Genetic Evaluation of Beef Sires Using a Beef‐on‐Dairy Crossbred Reference Population
Journal of Animal Breeding and Genetics, Volume 143, Issue 3, Page 390-402, May 2026.ABSTRACT In recent years, Beef‐on‐Dairy (BoD) crossbreeding programs have gained momentum to enhance dairy cattle's economic and genetic merits while meeting the demand for high‐quality beef. However, bulls with superior growth potential can lead to calving problems; thus, Holstein dairy farmers must decide which semen to use to avoid calving problems ...
