This study investigates the impact of non-additive genetic effects in estimating variance components and genomic predictions for heat tolerance and performance traits in purebred and crossbred pig populations, and finds that including non-additive genetic effects did not improve the accuracy of genomic breeding values for most traits, but there was animal re-ranking across models and substantial epistatic variance for panting score and hair density in crossbred pigs.
