Project seeks to produce pig with  optimised phosphorus utilisation and higher bone stability

The Research Institute for Farm Animal Biology — together with Swiss company SUISAG, which offers genetics for successful pig farming, and medical technology company PoroUS GmbH — is launching the project, "Improved phosphorus utilization and increased bone stability in pigs" (PigBoneS).

The aim of the project is to select and breed pigs with optimised phosphorus utilisation and simultaneously increased bone stability. The latter is made possible by the non-invasive POROUS 3D ultrasound method, which ensures the precise measurement of bone density and stability. The identification of relevant genetic markers forms the basis for a new advanced breeding programme targeted at achieving significant progress in animal health and the environmental impact of animal husbandry.

The project has many positive implications: Optimised phosphorus utilisation can lead to better bone development and stability, which promotes the general well-being and growth of the animals. The POROUS method provides an important diagnostic basis for assessing bone health.

"We are very happy to start this project with two strong innovative partners. For POROUS, the project offers the opportunity to expand the scope of our technology," said Julia Eschenbrenner of POROUS. "We look forward to making a contribution to animal welfare and environmental protection."

Kay Raum's Imaging, Simulation and Stimulation group at Charité Universitätsmedizin Berlin is also involved in carrying out microstructure analyses and numerical sound propagation simulations in bone. The approach to improving pig health also effectively addresses the problem of leg weakness in fast-growing animals in modern housing systems.

Additionally, more efficient phosphorus utilisation reduces phosphorus excretion via manure and thus mitigates the environmental impact of animal husbandry. This emphasises that nutrient efficiency, environmental protection, and sustainable farming practices are linked. By focusing on improving phosphorus utilisation, pig producers can work towards more environmentally friendly and sustainable food production.

The Research Institute for Farm Animal Biology's project was approved as part of the Eureka Eurostars network programme and started on June 1. The network program promotes cross-border innovation projects and is supported and funded by the BMBF in Germany and Innosuisse in Switzerland.
