INTRODUCTION
Across the world, the livestock industry contributes significantly to nutritional security, rural livelihoods, farm income, and socio-economic development. Yet, multiple constraints—infectious diseases, suboptimal productivity, climate-induced stress, limited access to veterinary services, poor monitoring, and inefficient breeding—continue to affect farm profitability. Traditional methods of disease detection, fertility management, and herd surveillance often rely on manual observation, which can be inconsistent, labor-intensive, and prone to delayed diagnosis. With the global demand for animal-source foods increasing, there is a growing need for innovation-driven, technology-enabled production systems that enhance efficiency while reducing pressure on natural resources.
Technological advancements such as artificial intelligence (AI), machine learning (ML), nanotechnology, wearable sensors, telemedicine, genomics, precision breeding, and digital data platforms have emerged as transformative tools. These innovations allow veterinarians and farmers to detect abnormalities in animals earlier than ever before, automate herd monitoring, optimize treatment strategies, predict outbreaks, and make evidence-based decisions. Precision Livestock Farming has evolved from a conceptual approach to a practical, farm-scale reality. Similarly, biotechnology has contributed groundbreaking advances in vaccine development, genomic prediction, reproductive engineering, and pathogen characterization.
This article synthesizes these cutting-edge developments under three broad pillars:

By examining the current landscape and future possibilities, this review outlines the path toward constructing intelligent, sustainable, climate-resilient, and welfare-centered animal health systems.
NEXT-GENERATION PRECISION LIVESTOCK TECHNOLOGIES AND AI IN SMART ANIMAL MANAGEMENT
1.1 Concept and Evolution of Precision Livestock Farming
Precision Livestock Farming (PLF) refers to the use of automated tools and data analytics to continuously monitor individual animals and optimize farming decisions. The concept focuses on tracking the animal rather than the herd, recognizing that each animal has unique health needs, feeding patterns, reproductive cycles, and behavioral responses.
Early PLF technologies focused mainly on automated milking and electronic identification systems. Today, sensors, Internet of Things (IoT), cloud analytics, thermal imaging, robotics, and machine learning have expanded the scope of PLF across nutrition, behavior, climate monitoring, disease detection, welfare assessment, and biosecurity.
The core objectives of PLF are:
- Early detection of disease
- Minimal stress and improved welfare
- Maximized production efficiency
- Reduced antibiotic usage
- Real-time decision-making
- Lower labor dependency
- Sustainability through optimized resource utilization
The intersection of PLF with AI-based prediction models is transforming livestock farming from experience-driven to data-driven management.
1.2 Wearable Physiological and Behavior Sensors
