North America, including the United States, Canada, Greenland, Bermuda, Saint Pierre and Miquelon Islands and Mexico in the transition zone between North America and Central America. Eurasia and northern Africa, including the whole of Europe, Africa north of the Tropic of Cancer, Arabian Peninsula and Asia north of Himalayas, Hengduan Mountains, Minshan Mountains, Qinling Mountains and Huaihe River.

Can wild geese swim?

Wild geese can swim. Wild geese live in groups near the water, often in groups of thousands. At night, wild geese are on guard around them. If they encounter attacks, they will call the police. The staple food is tender leaves, fine roots, seeds, and occasionally peck at farmland grains. Every year after the spring equinox fly back to the north breeding, autumn equinox fly south winter.

Why do geese fly south?

Wild geese fly south to winter, the south has a tropical climate, warmer than the north, food will be more abundant than the north, wild geese belong to migratory birds, fly south to winter. Migratory birds are generally migratory habits, with seasonal changes between the winter and breeding grounds of birds, large groups, to and from the time, place are very regular, there are fixed winter sites, breeding grounds and migration sites.

Breeding Value of Wild Goose

Wild goose feathers rich, good at flying, chest muscle developed, per 100 grams of meat protein 20.98 grams, fat 11.62 grams, phosphorus 196.5 mg, calcium 48.04 mg, iron 8.71 mg, inorganic salts 1.17 grams, is a better nutritional protection products. Wild geese also have medicinal functions, which are recorded in detail in more than ten ancient medical books such as Qianjin Food Treatment and Compendium of Materia Medica.

1. Wild goose meat: sweet and flat in nature, returning to lungs, kidneys and liver. Dispel wind and cold, strengthen bones, Yiyang qi, warm water zang.

2. Wild goose fat: Wild goose fat has the effects of activating blood circulation, expelling wind, clearing away heat and detoxifying.

3. Down: The down of wild goose is warm and very soft. It can be used as pillow, cushion, clothing, bedding and other filling materials. The harder feathers can be used to process fans and handicrafts.

Wild goose breeding technology

1. Disinfection of eggs: After eggs are produced, they are often contaminated by grass and feces. There are a small amount of bacteria on the surface. After 30 minutes, bacteria can enter the eggs through shell holes. Therefore, eggs should be disinfected in a timely manner. First put the eggs into the disinfection cabinet, according to 28 ml per cubic meter of formalin solution and 14 grams of potassium permanganate to prepare medicine, formalin into glass or enamel containers (due to the reaction will produce a lot of bubbles, the volume of the container used than the volume of formalin used 5~7 times), then pour potassium permanganate, close the doors and windows, a few minutes later, formaldehyde vapor overflow, 12~24 hours later open the doors and windows, release residual gas, the eggs into the storage room.

Preheating of eggs: preheating of eggs before hatching can make embryos have an adaptation process to the external environment and prevent sweating of eggs. First, potassium permanganate or bacteria poison, hundred poison and other drugs are prepared into the required concentration according to the instructions, the eggs are soaked in the liquid medicine for 3 to 5 minutes, taken out and dried, and placed in an incubation room for preheating for 6 to 8 hours.

3. Temperature and humidity control: the whole batch of eggs incubated at different temperatures is mainly incubated at 30~37℃, and the temperature is gradually reduced from high to low. The eggs incubated in batches are incubated at a constant temperature of 38~38.5℃. The humidity control principle is high at both ends and low in the middle. 1~3 days to maintain 65~70%, 4~28 days to control 60~65%, 29~31 days to 70~75%. In addition, under the condition of ensuring normal temperature and humidity, try to ventilate smoothly. 2. Turn eggs, light eggs and cool eggs. The automatic egg-turning incubator turns the eggs every 2 hours, and the manual or indigenous method turns the eggs every 3 to 4 hours, and the turning angle is 45 to 90 degrees. Wild goose eggs need to be illuminated three times during the whole incubation period. The first time is carried out on the 5th day after hatching, and sperm free eggs and dead eggs are picked out. The second time is carried out on the 10th day, dead embryos are picked out, the causes are found out in time, and the incubation conditions are adjusted. The third time was carried out on the 26th day, mainly to observe the embryo development and determine the time of plate landing. Incubate the machine regularly open the door twice a day, 16 days after incubation will also be from the egg tray rack about 2/3 of the eggs to cool eggs, cool eggs time control within 30 minutes. The eggs can be cooled by reducing mulch and increasing ventilation.

4. Shell-breaking midwifery: The eggshell of wild goose eggs is thicker, the shell-breaking teeth of young geese are not very sharp, and some chicks cannot hatch normally, so midwifery should be timely during hatching. The allantoic blood vessels have withered, yellow inner shell membrane, embryo eggs with scissors, etc. gently open the blunt part of the egg, open about 1/3 of the eggshell, and gently pull out the head of the young goose with hands, put it into the hatchling device to make it self-hatch.

5. Young goose breeding: Young goose refers to the young goose from hatching to full 1 month old. This period is the key stage of artificial domestication. At the same time, due to incomplete digestive function and poor temperature regulation ability of young geese, careful feeding and management are needed.

6. Feeding of medium geese: generally refers to young geese from 4 weeks old to before fattening. During this period, grazing should be given priority to, and appropriate amount of concentrated feed should be supplemented. Grazing in the morning and evening, rest at noon. Grazing to 80 into full after drinking water rest for half an hour before release, grazing 2 to 3 times a day. The optimum number of grazing geese is 250~300. Grazing should be protected from rain and pesticide poisoning. Supplemental concentrate ratio: corn flour 60%, broken barley 12.5%, broken wheat 13.5%, 12.5%, stone powder 1.5%.

7. Fattening geese breeding: medium geese can be fattened and listed when the main feathers grow out. Grazing is the main method, and the individual with large body frame is adopted, and the fattening effect is remarkable. The fattening method can adopt grazing supplementary feeding rice or wheat grains, or can adopt captive feeding grain or root tuber feed, feed 3 to 4 times a day, fattening can be put on the market in half a month, or can be forcibly fed, and the soaked and expanded corn grains can be fed for about 10 days to be put on the market.
