Analysis of the causal structure of traits involved in sow lactation feed efficiency

Table 7 Posterior means of genetic correlations and 95% highest posterior density (HPD_95%) intervals among traits based on the multiple trait animal model (MTAM) and on the structural equation model (SEM)

MTAM = multiple trait animal model; SEM = structural equation model
dLFI = daily lactation feed intake (kg/day); dSWB (daily sow weight balance (kg/day); dLWG = daily litter weight gain (kg/day); dBFTB = daily back fat thickness balance (mm/day); SMBW = sow metabolic body weight (kg^0.75)
