Optimizing Broiler Performance: Advanced Strategies for Stress Reduction and Enhanced Welfare

In the competitive landscape of modern poultry farming, the pursuit of maximum broiler production often intersects directly with the imperative of animal welfare. Stress, a silent yet potent adversary, can significantly undermine the productivity and profitability of any broiler operation. For poultry farmers, feed manufacturers, veterinary professionals, and students alike, a deep understanding of stress factors and the implementation of sophisticated management techniques are paramount. This comprehensive guide delves into the intricate mechanisms of broiler stress and outlines advanced, actionable strategies to mitigate its impact, ensuring robust health, optimal growth, and superior economic returns.

The Multifaceted Impact of Stress on Broiler Physiology and Productivity

Stress in broilers is more than a fleeting discomfort; it triggers a cascade of physiological responses that can derail an entire production cycle. The activation of the hypothalamic-pituitary-adrenal (HPA) axis leads to elevated corticosteroid levels, particularly corticosterone. This hormonal shift has profound implications:

• Immunosuppression: Chronic stress weakens the immune system, making birds highly susceptible to bacterial, viral, and parasitic infections, leading to increased medication costs and mortality.
• Metabolic Disruption: Energy is diverted from growth processes (protein synth
