Multi-story Pig Farming In Sichuan Province China

Multi-story Pig Farming in Sichuan Province, China: A Sustainable Agricultural Innovation
Sichuan Province, China's largest pork-producing region, is revolutionizing livestock farming with multi-story "pig apartment buildings." This vertical farming approach addresses land scarcity and environmental concerns while maintaining high production capacity.
Smart Design and Technology
The Anyue County smart pig farm exemplifies this innovation. Its six-story facility houses 7,800 breeding sows and 43,000 finishing pigs on just 50 mu (8 acres) of land – a sixfold reduction compared to traditional farms requiring 300 mu. Each floor maintains constant temperature (22°C) and humidity (30-50%) through automated environmental control systems. Pigs travel between floors via elevators, reducing stress and disease risk.
Environmental Benefits

Multi-story farms integrate sophisticated waste management. Slatted flooring allows manure to fall through for collection and processing. The Anyue facility's 40,000 cubic meter oxidation pond treats wastewater for agricultural irrigation. Exhaust air passes through deodorizing water-curtain walls, removing over 95% of odors and ammonia before release.
Economic Advantages
Automation dramatically improves labor efficiency – one worker manages 2,800 pigs compared to 600-800 on conventional farms. The Anyue facility's annual output reaches 260 million yuan ($36 million USD). Government incentives include 100,000 yuan payments for farms reaching production milestones and 50 yuan per sow subsidies.
Global Relevance
China has constructed nearly 4,500 multi-story pig buildings supporting approximately 2.65 million breeding sows. Vietnam and other Asian nations are now adopting this model to address similar land and environmental challenges.
