Trait	Resilience Phenotype	V_P	V_A	h²
Lamb	Response	9.51E-03 ± 1.85E-04*	1.39E-03 ± 2.65E-04*	0.146 ± 0.027*
Lamb	Stability	5.27E-03 ± 1.02E-04*	7.29E-04 ± 1.44E-04*	0.138 ± 0.026*
Ewe	Response	1.21E-02 ± 3.24E-04*	6.86E-04 ± 3.38E-04*	0.057 ± 0.028*
Ewe	Stability	6.92E-03 ± 1.86E-04*	2.34E-04 ± 1.77E-04	0.034 ± 0.026

Response resilience phenotype reflecting change in average weight gain per unit of air temperature change (°C); Stability absolute value Response (square root transformed); V_P phenotypic variance; V_A additive variance; h² heritability; * = significantly different from 0 (P < 0.05)
