The ancestor of the domestic goose is the goose, which was domesticated by humans about three to four thousand years ago. It is bred all over the world. Grass-eating, cold-tolerant, gregarious and disease resistant.

It grows fast and has a longer lifespan than other poultry. Weight 4 15kg, incubation period of one month. It inhabits near ponds and other waters, and is good at swimming.

Geese are poultry that are larger than ducks, with sarcomas on the forehead, long necks, flat and broad beaks, high legs and short tails, webbed toes, and white or gray feathers.

Chicks can eat grass from 1 day old, if conditions permit, should be grazed as much as possible, captive in the house to feed with high-quality grass, can be fed in a combination of concentrate and forage, but also appropriate grazing, so that not only can reduce costs, the most important thing is to promote the growth and development of geese and fattening.

The cold resistance of adult geese is very strong, in the cold winter can also swim in the water, but also in the open air overnight, which is related to the goose's down thick and dense, with a good thermal insulation function, the goose's beak combing feathers will compress the tail fat gland, extruded secretions are coated on the surface of the feathers, which can make the feathers have the characteristics of waterproof and cold, and the subcutaneous fat of the goose is thicker, so that the cold resistance of the goose is enhanced.

In winter, the temperature of the river is slightly higher than that on the shore, and the duck swims constantly in the water, which also increases its body temperature, which plays a role in resisting cold, and the bone marrow coagulation point of the legs and soles of the feet is very low, and the blood on the feet is flowing even if it is in ice water for a long time.

2. To do gymnastics and other preparatory activities, you should gradually adapt to the close range not far from the shore, and you should not swim far away from the shore, and you should have stamina.

3. Patients with heart disease, epilepsy, hypertension and other diseases are not allowed to swim in deep waters, but can swim according to their physical condition when there is a special person to take care of them in the shallow water safety zone.

4.

6. When swimming near a big boat, you must stay at least 10 meters away from the big boat, otherwise the closer you get to the big boat, the easier it is to be sucked into the bottom of the boat.

For beginners, be sure to be in shallow water, and the depth of the water should not exceed the chest. Learn to dive first, then learn to swim, people who lack calcium should not swim to deep water as much as possible, because calcium deficiency is easy to cramp, safety first.
