At Jansberg farm, technical results of weaning piglets can be followed.


Farrowing area Tom Janssen, however, takes an optimistic approach. Besides the gestating sow house, the piglet area was reconstructed in 2019 and his next plan involves a reconstruction of the cur- rent lactation house. Currently it houses 120 sows, and as the buildings are rather outdated, they will be demolished in the course of 2020. The first step in this process is to ensure cur- rent capacity can be maintained – a capacity upgrade is pos- sible but not yet planned. Janssen says, “These buildings will also be one open space; again, that’s what I prefer. We also took into account that in the future it might become law that sows will have to be loose during most of lactation. I’m pret- ty sure it will head that way – perhaps not in the next 10 years, but it will come. If that turns out to be true, we can easily convert to those new requirements.” Currently he weans 30 piglets/sow/year – due to more space being available for the piglets in the new farrowing and lac- tation house as from late 2020, Janssen expects that figure to go up.


A clever way of adding extra space in the farm: a pen on a second floor.


Upbeat about the future One way of going that extra mile is that for several years, his farm has also been a trial farm for Joosten Young Animal Products, including products developed to reduce antibiotics usage (see also box). The company mostly produces high quality feed for piglets. The products obviously need to be tested and tried often under commercial conditions so there will be plenty of documented experience about their efficacy before they hit the market. The testing in the weaner buildings, which were renewed in 2019, involves various rounds of weighing. Janssen says, “It is usually quite a lot of extra work, as we would normally do that roughly five times per production round. Typically I will place most piglets apart and then weigh them one by one. What is helpful is that each piglet has a radio-frequency iden- tification (RFID) tag in their ear, so data can easily be stored.” These tests are usually blind, he says, that is he does not know which batches get the feed with Joosten products in- cluded and which get the control feed. Positive or negative results for him are impossible to gauge, he says. “That is usu- ally a matter of 50g or so, which is impossible to see with the naked eye. The only thing that one sometimes can see is fae- ces quality. When the feed is highly digestible, you’ll see that there is not a lot of diarrhoea occurring.”

Antibiotics usage The RFID also plays a role in another future-proof project: Jansberg is participating in the Westfort slaughterhouse’s scheme to market antibiotic-free meat. As such, the farm is trying to get by without the usage of antibiotics. Seeing that the farm produces its own breeding stock, the disease pressure is relatively low. Antibiotics are only used on an in- dividual basis, Janssen says. “We may treat an individual pig
