magnets to all herd
replacement heifers and bulls at 1 yrears of age minimizes the
incidence of traumatic reticuloperitonitis
