This study reviews recent advancements in precision livestock farming (PLF) technologies and their applications in addressing challenges related to animal welfare and climate change. Over the past 50 years, the demand for meat has significantly increased, leading to a rise in livestock numbers and environmental sustainability issues. PLF technologies aim to enhance efficiency, reduce environmental impact, and improve animal health and welfare. However, the adoption of these technologies faces several challenges, including technical complexity, high initial costs, and ethical concerns regarding animal welfare. The legal framework for PLF is also discussed, highlighting the need for further research and ethical considerations in its implementation. The study emphasizes the importance of balancing technological advancements with sustainable practices to ensure the long-term viability and ethical treatment of animals in the livestock industry.This study reviews recent advancements in precision livestock farming (PLF) technologies and their applications in addressing challenges related to animal welfare and climate change.
