| Summary: | <b>Aim:</b> The present study was conducted to determine the effects
of essential oil mixtures rich in carvacrol, alpha-pinene
and cineole supplementation in laying quail diets on performance,
egg quality, and egg lipid peroxidation.<p>
<b>Materials and Methods:</b> A total of 420 (280 females and 140
males) eight-week-old Japanese quails (Coturnix coturnix japonica)
were used. They were divided into 1 control group
and 6 treatment groups containing 60 quails in each. Each
group was divided into four replicate groups each containing
15 quails. The control group was fed basal diet. The diets of
treatment groups occurring from carvacrol (C), alpha-pinene
(P) and cineole (Cn) were supplemented with 100 and 1000
mg/kg essential oil mixed. The experimental period was lasted
for 8 weeks.<p>
<b>Results:</b> The results showed that feed consumption decreased
in the P1000 and Cn1000 groups (P<0.01). Feed conversion
ratio was improved in the C1000, P1000 and Cn1000
groups (p<0.001). The egg yolk malondialdehid level during
storage periods decreased in the P1000 group on the 15th
day (P<0.05) and in the C100, C1000 and P1000 groups on
the 30th day (P<0.001) compared with the control group.<p>
<b>Conclusions:</b> It was concluded that essential oil mixed supplementation
rich in carvacrol or alpha-pinene can be used in
laying quail diets because of these might be positive effect on
feed conversion and the egg lipid peroxidation during storage
periods. |
