In Dairy Herd Improvement (DHI) records, what does RHA stand for?

• A. Rolling Herd Average
• B. Routine Health Assessment
• C. Registered Herd Analysis
• D. Regional Herd Average

Answer: (A)

Rolling Herd Average (RHA) is a key metric used in Dairy Herd Improvement (DHI) records to assess the productivity of a dairy herd over a specified period, typically calculated on a 365-day basis. This measurement reflects the average milk production for a herd, which helps producers to understand and track their herd's performance more effectively over time. The RHA is particularly useful because it smooths out variations in milk production that can occur due to seasonal changes, varying feed quality, or individual cow health issues. By calculating the average in a rolling manner, it gives a continuously updated picture of the herd’s performance, allowing dairy producers to make informed management decisions regarding breeding, feeding, and overall herd health. This can ultimately lead to improved productivity and profitability of the dairy operation. The other options refer to different terms that do not align with the commonly accepted terminology in dairy herd metrics, making RHA the correct and most relevant term in this context.
