Area of Science:

  • Agricultural Economics
  • Animal Science
  • Machine Learning

Background:

  • Dairy farm profitability is significantly influenced by cow replacement decisions.
  • Dynamic programming (DP) offers optimal replacement policies but is computationally intensive for daily use.
  • Machine learning (ML) can provide fast, accurate predictions for complex variables in DP models.

Purpose of the Study:

  • To develop and validate a machine learning model that mimics dynamic programming (DP) for predicting dairy cow retention pay-off (RPO).
  • To assess the accuracy and efficiency of using ML in conjunction with DP for dairy replacement decisions.

Main Methods:

  • A DP model was used to generate a dataset of 122,716 records with calculated RPO under 27 economic scenarios.
  • A machine learning model tree algorithm was employed to replicate the DP-derived RPO.
Keywords:

  • The model's performance was evaluated using correlation coefficients and relative absolute error on simulated and real-world dairy herd data.

    • Main Results:

    • The ML model tree achieved a high concordance with DP, showing a 0.991 correlation coefficient and 0.10 relative absolute error on simulated data.
    • The model demonstrated low error rates for binary classification of RPO (1% false negatives, 9% false positives).
    • Application to actual herd data yielded a 0.994 correlation and 0.10 relative absolute error, confirming its predictive power.

    Conclusions:

    • Model trees show significant potential for complementing DP in dairy replacement decision-making.
    • This integrated approach enables faster and more accurate predictions, assisting farmers in optimizing herd management.
    • The study validates the use of ML for practical application of complex economic models in agriculture.
