Summary: | The objective of this study is to investigate effect of air cleaner operated
during pig breeding period on stress hormones of pigs and their pork quality.
The stress hormones (cortisol, epinephrine and norepinephrine) in blood sample
of pigs reared in the housing rooms with or without air cleaner have been
measured according to a pig’s rearing stage: 0 day (farrowing), 21st day
(farrowing–weaning), 70th day (weaning–nursery), 140th day
(nursery–growing), and 180th day (growing–fattening). The
comparison of pork quality according to the application of an air cleaner was
performed through the carcass analysis of the pigs shipped from swine house. The
levels of cortisol, epinephrine, and norepinephrine in pigs reared in housing
rooms with and without air cleaners were found to be within the range of normal
reference values. Among pork quality evaluation items, the thickness of
intermuscular fat and final carcass grade of pigs raised in housing room with
air cleaner was generally superior to those of pigs raised in housing room
without air cleaner (
p
< 0.05). Based on the results
obtained from this study, it is concluded that air cleaner does not have a
significant effect on reducing pig stress but contributes to improving pork
quality in pig breeding. |
