Estimated effects of genomic inbreeding coefficients $F_{\text{grm}}$ and $F_{\text{ped}}$ on LBS (number of calves produced) in each sex, and on LRS (number of calves surviving to independence at age 2 y) in females

The models simultaneously estimate the effect of inbreeding coefficients on the probability of breeding (“Prob. LBS > 0,” binomial part) and on the number of offspring, conditional on having at least one offspring (“LBS when > 0,” truncated Poisson part). Significant effects (P ≤ 0.05) are indicated in bold. The estimates for the random effects in each model are given in Table S3. Sample sizes ranged from 384 to 458 (see Table S2).

^*LRS, rather than LBS, is used for M13.
