Early genomic prediction of daughter pregnancy rate is associated with improved reproductive performance in Holstein dairy cows

Autor: F.T. Silvestre, Fabio S. Lima, William W. Thatcher, Francisco Peñagaricano

Publikováno v: Journal of Dairy Science. 103:3312-3324

The use of genomic testing for selecting replacement heifers in commercial farms has recently attracted much attention. Fertility traits are among the most complex, hard to measure, and lowly heritable traits, and hence they can benefit the most from
