Bu çalışmada, farklı tünek sistemlerinin etlik piliçlerde canlı ağırlık, yem tüketimi, yemden
yararlanma ve yaşama gücüne etkilerinin belirlenmesi amaçlanmıştır. Yedinci hafta canlı ağırlık
ortalamaları kontrol grubunda, yatay tünekli grupta, 10° açılı tünekli grupta, 20° açılı tünekli
grupta ve 40o açılı tünekli grupta sırasıyla 2745,7±356 g, 2722,1±341,8 g, 2804,3±364,4 g,
2727,5±378,7 g ve 2737,5±372,2 g olarak saptanmıştır. Canlı ağırlığa cinsiyetin etkisi önemli,
buna karşın grup etkisi önemsiz bulunmuştur. Yem tüketimi bakımından gruplar arasında
önemli farklılıklar ortaya çıkmış (P < 0,01) olup en fazla yem tüketimi 10° eğimli tünekli grupta
(4975,6±493,1 g) elde edilmiştir. Yemden yararlanma oranı bakımından da gruplar arasındaki
farklılık önemli bulunmuştur (P < 0,01).

The aim of this study was to determine the effects of different perch systems on body weight, feed consumption, feed conversion and survival rate. At the age of 7 weeks, body masses were determined as 2745,7±356 g, 2722,1±341,8 g, 2804,3±364,4 g, 2727,5±378,7 g and 2737,5±372,2 g in control, horizontal perch, 10° angled perch, 20o angled perch and 40o angled perch groups, respectively. There was a significant difference between the sexes with respect to body weight, but differences among the groups were not significant. The differences between the groups were found to be significant in terms of feed consumption and highest feed consumption was determined in 100 angular perch group (4975,6±493,1 g). Also, a significant difference was found between these groups with respect to feed conversion ratio (P<0,01).
