The welfare of animals has profound implications not only for ethical and social reasons but also for product quality, disease control, and environmental impact. Thus, improving animal welfare is a shared responsibility of farmers, technologists, policymakers, and consumers [2].
In the pursuit of superior animal welfare practices, objective indicators have emerged as indispensable tools for informed decision-making [3]. They provide a means to quantify and monitor welfare status, enabling early detection of potential issues, measuring the impact of interventions, and facilitating continuous improvement. Traditional assessment methods, relying on subjective evaluations or periodic physical examinations, can be labor-intensive, time-consuming, and prone to inconsistency [4]. The complexity of animal welfare, with its intricate interplay of physical, physiological, and behavioral factors, calls for more comprehensive and objective assessment methods.
This is where the role of sensor technology and artificial intelligence (AI) becomes paramount. In the age of digital transformation, these technologies offer compelling solutions to revolutionize livestock farming [5]. Sensor technologies, including wearable devices and environmental monitoring systems, can continuously capture a vast array of data points, such as body temperature, heart rate, movement patterns, feeding behavior, and environmental conditions. When coupled with AI algorithms, these data can provide real-time, objective, and holistic insights into animal welfare [6]. AI's prowess in handling large data sets allows for precise and predictive analysis, making it possible to preempt health issues, optimize living conditions, and promote natural behaviors.
However, the successful deployment of these advanced technologies fundamentally depends on one crucial factor - the farmer. A farmer-centric approach is vital to ensure that technologies truly serve the needs of farmers and the welfare of animals [7, 8]. Farmers' deep-rooted understanding of their animals and their environments must be the guiding force behind technological advancements. Technology should be a tool to enhance farmers' capabilities, not to override them. A farmer-centric approach facilitates the design of intuitive, practical, and affordable solutions [9]. Moreover, it promotes technology acceptance and proper usage, ultimately leading to sustainable and effective animal welfare management.
In this comprehensive review, we delve deeper into these pertinent topics. The first section presents a detailed discussion on animal welfare and the importance of objective indicators. The following section elucidates the role and potential of sensor technology and AI in livestock farming. We then discuss the crucial role of a farmer-centric approach for technology adoption and animal welfare management. Each section will not only provide a synthesis of current knowledge but also highlight gaps and suggest directions for future research. The objective is to provide a robust, farmer-centric framework to harness the potential of sensor technology and AI for the advancement of animal welfare.
This review seeks to spark dialogue among farmers, technologists, researchers, and policymakers, fostering a collective commitment towards the shared goal of improving animal welfare. By illuminating the opportunities and challenges of this exciting frontier, we hope to contribute to the evolution of modern livestock farming that embraces technology while honoring timeless farming wisdom.

2. Animal Welfare Indicators: From Traditional Approaches to Sensor Technology and AI-driven Solutions

2.1. Understanding Animal Welfare Indicators

Animal welfare encapsulates the physical, physiological, and behavioral health of animals, thus requiring a spectrum of indicators for comprehensive assessment [10]. Traditionally, these three aspects have been examined separately, each providing vital insights into the overall wellbeing of an animal.
Health Indicators: Health indicators are often the most direct measures of an animal's wellbeing, manifesting in tangible signs such as the presence of disease, injuries, or changes in physical condition. These indicators are crucial in evaluating the quality of an animal's life and its exposure to potential stressors [11, 12, 13].
Behavioral Indicators: Behavior stands as a window into an animal's mental state, often indicating its comfort, stress, or frustration levels. These indicators can range from eating and sleeping patterns to social interaction and exhibition of natural behaviors. Deviations from normal behavior can indicate physical illness, environmental stress, or psychological discomfort [14, 15].
Physiological Indicators: Physiological parameters, such as heart rate [16], body temperature, and levels of stress hormones, provide an objective assessment of an animal's response [17] to its environment. While less obvious to the naked eye, these indicators offer precise measurements and can detect issues that may not be visible in the animal's behavior or physical condition.
