Mark Yeazel leading Ja-Bob Addiction Rachel-RED EX 91

Our herd is based on the genetics of Sky-Hi Mars Helen-ET RC EX 92, who to date has over 350 known Excellent maternal female descendants around the world and over 1000 VG maternal descendants in 11 countries including the USA, Canada, England, Scotland, Ireland, France, Spain, Switzerland and Australia!

There are over 100 bulls in AI that trace to Helen's maternal line and hundreds more that trace maternally through the male side!
