Introduction
Artificial intelligence (AI) is rapidly transforming various sectors, and agriculture is no exception (Zhang et al., 2024). In animal agriculture, AI offers innovative ways to enhance animal welfare, improve production efficiency, and promote sustainability (Bao and Xie, 2022; Gadzama and Ray, 2024; Vlaicu et al., 2024). AI is not meant to replace farmers but to assist and enhance their capabilities by providing them with tools to manage their farms more effectively (Neethirajan, 2024). This article explores how AI is used in livestock farming, including the benefits and challenges.
Historical Context and Evolution of AI
The concept of AI dates back to the Dartmouth Conference in 1956, but its application in animal farming began in the 1970s (Bao and Xie, 2022). Early applications involved expert systems to diagnose vitamin deficiencies in chicks (Bao and Xie, 2022). In the 1980s, computer-based image analysis was used to study animal behavior, and models were developed to simulate animal-habitat interactions (Bao and Xie, 2022). Now, with advancements in machine learning and deep learning, AI has become an essential tool in modern animal agriculture (Zhang et al., 2024).
What is Artificial Intelligence in Animal Farming?
AI in animal farming involves using computer systems to perform tasks that typically require human intelligence. These tasks include analyzing data, making decisions, and even controlling farm equipment (Melak et al., 2024). AI systems use algorithms and machine learning models to learn from data collected by sensors, cameras, and other devices (Neethirajan, 2020).
How AI Works in Animal Farming
AI systems in animal farming rely on collecting and analyzing large amounts of data. This data can come from various sources, including:
- Sensors: These devices monitor animal activity, body temperature, heart rate, and other physiological parameters (Melak et al., 2024).
- Cameras: Video footage can be analyzed to detect changes in animal behavior, such as signs of illness, stress, or discomfort (Zhang et al., 2024).
- RFID tags: Radio-frequency identification tags can track individual animals (Bao and Xie, 2022).
- Environmental sensors: These sensors track barn conditions such as temperature, humidity, and air quality (Vlaicu et al., 2024).
The collected data is then processed by AI algorithms, which learn from the data and make predictions or decisions (Neethirajan, 2020). Machine learning, a part of AI, helps systems get better over time without needing new instructions (Melak et al., 2024). Deep learning, another subset of AI, uses complex networks to understand detailed data patterns (Zhang et al., 2024).
Applications of AI in Animal Farming
Artificial intelligence is increasingly being used in various aspects of animal farming to improve production, animal welfare, and farm management. This technology helps farmers monitor animal health, optimize feeding, manage resources, and make better-informed decisions.
Animal Identification
AI-powered computer vision systems can automatically identify individual animals through unique facial features or body patterns, making it easier to track their health and performance (Billah et al., 2022; Mahato and Neethirajan, 2024). This is a significant improvement over traditional methods, like manual record-keeping (Melak et al., 2024).
- Behavior Monitoring: AI algorithms analyze sensor and video data to detect deviations from normal behavior patterns, which can indicate illness or stress (Zhang et al., 2024). For example, AI can monitor a sow's increased activity, predicting the start of parturition (Küster et al., 2020; Zhang et al., 2024). Real time monitoring of cows for signs of sickness, stress, or discomfort is possible by using sensors and cameras with AI features (Mahato and Neethirajan, 2024). For instance, AI can detect changes in movement, feeding habits, and body temperature that may indicate a problem (Gadzama and Ray, 2024). This technology can also predict disease outbreaks.
- Disease Detection and Management: AI can detect early signs of disease by analyzing physiological data, like body temperature, heart rate, and activity levels (Melak et al., 2024). This enables farmers to intervene early, preventing outbreaks and reducing losses (Zhang et al., 2024). Some AI systems can detect mastitis in dairy cows using automatic milking systems (Sun et al., 2010).
Precision Feeding
AI can analyze each animal's nutritional needs using real-time data, optimizing feed to ensure they get the right nutrients (Zhang et al., 2024). This improves growth and efficiency (Vlaicu et al., 2024), reduces waste, lowers costs, and promotes sustainable practices (Zhang et al., 2024).
Growth Estimation
AI models can predict animal growth rates, helping farmers adjust feeding plans and optimize production (Vlaicu et al., 2024). AI can also help analyze the growth performance of poultry (Ahmad, 2009).
- Environmental Control: AI systems monitor barn conditions (temperature, humidity, air quality), and adjust ventilation to ensure optimal living conditions for animals (Bao and Xie, 2022).
- Reproductive Management: AI algorithms can analyze data to optimize breeding programs and improve reproductive success (Melak et al., 2024). AI models can predict milk production based on animal genetics, feed composition, and environmental conditions to help farmers with planning (Rosati, 2024).
- Automated Tasks: Robots powered by AI can automate routine tasks, such as feeding, milking, sorting, and cleaning barns. Robotic milking systems and automated feeding systems are used to improve the farm's operational efficiency. This reduces the workload on farmers (manual labor) and ensures that each cow receives the care it needs. For example, AI analyzes data on individual cows to suggest the best feeding schedules. This ensures that the animal gets the right amount of food, thereby improving feeding efficiency (Melak et al., 2024).
