To provide a safe growth promoter, the present study has investigated the effects of different levels of cold-pressed clove oil (CCPO) on growth performance, carcass traits, blood biochemistry, and intestinal microbial population of growing Japanese quails. A total of 300 quails (1-wk old) were randomly divided into 3 treatment groups: control basal diet, basal diet +0.75 mL oil/kg diet, and basal diet +1.5 mL oil/kg diet. Quails fed with 1.5 mL clove oil/kg diet showed a 3.43% improvement in live body weight vs. control group. Similar trend was observed for daily body weight gain. Feed intake gradually increased (P < 0.01) with an increase in clove oil level. The best feed conversion rate was reported for the control group, followed by the group treated with 1.5 mL CCPO/kg diet during the whole period (1 to 6 wk of age). Total globulin differed significantly in 1.5 mL CCPO/kg diet group. Antioxidant enzyme activities, lipid profile, and reduced glutathione concentrations significantly improved in a dose-dependent manner. Blood urea nitrogen, creatinine, malondialdehyde, 8-hydroxy-2'-deoxyguanosine, and protein carbonyl levels significantly decreased in quails supplemented with 1.5 mL CCPO/kg diet vs. control group. Serum levels of insulin-like growth factor-1, insulin, growth hormone, and thyroxine significantly increased in quails supplemented with 1.5 mL CCPO/kg diet vs. control group. The intestinal bacterial population, coliforms, Escherichia coli, and Salmonella spp. in the ileal content were lower (P < 0.05) in groups treated with oil (1.5 mL/kg) vs. control group. Thus, dietary supplementation with antimicrobial CCPO (1.5 mL/kg diet) could enhance growth performance, improve health status, and reduce intestinal pathogens in Japanese quails.

A plant genus in the family Myrtaceae. It is known for cloves, which is the flower bud of Syzygium aromaticum and is the source of an oil rich in EUGENOL.
A plant genus in the family MYRTACEAE, order Myrtales, subclass Rosidae. It is best known for cloves, which is the flower bud that is the source of an oil rich in EUGENOL. The botanical name has varied: Syzygium aromaticum (L.) Merr. & L. M. Perry = Eugenia caryophyllata Thunb. = Caryophyllus aromaticus L. The Eugenia-Syzygium name is discussed in Amer. J. Bot 59:423 1972.
An oil from flower buds of SYZYGIUM trees which contains large amounts of EUGENOL.
A 6-kDa polypeptide growth factor initially discovered in mouse submaxillary glands. Human epidermal growth factor was originally isolated from urine based on its ability to inhibit gastric secretion and called urogastrone. EPIDERMAL GROWTH FACTOR exerts a wide variety of biological effects including the promotion of proliferation and differentiation of mesenchymal and epithelial cells.
A cinnamate derivative of the shikamate pathway found in CLOVE OIL and other PLANTS.
Enzymes are proteins that catalyze (i.e., increase the rates of) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical re...
