Domestic duck

Presentation

The domestic duck is the domesticated form of the mallard (Anas platyrhynchos). Selectively bred by humans for over 4,000 years, it exists in numerous color and body variants adapted for different purposes (meat, eggs, ornament). It is one of the most widespread domesticated birds worldwide.

The domestic duck shows great morphological variability depending on the breed. Its body is stocky with a moderately long neck and rounded head. Plumage can be white, black, brown, pied, or multicolored depending on the variety. Heavy breeds have developed a broad chest and prominent abdomen.

Indicative values: they vary by subspecies, sex and region.

Habitat and distribution

The domestic duck thrives in the presence of water: rivers, lakes, ponds, canals, and even simple basins. It appreciates grassy areas for grazing and shaded areas for resting. In intensive farming, it tolerates dry enclosures with intermittent water access. Proximity to a permanent water source significantly improves its welfare.

Behaviour

The domestic duck is a sociable species that willingly lives in groups. It is semi-aquatic and spends much of its time swimming and feeding at the surface or dabbling. Calm and unafraid, it adapts well to captivity and human proximity. It expresses contentment through characteristic quacking.

Reproduction

The domestic duck reaches sexual maturity between 4 and 6 months depending on the breed. The female typically lays 100 to 300 eggs per year depending on genotype. Incubation lasts about 28 days. Ducklings are precocial and follow the mother shortly after hatching. Breeding can occur year-round under controlled conditions.

Peculiarities

Unlike many wild ducks, domestic males do not develop brilliant plumage in spring. Some breeds have lost the ability to fly due to selection for weight and production. The domestic duck is less vocal than wild species, although females remain talkative. Several old breeds are considered heritage breeds.

Threats and conservation

As a domestic species, the duck has no UICN status. The main risks for farming are infectious diseases (avian flu, fowl cholera), predators, and inadequate rearing conditions. Heritage breeds face genetic decline due to focus on commercial productive breeds.
