Simple Summary: Circular RNAs (circRNAs) are derived from regions that are transcribed but do not code for proteins. Instead, they form covalent closed-loop structures and play a crucial role in many biological processes. This literature review focuses on the function of circRNAs in cattle, goats, and sheep, with a particular emphasis on their impact on economically significant traits such as milk production, meat quality, muscle development, wool production, etc. Additionally, the review explores the potential of circRNAs as biomarkers for the assessment of animal health and welfare. An enhanced understanding of circRNAs' roles can significantly improve the management of farm animals and the quality of products derived from them. This is increasingly relevant in a context where consumer concerns about animal welfare and sustainable farming practices are growing. The insights provided here pave the way for future studies, highlighting the importance of circRNAs in advancing livestock practices. Circular RNAs (circRNAs) are unique noncoding RNA molecules, notable for their covalent closed-loop structures, which play a crucial role in regulating gene expression across a variety of biological processes. This review comprehensively synthesizes the existing knowledge of circRNAs in three key livestock species: Bos taurus (cattle), Ovis aries (sheep), and Capra hircus (goats). It focuses on their functional importance and emerging potential as biomarkers for disease detection, stress response, and overall physiological health. Specifically, it delves into the expression and functionality of circRNAs in these species, paying special attention to traits critical to livestock productivity such as milk production, meat quality, muscle development, wool production, immune responses, etc. We also address the current challenges faced in circRNA research, including the need for standardized methodologies and broader studies. By providing insights into the molecular mechanisms regulated by circRNAs, this review underscores their scientific and economic relevance in the livestock industry. The potential of circRNAs to improve animal health management and the quality of animal-derived products aligns with growing consumer concerns for animal welfare and sustainability. Thus, this paper aims to guide future research directions while supporting the development of innovative strategies in livestock management and breeding. [ABSTRACT FROM AUTHOR]
