Table 4 Posterior mean (standard deviation) of the genetic correlation, litter correlation and residual correlation of linoleic acid (C18:2), eicosadienoic acid (C20:2) and arachidonic acid (C20:4), expressed in relative value (mg/g of fatty acid), with body weight (BW), backfat thickness (BT) and intramuscular fat content (IMF)

From: Linoleic acid metabolic pathway allows for an efficient increase of intramuscular fat content in pigs
