Clove (Syzygium aromaticum) in poultry feed

ABSTRACT

The species, herbs, vegetables, and some plants have a role as growth promoters in broiler diets to improve the efficiency of the growth conversion and reduce the cost of feed. Adding herbal plants as growth promoters in broiler diets improves their feed conversion ratio, mortality rate, and body weight gain. Clove (Eugenia caryophyllus, syn. Syzygium aromaticum) is considered as a spice and appetizer. It contains 10% volatile oil, most of which is eugenol. Clove extract is commonly used in the food industry because of its unique aroma and natural safety. In addition, clove essential oil exhibited strong antibacterial properties. Antiseptic, appetite and digestion stimulant, anti-inflammatory, and antioxidant activities of clove and its ingredients have been reported. However, clove essential oil has been studied by very few as a performance enhancer of poultry. The discussion will cover those preventing specific pathogenic microorganisms and increasing some beneficial microorganisms in intestinal microflora. Regarding the role of clove as feedstuff and the role of clove as an alternative additive, the mechanisms are beginning to be understood. © 2022 Elsevier Inc. All rights reserved.
