【摘要】：畜禽信息主要包括动物健康信息、行为信息、情绪信息。禽畜养殖中,准确高效监测畜禽信息有助于分析动物的生理、健康和福利状况,及时发现生病或异常个体,以减少经济损失和保障动物福利。目前畜禽养殖中主要依靠人工观察方式获取畜禽信息,主观性强且精度低;或者在饲养过程中采用一些将装置植入动物体内或对动物进行手术的监测手段,造成动物应激反应,有损动物福利。无损监测技术可以有效减少人力,降低观察者对动物的影响,减少监测过程中对动物造成的损伤与应激反应,提高动物福利。随着信息技术的进步,畜禽信息无损监测技术也在不断发展。该文阐述了畜禽养殖中传感器监测、图像监测及声音监测3种无损监测技术在获取畜禽信息方面的研究与应用现状,并分析3种无损监测技术的优劣。传感器监测技术发展较其他2种技术相对更加成熟,应用也更加广泛,可用来监测动物饮食、行为姿态等,但适合动物穿戴、可长期高效工作的传感器节点技术有待突破;图像监测技术利用前景提取、模式识别等方法对动物图像进行分析,可进行动物行为识别、质量估计等,对动物影响最小。但目前算法还不成熟,装置受环境干扰较大,因此应用有限;声音监测技术起步较晚,受限于环境噪声的影响,识别正确率较低,但在动物行为监测、疾病预警、情绪识别、饮食监测等方面均有较好的应用前景。该文还展望了畜禽信息无损监测技术未来精准、高效、智能、经济的发展趋势。
[Abstract]:Animal information mainly includes animal health information, behavior information and emotional information. In livestock farming, accurate and efficient monitoring of livestock and poultry information helps to analyze the physiological, health and welfare conditions of animals, and to find sick or abnormal individuals in time. In order to reduce economic losses and protect animal welfare, at present, animal breeding mainly relies on artificial observation to obtain animal and poultry information, which has strong subjectivity and low accuracy. Or in the course of feeding, some monitoring methods are used to implant the device into the animal body or to operate on the animal, which results in the animal stress reaction and impairs the animal welfare. Non-destructive monitoring technology can effectively reduce the manpower. Reduce the impact of observers on animals, reduce damage and stress to animals during surveillance, and improve animal welfare. Non-destructive monitoring technology of livestock and poultry information is also developing continuously. The research and application status of sensor monitoring, image monitoring and sound monitoring in obtaining animal and poultry information in livestock and poultry breeding are described in this paper. The advantages and disadvantages of the three nondestructive monitoring techniques are analyzed. The sensor monitoring technology is more mature and more widely used than the other two technologies. It can be used to monitor animal diet, behavior posture and so on, but it is suitable for animals to wear. The sensor node technology, which can work efficiently for a long time, needs to be broken through. Image monitoring technology can analyze animal images by using foreground extraction, pattern recognition and so on, which can be used for animal behavior recognition, quality estimation and so on. But at present, the algorithm is not mature and the device is greatly disturbed by the environment, so its application is limited. The sound monitoring technology starts late, is limited by the influence of environmental noise, and the recognition accuracy rate is low, but in animal behavior monitoring, Disease early warning, emotion recognition, diet monitoring and other aspects have good application prospects. The article also looks forward to the future development trend of livestock and poultry information nondestructive monitoring technology with precision, high efficiency, intelligence and economy.
