Growth rate and feed conversion in lines of pigs selected for rate of gain and thickness of backfat
Acta Agriculturae Scandinavica 24(4): 309-318
Data on daily gain and feed conversion of 5627 pigs from 783 litters used in a selection experiment based on daily gain and backfat thickness were analysed. During 5 generations, pigs were selected for high rate of gain and low backfat thickness (HP) or for low rate of gain and high backfat thickness (LP). A 3rd line was kept as controls (CL).In all 3 lines, a 1st-degree regression was found for the effect of weaning weight on post-weaning daily gain.
