Özet
Amaç: Bu çalışma monokromatik aydınlatmanın etlik piliç performansı, karkas özellikleri ve bazı kan parametreleri üzerine etkilerini belirlemek için gerçekleştirilmiştir. Materyal ve Metot: Toplam 504 adet günlük erkek civciv (Ross-308) her biri 4 tekerrürlü (42 civciv) 3 muamele grubuna [kompakt floresan (KF)- kontrol, mavi led (ML)-470 nm ve yeşil led (YL)-570 nm] ayrılmıştır. Deneme boyunca hayvanlara 23 s aydınlık ve 1 s karanlık aydınlatma programı uygulanmıştır. Tüm gruplarda hayvanlar ışık geçirmez bölmelerde barındırılmış ve aynı başlatma (0-21. günler) ve bitirme (22-45. günler) yemi ile beslenmişlerdir. Yem ve su ad-libitum tüketime sunulmuştur. Bulgular: Denemenin 21. gününde ML grubunun canlı ağırlığı KF ve YL gruplarına göre önemli düzeyde azalmıştır. Çalışmanın sonunda, en yüksek canlı ağırlığa YL grubu ulaşmıştır. Monokromatik mavi aydınlatma, 0-21. günler arasında yemden yararlanmayı olumsuz yönde etkilemiştir. Kolesterol düzeyi hariç, muamele grupları arasında kan parametreleri ve kesim özellikleri bakımından önemli bir fark belirlenmemiştir. ML grubunda 40. gün kan kolestrol düzeyi artmıştır. Sonuç: Sonuç olarak, etlik piliç üretiminde performansın iyileştirilmesi amacıyla YL uygulaması önerilebilir.
Objective: In this study, it was conducted to determine the effects of monochromatic lighting on performance, carcass characteristics and some blood parameters of broilers. Material and Methods: A total of 504 one day old chicks (Ross-308) were randomly divided into 3 treatment groups [compact fluorescent (CF)-control, blue led (BL)-470 nm and green led (GL)-570 nm] in 4 replicates each (42 chicks). The animals were exposed to a lighting schedule of 23 h of light and 1 h of dark throughout the experiment. The animals in all groups were housed in light-proof (opaque) pens and fed on same starter (from 0 to 21 days) and finisher (from 22 to 45 days) diets. Feed and water were offered for ad-libitum consumption. Results: Body weight of BL at 21 days significantly decreased compared to CF and GL groups. At the end of the study, GL group reached the highest body weight. Monochromatic blue lighting adversely affected feed conversion ratio from 0 to 21 days. No significant differences were determined in blood parameters except cholesterol level and slaughter characteristics between treatment groups. On 40 days, blood cholesterol level increased in BL group. Conclusion: As a result, it might be suggested GL treatment to improve performance in broiler production.
