Minimizing negative and promoting positive emotional states are central to animal welfare. Evaluating these states in dairy cattle under farm conditions is challenging yet vital. This review highlights behavioral (e.g., play, body language), physiological (e.g., heart rate variability, infrared thermography), and cognitive (e.g., judgment bias, flexibility) indicators for assessing emotional states. The selected examples highlight the potential effects of different management conditions on the positive or negative emotional state and cognitive functioning of dairy cattle. Advances in automation have opened avenues for continuous assessment of the mental states of dairy cattle on-farm; this will enable adjustments to management practices to meet individual needs and improve animal welfare.
尽量减少负面情绪并促进积极情绪状态对动物福利至关重要。在农场条件下评估奶牛的这些情绪状态具有挑战性，但至关重要。本综述重点介绍了用于评估情绪状态的行为（如玩耍、肢体语言）、生理（如心率变异性、红外热成像）和认知（如判断偏差、灵活性）指标。所选示例突出了不同管理条件对奶牛积极或消极情绪状态及认知功能的潜在影响。自动化的进步为在农场持续评估奶牛的心理状态开辟了道路；这将有助于调整管理措施以满足个体需求并改善动物福利。
