The aim of this work was to estimate selection response for performance traits average daily gain (ADG), off-test age (A95) and number of days on test (ND95), to reach 95 kg of live weight, evaluated for Landrace (LD), Large White (LW), and Pietrain (PT) breeds, in a nucleus herd. Breeding values were predicted using mixed model methodology. Estimates of response were determined using Weighted Least Squares method. The estimates were favourable for three breeds and both sex. For ADG these […]
