Answers to Patient, Student, and Clinician Questions About How Animals Are Slaughtered and Used for Food.

"Do cattle and other animals know they are walking up a chute that will lead to their death?" Many people ask this question, which the author first had to answer when starting work in the cattle industry. From observations at slaughter plants, feedlots, and ranches, the author learned that cattle behavior was the same when entering a chute for vaccination and when entering a chute for slaughter. If cattle knew they would die, their behavior should have been wilder and more agitated at the slaughter plant, but that was clearly not the case. This article canvasses points of ethical and clinical relevance for discussions about human dietary consumption and practice.
