Figure 3From: Genetic effects and correlations between production and fertility traits and their dependency on the lactation-stage in Holstein FriesiansGenotypic correlation between EBVs for production traits and RZR over the first 60 lactation days. EBV: estimated breeding value; RZR: (fertility index, summarizing all fertility traits) filled triangle milk yield; filled circle fat yield; filled square protein yield; empty circle fat content; empty square protein content. Light grey indicates non-significant correlations.Back to article page
