Feeding behavior is one of the critical welfare indicators of broilers. Hence, understanding feeding behavior can provide important information regarding the usage of poultry resources and insights into farm management. Monitoring poultry behaviors is typically performed based on visual human observation. Despite the successful applications of this method, its implementation in large poultry farms takes time and effort. Thus, there is a need for automated approaches to overcome these challenges. Consequently, this study aimed to evaluate the feeding time of individual broilers by a convolutional neural network-based model. To achieve the goal of this research, 1500 images collected from a poultry farm were labeled for training the You Only Look Once (YOLO) model to detect the broilers' heads. A Euclidean distance-based tracking algorithm was developed to track the detected heads, as well. The developed algorithm estimated the broiler's feeding time by recognizing whether its head is inside the feeder. Three 1-min labeled videos were applied to evaluate the proposed algorithm's performance. The algorithm achieved an overall feeding time estimation accuracy of each broiler per visit to the feeding pan of 87.3%. In addition, the obtained results prove that the proposed algorithm can be used as a real-time tool in poultry farms.
采食行为是肉鸡重要的福利指标之一。因此,了解采食行为可以提供有关家禽资源利用情况的重要信息,并有助于洞察农场管理。监测家禽行为通常基于人工视觉观察。尽管这种方法有成功的应用案例,但在大型家禽养殖场实施起来既耗时又费力。因此,需要自动化方法来克服这些挑战。因此,本研究旨在通过基于卷积神经网络的模型评估个体肉鸡的采食时间。为实现本研究目标,从一个家禽养殖场收集了1500张图像,用于训练You Only Look Once(YOLO)模型以检测肉鸡的头部。还开发了一种基于欧几里得距离的跟踪算法来跟踪检测到的头部。所开发的算法通过识别肉鸡头部是否在喂食器内来估计其采食时间。应用三个1分钟的带标签视频来评估所提算法的性能。该算法在每次肉鸡访问食槽时的采食时间总体估计准确率达到了87.3%。此外,所得结果证明所提算法可作为家禽养殖场的实时工具使用。
