Results of the model sensitivity analysis for feed efficiency simulated at the lifetime level and second lactation level. FE_life, ratio between cumulative energy for milk production and cumulative energy acquired, from birth to death; FE_lac2, ratio between cumulative energy for milk production and cumulative energy acquired, from second parturition to second drying-off. The sensitivity analysis was based on a complete factorial design combining three levels (L: low; M: medium and H: high) of the four genetic-scaling parameters that drive allocation to growth (G2S _GEN ), allocation to lactation (Pc2S _GEN ), basal acquisition (AcqB _GEN ) and lactation acquisition (AcqL _GEN ). Red dots represent the mean values
