Liquid feeding systems for sows, weaned pigs, and finishers

Extended by the connection of a special control computer, this system setup is a reliable and successful form of modern swine management.

The Big Dutchman WetMIX liquid feeding systems are all computer- controlled, individually assembled and programmed for each swine house. All system parts, such as silo screw conveyors, weighers, pumps, feed mixing vats and all feed valves are therefore matched to each other and optimally coordinated according to the swine yield required.

Different feed mixes are made up per feeding for various animal groups. This phase feeding enables the animals to be given the correct quantity and composition of feed according to their age. Depending on the system version either water, feed or air will remain in the pipes after feeding. All systems are extendable and can be upgraded as required.

Everything depends on the mix

Dosing of feed components into the mixing tank is monitored by the computer. For mixing, the components flow into the feed mixing tank, the mixing ratio of the mixes being freely selectable. Any feed or rinsing water remaining from the previous feeding is taken into account in the following mixing process (residual quantity management). The mixing tank and the intermediate tank can be provided with cleaning equipment.


A weighing bar is fitted below each mixing tank foot. It checks the changes in weight in the feed mixing tank water remaining from the previous feeding is taken into account in the following mixing process (residual quantity management). The mixing tank and the inter- mediate tank can be provided with cleaning equipment.

The stonetrap

The stonetrap contains adjustable tines and magnets so that almost all metallic and nonmetallic objects can be removed from the feed. Regular cleaning increases the efficiency of the stonetrap.

The PSI-feed valve

The PSI-feed valve has been developed in order to enable feeding of smallest quantities. Air pressure allows the valve to close in a quiet manner instead of snapping shut. The absolute silent dosing of liquid feed is most beneficial in sow barns.

Sensors for the feed trough

The BIOCONTROL sensors in the feed trough record the time, animals need to clean up their trough. The recorded time affects the following feed quantity to be dispensed. They are the »eyes of the barn manager« and make frequent manual adjustments of the feed quantity unnecessary.


Feeding more often, approx. 6 to 12 times a day
Varying the feed quantity at the respective feeding times depending on how fast the animals eat up their feed.

A large number of factors, such as barn temperature, humidity, state of health, etc. influence a pig’s appetite and thus its speed of feed intake.

Utilization of growth potential

Animal appetite tends to vary during the day and in the course of longer time periods. Feed intake and the growth potential of the animal’s will be fully utilized.

Feed intake plan

According to the eating times, which are entered in the »feed intake plan« of the program, the animals will either receive a feed bonus or a deduction in the next feeding cycle.


The TopCLean cleaning system offers a simple and professional solution of regular cleaning of mixing tanks. With the help of air pressure, an acid or alkali cleaning solvent is sprayed or »fogged« into the mixing tank. Additional nozzles allow water rinsing after fogging.

The medicator

The medicator works parallel with the first feed valve. Via a separate pipe a special liquid (vitamins or medicine with water) can be injected into the feed flow. This avoids that mixtures of feed and special liquids get to places in the feeding system where they are not desired.

The medicator, consisting of mixing tank, agitator, pump and valves, is available in a mobile and a stationary model. It is operated by the feeding computer and connected to a separate pipe.
