Pedigree Analysis
Meet Radix, our newest star! This Rex-PP-Red son hails from a “hidden gem” cow family in southwestern PA. Radix is a beautiful blend of the round traits of his sire and the incredible dairyness and angularity of his dam. Pronto Lynita is a cow who brings everything together in one package…gorgeous confirmation, great production, super high components, fertility and longevity.
This cow family is known for their transmitting ability and longevity. The 3rd dam of Radix, Elk-Lick Charles Ardel, lived to be 18 years old and was dam of 15 EX and 19 VG daughters! Her Durham daughter also lived to be 12 years old. This incredible will to live carries on to Radix’s dam as she is 11 years old and still in the milking string.
With his impressive proven parentage on both sides of the pedigree and the wonderful qualities that he displays we think this bull will live up to his name–Radix: “the source or origin”.

comparable PTAT bulls
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.
