Summary

US dairy producers

Area of Science:

  • Agricultural Economics
  • Animal Science
  • Dairy Nutrition

Background:

  • Understanding feed rations is crucial for dairy farm profitability and sustainability.
  • Variations in feedstuff usage exist across different dairy production systems.
  • Data from the USDA Agricultural Resource Management Survey provides insights into farm management practices.

Purpose of the Study:

  • To estimate average feedstuff usage by US dairy producers.
  • To analyze variations in feed rations based on region, production system, and farm size.
  • To compare estimated feed usage with existing university feed cost data.

Main Methods:

  • Utilized data from the 2016 dairy version of the USDA Agricultural Resource Management Survey.
  • Included 955 fully responding farms milking ≥10 cows in major dairy states.

  • Employed t-tests with a delete-a-group jackknife procedure to determine significance of differences.

    • Main Results:

    • Estimated average feedstuff usage at national, regional, production system, and farm size levels.
    • Identified significant differences in feedstuff usage across these categories.
    • Found variations in feed rations influenced by geographical location, farming methods, and herd size.

    Conclusions:

    • Feed ration composition varies significantly among US dairy farms based on region, production system, and size.
    • These findings can inform targeted strategies for feed management and cost optimization in the dairy industry.
    • The study highlights the importance of considering farm-specific factors when analyzing feed usage patterns.
