Effects of rosemary essential oil supplementation on performances, some serum characteristics and reproductive hormones of male japanese quails

Bu çalışma, Japon bıldırcınlarının (Coturnix coturnix Japonica) karma yemlerine farklı seviyelerde biberiye esansiyel yağ ilavesinin performans parametreleri, bazı serum ölçütleri ile üreme hormonlarına olan etkisini saptamak için yürütülmüştür. Çalışmada hayvan materyali olarak 49 günlük yaşta 60 adet erkek Japon bıldırcını (Coturnix coturnix Japonica) kullanılmıştır. Deneme 4 muamele grubunda 5 tekerrürlü olarak, her bir kafeste 3 adet hayvan bulunan 20 alt grupta, 3 hafta süreyle yürütülmüştür. Çalışmada biri kontrol (0 mg/kg) ve 3’ü farklı seviyede (100, 200 ve 400 mg/kg) biberiye esansiyel yağ katkılı olmak üzere 4 farklı karma yem hazırlanmıştır. Araştırma sonunda erkek bıldırcın karma yemlerine biberiye esansiyel yağ ilavesinin canlı ağırlık kazancı (CAK) ile serum parametrelerinden glikoz üzerine olan etkisinin istatistiki olarak önemli olduğu (P0.05).This study was carried out in order to determine the effect of different levels of rosemary (Rosmarinus officinalis L.) essential oil on performance parameters, some serum characteristics and reproductive hormones of male Japanese quails (Coturnix coturnix Japonica). In the study, 60 male Japanese quails at the age of 49 days were used as animal material. The study was conducted with 5 replications in 4 treatment groups, in 20 subgroups with 3 animals in each cage, for 3 weeks. In the study, 4 different mixed feeds were prepared, one of which was control (0 mg/kg) and 3 of them at different levels (100, 200 and 400 mg/kg) of rosemary essential oil. At the end of the study, it was determined that the effect of rosemary essential oil addition to male quail rations on body weight gain and glucose, among serum parameters, were statistically significant (P<0,05). On the other hand, it was seen that its effect on the other parameters was insignificant (P> 0,05)
