[Objective] This paper tries to forecast the trends of poultry market influenced by multiple factors, aiming to strengthen the decision makings and policies for livestock and poultry production.[Methods] We chose 50 variables to construct machine learning models for predicting daily turnovers of dressed chicken. Our models were created based on popular machine learning algorithms.[Results] We found that GBRT, Random Forest and Elastic Net yielded stable prediction results and their MAEs were 25.30, 26.67, and 28.21 respectively. The prediction was improved with more large training sets and longer training time. We could forecast the turnovers of three periods in advance.[Limitations] The training sets needs to include more features and historical data.[Conclusions] The proposed models could quantatively assess and forecast the impacts of emergencies on industrial output, which imrpoves governmental policy making.
