Abstract

Bu çalışma, yumurtacı Japon bıldırcınlarında zeytin yaprağı özütü (OLE), zarlı yumurta kabuğu (ESM), zarlı yumurta kabuğuna emdirilmiş zeytin yaprağı özütü (OLE+ESM) ilavesinin performans, yumurta kalitesi, kan ve kemik parametreleri üzerine etkilerini belirlemek için yapılmıştır. Toplam olarak 112 adet 45 günlük yumurtacı bıldırcın, 4 tekerrürlü 4 gruba ayrılmıştır. Bıldırcınlar; i) bazal diyet ii) bazal diyete 400 ppm OLE ilavesi iii) bazal diyete %2 zarlı yumurta kabuğu ilavesi iv) bazal diyete 400 ppm OLE+%2 ESM ilavesi şeklinde 4 diyetle beslenmiştir. Yumurta ağırlığının OLE grubunda daha yüksek olduğu gözlenmiştir (P<0,05). Toplam yem tüketimi ESM ve OLE+ESM gruplarında artmıştır (P<0,05). Yumurta üretimi ve yem dönüşüm oranı, kontrol ve OLE+ESM gruplarında daha iyi bulunmuştur (P<0,01). Şekil indeksi OLE, ESM ve OLE+ESM gruplarında daha yüksek bulunmuştur (P<0,05). Ak ve kabuk oranı, ESM grubunda anlamlı olarak düşük tespit edilmiştir (P<0,01). ESM ve OLE ilavesi sarı oranı, kabuk kalınlığı, kabuk külü ve sarı rengini etkilememiştir (P>0,05). Tibia kemik parametrelerinde istatistiksel fark bulunmamıştır. En düşük serum laktat dehidrojenaz konsantrasyonu (LDH) kontrol grubunda gözlenmiştir (P<0,01). Serum ürik asit düzeyi ESM grubunda azalmıştır (P<0,01). OLE ilavesinin bıldırcın beslenmesi üzerinde sınırlı etkileri olmuştur. Sonuç olarak, OLE ve ESM'nin ayrı ayrı kullanımları önemli etkiler göstermezken, OLE ve ESM karışımının yumurta kalitesini ve performans parametrelerini olumlu yönde etkilediği görülmüştür.

The effects of dietary supplementation of olive leaf extract and eggshell with membrane on performance, egg quality, blood biochemical, and bone parameters in laying Japanese quail

Abstract

This study was conducted to determine the effects of dietary supplementation of olive leaf extract (OLE), eggshell with the membrane (ESM), and the ESM that absorbed the OLE (OLE+ESM) on the performance, egg quality, biochemical, and bone parameters in laying Japanese quail. A total of 112 quail, being 45-day-old, were divided into 4 groups with 4 replicates. The quail were fed with four diets: i) basal diet ii) basal diet supplemented with 400 ppm OLE iii) basal diet supplemented with 2% ESM, and iv) basal diet supplemented with 2% ESM that absorbed with 400 ppm OLE. Egg weight was observed to be higher in the OLE group (P<0.05). Total feed intake increased in ESM and OLE+ESM groups (P<0.05). Egg production and feed conversion ratio were found to be better in control and OLE+ESM groups (P<0.01). Shape index was higher in OLE, ESM and OLE+ESM groups (P<0.05). Percentages of albumen and shell were significantly lower in ESM group (P<0.01). Percentage of yolk, shell thickness, shell ash, and yolk color were not affected by the supplementation of ESM and OLE groups (P>0.05). There was no statistical difference in tibia bone parameters (P>0.05). The lowest concentration of serum lactate dehydrogenase (LDH) was observed in control group (P<0.01). Serum uric acid level decreased in ESM group (P<0.01). OLE supplementation had limited impacts on quail nutrition. Consequently, while the individual usage of OLE and ESM did not show remarkable effects, the mixture of OLE and ESM has been found to positively affect the egg quality and performance parameters.
