Animal-human interaction comparing live human observation and digital image evaluation methodologies

Abstract

base proximities were closer (P < 0.008) in the "look" category compared to CV-PCVM and saline treatments post-injection. Snout proximities of pigs classified in the "look" category were farther (P < 0.05) from the human observer in the CV-PCVM compared to CF/MF and saline treated pigs post-injection. The treatment effects yielded more negative or lethargic behaviors in the CV-PCVM group compared to CF/MF and saline. Future work should focus on determining the behavioral effects from each portion of the vaccination process.

Swine feed efficiency: implications for swine behavior, physiology and welfare

“…In swine production, humans may have little interaction with pigs other than situations that may be perceived as negative by the pig. These situations can include medically treating (Weimer, 2012), castrating, tail docking, restraining, and sorting pigs (Waiblinger et al, 2006). With little opportunity to habituate, it is suggested that even domesticated animals may often perceive humans as predators (Suarez and Gallup, 1982).…”
