Implication

Predictive modeling study reveals ensemble machine learning accurately forecasts weaning performance in lactating sows, highlighting opportunities for automated precision feeding.

Key Points

To develop machine learning models integrating farm management practices and feed nutrient composition to predict weaning performance and milk quality in lactating sows.
Analyzed 10,089 observations from 17 pig farms across eight provinces in China.
Evaluated 11 statistical and machine learning regression algorithms using stratified sampling, recursive feature elimination, and SHAP value analyses.
Ensemble learning models, specifically random forest and gradient boosting decision trees, performed best with R² values of 0.40 to 0.80 and MAE between 0.11 and 4.36.
Lactation duration, birth litter weight, parity, and day-7 lactation backfat thickness were identified as consistently critical predictors of weaning outcomes across diverse models.
