  1. 1The effect of the haplotype was estimated as the least square mean values of GLM analysis. The statistical model for GLM analysis included fixed effects for the farm, birth year and haplotype. The genetic variance explained by the haplotype was calculated based on estimates of the haplotype effect and the frequency of the haplotype [40]. Total genetic variance was estimated by MTDF-REML programs. The effect size of a haplotype was estimated as the proportion of genetic variance explained by the haplotype.
  2. 2The average NCP4 values for QQ and qq are 2.789 days and 2.683 calves.
  3. 3The results were tested by a one-way ANOVA, followed by a Tukey-Kramer test for multiple comparisons.
