Abstract

In pig breeding, selection traditionally takes place based on purebred pig (PB) performance at the nucleus level, while pork production typically makes use of crossbred animals (CB). The success of this selection therefore depends on purebred-crossbred genetic correlation (rpc). The majority of the total production cost of a slaughter pig originates from the growing-finishing phase. There is an increasing trend to give attention to the performance of CB in order to better select PB for CB performance. The current study aimed to estimate rpc for daily gain (DG), back fat thickness (BF) and loin depth (LD), and estimate genetic correlations (rg) between those traits in PB and in three-way CB pigs.
