Electrical anaesthesia of male
embryos in the egg with STUNNY

In scientific studies it was proven that embryonic reactions associated with possible awareness of pain were absent in 99.3% of the examined embryos after perfusion with 110 Volt over two seconds (ZUMBRINK et al., 2020*). On this basis the high-throughput machine STUNNY was developed and evaluated in collaboration with the German Training and Consultancy Institute for animal welfare at transport and slaughter (bsi Schwarzenbek).

The fully automated STUNNY anaesthesia unit is adjacent to the output of male embryos from the CHEGGY unit. Inside the STUNNY, the male embryos are anesthetized by electric current flow to eliminate any possible pain sensation for the embryos at the interruption of development.
