The Respeggt technology makes it possible to distinguish between female and male hatching eggs on around the ninth day of incubation. In-ovo sexing technology is applied by Respeggt before day twelve of the incubation as this day marks the possible beginning of pain perception by the chick embryo.
A study by TU Munich from 2023 shows that after day 12 of incubation, different processes in the embryo, e.g., brain activity, are starting. This indicates the beginning of a possible pain perception by the embryo.
Practicing in-ovo sexing before day 12 of incubation guarantees ethical benefits and meets consumer expectations. In-ovo sexing should always be applied as early as possible.
Respeggts‘ in-ovo sexing technology is one of the earliest methods, operating around day 9 of the incubation (see yellow area in the graph).
Respeggt’s goal is to offer even earlier technical solutions through continued research and development.
Stopping the incubation process of male hatching eggs is rapid and effective. In addition, these eggs can be used as high-quality feed and thus play an important role in the circular approach to nutrition.
With using Respeggt technology operating around day 9 of the incubation, we offer an ethical solution „Free of Chick Culling“!
