during each step of the marketing

“We’re trying to gam insights on

and handling procedures that
could minimize such stress,” says
Mayes.
Mayes’ work is part of a larger
research project at the University

“We’re studying weight losses
associated with handling and

Mayes says.
Mayes obtained heart rate data
on pigs in about a dozen activities.
The heart rate of sleeping pigs
usually ranges between 100 and 160

Pigs experience reduced blood
flow when their hearts beat more
than 210 times per minute.
“This results in something
similar to heart attack in
humans,” says Mayes, “slowing
blood flow to extremites and
raising body temperature.”
Pigs that are pressured into
prolonged physical exertion could
collapse. But the 35- to 85-pound
