Abstract

The objective of the current study was to determine the effects of monochromatic lighting on female broiler performance for 42 d rearing period. 480 female broiler chicks (Ross-308) were divided into three lighting treatment groups in four replicates each. All birds were housed three independent rooms previously divided by wooden bars into 12 sealed cells of 4 m2 (40 chicks each one). Average light intensity was 10 lux for all groups. A 23-h photoperiod was provided for first 7 d, followed by an 18- h photoperiod through to 42 d. Lighting treatments were: 1- control daylight (mini incandescent light bulbs for 42 days); 2- 560 nm Green LED (G) for first 3 wks and 480 nm Blue LED lamps (B) lamps for remaining 3 weeks; named G-B group and last group; 3- G for first 3 wks and G-B mix for remaining 3 weeks; named G-GB MIX group. At weekly intervals, mortality, body weight (BW), live weight gain (LWG) and feed consumption (FC) was recorded on group basis. A significant increase in BW, LWG and FC was observed in broilers reared under G-B and G-GB mix lighting compared to control group. G-B and G-GB mix significantly increased carcass weight compared to control group. We suggest that green light from hatching to 21 d of rearing period and switching it to blue or green-blue mix emitted from monochromatic (LED) lamps beneficially influence performance traits of female broilers.

Özet

Bu çalışma farklı dalga boyuna sahip monokromatik ışık kaynaklarının 42 günlük yetiştirme periyodu boyunca dişi broylerin performansına etkilerinin belirlenmesi amacıyla yürütülmüştür. Çalışmada 3 farklı ışık grubu oluşturulmuş ve her gruba ait 160’ ar hayvan denemede kullanılmıştır. Her grup için 4 alt grup oluşturulmuştur. Her deneme grubu birbirinden bağımsız odalara yerleştirilmiş ve her bir alt grup 4 m2’lik 12 bölmeye yerleştirilmiştir (her bölmede 40 civciv). Gruplarda ortalama ışık şiddeti 10 lüks olarak ayarlanmıştır. Işık denemeleri; 1- Kontrol grubu (mini flüoresan lamba- günışığı); 2- ilk 3 hafta 560 nm dalga boyundaki yeşil ışık (G) ve son 3 hafta 480 nm dalga boyundaki mavi ışık (B)’ın kullanıldığı G-B olarak adlandırılan grup ve son olarak 3- ilk 3 hafta G ışık kaynağının kullanıldığı kalan 3 hafta ise G-B ışıklarının karışık olarak kullanıldığı ve G-GB mix olarak adlandırılan grup şeklinde planlanmıştır. Monokromatik ışık kaynağı olarak LED’ler kullanılmıştır. Denemede haftalık periyotlarla, ölüm oranı, canlı ağırlık (BW), canlı ağırlık kazancı (LBW) ve yem tüketimi (FC) değerlendirilmiştir. Araştırma sonuçlarına göre G-B ve G-GB mix gruplarında BW, LWG ve FC bakımından önemli iyileşmeler bulunmuştur. Ayrıca G-GB mix grubunda karkas ağırlığı bakımından kontrol grubuna göre önemli ilerlemeler tespit edilmiştir. Çalışma sonuçlarına göre, dişi broyler yetiştiriciliğinde yetiştirme periyodunun ilk 3 haftası G kalan 3 haftalık periyot için ise GB mix ışıklandırma modelinin uygulanması tavsiye edilebilir.
