supplementation with mixed essential oils and thyme oil
improved the egg production rate by 5.43% and 6.20%,
respectively. However, contrasting results have been reported
by Bozkurt et al. [24] who indicated that a diet supplemented
with EOM had no beneficial effects on egg production or
FCR in laying hens. Similarly, addition of oregano oil [25]
and thyme oil [23] to a layer diet had no significant effects on
FCR. In our study, addition of EOMandANT to the layer diet
had no significant effects on daily feed intake of laying quail.
Although our data is in accordance with that of several preliminary
studies [22, 24–27], it contradicts some other studies
that examined reduced feed intake. Egg weight did not differ
between the different treatment groups. Our findings are in
agreement with those of Bozkurt et al. [24] who studied the
effects of EOM in laying hens. Similar results were reported
by C,abuk et al. [22] who indicated that a diet supplemented
with EOMhad no beneficial effect on egg weight. In contrast
to our results, B¨ol¨ukbas,ı et al. [28] observed that the addition
of essential oils to a layer diet increased eggweight.Theeffects
of EOM and ANT on egg quality characteristics and body
weight are shown in Table 3.