- Data Analysis and Decision Making: AI can integrate data from multiple sources, giving farmers insights into all aspects of their operations and assisting them in making well-informed decisions about breeding, feeding, and disease control (Rosati, 2024), and methane mitigation. This is done by collecting information with the help of advanced internet of things (IoT) sensors both inside and outside the farm (Rosati, 2024).
Benefits of Using AI in Animal Farming
- Improved Animal Welfare: AI allows for continuous monitoring of animal health and behavior. It helps detect health problems early, enabling farmers to quickly address any issues and create a better living environment for their animals (Gadzama and Ray, 2024; Linstädt et al., 2024).
- Increased Efficiency: AI can optimize feeding, breeding, and resource allocation, leading to higher yields and lower costs (Vlaicu et al., 2024).
- Reduced Labor Costs: Automation through AI-powered robots can reduce operational costs and increase farm profitability (Melak et al., 2024).
- Early Disease Detection: AI can detect the early signs of disease, allowing for timely treatment and reducing losses (Melak et al., 2024).
- Enhanced Product Quality: AI can help improve the quality of meat, milk, and eggs through close monitoring of animal health and the environment (Vlaicu et al., 2024).
- Sustainability: AI can help optimize resource use, including managing water and feed more efficiently, and reducing waste and environmental impact (footprints) of livestock farming (Rosati, 2024).

Striking a balance between welfare monitoring and preserving animals' independence is important (Zhang et al., 2024). The use of wearable sensors and continuous surveillance could impact animals' natural behaviors, cause discomfort, or disrupt social dynamics, and it is imperative to create ethical guidelines to ensure that monitoring prioritizes the welfare of the animals (Neethirajan, 2024).
- Potential for Misuse of Data: The data generated from AI systems is vast and can be used in various ways, both beneficial and potentially harmful (Neethirajan, 2024). It is important to have robust guidelines and regulations in place to ensure that data is used responsibly and ethically to protect against data misuse (Neethirajan, 2024).
- Algorithmic Bias and Transparency: The inherent lack of transparency in some AI algorithms can impede our ability to comprehend and trust the recommendations they generate, particularly when trained on biased or incomplete datasets (Neethirajan, 2024; Neethirajan, 2024). It is important to create AI systems that are transparent and easily interpretable so users can validate AI decisions, identify potential biases, and ensure ethical and welfare considerations are upheld (Neethirajan, 2024).
- Impact on Human-Animal Interaction: Over-reliance on technology may reduce human-animal interaction, potentially undermining farmers' moral and emotional responsibilities toward their animals (Papakonstantinou et al., 2024). It is important to balance technological integration with the need to preserve human-animal bonds and ethical responsibilities (Papakonstantinou et al., 2024).
Practical Challenges
- Complexity and Integration: Integrating AI into farm operations can be complex and may require changes to established practices (Rosati, 2024). Farmers need to adapt to new workflows and develop technical skills to manage AI technologies effectively (Rosati, 2024). Successful adoption requires a systemic approach involving data collection devices, data processing, and smart algorithms (Bao and Xie, 2022).
- Need for Skilled Personnel: Implementing and maintaining AI systems requires personnel with expertise in both agriculture and data science (Gras et al., 2024). Lack of such knowledge and training can hinder the adoption of AI technology (Zhang et al., 2024).
- Trust in AI: Some farmers may find it difficult to trust AI systems, especially when recommendations seem counterintuitive (Rosati, 2024). Building trust in AI requires transparency and evidence of the system’s reliability (Rosati, 2024).
Addressing the Challenges
To overcome these challenges, a multi-faceted approach is needed. This will help ensure the successful adoption and ethical use of AI in animal farming.
- Investment in Research and Development: Continued research is essential to improve the accuracy, reliability, and cost-effectiveness of AI technologies for animal farming (Mahato and Neethirajan, 2024). Focus should be placed on developing AI models that are adaptable to diverse environments and ensure ethical deployment (Mahato and Neethirajan, 2024).
- Collaboration and Knowledge Sharing: Collaboration between researchers, farmers, policymakers, and technology developers is vital to addressing the challenges effectively (Rosati, 2024). Sharing best practices and research findings can accelerate the adoption of advanced technologies (Gras et al., 2024).
- Ethical Frameworks and Guidelines: Developing clear ethical guidelines for the use of AI in animal farming is important to ensure that the technology is used responsibly and ethically (Neethirajan, 2024). These guidelines should address issues such as animal privacy, data security, and responsible AI deployment (Neethirajan, 2024).
- Training and Education: Providing farmers and agricultural workers with the necessary training and education to manage and utilize AI technologies is essential for successful adoption (Rosati, 2024). Training programs should focus on both the technical aspects of AI and the practical applications in farm settings (Zhang et al., 2024).
- Connectivity Issues: Reliable internet connection can be a problem in some rural and remote farms, but microservice-oriented design can help overcome that limitation (Zhang et al., 2024).
Conclusion
