Pedigree Analysis
This Jonah son from the heart of Mt-Glen’s ‘L’ family is now proven, with already well over 100 milking daughters in his proof.
Lithium carries a rare aAa code of 4-6-5, and we are observing him to be transmitting these qualities well. The Lithium daughters exhibit wide, rugged frames with deep chests and good bone substance. Their udders are generally not flashy, but solid and functional. The oldest daughters at Mt-Glen are already classified Very Good in their second lactation.
Lithium himself is one incredible individual, with an impressive upstanding front end, tremendous rib and excellent feet & legs.
If you’re looking for a bull who can add a high dose of strength and substance to your tall narrow cattle, Lithium is your bull!

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.
