Precision Livestock Farming examines how digital technologies are reshaping animal production in response to the growing demands of food security, sustainability, and animal welfare. Moving beyond herd-level observation, it presents a data-driven approach to monitoring individual animals and managing farm systems with greater precision.Drawing on expertise across animal science, engineering, and economics, the book covers computer vision, artificial intelligence, wearable sensors, robotic milking, virtual fencing, greenhouse gas emissions, and emerging applications in precision entomoculture. It also addresses the practical and economic realities of adoption, including cost-benefit analysis, return on investment, and implementation challenges.As part of the NextGen Agriculture: Novel Concepts & Innovative Strategies series, this book is designed for researchers, students, and industry professionals, offering an overview of the opportunities and constraints shaping the future of livestock production.
