Effects of alleles in crossbred pigs estimated for genomic prediction depend on their breed-of-origin

BMC Genomics

Table 2 Fixed effects used in the models for each trait for purebred and crossbred pigs

Trait	Population	Fixed effects
BF	Purebred	farm ∗ breed ∗ sex + b_a × off − test BW
BF	Crossbred	trial + farm ∗ sex + b_b × hot carcass weight
ADG	Purebred	farm ∗ breed ∗ sex + b_c × birth weight
ADG	Crossbred	trial + farm ∗ sex + b_c × birth weight
RFI	Purebred	farm ∗ breed ∗ sex + b_d × on − test BW
RFI	Crossbred	trial + farm ∗ breed ∗ sex + b_d × on − test BW

BF = back fat thickness, ADG = average daily gain, and RFI = residual feed intake
b_a, b_b, b_c, b_d, are regression coefficients for off-test BW, hot carcass weight, birth weight, and on-test BW, respectively
