Research Project: Pain Management in Swine

Location: Livestock Behavior Research

Project Number: 5020-32000-013-49-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 24, 2018
End Date: Sep 30, 2019

Objective:
The objective of this study is to identify management methods to better access the degree of painful procedures so that alternatives can be evaluated.

Approach:
Will evaluate several novel methods of measuring stress when pigs are subjected to different procedures. Piglets are routinely castrated, ear notched, and tail docked; which are known to be painful. We will evaluate if measures of heart rate variability, such as detrended fluctuation analysis, approximate entropy, and sample entropy are useful measures of pain. The piglet’s behavior and physiology will be monitored to determine if alternative methods are able to better detect pain and enhance piglet welfare and decrease subsequent culling due to complications from the procedure.
