Amaç: Bu çalışmada, etlik piliçlerde çevresel stresin gelişme performansı, karkas
randımanı ve bazı fizyolojik parametreler üzerine etkileri incelenmiştir.

Materyal ve Metot: Günlük civcivler yüksek sıcaklık, rotasyon, obje kullanımı ve
kontrol olmak üzere rastgele 4 deneme grubuna ayrılmıştır. Sıcaklık grubunda
civcivler denemenin 21. gününde 3 saat süre ile 38±1 ºC sıcak stresine maruz
bırakılmışlardır. Obje grubuna 1-44. günler arasında çevresel zenginleştirme amacıyla
bölmelere yerleştirilen renkli objelerle (ayna, pet şişe, top vb.) görsel uyarıda
bulunularak stres yaratılmıştır. Rotasyon grubundaki piliçler ise haftada iki kere
düzenli olarak bölmeler arası rotasyona tabi tutulmuşlardır. Denemenin 42. gününde
de tüm piliçlere 1 saat süre ile 38±1 ºC sıcak stresi uygulanmıştır.

Bulgular: Çevresel zenginleştirme uygulaması etlik piliç performansını önemli
düzeyde etkilememekle birlikte, 42. gün canlı ağırlığı ve yemden yararlanmayı
iyileştirmiştir. Sıcak stresi uygulanan grubun karkas ağırlığı ve karkas randımanı
değerlerinin kontrol grubu ile benzerlik gösterdiği saptanmıştır. Akut sıcak stresi
sonrasında (21. gün) sıcaklık grubunda trigliserid düzeyinin kontrol grubuna göre
önemli düzeyde daha yüksek olduğu görülmüştür. Deneme sonunda (42. gün) ise
glukoz ve kolesterol değerleri bakımından deneme grupları arasında önemli
farklılıklar oluştuğu belirlenmiştir. Kontrol, obje ve sıcaklık gruplarında kolesterol
seviyeleri benzerlik gösterirken, rotasyon grubunda önemli derecede yükseldiği
saptanmıştır.

Sonuç: Sonuç olarak, erken yaşlardan itibaren zenginleştirilmiş çevrede büyütme
strese adaptasyon sağlanması ve refahın iyileştirilmesi amacıyla yararlanılabilecek bir
yöntem olarak önerilebilir, ancak uygulamaya aktarılabilmesi için daha fazla çalışma
yapılmasına gerek vardır.

Objective: In this study, the effects of environmental stress on growth performance,
carcass yield and some blood parameters of broilers were investigated.

Material and Methods: Day-old chicks were randomly assigned into four treatment
groups (heat stress, rotation, environmental enrichment and control). Chicks in heat
stress group were exposed to 38±1 ºC for 3 hours at the age of 21 days. Chicks placed
in the enriched environment group were reared in pens that contained a variety of
colorful objects (mirror, plastic bottle, ball, etc) between days 1-44. Chicks in the
rotation group were subjected to rotation among pens twice a week. All treatment
groups were exposed to 38±1 ºC for 1 hour on day 42 of the experiment.

Results: Although environmental enrichment did not have a significant effect on the
growth performance of broiler chickens, higher live weight day and improved feed
conversion ratio on day 42 was noted. In heat stress group, carcass weight and
carcass yield were similar to the control group. After exposure to acute heat stress
(21st day), triglyceride levels in heat stress group were significantly higher than that
of the control group. At the end of the experiment (21st day), there were significant
differences between treatment groups in glucose and cholesterol levels. Cholesterol
levels were significantly higher in the rotation group, whereas levels were similar in
control, environmental enrichment and heat stress groups.

Conclusion: In conclusion, rearing in an enrichment environment beginning from
early ages can be recommended as a useful method for adaptation to stress and
improvement of welfare, but further research is needed to put the method in
practice
