Abstract: Core body temperature is one of the most critical physiological indicators of vital signs in livestock and poultry. Effective monitoring and regulation of body temperature is critical for accurately assessing the health and physiological status of cattle and poultry. The article outlines the present state of the use of various livestock and poultry automatic temperature monitoring systems in the sustainable growth of livestock and poultry production during the last five years. The study focuses on the invasive, wearable and non-contact techniques of automatic temperature monitoring in cattle and poultry, as well as their applications. The benefits and drawbacks of various monitoring methods in terms of data accuracy, ease of operation, real-time data, equipment stability, and animal welfare considerations were assessed using three criteria: technology, cost, and application issues. Invasive temperature monitoring is highly accurate and stable over long periods, making it ideal for scientific research that requires high-precision monitoring. However, this monitoring approach requires well-trained workers to operate, which puts a lot of pressure on the target animals, makes data exchange inconvenient, and has issues with sensor loss and displacement. Wearable monitoring is simple to use and convenient for data collection, making it highly suitable for long-term continuous temperature monitoring in large-scale livestock breeding, such as pigs and cattle. However, the monitoring location and usage method have a significant impact on the accuracy of temperature monitoring and the comfort of target animals. Non-contact monitoring is extremely sensitive and stress-free, making it ideal for grouped monitoring of cattle and poultry animals. However, the accuracy of temperature measurement in this monitoring method is heavily influenced by factors such as the external environment, equipment accuracy, testing distance, and testing area. This paper makes recommendations for the development of several ways of automatic temperature monitoring in livestock and poultry. In terms of invasive temperature monitoring, efforts should be focused on the research and development of new biocompatible materials, as well as non-invasive/minimally invasive and low-power data communication technologies, to reduce the stress response of the target animal and improve the system's overall practicality. In terms of wearable temperature monitoring, the emphasis should be on optimizing the wearing mode, conducting research on anti-interference algorithms, multi-sensor technology fusion, new energy conversion and other technologies to improve animal comfort and temperature measurement accuracy. Non-contact temperature monitoring requires improving the performance of thermal infrared sensors, conducting research on the adaptability of temperature measurement for different species and incorporating deep learning technologies to build a more accurate temperature monitoring model to improve measurement accuracy. The goal of the research is to develop convenient, efficient, low-cost and high-precision temperature measurement devices or application modes to meet the temperature-measuring needs of large-scale livestock and poultry breeding operations. Non-contact temperature monitoring, also known as thermal infrared technology, is expected to become the primary technology for accurate temperature monitoring of large-scale livestock and poultry due to its high sensitivity, absence of stress reaction, and adaptability to group monitoring. Non-contact monitoring will accelerate the transformation of the livestock and poultry industry towards an intelligent and efficient development by standardizing the monitoring process, integrating automated deep-learning collection systems, improving algorithm robustness and opening significant development opportunities. This article aims to provide reference for researchers in the field of automatic temperature monitoring for livestock and poultry, in order to promote the development of livestock and poultry farming towards a more intelligent and efficient direction.
