Overview

This analysis demonstrates the regression model for predicting body weight in Holstein cattle, indicating the relevance of body measurements.

Key Points

  • The body weight composite (BWC) predicts body weight for Holstein cattle in intensive systems.
  • A total of 701 records were analyzed to establish the BWC based on specific traits.
  • Using linear regression, R² was 0.617, showing a moderate fit for predicting weights.
  • The average prediction error was 3.2%, suggesting BWC is a reliable weight indicator for these cows.
