Abstract
Bu çalışma, broylerlerde organ gelişimi üzerine cinsiyet ve aydınlatma programlarının etkilerini incelemek amacıyla yapılmıştır. Toplam 312 adet günlük yaşta civciv (Ross-308) ilk 7 gün ana makinesinde barındırıldıktan sonra iki farklı aydınlatma programının [(23A: 1K) ve (16A: 8K)] uygulandığı iki kümese yerleştirilmiştir. Denemenin 0, 7, 14, 21, 28, 35. ve 42. günlerinde alt grupları temsilen (cinsiyet ve aydınlatma grupları) hayvanların canlı ağırlıkları belirlendikten sonra kesilerek, bazı iç organ ölçümler tespit edilmiştir. Kuluçkadan çıkıştan deneme sonuna kadar, organların büyüme oranlarının belirlenmesinde nonlinear regresyon modellerinden birisi olan Gompertz modeli kullanılmıştır. Cinsiyet faktörünün ince barsak uzunluğu dışında diğer organ ağırlıkları üzerine etkili olmadığı saptanmıştır (P>0.05). Aydınlatma programlarının kalp, karaciğer, ince barsak ağırlığı ve ince barsak uzunluğu üzerine etkisinin önemli olduğu tespit edilmiştir (P<0.05). Gompertz metodu ile hesaplanan, belirleme katsayısı (R2) değerleri kalp, karaciğer, mide ve ince barsak ağırlıkları ile uzunluğu için 0.860-0.960 arasında oldukça yüksek bulunmuştur. Deneme grupları arasında organlara ait büyüme oranları mide için benzer bulunurken, diğer organlarda ise sabit (16A:8K) aydınlatma programında sürekli (23A:1K) aydınlatma programına göre daha yüksek belirlenmiştir. Sürekli ve sabit aydınlatma programları karşılaştırıldığında sabit aydınlatma programının broilerlerde daha yüksek organ gelişimine neden olduğu tespit edilmiştir.
