Abstract

This study was undertaken to investigate the effect of gender and lighting regimes on organ growth of broilers. Totally, 312 head one day old chicks (Ross-308) were kept in brooder for the first 7 d, then transferred into the cages, in which the animals were exposed to two lighting regimes [(23L: 1D) and (16L: 8D)]. The samples from sub-groups (gender and lighting groups) were weighed, slaughtered and internal organs were weighed to determine the organ growth on the days zero, 7, 14, 21, 28, 35 and 42 throughout the experiment. To determine the growth rate of organs from the brood to the 42nd d of the experiment, non-parametric Gompertz model was used. Except for the length of the intestine, other organ weights were not affected by the gender of the animals (P>0.05). Lighting regime had significant effect on heart, liver, intestinal weight and intestinal length (P

Özet

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
