Table 2 Fixed effects used in the GBLUP models for average daily gain (ADG), back fat thickness (BF), and loin depth (LD), for purebred (PB) (i.e. S, LR, LW) and three-way crossbred (CB) pigs

ADG

PB

\( {\text{farm}}\_{\text{breed}}\_{\text{sex}}\; + \;{\text{b}}_{{\text{a}}} \times {\text{birth}}\;{\text{weight}} \)

CB

BF, LD

PB

\( {\text{farm}}\_{\text{breed}}\_{\text{sex}} + {\text{b}}_{{\text{b}}} \times {\text{off\_test}}\;{\text{BW}} \)

CB

\( {\text{trial}}\; + \;{\text{farm}}\_{\text{sex}} + {\text{b}}_{{\text{c}}} \times {\text{hot}}\;{\text{carcass}}\;{\text{weight}} \)
