动物福利仍然是畜牧业的一个非常重要的问题，但客观、持续地监测动物福利仍然是一个严峻的挑战。基于生理测量而不是行为的视听评分来监测动物福利将是向前迈出的一步。与福利和压力相关的明显生理信号之一是心率。这项研究的目的是利用很快就能负担得起的技术来测量猪的心率（每分钟心跳）。如今，人们使用光电体积描记法 (PPG) 技术对人体进行大规模的经济实惠的心率监测。我们在猪身上使用 PPG 传感器来测试它是否可以检索可靠的心率信号。开发了一种基于连续小波变换 (CWT) 的算法来解耦猪的心脏脉搏波。测试了三种不同的小波，即二阶、四阶和六阶高斯导数 (DOG)。我们展示了所开发的基于 PPG 的算法的结果，以心电图 (ECG) 作为心率的参考测量，并且针对麻醉动物与非麻醉动物进行比较。我们测试了三种不同的身体解剖位置（耳朵、腿和尾巴），并给出了传感器每个身体位置的结果。综上所述，可以得出结论，基于 PPG 的心率技术与参考传感器之间的一致性在 91% 到 95% 之间。在本文中，我们展示了使用基于 PPG 的技术评估猪心率的潜力。
Animal welfare remains a very important issue in the livestock sector, but monitoring animal welfare in an objective and continuous way remains a serious challenge. Monitoring animal welfare, based upon physiological measurements instead of the audio–visual scoring of behaviour, would be a step forward. One of the obvious physiological signals related to welfare and stress is heart rate. The objective of this research was to measure heart rate (beat per minutes) in pigs with technology that soon will be affordable. Affordable heart rate monitoring is done today at large scale on humans using the Photo Plethysmography (PPG) technology. We used PPG sensors on a pig′s body to test whether it allows the retrieval of a reliable heart rate signal. A continuous wavelet transform (CWT)-based algorithm is developed to decouple the cardiac pulse waves from the pig. Three different wavelets, namely second, fourth and sixth order Derivative of Gaussian (DOG), are tested. We show the results of the developed PPG-based algorithm, against electrocardiograms (ECG) as a reference measure for heart rate, and this for an anaesthetised versus a non-anaesthetised animal. We tested three different anatomical body positions (ear, leg and tail) and give results for each body position of the sensor. In summary, it can be concluded that the agreement between the PPG-based heart rate technique and the reference sensor is between 91% and 95%. In this paper, we showed the potential of using the PPG-based technology to assess the pig′s heart rate.
