addition to the much
improved trough hygiene, the producer
can also profi t from an improved feed
intake of his pigs as he is now able to
always provide the right amount of
fresh liquid feed in small portions," the
spokesman told Pig International. The
device also determined the feeding
speed during every meal and
automatically processed and displayed
the data so any abnormal deviations in
the pigs' feed intake that could indicate
health issues could be
detected more easily, he added.
The system is based on the principle
of pneumatic filling level measurement.
With this type of measurement, slightly
pressurized air is blown through the
sensor tube directly on to the liquid feed
in the trough. The sensor is installed at
about two to three millimeters above
the bottom of the trough. If the pressure
of the supplied air is higher than the
counter-pressure in the trough, there
is still feed in the trough. The counter
pressure therefore is the measure
determining the filling level.
Animal welfare, monitoring
Also at EuroTier, a Dutch
company specializing in
developing automation processes
for livestock farms was offering
what it described as "complete
solutions for pig husbandry."
A spokesman for Nedap explained
that its computer-based Nedap Platform
allowed individual animal welfare and
monitoring Velos systems to operate
effectively on the basis of electronic
animal identification. This included pig
performance testing equipment, which
Award-winning pig equipment innovations
A mobile weighing system for fattening pigs that works using 3-D camera
technology won the gold medal for innovation at this year's EuroTier event
in Hanover Germany.
The new optiSCAN unit developed by Hölscher + Leuschner in Germany is
described as a handy unit that is held over the fattening pig for three seconds
at a distance regulated by the camera itself depending on the pig body. With
the 3-D picture and certain coordinates it is possible to determine the weight
of the fattening pig digitally, so the strenuous and time-consuming weighing
of the fattening pigs is no longer necessary, explained a spokesman.
The judges said optiSCAN improves labor management and does not
cause any additional stress to the fattening pigs. The device allows more
precise, weight-related marketing and faster and more animal-kindly
Among the silver medal winners were Big Dutchman for its new Sow
Check oestrus detection system that identifies sows on heat in groups with
a feeding station; and BigFarmNet, which worked with Big Dutchman to
develop "Health Monitoring," a software tool that serves to support health
monitoring of pigs kept in groups via demand feeding stations. The software
documents the sequence of visits and feeding times of individual sows in
group keeping on one day and over relatively long periods. Assessment of
the daily events is carried out with regard to the entire group.

Other silver medals went to Landwirtschaftskammer for its Düsser
Rooting Tower, WEDA for its Boar Stub system and Lührs Gerätebau GmbH,
for the "Ringelpietz" Circulating Feeding System.
The rooting tower is an addition to existing occupational and
enrichment equipment for swine. The tower is a device to keep large groups
occupied, for offering variable fibrous rooting or playing materials such
as straw, hay or silage.
Weda developed a retrofit set for the control of system types M 16 and
4 PX for liquid pig feeding systems that work with stub lines. This makes
it possible to feed different mixtures one after the other via a stub line
as of a live weight of 55 kg and makes it possible to administer different
feed mixes for sows and boars in one compartment to exploit optimal feed
conversion of the two genders housed separately.
Lührs developed a system for single-pipe dry feeding installations
that allows different mixtures to be administered in one compartment.
By installing corner drives that have been developed by the company, the
chain can run both clockwise and counter-clockwise. A short wait follows
after feeding, before the chain is emptied by running it in the opposite
direction and a new mixture is then fed to the other gender.
Both innovations can be retrofitted at low cost and satisfy today's
