This invention relates to a method for predicting sow estrus based on low-cost electronic ear tags, belonging to the field of smart animal husbandry technology. Addressing the problems of high cost and model overfitting in automated sow estrus detection in large-scale farming, this invention uses low-power electronic ear tags worn on the sow's ear to collect ear temperature data in real time, and performs multiple calibrations to ensure data stability. Its core components include: employing an hourly average body temperature resampling strategy to construct a 48-hour regularized time-series feature sample set to enhance the model's generalization ability; constructing a classification model based on a lightweight gradient boosting machine (LightGBM); and innovatively designing a "Forced Offspring Iteration" (FOI) mechanism to improve the genetic algorithm for global optimization of model hyperparameters. This mechanism improves convergence efficiency while maintaining search capability by cutting off parental gene transmission. This invention can achieve reliable automatic identification of sow estrus using low-cost sensing data.
