AI InsightThe standardized data used in this study shows that management practices should be improved in free-range and organic egg production systems to achieve higher sustainability scores in Turkey.
📌 3 Key Takeaways
Abstract
This study aimed to evaluate egg production systems within the scope of sustainability criteria under Turkey conditions. A standardized data approach was used to measure sustainability and compare egg production systems. The study covered a one-year egg-laying cycle of 24 farms including conventional cage, organic, and free-range systems. Hens in conventional cages had higher egg production and lower feed intake compared to hens in organic and free-range systems. The highest mortality was found in the free-range hens while the lowest was in the conventional cage system. All hens were fully feathered in the organic egg production system, which was followed, by free-range and conventional cage. This result led to a better social sustainability score for non-cage systems. Economic issues of sustainability had higher scores in conventional cage and organic egg production than those in the free-range system. The hen number per m2 in the total farm area was lower in organic and free-range than those in conventional cage systems (P=0.003), nonetheless, the total land occupation area was found similar. The standardized data used in this study shows that management practices should be improved in free-range and organic egg production systems to achieve higher sustainability scores in Turkey.
