Lohmann Germany has announced that the current application of Respeggt in ovo sexing at the Ankum Hatchery will be extended for an additional three years.
The Respeggt process involves assay of estrogenic hormones in a sample of allantoic fluid extracted from eggs on the 9th day of incubation following the principle developed by Embrex in the late 1980s. The Respeggt process is applicable to both white and brown-feathered strains.
