Organic hogs typically grow slower
and are less efficient than conventional
hogs. Differences in management may
account for some of this.
• The Rosmanns worked with ISU swine
specialists to implement three levels of
feeder management (once-weekly and
twice-daily adjustment, and hand-fed).
• Hogs under once-weekly and twicedaily
adjustment had similar growth
and production parameters, with a
slight advantage to twice-daily.
• Twice-daily adjustment resulted in
slightly better feed efficiencies than
hogs under once-weekly adjustment.
However it required more labor.
• Adjusting feeders more frequently
provides some feed cost savings and
improves the efficiency of gain in
finishing organic hogs.
