Regression coefficient (β) of telomere length at birth fitted as a covariate to fitness trait analyses, and corresponding correlation estimates from bivariate analyses (standard errors in brackets); only traits with at least one significant result included.

STM12, 24, and 48: survival to 12, 24, and 28 months of age, respectively; HL, herd life measured in days between birth and death (cull); MAST, presence or absence of mastitis in all lactations
RA, genetic correlation; RE, residual correlation; RP, phenotypic correlation
* Statistically different from zero (P < 0.05) before but not after Holm–Bonferroni correction; ** Statistically different from zero (P < 0.05) after Holm–Bonferroni correction.
