Abstract

One generation of selection was used to compare two methods of selection: a Multiple Trait Culling Levels (MICL) procedure and a Best Linear Unbiased Prediction (BLUP) procedure based on an animal model. Genetic evaluation involved 14 traits in six White Leghorn strains. There were significant, but small genetic gains for most of the traits selected and some important correlated traits for both procedures. Results of BIIJP and MICL selection differed for four traits: body weight, residual feed consumption, egg specific gravity and Haugh units. These differences appeared to be due to different economic emphasis
