Short term response to selection in layer type chicken: direct and correlated responses to selection for egg production to 280 days



Short term response to selection in layer type chicken: direct and correlated responses to selection for egg production to 280 days



Journal of Sustainable Agriculture and the Environment 3(2): 361-364



Direct and correlated responses to selection over 5 years (1991-1995) were evaluated using a population of layer-type chickens bred and managed at the National Animal Production Research Institute, Ahmadu Bello University, Shika, Zaria, Nigeria. A control population raised alongside the selection population was used to evaluate the genetic response. The genotypic response was 3.14 eggs per year while the phenotypic response was 1.61 eggs.
