II. Sample Article Exposition on Ducks

Similar to buffalo, cattle, dogs, cats, chickens, and pigs, ducks are also a familiar domesticated species for humans, especially for farmers. In Vietnam, duck farming has become a thriving and distinct industry, bringing high economic benefits. Duck meat, known for its nutritional value, is widely favored. However, not everyone possesses basic knowledge about ducks.

Domestic ducks trace their origins back to the Mallard species (the ancestor of all domestic duck breeds), appearing in ponds and marshes in Asia. They have been present in Southeast Asia for thousands of years, domesticated by humans for food and feathers. Like their relatives, swans, geese, and other ducks, they belong to the waterfowl group (aquatic birds that feed underwater), distinguishing them from other poultry such as birds and chickens. The scientific name for ducks is Anas platyrhynchos domesticus, belonging to the Duck family (Anatidae), Goose order (Anseriformes). In Vietnam, the most common is the grass duck, also known as the free-range duck.

Grass ducks exhibit a variety of feather colors, ranging from pure white and brown with a touch of gray to shades resembling the scent of pandan leaves with tiny black spots. The diverse plumage results from crossbreeding different breeds during free-range farming. Despite the varied colors, they share the common trait of having sleek, thick, and waterproof feathers, allowing them to float and stay warm underwater. Their small bodies, slender chests, long necks, bright and agile eyes, tall legs with webbed feet, and distinctive waddling gait make them a unique and comical sight. However, they move swiftly, swim well, and excel in foraging. Ducks are among the few species capable of moving on land, swimming underwater, and flying with their strong wings, although not for long distances due to their heavy bodies. A notable feature shared by ducks and the entire waterfowl group (Anseriformes) is their flat, long, and robust bills, mostly colored in a yellowish-orange hue, facilitating feeding and water sifting for food. On average, mature drakes weigh around 1.7kg, while females are lighter, approximately 1.5kg.

Ducks lay eggs throughout the year, with mature females capable of laying 150-200 eggs annually. The fertilization rate is remarkably high at around 94.3%, and the hatching rate reaches 81.2%, contributing to ducks being considered a species with good genetic preservation. Typically, ducks are ready for slaughter in 65-70 days when fully feathered, and by 70-80 days, they are suitable for meat production. In recent years, duck farming has thrived in the Red River Delta and Mekong Delta regions, where numerous ponds, marshes, rivers, and extensive rice fields provide abundant food resources for ducks after the harvest season.

In terms of economic value, grass ducks have increasingly dominated total poultry production, supplying food for both domestic consumption and export. Duck meat is rich in nutrients, containing high levels of protein, iron, phosphorus, calcium, and various vitamins. It has a sweet, firm, and aromatic taste, suitable for preparing a wide range of dishes from simple to gourmet. In traditional medicine, duck meat is considered sweet and cool, used to nourish and balance the body, beneficial for individuals with internal heat imbalances or prolonged fever symptoms. Duck eggs are also a common daily food item, used in various baking recipes.

Domestic ducks have become a familiar poultry breed, seemingly an emblem of rural Vietnam, especially in watery regions. Ducks not only contribute to the economic value and income enhancement for farmers without requiring extensive farming techniques, but they also bring delicious dishes, enriching the authentic flavors of Vietnamese cuisine. Missing out on the experience of tasting boiled duck dipped in ginger fish sauce would be truly regrettable, particularly in watery regions.
