Science (ASAS) in Denver July
27-Aug. 1, Wendy Powers, an
ISU assistant professor of ani
mal science, outlined a feeding
trial that studied the effects of
bloodmeal in swine rations on
manure composition and odor.
Bloodmeal is a common ingredi
ent in swine feed.
Fifteen five-week-old pigs
were fed for each of two, four
week periods. The rations
included either 3 percent blood
meal, 1.5 percent bloodmeal or
no bloodmeal. The pigs were
housed separately depending on
their ration, and manure was
cleaned from each room once
each week.
Manure and air samples were
collected twice weekly, on days
four and six, for the last three
weeks of each feeding period.
Manure samples were sent to a
commercial laboratory for com
positional analysis. Air samples
were analyzed by a trained
human panel and by an elec
tronic nose, which is a machine
designed to measure odors.
Powers said she found a
strong trend for increased odor
as the amount of bloodmeal was
increased in the hogs’ diets.
Odor also increased as the
length of time the manure was
stored increased from four to six
days. No performance differ
ences were found with any of the
feeding regimens.
The project was conducted in
late 1997. Powers plans to
repeat the feeding trials this
year. “We’ve shown odor intensi
ty increases with greater
amounts of bloodmeal in swine
rations. This means we might
someday be able to make dietary
recommendations to reduce odor
potential,” she said.
Beyond studying the impact
of bloodmeal on manure odor,
Powers said she also wanted to
compare the two methods of
measuring odor intensity the
electronic nose versus a human
panel. “The electronic nose did
not mimic the results of the
human panel as well as we’d
hoped,” Powers said. “On the
other hand, the human panel
showed wide daily variation in
treatment response where the
electric nose was more consis
tent.”
Powers said the results show
more work is needed to “train”
the electronic nose to better
match human noses. “When
testing odors, the human panel
ranks the odor and the electron
ic nose is trained to accept this
ranking. But this showed the
electronic nose does not always
accurately reflect what a human
smells. Since humans can be
influenced by psychological fac
tors and instruments can’t, this
may account for differing results
between the two methods.
Also at the ASA meeting,
Powers presented a seminar on
the steps producers can take to
control odors “We’re putting
together a number of strategies
that are cost-acceptable for con
trolling downwind odor,” she
said Powers discussed odor con
trol measures that included
dietary manipulation and hous
ing alternatives, plus storage
and land application of manure
Many of the strategies
Powers outlined are being tested
on private lowa farms as part of
the state’s odor control demon
stration project.
