Timing is Everything

About this episode

This episode discusses the critical importance of timing in cattle data collection and its impact on genetic evaluations.

In this episode of Behind the Beef , Madison and Becky emphasize that when it comes to cattle data, timing is everything . The discussion focuses on how age windows and submission deadlines impact the reliability and usefulness of genetic evaluations. Why Timing Matters for Data Collection Actual performance data is standardized to specific age endpoints to allow for fair comparisons within Expected Progeny Differences (EPDs) . Age Windows : Breed associations set specific age ranges (e.g., 320 to 440 days for yearlings) where they feel confident adjusting data. Consequences of Missing Windows : Data collected outside these windows will not be used for EPD calculations. While the record still exists, it essentially "doesn't count" for genetic predictions. The "Best" Calves Risk : Often, a producer’s best calves (AI-sired, born early) are at the highest risk of aging out of the window if weighing is delayed. Subjective Scoring and Consistency For traits that rely on human observation, timing and consistency are paramount: Udder Scores : These must be collected within 24 hours of calving . Scoring them months later makes the data meaningless. Foot and Body…
