Both multi-trait and multi-age selection are thus important
ways of resolving apparent conflicts between breeding goals.
The idea that breeding for high welfare in broilers and
breeders inevitably involves selecting for slower juvenile
growth rate and is on a collision course with efficient
production, therefore needs to be challenged by breeding
programmes with a wider range of strategies than have been
adopted up to now. In the next section we outline some
possible strategies that might help to achieve these goals.
