Due to their unselective feeding habits, cattle may injest a variety of foreign bodies. Heavier metallic objects consumed can become lodged in the [[The Reticulum - Anatomy & Physiology|reticulum]], and may penetrate the reticular wall under the influence of the continuous [[The Reticulum - Anatomy & Physiology#Ruminoreticular contraction|reticular movements]].  

Due to their unselective feeding habits, cattle may injest a variety of foreign bodies. Heavier metallic objects consumed can become lodged in the [[The Reticulum - Anatomy & Physiology|reticulum]], and may penetrate the reticular wall under the influence of the continuous [[The Reticulum - Anatomy & Physiology#Ruminoreticular contraction|reticular movements]]. This is enhanced in pregnancy and parturition.

 

Pathological changes depend on the direction of penetration; this is usually in an anterior-ventral direction. Pyogenic bacteria escape from the [[The Reticulum - Anatomy & Physiology|reticulum]], causing localised peritonitis, local fibrinous adhesions
