- Residual Feed Intake: A minor calculation update reflects current standards in calculating milk energy content. This change had very little impact on Predicted Transmitting Abilities (PTAs).
- Rear Teat Placement (RTP) in Brown Swiss: The CDCB RTP evaluations are now integrated into the international evaluation process, which had a noticeable impact on Brown Swiss RTP results for males and females.
- Net Merit $ trends: The NM$ trends for all breeds now exclude animals with missing breed codes for the sire and crossbred animals. With this change, expect a more stable NM$ trend for Ayrshire and Milking Shorthorn. In other breeds, the NM$ trends are not affected.
CDCB and USDA AGIL geneticists detail the changes here.
