Abstract
In Zambia poultry farming is a widely recognized commercial activity. There are both large and small scale farmers utilizing stocks of birds whose parental/grand parental lines were developed and selected mos.t often in the developed countries of the temperate regions. The existence of Genotype x Environmental interactions for traits such as body weight, growth rate and mortality in poultry has long been recognized. It is therefore conceivable that genetic improvements in those traits obtained in temperate regions may not be fully transferred to tropical. And subtropical environments without undertaking special testing programmes, sometimes under simulated environmental conditions. Low correlations of breeding values suggest that a low indirect response may occur if selection is carried out only in one environment-Temperate (Horst, 1985).
