Death on arrival (DOA) cases are a major concern for poultry farmers and processors. Birds that do not survive transportation result in direct financial losses, operational inefficiencies, and compromised meat quality. Addressing the root causes of DOA can significantly improve processing outcomes and overall profitability.
Key Causes of High DOA Rates
Several factors contribute to increased DOA cases at the processing plant. Poor ventilation, extreme temperatures, overcrowding during transport, and rough handling can lead to excessive bird stress and fatalities. Additionally, long transit durations without access to water or improper feed withdrawal practices may weaken birds, making them more susceptible to mortality before reaching the plant.
Optimizing Transport Conditions to Reduce DOA
Ensuring proper ventilation, temperature regulation, and space allocation in transport crates minimizes stress-related deaths. Choosing the right transport times, particularly during cooler hours, can prevent heat stress. Regular vehicle inspections and driver training also play a crucial role in improving bird survival rates.
Best Practices for Handling and Loading Birds
Proper bird handling reduces physical injuries and stress, lowering DOA cases. Avoiding rough loading techniques, ensuring birds are evenly distributed in crates, and minimizing unnecessary movement can significantly improve survival rates. Trained staff should oversee the loading process to ensure minimal distress.
Pre-Slaughter Management for Healthier Birds
Careful pre-slaughter management, including appropriate feed withdrawal and hydration strategies, helps maintain bird strength before transport. Monitoring bird health on the farm and culling weak or sick birds before transportation prevents unnecessary losses at the processing stage.
Impact of Reducing DOA on Processing Efficiency
Lower DOA rates lead to higher meat yield, reduced waste disposal costs, and improved processing plant efficiency. By implementing better transport and handling strategies, poultry businesses can enhance profitability while maintaining animal welfare standards. Tracking DOA trends over time allows for continuous improvements in transportation and processing practices.
