Meier et al 2021 Journal of Dairy Science Heifers with positive genetic merit for fertility traits reach puberty earlier and have greater pregnancy rate than heifers with negative genetic merit for fertility traits. Supplementary Figures and Tables. Supplementary Figure 1. Schematic of the process and number of animals at each stage of selecting dams, the contract mating, expected number to calve, calf collection and parentage verification (sire and maternal grandsire) to produce heifers with positive (POS) or negative (NEG) genetic merit for fertility traits. Supplementary Figure 2. Number of daughters per sire for A) sires with positive 941 and B) sires with negative genetic merit for fertility traits. Supplementary Table 1. Supplementary Table 1. The predicted mean Breeding Values (BV) and standard deviation (SD) for the positive and negative Fertility BV offspring based on the completed breeding strategy (Dec 2014). Predictions for heifer offspring are based on parentage averages. Data are provided courtesy of LIC (Hamilton, New Zealand). Supplementary Table 2. A description of the number of heifers from the positive and negative genetic merit for fertility traits that were removed from the study by category and sub-category.
