FARM VISIT ▶▶▶ Future-proof feeding sources

Two of the future-proof products that re- cently went for trials at the Jansberg farm were JPC 56 and FMR Ω3, developed by Joosten Young Animal Nutrition. In 2019 tri- als by Illinois University in the US, these die- tary ingredients scored exceptionally well in digestibility trials involving cannulated pig- lets – the products achieved scores of 98.9% and 96.3% respectively, meaning that the products’ amino acids are virtually com- pletely digested before it reaches the colon. That in turn means that there is hardly any substrate for pathogenic gut bacteria to feed on any undigested proteins in the co- lon – hence the need for gut-health con- trolling mechanisms like antibiotics is

strongly reduced.The vegetable protein products are being produced in a special- ised Dutch manufacturing site dedicated to feeds and ingredients for young animals, a good hour’s drive away from Castenray, the farm’s location. For production, different vegetable protein ingredients are used such as soy, wheat gluten, pea and potato pro- teins. In order to reach these high digestibil- ity values, it is imperative that the locally sourced ingredients are always fresh and of superior quality, explains Wim Beeks, man- ager of sales and marketing with Joosten. Once inside the facility, they are finely ground to a particle size of 200 microns. The particle size is also an explanation for the

high digestibility of these protein sources, adds his colleague Lars Gorisse, technical manager at Joosten. He says, “That means that the anti-nutritional factors also natural- ly present in some raw ingredients, like for instance β-conglycinin in soy, are also ground to very small particles. In that size, the piglet’s gastrointestinal tract can better deal with them.” The other natural components glutamine and omega-3 fatty acids in the formulated products have, in combination with the high amino acid digestibility, shown to improve feed conversion ratio, manure quality, sur- vival rate and uniformity in many university and piglet field trials.

for a cough or a sow for lameness. Then we will fill that out in the system that corresponds to the animal’s ear tag, so at the slaughterhouse they will know which ones to process differently.”

Manure treatment Last but not least, outside the farm there is a huge manure separation truck installed, pumping up the manure from the pits and separating it into liquid and solid parts. Janssen says, “The liquid part is being spread out on the land nearby, but the solid part is sold off.” He grins: “It’s the black gold.”

Electronic Sow Feeding The farm visit ends where it began, as the mandatory show- ers are next to the gestation area. In that room, full of quiet- ly sleeping sows, Janssen opted for dynamic groups with Electronic Sow Feeding stations by Nedap. He is happy hav- ing made that choice, given that the gestating sow house is

peaceful and does not require a lot of manual work. The ani- mals are fed rations from 3pm each afternoon, with the amounts depending on their stage of gestation, up to a maxi- mum of 2.8kg per visit. Should the ear tag reveal that the sow has already eaten, then the system can simply send her out again. Janssen says, “My personal touch to all this is that I have created a circuit through the pig house. Sows have to walk all the way around to get back to the entrance of the feeding stations. So dominant sows tend not to come back to the feeding station immediately.” Anyway, sows usually choose to wait their turn. Pointing up, Janssen says, “The other day we threw a party in the farm of- fice, which is right up there, with windows looking out over the gestation area. Even later at night we could still observe sows going in to get their share of feed. When you check their daily feeding behaviour, you can see a pattern. It’s not like they feed at 10pm one day, and the next day in the after- noon. They always like to feed at the same time of the day.”
