[INQ. NO. 2512C19] GUARDIZEN, a probiotic supplement developed for companion animals, has been formulated to strengthen intestinal health in dogs and cats by combining two key functional components: a broad probiotic blend and IgY, an immunoglobulin derived from egg yolk. This pairing allows the product to support both digestive balance and immune protection, making it especially valuable for young animals that face heightened susceptibility to infectious diseases before or during their vaccination period.
At the center of the formulation is IgY, an antibody harvested from hens that have been immunized against a range of viral pathogens. For canines, it targets viruses such as CPV, CDV, ICH, CPIV, and CCV, while in felines it offers protection against panleukopenia, rhinotracheitis, and calicivirus. By supplying this form of passive immunity, GUARDIZEN helps bridge the vulnerable stage when puppies and kittens are unvaccinated or experiencing immunological stress.

Complementing this is a blend of seven carefully selected probiotic strains, each chosen for its ability to stabilize the gut microbiome and enhance digestive function. A balanced intestinal environment also plays a crucial role in stress management, which in turn supports broader physical well-being in pets. The product’s daily administration is simple: each one-gram sachet can be mixed directly with food or water, making it easy for pet owners to incorporate into routine care.
GUARDIZEN has already secured a strong foothold in markets across Asia and the Middle East, including Myanmar, Indonesia, Vietnam, Taiwan, Malaysia, the Philippines, and the UAE. Its rapid adoption is largely attributed to its effectiveness, convenience, and palatable flavor, qualities that distinguish it from similar supplements on the market.

GONADON, another leading veterinary product from Dong Bang Co., Ltd., is designed to enhance reproductive efficiency in livestock, with particular emphasis on cattle and swine. The formulation is built around Gonadorelin, a synthetic version of the naturally occurring gonadotropin-releasing hormone produced by the hypothalamus. Once administered, it activates the pituitary gland to release LH and FSH, hormones essential for normal reproductive cycles and healthy fertility.
In dairy cattle, GONADON supports follicular development, encourages estrogen production, and promotes ovulation. It is frequently used to treat ovarian cysts, silent estrus, and delayed ovulation, and it plays a critical role in synchronization programs that coordinate estrus and ovulation to improve breeding efficiency. In swine, particularly in sows, the hormone assists with ovulation induction and estrus synchronization and contributes to improved conception rates, thereby enhancing overall productivity.

What sets GONADON apart is the facility in which it is produced—Korea’s only GMP-certified manufacturing site dedicated solely to hormone pharmaceuticals. This ensures stringent quality control and consistent production standards, complementing the product’s proven clinical effectiveness. Competitively priced and supported through extensive technical and customer resources, GONADON has been welcomed in markets around the world. It is exported widely, including to Vietnam, Myanmar, Sri Lanka, Indonesia, Ukraine, and the UAE. The company’s active participation in international exhibitions and seminars continues to expand its global presence.
Dong Bang Co., Ltd., founded in 1977, has grown into one of Korea’s leading manufacturers of veterinary pharmaceuticals, with a particular reputation for innovation in hormone-based treatments. Its long-standing expertise has positioned the company as a pioneer in animal health, and its expansion in 2016 marked a major milestone: the establishment of a modern GMP facility in Anseong, dedicated exclusively to hormone production and still unmatched in Korea.
The company’s portfolio spans antibiotics, hormones, immune enhancers, probiotics, minerals, and vitamins, with its reproductive hormone products receiving global acclaim for both quality and versatility. Continuous investment in research and development remains central to its mission, supported by a team of veterinary PhD specialists who guide product innovation and uphold scientific rigor.
Dong Bang maintains a dynamic presence not only in Korea but also in international markets throughout Southeast Asia, the Middle East, and Eastern Europe. Its certifications—including GMP, ISO 9001, and various patents—reinforce its commitment to high manufacturing standards and ensure consistent reliability across all product lines. Driven by a vision to advance both animal and human well-being, the company continues to combine technological expertise with dedicated customer support as it expands its role in the global veterinary industry.
