The HI Cow Family Tournament in 2021 selected Dellia as the Nr.1 cow family of the breed. The figurehead of a current family branch, and a major contributor to that success, was Cookiecutter MOM Halo, who along with her daughter Hanker, have both won Global Cow titles. Halo was a supreme transmitter with daughters by five different bulls – Mogul, Supersire, Day, Massey and Jacey – that have each established major impact family lines now shaping the breed.
