was able to re-use data on individual cow
experiments dating back nearly 100 years.
Data on growth and body composition of in-
dividual broilers (Håkansson et al ., 1978a,b)
were also used by Emmans (1994) and for
many other useful developments in model-
ling. Some system of posting detailed infor-
mation as appendices to papers or as
spreadsheets on the internet could make a
considerable contribution to the develop-
ment of poultry models.
The exchange of models or parts of
models could also play an important part
in encouraging research with shared
goals. The technicalities of programming
and support on different platforms may
limit such exchange but it remains a
worthwhile objective. In overviewing the
work that has been published it is appar-
ent that much that has been achieved has
probably been lost to future developers
and users.
