摘　　要：马岗鹅的行为与其生长状况和福利状况密切相关,马岗鹅关键行为监测对评估其生长性能具有重要的现实意义。为了实现对群养栏马岗鹅关键行为高效率精准监测,该研究探索一种基于YoloX的群养马岗鹅关键行为监测算法(Magang geese behavior monitoring of based on Double Head-YoloX,MGBM-DH-YoloX),该算法通过减少YoloX的头部数量提升检测效率、使用损失函数减少前景背景干扰、使用迁移训练方式提高网络训练效率等技术对马岗鹅采食、饮水、休息和应激等关键行为及其规律进行分析。MGBM-DH-YoloX首先用Mosaic和Mixup对马岗鹅图像进行数据增强,然后使用增强后的数据集训练模型,并且利用模型检测马岗鹅的关键行为,最后累计得出马岗鹅关键行为的发生时长和行为节律;试验训练集为1400幅、验证集200幅和测试集为400幅,连续活动视频10 d。结果表明,MGBM-DH-YoloX算法的平均精度为98.98%、检测速度达到81帧/s、内存消耗为2520.04 MB。对马岗鹅的10 d养殖数据分析发现,MGBM-DH-YoloX能有效观察到马岗鹅随着日龄增长采食次数逐渐减少;试验鹅每日采食与饮水行为同时出现的比例为83.74%,呈现整体相伴趋势,但也从90.78%降低到74.57%,说明马岗鹅采食与饮水行为随着日龄增加呈现出逐渐分离趋势;试验鹅随着日龄增长休息时间逐渐加多,呈现出肉鸭对笼养的适应性逐步增强;应激行为随机性很强,突发性明显,发现人员随机走动等不规范饲喂带来的应激行为占据很大比例。该研究显示MGBM-DH-YoloX算法能利用监控视频对马岗鹅的关键行为进行智能提取,可为家禽智能养殖监管提供技术支撑。The vital behaviors of Magang geese are closely related to their growth and welfare status.Therefore,it is very necessary to accurately identify the key vital behaviors of Magang geese in husbandry and production.This study aims to efficiently and accurately monitor the key behaviors of Magang geese in pens.An improved algorithm was also proposed for the vital behavior of Magang geese using Double Head-YoloX(referred to as MGBM-DH-YoloX).The detection efficiency of the network was enhanced to reduce the number of YoloX heads.A tradeoff was made to balance the foreground and background using the Focal loss objective function.Efficient network training was achieved using migration training.Other techniques were utilized to identify the vital behavior and count their key behaviors once at a fixed time in an efficient and accurate way,including the identification and rule analysis of key behaviors,such as feeding,drinking,rest and stress of Magang Geese.Firstly,MGBM-DH-YoloX enhanced the data of the Magang geese images with Mosaic and Mixup.And then the enhanced dataset was used to train the DH-YoloX(Double Head-YoloX)for the detection of the vital behavior of the waterfowl.Finally,the vital behavior of the Magang geese was counted every 25 frames.The experiment was conducted in a flock-reared environment with the Magang geese as the subject of the case study.A behavioral target detection test was conducted during this time.Waterfowl videos were collected on multiple days from 26 December 2021 to 04 January 2022,and from 10-12 May 2022 at the Nanwei Building Experimental Farm,School of Animal Science,South China Agricultural University,Tianhe District,Guangzhou City,Guangdong Province,China.A platform was also built to acquire the data for the behavior detection of geese.The color images of Magang geese were facilitated to integrate the environmental factors in the vicinity of the breeding pen(the height of the pen,as well as the width and height of the equipment box).The bi-directional difference frame was adopted t
