Project Details:
The aim of the project is to transfer an innovative concept for cold-storage of liquid preserved boar semen into practise. This enables the reduction of antibiotics in the preservation medium and additionally, the optimization of the transport logistics of the semen portions from semen collection centers to the sow farms. The environmental impact resulting from antibiotic use is reduced and possibilities for efficient use of boar semen are tested in practice. Thus, the CoolSperm project particularly promotes sustainability and efficiency in future-oriented pig breeding.

Project Details:
The goal of this project is to reduce the environmental pollution caused by the entry of antibiotics and resistant bacteria from pig breeding. Worldwide, antibiotics are added to liquid preserved semen portions in order to inhibit bacterial growth during semen storage.The present study aims to establish an innovative concept to eliminate bacteria without using conventional antibiotics. The concept is based on the photodynamic inactivation (PDI) of bacteria. Specifically, the aim is to inactivate microorganisms in boar semen using the photodynamic effect and, thus, to avoid bacterial growth and
exchange of resistance genes in the environment.
