At the two breeding stations for poultry Middelfart and Strynø having a capacity for 6.000 laying hens and 24.000 broiler chickens respectively I had the possibility to run genetic experiments using a part of the capacity for these purpose and then running the developing of new lines for the poultry breeders in the residual of the capacity during the years 1973 to 1995. This research capacity was used to perform selection experiments and a scientific based development of new breeding methods. After closing the breeding stations in 1992 due to the concentration of breeding companies  and the  stop of Danish  there were established facilities at Research Center Foulum that made it possible to run breeding experiments some of the activities was continued .
