• The egg-laying capacity of the domestic goose increases with age, rising by 15–25% in the second year compared to the first. In the third year, the growth is 30–40%, and in some breeds, it may reach 10–25% even at five years old.
• The domestic goose is capable of increased reproduction. This quality has become an important characteristic in goose breeding, especially in the last 150 years.
• The domestic goose can raise up to 25 goslings in a year, from which 100 kg of meat is obtained. These goslings reach such weight when fattened.

Embryonic development lasts 4 weeks. Litter size is 5–12. Maturity occurs from 10 months to 1 year 6 months. Offspring numbers are 5–12. A male and female form a permanent pair. The female builds a nest on the ground, lays eggs, and incubates them. The male guards the territory. The breeding interval is 1 year. They inhabit and develop on land, outside of water bodies. In a terrestrial nest, eggs, or offspring develop in a nest built on the ground or close to it. Near freshwater, the nest is built on land near a river, lake, pond, or swamp. A caring mother—near freshwater, only the mother shows parental care for the offspring. A ground nest—the nest is located directly on the surface of the soil on land. A caring father—the nest is located directly on the surface of the soil on land, only the father shows parental care for the offspring. Ordinary sexual reproduction—homogamy, reproduction always occurs with fertilization, without a change of generations.
