PEF system for liquid feeding

High-voltage pulses make the entire maize plant digestible for pigs

The German Nutrition Society (Deutsche Gesellschaft für Ernährung, DGE) states that food rich in crude fibre is indispensable for personal health and well-being. This not only applies to humans, but to pigs as well. An entirely new process now makes the important roughage in the fibres of the full maize plant digestible for pigs. Feeding maize can reduce costs and improve the land use as well as animal health. The innovation was awarded a gold medal by an international expert commission of the “DLG” (German Agricultural Society) prior to EuroTier 2014. 

Big Dutchman, the German market leader for livestock technology, has further developed PEF processing for daily use in pig houses. Scientific support was provided by the German Institute of Food Technologies (DIL) in Quakenbrück. The Big Dutchman PEF system applies high-voltage electric pulses to a mixture of water and maize. The system is installed between a pre-mixer and the liquid feeding tank. The pulses change the cell membranes of the crude fibres, an essential step to make these nutritional components digestible. The pigs’ gastrointestinal tract is affected positively.

In addition, the cell disruption of the feed energy components ensures successful finishing of healthier pigs and reduces costs. An extensive study at the teaching and testing centre of the Chamber of Agriculture Schleswig-Holstein in Futterkamp has shown impressive results which prove these positive effects.

Initially, the system was tested with maize plants. However, it seems that it can be applied to other feedstuffs as well. The food industry is already using PEF processing to treat fruit juices and products made from potatoes successfully and without using chemicals.

The high-voltage pulses break the closed cell structures of enzymes in a way that the food is easier on the gastrointestinal tract, an advantage that is also beneficial to animals. The increased crude fibre share affects the pigs’ health positively, therefore making it possible to reduce the use of medication. Another positive effect: The available agricultural areas can be used more efficiently as the entire maize plant serves as nutrient, instead of only the cob.

New agitator for liquid feeding

With the current state of the technology, solid and liquid feed components are only mixed ideally at a specific filling level in the mixing tanks of liquid feeding systems for pigs. The reason: The agitator blades are fixed to the drive shaft. At EuroTier 2014, Big Dutchman can now present a level-controlled agitator which automatically adjusts its position to the filling level in the mixing tank. This allows the pig manager for the first time ever to mix different feed quantities ideally in the same tank – with the mixture constantly remaining homogeneous. The quality of the feed is improved and operating costs are reduced. Prior to the show the Big Dutchman innovation was awarded a silver medal by an international expert commission of the “DLG” (German Agricultural Society). 

A float guarantees that the agitator is always in the ideal position for mixing, depending on the filling level. Spinning agitator blades not even immersed in feed are a thing of the past, just like blades which are so low in the liquid that a homogeneous mixing of the components is not possible.

The result is a recipe whose ingredients are mixed perfectly at nearly every filling level. Furthermore, the tanks remain cleaner because very little liquid hits the walls. The improved hygiene in the tanks reduces efforts required for cleaning.

Farmers who have to feed groups of different sizes or pigs of different ages will particularly benefit from the new, level-controlled agitator. It can be retrofitted into existing Big Dutchman liquid feeding systems.

SwapTank system for liquid feeding

With the SwapTank system, Big Dutchman introduces at EuroTier 2014 a true innovation for the residue-free liquid feeding of pigs. The exceptionally variable system allows the exact mixing and dispensing of very small as well as very large feed quantities. Its highlight: There is no need for a separate rinse water tank! 

Instead, two tanks of different sizes are sufficient. Both can be used either as mixing tank or as rinse water tank, depending on the presently required amount of feed. This is made possible by a new and unique control function of the Big Dutchman HydroMix liquid feeding computer. The new system reduces investment costs and improves accuracy as well as hygiene during feeding.

SwapTank is not only of interest to pig managers with large numbers of stock whose demand for feed increases significantly over time and which have to be supplied with feed optimally and without delay. It particularly has many advantages if the feed demands are very different, for example in mixed production systems with sows and piglets or piglets and finishing pigs, or in closed systems.

If the animals have to be supplied with a large quantity of feed, the Big Dutchman control computer selects the larger tank as mixing tank, while the smaller one functions as rinse water tank. Whenever smaller quantities are sufficient, the smaller tank is used as mixing tank and the rinse water is fed into the large tank and taken from there.

As the tanks are selected as necessary according to circumstances, the feed is mixed homogeneously and dispensed very accurately. Tank size and the requested feed quantity always match perfectly. The tanks are also emptied regularly, another factor which improves hygiene.

TwinSpin tube for liquid feeding

The longer the tube, the more important the mixing. This applies especially to tubes used to transport liquid feed to pigs. Big Dutchman can now present a tube system with an integrated spiral which – according to scientific evidence – transports the ideally mixed feed gruel to the trough with a quality as of yet unknown. This is an important factor for being successful in pig breeding and finishing. 

Practical experience shows that on its way to the feeding place, recently mixed liquid feed often separates and forms deposits. This particularly happens in very long tubes and results in feed of different composition reaching the pigs. Tubes and valves are in danger of becoming clogged and hygiene problems are inevitable. The company Big Dutchman, in cooperation with the laboratory for fluid dynamics and turbomachinery of the University of Applied Sciences Osnabrück, therefore developed a mixing tube which keeps pressure and mixture constant even over longer distances.

The ground-breaking characteristics of the Big Dutchman “TwinSpin” system are underlined by a recent analysis of the University of Applied Sciences. The double spiral tube system is head and shoulders above the previous Big Dutchman system and most of the products on the market. Its secret is the geometry of the two internal ridges, the so-called double spiral. This spiral is responsible for constantly mixing the gruel without tapering the tube. The result: optimum mixing and perfect hygiene.

“There was a lot of fiddling involved, but it was worth it in the end,” states Ralf Garberding, head of the Development department at Big Dutchman Pig Equipment GmbH. He knows that a hygienic portion of feed which can be measured accurately is an important factor for success. His conclusion: “TwinSpin is a true quality leap in liquid feeding.”

Small, compact and cleverly connected: Big Dutchman introduces a robust innovation to read electronic sow ear tags at the EuroTier 2014. BestReader registers the sow number and transfers it wirelessly and quickly to smartphones and tablets via Bluetooth. The BigFarmNet app, which is available for the established operating systems Android and iOS, connects the transponder number and the corresponding animal data. The farm manager is thus always up-to-date in his sow house, whether he is online or offline. It is easily possible to use several end devices. 

Compared to similar readers, BestReader is very small and light. It is hardly larger than a pack of cigarettes, only weighs 126 g and will not break, even when dropped from a height of up to two meters.

The reader is equipped with a power button and a button to activate the reading process. The battery is charged by an inductive charger and lasts for approximately one week. As the reader requires absolutely no plug contacts, ingress protection rating IP 69 applies. This is official proof that the reader is not sensitive, and is protected against dust and watertight.

The BigFarmNet app synchronises the transferred data automatically and in real time with the BigFarmNet management program on the office PC. No manual synchronisation via cable is necessary thanks to the wireless network or GSM. The management program is based on the innovative BigFarmNet technology which is able to interconnect the entire farm. All applications and control computers belong to one single program.
