“…While studies on direct handling (without feeding mediation) have led to mixed results (Heird, Whitaker, Bell, Ramsey, & Lokey, 1986;Mal, McCall, Cummins, & Newland, 1994;Hemsworth, Price, & Borgwardt, 1996), some experiments show that subtle human interactions such as a mere visual contact may have beneficial effects in cattle (Le Neindre et al, 1994), red deers (Pollard, Littlejohn, & Webster, 1994), pigs (Hemsworth, Barnett, & Hansen, 1986), goats (Lyons, Price, & Moberg, 1988), and horses (Henry, Hemery, Richard, & Hausberger, 2005;Sondergaard & Halekoh, 2003). Le Neindre et al (1994) and Pollard et al (1994) even reported that repeated visual contacts with humans were more effective than active handling procedures in cattle and red deers.…”
