In this project, we study if lowering the stocking density during rearing and/or laying has a positive effect on broiler breeder mating behaviour, and thus also on skin and feather damage in the hens.
It is foreseen that there will be a ban on mutilations from 01-09-2011 onwards. To keep broiler breeders without mutliations, there is a need to develop housing or management systems that minimise damaging mating behaviour in broiler breeders.
Expected result: to know if lowering the stocking density has a positive effect on damaging mating behaviour in broiler breeders (december 2010).
Products: two scientific publications (drafts available december 2010) and two publications in the popular press (december 2010).
