Residual-free liquid feeding of pigs
Increase in piglet weight at weaning by up to 1.2 kg | Medicine consumption reduced by 50%

ACO FUNKI offers a high quality residual-free liquid feeding system, which is the advanced technology and efficient investment. In this system, potable water is used as a pressure source, and provides pipes irrigation.

In traditional systems residues of a food are staying in the pipes between feedings, which leads to the decomposition and neutralization of amino acids and proteins, which are important to the pig’s health.

Residual-free feeding eliminates the decomposition of amino acids, because the system is rinsed with water after each feeding. In addition, residual-free feeding can save about 40% of the energy due to the fact that there is no need to collect the food from previous feeding back into the mixing tank and to use the energy to the secondary mix - all residues are washed with water.

Residual-free liquid feeding is a feeding method that ensures no leftovers in the feed pipes after feeding. This ensures fresh feed for each feeding, and not a mixture of new and old feed.

Benefits of the residual-free liquid feeding:

  • Increased number of weaned piglets with approx. 3 per sow per year
  • Increase in piglet weight by weaning up to 1.2 kg
  • Medicine consumption reduced by 50%
  • No loss of amino acids
  • Return on investment: 1-1.5 years


The mixing tank has the mixture ready. The tank for residual water is empty. The tank for clean water is full and there is clean water in the pipe line.


The mixing tank is emptied. The tank for residual water is filled. When there is no longer feed in the mixing tank, the water is pumped from the clean water tank. In this way, the clean water tank is used to distribute the feed left in the feed pipes, and when the last valve has been fed, the feed pipes are filled with water.


The mixing tank is empty. The residual water tank is filled up.
