These objects settle in the reticulum (a part of the cow\u2019s stomach) and may puncture its lining, leading to infection or damage to nearby organs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the University of Missouri Extension, <strong>55\u201375% of cattle<\/strong> in some regions have ingested metal.
