Labour saving Tool when practicing Split Suckling

The Split-Suckling Unit releases piglets automatically

You lock the first-born and the biggest piglets away the first 24 hours after birth during 30 to 50 minutes, when you practice split suckling. The last-born and the weak now have the milk bar for themselves and get colostrum.

The split-suckling unit opens automatically up, so all piglets can go to the sow. You do not have to go back to the pen and remove the barrier, and you do not forget to come back. You have halved the visits to the pen, which is positive for avoiding contamination.

You need 15 units for each 1000 sows.

You modify your barrier boards making a hole 160 mm tall and 140 mm wide. Fix the unit with the four bolts, so its hole aligns the hole in the board.


Turn the split-suckling unit ON, adjust the delay time, close the hatch, and position the board so the piglets are blocked. Sort the piglets so the last born and weak stay outside.

According to Danish Seges, the entire top pig producer practise split suckling. See below why this is the case.

Application 1

A newborn piglet gets 80 % of its immune system from the colostrum of the sow. Piglets must have minimum 300 ml colostrum during the first 24 hours. The dispersion among a litter of piglets is big. Scientists have recorded the volume of colostrum suckled by each piglets and for 48 different sows. From the illustration below you see the average lies between 300 and 600 ml.

However, the next illustration shows how many piglets with less than 300 ml colostrum. In average, it is four piglets in each litter, who get a bad start and have a much bigger risk of dying later or be slow to reach the final weight.




Application 2

When a sow gets many and small piglets it is beneficial to heat and dry them, before they practise suckling. Close the hatch, pull them inside and set the time delay to 10-15 minutes. They will come out heated and dry and have more energy finding the teats.

Application 3

The last feeding of the sow can be at the time, when staff goes home, because you can block the piglets and automatically release them 40 to 60 minutes later, when the sow is lying again. This take away the risk of crushed piglets, when the sow lies down.

Application 4

In systems with free sows in farrowing, it is imperative that the piglets rest in the creep area from day one. You separate the piglets from the sow after suckling and let the piglets free after one hour. You may have to do this many times depending on the piglets’ ability to learn. The split-suckling unit saves half the work as it automatically releases the piglets and you are never too late.

Important knowledge

New research shows that the small piglets are not less developed, not premature, as you would think, on the contrary. The will do well if you can give them a good start. In addition, the increase in number of live born piglets does not indicate an increase in mortality. The illustration below shows litter size at the X-axis and mortality at the Y-axis for many Danish farms. The illustration shows clearly that the extra live born piglets has not caused an increase in mortality percentage.

However, the better producers have 1.7 live piglet more, which works out to be € 135 extra per sow and year. So half a million € more profit per year for a farm with 3700 sows.


The split-suckling unit is battery operated so no wires in the pen. You may charge it with an old fashion battery charger for cars or a power supply 19 to 24 Volt. Charging is recommended every second month. When the battery is low, you cannot read nor set the delay time. If battery goes low during delay time, the hatch opens before the battery is dead.

It is easy to use. Press the ON button, read delay time at the display. Adjust the delay using the plus or minus buttons. Close the hatch.
