Amaç: Bu araştırma yumurtacı bıldırcın rasyonlarına ketencik (Camelina sativa L.) küspesi ilavesinin performans ve yumurta kalite özellikleri ile serum ve yumurtada lipid peroksidasyon üzerine etkisini belirlemek amacıyla yapıldı.Gereç ve Yöntem: Araştırmada toplam 240 adet (160 dişi ve 80 erkek) sekiz haftalık Japon bıldırcını (Coturnix coturnix japonica) her biri 48 bıldırcından oluşan 1 kontrol ve 4 deneme grubuna ayrıldı. Her bir grup da 12 bıldırcından oluşan 4 alt gruba ayrıldı. Kontrol grubu ketencik küspesi (KK) ilavesi yapılmayan (%0 KK) soya fasülyesi küspesi temeline dayanan temel rasyonla beslendi. Deneme gruplarının rasyonlarında KK %5 (KK5), 10 (KK10), 15 (KK15) ve 20 (KK20) düzeylerinde kullanıldı. Araştırma 8 haftada tamamlandı.Bulgular: Araştırmada yem tüketiminin KK15 ve KK20 gruplarında en düşük olduğu belirlendi (P

Aim: This study was carried out to determine the effects of false flax (Camelina sativa L.) meal supplementation to laying quail diets on performance, egg quality traits, and lipid peroxidation in serum and eggs. Materials and Methods: A total of 240 (160 females and 80 males) eight-week-old Japanese quails (Coturnix coturnix japonica) divided into one control group and four treatment groups containing 48 quails. Each group was divided into four replicate groups each containing 12 quails. The control group was fed diet containing soybean meal basis without false flax meal (0% FFM). The FFM was used at level of 5% (FFM5), 10% (FFM10), 15% (FFM15), and 20% (FFM20) in treatment diets. The experimental period was lasted for 8 weeks.Results: The results showed that feed intake was lowest in the FFM15 and FFM20 groups (P<0.01). Final body weight (P<0.05) and egg production (P<0.01) decreased in the FFM15 and FFM20 groups compared with the control group. Egg yolk color index increased in the FFM20 group in the 4th week (P<0.001) and in all experimental groups in the 8th week (P<0.01). Dietary FFM supplementation did not affect initial body weight, egg weight, feed efficiency, egg shape index, egg shell thickness, egg albumen index, egg yolk index or Haugh unit. The serum malondialdehyde level decreased (P<0.05) in the FFM10, FFM15, and FFM20 groups, while the serum antioxidant activity level increased (P<0.01) in all experimental groups compared with the control group. The egg yolk malondialdehyde level decreased in all experimental groups compared with the control group on the 1st (P<0.05) and 15th (P<0.001) days of storage.Conclusion: It may be stated that supplementation of up to 10% of FFM to diets prevents lipid peroxidation without adversely affect on the performance in laying quails.
