New residual feed intake criterion for longitudinal data

Table 2 SAD models retained for the genetic and environmental components in the phenotypic regression and multi-SAD regression models

	Genetic component	Environmental component
Multi-SAD regression model
ADG	SAD00	SAD00
MBW	SAD00	SAD01
BF	SAD00	SAD01
FI	SAD11^a	SAD12^a
Phenotypic regression model
RFI	SAD11	SAD12

SAD \(\alpha \beta\) implies a polynomial function of degree \(\alpha\) for the antedependence parameter and of degree \(\beta\) for the innovation variance
ADG average daily gain, MBW metabolic body weight, BF backfat thickness, FI feed intake, RFI residual feed intake
^aIn addition, the degree of the functions of the cross-antedependence parameters in the model for FI were all equal to 1 for the genetic and residual parts
