KR-20260067679-A - Feed additive composition for broiler chickens containing extract of Aurea Helianthus as an effective ingredient

Abstract

The present invention relates to a feed additive for broiler chickens using *Hibiscus syriacus*, and more specifically, to a functional feed additive composition that can improve the quality of chicken meat when fed to broiler chickens using *Hibiscus syriacus* extract as a functional material. When the feed additive composition according to the present invention is fed to broiler chickens, the collagen content in the meat can be increased, thereby providing a meat quality improvement effect and contributing to the production of special and functional high-quality branded meat.

Description

Feed additive composition for broiler chickens containing extract of Aurea Helianthus as an effective ingredient The present invention relates to a feed additive for broiler chickens using goldenrod, and more specifically, to a functional feed additive composition that can improve the quality of chicken meat when fed to broiler chickens using goldenrod extract as a functional material. In recent years, poultry farming, such as chickens and ducks, has been trending toward industrialization and large-scale operations. Consequently, research is being conducted on rearing methods to increase growth rates and maintain the health of livestock while raising them in high-density conditions within limited spaces. As a means to achieve this, feed additives for the healthy rearing of poultry are being researched. These additives aim to prevent diseases and increase production yields, and new feed additives containing synthetic amino acids, vitamin preparations, trace elements, antibiotics, enzyme preparations, hormone secretion promoters, antioxidants, anthelmintics, antifungal agents, and coloring agents are being developed in various forms. Meanwhile, Goldenrod is a plant whose utility is recorded in the *Compendium of Materia Medica*, and it is known as a rare edible and medicinal plant, so much so that it is called the "Panda of the plant kingdom." In traditional Korean medicine, Goldenrod is said to be used to treat gonorrhea and furuncles, as well as for detoxification. Goldenrod contains flavonoids, linoleic acid, oleic acid, vitamin E, selenium, and plant-based collagen. It has been revealed that ethanol extracts of Goldenrod improve diabetic nephropathy, including the reduction of urinary protein. Against this backdrop, the inventors sought to develop a feed additive material that can improve the quality of chicken meat and impart functionality when fed to broiler chickens during rearing. As a result, the present invention was completed by confirming that when a goldenrod ethanol extract alone or ascorbic acid in addition to the extract is fed to broiler chickens as a feed additive, the collagen content in the meat of the broiler chickens is significantly increased. The present invention relates to a feed additive composition for broiler chickens comprising goldenrod powder or goldenrod extract as an active ingredient. In the present invention, the “Hibiscus aureus ( Aurea Helianthus )” is an annual herbaceous plant belonging to the genus Hibiscus. Also known as wild hibiscus, it is a medicinal plant listed in the *Compendium of Materia Medica*. It was restored and began to be cultivated in China, and recently, seeds were introduced from China to Korea, leading to cultivation within the country. By July or August, the Hibiscus aureus grows taller than a person; the flower heads typically have a diameter of 16 to 18 cm. The petals are yellow and pale, the stamens are scarlet, and the leaves are deep blue and full-leaved, making it very beautiful. It is said that harvesting the Hibiscus aureus at the right time is very important because its blooming period is only about six hours. The flowers of the Hibiscus aureus are picked from the end of July, finely shredded, dried, and ground into powder to be used as a raw material for food, cosmetics, and tea. The leaves of the Hibiscus aureus also contain various physiologically active substances and are utilized for various purposes. Goldenrod contains flavonoids, linoleic acid, oleic acid, vitamin E, selenium, and plant-based collagen. It has been revealed that the ethanol extract of goldenrod improves diabetic nephropathy, such as reducing urinary protein. The goldenrod powder according to the present invention can be prepared by thoroughly washing the goldenrod stems and leaves, then drying and grinding them. The extract of *Hibiscus syriacus* according to the present invention may be obtained by extracting and separating from nature using extraction and separation methods known in the art, and the ‘extract’ defined in the present invention is extracted from the stems and leaves of *Hibiscus syriacus* using a suitable solvent, and may include, for example, crude extract of *Hibiscus syriacus*, extracts soluble in polar solvents, or extracts soluble in non-polar solvents. Any pharmaceutically acceptable organic solvent may be used as a suitable solvent for extracting the extract from the above-mentioned goldenrod, and water or organic solvents may be used, but are not limited thereto, various solvents such as purified water, alcohols having 1 to 4 carbon atoms including methanol, ethanol, propanol, isopropanol, butanol, acetone, ether, benzene, chloroform, ethyl acetate, methylene chloride, hexane, and cyclohexane may be used alone or in combination, and preferably, it may be ethanol. As an extraction method, any one of the following may be selected and used: hot water extraction, cold maceration extraction, reflux extraction, solvent extraction, steam distillation,
