Bar JZ Ranches is the breeder of 10 Focus Dams, ranking them 8th in the nation.

      Each year, NALF honors the elite cows of the breed in the Focus Dams list. To be awarded the distinction of being a Focus Dam, cows must have three or more calves reported to NALF and progeny weaning weights must be reported in contemporary groups.
      Females must then meet stiff criteria for maximum age at last calving and have a Most Probable Producing Ability (MPPA) of 105 or greater. MPPA is expressed as a ratio and measures a cow's maternal ability to wean heavy calves relative to calves in the same weaning group.
      Focus Dams are then divided into two categories: Proven Dams and Prospective Dams. Proven Dams must have at least 6 calves, while Prospect Dams are those with three, four or five calves. With these stringent requirements, only 142 proven cows and 187 prospect females qualified as Focus Dams this year.
