Liquid feeding

Liquid feeding systems from SKIOLD make effective feeding advanced without being complicated

We have a number of solutions from a simple standard system with only one mixer to more advanced systems and multiphase systems with several mixers and feeding tanks. 

Principles of Liquid Feeding

Traditional system of norms

The system of norms is understood as the traditional way in which a liquid feeding is installed. The feed remains in the pipe between feedings. In this type of system, the feeding computer can calculate the quantity of the individual components resting both in the mixing tank and in all parts of the pipe system. Thus the system is capable of compensating the various recipes. Depending on the present conditions under which mixing can take place, an optimal feed-mix will be reached. SKIOLD's feeding computer will always inform you exactly what is being fed and by itself adjust for changes in feed-value and contents of liquid.


This principle is an extension of the standard system, but typically consists of two mixing tanks, each holding a recipe. The first recipe is distributed from one mixing tank, and then the contents of the circuit is exchanged with the recipe from the other mixing tank. The feed of the first recipe is now pushed back into the mixing tank, which has just distributed. This type of system is typically used for finishers, where there is a change of recipe in the middle of the growth period.

Residue free liquid feeding

Basically the system consists of mixing tank (liquid feed mixer) and a liquid tank. The liquid tank mixes the amount of liquid, which is needed for the feeding. This amount of liquid is afterwards being pumped through the feed circuit and back to the mixing tank (liquid feed mixer). When the feed distribution is starting, the feed from the mixing tank is pushed into the feed circuit, and the liquid inside the circuit is returning to the liquid tank. When the mixing tank runs empty, the system changes over and starts pumping from the liquid tank, and the distribution of feed continues for as long as feed is left inside the circuit. In this way, only liquid is left inside the feed circuit. Residue free liquid feeding ensures that only freshly made feed is distributed, resulting in a better feed consumption.

Ad-lib liquid feeding

Years of experience with ad-lib feeding has resulted in a unique program with useful functions like for example:

    • Automatic calculation of appetite at different times of the day

    • Automatic calculation of mixing quantity

    • Alarm for lacking appetite at certain valves

    • Choice of requested amount quantity per time per valve

    • Restriction of feed intake per valve

These are all functions that have proven to be useful tools for a successful implementation of the ad-lib system.

Phase feeding

The basic principle in a phase-feeding system is that two separate mixing tanks individually make up a recipe with a high respectively low content of protein. From each mixing tank a separate circuit is leading to the stable(s). The pipes run parallelly over the pens, and through a feed-valve from each pipe these are connected to the drop pipe of each pen. As the two valves open simultaneously it is possible to mix the exact blend of protein, which is adjusted to the growth-phase of the pig. Next to profitability in feed consumption you will experience a considerable reduction in phosphorus and nitrogen of the manure.
