Abstract
This study was conducted to determine the potential of coriander seed as a natural growth promoting
substance in quail nutrition. Five hundred and ninety four 3-day old Japanese quails were divided into six
groups of 99 birds each and randomly assigned to six treatment diets. Four of the diets containedcoriander
seed at 0.5%, 1%, 2% or 4% levels of inclusion, one contained 10 mg of the antibiotic, avilamycin, per kg
and a control group received no supplement. Effects on feed intake, daily live weight gain, feed conversion
ratio and carcass characteristics of the birds were measured over a period of 42 days. After 42 days the
highest feed intake was observed in the 4% coriander group. Birdsreceiving the diet containing 2%
coriander seed showed the highest weight gain, followed by those receiving the diets containing 1%
coriander seed, the antibiotic, the 4% and the 0.5% coriander seed. The control had the lowest weight gain.
The feed conversion ratio over the experimental period was significantly better in the group receiving 2%
coriander seed than in the other treatments. The highestcarcass yield and liver weights were also recorded in
the 2% coriander group, while the lowest abdominal fat percentages were present in the 1%, 2% and 4%
coriander groups. These results suggested that coriander seeds could be considered a potential natural growth
promoter for poultry, and showed the best responses at a 2% level of inclusion._______________________________________________________________________________________

Introduction
Dietary antibiotics have played an important role in animal production as growth and health promoters.
However, the use of most antibiotic growth promoters has been banned in many countries,especially in the
European Union, because of public concerns about their residues in the animal products and the development
of antibiotics-resistant bacteria (Schwarz et al., 2001; Lee et al., 2004). Consequently, the use of antibiotics
in poultry diets has been curtailed and scientists have been searching for alternatives to antibiotics. In view
of this, aromatic plants and essential oils extractedfrom these plants have become more important due to
their potential antimicrobial and stimulating effects in the animal digestive system. Aromatic plants have
been used traditionally as antiparasitic, anthelmintic, analgesic, expectorant, sedative, antiseptic and antidiabetic substances in many parts of the world (Lee et al., 2004). In addition, they possess antimicrobial
activity, (Elgayyar etal., 2001; Singh et al., 2002; Valero & Salmeron, 2003), biological activities such as
that of antioxidants (Chithara & Leelamma, 1999; Miura et al., 2002) and hypocholesterolemics (Craig,
1999). Recent studies have shown that they have a stimulating effect on the digestive systems of animals,
through the increasing production of digestive enzymes and by improving the utilization of digestiveproducts through enhanced liver function (Langhout, 2000; Williams & Losa, 2001; Hernandez et al., 2004).
Furthermore, limited research has suggested that some aromatic plants and their components could improve
feed intake, feed conversion ratio and carcass yield (Ather, 2000; Bassett, 2000; Hertrampt, 2001; Tucker,
2002).
As an aromatic plant, coriander (Coriandrum sativum L.) is an annual...
