Pedigree Analysis
K.I. Samen has partnered with Veecom in a breeding adventure entitled “Farmer’s Wish”. The goal of this effort is to provide quality sires for dairy farmers in Europe who are concerned about the lack of diversity in modern bloodlines and the lack of round qualities in many of the bulls offered today.
Olbia is a young bull with an impressive cow family. There were eight generations of his cow family living on the farm at one point! Behind him are five cows who produced over 220,000 lbs in their lifetime. Three of these cows also managed to produce over 22,000 lbs of combined fat and protein.
This kind of longevity is no doubt very rarely seen in an industry that is bent on following hyper-escalating indexes and fast milk.

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.
