Alternative broiler production methods focus on housing, management, and welfare systems rather than feed innovations. Key approaches include pasture‑based pens, net‑range paddocks, and modified confinement with outdoor access, all designed to improve sustainability, animal welfare, and farm profitability.
Introduction
Broiler production has traditionally relied on intensive confinement systems, but growing consumer demand for welfare‑friendly and environmentally responsible poultry has encouraged exploration of alternative methods. These systems aim to balance productivity with ecological and social benefits1.
Pastured Poultry Pens
One widely adopted method is the floorless portable pen system, where broilers are enclosed in mobile pens moved daily to fresh pasture. Birds consume grass, insects, and supplemental feed while naturally fertilizing the soil. This model reduces waste concentration and integrates poultry into agroecological cycles. However, it requires high labor input and exposes birds to predation risks2.
Net‑Range or Day‑Range Systems
Another alternative is the net‑range system, which uses movable housing combined with electric fencing to create paddocks. Birds rotate through paddocks, accessing forage while being sheltered from weather and nocturnal predators. This system offers greater flexibility and protection compared to simple pasture pens, though it still faces challenges with avian predation and land management.
Modified Confinement with Outdoor Yards
Producers can adapt conventional confinement houses by adding fenced yards or pasture access during daylight. This approach allows integration of organic or free‑range certification standards while maintaining existing infrastructure. The main risks include soil degradation and pathogen buildup if pastures are not subdivided or rotated effectively.
Environmental and Welfare Benefits
Alternative systems contribute to improved animal welfare, enabling natural behaviors such as scratching and foraging. They also enhance soil fertility and reduce reliance on synthetic fertilizers. From a sustainability perspective, these methods lower environmental footprints compared to fully confined operations, though they may reduce growth rates and increase production costs.
Economic Considerations
Profitability in alternative broiler production depends on market premiums for organic or free‑range products. While input costs and labor demands are higher, niche markets often compensate through consumer willingness to pay more for welfare‑friendly poultry. Enterprise models suggest that profitability is achievable if producers manage land rotation, predator control, and direct marketing effectively.
Conclusion
Alternative broiler production methods—pastured pens, net‑range systems, and modified confinement with outdoor yards—offer viable pathways toward sustainable poultry farming. They improve welfare, integrate ecological benefits, and meet consumer demand for ethical products. Future research should refine pasture management, predator mitigation, and economic modeling to support broader adoption.
