Özet:

 The aim of this research is to evaluate the effects of light intensity and the temperature-humidity index THI on egg performance and growth rate in laying hens reared on different cage tiers. Additionally, the study seeks to un-derstand the sensitivity and efficiency of chickens comfort conditions under various climatic environmental conditions. Brown layer Hyline Brown hens were used as the animal material. In the experiment, 392 hens were housed in a total of 56 cages, with 7 hens per cage in a 4-tier cage system. During the experiment, live weights, growth rates, egg pro-duction, and egg weights of the hens were recorded and correlated with the THI and light intensity values measured in front of each cage. The results indicated that hens on the upper tiers had higher live weights, body weight gains, growth rates, egg production, and egg weights compared to those on the lower tiers. A negative relationship was found between the THI value and both growth rate and egg production. Increasing THI values negatively affected both body weight and egg production. Significant positive relationships were observed between light intensity and egg weight, egg production, and average egg production. In conclusion, environmental management and physiological factors are crucial in optimizing the performance of laying hens. Appropriate housing conditions, including optimal light intensity, and temperature management, are essential for maximizing both growth and reproductive performance. Additionally, achieving an ideal body weight at the beginning of the productive period is a crucial for egg production.

 Bu araştırmanın amacı, farklı kafes katlarında yetiştirilen yumurtacı tavuklarda ışık şiddeti ve sıcaklık-nem indeksi-nin yumurta performansı ve buyume hızı uzerine etkilerini değerlendirmektir. Ayrıca çalışma, çeşitli iklimsel çevre ko-şulları altında tavukların konfor koşullarının hassasiyetini ve verimliliğini anlamayı amaçlamaktadır. Hayvan materyali olarak kahverengi yumurtacı Hyline Brown tavukları kullanıldı. Denemede 4 katlı kafes sisteminde kafes başına 7 tavuk olacak şekilde toplam 56 kafese 392 tavuk yerleştirildi. Tavukların canlı ağırlıkları, buyume oranları, yumurta uretimleri ve yumurta ağırlıkları kaydedilerek her kafesin önunden ölçulen THI ve ışık şiddeti değerleri ile ilişkilendirildi. Araştır-mada, ust kattaki tavukların canlı ağırlık, buyume hızı, yumurta uretimi ve yumurta ağırlığı değerleri alt kattakilere göre daha yuksekti. THI değeri ile hem buyume hızı hem de yumurta uretimi arasında negatif bir ilişki bulundu. THI değeri-nin artması hem canlı ağırlığı hem de yumurta uretimini olumsuz etkiledi. Işık şiddeti ile yumurta ağırlığı, yumurta ureti-mi ve ortalama yumurta uretimi arasında önemli pozitif ilişkiler gözlendi. Sonuç olarak, çevre yönetimi ve fizyolojik fak-törler yumurtacı tavukların performansının optimize edilmesinde çok önemlidir. Optimum ışık şiddeti ve sıcaklık yöneti-mi de dâhil olmak uzere uygun barınma koşulları, hem buyume hem de ureme performansını en ust duzeye çıkarmak için gereklidir. Ayrıca, uretim dönemi başında ideal canlı ağırlığa ulaşılması yumurta uretimi için çok önemlidir.
