Abstract

Growth rate (ADG) and back fat (BF) data were collected during five generations of selection in two lines of Gene Pool pigs (14-breed synthetic): select (S) and control (C). C were randomly selected, while mass selection was practiced in the S line with an index (I), I = 100 + 286.6 (ADG) - 39.4 (BF). S and C pigs were fed a 14% protein, corn-soybean meal diet from 42 d of age until they reached 79.4 kg.
