Farklı Işık Kaynaklarının (Monokrom Işık ve Floresan) Broylerlerde Besi Performansı Üzerine Etkisi

Bu çalışma, farklı ışık kaynaklarının (monokrom ve floresan) broylerlerde besi performansı parametreleri üzerine etkilerini incelemek amacıyla yapılmıştır. Toplam 216 adet günlük yaşta civciv (Ross-308) ilk 7 gün ana makinesinde barındırıldıktan sonra üç farklı aydınlatma programının uygulandığı kümeslere yerleştirilmiştir. Birinci deneme grubuna (SBKAL) soğuk beyaz renkli (5500 Kelvin) LED ışık kaynağı ile 14 saat aydınlatma yapılmış, ayrıca sabah ve akşam olmak üzere günde 2'şer kez 20 dakika kırmızı (1500 Kelvin) ve 40 dakika amber rengi (2500 Kelvin) LED ışık verilmiştir. İkinci kümeste (SBL) soğuk beyaz LED (5500 Kelvin), üçüncüde ise (BFL) beyaz floresan (4000 Kelvin) ışık kaynakları ile sabit aydınlatma programı (16A:8K) uygulanmıştır. Deneme gruplarına ait haftalık periyotlarla, canlı ağırlık, canlı ağırlık artışı ve yem tüketimi değerleri karşılaştırılmıştır. Aydınlatma parametreleri bakımından deneme grupları arasında farklılığın istatistiksel olarak önemli olmadığı belirlenmiştir (SBKAL: 2389.39 g, SBL: 2338.22 g ve BFL: 2436.32 g), (P>0.05). Denemenin 1, 2 ve 4. haftasında canlı ağırlık bakımından gruplar arasında farklılık tespit edilememiştir (P>0.05). Ancak 3. haftada SBKAL ve 5. haftada BFL grubunda en hızlı büyümenin gerçekleştiği görülmüştür (P

The Effects of Different Light Sources (Monochromatic Light and Fluorescent) on Fattening Performance in Broilers

This study was undertaken to investigate the effect of different light sources (monochrome and fluorescent) on fattening performance parameters (body weight, live weight gain, feed consumption, feed conversion ratio) of broilers. Totally, 216 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 three lighting regimes: SBKAL [(2L (amber color and yellow) + 14L (cool white LED): 8D)], SBL [16L (cool white LED): 8D)] and BFL [(16L (fluorescent) :8D)]. At weekly intervals, body weight (BW), live weight gain (LWG), feed consumption (FC) and feed conversion ratio (FCR) was recorded on group basis. The results indicated no differences in body weight in week 6 (SBKAL: 2389.39 g, SBL: 2338.22 g ve BFL: 2436.32 g), (P>0.05). The effect of the different color of the LEDs and fluorescent bulbs on live weight gain were not statistically significant in first, second and fourth weeks of ages of the broilers (P>0.05). However in the third and fifth weeks of experiment, the fastest growing group was found to be SBKAL and BFL groups (P
