Figure 2: Relationship between age and FCR of broiler birds during a growing cycle Rearing broilers is associated with increasing costs, however, this does not mean heating should be withdrawn at about 2 to 3 weeks of age, as birds still require optimal environmental conditions to convert feed efficiently into muscle rather than using energy to maintain body temperature. 3. Striking a balance: cost-cutting vs welfare and productivity While reducing operational costs is essential for maintaining profitability, farmers must strike a balance that does not compromise bird welfare or productivity. Optimising heating systems after 21 days can help maintain performance while controlling costs. 3.1. Regular maintenance and system upgrades One of the most effective ways to improve heating efficiency is through regular maintenance and system upgrades. Investing in energy-efficient heating systems can reduce energy consumption while maintaining optimal temperatures in the broiler house. 3.2. Temperature monitoring and control Temperature monitoring and control systems allow farmers to manage heating more effectively. Some affordable devices would give indications of house temperatures and relative humidity. Automated systems can adjust heating levels based on bird age, external weather conditions, and time of day. This ensures birds remain comfortable while minimising unnecessary energy use. 3.3. Improved insulation and ventilation Proper insulation helps minimise heat loss and maintain stable temperatures within broiler houses. Insulating walls, ceilings, and floors helps conserve heat and reduces the need for excessive heating. Efficient ventilation systems also improve air quality, reduce moisture buildup, and control ammonia levels, creating a healthier environment for broilers. 4. A sustainable approach to heating systems Cost-cutting strategies that compromise heating systems can negatively affect broiler welfare, growth, and profitability. Maintaining optimal environmental conditions ensures birds convert feed efficiently into muscle rather than using energy to maintain body temperature. Investing in efficient heating systems, proper insulation, and real-time monitoring helps farmers maintain bird comfort while minimising energy costs. Additionally, proper ventilation must not be sacrificed when heating is applied. Good ventilation removes excess moisture, improves air quality, and reduces harmful gas buildup while maintaining thermal comfort. You can ventilate while heating up your profit. Properly balancing heating and ventilation allows farmers to maintain bird welfare, improve performance, reduce mortality, and ultimately increase profitability. Striking the right balance between cost management and environmental control is essential for sustainable and profitable broiler production.
