Effect of predictor traits on accuracy of genomic breeding values for feed intake based on a limited cow reference population
The genomic breeding value accuracy of scarcely recorded traits is low because of the
limited number of phenotypic observations. One solution to increase the breeding value
accuracy is to use predictor traits. This study investigated the impact of recording additional
phenotypic observations for predictor traits on reference and evaluated animals on the
genomic breeding value accuracy for a scarcely recorded trait. The scarcely recorded trait
was dry matter intake (DMI, n= 869) and the predictor traits were fat–protein-corrected milk …
