Pedigree Analysis
The Ginger family has done amazing things for the Petersheim family in Viroqua, WI. When it comes to transmitting power, Granola is the best of the best at Welsh-Edge Holsteins. She currently has 11 classified daughters; 7 are EX and 4 are Very Good, with the lowest scored daughter at VG-87!
Granola, who lived to be 12 years old and produced nearly 230,000 lbs of lifetime milk is one of those rare cows who doesn’t miss when it comes to passing her greatness on through her progeny.
When we had the opportunity to take on this polled A2/A2 Rex-PP-Red son from Granola’s EX Windbrook daughter, we knew Great Guy fit the Triple-Hil mold. Combining Rex’s consistent transmitting pattern with this proven maternal line should produce uniform results in your herd. We look for bulls that we believe will pass on balance, consistency, and longevity. Great Guy checks the boxes!

305-AA is the standardized milk, fat, and protein yield estimate used by CDCB to compare cows of different ages, parities, breeds, and regions on equal footing. According to CDCB and USDA AGIL, it represents “a 305-day lactation record at 36 months of age” — hence “Average Age,” or AA.
It replaced 305-ME (Mature Equivalent) in June 2024 for published records and was implemented in the calculation of CDCB genetic evaluations effective August 13, 2024. ME had been the standard since 1935.
How it is calculated
The new factors are applied as a series of separate multipliers for age-parity, season, previous days open, and milking frequency. Lactation records are adjusted upward or downward to what the cow would have been expected to produce as a 36-month-old, milked twice daily for 305 days.
Key adjustments include:
- Age-parity: Standardized to 36 months rather than ME’s mature range of 61–86 months depending on breed.
- Season/climate: Seasonal effects are now estimated within five regions defined by the average climate zone scores for each state, replacing the old three east-to-west geographic regions.
- Milking frequency: Still standardized to 2x milking, unchanged from ME.
- Previous days open: The methodology for this adjustment is also unchanged from ME.
