The objective of this study was to investigate the feasibility and resulting accuracy from using all available phenotypic, pedigree, and genomic information. Evaluations were performed by regular \BLUP\ or by \BLUP\ with the traditional pedigree and genomic relationships combined in a unified single-step procedure (SSP). Genetic parameters of \CR\ in the first 3 parities were estimated with data from New York State only. Heritability estimates were around 2% and genetic correlations between \CR\ in different parities were >0.73. The \R2\ obtained with the \SSP\ were almost twice as large as those achieved with regular BLUP. Computing the \SSP\ took 2 h, and it was 33% slower than a regular BLUP. A multiple-trait evaluation of \CR\ using the \SSP\ is both possible and advantageous.
