Suggestions to Derive Maximum Stocking Densities for Layer Pullets

摘要

Simple SummaryThe housing of farm animals, such as laying hens and broiler chickens, is regulated by the European Union (EU). However, for young laying hens which are not laying eggs yet, i.e., so-called pullets, no regulation for the number of birds per space is available. We exemplarily calculated maximum stocking densities for pullets based on their body size taking into account the European regulations for adult laying hens and broiler chickens. Our approach is mainly considering that a certain proportion of additional space should be provided to enable the birds to perform active behaviour.
