A report from the Penn State Extension team indicates that age at first calving for dairy heifers continues to decline, which in turn can save producers money.
In the report, Jud Heinrichs and Coleen Jones say that average age at first calving for dairy heifers in Pennsylvania in 1985 was 26.9 months, compared to 25.5 months in 2011.
Current recommendations are for age at calving is 23 to 24 months of age.
When age at calving increases, so does the need for heifer housing, feed, labor, and management, so reducing the age at first calving can lead to better heifer economics.
